PART I

Item 1. Business.

Overview

We are a ~~clinical-stage~~ biotechnology company pioneering treatments for autoimmune and severe inflammatory diseases, which we collectively refer to as autoimmune diseases. Our approach seeks to redefine the treatment of autoimmune diseases by focusing on critical biological pathways shared across multiple ~~diseases~~indications. We believe that this approach, which targets the underlying molecular pathogenesis of the disease, allows us to develop more precise therapies, identify patients more likely to respond to treatment and pursue multiple indications for each of our product candidates. Our lead ~~product~~molecule ~~candidate,~~ inebilizumab, is a humanized monoclonal antibody, or mAb, designed to target CD19, a molecule expressed on the surface of a broad range of immune system B cells. In January 2019, we reported positive pivotal clinical trial data for inebilizumab in patients with neuromyelitis optica spectrum disorder, or NMOSD. NMOSD is a rare, devastating condition that attacks the optic nerve, spinal cord and brain stem, and often leads to irreversible blindness and paralysis. We received Breakthrough Therapy Designation for the treatment of this disease from the U.S. Food and Drug Administration, or the FDA, in April 2019 and in August 2019, the FDA accepted for review our Biologics License Application, or BLA for inebilizumab. ~~The~~On ~~FDA set a Prescription Drug User Fee Act, or PDUFA date of~~ June 11, 2020~~. In addition~~, wethe ~~have~~FDA aapproved ~~broad pipeline of two additional clinical and two pre~~Uplizna® (inebilizumab-~~clinical~~cdon) ~~stage~~for ~~product~~the ~~candidates~~treatment ~~focused on a number~~ of ~~other~~adult ~~autoimmune~~patients ~~diseases~~ with ~~high~~NMOSD ~~unmet~~who ~~medical~~are ~~needs, including myasthenia gravis, IgG4~~anti-~~related~~AQP4 ~~disease,~~antibody ~~Sjögren’s~~positive ~~syndrome and lupus,~~ as ~~well~~a astwice-a-year ~~other~~maintenance ~~conditions~~regimen ~~such~~following asinitial ~~kidney transplant rejection~~doses. InWe ~~December~~commercially ~~2019,~~launched weUplizna® following ~~initiated~~FDA aapproval ~~Phase~~in 2bJune ~~trial of VIB4920, for the treatment of Sjögren’s syndrome~~2020.

Regulatory applications have also been filed in several other countries for inebilizumab in patients with NMOSD, based on results from the N-MOmentum trial. In October 2020, a BLA was accepted by the National Medical Products Administration in China. In June and September 2020, respectively, a marketing authorization application, or MAA, was filed in Japan and South Korea, and an MAA with the European Medicines Agency, or EMA, was filed in December 2020. If approved, Mitsubishi Tanabe Pharma Corporation (“MTPC”) and Hansoh Pharma, our partners in Asia, will be responsible for commercializing inebilizumab in their respective territories, and we will be eligible for payments based on certain commercial milestones, as well as royalties on sales revenue.

Furthermore, we recently initiated a Phase 3 trial of inebilizumab for myasthenia gravis, a neuromuscular disorder caused by autoantibodies against acetylcholine receptors or muscle specific kinase and a Phase 3 trial of inebilizumab for IgG4-related disease, a group of disorders marked by tumor-like swelling and fibrosis of affected organs, which may be caused by infiltration of CD19-expressing plasmablasts and plasma cells that generate IgG4 antibodies. We are continuing to enroll patients in both of these trials.

In addition, we have a broad pipeline of two additional clinical-stage and two pre-clinical product candidates focused on a number of other autoimmune diseases with high unmet medical needs, including Sjögren’s syndrome and lupus, as well as other conditions such as kidney transplant rejection. A Phase 2b trial in Sjögren’s syndrome, which is designed as Phase 3-enabling, is ongoing and in 2019, we initiated a separate Phase 2 trial in kidney transplant rejection. We are currently advancing two candidates through pre-clinical studies. For the first candidate, VIB1116, we completed pre-clinical toxicology studies and have submitted an IND in Q4 2020.

In December 2019 an outbreak of a novel strain of coronavirus was identified in Wuhan, China. This virus continues to spread globally, has been declared a pandemic by the World Health Organization and has spread to over 200 countries, including the United States. The impact of this pandemic has been and will likely continue to be extensive in many aspects of society, which has resulted in and will likely continue to result in significant disruptions to businesses and capital markets around the world. The extent to which the coronavirus impacts us will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the coronavirus and the actions to contain the coronavirus or treat its impact, among others. At present, we are not experiencing significant impact or delays from COVID-19 on our business and operations. However, in order to prioritize patient health and that of the investigators at clinical trial sites, we had paused enrollment of new patients in certain of our clinical trials, including our Phase 2b trial of VIB4920 in Sjögren’s syndrome, our Phase 2 trial of VIB4920 in rheumatoid arthritis and our Phase 2 trial of inebilizumab in kidney transplant desensitization. We resumed all of our trials except the Phase 2 trial of inebilzumab in kidney transplant desensitization. Our ability to re-open enrollment, and continue enrollment, in our paused clinical trial will be dependent on many factors, including the progression of the pandemic and its impact on patients and the investigators at our clinical trial sites. Furthermore, our ability to re-open enrollment, and continue enrollment, in our paused clinical trial will require collaboration with, and permission from, each of the clinical trial sites. Over the coming weeks and months, we will continue to monitor carefully the situation with respect to each of our clinical trials and follow guidance from local and federal health authorities. Additionally, we believe that the pandemic has impacted the frequency of patient visits to physicians and has impacted physician office operations. These changes may impact prescribing rates of Uplizna^® or other products, if approved.

Our pipeline is currently focused on the following shared critical biological pathways of autoimmune diseases:

•

Production of autoantibodies: the autoantibody pathway. A number of autoimmune diseases, including NMOSD, myasthenia gravis and IgG4-related disease, and other conditions such as kidney transplant desensitization, are associated with autoantibodies secreted by a subset of immune B cells known as plasmablasts and plasma cells. These autoantibodies attack native tissues as opposed to foreign pathogens. Our lead product candidate, inebilizumab, is designed to target and deplete CD19-expressing B cells, which may reduce autoantibodies that are implicated in these autoimmune diseases and other conditions.

•

Immune overactivation through co-stimulatory pathways: the CD40/CD40L co-stimulatory pathway. A number of autoimmune diseases, including Sjögren’s syndrome, and other conditions such as kidney transplant rejection, are associated with overactivation of immune cells through cell-cell, or co-stimulatory, interactions. CD40 ligand, or CD40L, is a soluble or surface-bound protein expressed on T cells that interacts with CD40, a receptor protein expressed on a variety of immune cells such as B cells, dendritic cells and macrophages. The overstimulation of these immune cells triggered by the interaction of CD40 and CD40L, or CD40/CD40L, leads to an immune response cascade and overproduction of molecules that mediate inflammation, resulting in the development of numerous autoimmune diseases. Our second product candidate, VIB4920, is a fusion protein designed to target CD40L, blocking CD40L’s interaction with CD40 and other binding partners, and thereby potentially decreasing autoimmune and inflammatory responses. VIB4920 has been designed to avoid thromboembolic side effects observed with an earlier generation CD40L mAb.

•

Overactivation of the innate immune system: the innate cytokine pathway. A number of autoimmune diseases, including systemic lupus erythematosus, or SLE, cutaneous lupus erythematosus, or CLE, Sjögren’s syndrome, systemic sclerosis, polymyositis and dermatomyositis, are associated with the overproduction of pro-inflammatory cytokines secreted by plasmacytoid dendritic cells, or pDCs. pDCs are a type of innate immune cell that can produce large amounts of cytokines, including type I interferons, IL-6 and TNF-a, in response to immune stimuli such as viral infection, immune complexes and cell debris. Our third product candidate, VIB7734, is designed to target and bind to an immunoglobulin-like transcript, or ILT7, which is a cell surface molecule specific to pDCs, leading to their depletion.

In addition to the three pathways listed above, we are continuing to explore other critical shared biological pathways that we believe are implicated in autoimmune disease pathogenesis.

32021 Merger Agreement

On January 31, 2021, we entered into a definitive Agreement and Plan of Merger (the “Merger Agreement”), with Horizon Therapeutics USA, Inc., a Delaware corporation (“Parent”), Teiripic Merger Sub, Inc., a Delaware corporation and a direct wholly owned subsidiary of Parent (“Purchaser”), and solely for purposes of Sections 6.7 and 9.12 of the Merger Agreement, Horizon Therapeutics plc, a public limited company organized under the laws of Ireland (“Ultimate Parent”), pursuant to which Parent, through Purchaser, will commence a tender offer (the “Offer”) to acquire all of the outstanding shares of our common stock, par value $0.001 per share (the “Shares”), at a price of $53.00 per share in cash, which represents a fully diluted equity value of approximately $3.05 billion, without interest, subject to any applicable withholding taxes. Parent and Purchaser commenced the Offer on February 12, 2021 and are obligated to keep the Offer open for twenty business days following the commencement of the Offer, subject to possible extension under the terms of the Merger Agreement. If successful, upon the terms and conditions set forth in the Merger Agreement, the Offer will be followed by a merger of Purchaser with and into the Company, with the Company continuing as the surviving corporation and as a direct wholly owned subsidiary of Parent (the “Merger”).

Completion of the Offer is subject to the satisfaction or waiver of customary conditions, including (i) there shall have been validly tendered (not including any Shares tendered pursuant to guaranteed delivery procedures that have not yet been “received,” as such term is defined in Section 251(h) of the General Corporation Law of the State of Delaware (the “DGCL”), by the depositary for the Offer pursuant to such procedures) and not validly withdrawn Shares that, considered together with all other Shares (if any) beneficially owned by Parent and its subsidiaries, represent one more Share than 50% of the total number of (A) Shares outstanding at the time of the expiration of the Offer plus (B) the aggregate number of Shares issuable to holders of options to purchase Shares (the “Company Options”) from which we have received notices of exercise prior to the expiration of the Offer (and as to which Shares have not yet been issued to such exercising holders of Company Options); (ii) subject to certain materiality exceptions, the truth and accuracy of certain representations and warranties made by us contained in the Merger Agreement; (iii) compliance with, or performance of, in all material respects the covenants and agreements with or of which we are required to comply or perform; (iv) the termination or expiration of any applicable waiting period (and extensions thereof) relating to the Offer under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended; (v) the absence of a material adverse

effect on us; and (vi) certain other customary conditions set forth in the Merger Agreement. The Offer and the Merger are not subject to any financing condition.

We expect the Merger to close by the end of first quarter of 2021, subject to the regulatory approvals and other customary closing conditions described above and in the Merger Agreement.

Additional information about the Merger and related transactions is set forth in our filings with the Securities and Exchange Commission, or the SEC.

Our Pipeline

We are leveraging our critical biological pathway approach to develop a broad pipeline of product candidates across multiple diseases, which we refer to as indications. The following table summarizes our pipeline:

~~Inebilizumab.~~(1) We ~~are~~have ~~initially~~entered ~~developing~~into ~~inebilizumab~~collaboration asagreements a potential first-line monotherapy for NMOSD. In January 2019, we announced positive topline data from our N-MOmentum pivotal trial in a broad patient population that included AQP4 antibody positive, or AQP4+, and AQP4 antibody negative, or AQP4-, patients with ~~various~~Hansoh ~~degrees~~Pharmaceutical ofGroup ~~disease~~Company ~~severity~~Limited based on the number of previous attacks. AQP4+ patients, characterized by the presence of autoantibodies to a water channel protein called aquaporin-4, or AQP4, are thought to represent approximately 80% of the NMOSD patient population. Inebilizumab is designed to be dosed with two initial doses on days 1 and ~~15,~~Mitsubishi ~~followed~~Tanabe byPharma ~~dosing~~Corporation ~~every six months thereafter, which is a significantly less frequent dosing regimen compared~~ to ~~other~~develop ~~therapies that have been approved or are in clinical development.

Based on the results of the N-MOmentum trial, we submitted a BLA to the FDA in June 2019, which the FDA accepted for review in August 2019. The FDA granted Orphan Drug Designation for inebilizumab for the treatment of patients with NMOSD in February 2016 and ~~Breakthrough~~Japan ~~Therapy Designation in April 2019~~ and inother ~~August~~Asian ~~2019~~countries, ~~the FDA accepted for review our Biologics License Application, or BLA for inebilizumab~~respectively. The FDA set a Prescription Drug User Fee Act, or PDUFA date of June 11, 2020. The European Medicines Agency, or EMA, granted orphan designation to inebilizumab for the treatment of NMOSD in March 2017.

Inebilizumab. We have initially developed inebilizumab as a potential first-line monotherapy for NMOSD. In January 2019, we announced positive topline data from our N-MOmentum pivotal trial in a broad patient population that included AQP4 antibody positive, or AQP4+, and AQP4 antibody negative, or AQP4-, patients with various degrees of disease severity based on the number of previous attacks. AQP4+ patients, characterized by the presence of autoantibodies to a water channel protein called aquaporin-4, or AQP4, are thought to represent approximately 80% of the NMOSD patient population. Inebilizumab is designed to be dosed with two initial doses on days 1 and 15, followed by dosing every six months thereafter, which is a significantly less frequent dosing regimen compared to other therapies that have been approved or are in clinical development. The trial met its primary and a majority of secondary endpoints, and in May 2019, we presented detailed trial data at the plenary session of the Annual Meeting of the American Academy of Neurology. Based on the results of the N-MOmentum trial, we submitted a BLA to the FDA in June 2019, which the FDA accepted for review in August 2019. The FDA granted Orphan Drug Designation for inebilizumab for the treatment of patients with NMOSD in February 2016 and Breakthrough Therapy Designation in April 2019 and in August 2019, the FDA accepted for review our Biologics License Application, or BLA for inebilizumab. The FDA set a Prescription Drug User Fee Act, or PDUFA date of June 11, 2020. The European Medicines Agency, or EMA, granted orphan designation to inebilizumab for the treatment of NMOSD in March 2017.

If we obtain approval from the FDA of inebilizumab as a monotherapy for NMOSD, we intend to focus our commercial efforts initially on the United States market, which we believe represents the largest market opportunity, as we estimate that there are approximately 10,000 patients with NMOSD. We are currently building our internal commercialization capabilities that we expect will initially be supplemented by fewer than 30 clinical sales representatives targeting a small number of medical centers of excellence, where approximately 70% of all patients with NMOSD in the United States are treated. For markets outside the United States, we intend to seek to enter into arrangements with third parties to pursue regulatory approval and commercialization of inebilizumab for the treatment of patients with NMOSD. In May 2019, we entered into a collaboration with Hansoh Pharmaceutical Group Company Limited, or Hansoh Pharma, for co-development and commercialization of inebilizumab in patients with NMOSD and other autoimmune diseases and hematological cancers in China, Hong Kong and Macau, and in October 2019, we entered into a license agreement with Mitsubishi Tanabe Pharma Corporation, or MTPC, for co-development and commercialization of inebilizumab in Japan, Thailand, South Korea, Indonesia, Vietnam, Malaysia, Philippines, Singapore, and Taiwan. 5

Regulatory applications have also been filed in several other countries for inebilizumab in patients with NMOSD, based on results from the N-MOmentum trial. In October 2020, a BLA was accepted by the National Medical Products Administration in China. In June and September 2020, respectively, a marketing authorization application, or MAA, was filed in Japan and South Korea, and an MAA was filed with the European Medicines Agency, or EMA, in December 2020. If approved, Mitsubishi Tanabe Pharma Corporation (“MTPC”) and Hansoh Pharma, our partners in Asia, will be responsible for commercializing inebilizumab in their respective territories, and we will be eligible for payments based on certain commercial milestones, as well as royalties on sales revenue.

VIB4920. VIB4920 is a fusion protein designed to bind to CD40L on activated T cells, blocking their interaction with CD40-expressing B cells and potentially other binding partners. This is intended to prevent B cells from differentiating into plasma cells and memory B cells. Blocking CD40 and CD40L interaction can also inhibit stimulation of dendritic cells and monocytes by T cells, which reduces production of pro-inflammatory mediators. We believe that these combined effects have the potential to produce powerful immunomodulation for the targeting of both T and B cell-driven diseases.

Two Phase 1 clinical trials of VIB4920 have been completed to date: a Phase 1a single-ascending dose trial in healthy volunteers and a Phase 1b multiple-ascending dose trial in patients with rheumatoid arthritis. In both trials, VIB4920 was generally well-tolerated, with no evidence of platelet aggregation that resulted in thromboembolic side effects with an earlier generation CD40L mAb. In the Phase 1b trial, VIB4920 decreased disease activity in patients with active rheumatoid arthritis, and the majority of patients achieved low-level disease activity or remission at the two highest dose levels. We believe that the dose-dependent reduction in autoantibody levels coupled with the clinical activity observed in rheumatoid arthritis suggest that VIB4920 may effectively block the CD40/CD40L interaction. We have selected two diseases associated with immune overactivation through CD40L as the initial diseases to further evaluate in VIB4920 trials. A Phase 2b trial in Sjögren’s syndrome, which is designed as Phase 3-enabling, is now ongoing and in 2019, we initiated a separate Phase 2 trial in kidney transplant rejection. WeFurthermore, ~~also~~a ~~plan~~Phase to2 ~~initiate~~trial ~~additional~~of ~~clinical~~VIB4920 ~~trials~~ in ~~other~~rheumatoid ~~diseases~~arthritis ~~associated~~is ~~with the same pathway in 2020~~ongoing.

VIB7734. VIB7734 is a humanized mAb intended to be a novel treatment for autoimmune diseases where the pathology is driven principally by overproduction of type I interferons and other cytokines secreted by pDCs. VIB7734 is designed to target and bind to ILT7, a cell surface molecule specific to pDCs, leading to their depletion. pDCs generate large amounts of interferons in pathological states. The depletion of pDCs may also decrease other inflammatory cytokines such as TNF-a and IL-6, which are critical to the pathogenesis of a number of autoimmune diseases. We have completed a Phase 1a single-ascending dose trial in patients with any one of the following six autoimmune diseases: SLE, CLE, Sjögren’s syndrome, systemic sclerosis, polymyositis and dermatomyositis. The Phase 1a trial demonstrated that VIB7734 was generally well-tolerated and reduced pDC levels. ~~Our~~In ~~ongoing~~November 2020, we reported the final data from our Phase 1b ~~multiple~~trial ~~ascending~~with ~~dose~~VIB7734 ~~trial~~in ~~includes~~an aoral ~~cohort~~presentation at the American College of ~~patients~~Rheumatology Convergence 2020.

Our Team and Corporate History

We have an experienced internal research and development team focused on utilizing our deep understanding of autoimmune disease pathways to discover and develop novel therapies that more precisely target these pathways. Our founding management team, as well as a significant portion of our research and development team, joined us from MedImmune, the biologics division of AstraZeneca, where they played key roles in the autoimmune disease area and in the development of the product candidates in our existing portfolio. We believe this deep experience with and detailed technical knowledge of both the autoimmune disease area and our product candidates is a critical advantage for us.

Since our founding, we have expanded our team to incorporate additional expertise as needed to pursue our goal of becoming a fully-integrated biopharmaceutical company. We have assembled key management team members with 6

In October 2019, we completed an initial public offering, or the IPO of our common stock and issued and sold 9,085,000 shares of common stock at a public offering price of $19.00 per share, for aggregate gross proceeds of $172.6 million.

Our Strategy

Our vision is to become a fully integrated biopharmaceutical company pioneering treatments for autoimmune diseases by focusing on critical biological pathways shared across multiple indications. Key components of our business strategy include the following:

• ~~Obtain~~Successfully ~~regulatory approval for and successfully~~ commercialize ~~inebilizumab~~Uplizna® as a first-line monotherapy treatment for patients with NMOSD. We received Breakthrough Therapy Designation for inebilizumab for the treatment of NMOSD in April 2019, and in August 2019, the FDA accepted for review our BLA for inebilizumab. ~~The~~On June 11, 2020, the FDA ~~set~~approved aUplizna® ~~PDUFA~~(inebilizumab-cdon) ~~date~~for the treatment of ~~June~~adult ~~11,~~patients ~~2020~~with NMOSD who are anti-AQP4 antibody positive as a twice-a-year maintenance regimen following initial doses. IfWe ~~approved,~~commercially welaunched Uplizna® following FDA approval in June 2020. We believe that we can effectively continue to commercialize inebilizumab in the United States with a focused commercial team targeting a small number of medical centers of excellence that treat approximately 70% of the estimated 10,000 patients with NMOSD. In addition to our collaboration with Hansoh Pharma and MTPC, we are evaluating potential additional partnerships to pursue regulatory approval and commercialization of inebilizumab in NMOSD in other geographic regions outside of the United States.

• Expand the use of inebilizumab into additional diseases. With the positive data from our pivotal trial in NMOSD, which we believe validates inebilizumab’s mechanism of action of targeting the autoantibody pathway, we plan to expand the use of inebilizumab to other diseases where CD19-expressing B cells are believed to be key drivers of the disease pathogenesis. Based on our extensive understanding of the autoantibody pathway, we ~~plan~~recently toinitiated ~~initiate~~a ~~clinical~~Phase ~~trials~~3 intrial of inebilizumab for myasthenia gravis, a neuromuscular disorder caused by autoantibodies against acetylcholine receptors or muscle specific kinase and a Phase 3 trial of inebilizumab for IgG4-related disease, a group of disorders marked by tumor-like swelling and ~~kidney~~fibrosis ~~transplant~~of ~~desensitization.~~affected Weorgans, ~~initiated~~which ~~the~~may ~~first~~be caused by infiltration of ~~these~~CD19-expressing ~~clinical~~plasmablasts ~~trials~~and inplasma ~~kidney~~cells ~~transplant~~that ~~desensitization~~generate inIgG4 ~~2019~~antibodies.

• Rapidly advance VIB4920 and VIB7734 through clinical development for multiple diseases with shared critical biological pathways. VIB4920 demonstrated proof of concept in rheumatoid arthritis in a Phase 1b trial. A Phase 2b trial in Sjögren’s syndrome, which is designed as Phase 3-enabling, is ongoing and in 2019, we initiated a separate Phase 2 trial in kidney transplant rejection. Both of these diseases are associated with immune overactivation through the CD40/CD40L co-stimulatory pathway. We also plan to initiate additional clinical trials in other diseases associated with the same pathway in 2020. VIB7734 is in an ongoing Phase 1b trial, with an interim dataanalysis in patients with CLE expected in the second quarter of 2020. Assuming this trial is able to establish proof of concept, we intend, subject to regulatory feedback, to move into Phase 2 clinical trials in diseases driven by interferons and other pro-inflammatory cytokines secreted by pDCs.7

Discover and develop additional product candidates for the treatment of autoimmune diseases utilizing our critical biological pathway approach. Our team has extensive experience in discovery research, deep expertise in immunology and a strong record of publication in high-impact peer-reviewed journals. The team is focused on understanding additional disease pathways associated with autoimmune disease, identifying key targets for intervention within these pathways and generating drug candidates against those targets. We may also in-license from or collaborate with third parties to develop drug candidates that we believe are promising therapeutic candidates.

Autoimmune Disease Overview

Autoimmune diseases result from an immune response directed against the body’s own healthy cells and tissues. According to a 2012 report from the National Institutes of Environmental Health Sciences, approximately 23.5 million people in the United States suffer from autoimmune diseases. In a significant subset of severe autoimmune diseases there remain substantial unmet medical needs, as patients are generally treated with broadly prescribed steroids and nonspecific immunosuppressive regimens. Current therapies are rarely considered curative and, even with modern standards of care, patients may suffer from chronic disease progression. There is a need for more targeted treatments with increased efficacy and decreased toxicity.

Autoimmune diseases usually involve autoreactive T cells and B cells, which can communicate through shared pathways, resulting in damage to the body’s cells and tissues. In a healthy individual, as the immune system develops during childhood, these T cells and B cells are eliminated or suppressed by various mechanisms. When any of these mechanisms fails, autoimmunity can arise. The presence of autoantibodies, a product of autoreactive B cells, is a hallmark of many of these diseases. Many autoimmune diseases are characterized by disease flares, in which symptoms worsen, followed by a period of remission, in which symptoms improve. Many autoimmune diseases are characterized by progressively worsening health status and life-altering disability.

Certain autoimmune diseases are not only due to the direct effects of autoantibodies, but also other mechanisms that cause immune dysfunction. These include activation of inflammatory T cells and cytotoxic T cells, which can cause inflammation and tissue damage. Cytokines released as a result of immune overactivation can further increase inflammatory tissue damage. Dysregulation of the same pathway can lead to a variety of symptoms, and multiple pathways may be dysregulated in any given autoimmune disease.

In many autoimmune diseases, existing therapy consists of long-term treatment with a combination of immunosuppressive agents and high-dose corticosteroids. These treatment regimens may result in increased rates of infection, increased risk of malignancy, and other side effects, including hypertension, diabetes and osteoporosis. Further, these currently available treatments often do not achieve adequate clinical responses. Targeted agents, such as TNF-a antagonists, are used to treat certain autoimmune diseases, such as rheumatoid arthritis, after immunosuppressive agents have failed. However, these therapies are not effective in treating many autoimmune diseases and, consequently, there remains a substantial unmet medical need for more effective therapies.

Our Approach: Developing Therapies by Focusing on Shared Critical Biological Pathways of Autoimmune Diseases

We seek to redefine the treatment of autoimmune diseases by focusing on critical biological pathways shared across multiple diseases. We believe this approach permits us to develop novel therapies that more precisely target these pathways. We have initially focused on three pathways: the autoantibody pathway, the CD40/CD40L co-stimulatory pathway and the innate cytokine pathway, each of which we believe presents distinct mechanisms that drive autoimmune disease and can be targeted by our existing portfolio of product candidates. The following graphic illustrates each of these pathways and the molecules within these pathways that we are currently targeting.

Autoantibody Pathway. In the autoantibody pathway, autoantibodies are secreted by a subset of immune system B cells known as plasmablasts and plasma cells. In certain cases, these autoantibodies are directly pathogenic. In addition, B cells may contribute to autoimmunity through other mechanisms such as antigen presentation or cytokine production. A number of autoimmune diseases are associated with the B cell-mediated autoantibody pathway, including NMOSD, myasthenia gravis and idiopathic thrombocytopenic purpura, or ITP. B cells also play an important role in kidney transplant desensitization and IgG4-related disease.

Our lead ~~product candidate~~molecule, inebilizumab, is designed to target these antibody-secreting cells by binding with high affinity to CD19 and depleting CD19-expressing B cells via antibody dependent cellular cytotoxicity, or ADCC, and antibody dependent cellular phagocytosis, or ADCP. CD19 is a molecule broadly expressed on B cells, including some antibody-secreting plasmablasts and plasma cells. In contrast, the expression of CD20, another cell surface molecule expressed on B cells, is lost as B cells differentiate into plasmablasts and plasma cells. Unlike existing CD20 targeting therapies, inebilizumab also directly depletes CD19-expressing plasmablasts and some plasma cells, most of which are not able to be directly targeted by anti-CD20 mAbs.

CD40/CD40L Co-stimulatory Pathway. T cells interact with B cells, macrophages and endothelial cells through various co-stimulatory receptor-ligand interactions, including CD40/CD40L. CD40L is thought to be a component of immune responses involved in B cell activation, maturation and eventually antibody production. CD40L also mediates activation of macrophages, dendritic cells and stromal cells, including endothelial cells. A number of autoimmune diseases, such as Sjögren’s syndrome, ITP, SLE, type 1 diabetes and bullous pemphigoid, are associated with overactivation of the CD40/CD40L co-stimulatory pathway. This pathway may also be important in kidney transplant rejection and certain glomerular kidney diseases. Our second product candidate, VIB4920, is a fusion protein designed to target CD40L, blocking CD40L’s interaction with CD40 and potentially other binding partners, thereby potentially decreasing autoimmune and inflammatory responses. VIB4920 has been designed to avoid thromboembolic side effects observed with an earlier generation CD40L mAb.

Innate Cytokine Pathway. Specialized innate immune system cells called pDCs recognize and become activated by viral infection and immune complexes. Upon becoming activated, pDCs produce large amounts of innate cytokines such as type I interferons, IL-6 and TNFa and also help activate other arms of the immune system, including T cells and B cells. A number of autoimmune diseases, such as CLE, SLE, Sjögren’s syndrome, systemic sclerosis, polymyositis, and dermatomyositis, are associated with the overproduction of these innate cytokines. Our third product candidate, VIB7734, is a humanized mAb designed to target and bind to ILT7 on pDCs, leading to their depletion.

Our Product Candidates

Inebilizumab: Our Humanized Monoclonal Antibody for Patients with NMOSD and Additional Diseases that Share the Autoantibody Pathway

We are initially developing inebilizumab as a first-line monotherapy for NMOSD. NMOSD is a rare, severe, relapsing, neuroinflammatory autoimmune disease that attacks the optic nerve, spinal cord and brain stem, often leading to blindness and paralysis. We designed our N-MOmentum pivotal trial to evaluate inebilizumab as a monotherapy across a broad range of disease severity and patients, including both AQP4+ and AQP4- patients. Inebilizumab is designed to be dosed with two initial doses on days 1 and 15, followed by dosing every six months thereafter, which is a significantly less frequent dosing regimen compared to other therapies that have been approved or are currently in clinical development. The FDA granted Orphan Drug Designation for inebilizumab for the treatment of patients with NMOSD in February 2016 and Breakthrough Therapy Designation in April 2019. The EMA granted orphan designation to inebilizumab for the treatment of patients with NMOSD in March 2017.

In January 2019, we announced positive topline data from our N-MOmentum pivotal trial. The trial met its primary and a majority of secondary endpoints, and in May 2019, we presented detailed trial data at the plenary session of the Annual Meeting of the American Academy of Neurology. The N-MOmentum trial is a randomized, double-blinded, placebo-controlled, global registration trial that enrolled 231 patients with NMOSD, which is the largest controlled trial conducted in this indication. The primary analysis demonstrated a 77.3% reduction in the risk of developing an NMOSD attack in AQP4+ patients treated with inebilizumab monotherapy compared to placebo. Furthermore, secondary analyses demonstrated statistically significant reductions in worsening of disability, hospitalizations and new MRI lesions. Inebilizumab was generally well-tolerated, with an adverse event rate similar to placebo. Based on the results of the N-MOmentum trial, we submitted a BLA to the FDA in June 2019, which the FDA accepted for review in August 2019. ~~The~~On June 11, 2020, the FDA ~~set~~approved aUplizna® ~~PDUFA~~(inebilizumab-cdon) ~~date~~for the treatment of ~~June~~adult ~~11,~~patients ~~2020~~with NMOSD who are anti-AQP4 antibody positive as a twice-a-year maintenance regimen following initial doses. We commercially launched Uplizna® following FDA approval in June 2020

In addition to NMOSD, we initiated, ~~or plan to initiate, pending the development of clinical study protocols and subject to regulatory feedback,~~ multiple clinical trials of inebilizumab in other indications associated with CD19-expressing B cells, including:

•

a Phase 2 trial in 2019 for kidney transplant desensitization, where high levels of alloantibodies in certain patients may preclude successful identification of a match and transplant commenced with screening of the first patient;

• a ~~pivotal~~Phase 3 trial ~~in mid-year 2020~~ for myasthenia gravis, a neuromuscular disorder caused by autoantibodies against acetylcholine receptors or muscle specific kinase and

• a Phase 2b3 trial ~~in mid-year 2020~~ for IgG4-related disease, a group of disorders marked by tumor-like swelling and fibrosis of affected organs, which may be caused by infiltration of CD19-expressing plasmablasts and plasma cells that generate IgG4 antibodies.

Mechanism of Action

A number of autoimmune diseases, including NMOSD, are associated with autoantibodies secreted by plasmablasts and some plasma cells. B cells may contribute to autoimmunity through other mechanisms such as antigen presentation or cytokine production. CD19 is a cell surface molecule broadly expressed on B cells, including some antibody-secreting plasmablasts and plasma cells. Each of the graphics below illustrates a different role of CD19-expressing B cells in the pathogenesis of autoimmune disease and other inflammatory conditions. Graphic A shows the process by which B cells differentiate into antibody secreting cells, including plasmablasts and plasma cells. Graphic B reflects the process by which an antigen is presented by CD19-expressing B cells, which in turn activates T cells. Graphic C highlights the production of pro-inflammatory mediators, such as cytokines and chemokines, and the release of matrix metalloproteinases, or MMPs.

1011

In contrast, the expression of CD20, another cell surface molecule expressed on B cells, is lost as B cells differentiate into plasmablasts and plasma cells. As a result, existing therapies targeting CD20 do not directly target plasmablasts and plasma cells. The graphic below illustrates CD19’s broad expression as compared to CD20’s lack of expression as cells differentiate into plasmablasts and plasma cells.

Inebilizumab is a humanized, affinity-optimized, afucosylated immunoglobulin G1 kappa mAb that binds to CD19. The Fc portion of inebilizumab will recruit natural killer cells or macrophages, which deplete the CD19-expressing B cells through ADCC and ADCP. The depletion of CD19-expressing B cells may result in a reduction of autoantibodies, decreased antigen presentation and reduced pro- inflammatory mediators. In addition, the removal of fucose from the Fc results in approximately tenfold increased affinity to the Fc receptors and significantly enhances ADCC and ADCP. The antigen-binding properties of inebilizumab, including high affinity and slow internalization, are favorable for ADCC and ADCP-dependent mechanisms of action.

Background and Unmet Need

NMOSD

NMOSD is a unifying term for neuromyelitis optica, previously known as Devic’s disease, and related syndromes. NMOSD is a rare, severe, relapsing, neuroinflammatory autoimmune disease that attacks the optic nerve, spinal cord and brain stem, and often leads to irreversible blindness and paralysis. AQP4+ patients are thought to represent approximately 80% of the NMOSD patient population. These AQP4-IgG autoantibodies, produced by plasmablasts and plasma cells, bind primarily to astrocytes in the central nervous system. Binding of AQP4-IgG antibodies to central nervous system cells is believed to trigger attacks, which can damage the optic nerve, spinal cord and brain stem. Loss of vision, paralysis, loss of sensation, bladder and bowel dysfunction, nerve pain and respiratory failure can all be manifestations of the disease. Each NMOSD attack leads to further damage and disability. NMOSD occurs more commonly in women and it may be more common in individuals of African and Asian descent. Currently, patients are treated with immunosuppressants, steroids and off-label use of rituximab in an effort to prevent NMOSD attacks. Patients experiencing an attack are treated with steroids, intravenous immunoglobulin, or IVIG, and plasmapheresis. However, these treatments are known to cause adverse events that may lead to treatment discontinuation, and the benefits and risks of these off-label treatments in NMOSD remain uncertain. In June 2019, eculizumab from Alexion Pharmaceuticals, Inc. received FDA approval for the treatment of adults with NMOSD who are anti-AQP4 antibody positive. In August 2020, satralizumab from Genentech, Inc. received FDA approval for the treatment of adults with NMOSD who are anti-AQP4 antibody positive.

We estimate the prevalence of NMOSD to be approximately 1 to 5 per 100,000 in the United States, with an estimated 10,000 patients suffering from NMOSD as of 2016. In Japan, the prevalence of NMOSD was approximately 4.1 per 100,000, and we estimate that there were 5,000 patients suffering from the disease as of 2017. In several European countries, the prevalence of NMOSD was estimated to range from less than 1 to 7 per 100,000, and we estimate a patient population of approximately 8,000 as of 2013.

Other Potential Diseases

We are also pursuing the following additional diseases associated with CD19-expressing B cells for potential treatment with inebilizumab:

Desensitization of highly sensitized candidates for kidney transplant. Patients with high levels of alloantibodies waiting for a kidney transplant have a lower chance of getting a matching organ and overall worse clinical outcomes following transplant. Approximately 6.5% of the estimated 95,000 patients on the waiting list for a kidney transplant in the United States are considered “sensitized” with a calculated panel-reactive antibodies score of 98% to 100%. We ~~plan~~are toexploring ~~explore~~ the potential of inebilizumab, used alone or in combination with VIB4920, to reduce levels of alloantibodies in kidney transplant candidates in a proof of concept study. In 2019, we initiated screening of patients for a Phase 2 trial.

Myasthenia gravis. Myasthenia gravis is a neuromuscular disorder caused by autoantibodies against the acetylcholine receptor, muscle specific kinase or other acetylcholine receptor-related proteins in the post-synaptic muscle membrane. Its prevalence is estimated to be 20 per 100,000 in the United States, and based on this prevalence, we 12

11Myasthenia gravis. Myasthenia gravis is a neuromuscular disorder caused by autoantibodies against the acetylcholine receptor, muscle specific kinase or other acetylcholine receptor-related proteins in the post-synaptic muscle membrane. Its prevalence is estimated to be 20 per 100,000 in the United States, and based on this prevalence, we estimate the patient population to be approximately 56,000. The underlying pathogenesis has a high degree of similarity to NMOSD in that autoantibodies secreted by plasmablasts and/or plasma cells play a key role and are thought to be directly pathogenic. Patients with myasthenia gravis are currently managed with off-label immunosuppressants or steroids, or with one recently approved treatment. We initiated a Phase 3 trial of inebilizumab for myasthenia gravis in 2020

IgG4-related disease. This is a group of disorders marked by tumor-like swelling and fibrosis of affected organs, which may be caused by infiltration of CD19-expressing plasma cells that generate IgG4 antibodies. The clinical presentation is heterogeneous, and a variety of organs can be affected, including the pancreas, salivary glands, retroperitoneum and kidneys. Patients with this disorder have increased levels of IgG4, and IgG4 levels tend to correlate with disease activity. The prevalence is not well defined. A small trial of rituximab has suggested clinical benefits of B cell depletion in this disease. We are preparing to study the potential of inebilizumab in the treatment of IgG4-related disease. We have submitted an IND for inebilizumab in IgG4-related diseases in 2020, and aim to initiate a Phase 2b trial in mid-year 2020.

Clinical Development

In May 2019, we announced detailed results from the N-MOmentum trial, our pivotal clinical trial for inebilizumab and the largest controlled trial ever conducted in NMOSD. The N-MOmentum trial was a global, randomized, double-blind, placebo-controlled trial with an open-label extension period, evaluating the safety and efficacy of inebilizumab in adult patients with NMOSD. Key inclusion criteria were adult patients with NMOSD and an Expanded Disability Status Scale score of ≤7.5 (8.0 with medical monitor approval) having either a history of at least one NMOSD attack requiring rescue therapy during the past year, or at least two attacks requiring rescue therapy during the two years before screening. AQP4-IgG seropositive and seronegative, AQP4+ and AQP4- patients were eligible for inclusion, with stratification based on serostatus. Eligible patients were randomized in a 3:1 ratio to receive intravenous doses of inebilizumab 300 mg or placebo, respectively, administered on days 1 and 15. Patients received oral corticosteroid (prednisone 20 mg/day or equivalent) between days 1 and 14, tapered to day 21, to minimize risk of an attack while the pharmacological action of inebilizumab took effect. The randomized period for each patient was for a maximum of 197 days, or until occurrence of an adjudicated attack. The trial was designed to enroll patients until the earlier of the occurrence of 67 adjudicated NMOSD attacks or the randomization and dosing of 252 patients. Based on a recommendation of the Independent Data Monitoring Committee, or IDMC, for the trial, enrollment was stopped at 231 patients and 43 adjudicated NMOSD attacks. Based on the results observed, the IDMC determined that exposing patients to the risk of placebo was no longer justified. All patients continued in a safety follow-up period for 12 months after administration of their last dose of inebilizumab. Patients completing the randomized controlled period were given the option to enter into an open-label extension of the trial in which all patients received inebilizumab every six months. The open-label extension isconcluded ~~ongoing~~in Q4 2020.

The primary endpoint was time from treatment initiation to occurrence of an NMOSD attack during the randomized controlled period. NMOSD attack diagnosis was standardized using 18 clinically meaningful criteria that were developed for the trial in consultation with the FDA and leading experts. Each attack was adjudicated by an independent blinded panel of experts in the treatment of NMOSD. The trial met the primary endpoint, with a statistically significant difference in the time to NMOSD attack in favor of inebilizumab over placebo. In the AQP4+ population, 11.2% (18/161) of the patients receiving inebilizumab had an attack, compared to 42.3% (22/52) of patients receiving placebo, representing a 77.3% risk reduction. In the intent-to-treat, or ITT, population which also included AQP4- patients, 12.1% (21/174) of the patients receiving inebilizumab had an attack, compared to 39.3% (22/56) of patients receiving placebo, representing a 72.8% risk reduction, as shown in the table below.

The trial enrolled a small number of AQP4- patients (n = 17), and very few attacks were observed in this population. As a result, no clear conclusions can be drawn with respect to the AQP4- population.

The Kaplan-Mejer graphics below illustrate the probability of a patient being NMOSD attack-free during the course of the N-MOmentum randomized control period in AQP4-IgG seropositive patients and the ITT patient populations.

We also evaluated the following four secondary endpoints in the N-MOmentum randomized control period: worsening of the Expanded Disability Status Scale, or EDSS, score from baseline; change from baseline in low-contrast visual acuity binocular score (by low-contrast Landolt C Broken Ring Chart, or LCVNB); cumulative total number of new MRI lesions and the number of NMOSD-related inpatient hospitalizations (longer than an overnight stay). These endpoints were assessed at the last visit of each patient during the randomized controlled period. The trial met three of the four secondary endpoints with statistical significance, as illustrated in the table below.

Compared to patients who received placebo, we observed that a significantly smaller proportion of patients experienced a worsening from baseline of their EDSS score when treated with inebilizumab. Of patients treated with inebilizumab, 15.5% (27/174) experienced a worsening from baseline of their EDSS score, compared to 33.9% (19/56) of patients who received placebo. We also observed a significant reduction in the number of NMOSD-related inpatient hospitalizations for patients treated with inebilizumab compared to patients who received placebo (p = 0.01; rate ratio 0.286). In addition, the cumulative new MRI lesion count was significantly lower in patients treated with inebilizumab (79/174) compared to patients who received placebo (32/56) (p = 0.0034; rate ratio 0.566). We did not observe a significant difference in the change from baseline in low-contrast visual acuity binocular score between the inebilizumab and placebo groups.

Inebilizumab effectively depleted peripheral B cells within four weeks to below 10% of the average baseline in the N-MOmentum randomized control period, as illustrated below. The mean B cell count did not rise above this threshold throughout the 197-day randomized controlled period of the trial.

Inebilizumab was generally well-tolerated in the randomized control period and the rates and types of treatment-emergent adverse events, or TEAEs, reported in patients receiving inebilizumab were broadly similar to TEAEs reported by patients receiving placebo, as illustrated below. Adverse events were reported in 71.8% (125/174) of the patients receiving inebilizumab and in 73.2% (41/56) of the patients receiving placebo in the randomized control period. Urinary tract infection, arthralgia, back pain, headache, fall, hypoesthesia, cystitis and eye pain were nominally more frequent in patients receiving inebilizumab. The incidence of serious adverse events, or SAEs, was 4.6% in patients receiving inebilizumab and 8.9% in patients receiving placebo during the randomized control period. No specific SAEs were reported in more than one patient and no deaths occurred throughout the randomized controlled period. Two deaths have been reported in the ongoing open-label period. One death occurred in a patient experiencing a myelitis attack and was considered unrelated to inebilizumab by the investigator. The second death was due to complications from mechanical ventilator-associated pneumonia in a patient who developed new neurological symptoms and seizures, the cause of which could not be definitively established. The possibility that the death was treatment-related could not be ruled out, and as a result, under the terms of the protocol for the trial, the death was assessed as treatment-related. The differential diagnosis

The ongoing open-label phase of the N-MOmentum is designed to evaluate the longer-term efficacy and safety of inebilizumab. In the interim open-label extension safety data presented in September 2019, with a safety data cut-off of June 6, 2019, inebilizumab remained generally well-tolerated with the types of TEAEs consistent with that observed during the randomized control period. For patients who received at least one dose of inebilizumab during the combined period of both the randomized control period and the open-label extension through June 6, 2019, the incidence of SAEs after receiving inebilizumab was 16.0%. As discussed above, two deaths have been reported in the open-label period. As of June 6, 2019, adverse events occurring in greater than 10% of patients who received at least one dose of inebilizumab during the combined period of both the randomized control period and the open-label extension were UTI (22.2%), nasopharyngitis (16.4%), back pain (12.4%), infusion related reaction, or IRR (12.4%), arthralgia (11.6%) and headache (11.1%) after receiving inebilizumab.

Based on the positive results of the N-MOmentum trial, we submitted a BLA to the FDA in June 2019, which the FDA accepted for review in August 2019. The FDA set a PDUFA date of June 11, 2020.

Based on the positive results of the N-MOmentum trial, we submitted a BLA to the FDA in June 2019, which the FDA accepted for review in August 2019. On June 11, 2020, the FDA approved Uplizna® (inebilizumab-cdon) for the treatment of adult patients with NMOSD who are anti-AQP4 antibody positive as a twice-a-year maintenance regimen following initial doses. We commercially launched Uplizna® following FDA approval in June 2020.

In the interim open-label extension data presented in July 2020 to support Japan PMDA submission, with a data cut-off of February 28, 2020, inebilizumab remained generally well-tolerated with the types of TEAEs consistent with that observed during the randomized control period. For patients who received at least one dose of inebilizumab during the combined period of both the randomized control period and the open-label extension through February 28, 2020, the incidence of SAEs after receiving inebilizumab was 19.6%. As discussed above, two deaths have been reported in the open-label period. As of February 28, 2020, adverse events occurring in greater than 10% of patients who received at least one dose of inebilizumab during the combined period of both the randomized control period and the open-label extension were UTI (25.8%), nasopharyngitis (19.6%), arthralgia (14.7%), upper respiratory tract infection (14.2%) and headache (14.2%), back pain (13.3%), and infusion related reaction, or IRR (12.4%) after receiving inebilizumab.

VIB4920

VIB4920 is a fusion protein designed to bind to CD40L on activated T cells, blocking CD40L from interacting with CD40-expressing B cells and other binding partners. This is intended to prevent B cells from differentiating into plasma cells and memory B cells. Blocking CD40L can also inhibit stimulation of dendritic cells and monocytes by T cells, which reduces production of pro-inflammatory mediators. We believe that these combined effects produce powerful immunomodulation targeting of both T and B cell driven diseases.

Two Phase 1 clinical trials of VIB4920 have been completed to date: a Phase 1a single-ascending dose trial in healthy volunteers and a Phase 1b multiple-ascending dose trial in patients with rheumatoid arthritis, a disease with well understood clinical endpoints enabling proof of clinical activity in a relatively small clinical trial. In both trials, VIB4920 was generally well-tolerated, with no evidence of platelet aggregation that can lead to thromboembolic side effects observed with an earlier generation CD40L mAb. In the Phase 1b trial, VIB4920 decreased disease activity in patients with active rheumatoid arthritis, and the majority of patients achieved low level disease activity or remission at the two highest dose levels. We believe that the dose-dependent reduction in autoantibody levels coupled with the clinical activity observed in rheumatoid arthritis suggest that VIB4920 effectively blocks the CD40/CD40L interaction. A Phase 2b trial in Sjögren’s syndrome, which is designed as Phase 3-enabling, is ongoing and in 2019, we initiated a separate Phase 2 trial in kidney transplant rejection. Both of these diseases are associated with the CD40/CD40L co-stimulatory pathway, and we also plan to initiate additional studies in other diseases associated with the same pathway in 2020.

A Phase 2b trial in Sjögren’s syndrome, which is designed as Phase 3-enabling, is ongoing and in 2019, we initiated a separate Phase 2 trial in kidney transplant rejection. Both of these diseases are associated with the CD40/CD40L co-stimulatory pathway. Furthermore, a Phase 2 trial of VIB4920 in rheumatoid arthritis is ongoing.

Mechanism of Action

The CD40/CD40L interaction plays a critical role in driving humoral immune responses and has been implicated in the pathogenesis of several autoimmune diseases, including Sjögren’s syndrome, as well as other conditions such as kidney transplant rejection. CD40 is constitutively expressed on a variety of antigen presenting cells, including B cells, dendritic cells and macrophages. CD40L is highly regulated and predominately expressed on activated T cells. CD40/CD40L interactions between B cells and activated T cells are essential for mounting effective humoral responses to T cell dependent antigens. The binding of VIB4920 to both soluble CD40L and CD40L expressed on the surface of activated T cells is intended to block CD40L from interacting with CD40-expressing B cells and other binding partners, preventing B cells from differentiating into plasma cells and memory B cells. Each of the graphics below illustrates different elements of the CD40/CD40L co-stimulatory pathway that VIB4920 is designed to inhibit. CD40 signaling is required for germinal center formation, somatic hypermutation and the generation of memory B cells and long-lived plasma cells, as illustrated in graphic A below. Engagement of CD40 on macrophages and dendritic cells leads to activation of these cells with ensuing production of pro-inflammatory mediators, including cytokines, chemokines and MMPs, and upregulation of other co-stimulatory pathways, as illustrated in graphics B and C below.

1819

The potential benefits of targeting the CD40L/CD40 interaction in autoimmune diseases such as lupus nephritis and ITP have been suggested by previous clinical trials conducted by other companies using full antibodies directed at CD40L. However, the earlier generation CD40L mAb caused adverse thromboembolic side effects related to platelet aggregation due to crosslinking of anti-CD40L antibodies co-bound to platelet CD40L and FcgRIIa on adjacent platelets. To avoid complications associated with mAb-based targeting of CD40L, VIB4920 was designed as a novel CD40L binding protein comprised of two Tn3 proteins fused to human serum albumin. Tn3 is a small protein scaffold that does not possess an Fc domain and therefore is unlikely to induce adverse platelet responses.

Background and Unmet Medical Need for Sjögren’s Syndrome and Kidney Transplant Rejection

We are initially developing VIB4920 in parallel in two diseases: Sjögren’s syndrome and kidney transplant rejection. Sjögren’s syndrome is a chronic, systemic autoimmune disease characterized by lymphocytic infiltration of the exocrine glands such as the lacrimal and salivary glands. The disease frequently leads to keratoconjunctivitis sicca (dry eye) and xerostomia (dry mouth). Sjögren’s syndrome may occur with other autoimmune diseases, such as SLE or rheumatoid arthritis. Sjögren’s syndrome is estimated to affect 0.5% to 1.0% of the population, with an estimated one million people in the United States suffering from Sjögren’s syndrome. No treatments have been shown to alter the course of this disease. Supportive treatment is aimed at relieving dry mouth/dry eye symptoms.

Current regimens used to prevent rejection following kidney transplant commonly rely on a combination of CD28/B7 pathway blockade with belatacept and calcineurin inhibitors. While generally effective, these regimens are associated with slow deterioration of kidney function as a result of calcineurin inhibitor toxicity. Literature and data from animal models support the hypothesis that blockage of the CD40/CD40L pathway may be effective in the prevention of transplant rejection. We plan to conduct a proof of concept study to test the hypothesis that VIB4920, when combined with belatacept, will result in similar or reduced rates of kidney transplant rejection in comparison to current calcineurin based regimens while avoiding the renal toxicity associated with calineurin inhibitors.

Clinical Development

We initiated a Phase 2 trial in kidney transplant rejection in 2019 and a separate Phase 2b trial in Sjögren’s syndrome is ongoing, the latter of which is designed to be Phase 3-enabling. Both of these conditions are associated with immune overactivation through the CD40/CD40L co-stimulatory pathway. Furthermore, ~~and~~a wePhase ~~plan~~2 totrial ~~initiate~~of ~~additional~~VIB4920 ~~studies~~ in ~~other~~rheumatoid ~~diseases~~arthritis ~~associated~~is ~~with the same pathway in 2020~~ongoing.

Phase 1b Trial

In August 2018, we completed a Phase 1b, randomized, double-blinded, placebo-controlled trial conducted in patients with rheumatoid arthritis, a disease with well understood clinical endpoints enabling proof of clinical activity in a relatively small clinical trial. Fifty-seven patients enrolled in the trial and were randomized into four sequential VIB4920 dose cohorts, with doses ranging from 75 mg to 1500 mg, or treated with placebo, given by intravenous infusion every other week for 12 weeks, followed by 12 weeks of post-treatment observation. All patients received a systemic immunosuppressant, methotrexate, or a disease-modifying antirheumatic drug as background therapy.

1920

The primary endpoint of the Phase 1b trial was the safety and tolerability of VIB4920. Consistent with the Phase 1a trial, VIB4920 was generally well-tolerated in patients with rheumatoid arthritis, with diarrhea, hyperhidrosis, upper respiratory tract infection and urinary tract infection being the most common TEAEs reported. We observed a balanced distribution of TEAEs between placebo and the four treatment groups, as shown in the table below. No thromboembolic events or clinically significant coagulation lab abnormalities were observed. One life-threatening treatment-emergent serious adverse event occurred, which was determined to be unrelated to VIB4920.

In addition to safety and tolerability, clinical benefit with VIB4920 in patients with rheumatoid arthritis was also evaluated. Key secondary and exploratory endpoints in the multiple ascending dose study in rheumatoid arthritis measured at week 12 included change in disease activity, as measured by changes from baseline in DAS28-CRP score, as well as biomarkers such as rheumatoid factor, or RF, autoantibodies, serum C-reactive protein, or CRP, and Vectra-DA score.

DAS28-CRP is a composite clinical disease activity scale used in assessing the disease activity score of rheumatoid arthritis which takes into account the number of swollen and tender joints, CRP levels and a patient global health assessment. In this trial, VIB4920 reduced disease activity quantified by DAS28-CRP score at the two highest doses, as shown in the graphic below. At week 12, the adjusted mean change from baseline of DAS28-CRP (standard error) was: -2.3 (0.3) in the VIB4920 1500 mg group, -2.2 (0.3) in the VIB4920 1000 mg group, -1.2 (0.3) in the VIB4920 500 mg group, 0.1 (0.4) in the VIB4920 75 mg group and -1.0 (0.3) in the placebo group. The effect of VIB4920 on DAS28-CRP was rapid, with reductions evident by day 15, after only a single dose of VIB4920. The reduction of disease activity as compared with placebo was both clinically and statistically meaningful in the groups receiving the highest two doses of VIB4920. Seventy-five percent of patients in the 1500 mg group and 50% of patients in the 1000 mg group achieved a DAS28-CRP score of 3.2 or less at week 12 indicating they achieved low disease activity or clinical remission in the trial, compared to 6.7% of the patients who received placebo.

RFs are a family of autoantibodies produced against the Fc portion of IgG which are elevated in rheumatoid arthritis and are associated with poor prognosis. VIB4920 reduced RF titers at the 500, 1000 and 1500 mg dose levels. Reductions in RF titers from baseline were evident in response to VIB4920 as early as day 29, with the 1500 mg dose reducing RF titers by approximately 50% by day 85.

Vectra DA is a commercially available and validated biomarker panel which measures 12 biomarkers (adhesion molecules, growth factors, cytokines, matrix metalloproteinases, skeletal proteins, hormones, and acute phase proteins) and combines these parameters into a single score to assess the key mechanisms and pathways that drive rheumatoid arthritis disease activity. At day 85, Vectra DA multi-biomarker score was reduced in patients at the 1000 and 1500 mg VIB4920 dose levels (p = 0.018 and p = 0.001, respectively). The results of this clinical trial were published in a featured cover article in Science Translational Medicine.

In summary, VIB4920 decreased disease activity in patients with active rheumatoid arthritis, with at least 50% and 75% of patients, respectively, achieving low disease activity or clinical remission in the two highest dose groups at Day 85. We believe that the observed dose-dependent decrease in autoantibody levels, together with the inhibition of T cell dependent antibody responses in healthy volunteers, as reported in our Phase 1a trial of VIB4920, suggests that VIB4920 may effectively block the CD40/CD40L interaction.

Phase 1a Trial

In May 2016, a Phase 1a, randomized, double-blinded, placebo-controlled, single-ascending dose trial was completed to evaluate the safety and tolerability of VIB4920 in healthy adults. Fifty-nine patients enrolled in the trial and were randomized into seven active treatment cohorts, with doses ranging from 3 mg to 3000 mg, or treated with placebo. The primary endpoint of the Phase 1a trial was to measure the incidence of TEAEs and TESAEs. VIB4920 was generally well-tolerated, with the most common TEAEs being nasopharyngitis, headache and diarrhea, and no TESAEs were observed.

VIB4920 also demonstrated dose-dependent inhibition of T cell dependent antibody responses. In order to evaluate the ability of VIB4920 to influence humoral immune responses in healthy patients, the Phase 1a trial measured inhibition of an induced T cell dependent IgG antibody response to the neoantigen keyhole limpet hemocyanin, or KLH. We observed a 78% and 86% reduction in anti-KLH IgG antibody concentration in the VIB4920 1000 mg and 3000 mg cohorts, respectively, compared to placebo at day 43. In the highest VIB4920 dose group, 7 of 8 patients had undetectable titers of anti-KLH-IgG at day 43, suggesting near complete suppression of the humoral immune response by VIB4920. These data highlight the mechanism of action of VIB4920 and demonstrate its potential to suppress B cell activation and plasma cell differentiation.

VIB7734

VIB7734 is a humanized mAb intended to be a novel treatment for autoimmune diseases where the pathology is driven principally by overproduction of type I interferons and other cytokines secreted by pDCs. VIB7734 is designed to target and bind to ILT7, a cell surface molecule specific to pDCs, leading to pDC depletion. pDCs generate the majority of type I interferons in pathological states. The depletion of pDCs may also decrease other inflammatory cytokines such as TNF-a and IL-6, which are critical to the pathogenesis of a number of autoimmune diseases. We have completed a Phase 1a single-ascending dose trial in patients with any one of the following six different autoimmune diseases: CLE, SLE, Sjögren’s syndrome, systemic sclerosis, polymyositis and dermatomyositis. The Phase 1a trial demonstrated that VIB7734 was generally well-tolerated and reduced pDC numbers in peripheral blood. ~~Our~~In ~~ongoing~~November 2020, we reported the final data from our Phase 1b ~~multiple~~trial ~~ascending~~with ~~dose~~VIB7734 in an oral presentation at the American College of Rheumatology Convergence 2020. In this trial, ~~includes~~treatment with VIB7734 was shown to potently deplete pDCs, both in blood and in CLE skin lesions. Most patients experienced a ~~cohort~~clinically significant reduction in the extent and severity of ~~patients~~skin lesions, as measured by CLASI scores, following treatment with VIB7734.

Mechanism of Action

In certain autoimmune diseases, once pDCs are activated, they secrete large amounts of cytokines, including type I interferons, as illustrated in graphic A below. pDC infiltration and the resulting accumulation in tissues has been observed in a number of autoimmune diseases and appears to correlate with disease activity. Additionally, pDCs are involved in antigen presentation to T cells leading to the activation of autoreactive T cells, as illustrated in graphic B below. VIB7734 is a human IgG1 lambda afucosylated mAb specific for ILT7, a cell surface molecule expressed only on pDCs. VIB7734 binds to ILT7 on the surface of pDCs, which leads to recruitment of macrophages and natural killer cells, thus inducing apoptosis and depletion of pDCs in vivo. The afucosylation of VIB7734 is designed to enhance the potency of VIB7734 for antibody-dependent cell-mediated cytotoxicity against pDCs. We believe that depletion of pDCs will not only reduce type I interferons, but also other types of cytokines and mediators involved in a number of autoimmune diseases. Each of the graphics below illustrates different elements of the function of pDCs that VIB7734 is designed to deplete, with graphic A showing the production of pro-inflammatory cytokines and graphic B highlighting the antigen presenting process by pDCs to T cells.

Background and Market Opportunity in Selected Autoimmune Diseases

VIB7734 has potential utility across multiple autoimmune diseases that are characterized by elevated type I interferon signatures. These include CLE, SLE, Sjögren’s syndrome, systemic sclerosis, polymyositis, dermatomyositis and a subset of rheumatoid arthritis. The majority of these conditions can lead to significant morbidity and currently have no approved treatments.

Overexpression of type I interferons is consistently found in the majority of patients with SLE, a systemic autoimmune disease that is characterized by the presence of a variety of autoantibodies and can involve multiple organs, including the skin, joints, kidneys and central nervous system. The estimated number of people suffering from SLE in the United States was approximately 161,000 to 322,000 in 2011. Based on this, we estimate the prevalence of SLE in the United States to range between 49 to 100 per 100,000 individuals. Treatment of SLE still largely relies on corticosteroids and non-specific immunosuppressive drugs.

Infiltration of inflamed muscle tissue and overexpression of type I interferons have also been found in inflammatory myopathies, a group of conditions associated with inflammation of the muscles with resulting muscle weakness. We estimate that a subset of this group of myopathies, polymyositis and dermatomyositis, has a prevalence of approximately 5 to 22 per 100,000 individuals in the United States, and based on this prevalence, we estimate the patient population to be approximately 16,000 to 70,000. Treatment of inflammatory myopathies typically involves corticosteroids and nonspecific immunosuppressive drugs.

2223

Systemic sclerosis is a chronic autoimmune disease associated with thickening and fibrosis of the skin, frequently also involving other organ systems such as the lungs, heart and kidneys. The prevalence of systemic sclerosis is estimated to be between 13.5 and 44.3 per 100,000 individuals in Europe and North America, and based on this prevalence, we estimate the patient population to be approximately 300,000. No treatments that alter the course of this disease are currently available, and patients are managed with supportive treatment for the various organ manifestations of this disease.

Sjögren’s syndrome is an autoimmune condition involving inflammation and destruction of the salivary and lacrimal glands. Other organs such as joints, lungs and kidneys may be involved as well. Sjögren’s syndrome is estimated to have affected between 53,000 and 248,000 people in the United States in 2017. No treatments have been shown to alter the course of this disease.

Rheumatoid arthritis is a chronic autoimmune disease involving progressive inflammation and destruction of the joints. A subset of approximately 33% of patients with rheumatoid arthritis has been shown to have elevated expression of interferon regulated genes. This subgroup also appears to have a poorer response to rituximab treatment.

Clinical Development

Ongoing Phase 1b Trial

In December 2018, we initiated a multiple ascending dose Phase 1b trial to evaluate the safety and tolerability of multiple subcutaneous doses of VIB7734 in a cohort of patients with any one of the following six different autoimmune diseases: CLE, SLE, Sjögren’s syndrome, systemic sclerosis, polymyositis and dermatomyositis.

Phase 1a Trial

In a completed Phase 1a trial, the safety, PK, pharmacodynamics, or PD, and immunogenicity of single subcutaneous doses of VIB7734 were evaluated in patients with any one of the following six different autoimmune diseases: CLE, SLE, Sjögren’s syndrome, systemic sclerosis, polymyositis and dermatomyositis. A total of 36 patients were enrolled and randomized across five cohorts to receive a single subcutaneous dose of VIB7734 or matching placebo, of which ten patients received placebo treatment.

VIB7734 was generally well-tolerated. Sixty-nine percent (18/26) of the patients treated with VIB7734 experienced at least one TEAE, with a majority of such TEAEs characterized as non-serious and deemed not related to VIB7734. The most frequent TEAEs in the patients treated with VIB7734 were infections, musculoskeletal and connective tissue disorders, and gastrointestinal disorders. No VIB7734-related TESAEs were observed. The rates and types of TEAEs reported in patients receiving VIB7734 were broadly similar to TEAEs reported by patients receiving placebo.

After a single subcutaneous injection, drug exposure and pDC levels were measured periodically during the 85-day follow-up period. VIB7734 peak concentrations were observed 5 to 8 days post dose and levels increased in a dose-dependent manner. Increasing doses were associated with a non-linear reduction in pDCs. Median reduction of pDC levels by 57% was seen at the lowest dose of 1 mg, with median reductions of 90% observed in higher doses. Time to recovery of pDC levels appeared to be dose dependent.

Pre-clinical Programs

We are also conducting pre-clinical research and development on two other product candidates. The first candidate, VIB1116, is a mAb designed to decrease the number and function of antigen-presenting dendritic cells. We ~~expect~~completed ~~to conduct~~ pre-clinical toxicology studies inand ~~the~~submitted ~~first half of 2020 to enable a submission of~~ an IND application in Q4 2020. The second candidate is a mAb cytokine fusion protein designed to inhibit inflammatory responses. We are currently conducting pre-clinical efficacy studies of this candidate in animal models.

Medical Affairs and Patient Advocacy

We ~~are~~built ~~building~~ a medical affairs team that ~~will~~is be engaged in furthering awareness of autoimmune disease and education of clinicians with respect to the clinical knowledge we have gained from our clinical trials. Our medical affairs team ~~will~~ also ~~support~~supports investigator sponsored trials and research collaborations. Our patient advocacy team ~~will~~focuses ~~focus~~ on expanding our relationships with the patient advocacy community for NMOSD and for other autoimmune diseases.

Commercial Opportunity and Commercialization Plan for Inebilizumab

The commercial opportunity for ~~inebilizumab~~Uplizna®, as ~~potentially~~ the first FDA-approved monotherapy for the treatment of patients with NMOSD with one or more attacks, stems from its distinctive value proposition. We believe ~~inebilizumab~~Uplizna® has the potential for disease modification by preventing the next NMOSD attack through depletion of B cells and plasma cells. In addition, pivotal clinical trial data suggests that ~~inebilizumab~~Uplizna® reduces the worsening of disability, hospitalizations and new MRI lesions.

NMOSD is a rare, devastating condition that attacks the optic nerve, spinal cord and brain stem and often leads to irreversible blindness and paralysis. Patients with NMOSD are diagnosed by multiple physician specialties including ophthalmologists or neurologists once they suffer their first attack.

Highly specific serum autoantibodies, AQP4-IgG, are thought to be present in about 80% of patients and are likely pathogenic. AQP4 autoantibodies induce central nervous system damage through complement activation and antibody-mediated cytotoxicity. Since 2006, the presence of AQP4-IgG has been included as part of the NMOSD diagnostic criteria. However, it is noteworthy, that a patient can still be deemed a NMOSD patient even if no AQP4-IgG is present as long as other NMOSD definition criteria are met.

We have identified first-line newly diagnosed adult patients with NMOSD who are anti-AQP4 antibody positive and such patients with NMOSD that are unstable as our initial target population for ~~inebilizumab, if approved by the FDA and assuming these patient populations are within the approved patient population~~Uplizna®. Patients with NMOSD are considered unstable if they are on an unapproved therapy and are at risk of suffering another attack based on physician assessment of severity and frequency of recent attacks. The majority of our initial target population are treated by NMOSD specialists, multiple sclerosis specialists and community neurologists. We estimate that NMOSD affects approximately 10,000 patients in the United States with approximately 70% of patients treated in a small number of medical centers of excellence. We ~~plan~~are to initially ~~commercialize~~commercializing ~~inebilizumab~~Uplizna® in the United States with a specialty clinical sales force of fewer than 30 individuals focused on the highest prescribers, which we believe is fewer than 300 physicians.

Our ~~pre-launch~~ commercial activities ~~are~~ focused on delivering comprehensive disease awareness and education to NMOSD specialists, multiple sclerosis specialists and community neurologists. These disease education efforts will communicate the importance of CD19-expressing B cells and plasma cells in producing autoantibodies, which leads to NMOSD. We believe the broad understanding of this evidence will help to establish ~~inebilizumab~~Uplizna® as a first-line treatment in patients with NMOSD and support our launch uptake following FDA approval~~, if achieved~~. Over time we intend to address the stable NMOSD patient population who have not suffered a recent attack and are treated with an unapproved therapy, given the disease modification potential of inebilizumab. We believe the improved EDSS score, reduction in MRI lesions and reduction in hospitalization will be meaningful to patients. Furthermore, we believe the potential semi-annual maintenance dosing after the two initial doses on days 1 and 15 can improve patient quality of life.

We have conducted market research with physicians and payors to forecast the potential commercial opportunity for ~~inebilizumab~~Uplizna® in the United States. We have also completed preliminary health economic analyses of the potential direct cost savings that ~~inebilizumab~~Uplizna® may be able to provide to the healthcare system and have completed multiple surveys with payors to evaluate the potential coverage for ~~inebilizumab~~Uplizna® by health insurers. Health insurers surveyed have indicated that their perception of the likelihood of ~~inebilizumab~~Uplizna® coverage is influenced by the lack of FDA-approved first-line monotherapy treatments and the potential for ~~inebilizumab~~Uplizna® to provide significant direct cost savings based on its potential to prevent the next attack for patients with NMOSD. Based on these analyses, we believe that the pricing for inebilizumab can be supported above the current pricing for other unapproved therapies for treating NMOSD. We estimate that approximately 50% to 65% of our target patient population is commercially-insured and may be eligible for co-pay assistance programs to help them access inebilizumab.

To address markets outside of the United States, we plan to seek one or more partners with international sales expertise who can sell inebilizumab in target markets. We anticipate that in certain markets additional clinical trials of inebilizumab may be required to obtain regulatory approval and/or ensure market access. We have formed a collaboration partnership with Hansoh Pharma for co-development and commercialization of inebilizumab in patients with NMOSD and other autoimmune diseases and hematological cancers in China, Hong Kong and Macau and we are continuing to evaluate potential partnerships to pursue regulatory approval and commercialization of inebilizumab in NMOSD in other geographic regions. See “—Licenses and Strategic Agreements—Hansoh License and Collaboration Agreement”. In addition, we have formed a collaboration partnership with MTPC for co-development and commercialization of inebilizumab in Japan, Thailand, South Korea, Indonesia, Vietnam, Malaysia, Philippines, Singapore, and Taiwan for NMOSD as well as other indications that we and MTPC mutually agree to add to the MTPC License Agreement. See “—Licenses and Strategic Agreements—MTPC Agreement”.

Competition

The biotechnology and pharmaceutical industries are characterized by rapid technological advancement, significant competition and an emphasis on intellectual property. We face potential competition from many different sources, including major and specialty pharmaceutical and biotechnology companies, academic research institutions, governmental agencies and public and private research institutions. Any product candidates that we successfully develop and commercialize will compete with current therapies and new therapies that may become available in the future. We believe that the key competitive factors affecting the success of any of our product candidates will include efficacy, safety profile, dosing, cost, effectiveness of promotional support and intellectual property protection. With respect specifically to inebilizumab for patients with NMOSD, we expect the key competitive factors affecting the success of inebilizumab, if approved, will include the intended patient population (AQP4+ and AQP4- patients), the ability to use as a first-line therapy and as a monotherapy, the low frequency of dosing and administration and efficacy.

Inebilizumab for NMOSD

If inebilizumab is approved for the treatment of NMOSD, it will likely compete with two products that have achieved successful pivotal studies in NMOSD: Eculizumab from Alexion Pharmaceuticals, Inc., or Alexion, to be marketed as Soliris®, and satralizumab from Chugai Pharmaceutical Co., Ltd., or Chugai:

• In September 2018, Alexion reported positive pivotal data for Soliris® as an add-on therapy in patients with severe AQP4+ NMOSD. The trial, which was conducted in 143 patients, met its primary endpoint of time to first adjudicated on-trial relapse, demonstrating that treatment with Soliris® reduced the risk of NMOSD relapse by 94.2% compared to placebo (p < 0.0001). At 48 weeks, 97.9% of patients receiving Soliris® were free of relapse compared to 63.2% of patients receiving placebo. In addition, treatment with Soliris® reduced the adjudicated on-trial annualized relapse rate compared to placebo, a key secondary endpoint, by 95.5% (p<0.0001). With respect to its other secondary endpoints, including disability and quality of life measures, while the trial results favored Soliris®, the observed differences were small. Soliris® requires dosing every seven days for the first five weeks followed by dosing every 14 days thereafter. In June 2019, Alexion received FDA approval of Soliris® for the treatment of adults with NMOSD. Soliris has a boxed warning to alert health care professionals and patients that life-threatening and fatal meningococcal infections have occurred in patients treated with Soliris, and that such infections may become rapidly life-threatening or fatal if not recognized and treated early.

• In October 2018, Chugai reported positive pivotal data for satralizumab as an add-on therapy in patients with AQP4+ and AQP4- NMOSD. The trial was conducted outside of the United States and met its primary endpoint of time to first protocol-defined relapse in the double-blind period, demonstrating that treatment with satralizumab reduced the risk of NMOSD relapse by 62% compared to placebo (p = 0.0184; n = 83). The proportion of relapse free patients at weeks 48 and 96 was 88.9% and 77.6% with satralizumab and 66.0% and 58.7% with placebo, respectively. In patients with AQP4+ NMOSD only, satralizumab showed a 79% reduction of NMOSD relapse compared to placebo (hazard ratio = 0.21; n = 55). In AQP4+ patients only, the proportion of relapse free patients at weeks 48 and 96 was 91.5% and 91.5% with satralizumab and 59.9% and 53.3% with placebo, respectively. In patients with AQP4- NMOSD only, satralizumab showed a 34% reduction of NMOSD relapse compared to placebo, and the proportion of relapse free patients at weeks 48 and 96 was 84.4% and 56.3% with satralizumab, and 75.5% and 67.1% with placebo, respectively. In the trial, satralizumab was dosed subcutaneously at baseline and then at weeks two and four, followed by monthly subcutaneous dosing for 20 months. In December 2018, Chugai reported that satralizumab has met its primary endpoint as a monotherapy.

In addition, inebilizumab will likely compete with rituxumab, a monoclonal anti-CD20 antibody marketed by Genentech USA, Inc., as Rituxan®. Rituximab is an approved therapy for the treatment of adults with Non-Hodgkin’s Lymphoma, Chronic Lymphocytic Leukemia, rheumatoid arthritis and Granulomatosis and Microscopic Polyangiitis. While

~~not~~To ~~approved~~address ~~for~~markets outside of the ~~treatment~~United States, we plan to seek one or more partners with international sales expertise who can sell inebilizumab in target markets. We anticipate that in certain markets additional clinical trials of ~~NMOSD,~~Uplizna® ~~treatment~~may be required to obtain regulatory approval and/or ensure market access. We have formed a collaboration partnership with Hansoh Pharma for co-development and commercialization of Uplizna® in patients with NMOSD ~~with~~and ~~rituximab~~other ~~has~~autoimmune ~~been~~diseases ~~found~~and byhematological ~~clinicians~~cancers in China, Hong Kong and Macau and we are continuing to ~~reduce~~evaluate ~~the~~potential ~~frequency~~partnerships to pursue regulatory approval and commercialization of ~~relapses~~Uplizna® in NMOSD in other geographic regions.

In addition, Uplizna^®competes with rituxumab, a monoclonal anti-CD20 antibody marketed by Genentech USA, Inc., as Rituxan®. Rituximab is an approved therapy for the treatment of adults with Non-Hodgkin’s Lymphoma, Chronic Lymphocytic Leukemia, rheumatoid arthritis and Granulomatosis and Microscopic Polyangiitis. While not approved for the treatment of NMOSD, treatment of patients with NMOSD with rituximab has been found by clinicians to reduce the frequency of relapses of NMOSD.

VIB4920 and VIB7734

If VIB4920 is approved, it may compete with Belatacept (NULOJIX^®), a selective T cell co-stimulation blocker indicated for prophylaxis of organ rejection in adult patients receiving a kidney transplant that has been developed by Bristol-Myers Squib, as well as potential mAb drug candidates in development by UCB, Biogen, Boehringer Ingelheim, AbbVie and Novartis. If VIB7734 is approved, it may compete with drug candidates in development by Biogen and Boehringer Ingelheim.

All of our product candidates, if approved, may also compete with current treatments used for autoimmune disease, including various immunosuppressants and steroids.

Many of our competitors, either alone or with their collaboration partners, have significantly greater financial resources and expertise in research and development, pre-clinical testing, clinical trials, manufacturing, and marketing than we do. Future collaborations and mergers and acquisitions may result in further resource concentration among a smaller number of competitors.

Our commercial potential could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than products that we may develop. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market or make our development more complicated. These competitors may also vie for a similar pool of qualified scientific and management talent, sites and patient populations for clinical trials, as well as for technologies complementary to, or necessary for, our programs.

Supply and Manufacturing

We do not currently have the infrastructure or internal capability to manufacture our product candidates for use in clinical development and, if any product candidate is approved, commercialization. We rely, and expect to continue to rely, on third-party manufacturers for the production of our product candidates in compliance with cGMP requirements for use in clinical trials under the guidance of members of our organization. In the case of inebilizumab, we rely on AstraZeneca and we currently have no alternative manufacturer in place. Under our commercial supply agreement with AstraZeneca, AstraZeneca has agreed to provide us with a commercial supply of drug product for ~~inebilizumab~~Uplizna®. We believe that our existing stock of drug substance that has already been manufactured will be sufficient to supply us for approximately the first two years of the commercialization of ~~inebilizumab~~Uplizna® in the United States. See “—Licenses and Strategic Agreements—Clinical Supply Agreement with AstraZeneca UK Limited” and “—Licenses and Strategic Agreements—Commercial Supply Agreement with AstraZeneca UK Limited”.

We have built an internal team with significant technical, manufacturing, analytical, quality, regulatory, including cGMP, and project management experience to oversee our third-party manufacturers and to manage manufacturing and quality data and information for regulatory compliance purposes. We plan to continue to invest in process science, product characterization and supply chain improvements over time.

Intellectual Property

Our success depends in part on our ability to obtain and maintain proprietary protection for our product candidates, technology and know-how, to operate without infringing the proprietary rights of others and to prevent others from infringing our proprietary rights. Our policy is to seek to protect our proprietary position by, among other methods, pursuing and obtaining patent protection in the United States and in jurisdictions outside of the United States related to our proprietary technology, inventions, improvements and product candidates that are important to the development and implementation of our business. For example, we or our licensors have or are pursuing patents covering the composition of matter for each of our product candidates and we generally pursue patent protection covering methods-of-use for each clinical program. We also rely on trade secrets, know-how, continuing technological innovation and potential in-licensing opportunities to develop and maintain our proprietary position. Additionally, we expect to benefit, where appropriate, from statutory frameworks in the United States, Europe and other countries that provide a period of clinical data exclusivity to compensate for the time required for regulatory approval of our drug products.

We continually assess and refine our intellectual property strategy as we develop new technologies and product candidates. We plan to file additional patent applications based on our intellectual property strategies where appropriate, including where we seek to adapt to competition or to improve business opportunities. Further, we plan to file patent applications, as we consider appropriate under the circumstances, to protect new technologies that we develop.

The term of individual patents depends upon the laws of the countries in which they are obtained. In the countries in which we ~~currently~~seek file, the patent term is 20 years from the earliest date of filing of the first non-provisional patent application in a patent family, which may also serve as a priority application.

Legal frameworks are also available in certain other jurisdictions to extend the term of a patent. We currently intend to seek patent term extensions on any of our issued patents in any jurisdiction where we have a qualifying patent and the extension is available; however there is no guarantee that the applicable regulatory authorities, including the FDA in the United States, will agree with our assessment of whether such extensions should be granted, and even if granted, the length of such extensionsdevelop. ~~Further, even if our patent is extended, the patent, including the extended portion of the patent, may be held invalid or unenforceable by a court in the United States or a foreign country.~~

Our owned and in-licensed patent estate as of December 31, 2020, on a worldwide basis, includes over 325 granted or pending patent applications world-wide, spread over more than 15 patent families, with 10 granted U.S. patents. The term of individual patents depends upon the laws of the countries in which they are obtained. In the countries in which we currently file, the patent term is 20 years from the earliest date of filing of the first non-provisional patent application in a patent family, which may also serve as a priority application.

In the U.S. by delays encountered during patent prosecution that are caused by the USPTO may also result in lengthened patent term (referred to as Patent Term Adjustment (PTA)). For example, the U.S. Hatch-Waxman Act permits a patent term extension for FDA-approved drugs of up to five years beyond the expiration of the patent. The length of the patent term extension is related to the length of time the drug is under regulatory review and diligence during the review process. Patent term extensions cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval and only one patent covering an approved drug, its method of use or its methods of manufacture may be extended. A similar kind of patent extension, referred to as a Supplementary Protection Certificate, is available in Europe and certain other countries including Japan. Legal frameworks are also available in certain other jurisdictions to extend the term of a patent. The Company applied for PTE for U.S. Patent 8,323,653 upon FDA approval of Uplizna^®. We currently intend to seek patent term extensions on any of our issued patents in any jurisdiction where we have a qualifying patent and the extension is available; however there is no guarantee that the applicable regulatory authorities, including the FDA in the United States, will agree with our assessment of whether such extensions should be granted, and even if granted, the length of such extensions. Further, even if our patent is extended, the patent, including the extended portion of the patent, may be held invalid or unenforceable by a court in the United States or a foreign country.

As with other biotechnology and pharmaceutical companies, our ability to obtain and maintain a proprietary position on our drug candidates and technologies will depend on our success in obtaining effective patent claims on these pending patents and enforcing those claims if granted. However, our pending patent applications, and any patent applications that we may in the future file or license from third parties, may not result in the issuance of patents. We also cannot predict the breadth of claims that may be allowed or enforced in our patents. Furthermore, our competitors may be able to independently develop and commercialize drugs with similar mechanisms of action and duplicate our methods of treatments or strategies without infringing our patents. Because of the extensive time required for clinical development and regulatory review of a drug we may develop, it is possible that, before any of our drugs can be commercialized, any related patent may expire or remain in force for only a short period following commercialization, thereby reducing any advantage of any such patent. Moreover, even our issued patents do not guarantee us the right to practice our technology in relation to the commercialization of our clinical candidates. The area of patent and other intellectual property rights in pharmaceuticals is an evolving one with many risks and uncertainties, and third parties may have blocking patents that could be used to prevent us from commercializing our clinical candidates.

The biotechnology and pharmaceutical industries are characterized by extensive litigation regarding patents and other intellectual property rights. Our ability to obtain and maintain our proprietary position for our product candidates and technology will depend on our success in enforcing the claims that have been granted or may grant. However, any of our patents, including patents that we may rely on to protect our market for approved drugs, may be held invalid or unenforceable by a court. Alternatively, we may decide that it is in our interest to settle a litigation in a manner that affects the term or enforceability of our patent. Changes in either the patent laws or in interpretations of patent laws in the United States and other countries may diminish our ability to protect our inventions and enforce our intellectual property rights. Accordingly, we cannot predict the breadth or enforceability of claims that have been or may be granted in our patents or in third-party patents.

VIB7734 Patent Coverage

VIB7734 is covered by Viela-owned and in-licensed pending and issued patents in multiple jurisdictions. Exclusive of any Patent Term Extension, our current, owned or exclusively licensed, issued patents and pending non-provisional applications covering VIB7734 will expire on dates ranging from 2026 to 2037, where issued, valid and enforceable

We have exclusively licensed from SBI Biotech Co. a patent family comprising issued patents and pending applications in various jurisdictions, including the U.S. The expected year of expiration for this patent family, where issued, valid and enforceable, is 2026, without regard to any extensions or adjustments of term that may be available under national law. This family relates to, for example, monoclonal antibodies, which bind to human ILT7, binds to none of human ILT1, ILT2 and human ILT3, and suppresses interferon-a (IFNa) production from ILT7-expressing cells, or a fragment comprising its antigen binding region.

Trade secrets

In addition to patents, we rely upon unpatented trade secrets and know-how and continuing technological innovation to develop and maintain our competitive position. We seek to protect our proprietary information, in part, using confidentiality agreements with our commercial partners, collaborators, employees, and consultants, and invention assignment agreements with our employees. These agreements are designed to protect our proprietary information and, in the case of the invention assignment agreements, to grant us ownership of technologies that are developed through a relationship with a third party. These agreements may be breached, and we may not have adequate remedies for any breach. In addition, our trade secrets may otherwise become known or be independently discovered by competitors. To the extent that our commercial partners, collaborators, employees, and consultants use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions.

Government Regulation

Government authorities in the United States at the federal, state and local level and in other countries and jurisdictions, including the European Union, extensively regulate, among other things, the research, development, testing, ~~manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution,~~

3435

manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, post-approval monitoring and reporting, marketing and export and import of drug products, including biologic products. Generally, before a new drug can be marketed, considerable data demonstrating its quality, safety and efficacy must be obtained, organized into a format specific for each regulatory authority, submitted for review and approved by the regulatory authority.

U.S. government regulation of biological products

In the United States, the FDA regulates biologics under the Federal Food, Drug, and Cosmetic Act, or FDCA, and the Public Health Service Act, or PHSA, and their implementing regulations. Products are also subject to other federal, state and local statutes and regulations. The process of obtaining regulatory approvals and the subsequent compliance with applicable federal, state, local and foreign statutes and regulations requires the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process or after approval, may subject an applicant to a variety of administrative or judicial sanctions, such as the FDA’s refusal to approve pending biologic license applications, or BLAs, withdrawal of an approval, imposition of a clinical hold, issuance of warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement of profits or civil or criminal penalties.

The process required by the FDA before a biologic may be marketed in the United States generally involves the following:

•

Completion of extensive pre-clinical studies and tests in accordance with applicable regulations, including Good Laboratory Practice, or GLP, regulations and applicable requirements for the humane use of laboratory animals or other applicable regulations;

•

Submission to FDA of an IND which must become effective before human clinical trials may begin;

•

Approval by an independent institutional review board, or IRB, or ethics committee at each clinical trial site before each trial may be initiated;

•

Performance of adequate and well-controlled human clinical trials in accordance with applicable IND regulations, good clinical practices, or GCPs, and other clinical-trial related regulations to evaluate the safety and efficacy of the investigational product for each proposed indication;

•

Submission to FDA of a BLA for marketing approval that includes substantive evidence of safety, purity, and potency from results of pre-clinical testing and clinical trials;

•

A determination by FDA within 60 days of its receipt of a BLA to accept the filing for review;

•

Satisfactory completion of one or more FDA pre-approval inspections of the manufacturing facility or facilities where the biologic will be produced to assess compliance with cGMPs to assure that the facilities, methods and controls used in product manufacture are adequate to preserve the biologic’s identity, strength, quality and purity;

•

Potential FDA audit of the pre-clinical and/or clinical trial sites that generated the data in support of the BLA;

•

Payment of user fees for FDA review of the BLA; and

•

FDA review and approval of the BLA, including satisfactory completion of an FDA advisory committee review, if applicable, prior to any commercial marketing or sale of the product in the United States.

Pre-clinical studies

Before testing any biological product candidate, including our product candidates, in humans, the product candidate must undergo rigorous pre-clinical testing. The pre-clinical developmental stage generally involves laboratory evaluations of drug chemistry, formulation and stability, as well as studies to evaluate toxicity in animals, which support subsequent clinical testing. The sponsor must submit the results of the pre-clinical studies, together with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the IND. An IND is a request for authorization from the FDA to administer an investigational product to humans, and must become effective before human clinical trials may begin.

Pre-clinical studies include laboratory evaluation of product chemistry and formulation, as well as in vitro and animal studies to assess the potential for adverse events and in some cases to establish a rationale for therapeutic use. The conduct of pre-clinical studies is subject to federal regulations and requirements, including GLP regulations for ~~safety/toxicology studies. An IND sponsor must submit the results of the pre-clinical tests, together with manufacturing~~

3536

safety/toxicology studies. An IND sponsor must submit the results of the pre-clinical tests, together with manufacturing information, analytical data, any available clinical data or literature and plans for clinical studies, among other things, to the FDA as part of an IND. Some long-term pre-clinical testing, such as animal tests of reproductive adverse events and carcinogenicity, may continue after the IND is submitted. An IND automatically becomes effective 30 days after receipt by the FDA, unless before that time, the FDA raises concerns or questions related to one or more proposed clinical trials and places the trial on clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. As a result, submission of an IND may not result in the FDA allowing clinical trials to commence.

Clinical trials

The clinical stage of development involves the administration of the investigational product to healthy volunteers or patients under the supervision of qualified investigators, generally physicians not employed by, or under control of, the trial sponsor, in accordance with GCPs, which include the requirement that all research patients provide their informed consent for their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria and the parameters to be used to monitor subject safety and assess efficacy. Each protocol, and any subsequent amendments to the protocol, must be submitted to the FDA as part of the IND. Furthermore, each clinical trial must be reviewed and approved by an IRB for each institution at which the clinical trial will be conducted to ensure that the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the informed consent form that must be provided to each clinical trial subject or his or her legal representative, and must monitor the clinical trial until completed. There also are requirements governing the reporting of ongoing clinical trials and completed clinical trial results to public registries. Information about most clinical trials must be submitted within specific timeframes for publication on the www.clinicaltrials.gov website. Information related to the product, patient population, phase of investigation, study sites and investigators and other aspects of the clinical trial is made public as part of the registration of the clinical trial. Sponsors are also obligated to disclose the results of their clinical trials after completion. Disclosure of the results of these trials can be delayed in some cases for up to two years after the date of completion of the trial. Competitors may use this publicly available information to gain knowledge regarding the progress of development programs.

Human clinical trials are typically conducted in three sequential phases, which may overlap or be combined:

•

Phase 1 clinical trials generally involve a small number of healthy volunteers or disease-affected patients who are initially exposed to a single dose and then multiple doses of the product candidate. The primary purpose of these clinical trials is to assess the metabolism, pharmacologic action, side effect tolerability and safety of the drug.

•

Phase 2 clinical trials involve studies in disease-affected patients to determine the dose required to produce the desired benefits. At the same time, safety and further pharmacokinetic and pharmacodynamic information is collected, possible adverse effects and safety risks are identified and a preliminary evaluation of efficacy is conducted.

•

Phase 3 clinical trials generally involve a larger number of patients at multiple sites and are designed to provide the data necessary to demonstrate the effectiveness of the product for its intended use, its safety in use and to establish the overall benefit/risk relationship of the product and provide an adequate basis for product approval. These trials may include comparisons with placebo and/or other comparator treatments. The duration of treatment is often extended to mimic the actual use of a product during marketing.

Post-approval trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing approval. These trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication, particularly for long-term safety follow up. In certain instances, the FDA may mandate the performance of Phase 4 clinical trials as a condition of approval of a BLA.

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently if serious adverse events occur. The FDA or the sponsor may suspend or terminate a clinical trial at any time or the FDA may impose other sanctions on various grounds, including a finding that the research patients are being exposed to an unacceptable health risk. Similarly, an IRB can refuse, suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the drug has been associated with unexpected serious harm to patients.

Concurrently with clinical trials, companies usually complete additional pre-clinical studies and must also develop additional information about the physical characteristics of the biological product as well as finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. To help reduce the risk of the introduction of adventitious agents with use of biological products, the PHSA emphasizes the importance of manufacturing control for products whose attributes cannot be precisely defined. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the sponsor must develop ~~methods for testing the identity, strength, quality, potency and purity of the final biological product. Additionally,~~

3637

methods for testing the identity, strength, quality, potency and purity of the final biological product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the biological product candidate does not undergo unacceptable deterioration over its shelf life.

BLA review and approval

Assuming successful completion of the required clinical testing, the results of the pre-clinical studies and clinical trials, together with detailed information relating to the product’s chemistry, manufacture, controls and proposed labeling, among other things, are submitted to the FDA as part of a BLA requesting approval to market the product for one or more indications. The BLA must contain proof of safety, purity, potency and efficacy and may include both negative and ambiguous results of pre-clinical studies and clinical trials as well as positive findings. Data may come from company-sponsored clinical trials intended to test the safety and efficacy of a product’s use or from a number of alternative sources, including studies initiated by investigators. To support marketing approval, the data submitted must be sufficient in quality and quantity to establish the safety and efficacy of the investigational product to the satisfaction of the FDA. FDA approval of a BLA must be obtained before a biologic may be marketed in the United States.

In most cases, the submission of a BLA is subject to a substantial application user fee. Under the goals and policies agreed to by the FDA under the Prescription Drug User Fee Act, or PDUFA, for original BLAs, the FDA has ten months from the filing date in which to complete its initial review of a standard application and respond to the applicant, and six months from the filing date for an application with priority review. The FDA does not always meet its PDUFA goal dates, and the review process is often significantly extended by FDA requests for additional information or clarification and a sponsor’s process to respond to such inquiries. This FDA review typically takes twelve months from the date the BLA is submitted to the FDA (for a standard review) and eight months from the date the BLA is submitted (for a priority review) because the FDA has approximately two months after BLA submission to make a “filing” decision.

Before approving a BLA, the FDA will typically conduct a pre-approval inspection of the manufacturing facilities for the new product to determine whether the manufacturing processes and facilities comply with cGMPs. The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. The FDA also may inspect the sponsor and one or more clinical trial sites to assure compliance with GCP requirements and the integrity of the clinical data submitted to the FDA.

Additionally, the FDA may refer applications for novel biologic candidates which present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and under what conditions, if any. The FDA is not bound by recommendations of an advisory committee, but it considers such recommendations when making decisions on approval. The FDA likely will re-analyze the clinical trial data, which could result in extensive discussions between the FDA and the applicant during the review process. The FDA also may require submission of a risk evaluation and mitigation strategy or “REMS” plan if it determines that a REMS is necessary to ensure that the benefits of the drug outweigh its risks and to assure the safe use of the biological product. The REMS plan could include medication guides, physician communication plans, assessment plans and/or elements to assure safe use, such as restricted distribution methods, patient registries or other risk minimization tools. The FDA determines the requirement for a REMS, as well as the specific REMS provisions, on a case-by-case basis. If the FDA concludes a REMS plan is needed, the sponsor of the BLA must submit a proposed REMS. The FDA will not approve a BLA without a REMS, if required.

Under the Pediatric Research Equity Act, or PREA, a BLA or supplement to a BLA must contain data that are adequate to assess the safety and efficacy of the product candidate for the claimed indications in all relevant pediatric populations and to support dosing and administration for each pediatric population for which the product is safe and effective. The FDA may grant deferrals for submission of pediatric data or full or partial waivers. The Food and Drug Administration Safety and Innovation Act, or FDASIA, amended the FDCA to require that a sponsor who is planning to submit a marketing application for a product that includes a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration submit an initial Pediatric Study Plan, or PSP, within sixty days of an end-of-Phase 2 meeting or, if there is no such meeting, as early as practicable before the initiation of the Phase 3 or Phase 2/3 clinical trial. The initial PSP must include an outline of the pediatric study or studies that the sponsor plans to conduct, including trial objectives and design, age groups, relevant endpoints and statistical approach, or a justification for not including such detailed information, and any request for a deferral of pediatric assessments or a full or partial waiver of the requirement to provide data from pediatric studies along with supporting information. The FDA and the sponsor must reach an agreement on the PSP. A sponsor can submit amendments to an agreed upon initial PSP at any time if changes to the pediatric plan need to be considered based on data collected from pre-clinical studies, early phase clinical trials or other clinical development programs.

After the FDA evaluates a BLA, it will issue an approval letter or a Complete Response Letter. An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific indications. A Complete Response Letter indicates that the review cycle of the application is complete and the application will not be approved in ~~its present form. A Complete Response Letter usually describes all of the specific deficiencies in the BLA identified by the~~

3738

its present form. A Complete Response Letter usually describes all of the specific deficiencies in the BLA identified by the FDA. The Complete Response Letter may require additional clinical or other data, additional pivotal Phase 3 clinical trial(s) and/or other significant and time-consuming requirements related to clinical trials, pre-clinical studies or manufacturing. If a Complete Response Letter is issued, the applicant may either resubmit the BLA, addressing all of the deficiencies identified in the letter, or withdraw the application. Even if such data and information are submitted, the FDA may decide that the re-submitted BLA does not satisfy the criteria for approval.

If a product receives regulatory approval, the approval is limited to the conditions of use (e.g., patient population, indication) described in the application. Further, depending on the specific risk(s) to be addressed, the FDA may require that contraindications, warnings or precautions be included in the product labeling, require that post-approval trials, including Phase 4 clinical trials, be conducted to further assess a product’s safety after approval, require testing and surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution and use restrictions or other risk management mechanisms under a REMS, which can materially affect the potential market and profitability of the product. The FDA may prevent or limit further marketing of a product based on the results of post-marketing trials or surveillance programs. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further testing requirements and FDA review and approval.

Orphan drug designation

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic product intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States and for which there is no reasonable expectation that the cost of developing and making the product available in the United States for this type of disease or condition will be recovered from sales of the product in the United States. Orphan drug designation must be requested before submitting a BLA. After the FDA grants orphan drug designation, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process. Orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers. If a product that has orphan designation subsequently receives the first FDA approval for the disease or condition for which it has such designation, the product is entitled to orphan drug exclusivity, which means that the FDA may not approve any other applications to market the same drug for the same indication for seven years from the date of such approval, except in limited circumstances, such as a showing of clinical superiority to the product with orphan exclusivity by means of greater effectiveness, greater safety, by providing a major contribution to patient care or in instances of drug supply issues. Competitors, however, may receive approval of either a different product for the same indication or the same product for a different indication that could be used “off-label” by physicians in the orphan indication, even though the competitor’s product is not approved in the orphan indication. Orphan drug exclusivity also could block the approval of one of our products for seven years if a competitor obtains approval before we do of the same product, as defined by the FDA, for the same indication we are seeking, or if our product candidate is determined to be contained within the scope of the competitor’s product for the same indication or disease. If one of our products designated as an orphan drug receives marketing approval for an indication broader than that which is designated, it may not be entitled to orphan drug exclusivity. Orphan drug status in the European Union has similar, but not identical, requirements and benefits.

Expedited review and approval

The FDA has various programs, including fast track designation, breakthrough therapy designation, accelerated approval and priority review, which are intended to expedite or simplify the process for the development and FDA review of drugs and biologics that are intended for the treatment of serious or life-threatening diseases or conditions and demonstrate the potential to address unmet medical needs. The purpose of these programs is to provide important new drugs and biologics to patients earlier than under standard FDA review procedures.

To be eligible for a fast track designation, the FDA must determine, based on the request of a sponsor, that a product is intended to treat a serious or life-threatening disease or condition and demonstrates the potential to address an unmet medical need by providing a therapy where none exists or a therapy that may be potentially superior to existing therapy based on efficacy or safety factors. Fast track designation provides opportunities for more frequent interactions with the FDA review team to expedite development and review of the product. The FDA may also review sections of the BLA for a fast track product on a rolling basis before the complete application is submitted, if the sponsor and the FDA agree on a schedule for the submission of the application sections, and the sponsor pays any required user fees upon submission of the first section of the BLA.

In addition, under the provisions FDASIA, passed in July 2012, a sponsor can request designation of a product candidate as a “breakthrough therapy.” A breakthrough therapy is defined as a drug or biologic that is intended, alone or in combination with one or more other drugs or biologics, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug or biologic may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. Drugs or biologics designated as breakthrough therapies are also eligible for accelerated approval. The ~~FDA must take certain actions with respect to breakthrough therapies, such as holding timely meetings with and providing~~

3839

FDA must take certain actions with respect to breakthrough therapies, such as holding timely meetings with and providing advice to the product sponsor, intended to expedite the development and review of an application for approval of a breakthrough therapy.

Products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful therapeutic benefit over existing treatments may be eligible for accelerated approval and may be approved on the basis of adequate and well-controlled clinical trials establishing that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than an irreversible effect on morbidity or mortality, or IMM, that is reasonably likely to predict an effect on IMM or other clinical benefit, taking into account the severity, rarity or prevalence of the condition and the availability or lack of alternative treatments. As a condition of approval, the FDA may require a sponsor of a product receiving accelerated approval to perform post-marketing trials to verify and describe the predicted effect on IMM or other clinical endpoint, and the product may be subject to expedited withdrawal procedures.

Once a BLA is submitted for a product intended to treat a serious condition, the FDA may assign a priority review designation if the FDA determines that the product, if approved, would provide a significant improvement in safety or effectiveness. Most products that are eligible for fast track or breakthrough therapy designation may also be considered appropriate to receive a priority review.

Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or decide that the time period for FDA review or approval will not be shortened. Furthermore, fast track designation, breakthrough therapy designation, accelerated approval and priority review do not change the standards for approval and may not ultimately expedite the development or approval process.

Post-approval requirements

Following approval of a new product, the manufacturer and the approved product are subject to pervasive and continuing regulation by the FDA, including, among other things, monitoring and recordkeeping activities, reporting of adverse experiences with the product, product sampling and distribution restrictions, complying with promotion and advertising requirements, which include restrictions on promoting drugs for unapproved uses or patient populations (i.e., “off-label use”) and limitations on industry-sponsored scientific and educational activities. Although physicians may prescribe legally available products for off-label uses, manufacturers may not market or promote such uses. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability. If there are any modifications to the product, including changes in indications, labeling or manufacturing processes or facilities, the applicant may be required to submit and obtain FDA approval of a new BLA or BLA supplement, which may require the applicant to develop additional data or conduct additional pre-clinical studies and clinical trials. The FDA may also place other conditions on approvals including the requirement for a REMS to assure the safe use of the product. A REMS could include medication guides, physician communication plans or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. Any of these limitations on approval or marketing could restrict the commercial promotion, distribution, prescription or dispensing of products. Product approvals may be withdrawn for non-compliance with regulatory standards or if problems occur following initial marketing.

FDA regulations require that products be manufactured in specific approved facilities and in accordance with cGMPs. The cGMP regulations include requirements relating to organization of personnel, buildings and facilities, equipment, control of components and drug product containers and closures, production and process controls, packaging and labeling controls, holding and distribution, laboratory controls, records and reports and returned or salvaged products. The manufacturing facilities for our product candidates must meet cGMP requirements and satisfy the FDA or comparable foreign regulatory authorities’ satisfaction before any product is approved and our commercial products can be manufactured. We rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of our products in accordance with cGMP regulations. These manufacturers must comply with cGMP regulations that require, among other things, quality control and quality assurance, the maintenance of records and documentation and the obligation to investigate and correct any deviations from cGMP. Manufacturers and other entities involved in the manufacture and distribution of approved drugs or biologics are required to register their establishments with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain cGMP compliance. The discovery of conditions that violate these rules, including failure to conform to cGMPs, could result in enforcement actions, and the discovery of problems with a product after approval may result in restrictions on a product, manufacturer or holder of an approved BLA, including voluntary recall and regulatory sanctions as described below.

3940

Once an approval or clearance of a drug is granted, the FDA may withdraw the approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in mandatory revisions to the approved labeling to add new safety information; imposition of post-market or clinical trials to assess new safety risks; or imposition of distribution or other restrictions under a REMS program. Other potential consequences include, among other things:

•

restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;

•

fines, warning letters or other enforcement-related letters or clinical holds on post-approval clinical trials;

•

refusal of the FDA to approve pending BLAs or supplements to approved BLAs, or suspension or revocation of product approvals;

•

product seizure or detention, or refusal to permit the import or export of products;

•

injunctions or the imposition of civil or criminal penalties; and

•

consent decrees, corporate integrity agreements, debarment, or exclusion from federal healthcare programs; or mandated modification of promotional materials and labeling and the issuance of corrective information.

Biosimilars and exclusivity

An abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product was created by the Biologics Price Competition and Innovation Act of 2009, or BPCIA, as part of the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or the Affordable Care Act. This amendment to the PHSA, in part, attempts to minimize duplicative testing. A recent federal district court ruling in Texas struck down the Affordable Care Act in its entirety based on constitutionality. This decision means numerous reforms enacted as part of the Affordable Care Act, but not specifically related to health insurance, such as the BPCIA, would be invalid as well. While the presidential administration and CMS have both stated that the ruling will have no immediate effect, it is unclear how this decision, subsequent appeals, and other efforts to repeal and replace the Affordable Care Act will impact the Affordable Care Act and our business. To date, the FDA has approved a number of biosimilars, and numerous biosimilars have been approved in Europe. The FDA has issued several guidance documents outlining its approach to reviewing and approving biosimilars.

Biosimilarity, which requires that the biological product be highly similar to the reference product notwithstanding minor differences in clinically inactive components and that there be no clinically meaningful differences between the product and the reference product in terms of safety, purity and potency, must be shown through analytical studies, animal studies and a clinical trial or trials. Interchangeability requires that a biological product be biosimilar to the reference product and that the product can be expected to produce the same clinical results as the reference product in any given patient and, for products administered multiple times to an individual, that the product and the reference product may be alternated or switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biological product without such alternation or switch. Complexities associated with the larger, and often more complex, structure of biological products as compared to small molecule drugs, as well as the processes by which such products are manufactured, pose significant hurdles to implementation that are still being worked out by the FDA.

A reference biological product is granted 12 years of data exclusivity from the time of first licensure of the product, and the FDA will not accept an application for a biosimilar or interchangeable product based on the reference biological product until four years after the date of first licensure of the reference product. “First licensure” typically means the initial date the particular product at issue was licensed in the United States. Date of first licensure does not include the date of licensure of (and a new period of exclusivity is not available for) a supplement for the reference product for a subsequent application filed by the same sponsor or manufacturer of the reference product (or licensor, predecessor in interest or other related entity) for a change (not including a modification to the structure of the biological product) that results in a new indication, route of administration, dosing schedule, dosage form, delivery system, delivery device or strength or for a modification to the structure of the biological product that does not result in a change in safety, purity or potency. Therefore, one must determine whether a new product includes a modification to the structure of a previously licensed product that results in a change in safety, purity or potency to assess whether the licensure of the new product is a first licensure that triggers its own period of exclusivity. Whether a subsequent application, if approved, warrants exclusivity as the “first licensure” of a biological product is determined on a case-by-case basis with data submitted by the sponsor.

The BPCIA is complex and only beginning to be interpreted and implemented by the FDA. In addition, recent government proposals have sought to reduce the 12-year reference product exclusivity period. Other aspects of the

4041

BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. As a result, the ultimate impact, implementation and meaning of the BPCIA is subject to significant uncertainty.

U.S. patent term restoration

Depending upon the timing, duration and conditions of FDA marketing approval of our product candidates, one or more of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Amendments, and similar legislation in the European Union. The Hatch-Waxman Amendments permit a patent term extension of up to five years for a patent covering an approved product as compensation for effective patent term lost during product development and the FDA regulatory review process. However, we may not receive an extension if we fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy applicable requirements. Moreover, the length of the extension could be less than we request. Only one patent per approved product can be extended, the extension must be based on the first approval for the product, and the extension cannot extend the total patent term beyond fourteen years from approval. If we are unable to obtain patent term extension or the term of any such extension is less than we request, the period during which we can enforce our patent rights for that product will be shortened and our competitors may obtain approval to market competing products sooner.

European Union drug development, review and approval

In the European Union, our product candidates also may be subject to extensive regulatory requirements. As in the United States, medicinal products can be marketed only if a marketing authorization from the competent regulatory agencies has been obtained.

Similar to the United States, the various phases of pre-clinical and clinical research in the European Union are subject to significant regulatory controls.

The Clinical Trials Directive 2001/20/EC, the Directive 2005/28/EC on GCP, and the related national implementing provisions of the individual EU Member States govern the system for the approval of clinical trials in the European Union. Under this system, an applicant must obtain prior approval from the competent national authority of the EU Member States in which the clinical trial is to be conducted. Furthermore, the applicant may only start a clinical trial at a specific study site after the competent ethics committee has issued a favorable opinion. The clinical trial application must be accompanied by, among other documents, an IMPD (the Common Technical Document) with supporting information prescribed by Directive 2001/20/EC, Directive 2005/28/EC, where relevant the implementing national provisions of the individual EU Member States and further detailed in applicable guidance documents. All suspected unexpected serious adverse reactions to the investigated drug that occur during the clinical trial have to be reported to the competent national authority and the Ethics Committee of the Member State where they occurred.

In April 2014, the new Clinical Trials Regulation, (EU) No 536/2014 (Clinical Trials Regulation) was adopted and it is anticipated to come into application in 2019. The Clinical Trials Regulation will be directly applicable in all the EU Member States, repealing the current Clinical Trials Directive 2001/20/EC. Conduct of all clinical trials performed in the European Union will continue to be bound by currently applicable provisions until the new Clinical Trials Regulation becomes applicable. The extent to which ongoing clinical trials will be governed by the Clinical Trials Regulation will depend on when the Clinical Trials Regulation becomes applicable and on the duration of the individual clinical trial. If a clinical trial continues for more than three years from the day on which the Clinical Trials Regulation becomes applicable the Clinical Trials Regulation will at that time begin to apply to the clinical trial.

The new Clinical Trials Regulation aims to simplify and streamline the approval of clinical trials in the European Union. The main characteristics of the regulation include: a streamlined application procedure via a single entry point, the “EU portal”; a single set of documents to be prepared and submitted for the application as well as simplified reporting procedures for clinical trial sponsors; and a harmonized procedure for the assessment of applications for clinical trials, which is divided in two parts. Part I is assessed by the competent authorities of all EU Member States in which an application for authorization of a clinical trial has been submitted (Member States concerned). Part II is assessed separately by each Member State concerned. Strict deadlines have been established for the assessment of clinical trial applications. The role of the relevant ethics committees in the assessment procedure will continue to be governed by the national law of the concerned EU Member State. However, overall related timelines will be defined by the Clinical Trials Regulation.

To obtain a marketing authorization of a drug in the European Union, we may submit marketing authorization applications, or MAA, either under the so-called centralized or national authorization procedures.

4142

Centralized procedure

The centralized procedure provides for the grant of a single marketing authorization following a favorable opinion by the EMA, that is valid in all EU member states, as well as Iceland, Liechtenstein and Norway. The centralized procedure is compulsory for medicines produced by specified biotechnological processes, products designated as orphan medicinal products, advanced-therapy medicines (such as gene-therapy, somatic cell-therapy or tissue-engineered medicines) and products with a new active substance indicated for the treatment of specified diseases, such as HIV/AIDS, cancer, diabetes, neurodegenerative disorders or autoimmune diseases and other immune dysfunctions and viral diseases. The centralized procedure is optional for products that represent a significant therapeutic, scientific or technical innovation, or whose authorization would be in the interest of public health. Under the centralized procedure the maximum timeframe for the evaluation of an MAA by the EMA is 210 days, excluding clock stops, when additional written or oral information is to be provided by the applicant in response to questions asked by the Committee for Medicinal Products for Human Use, or the CHMP. Accelerated assessment might be granted by the CHMP in exceptional cases, when a medicinal product is expected to be of a major public health interest, particularly from the point of view of therapeutic innovation. The timeframe for the evaluation of an MAA under the accelerated assessment procedure is of 150 days, excluding stop-clocks.

National authorization procedures

There are also two other possible routes to authorize medicinal products in several EU countries, which are available for investigational medicinal products that fall outside the scope of the centralized procedure:

•

Decentralized procedure. Using the decentralized procedure, an applicant may apply for simultaneous authorization in more than one EU country of medicinal products that have not yet been authorized in any EU country and that do not fall within the mandatory scope of the centralized procedure.

•

Mutual recognition procedure. In the mutual recognition procedure, a medicine is first authorized in one EU Member State, in accordance with the national procedures of that country. Following this, further marketing authorizations can be sought from other EU countries in a procedure whereby the countries concerned agree to recognize the validity of the original, national marketing authorization.

Under the above described procedures, before granting the MA, the EMA or the competent authorities of the Member States of the EEA make an assessment of the risk-benefit balance of the product on the basis of scientific criteria concerning its quality, safety and efficacy.

European Union regulatory exclusivity

In the European Union, new products authorized for marketing (i.e., reference products) qualify for eight years of data exclusivity and an additional two years of market exclusivity upon marketing authorization. The data exclusivity period prevents generic applicants from relying on the pre-clinical and clinical trial data contained in the dossier of the reference product when applying for a generic marketing authorization in the European Union during a period of eight years from the date on which the reference product was first authorized in the European Union. The market exclusivity period prevents a successful generic applicant from commercializing its product in the EU until ten years have elapsed from the initial authorization of the reference product in the EU. The ten-year market exclusivity period can be extended to a maximum of eleven years if, during the first eight years of those ten years, the marketing authorization holder obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to their authorization, are held to bring a significant clinical benefit in comparison with existing therapies.

European Union orphan designation and exclusivity

The criteria for designating an orphan medicinal product in the European Union, are similar in principle to those in the United States. Under Article 3 of Regulation (EC) 141/2000, a medicinal product may be designated as orphan if (1) it is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition; (2) either (a) such condition affects no more than five in 10,000 persons in the European Union when the application is made, or (b) the product, without the benefits derived from orphan status, would not generate sufficient return in the European Union to justify investment; and (3) there exists no satisfactory method of diagnosis, prevention or treatment of such condition authorized for marketing in the European Union, or if such a method exists, the product will be of significant benefit to those affected by the condition, as defined in Regulation (EC) 847/2000. Orphan medicinal products are eligible for financial incentives such as reduction of fees or fee waivers and are, upon grant of a marketing authorization, entitled to ten years of market exclusivity for the approved therapeutic indication. The application for orphan designation must be submitted before the application for marketing authorization. The applicant will receive a fee reduction for the marketing authorization application if the orphan designation has been granted, but not if the designation is still pending at the time

4243

the marketing authorization is submitted. Orphan designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

The ten-year market exclusivity in the European Union may be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria for orphan designation, for example, if the product is sufficiently profitable not to justify maintenance of market exclusivity. Additionally, marketing authorization may be granted to a similar product for the same indication at any time if:

•

the second applicant can establish that its product, although similar, is safer, more effective or otherwise clinically superior;

•

the applicant consents to a second orphan medicinal product application; or

•

the applicant cannot supply enough orphan medicinal product.

Rest of the world regulation

For other countries outside of the European Union and the United States, such as countries in Eastern Europe, Latin America or Asia, the requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from jurisdiction to jurisdiction. Additionally, the clinical trials must be conducted in accordance with cGCP requirements and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.

If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Other U.S. healthcare laws

In addition to FDA restrictions on the marketing of pharmaceutical products, other U.S., federal and state healthcare regulatory laws restrict business practices in the pharmaceutical industry. Manufacturing, sales, promotion and other activities following product approval are also subject to regulation by numerous regulatory authorities in the United States in addition to the FDA, including the Centers for Medicare & Medicaid Services, or CMS, other divisions of the Department of Health and Human Services, or HHS, the Department of Justice, the Drug Enforcement Administration, the Consumer Product Safety Commission, the Federal Trade Commission, the Occupational Safety & Health Administration, the Environmental Protection Agency, and state and local governments. For example, in the United States, sales, marketing, scientific and educational activities also must comply with federal and state fraud and abuse laws (including, but not limited to, federal and state anti-kickback and false claims), drug pricing laws, transparency reporting laws, and data privacy laws.

The U.S. federal anti-kickback statute is a key federal fraud and abuse law. The U.S. federal anti-kickback statute prohibits, among other things, any person or entity from knowingly and willfully offering, paying, soliciting, receiving or providing any remuneration, directly or indirectly, overtly or covertly, to induce or in return for purchasing, leasing, ordering or arranging for or recommending the purchase, lease or order of any good, facility, item or service reimbursable, in whole or in part, under Medicare, Medicaid or other federal healthcare programs. The term “remuneration” has been broadly interpreted to include anything of value. The anti-kickback statute has been interpreted to apply to arrangements between pharmaceutical and medical device manufacturers on the one hand and prescribers, purchasers, formulary managers and beneficiaries on the other hand. Recently, pharmaceutical manufacturers’ patient support activities have been increasingly scrutinized as potentially providing prohibited remuneration to patients (and where such services ease providers’ administrative burdens, to providers as well) where such activities are not appropriately structured to comply with the U.S. federal anti-kickback statute (and other applicable healthcare fraud and abuse laws and government guidance). Although there are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution, the exceptions and safe harbors are drawn narrowly. Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not meet the requirements of a statutory or regulatory exception or safe harbor. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor does not make the conduct per se illegal under the U.S. federal anti-kickback statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all its facts and circumstances. Several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the statute has been violated. In addition, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. Moreover, a claim including items or services resulting from a violation of the U.S. federal anti-kickback statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act. The majority of states also have anti-kickback laws, which establish similar

4344

prohibitions and, in some cases, may apply to items or services reimbursed by any third-party payor, including commercial insurers, or to self-pay patients.

The federal false claims and civil monetary penalties laws, including the civil False Claims Act, prohibit, among other things, any person or entity from knowingly presenting, or causing to be presented, a false, fictitious or fraudulent claim for payment to, or approval by, the federal government, knowingly making, using or causing to be made or used a false record or statement material to a false or fraudulent claim to the federal government, or knowingly making a false statement to avoid, decrease or conceal an obligation to pay money to the U.S. federal government. A claim includes “any request or demand” for money or property presented to the U.S. government. Actions under the civil False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of the government. Violations of the civil False Claims Act can result in very significant monetary penalties and treble damages. As noted above, violations of the U.S. federal anti-kickback statute can give rise to False Claims Act violations. In addition, companies have been prosecuted for causing false claims to be submitted because of the companies’ marketing of products for unapproved (e.g., off-label), and thus non-covered, uses. In addition, the civil monetary penalties statute imposes penalties against any person who is determined to have presented or caused to be presented a claim to a federal health program that the person knows or should know is for an item or service that was not provided as claimed or is false or fraudulent. Many states also have similar fraud and abuse statutes or regulations that apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor.

Other U.S. healthcare laws and regulations may affect our current or future ability to operate. Federal laws require pharmaceutical manufacturers to report certain calculated product prices to the government or provide certain discounts or rebates to government authorities or private entities, often as a condition of reimbursement under federal healthcare programs. Some states also require reporting of certain drug prices or explanations for price increases.

The federal transparency requirements under the so-called federal “sunshine act” or Open Payments Act require certain manufacturers of drugs, devices, biologics and medical supplies reimbursed under Medicare, Medicaid, or the State Children’s Health Insurance Program to report to HHS information related to payments and other transfers of value provided to physicians and teaching hospitals and, beginning with transfers of value occurring in 2021, other healthcare practitioners, as well as ownership and investment interests held by physicians and their immediate family members. Analogous state laws and regulations require pharmaceutical companies to implement compliance programs including certain standards, to limit financial interactions with healthcare providers, or to track and report gifts, compensation and other remuneration provided to physicians and other health care providers.

In addition, products must meet applicable child-resistant packaging requirements under the U.S. Poison Prevention Packaging Act. Manufacturing, sales, promotion and other activities also are potentially subject to federal and state consumer protection and unfair competition laws. The distribution of biologic and pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage and security requirements intended to prevent the unauthorized sale of pharmaceutical products.

HIPAA and subsequent amendments establish certain requirements related to the privacy, security, and transmission of individually identifiable health information apply to many healthcare providers, physicians and third-party payors with whom we interact, as do state health information privacy and data breach notification laws, which govern the collection, use, disclosure, and protection of health-related and other personal information, many of which differ from each other in significant ways and often are not pre-empted by HIPAA, thus complicating compliance efforts.

Because of the breadth of these laws and the narrowness of available exceptions and safe harbors, our business activities could potentially be subject to challenge under one or more of such laws. The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulations. Federal and state enforcement bodies have recently increased their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Given the significant size of actual and potential settlements, we expect that the government authorities will continue to devote substantial resources to investigating healthcare providers’ and manufacturers’ compliance with applicable fraud and abuse laws.

Ensuring that business arrangements with third parties comply with applicable healthcare laws and regulations is costly and time consuming. If business operations are found to be in violation of any of the laws described above or any other applicable governmental regulations a pharmaceutical manufacturer may be subject to penalties, including civil, criminal and administrative penalties, damages, fines, disgorgement of profits, individual imprisonment, exclusion from governmental funded healthcare programs, such as Medicare and Medicaid, contractual damages, reputational harm, diminished profits and future earnings, additional reporting obligations and oversight if subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, and curtailment or restructuring of operations, any of which could adversely affect a pharmaceutical manufacturer’s ability to operate its business and the results of its operations.

Similar foreign laws and regulations, which may include, for instance, applicable post-marketing requirements, anti-fraud and abuse laws and implementation of corporate compliance programs and reporting of payments or other transfers

4445

of value to healthcare professionals, may apply to us to the extent that any of our product candidates, once approved, are sold in a country other than the United States.

Coverage, pricing and reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any biological products for which we obtain regulatory approval. The United States government, state legislatures and foreign governments have shown significant interest in implementing cost containment programs to limit the growth of government-paid healthcare costs, including price-controls, restrictions on reimbursement and requirements for substitution of generic products for branded drug and biologic products. In the United States and markets in other countries, patients who are prescribed products generally rely on third-party payors to reimburse all or part of the associated healthcare costs. Providers and patients are unlikely to use our products unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our products. As a result, if approved, sales of our product candidates will depend, in part, on the availability of coverage and adequate reimbursement from third-party payors. Third-party payors include government authorities, managed care plans, private health insurers and other organizations.

In the United States, the process for determining whether a third-party payor will provide coverage for a biological product typically is separate from the process for setting the price of such product or for establishing the reimbursement rate that the payor will pay for the product once coverage is approved. With respect to biologics, third-party payors may limit coverage to specific products on an approved list, also known as a formulary, which might not include all of the FDA-approved products for a particular indication, or place products at certain formulary levels that result in lower reimbursement levels and higher cost-sharing obligations imposed on patients. A decision by a third-party payor not to cover our product candidates could reduce physician utilization of a product. Moreover, a third-party payor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate will be approved. Adequate third-party reimbursement may not be available to enable a manufacturer to maintain price levels sufficient to realize an appropriate return on its investment in product development. Additionally, coverage and reimbursement for products can differ significantly from payor to payor. One third-party payor’s decision to cover a particular medical product does not ensure that other payors will also provide coverage for the medical product, or will provide coverage at an adequate reimbursement rate. As a result, the coverage determination process usually requires manufacturers to provide scientific and clinical support for the use of their products to each payor separately and is a time-consuming process.

As noted above, the marketability of any products for which we receive regulatory approval for commercial sale may suffer if the government and third-party payors fail to provide coverage and adequate reimbursement. There is an emphasis on cost containment measures in the United States and we expect will continue to increase the pressure on pharmaceutical pricing. Coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future. Third-party payors are increasingly challenging the prices charged for medical products and services, examining the medical necessity and reviewing the cost-effectiveness of pharmaceutical products, in addition to questioning safety and efficacy. If third-party payors do not consider a product to be cost-effective compared to other available therapies, they may not cover that product after FDA approval or, if they do, the level of payment may not be sufficient to allow a manufacturer to sell its product at a profit.

Within the United States, if we obtain appropriate approval in the future to market any of our oral drug product candidates, those products could potentially be covered by various federal healthcare programs as well as purchased by government agencies. The participation in such programs or the sale of products to such agencies is subject to regulation. The marketability of any products for which we receive regulatory approval for commercial sale may suffer if such payors fail to provide adequate coverage and reimbursement.

Medicaid is a joint federal and state program that is administered by the states for low income and disabled beneficiaries. Under the Medicaid Drug Rebate Program, participating manufacturers are required to pay a rebate for each unit of product reimbursed by the state Medicaid programs. The amount of the rebate for each product is set by law and may be subject to an additional discount if certain pricing increases more than inflation.

Medicare is a federal program that is administered by the federal government that covers individuals age 65 and over as well as those with certain disabilities. Drugs that are not usually self-administered, such as infusion drugs, may be covered under Medicare Part B. Medicare Part B drugs are generally reimbursed at the “average sales price” of the drug plus 6%. Oral or other self-administered drugs may be covered under Medicare Part D. Medicare Part D provides coverage to enrolled Medicare patients for self-administered drugs (i.e., drugs that do not need to be injected or otherwise administered by a physician). Medicare Part D is administered by private prescription drug plans approved by the U.S. government and each drug plan establishes its own Medicare Part D formulary for prescription drug coverage and pricing, which the drug plan may modify from time-to-time. The prescription drug plans negotiate pricing with manufacturers and may condition formulary placement on the availability of manufacturer discounts. Since 2011, manufacturers with marketed brand name drugs have been required to provide a discount on brand name prescription drugs utilized by

4546

Medicare Part D beneficiaries when those beneficiaries reach the coverage gap in their drug benefits (initially 50% but increased to 70% in 2019).

Drug products are subject to discounted pricing when purchased by federal agencies via the Federal Supply Schedule, or FSS. FSS participation is required for a drug product to be covered and reimbursed by certain federal agencies and for coverage under Medicaid, Medicare Part B and the Public Health Service, or PHS pharmaceutical pricing program. FSS pricing is negotiated periodically with the Department of Veterans Affairs. FSS pricing is intended not to exceed the price that a manufacturer charges its most-favored non-federal customer for its product. In addition, prices for drugs purchased by the Veterans Administration, Department of Defense (including drugs purchased by military personnel and dependents through the TRICARE retail pharmacy program), Coast Guard, and PHS are subject to a cap on pricing (known as the “federal ceiling price”) and may be subject to an additional discount if pricing increases more than the rate of inflation.

To maintain coverage of drugs under the Medicaid Drug Rebate Program, manufacturers are required to extend discounts to certain purchasers under the PHS pharmaceutical pricing program. Purchasers eligible for discounts include hospitals that serve a disproportionate share of financially needy patients, community health clinics and other entities that receive health services grants from the PHS.

In addition, in many foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing and reimbursement vary widely from country to country. In the European Union, governments influence the price of products through their pricing and reimbursement rules and control of national healthcare systems that fund a large part of the cost of those products to consumers. Some jurisdictions operate positive and negative list systems under which products may only be marketed once a reimbursement price has been agreed to by the government. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost effectiveness of a particular product to currently available therapies. Other member states allow companies to fix their own prices for medicines, but monitor and control company profits. There can be no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any of our products. The downward pressure on healthcare costs in general, particularly prescription products, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, in some countries, cross border imports from low-priced markets exert a commercial pressure on pricing within a country.

Healthcare reform and potential changes to healthcare laws

The FDA’s and other regulatory authorities’ policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. For example, in December 2016, the 21st Century Cures Act, or Cures Act, was signed into law. The Cures Act, among other things, is intended to modernize the regulation of drugs and devices and to spur innovation, but its ultimate implementation is uncertain. In addition, in August 2017, the FDA Reauthorization Act was signed into law, which reauthorized the FDAs user fee programs and included additional drug and device provisions that build on the Cures Act. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we otherwise may have obtained and we may not achieve or sustain profitability, which would adversely affect our business, prospects, financial condition and results of operations.

A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and other third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medical products and services, implementing reductions in Medicare and other healthcare funding and applying new payment methodologies. For example, in March 2010, the Affordable Care Act was enacted, which, among other things, increased the minimum Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate Program; introduced a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected; extended the Medicaid Drug Rebate Program to utilization of prescriptions of individuals enrolled in Medicaid managed care plans; imposed mandatory discounts for certain Medicare Part D beneficiaries as a condition for manufacturers’ outpatient drugs coverage under Medicare Part D; subjected drug manufacturers to new annual fees based on pharmaceutical companies’ share of sales to federal healthcare programs; imposed a new federal excise tax on the sale of certain medical devices; and established a Center for Medicare Innovation at the CMS to test innovative payment and service delivery models to lower Medicare and Medicaid spending.

4647

Since its enactment, there have been judicial and Congressional challenges to certain aspects of the Affordable Care Act, and we expect there will be additional challenges and amendments to the Affordable Care Act in the future. The current Presidential administration and members of the U.S. Congress have indicated that they may continue to seek to modify, repeal or otherwise invalidate all, or certain provisions of, the Affordable Care Act. Most recently, the Tax Cuts and Jobs Acts was enacted, which, among other things, removes penalties for not complying with the individual mandate to carry health insurance. A recent federal district court ruling struck down the Affordable Care Act in its entirety. While the presidential administration and CMS have both stated that the ruling will have no immediate effect, it is unclear how this decision, subsequent appeals, if any, and other efforts to repeal and replace the Affordable Care Act will impact the Affordable Care Act and our business.

In addition, other legislative changes have been proposed and adopted in the United States since the Affordable Care Act that affect healthcare expenditures. Recently, there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs and reform government program reimbursement methodologies for pharmaceutical and biologic products.

Other changes include the Budget Control Act of 2011, which, among other things, included aggregate reductions of Medicare payments to providers of 2% per fiscal year and that will remain in effect through 2027 unless additional action is taken by Congress. Individual states in the United States have become increasingly active in passing legislation and implementing regulations designed to control biotechnology and pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action, either in the United States or abroad. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services.

~~Employees~~Human Capital

As of December 31, ~~2019~~2020, we had ~~139~~170 full-time employees, including 5370 in research and development, 1523 in manufacturing, operations, and quality assurance, 4243 in commercialization and 2934 in general and administrative functions. We have no collective bargaining agreements with our employees, and we have not experienced any work stoppages. We consider our relations with our employees to be good.

We hire and maintain an experienced, committed, diverse, inclusive and highly motivated workforce. Effective attraction, development, and retention of human resource talent, or human capital, is vital to the success of our mission-driven growth strategy. We face intense competition for qualified individuals from numerous pharmaceutical and biotechnology companies, universities, governmental entities and other research institutions, and we believe that our future success will depend in large part on our continued ability to attract and retain highly skilled employees. To attract qualified applicants to our company and retain our employees, we offer a competitive rewards package consisting of base salary and cash target bonus, a comprehensive benefit package and equity compensation.

We want our employees to learn, grow and look for ways to help develop skills through industry, company and functional training, as well as mentoring opportunities. We offer a robust set of career-enhancing learning experiences and initiatives to all employees, aligned with our mission, vision, and values.

Item 1A. Risk Factors.

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, the section of this Annual Report on Form 10-K entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operation” and our consolidated financial statements and related notes, before investing in our common stock. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that affect us. If any of the following risks occur, our business, operating results and prospects could be materially harmed. In that event, the price of our common stock could decline, and you could lose part or all of your investment. We have marked with an asterisk (*) those risk factors that reflect changes from the similarly titled risk factors included in the Prospectus for our IPO filed pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended, or the Securities Act, on October 4, 2019 (the “Prospectus”).

Summary of Risk Factors

Our business is subject to numerous risks and uncertainties, including those highlighted in this section below, that represent challenges that we face in connection with the successful implementation of our strategy. The occurrence of one or more of the events or circumstances described in more detail in the risk factors below, alone or in combination with other events or circumstances, may have an adverse effect on our business, cash flows, financial condition and results of operations. Such risks include, but are not limited to:

•

The conditions under the Merger Agreement to Parent’s consummation of the Offer and our subsequent Merger with Purchaser may not be satisfied at all or in the anticipated timeframe.

•

While Parent’s Offer and the proposed Merger are pending, we are subject to business uncertainties and contractual restrictions that could disrupt our business.

•

Our executive officers and directors may have interests that are different from, or in addition to, those of our stockholders generally.

•

Litigation filed or that may be filed against us and/or the members of our board of directors could prevent or delay the consummation of the Merger.

•

In the event that the Merger is not consummated, the trading price of our common stock and our future business and results of operations may be negatively affected.

•

If the Merger Agreement is terminated, we may, under certain circumstances, be obligated to pay a termination fee to Parent. These costs could require us to use available cash that would have otherwise been available for other uses.

•

We have incurred significant operating losses since our inception. We expect to incur losses for the foreseeable future and may never achieve or maintain profitability.

•

Our limited operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability.

•

We will need substantial additional funding. If we are unable to raise capital when needed, we would be compelled to delay, reduce or eliminate our product development programs or commercialization efforts.

•

We depend heavily on the success of inebilizumab, VIB4920 and VIB7734, which are in various stages of clinical development and commercialization. If we are unable to advance our product candidates in clinical development, obtain regulatory approval and ultimately commercialize our product candidates, or experience significant delays in doing so, our business will be materially harmed.

•

Clinical drug development involves a lengthy and expensive process, with an uncertain outcome. We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our product candidates.

•

If we experience delays or difficulties in the enrollment of patients in clinical trials, development of our product candidates may be delayed or prevented, which would have a material adverse effect on our business.

•

The outcome of pre-clinical testing and early clinical trials may not be predictive of the success of later clinical trials, and the results of our clinical trials may not satisfy the requirements of the FDA or comparable foreign regulatory authorities.

•

If we do not achieve our projected development and commercialization goals in the timeframes we announce and expect, the commercialization of Uplizna^® or any additional product candidates, if approved, may be delayed, and our business will be harmed.

•

If we are not able to obtain, or if there are delays in obtaining, required marketing approvals, we will not be able to commercialize our product candidates, and our ability to generate revenue will be materially impaired.

•

Our product candidates may cause undesirable side effects that could delay or prevent their marketing approval, limit their commercial potential, or result in significant negative consequences following marketing approval, if any.

•

Our future growth may depend, in part, on our ability to penetrate foreign markets, where we would be subject to additional regulatory burdens and other risks and uncertainties.

•

We may be subject to, or may in the future become subject to, U.S. federal and state, and foreign laws and regulations imposing obligations on how we collect, use, disclose, store and process personal information. Our actual or perceived failure to comply with such obligations could result in liability or reputational harm and could harm our business. Ensuring compliance with such laws could also impair our efforts to maintain and expand our customer base, and thereby decrease our revenue.

•

Biologics carry unique risks and uncertainties, which could have a negative impact on future results of operations.

•

We are reliant on AstraZeneca for a period of time for certain services and for the clinical supplies of our product candidates and the commercial supplies of Uplizna^®.

•

We rely on, and expect to continue to rely on, third parties to conduct our clinical trials for our product candidates. If these third parties do not successfully carry out their contractual duties, comply with regulatory requirements or meet expected deadlines, we may not be able to obtain marketing approval for or commercialize our product candidates, and our business could be substantially harmed.

•

We contract with third parties for the manufacture of our product candidates for nonclinical studies and clinical trials and expect to continue to do so for commercialization. This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or products or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization efforts.

•

We, or our third-party manufacturers, may be unable to successfully scale-up manufacturing of our product candidates in sufficient quality and quantity, which would delay or prevent us from developing our product candidates and commercializing approved products, if any

•

The third parties upon which we rely for the supply of source materials, cell cultures and biological products are our sole sources of supply and have limited capacity, and the loss of any of these suppliers could harm our business.

•

Uplizna^®, which received FDA approval in June 2020, or any of our product candidates that receive marketing approval, if any, may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success.

•

We face substantial competition, which may result in others discovering, developing or commercializing competing products before or more successfully than we do.

•

Uplizna^®, as well as any product candidates that we are able to commercialize, if any, may become subject to unfavorable pricing regulations or third-party coverage and reimbursement policies, which would harm our business.

•

We currently have a focused marketing and sales force. If we are unable to establish effective sales or marketing capabilities or enter into agreements with third parties to sell or market our product candidates, we may not be able to effectively sell or market our product candidates, if approved, or generate product revenues

•

The sizes of the patient populations suffering from some of the diseases we are targeting are small and based on estimates that may not be accurate.

•

If we are unable to obtain and maintain intellectual property protection for our technology and products, or if the scope of the intellectual property protection obtained is not sufficiently broad, our competitors could commercialize technology and products similar or identical to ours, and our ability to successfully commercialize our technology and products may be impaired.

•

Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain and could have a material adverse effect on the success of our business.

•

If we fail to comply with our obligations in the agreements under which we license intellectual property and other rights from third parties or otherwise experience disruptions to our business relationships with our licensors, we could lose license rights that are important to our business.

•

Our intellectual property in-licenses with third parties may be subject to disagreements over contract interpretations, which could narrow the scope of our rights to the relevant intellectual property or technology or increase our financial or other obligations to our licensors.

•

We may not be able to effectively enforce our intellectual property rights throughout the world.

•

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

•

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

•

We expect to expand our development and regulatory capabilities and potentially implement sales, marketing and distribution capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.

•

Unfavorable global economic conditions could adversely affect our business, financial condition or results of operations.

•

A pandemic, epidemic, or outbreak of an infectious disease, such as COVID-19 may materially and adversely affect our business and our financial results.

•

Our executive officers, directors and principal stockholders and their affiliates, if they choose to act together, will continue to have the ability to exercise significant influence over all matters submitted to stockholders for approval.

•

Our ability to use our net operating loss carryforwards and certain other tax attributes to offset future taxable income may be limited.

•

Our third amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Risks Related to the Merger Agreement

The conditions under the Merger Agreement to Parent’s consummation of the Offer and our subsequent Merger with Purchaser may not be satisfied at all or in the anticipated timeframe.

Under the terms of the Merger Agreement, the consummation of Parent’s pending Offer and subsequent Merger is subject to customary conditions. Satisfaction of certain of the conditions is not within our control, and difficulties in otherwise satisfying the conditions may prevent, delay, or otherwise materially adversely affect the consummation of the pending Offer and subsequent Merger. These conditions include, among other things, there being validly tendered (and not validly withdrawn), a number of shares of our common stock that, considered together with all other shares of our common stock beneficially owned by Parent or any of its wholly owned subsidiaries (including Purchaser), subject to certain conditions, represent one more than 50% of the sum of (i) the total number of outstanding shares of our common stock at the expiration of the Offer, and (ii) the aggregate number of shares of our common stock issuable to holders of options (“Company Options”) to purchase shares of our common stock from whom we have received notices of exercise prior to the expiration of the Offer (and as to which shares of our common stock have not yet been issued to such exercising holders of Company Options). We cannot predict with certainty whether and when any of the required conditions will be satisfied. If the Merger does not receive, or timely receive, the required regulatory approvals and clearances, or if another event occurs delaying or preventing the Merger, such delay or failure to complete the Merger may create uncertainty or otherwise have negative consequences that may materially and adversely affect our financial condition and results of operations, as well as the price per share for our common stock.

While Parent’s Offer and the proposed Merger are pending, we are subject to business uncertainties and contractual restrictions that could disrupt our business.

Whether or not the pending Offer and subsequent Merger is consummated, the Merger may disrupt our current plans and operations, which could have an adverse effect on our business and financial results. The pendency of the pending Offer and subsequent Merger may also divert management’s attention and our resources from ongoing business and operations, and our employees and other key personnel may have uncertainties about the effect of the pending Offer and

subsequent Merger, and the uncertainties may impact our ability to retain, recruit, and hire key personnel while the Merger is pending or if it fails to close.

The preparations for the consummation of the Merger have placed and we expect will continue to place a significant burden on many of our management, employees and on our internal resources. The diversion of management’s attention away from operating our business in the ordinary course could adversely affect our financial results. Also, if, despite our efforts, key personnel depart because of these uncertainties and burdens, or because they do not wish to remain with the combined company, our business and results of operations may be adversely affected. We have incurred and will continue to incur significant expenses due to legal, advisory, printing and financial services fees related to the Merger. These expenses must be paid regardless of whether the Merger is consummated, which may materially and adversely affect our financial condition and results of operations.

Furthermore, we cannot predict how our business partners will view or react to the pending Offer and subsequent Merger upon consummation. If we are unable to reassure our business partners to continue transacting business with us, our financial condition and results of operations may be adversely affected.

In addition, the Merger Agreement generally requires us to operate our business and operations in the ordinary course pending consummation of the Merger and also restricts us from taking certain actions without Parent’s prior written consent during the interim period between the execution of the Merger Agreement and the effective time of the Merger (or the date on which the Merger Agreement is earlier terminated). For these and other reasons, the pendency of the proposed Merger could adversely affect our business and results of operations.

Our executive officers and directors may have interests that are different from, or in addition to, those of our stockholders generally.

Our executive officers and directors may have interests in the Merger that are different from, or are in addition to, those of our stockholders generally. These interests include direct or indirect ownership of our common stock and stock options, and for executive officers, employment agreements, retention bonuses and employee benefits following the completion of the pending Offer and subsequent Merger.

Litigation filed or that may be filed against us and/or the members of our board of directors could prevent or delay the consummation of the Merger.

Lawsuits filed, or that may be filed, could delay or prevent our acquisition by Parent, divert the attention of our management and employees from our day-to-day business and otherwise adversely affect us financially. The outcome of any lawsuit filed or that may be filed challenging the Merger is uncertain. One of the conditions to the closing of the Merger is that there has not been issued by any court of competent jurisdiction and remains in effect any judgment, temporary restraining order, preliminary or permanent injunction or other order preventing the consummation of the Merger. Accordingly, if any lawsuit (including but not limited to the legal proceedings discussed in this report in Part I, Item 3 — “Legal Proceedings”) is successful in obtaining an order enjoining the Merger, then the Merger may not be consummated within the expected time frame, or at all, and could result in substantial costs, including but not limited to, costs associated with the indemnification of our directors and officers.

In the event that the Merger is not consummated, the trading price of our common stock and our future business and results of operations may be negatively affected.

The conditions to the consummation of the pending Offer and subsequent Merger may not be satisfied, as noted above. If the Merger is not consummated, we would remain liable for significant transaction costs, and the focus of our management would have been diverted from seeking other potential strategic opportunities, in each case without realizing any benefits of the Merger. For these and other reasons, not consummating the Merger could adversely affect our business and results of operations.

Furthermore, if the pending Offer and subsequent Merger are not consummated, the price of our common stock may decline significantly from the current market price, which we believe reflects a market assumption that the Merger will be consummated. Further, a failure of the Merger may result in negative publicity and a negative impression of us in the investment community, and have a negative impact on our ability to raise additional financing in the future. Finally, any disruptions to our business resulting from the announcement and pendency of the Merger, including any adverse changes in our relationships with our business partners and employees or recruiting and retention efforts, could continue or accelerate in the event of a failed transaction.

If the Merger is not completed, in certain circumstances, we could be required to pay a termination fee of $107.0 million to Parent. If the Merger Agreement is terminated, the termination fee we may be required to pay, if any, under the Merger Agreement may require us to use available cash that would have otherwise been available for general corporate purposes or other uses. For these and other reasons, termination of the Merger Agreement could materially and adversely affect our business, results of operations or financial condition, which in turn would materially and adversely affect the price per share of our common stock.

The following risk factors assume that we remain a stand-alone company except as otherwise noted

Risks Related to Our Financial Position and Need For Additional Capital

We have incurred significant operating losses since our inception. We expect to incur losses for the foreseeable future and may never achieve or maintain profitability.*

We have incurred significant operating losses since our inception, including an operating loss of $86153.49 million, $89.7 million, and $~~190~~192.3 million for the years ended December 31 2020, 2019, and 2018, respectively. To date, we have financed our operations through private placements of our preferred stock and ~~the~~public ~~IPO.~~offering Weof ~~have~~our ~~not~~common ~~commercialized any products and have never generated any revenue from product sales~~stock. We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future. The operating losses we incur may fluctuate significantly from quarter-to-quarter and year-to-year. We anticipate that our expenses will increase substantially if and as we:

• ~~seek approval and~~ pursue commercial activities and manufacturing for ~~inebilizumab~~Uplizna® for treatment in patients with NMOSD;

•

continue development of our product candidates, including initiating additional clinical trials of inebilizumab, VIB4920 and VIB7734;

•

identify, acquire and develop new product candidates;

•

initiate nonclinical studies and clinical trials for any additional product candidates that we may pursue in the future;

•

seek marketing approvals for our product candidates that successfully complete clinical trials;

•

continue to establish a sales, marketing and distribution infrastructure to commercialize any products for which we may obtain marketing approval;

•

achieve market acceptance of our product candidates in the medical community and with third-party payors;

•

maintain, expand and protect our intellectual property portfolio;

•

attract, hire and retain additional personnel;

•

enter into additional collaboration arrangements, if any, for the development of our product candidates or in-license other products and technologies;

•

make royalty, milestone or other payments under current and any future in-license or collaboration agreements;

• add operational, financial and management information systems and personnel, including personnel to support our product development and planned future commercialization efforts; ~~and~~

•

encounter developments related to the coronavirus pandemic and impact of it and COVID-19 on the costs and timing associated with the conduct of our clinical trials and other related activities; and

•

incur increased costs as a result of operating as a public company.

Because of the numerous risks and uncertainties associated with developing pharmaceutical drugs, we are unable to predict the extent of any future losses or when we will become profitable, if at all. In addition, our expenses could increase beyond expectations if we are required by the FDA or foreign regulatory agencies, to perform nonclinical studies and clinical trials in addition to those that we currently anticipate, or if there are any delays in our or our partners completing clinical trials or the development of any of our product candidates.

To become and remain profitable, we must develop and eventually commercialize a product or products with significant product revenue. This will require us to be successful in a range of challenging activities, including the following:

•

completing clinical trials of our product candidates that meet their clinical endpoints;

•

submitting applications for and obtaining marketing approval for our product candidates;

•

establishing a new sales and marketing presence for, or entering into a collaboration with respect to the sales and marketing of, our product candidates;

•

manufacturing, marketing and selling those products for which we may obtain marketing approval and satisfying any post-marketing regulatory requirements;

•

achieving market acceptance of our product candidates in the medical community and with third-party payors;

•

maintaining, protecting and expanding our portfolio of intellectual property rights, including patents, trade secrets and know-how; and

•

attracting, hiring and retaining additional personnel.

In cases where we are successful in obtaining marketing approval for one or more of our product candidates, our revenue will be dependent, in part, upon the size of the markets in the territories for which we gain marketing approval, the accepted price for the product, the ability to obtain coverage and adequate reimbursement, and ownership of commercial rights for that territory. If the number of our addressable patients is not as significant as we estimate, the indication approved by regulatory authorities is narrower than we expect or the treatment population is narrowed by competition, physician choice or treatment guidelines, we may not generate significant revenue of such products, even if approved.

~~Even~~The ifrevenue we do generate ~~revenues, they~~ may not be significant or large enough to achieve profitability. If we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis and we will continue to incur substantial research and development and other expenditures to develop and market additional product candidates. Our failure to become and remain profitable would decrease our value and could impair our ability to raise capital, maintain our discovery and nonclinical development efforts, expand our business or continue our operations and may require us to raise additional capital that may dilute your ownership interest. A decline in our value could also cause you to lose all or part of your investment.

Our limited operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability.

We are a ~~clinical-stage~~ biopharmaceutical company. Biopharmaceutical drug development is a highly speculative undertaking and involves a substantial degree of risk. We were incorporated in December 2017, and our operations to date have been limited to organizing and staffing our company, business planning, raising capital, developing our technology, identifying potential product candidates, undertaking nonclinical studies and conducting clinical trials. ~~Each~~Our commercial product and each of our ~~five~~ current product candidates was acquired from MedImmune in February 2018. Accordingly, prior to the February 2018 asset purchase, all nonclinical studies and clinical trials related to our current product candidates were conducted by MedImmune. We have not yet demonstrated our ability to successfully obtain marketing approvals, manufacture a commercial scale product or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization. Typically, it takes several years to develop one new drug from the time it is discovered to when it is available for treating patients. In addition, as a new business, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors. We will need to ~~transition~~continue transitioning from a company with a research focus to a company capable of supporting commercial activities while maintaining a research focus. We may not be successful in such a transition.

the scope, progress, results and costs of nonclinical development, laboratory testing and clinical trials for our product candidates;

•

the scope, prioritization and number of our research and development programs;

•

the costs, timing and outcome of regulatory review of our product candidates;

•

the extent to which we enter into non-exclusive, jointly funded clinical research collaboration arrangements, if any, for the development of our product candidates in combination with other companies’ products;

•

our ability to establish collaboration arrangements for the development of our product candidates on favorable terms, if at all;

•

the achievement of milestones or occurrence of other developments that trigger payments under any collaboration agreements into which we enter, if any;

•

the extent to which we are obligated to reimburse, or entitled to reimbursement of, clinical trial costs under future collaboration agreements, if any;

•

the extent to which we acquire or in-license other product candidates and technologies;

•

revenue, if any, received from commercial sales of our product candidates, should any of our product candidates receive marketing approval;

•

the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;

•

our efforts to enhance operational systems and our ability to attract, hire and retain qualified personnel; and

•

the costs associated with being a public company.

Conducting nonclinical studies and clinical trials is a time-consuming, expensive and uncertain process that can take years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve significant product sales. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, may be derived from sales of products that may not be commercially available for several years, if ever. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives.

Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our product candidates. Volatility in the financial markets have generally made equity and debt financing more difficult to obtain and may have a material adverse effect on our ability to meet our fundraising needs. We cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to us, if at all. Moreover, the terms of any financing may adversely affect the holdings or the rights of our stockholders and the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of our shares to decline.

If we are unable to obtain funding on a timely basis, we may be required to significantly curtail, delay or discontinue one or more of our research or development programs or the commercialization of any product candidate or be unable to expand our operations or otherwise capitalize on our business opportunities, as desired, which could materially affect our business, financial condition and results of operations.

50Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates.

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates.*

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of private and public equity financings, debt financings, collaborations, strategic alliances and licensing arrangements. The sale of additional equity or convertible debt securities would dilute all of our stockholders and the terms of these securities may include liquidation or other preferences that adversely affect the rights of other stockholders. The incurrence of indebtedness would result in increased fixed payment obligations, and we may be required to agree to certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights, limitations on declaring dividends, limitations on our ability to redeem our shares and other operating restrictions that could adversely impact our ability to conduct our business. We could also be required to seek funds through collaborations, strategic alliances or licensing arrangements with third parties, and we could be required to do so at an earlier stage than otherwise would be desirable. In connection with any such collaborations, strategic alliances or licensing arrangements, we may be required to relinquish valuable rights to our intellectual property, future revenue streams, research programs or product candidates, grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves, or otherwise agree to terms unfavorable to us, any of which may have a material adverse effect on our business, operating results and prospects.

Risks Related to Development of Our Product Candidates

Commencing clinical trials in the United States is subject to acceptance by the FDA of an Investigational New Drug Application, (“or IND”), with respect to each product candidate in each indication, and finalizing the trial design based on discussions with the FDA. ~~For example, we will need to obtain an IND prior to commencing our planned clinical trials of inebilizumab in myasthenia gravis and IgG4-related diseases.~~ In the event that the FDA requires us to complete additional pre-clinical studies or we are required to satisfy other FDA requests, the start of our planned future clinical trials in the United States may be delayed. In particular, the FDA has not yet acknowledged IgG4-related diseases as an indication. ~~Our ability to commence our planned clinical trial in this target indication is subject to the FDA acknowledging it as a recognized indication.~~

We have three product candidates in various stages of clinical development and two product candidates in the pre-clinical development stage. We may not be able to demonstrate that they are safe or effective in the indications for which we are studying them, and they may not be approved. WeOn ~~submitted a BLA to the FDA for inebilizumab in~~ June ~~2019, which the FDA accepted for review in August 2019. The FDA set a PDUFA date of June~~ 11, 2020~~.

Other than the BLA for inebilizumab in patients with NMOSD that we submitted to the FDA in June 2019, which the FDA accepted for review in August 2019, we have not submitted, and we may never submit, marketing applications to the FDA or comparable foreign regulatory authorities for our product candidates. We cannot be certain that any of our product candidates will be successful in clinical trials or receive regulatory approval. Further, our product candidates may not receive regulatory approval even if they are successful in clinical trials and we do submit marketing applications seeking regulatory authorization for their use. If we do not receive regulatory approvals for one or more of our product candidates, we may not be able to continue our operations. 56

51a Phase 2b trial for VIB4920 in Sjögren’s syndrome, which is designed as Phase 3-enabling, and initiated a separate Phase 2 trial for VIB4920 in kidney transplant rejection. In November 2020, we reported the final data from our phase 1b trial with VIB7734 in an oral presentation at the American College of Rheumatology Convergence 2020. We also have pre-clinical product candidates that will need to progress through IND-enabling studies prior to clinical development. We are not permitted to market or promote any of our product candidates before we receive regulatory approval from the FDA or comparable foreign regulatory authorities, and we may never receive such regulatory approval for any of our product candidates

Other than the BLA for inebilizumab in patients with NMOSD that we submitted to the FDA in June 2019, which the FDA accepted for review in August 2019 and approved for the treatment of adult patients with NMOSD who are anti-AQP4 antibody positive as a twice-a-year maintenance regimen following initial doses, we have submitted a BLA in Europe, and our collaborators have submitted BLAs in Japan, Korea, and China. We may never submit marketing applications to the FDA or comparable foreign regulatory authorities for our product candidates. We cannot be certain that any of our product candidates will be successful in clinical trials or receive regulatory approval. Further, our product candidates may not receive regulatory approval even if they are successful in clinical trials and we do submit marketing applications seeking regulatory authorization for their use. If we do not receive regulatory approvals for one or more of our product candidates, we may not be able to continue our operations.

For each product candidate, we must demonstrate its safety and efficacy in humans, obtain regulatory approval in one or more jurisdictions, obtain manufacturing supply, capacity and expertise, and substantially invest in marketing efforts before we are able to generate any revenue from such product candidate. The success of our product candidates will depend on several factors, including the following:

• approval by the FDA of a BLA for inebilizumab;

•

submission to, and acceptance by, the FDA of an IND and of clinical trial applications to foreign governmental authorities, for our product candidates to commence planned clinical trials and future clinical trials;

•

successful enrollment in, and completion of, clinical trials, the design and implementation of which are agreed to by the applicable regulatory authorities, and the conduct of clinical trials by contract research organizations, or CROs, to successfully conduct such trials within our planned budget and timing parameters and without materially adversely impacting our trials;

•

successful data from our clinical programs that support an acceptable risk-benefit profile of our product candidates for the targeted indications in the intended populations to the satisfaction of the applicable regulatory authorities;

•

timely receipt, if at all, of regulatory approvals from applicable regulatory authorities;

•

establishment of arrangements with third-party manufacturers, as applicable, for continued clinical supply and commercial manufacturing;

•

successful development of our manufacturing processes and transfer to new third-party facilities to support future development activities and commercialization that are operated by contract manufacturing organizations, or CMOs, in a manner compliant with all regulatory requirements;

•

establishment and maintenance of patent and trade secret protection or regulatory exclusivity for our product candidates;

•

successful commercial launch of our product candidates, if and when approved;

•

acceptance of our products, if and when approved, by patients, the relevant medical communities and third-party payors;

•

effective competition with other therapies;

•

establishment and maintenance of adequate healthcare coverage and reimbursement;

•

our ability to avoid infringing upon the patent and other intellectual property rights of third parties;

•

enforcement and defense of intellectual property rights and claims;

•

continued compliance with any post-marketing requirements imposed by regulatory authorities, including any required post-marketing clinical trials or the elements of any post-marketing Risk Evaluation and Mitigation Strategy, or REMS, that may be required by the FDA or comparable requirements in other jurisdictions to ensure the benefits of the product outweigh its risks; and

•

maintenance of a continued acceptable safety profile of the product candidates following approval.

If we are unable to address one or more of these factors in a timely manner or at all, we could experience significant delays in the successful commercialization of, or an inability to successfully commercialize, our product candidates, which would materially harm our business. If we do not receive regulatory approvals for one or more of our product candidates, we may not be able to continue our operations. Even if we successfully obtain regulatory approvals to manufacture and market our product candidates, our revenues will be dependent, in part, upon the size of the markets in the territories for which we gain regulatory approval and have commercial rights. If the markets for patient subsets that we are targeting are not as significant as we estimate, we may not generate significant revenues from sales of such products, if approved.

WeSimilar to Uplizna®, we plan to seek regulatory approval to commercialize our product candidates in the United States and potentially in foreign countries. While the scope of regulatory approval is similar in many countries, to obtain separate regulatory approval in multiple countries we will be required to comply with numerous and varying regulatory requirements of each such country or jurisdiction regarding safety and efficacy and governing, among other things, clinical trials and commercial sales, pricing and distribution, and we cannot predict success in any such jurisdictions. The time required to obtain approval in foreign countries may differ substantially from that required to obtain FDA approval.

The risk of failure in drug development is high. ~~All~~The FDA approved Uplizna® (inebilizumab-cdon) for the treatment of ~~our~~adult ~~product~~patients ~~candidates~~with NMOSD who are inanti-AQP4 ~~clinical~~antibody ~~and~~positive ~~pre~~as a twice-~~clinical~~a-year ~~development,~~maintenance ~~and~~regimen wefollowing ~~have~~initial ~~never~~doses. ~~received~~All ~~marketing~~our ~~approval~~remaining product candidates are in ~~any~~clinical ~~jurisdiction~~and orpre-clinical ~~country~~development. Before obtaining marketing approval from regulatory authorities for the sale of any product candidate, we must complete nonclinical development and conduct extensive clinical trials to demonstrate the safety and efficacy of our product candidates in humans. Clinical trials are expensive, difficult to design and implement and can take several years to complete, and their outcomes are inherently uncertain. Failure can occur at any time during the clinical trial process. Nonclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in nonclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their products. While we believe the results of our pivotal trial of inebilizumab for the treatment of patients with NMOSD are positive, the FDA or a comparable foreign regulatory authority may disagree and may conclude that the results of our pivotal trial are not sufficient to approve inebilizumab. It is impossible to predict when or if any of our product candidates will prove to be effective or safe in humans or will receive marketing approval.

We may experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent our ability to receive marketing approval or commercialize our product candidates. Clinical trials may be delayed, suspended or prematurely terminated because costs are greater than we anticipate or for a variety of other reasons, such as:

•

delay or failure in reaching agreement with the FDA or a comparable foreign regulatory authority on a trial design that we are able to execute;

• delay or failure in obtaining authorization to commence a trial, including approval from the appropriate Institutional Review Board, (“or IRB”), to conduct testing of a candidate on human subjects, or inability to comply with conditions imposed by a regulatory authority regarding the scope or design of a clinical trial;

•

delays in reaching, or failure to reach, agreement on acceptable terms with prospective trial sites and prospective CROs, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;

•

inability, delay or failure in identifying and maintaining a sufficient number of trial sites, many of which may already be engaged in other clinical programs;

•

delay or failure in recruiting and enrolling suitable subjects to participate in a trial;

•

delay or failure in having subjects complete a trial or return for post-treatment follow-up;

•

clinical sites and investigators deviating from the clinical protocol, failing to conduct the trial in accordance with regulatory requirements, or dropping out of a trial;

•

failure to initiate or delay of or inability to complete a clinical trial as a result of the authorizing IND or clinical trial agreement being placed on clinical hold by the FDA or comparable foreign regulatory authority;

•

lack of adequate funding to continue a clinical trial, including unforeseen costs due to enrollment delays, requirements to conduct additional clinical trials and increased expenses associated with the services of our CROs and other third parties;

•

clinical trials of our product candidates may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional nonclinical studies, clinical trials or abandon product development programs;

•

the number of patients required for clinical trials of our product candidates may be larger than we anticipate, enrollment in these clinical trials may be slower than we anticipate or participants may drop out of these clinical trials at a higher rate than we anticipate;

•

our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all;

•

regulators, the IRB or a Data Safety Monitoring Board, or DSMB, if one is used for our clinical trials, may require that we suspend or terminate our clinical trials for various reasons, including noncompliance with regulatory requirements, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, or a finding that the participants are being exposed to unacceptable health risks;

•

the supply or quality of our product candidates or other materials necessary to conduct clinical trials of our product candidates may be insufficient;

•

the FDA or comparable foreign regulatory authorities may require us to submit additional data or impose other requirements before permitting us to initiate a clinical trial; or

•

changes in governmental regulations or administrative actions.

Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of marketing approval for our product candidates. Further, the FDA or comparable foreign regulatory authorities may disagree with our clinical trial design and our interpretation of data from clinical trials, or may change the requirements for approval even after it has reviewed and commented on the design for our clinical trials.

If we are required to conduct additional clinical trials or other nonclinical studies of our product candidates beyond those that we currently contemplate, if we are unable to successfully complete clinical trials of our product candidates or other studies, if the results of these trials or tests are not positive or are only modestly positive or if there are safety concerns, we may:

•

be delayed in obtaining marketing approval for our product candidates;

•

not obtain marketing approval for our product candidates at all;

•

obtain approval for indications or patient populations that are not as broad as intended or desired;

•

obtain approval with labeling that includes significant use or distribution restrictions or safety warnings that would reduce the potential market for our products or inhibit our ability to successfully commercialize our products;

•

be subject to additional post-marketing restrictions and/or requirements, including post-marketing testing; or

•

have the product removed from the market after obtaining marketing approval.

We cannot be certain as to what type and how many clinical trials the FDA or comparable foreign regulatory authorities will require us to conduct before we may successfully gain approval to market inebilizumab. Prior to approving a new product, the FDA generally requires that the efficacy of the product be demonstrated in two adequate and well-controlled clinical trials. In some situations, the FDA approves products on the basis of a single well-controlled clinical trial. ~~Based on our discussions with the FDA and the EMA, we conducted only a single pivotal trial of inebilizumab for the treatment of patients with NMOSD.~~ However, if the FDA or EMA determines that our pivotal trial results do not demonstrate a clinically meaningful benefit and an acceptable safety profile, or if the FDA or EMA requires us to conduct additional pivotal trials of ~~inebilizumab~~our product candidates in order to gain approval, we will incur significant additional development costs, commercialization of ~~inebilizumab~~our product candidates would be prevented or delayed and our business would be adversely affected.

Our product development costs will also increase if we experience delays in nonclinical and clinical development or receiving the requisite marketing approvals. We do not know whether any of our nonclinical studies or clinical trials will need to be restructured or will be completed on schedule, or at all. Significant nonclinical or clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our product candidates or allow our competitors to bring products to market before we do and impair our ability to successfully commercialize our product candidates and may harm our business and results of operations.

We may not be able to initiate or continue clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA or comparable foreign regulatory authorities. Patient enrollment is a significant factor in the timing of clinical trials. In particular, because certain of our clinical trials are focused on indications with small patient populations, our ability to enroll eligible patients may be limited or may result in slower enrollment than we anticipate. For example, based on an estimated prevalence of myasthenia gravis of 20 per 100,000 in the United States, we estimate the patient population to be approximately 56,000 and based on an estimated prevalence of systemic sclerosis of 13.5 to 44.3 per 100,000 in Europe and North America, we estimate the patient population to be approximately 300,000.

For example, based on an estimated prevalence of myasthenia gravis of 20 per 100,000 in the United States, we estimate the patient population to be approximately 56,000 and based on an estimated prevalence of systemic sclerosis of 13.5 to 44.3 per 100,000 in Europe and North America, we estimate the patient population to be approximately 300,000.

Patient enrollment may be affected if our competitors have ongoing clinical trials for product candidates that are under development for the same indications as our product candidates, and patients who would otherwise be eligible for our clinical trials instead enroll in clinical trials of our competitors’ product candidates. Patient enrollment may also be affected by other factors, including:

•

size and nature of the patient population;

•

severity of the disease under investigation;

•

patient eligibility criteria for the trial in question;

•

nature of the trial protocol;

•

our ability to recruit clinical trial investigators with the appropriate competencies and experience;

•

perceived risks and benefits of the product candidate under study;

•

the occurrence of adverse events attributable to our product candidates;

•

efforts to facilitate timely enrollment in clinical trials;

•

the number and nature of competing products or product candidates and ongoing clinical trials of competing product candidates for the same indication;

•

patient referral practices of physicians;

•

the ability to monitor patients adequately during and after treatment;

•

proximity and availability of clinical trial sites for prospective patients; and

•

continued enrollment of prospective patients by clinical trial sites.

If we experience delays or difficulties in the enrollment of patients in clinical trials, our clinical trials may be delayed or terminated. Any delays in completing our clinical trials will increase our costs, delay or prevent our product candidate development and approval process and jeopardize our ability to commence product sales and generate revenue. Any of these occurrences may harm our business, financial condition and prospects significantly.

~~We currently have no products approved for sale and we cannot guarantee that we will ever have marketable products.~~ Clinical failure can occur at any stage of clinical development. Clinical trials may produce negative or inconclusive results, and we or any future collaborators may decide, or regulators may require us, to conduct additional clinical trials or pre-clinical studies. We will be required to demonstrate with substantial evidence through well-controlled clinical trials that our product candidates are safe and effective for use in a diverse population before we can seek marketing approvals for their commercial sale. Success in pre-clinical studies and early-stage clinical trials does not mean that future larger registration clinical trials will be successful. This is because product candidates in later-stage clinical trials may fail to demonstrate sufficient safety and efficacy to the satisfaction of the FDA and comparable foreign regulatory authorities despite having progressed through pre-clinical studies and early-stage clinical trials. In particular, no compound with the mechanism of action of VIB4920 or VIB7734 has been commercialized, and the outcome of pre-clinical studies and early-stage clinical trials may not be predictive of the success of later-stage clinical trials.

From time to time, we may publish or report interim or preliminary data from our clinical trials. Interim or preliminary data from clinical trials that we may conduct may not be indicative of the final results of the trial and are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Interim or preliminary data also remain subject to audit and verification procedures that may result in the final data being materially different from the interim or preliminary data. As a result, interim or preliminary data should be viewed with caution until the final data are available.

In some instances, there can be significant variability in safety and efficacy results between different clinical trials of the same product candidate due to numerous factors, including changes in trial protocols, differences in size and type of the patient populations, differences in and adherence to the dosing regimen and other trial protocols and the rate of dropout among clinical trial participants. For example, in a Phase 1b trial, we observed that VIB4920 decreased disease activity in patients with rheumatoid arthritis. In 2019, we initiated a Phase 2 trial for VIB4920 in Sjögren’s syndrome and initiated a separate Phase 2 trial for VIB4920 in kidney transplant rejection. There is no assurance that VIB4920 will have a similar impact on disease activity in such planned Phase 2 trials.

activity in patients with rheumatoid arthritis. In 2019, we initiated a Phase 2b trial for VIB4920 in Sjögren’s syndrome and initiated a separate Phase 2 trial for VIB4920 in kidney transplant rejection. There is no assurance that VIB4920 will have a similar impact on disease activity in such Phase 2b and Phase 2 trials.

We do not know whether any clinical trials we may conduct will demonstrate consistent or adequate efficacy and safety sufficient to obtain marketing approval to market our product candidates.

55If we do not achieve our projected development and commercialization goals in the timeframes we announce and expect, the commercialization of Uplizna® or any additional product candidates, if approved, may be delayed, and our business will be harmed.

If we do not achieve our projected development and commercialization goals in the timeframes we announce and expect, the commercialization of inebilizumab or any additional product candidates may be delayed, and our business will be harmed.

For planning purposes, we sometimes estimate the timing of the accomplishment of various scientific, clinical, regulatory and other product development objectives. These milestones may include our expectations regarding the commencement or completion of scientific studies and clinical trials, the submission of regulatory filings, or commercialization objectives. From time-to-time, we may publicly announce the expected timing of some of these milestones, such as the completion of an ongoing clinical trial, the initiation of other clinical programs, receipt of marketing approval or a commercial launch of a product. The achievement of many of these milestones may be outside of our control. All of these milestones are based on a variety of assumptions which, if not realized as expected, may cause the timing of achievement of the milestones to vary considerably from our estimates, including:

•

our available capital resources or capital constraints we experience;

•

the rate of progress, costs and results of our clinical trials and research and development activities, including the extent of scheduling conflicts with participating clinicians and collaborators;

•

our ability to identify and enroll patients who meet clinical trial eligibility criteria;

•

our receipt of approvals by the FDA and other regulatory authorities and the timing thereof;

•

other actions, decisions or rules issued by regulators;

•

our ability to access sufficient, reliable and affordable supplies of materials used in the manufacture of our product candidates;

•

the efforts of our collaborators with respect to the commercialization of our products; and

•

the securing of, costs related to, and timing issues associated with, product manufacturing as well as sales and marketing activities.

If we fail to achieve announced milestones in the timeframes we expect, the commercialization ofand ~~inebilizumab~~clinical ~~and~~development of any ~~additional~~of our product candidates may be delayed, and our business and results of operations may be harmed.

Risks Related to Marketing Approval and Other Legal Compliance Matters

Our product candidates and the activities associated with their development and commercialization, including their design, testing, manufacture, safety, efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale, distribution, import and export are subject to comprehensive regulation by the FDA and other regulatory agencies in the United States and by comparable authorities in other countries. Before we can commercialize any of our product candidates, each such product candidate must be approved by regulatory authorities, such as the FDA pursuant to a BLA in the United States or in the EU by the EMA pursuant to a marketing authorization application, or MAA.

The process of obtaining marketing approvals, both in the United States and abroad, is expensive and takes several years, if approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the product candidates involved. Failure to obtain marketing approval for a product candidate will prevent us from commercializing the product candidate in the relevant market or country. We have not received approval to market any of our product candidates from regulatory authorities in any jurisdiction. We have limited experience in planning and conducting the clinical trials required for marketing approvals, and we have and expect to continue to rely on third-party CROs to assist us in this process. Obtaining marketing approval requires the submission of extensive nonclinical and clinical data and supporting information to regulatory authorities for each therapeutic indication to establish the product candidate’s safety and efficacy. Securing marketing approval also requires the submission of information about the product manufacturing process, and in many cases the inspection of manufacturing, processing, and packaging facilities by the regulatory authorities. Our product candidates may not be effective, may be only moderately effective or may prove to have undesirable or unintended side effects, toxicities or other characteristics that may preclude our obtaining marketing approval or prevent or limit commercial use, or there may be deficiencies in cGMP compliance by us or by our CMOs that could result in the candidate not being approved. Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that our data are insufficient for approval and require additional nonclinical studies or clinical trials. Inebilizumab for the treatment of NMOSD, or any of our other product candidates could be delayed in receiving, or fail to receive, marketing approval for many reasons, including the following: 61

Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that our data are insufficient for approval and require additional nonclinical studies or clinical trials. Our product candidates could be delayed in receiving, or fail to receive, marketing approval for many reasons, including the following:

•

the FDA or comparable foreign regulatory authorities may disagree with the design or implementation of our clinical trials;

•

we may be unable to demonstrate to the satisfaction of the FDA or comparable foreign regulatory authorities that a product candidate is safe and effective for its proposed indication;

•

the results of clinical trials may not meet the level of statistical significance required by the FDA or comparable foreign regulatory authorities for approval;

•

we may be unable to demonstrate that a product candidate’s clinical and other benefits outweigh its safety risks;

•

the FDA or comparable foreign regulatory authorities may disagree with our interpretation of data from nonclinical studies or clinical trials;

•

the data collected from clinical trials of our product candidates may not be sufficient to support the acceptance for review of a BLA or other submission to obtain marketing approval in the United States or elsewhere;

•

upon review of our clinical trial sites and data, the FDA or comparable foreign regulatory authorities may find our record keeping or the record keeping of our clinical trial sites to be inadequate;

•

third-party manufacturers or our clinical or commercial product candidates may be unable to meet the FDA’s cGMP requirements or similar requirements of foreign regulatory authorities; and

•

the approval policies or regulations of the FDA or comparable foreign regulatory authorities may significantly change in a manner rendering our clinical data insufficient for approval.

In addition, even if we were to obtain approval, regulatory authorities may approve any of our product candidates for fewer or more limited indications than we request, may grant approval contingent on the performance of costly post-marketing clinical trials (referred to as “conditional” or “accelerated” approval depending on the jurisdiction) or may approve a product candidate with prescribing information that does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate. Our clinical trials of inebilizumab have been designed for inebilizumab to be approved as a monotherapy that is dosed every six months, but there is no assurance that the FDA will agree that the data presented will be sufficient to approve inebilizumab with those dosing characteristics and we may need to conduct additional clinical trials if that were to occur. Any of the foregoing scenarios could materially harm the commercial prospects for our product candidates.

If we experience delays in obtaining approval or if we fail to obtain approval of our product candidates, the commercial prospects for our product candidates may be harmed and our ability to generate revenues will be materially impaired.

Undesirable side effects caused by our product candidates could cause us or the FDA or other regulatory authorities to interrupt, delay or halt our clinical trials and could result in a more restrictive label or the delay or denial of marketing approval by the FDA or other regulatory authorities of our product candidates. Results of our clinical trials could reveal a high and unacceptable severity and prevalence of side effects. In such an event, our trials could be suspended or terminated and the FDA or comparable foreign regulatory authorities could order us to cease further development of or deny approval of our product candidates for any or all targeted indications. In addition to this, the product-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. Any of these occurrences may harm our business, financial condition and prospects significantly.

All of our product candidates modulate the immune system and carry risks, including the theoretical risk of serious infections and cancer. Some common side effects of inebilizumab include urinary tract infection, arthralgia, back pain, headache, fall, hypoesthesia, cystitis and eye pain. Specifically, in our pivotal clinical trial for inebilizumab in patients with NMOSD, adverse events were reported in 71.8% (125/174) of the patients receiving inebilizumab in the randomized control period and 73.2% (41/56) of the patients receiving placebo in the randomized control period. In addition, two deaths have been reported in the ongoing open-label period. One death occurred in a patient experiencing a myelitis attack and was considered unrelated to inebilizumab by the investigator. The second death was due to complications from mechanical ventilator-associated pneumonia in a patient who developed new neurological symptoms and seizures, the cause of which could not be definitively established. The possibility that the death was treatment-related could not be ruled out, and as a result, under the terms of the protocol for the trial, the death was assessed as treatment-related. There can be no assurance that the FDA or comparable foreign regulatory authority will agree with the classifications of the deaths made by the investigators or that we will not be required to conduct additional clinical trials of inebilizumab in order to establish an adequate safety database. 62

57All of our product candidates modulate the immune system and carry risks, including the theoretical risk of serious infections and cancer. Across both the randomized and open-label treatment in our N-MOmentum trial for inebilizumab, the most common adverse reactions (greater than 10%) were urinary tract infection (20%), nasopharyngitis (13%), infusion reaction (12%), arthralgia (11%), and headache (10%). The most common infections reported by Uplizna® -treated patients in the randomized and open-label periods included urinary tract infection (20%), nasopharyngitis (13%), upper respiratory tract infection (8%), and influenza (7%). In addition, two deaths were reported in the ongoing open-label period. One death occurred in a patient experiencing a myelitis attack and was considered unrelated to inebilizumab by the investigator. The second death was due to complications from mechanical ventilator-associated pneumonia in a patient who developed new neurological symptoms and seizures, the cause of which could not be definitively established. The possibility that the death was treatment-related could not be ruled out, and as a result, under the terms of the protocol for the trial, the death was assessed as treatment-related. There can be no assurance a foreign regulatory authority will agree with the classifications of the deaths made by the investigators or that we will not be required to conduct additional clinical trials of inebilizumab in order to establish an adequate safety database.

Further, clinical trials by their nature utilize a sample of the potential patient population. With a limited number of patients, rare and severe side effects of our product candidates may only be uncovered with a significantly larger number of patients exposed to the product candidate. If our product candidates receive marketing approval and we or others identify undesirable side effects caused by such product candidates (or any other similar products) after such approval, a number of potentially significant negative consequences could result, including:

•

regulatory authorities may withdraw or limit their approval of such product candidates;

•

regulatory authorities may require the addition of labeling statements, such as a “boxed” warning or a contraindication;

•

we may be required to create a medication guide outlining the risks of such side effects for distribution to patients;

•

we may be required to change the way such product candidates are distributed or administered, or change the labeling of the product candidates;

•

FDA may require a REMS plan to mitigate risks, which could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools, and regulatory authorities in other jurisdictions may require comparable risk mitigation plans;

•

we may be subject to regulatory investigations and government enforcement actions;

•

the FDA or a comparable foreign regulatory authority may require us to conduct additional clinical trials or costly post-marketing testing and surveillance to monitor the safety and efficacy of the product;

•

we may decide to recall such product candidates from the marketplace after they are approved;

•

we could be sued and held liable for injury caused to individuals exposed to or taking our product candidates; and

•

our reputation may suffer.

We believe that any of these events could prevent us from achieving or maintaining market acceptance of the affected product candidates and could substantially increase the costs of commercializing our product candidates, if approved, and significantly impact our ability to successfully commercialize our product candidates and generate revenues.

A Breakthrough Therapy Designation by the FDA may not lead to a faster development or regulatory review or approval process, and does not increase the likelihood that our product candidates will receive marketing approval.

The FDA ~~recently~~ granted Breakthrough Therapy Designation to inebilizumab for the treatment of NMOSD, and we may seek such designation in the future for other product candidates. A Breakthrough Therapy is defined as a drug that is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. For drugs that have been designated as Breakthrough Therapies, interaction and communication between the FDA and the sponsor can help to identify the most efficient path for development. Drugs designated as Breakthrough Therapies are also eligible for accelerated approval.

FDA has discretion to determine whether the criteria for a Breakthrough Therapy has been met and whether to grant a Breakthrough Therapy Designation to an investigational product. Accordingly, even if we believe, after completing early clinical trials, that one of our product candidates meets the criteria for designation as a Breakthrough Therapy, the FDA may disagree and instead determine not to make such designation. In any event, the receipt of a Breakthrough Therapy Designation for a product candidate may not result in a faster development process, review or approval compared to product candidates considered for approval under conventional FDA procedures and does not assure ultimate approval by the FDA. In addition, even after granting Breakthrough Therapy Designation to our product candidates, the FDA may later decide that such product candidates no longer meet the conditions for qualification and withdraw such designation.

A Fast Track Designation by the FDA, even if granted for any of our product candidates, may not lead to a faster development or regulatory review or approval process and does not increase the likelihood that our product candidates will receive marketing approval.

We do not currently have Fast Track Designation for any of our product candidates, but may seek such designation in the future. If a drug is intended for the treatment of a serious or life-threatening condition and the drug demonstrates the potential to address unmet medical needs for this condition, the drug sponsor may apply for FDA Fast Track Designation. The FDA has broad discretion whether to grant this designation. Even if we believe a particular product candidate is eligible for this designation, we cannot assure you that the FDA would decide to grant it. Even if we do receive Fast Track Designation, we may not experience a faster development process, review or approval compared to conventional FDA procedures. The FDA may withdraw Fast Track Designation if it believes that the designation is no longer supported by data from our clinical development program. Many drugs that have received Fast Track Designation have failed to obtain regulatory approval.

Any product candidate for which we obtain marketing approval will be subject to extensive post-marketing regulatory requirements and could be subject to post-marketing restrictions or withdrawal from the market, and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with our products, when and if any of them are approved.

If the FDA or a comparable foreign regulatory authority approves any of our product candidates, activities such as the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for the product will be subject to extensive and ongoing regulatory requirements. The FDA or a comparable foreign regulatory authority may also impose requirements for costly post-marketing nonclinical studies or clinical trials (often called “Phase 4 trials”) and post-marketing surveillance to monitor the safety or efficacy of the product. If we or a regulatory authority discover previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, production problems or issues with the facility where the product is manufactured or processed, such as product contamination or significant not-compliance with applicable cGMPs, a regulator may impose restrictions on that product, the manufacturing facility or us. If we or our third-party providers, including our CMOs, fail to comply fully with applicable regulations, then we may be required to initiate a recall or withdrawal of our products.

We must also comply with requirements concerning advertising and promotion for any of our product candidates for which we obtain marketing approval. Promotional communications with respect to prescription drugs and biologics are subject to a variety of legal and regulatory restrictions and must be consistent with the information in the product’s approved labeling. Thus, we will not be able to promote any products we develop for indications or uses for which they are not approved. The FDA closely regulates the post-approval marketing and promotion of drugs to ensure drugs are marketed only for the approved indications and in accordance with the provisions of the approved labeling. The FDA imposes stringent restrictions on manufacturers’ communications regarding use of their products, and if we promote our products beyond their approved indications, we may be subject to enforcement actions or prosecution arising from that off-label promotion. Violations of the Federal Food, Drug, and Cosmetic Act relating to the promotion of prescription drugs and biologics may lead to investigations alleging violations of federal and state healthcare fraud and abuse laws, as well as state consumer protection laws. Accordingly, towith the ~~extent we receive~~ marketing approval for ~~one or more of our product candidates~~Uplizna®, we and our CMOs and other third-party partners will continue to expend time, money and effort in all areas of regulatory compliance, including promotional and labeling compliance, manufacturing, production, product surveillance, and quality control. If we are not able to comply with post-approval regulatory requirements, we could have marketing approval for any of our products withdrawn by regulatory authorities and our ability to market any future products could be limited, which could adversely affect our ability to achieve or sustain profitability. Thus, the cost of compliance with post-approval regulations may have a negative effect on our operating results and financial condition.

In addition, later discovery of previously unknown adverse events or other problems with any of our approved products, manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may yield various results, including:

•

restrictions on such products, manufacturers or manufacturing processes;

•

restrictions on the labeling or marketing of a product;

•

restrictions on product distribution or use;

•

requirements to conduct post-marketing studies or clinical trials;

•

warning or untitled letters from the FDA or comparable notice of violations from foreign regulatory authorities;

•

withdrawal of the products from the market;

•

refusal to approve pending applications or supplements to approved applications that we submit;

•

recall of products;

•

fines, restitution or disgorgement of profits or revenues;

•

suspension or withdrawal of marketing approvals;

•

suspension of any of our ongoing clinical trials;

•

imposition of restrictions on our operations, including closing our contract manufacturers’ facilities;

•

refusal to permit the import or export of our products;

•

product seizure; or

•

injunctions or the imposition of civil or criminal penalties.

Non-compliance with European Union and other jurisdiction’s requirements regarding safety monitoring or pharmacovigilance can also result in significant financial penalties. Similarly, failure to comply with the European Union’s and other jurisdiction’s requirements regarding the protection of personal information can also lead to significant penalties and sanctions.

The FDA’s policies may change and additional government regulations may be enacted that could prevent, limit or delay marketing approval of our product candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained, which would adversely affect our business, prospects and ability to achieve or sustain profitability.

Our relationships with prescribers, purchasers, third-party payors and patients will be subject to applicable anti-kickback, fraud and abuse and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.

~~Although~~With ~~we do not currently have any products on~~ the ~~market,~~approval ~~upon commercialization~~ of ~~our product candidates~~Uplizna®, ~~if approved,~~ we ~~will~~are be subject to additional healthcare statutory and regulatory requirements and oversight by federal and state governments as well as foreign governments in the jurisdictions in which we conduct our business. Physicians, other healthcare providers and third-party payors will play a primary role in the recommendation, prescription and use of any product candidates for which we obtain marketing approval. Our ~~future~~ arrangements with such third parties may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain our business or financial arrangements and relationships through which we market, sell and distribute any products for which we may obtain marketing approval. Restrictions under applicable domestic and foreign healthcare laws and regulations include the following:

•

the U.S. federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for, either the referral of an individual for, or the purchase, order or recommendation of, any good or service, for which payment may be made under a federal healthcare program such as Medicare and Medicaid; a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;

•

U.S. federal false claims, false statements and civil monetary penalties laws, including the U.S. False Claims Act, which impose criminal and civil penalties against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government; actions may be brought by the government or a whistleblower and may include an assertion that a claim for payment by federal healthcare programs for items and services which results from a violation of the federal Anti-Kickback Statue constitutes a false or fraudulent claim for purposes of the False Claims Act;

•

the U.S. federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, that imposes criminal and civil liability for executing a scheme to defraud any healthcare benefit program, or knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services; similar to the U.S. federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;

•

analogous state and foreign laws and regulations relating to healthcare fraud and abuse, such as state anti-kickback and false claims laws, that may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers;

•

the U.S. federal physician payment transparency requirements, sometimes referred to as the “Sunshine Act,” which requires manufacturers of drugs, devices, biologics and medical supplies that are reimbursable under Medicare, Medicaid, or the Children’s Health Insurance Program to report to the Centers for Medicare & Medicaid Services, or CMS, information related to physician payments and other transfers of value to physicians and teaching hospitals (and, beginning in 2021, for transfers of value to other healthcare providers), as well as the ownership and investment interests of physicians and their immediate family members;

•

analogous state and foreign laws that require pharmaceutical companies to track, report and disclose to the government and/or the public information related to payments, gifts, and other transfers of value or remuneration to physicians and other healthcare providers, marketing activities or expenditures, or product pricing or transparency information, or that require pharmaceutical companies to implement compliance programs that meet certain standards or to restrict or limit interactions between pharmaceutical manufacturers and members of the healthcare industry;

•

the U.S. federal laws that require pharmaceutical manufacturers to report certain calculated product prices to the government or provide certain discounts or rebates to government authorities or private entities, often as a condition of reimbursement under federal healthcare programs;

•

HIPAA, which imposes obligations on certain covered entity healthcare providers, health plans, and healthcare clearinghouses as well as their business associates that perform certain services involving the use or disclosure of individually identifiable health information, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information; and

•

state and foreign laws that govern the privacy and security of health information in certain circumstances, including state security breach notification laws, state health information privacy laws and federal and state consumer protection laws, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. IfWith the approval of Uplizna® by FDA, orwe aare ~~comparable~~subject ~~foreign~~to ~~regulatory~~an ~~authority~~expanded ~~approves~~number of these laws and regulations and will need to expend resources to develop and implement policies and processes to promote ongoing compliance. If inebilizumab or any of our other product candidates are approved by comparable foreign regulatory authorities, we ~~will~~ be subject to an expanded number of these laws and regulations and will need to expend resources to develop and implement policies and processes to promote ongoing compliance. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations, resulting in government enforcement actions.

If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, imprisonment, exclusion of products from federal healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations. If any of the physicians or other healthcare providers or entities with whom we expect to do business is found to be not in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from federal healthcare programs.

We may face difficulties from changes to current regulations and future legislation.

Existing regulatory policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability.

In the United States, there have been and continue to be a number of significant legislative initiatives to contain healthcare costs. Federal and state governments continue to propose and pass legislation designed to reform delivery of, or payment for, healthcare, which include initiatives to reduce the cost of healthcare. For example, in March 2010, the United States Congress enacted the Patient Protection and Affordable Care Act and the Healthcare and Education Reconciliation Act, or the ACA, which expanded healthcare coverage through Medicaid expansion and the implementation of the individual mandate for health insurance coverage and which included changes to the coverage and reimbursement of drug products under federal healthcare programs. The ACA contains a number of provisions that affect coverage and reimbursement of drug products and/or that could potentially reduce the demand for pharmaceutical products such as increasing drug rebates under state Medicaid programs for brand name prescription drugs and extending those rebates to Medicaid managed care and assessing a fee on manufacturers and importers of brand name prescription drugs reimbursed under certain government programs, including Medicare and Medicaid. Under the Trump administration, there have been ongoing efforts to modify or repeal all or certain provisions of the ACA. For example, tax reform legislation was enacted at the end of 2017 that eliminates the tax penalty established under the ACA for individuals who do not maintain mandated health insurance coverage beginning in 2019. In a May 2018 report, the Congressional Budget Office estimated

For example, in March 2010, the United States Congress enacted the Patient Protection and Affordable Care Act and the Healthcare and Education Reconciliation Act, or the ACA, which expanded healthcare coverage through Medicaid expansion and the implementation of the individual mandate for health insurance coverage and which included changes to the coverage and reimbursement of drug products under federal healthcare programs.

Under the Trump administration, there have been ongoing efforts to modify or repeal all or certain provisions of the ACA. For example, tax reform legislation was enacted at the end of 2017 that eliminates the tax penalty established under the ACA for individuals who do not maintain mandated health insurance coverage beginning in 2019. In a May 2018 report, the Congressional Budget Office estimated that, compared to 2018, the number of uninsured individuals in the United States will increase by three million in 2019 and six million in 2028, in part due to the elimination of the individual mandate. The ACA has also been subject to judicial challenge. In December 2018, a federal district court, in a challenge brought by a number of state attorneys general, found the ACA unconstitutional in its entirety because, once Congress repealed the individual mandate provision, there was no longer a basis to rely on Congressional taxing authority to support enactment of the law. Pending appeals, which could take some time, the ACA is still operational in all respects.

Additional legislative actions to control U.S. healthcare or other costs have passed. The Budget Control Act, as amended, resulted in the imposition of 2% reductions in Medicare (but not Medicaid) payments to providers in 2013 and will remain in effect through 2027 unless additional Congressional action is taken.

Recently, there has been considerable public and government scrutiny in the United States of pharmaceutical pricing and proposals to address the perceived high cost of pharmaceuticals. The ~~current~~Trump ~~presidential~~ administration has indicated an intent to address prescription drug pricing and recent Congressional hearings have brought increased public attention to the costs of prescription drugs and biologics. ~~State~~The Trump administration has made proposals, which, if implemented, could place limits or caps on pharmaceutical prices. Similarly, state governments also have sought to put in place limits and caps on pharmaceutical prices and have also requested rebates for certain pharmaceutical products. Whether any or all of these proposals will be implemented is uncertain.

We expect that current or future healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for any approved product. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our product candidates.

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for biotechnology products. We cannot be sure whether additional legislative changes will be enacted, or whether FDA regulations, guidance or interpretations for biological products will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if any, may be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval and decision-making processes may significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements.

Inadequate funding for the FDA, the SEC and other government agencies could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business.*

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, the ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory and policy changes. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of the SEC and other government agencies on which our operations may rely, including those that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable.

Disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, in our operations as a public company, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Our future growth may depend, in part, on our ability to penetrate foreign markets, where we would be subject to additional regulatory burdens and other risks and uncertainties.* 67

62Our future profitability may depend, in part, on our ability to commercialize our product candidates in foreign markets. In order to market and sell products in the European Union and many other jurisdictions, separate marketing approvals must be obtained and numerous and varying regulatory requirements must be complied with.

Additionally, a failure or delay in obtaining marketing approval in one jurisdiction may have a negative effect on the marketing approval process in others. Obtaining foreign marketing approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and costs could delay or prevent the introduction of products in certain countries. Failure to comply with the regulatory requirements in international markets and/or receive applicable marketing approvals, will result in the reduced ability to realize the full market potential of product candidates.

approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and costs could delay or prevent the introduction of products in certain countries. Failure to comply with the regulatory requirements in international markets and/or receive applicable marketing approvals, will result in the reduced ability to realize the full market potential of product candidates.

We may not be able to file for marketing approvals and may not receive necessary approvals to commercialize our products in any foreign market. If we obtain approval of our product candidates and ultimately commercialize our product candidates in foreign markets, we would be subject to additional risks and uncertainties, including:

•

our customers’ ability to obtain reimbursement for our product candidates in foreign markets;

•

our inability to directly control commercial activities because we are relying on third parties;

•

the burden of complying with complex and changing foreign regulatory, tax, accounting and legal requirements;

•

different medical practices and customs in foreign countries affecting acceptance in the marketplace;

•

import or export licensing requirements;

•

longer accounts receivable collection times;

•

longer lead times for shipping;

•

language barriers for technical training;

•

reduced protection of intellectual property rights in some foreign countries;

•

the existence of additional potentially relevant third-party intellectual property rights;

•

foreign currency exchange rate fluctuations; and

•

the interpretation of contractual provisions governed by foreign laws in the event of a contract dispute.

Foreign sales of our product candidates could also be adversely affected by the imposition of governmental controls, political and economic instability, trade restrictions and tariffs. In order to access certain foreign markets we anticipate entering into collaborations with third parties to develop and obtain certain products. For example, in May 2019, we entered into a collaboration agreement with Hansoh Pharmaceutical Group, or Hansoh Pharma, to co-develop and market inebilizumab in China, Hong Kong and Macau, and in October 2019, we entered into a license agreement with Mitsubishi Tanabe Pharma Corporation, or MTPC, for co-development and commercialization of inebilizumab in Japan, Thailand, South Korea, Indonesia, Vietnam, Malaysia, Philippines, Singapore, and Taiwan.

In many activities, including the conduct of clinical trials, we are subject to laws and regulations governing data privacy and the protection of health-related and other personal information. These laws and regulations govern our processing of personal data, including the collection, access, use, analysis, modification, storage, transfer, security breach notification, destruction and disposal of personal data.

The privacy and security of personally identifiable information stored, maintained, received or transmitted, including electronically, is subject to significant regulation in the United States and abroad. While we strive to comply with all applicable privacy and security laws and regulations, legal standards for privacy continue to evolve and any failure or perceived failure to comply may result in proceedings or actions against us by government entities or others, or could cause reputational harm, which could have a material adverse effect on our business.

Numerous foreign, federal and state laws and regulations govern collection, dissemination, use and confidentiality of personally identifiable health information, including state privacy and confidentiality laws (including state laws requiring disclosure of breaches), federal and state consumer protection and employment laws; HIPAA and European and other foreign data protection laws. These laws and regulations are increasing in complexity and number and may change frequently and sometimes conflict. The European Union’s omnibus data protection law, the General Data Protection Regulation, or GDPR, took effect on May 25, 2018. GDPR imposes numerous requirements on entities that process personal data in the context of an establishment in the European Economic Area, or EEA, or that process the personal data of data subjects who are located in the EEA. These requirements include, for example, establishing a basis for processing, providing notice to data subjects, developing procedures to vindicate expanded data subject rights, implementing appropriate technical and organizational measures to safeguard personal data, and complying with restrictions on the cross-border transfer of personal data from the EEA to countries that the European Union does not consider to have in place adequate data protection legislation, such as the United States. GDPR additionally establishes 68

HIPAA establishes a set of national privacy and security standards for the protection of individually identifiable health information, including protected health information, or PHI, by health plans, certain healthcare clearinghouses and healthcare providers that submit certain covered transactions electronically, or covered entities, and their “business associates,” which are persons or entities that perform certain services for, or on behalf of, a covered entity that involve creating, receiving, maintaining or transmitting PHI. While we are not currently a covered entity or business associate under HIPAA, we may receive identifiable information from these entities. Failure to receive this information properly could subject us to HIPAA’s criminal penalties, which may include fines up to $250,000 per violation and/or imprisonment. In addition, responding to government investigations regarding alleged violations of these and other laws and regulations, even if ultimately concluded with no findings of violations or no penalties imposed, can consume company resources and impact our business and, if public, harm our reputation.

In addition, various states, such as California and Massachusetts, have implemented similar privacy laws and regulations, such as the California Confidentiality of Medical Information Act, that impose restrictive requirements regulating the use and disclosure of health information and other personally identifiable information. In addition to fines and penalties imposed upon violators, some of these state laws also afford private rights of action to individuals who believe their personal information has been misused. California’s patient privacy laws, for example, provide for penalties of up to $250,000 and permit injured parties to sue for damages. The interplay of federal and state laws may be subject to varying interpretations by courts and government agencies, creating complex compliance issues for us and potentially exposing us to additional expense, adverse publicity and liability. Further, as regulatory focus on privacy issues continues to increase and laws and regulations concerning the protection of personal information expand and become more complex, these potential risks to our business could intensify.

The legislative and regulatory landscape for privacy and data security continues to evolve, and there has been an increasing focus on privacy and data security issues which may affect our business. Failure to comply with current and future laws and regulations could result in government enforcement actions (including the imposition of significant penalties), criminal and/or civil liability for us and our officers and directors, private litigation and/or adverse publicity that negatively affects our business.

In the United States, California recently adopted the California Consumer Privacy Act of 2018, or CCPA, which will come into effect beginning in January 2020. The CCPA has been characterized as the first “GDPR-like” privacy statute to be enacted in the United States because it mirrors a number of the key provisions of the EU General Data Protection Regulation. The CCPA establishes a new privacy framework for covered businesses in the State of California, by creating an expanded definition of personal information, establishing new data privacy rights for consumers imposing special rules on the collection of consumer data from minors, and creating a new and potentially severe statutory damages framework for violations of the CCPA and for businesses that fail to implement reasonable security procedures and practices to prevent data breaches.

64In some countries, particularly the countries of the European Union, Japan and China, the pricing of prescription pharmaceuticals is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidate to other available therapies. If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be harmed, possibly materially.

If we or our third-party contractors fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could harm our business.

We and our third-party contractors are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our operations and those of our third-party contractors involve the use of hazardous and flammable materials, including chemicals and biological materials. Our operations and those of our third-party contractors also produce hazardous waste products. We generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from the use of hazardous materials by us or our third-party service contractors, we could be held liable for any resulting damages, and the amount of the liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties for failure to comply with such laws and regulations.

Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against other potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological, hazardous or radioactive materials.

In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These current or future laws and regulations may impair our discovery, nonclinical development or production efforts. Our failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions.

Our business activities may be subject to the Foreign Corrupt Practices Act and similar anti-bribery and anti-corruption laws of other countries in which we operate.

We have conducted and have ongoing studies in international locations, and may in the future initiate additional studies in countries other than the United States. Our business activities may be subject to the Foreign Corrupt Practices Act, or FCPA, and similar anti-bribery or anti-corruption laws, regulations or rules of other countries in which we operate. The FCPA generally prohibits offering, promising, giving or authorizing others to give anything of value, either directly or indirectly, to a non-U.S. government official in order to influence official action or otherwise obtain or retain business. The FCPA also requires public companies to make and keep books and records that accurately and fairly reflect the transactions of the corporation and to devise and maintain an adequate system of internal accounting controls. Our business is heavily regulated and therefore involves significant interaction with public officials, including officials of non-U.S. governments. Additionally, in many other countries, the healthcare providers who prescribe pharmaceuticals are employed by their governments, and the purchasers of pharmaceuticals are government entities; therefore, our dealings with these prescribers and purchasers are subject to regulation under the FCPA. Recently the SEC and Department of Justice have increased their FCPA enforcement activities with respect to biotechnology and pharmaceutical companies. There is no certainty that all of our employees, agents or contractors, or those of our affiliates, will comply with all applicable laws and regulations, particularly given the high level of complexity of these laws. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees, the closing down of our facilities, requirements to obtain export licenses, cessation of business activities in sanctioned countries, implementation of compliance programs and prohibitions on the conduct of our business. Any such violations could include prohibitions on our ability to offer our products, if approved, in one or more countries and could materially damage our reputation, our brand, our international expansion efforts, our ability to attract and retain employees and our business, prospects, operating results and financial condition.

Biologics carry unique risks and uncertainties, which could have a negative impact on future results of operations.

The successful discovery, development, manufacturing and sale of biologics is a long, expensive and uncertain process. There are unique risks and uncertainties with biologics. For example, access to and supply of necessary biological materials, such as cell lines, may be limited and governmental regulations restrict access to and regulate the transport and use of such materials. In addition, the development, manufacturing and sale of biologics is subject to regulations that are often more complex and extensive than the regulations applicable to other pharmaceutical products. Manufacturing biologics, especially in large quantities, is often complex and may require the use of innovative technologies. Such manufacturing also requires facilities specifically designed and validated for this purpose and sophisticated quality assurance and quality control procedures. Biologics are also frequently costly to manufacture because production inputs are derived from living animal or plant material, and some biologics cannot be made synthetically. Failure to successfully discover, develop, manufacture and sell our biological product candidates would adversely impact our business and future results of operations.

Risks Related to Our Dependence on Third Parties

We are reliant on AstraZeneca for a period of time for certain services and for the clinical supplies of our product candidates and the commercial supplies of ~~inebilizumab~~Uplizna®.

We were incorporated in December 2017 and, in February 2018, we acquired six molecules from MedImmune. Following the assets purchase, we entered into several agreements with AstraZeneca and MedImmune, including a license agreement, sublicense agreements, a transition services agreement, a master supply and development services agreement, a clinical supply agreement and a commercial supply agreement. AstraZeneca has no obligation to assist our operations and growth strategy, other than providing certain services or rights pursuant to these agreements. Pursuant to the transition services agreement, we are, and for a period of time will be, reliant on AstraZeneca for certain services, including, but not limited to, financial services, procurement activities, information technology services, clinical data management and statistical programming, clinical operations and development and commercial activities. AstraZeneca is obligated to provide each of these services for a designated period of time ranging from several months to approximately five years, depending upon the nature of the service provided.

We are, and for a period of time will be, substantially reliant on AstraZeneca to provide these services, and if AstraZeneca is unable or unwilling to satisfy its obligations under these agreements, we could incur operational difficulties or losses that could have a material and adverse effect on our business, prospects, financial condition and results of operations.

Furthermore, the services provided by AstraZeneca under these agreements do not include every service that is necessary to successfully operate our business, and AstraZeneca is only obligated to provide these services for limited periods of time. Accordingly, we must develop internal capabilities to perform these services, or obtain from other third parties services we currently receive from AstraZeneca. If we are unable to efficiently implement our own systems and services, or if we are unable to negotiate agreements with third-party providers of these services in a timely manner or on terms and conditions as favorable as those we receive from AstraZeneca, we may not be able to operate our business effectively and our financial condition may decline. Furthermore, if we fail to develop high-quality internal capabilities from third-party providers, in a cost-effective manner, we may be unable to operate our existing business or execute our strategic priorities successfully and efficiently, and our operating results and financial condition may be materially harmed.

We do not have the ability to independently conduct clinical trials. We rely on and expect to continue to rely on medical institutions, clinical investigators, contract laboratories and other third parties, such as CROs, to conduct or otherwise support clinical trials for our product candidates. In addition, we rely on AstraZeneca for certain operational and regulatory services with respect to each of our product candidates and their clinical trials and pre-clinical studies.

We have and expect to continue to rely heavily on these parties to conduct clinical trials for our product candidates. Nevertheless, we will be responsible for ensuring that each of our clinical trials is conducted in accordance with the applicable protocol, legal and regulatory requirements and scientific standards.

We and our CROs will be required to comply with regulations, including good clinical practice, or GCP, and other related requirements for conducting, monitoring, recording and reporting the results of clinical trials to ensure that the data and results are scientifically credible and accurate, and that the trial patients are adequately informed of the potential risks of participating in clinical trials and their rights are protected. These regulations are enforced by the FDA, the Competent Authorities of the Member States of the EEA and comparable foreign regulatory authorities for any drugs in clinical development. The FDA and comparable foreign regulatory authorities enforce GCPs through periodic inspections of clinical trial sponsors, principal investigators and trial sites. If we or our CROs fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be called into question and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before considering our marketing applications for approval. We cannot assure you that, upon inspection, the FDA or a comparable foreign regulatory authority will determine that any of our future clinical trials will comply with GCPs. In addition, our clinical trials must be conducted with product candidates produced under cGMPs. Our failure or the failure of our CROs to comply with these regulations may require us to repeat clinical trials, which would delay the marketing approval process and could also subject us to enforcement action. We also are required to register certain clinical trials and post the results of such completed clinical trials involving product candidates for which we receive marketing approval on a government-sponsored database, www.ClinicalTrials.gov, within certain timeframes. Failure to do so can result in fines, adverse publicity and civil and criminal sanctions.

Failure to do so can result in fines, adverse publicity and civil and criminal sanctions.

Although we intend to design the clinical trials for our product candidates, CROs have administered and will continue to administer all of the clinical trials. As a result, many important aspects of our development programs, including their conduct and timing, will be outside of our direct control. Our reliance on third parties to conduct future clinical trials will also result in less direct control over the management of data developed through clinical trials than would be the case if we were relying entirely upon our own staff. Communicating with outside parties can also be challenging, potentially leading to mistakes as well as difficulties in coordinating activities. Outside parties may:

•

have staffing difficulties;

•

fail to comply with contractual obligations;

•

experience regulatory compliance issues;

•

undergo changes in priorities or become financially distressed;

•

make errors in the design, management or retention of our data or data systems; and/or

•

form relationships with other entities, some of which may be our competitors.

These factors may materially adversely affect the willingness or ability of third parties to conduct our clinical trials and may subject us to unexpected cost increases that are beyond our control. If the CROs have not or do not conduct clinical trials in a satisfactory manner, breach their obligations to us or fail to comply with regulatory requirements, the development, marketing approval and commercialization of our product candidates may be delayed, we may not be able to obtain marketing approval and commercialize our product candidates, or our development program may be materially and irreversibly harmed. If we are unable to rely on clinical data collected by our CROs, we could be required to repeat, extend the duration of, or increase the size of any clinical trials we conduct and this could significantly delay commercialization and require significantly greater expenditures.

If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs. If CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, any clinical trials such CROs are associated with may be extended, delayed or terminated, and we may not be able to obtain marketing approval for or successfully commercialize our product candidates. As a result, we believe that our financial results and the commercial prospects for our product candidates in the subject indication would be harmed, our costs could increase and our ability to generate revenue could be delayed.

We do not currently own or operate, nor do we have any plans to establish in the future, any manufacturing facilities or personnel. We rely, and expect to continue to rely, on third parties for the manufacture of our product candidates for nonclinical studies and clinical trials, as well as for the commercial manufacture of ~~our approved products if any of our product candidates receives marketing approval~~Uplizna®. In particular, we rely on AstraZeneca for the manufacture of the current clinical and ~~potential future~~ commercial supplies of ~~inebilizumab~~Uplizna®, and for the current clinical and nonclinical supplies of our other product candidates. This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or approved products or such quantities at an acceptable cost or quality, which could delay, prevent or impair our development or commercialization efforts.

The facilities used to manufacture our product candidates must be evaluated by the FDA or a comparable foreign regulatory authority pursuant to inspections that will be conducted after we submit our marketing applications to the FDA to ensure compliance with cGMP. We do not control the manufacturing process of, and are completely dependent on, our contract manufacturers for compliance with cGMPs in connection with the manufacture of our product candidates. If AstraZeneca or other contract manufacturers we may engage in the future cannot successfully manufacture material that conforms to our specifications and the regulatory requirements of the FDA or a comparable foreign regulatory authority, we will not be able to use the product candidates or products produced at their manufacturing facilities. In addition, we have no control over the ability of AstraZeneca or other contract manufacturers we may engage in the future to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of our product candidates we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain marketing approval for or market our product candidates, if approved. Further, our failure, or the failure of AstraZeneca or other third party manufacturers we may engage in the future, to comply with applicable regulations could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates or products, if approved, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect our business and supplies of our product candidates.

We may be unable to establish any agreements with third-party manufacturers or to do so on acceptable terms. Even if we are able to establish agreements with third party manufacturers, reliance on third party manufacturers entails additional risks, including:

•

reliance on the third party for regulatory compliance and quality assurance;

•

the possible breach of the manufacturing agreement by the third party;

•

the possible misappropriation of our proprietary information, including our trade secrets and know-how; and

•

the possible termination or nonrenewal of the agreement by the third party at a time that is costly or inconvenient for us.

Our current and future product candidates may compete with other product candidates and approved products for access to manufacturing facilities. There are a limited number of manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us.

Any performance failure on the part of our existing or future manufacturers could delay clinical development or marketing approval. If our current contract manufacturers cannot perform as agreed, we may be required to replace such manufacturers. Although we believe that there are several potential alternative manufacturers who could manufacture our product candidates, we may incur added costs and delays in identifying and qualifying any such replacement. For example, AstraZeneca currently manufactures inebilizumab for us using their proprietary methods in certain steps of the manufacturing process. If we were to replace AstraZeneca for the manufacture of inebilizumab, we may incur additional costs and delays while the replacement manufacturer developed its own independent methods of manufacturing inebilizumab. Moreover, we would need to confirm that the drug product from the replacement manufacturer is comparable to the drug product that AstraZeneca is currently manufacturing for us.

Our current and anticipated future dependence upon others for the manufacture of our product candidates or products, if approved, may adversely affect our future profit margins and our ability to commercialize any products that receive marketing approval on a timely and competitive basis.

In order to conduct large-scale clinical trials of or commercialize our product candidates, we will need to manufacture them in large quantities. We, or any of our current or future manufacturing partners, including AstraZeneca, may be unable to successfully increase the manufacturing capacity for any of our product candidates in a timely or cost-effective manner, or at all. In addition, quality issues may arise during scale-up activities. Further, in order to release product and demonstrate stability of product candidates for use in late-stage clinical trials (and any subsequent products for commercial use), our analytical methods must be validated in accordance with regulatory guidelines. We may not be able to successfully validate, or maintain validation of, our analytical methods or demonstrate adequate purity, stability or comparability of the product candidates in a timely or cost-effective manner, or at all. For example, in connection with the potential commercialization of inebilizumab, AstraZeneca is in the process of scaling up and optimizing the manufacturing process for inebilizumab. While we believe the optimized manufacturing process meets all of the regulatory manufacturing requirements, the FDA will review the optimized process as part of the review of the BLA for inebilizumab. If we, or any current or future manufacturing partners, including AstraZeneca, are unable to successfully scale up the manufacture of our product candidates, ~~including inebilizumab,~~ in sufficient quality and quantity, or if we encounter validation issues, the development, testing and clinical trials of that product candidate, ~~including inebilizumab,~~ may be delayed or infeasible, and regulatory approval or commercial launch of any resulting product, ~~including inebilizumab,~~ may be delayed or not obtained, which could significantly harm our business.

Manufacturing biological products like our product candidates, especially in large quantities, is often complex and may require the use of innovative technologies to handle living microorganisms. Each lot of an approved biologic must undergo thorough testing for identity, strength, quality, purity and potency. Manufacturing biologics such as monoclonal antibodies and complex protein products requires facilities specifically designed for and validated for this purpose, and sophisticated quality assurance and quality control procedures are necessary. Slight deviations anywhere in the manufacturing process, including filling, labeling, packaging, storage and shipping and quality control and testing, may result in lot failures, product recalls or spoilage. When changes are made to the manufacturing process or any steps in the production and purification processes, we may be required to provide pre-clinical and clinical data showing the comparable identity, strength, quality, purity or potency of the products before and after such changes. Biologics are frequently more complex than chemical drugs to manufacture because production ingredients are derived from living animal or plant material, and most biologics cannot be made synthetically. Manufacturers of biological products often encounter difficulties in production, which include difficulties with production costs and yields, quality control and assurance and shortages of qualified personnel, as well as compliance with strictly enforced federal, state and foreign regulations.

encounter difficulties in production, which include difficulties with production costs and yields, quality control and assurance and shortages of qualified personnel, as well as compliance with strictly enforced federal, state and foreign regulations.

The source materials and cell cultures used to produce our product candidates are supplied to us from single-source suppliers with limited capacity. Our ability to successfully develop our product candidates, and to ultimately supply our commercial products, if approved in quantities sufficient to meet the market demand, depends in part on our ability to obtain the source materials and biological products in accordance with cGMP regulatory requirements and in sufficient quantities for commercialization and clinical trials. We do not currently have arrangements in place for a redundant or second-source supply of any source material or biological product in the event any of our current suppliers cease their operations for any reason.

We do not know whether our suppliers will be able to meet our demand, either because of the nature of our agreements with those suppliers, our limited experience with those suppliers or our relative importance as a customer to those suppliers. It may be difficult for us to assess their ability to timely meet our demand in the future based on past performance. While our suppliers have generally met our demand for their products on a timely basis in the past, they may subordinate our needs in the future to their other customers.

For some of our product candidates, we intend to identify and qualify additional contract manufacturers prior to submission of a BLA to the FDA and/or an MAA to the EMA. Establishing additional or replacement suppliers for our product candidates, if required, may not be accomplished quickly. If we are able to find a replacement supplier, such replacement supplier would need to be qualified and may require additional marketing approval, which could result in further delay. While we seek to maintain adequate inventory of the source materials, cell cultures and other components needed to produce our product candidates, any interruption or delay in the supply of components or materials, or our inability to obtain such materials from alternate sources at acceptable prices in a timely manner could impede, delay, limit or prevent our development efforts, which could harm our business, results of operations, financial condition and prospects.

We may seek to establish collaborations, and, if we are not able to establish them on commercially reasonable terms, we may have to alter our development and commercialization plans.*

Our product candidate development programs and the potential commercialization of our product candidates will require substantial additional cash to fund expenses. For some of our product candidates, we may decide to collaborate with pharmaceutical and biotechnology companies for the development and potential commercialization of those product candidates. In particular, we initially plan to seek partnerships to pursue regulatory approval and commercialization of our product candidates outside the United States. For example, in May 2019, we entered into a license and collaboration agreement with Hansoh Pharma to co-develop and market inebilizumab in China, Hong Kong and Macau, and in October 2019, we entered into a license agreement with MTPC for co-development and commercialization of inebilizumab in Japan, Thailand, South Korea, Indonesia, Vietnam, Malaysia, Philippines, Singapore, and Taiwan.

We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of approval by the FDA or comparable foreign regulatory authorities, the potential market for the subject product candidate, the costs and complexities of manufacturing and delivering such product candidate to patients, the potential of competing products and market conditions generally. The collaborator may also consider alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such a collaboration could be more attractive than the one with us for our product candidate. The terms of any collaborations or other arrangements that we may enter into may not be favorable to us.

We may also be restricted under existing or future collaboration agreements from entering into future agreements on certain terms with potential collaborators. Collaborations are complex and time-consuming to negotiate and document. In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators.

We may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the development of the product candidate for which we are seeking to collaborate, reduce or delay its development program or one or more of our other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidates or bring them to market and generate product revenue.

In addition, any collaboration that we enter into may not be successful. The success of our collaboration arrangements will depend heavily on the efforts and activities of our collaborators. Collaborators generally have significant discretion in determining the efforts and resources that they will apply to these collaborations. Any such collaboration may require us to incur non-recurring or other charges, increase our near- and long-term expenditures and pose significant integration or implementation challenges or disrupt our management or business. These transactions would entail numerous operational and financial risks, including exposure to unknown liabilities, disruption of our business and diversion of our management’s time and attention in order to manage a collaboration, incurrence of substantial debt or dilutive issuances of equity securities to pay transaction consideration or costs, higher than expected collaboration or integration costs, write-down of assets or goodwill or impairment charges, increased amortization expenses and difficulty and cost in facilitating the collaboration.

Lastly, disagreements between parties to a collaboration arrangement regarding clinical development and commercialization matters can lead to delays in the development process or commercializing the applicable product candidate and, in some cases, termination of the collaboration arrangement. These disagreements can be difficult to resolve if neither of the parties has final decision-making authority. Collaborations with pharmaceutical or biotechnology companies and other third parties often are terminated or allowed to expire by the other party. Any such termination or expiration would adversely affect us financially and could harm our business reputation.

Risks Related to the Commercialization of Our Product Candidates

~~Even~~Uplizna®, ifwhich received FDA approval in June 2020, or any of our product candidates ~~receives~~that receive marketing approval, itif any, may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success.

IfUplizna®, which received FDA approval in June 2020, or any of our product candidates ~~receives~~that receive marketing approval, itif any, may ~~nonetheless~~ fail to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical community. If Uplizna® or our product candidates, if approved, do not achieve an adequate level of acceptance, we may not generate significant product revenues and we may not become profitable. The degree of market acceptance of Uplizna® or our product candidates, if approved for commercial sale, will depend on a number of factors, including:

• the timing of our receipt of any marketing approvals for our product candidates;

•

the terms of any approvals and the countries in which approvals are obtained;

•

the efficacy and safety and potential advantages and disadvantages compared to alternative treatments, including future alternative treatments;

•

the prevalence and severity of any side effects associated with our product candidates;

•

the indications for which our products are approved and the scope of risk information required to be included in the product labeling;

•

adverse publicity about our products or favorable publicity about competing products;

•

the approval of other products for the same indications as our products;

•

our ability to offer our products for sale at competitive prices;

•

the convenience and ease of administration compared to alternative treatments;

•

the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;

•

the success of our physician education programs;

•

the strength of our marketing and distribution support;

•

the availability of third-party coverage and adequate reimbursement;

•

the extent of patient cost-sharing obligations, including copays and deductibles;

•

the availability of products and their ability to meet market demand, including a reliable supply for long-term treatment; and

•

any restrictions on the use of our products together with other medications.

If any product candidate we commercialize fails to achieve market acceptance, it could have a material and adverse effect on our business, financial condition, results of operation and prospects.

We face substantial competition, which may result in others discovering, developing or commercializing competing products before or more successfully than we do.

The development and commercialization of new drug products is highly competitive. We face competition with respect to our current product candidates, and expect to face competition with respect to any product candidates that we may seek to develop or commercialize in the future, from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. Potential competitors also include academic institutions, government agencies and other public and private research organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, manufacturing and commercialization.

Specifically, there are a number of companies developing or marketing treatments for autoimmune diseases, including many major pharmaceutical and biotechnology companies. IfUplizna®, ~~inebilizumab~~our is approved, itproduct ~~would~~for the treatment of patients with NMOSD, will compete with eculizumab from Alexion Pharmaceuticals, Inc., or Alexion, ~~to be~~ marketed as Soliris®, and satralizumab, marketed as EnspryingTM from Chugai Pharmaceuticals Co., Ltd., each for the treatment of patients with NMOSD. Both products have achieved successful pivotal studies in NMOSD and in June 2019, Alexion received FDA approval of Soliris® for the treatment of adults with NMOSD and in August 2020 Chugai received approval for EnspryingTM for the treatment of adults with NMOSD. If VIB4920 is approved, it would compete with: (a) if approved, dapirolizumab pegol, an investigational anti-CD40L pegylated Fab being developed in SLE jointly by UCB and Biogen, (b) Belatacept (NULOJIX®), a selective T cell costimulation blocker indicated for prophylaxis of organ rejection in adult patients receiving a kidney transplant, developed by Bristol-Myers Squib, (c) if approved, BI 655064, a humanized mouse anti-human mAb being developed in SLE as part of a global collaboration of AbbVie and Boehringer Ingelheim, (d) if approved, CFZ533, a mAb being developed in primary Sjögren’s syndrome by Novartis and (e) multiple approved drugs or drugs that may be approved in the future for indications for which we may develop VIB4920. If VIB7734 is approved, it would compete with: (a) if approved for lupus, BIIB059, a mAb targeting BDCA2, which is a protein present in specific cells within the immune system, being developed by Biogen, (b) if approved for systemic sclerosis, Nintedanib, a tyrosine kinase inhibitor being developed by Boehringer Ingelheim and (c) multiple approved drugs or drugs that may be approved in the future for indications for which we may develop VIB7734.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that we may develop. Our competitors also may obtain FDA or other marketing approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market and/or slow our marketing approval. For example, in June 2019 Alexion received FDA approval of Soliris® for the treatment of adults with NMOSD and in August 2020 Chugai received approval for EnspryingTM for the treatment of adults with NMOSD. Some of the important competitive factors affecting the success of all of our product candidates, if approved, are likely to be their efficacy, safety, convenience, price and the availability of reimbursement from government and other third-party payors.

Many of the companies against which we are competing or against which we may compete in the future have significantly greater financial resources and expertise in research and development, manufacturing, nonclinical studies, conducting clinical trials, obtaining marketing approvals and marketing approved products than we do. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller and early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

Our product candidates for which we intend to seek approval may face generic or biosimilar competition sooner than anticipated.

Even if we are successful in achieving regulatory approval to commercialize a product candidate ahead of our competitors, our product candidates may face competition from biosimilar products. In the United States, our product candidates are regulated by the FDA as biological products and we intend to seek approval for these product candidates pursuant to the BLA pathway. The Biologics Price Competition and Innovation Act of 2009, or BPCIA, created an abbreviated pathway for FDA approval of biosimilar and interchangeable biological products based on a previously licensed reference product. Under the BPCIA, an application for a biosimilar biological product cannot be approved by the FDA until 12 years after the original reference biological product was approved under a BLA. The law is complex and is still being interpreted and implemented by the FDA. As a result, its ultimate impact, implementation, and meaning are subject to uncertainty. While it is uncertain when such processes intended to implement BPCIA may be fully adopted by the FDA, any such processes could have a material adverse effect on the future commercial prospects for our product candidates.

We believe that any of our product candidates approved as a biological product under a BLA should qualify for the 12-year period of exclusivity available to reference biological products. However, there is a risk that this exclusivity could be shortened due to congressional action or otherwise, or that the FDA will not consider our product candidates to be reference biological products pursuant to its interpretation of the exclusivity provisions of the BPCIA for competing products, potentially creating the opportunity for generic follow-on biosimilar competition sooner than anticipated. Moreover, the extent to which a biosimilar product, once approved, will be substituted for any one of our reference products in a way that is similar to traditional generic substitution for non-biological products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing including whether a future competitor seeks an interchangeability designation for a biosimilar of one of our products. Under the BPCIA as well as state pharmacy laws, only interchangeable biosimilar products are considered substitutable for the reference biological product without the intervention of the health care provider who prescribed the original biological product. However, as with all prescribing decisions made in the context of a patient-provider relationship and a patient’s specific medical needs, healthcare providers are not restricted from prescribing biosimilar products in an off-label manner. In addition, a competitor could decide to forego the abbreviated approval pathway available for biosimilar products and to submit a full BLA for product licensure after completing its own preclinical studies and clinical trials. In such a situation, any exclusivity to which we may be eligible under the BPCIA would not prevent the competitor from marketing its biological product as soon as it is approved.

In such a situation, any exclusivity to which we may be eligible under the BPCIA would not prevent the competitor from marketing its biological product as soon as it is approved.

In Europe, the European Commission has granted marketing authorizations for several biosimilar products pursuant to a set of general and product class-specific guidelines for biosimilar approvals issued over the past few years. In addition, companies may be developing biosimilar products in other countries that could compete with our products, if approved.

If competitors are able to obtain marketing approval for biosimilars referencing our product candidates, if approved, our future products may become subject to competition from such biosimilars, whether or not they are designated as interchangeable, with the attendant competitive pressure and potential adverse consequences. Such competitive products may be able to immediately compete with us in each indication for which our product candidates may have received approval.

~~Even~~Uplizna®, ifas well as any product candidates that we are able to commercialize, ~~any~~if ~~product candidates~~any, ~~such products~~ may become subject to unfavorable pricing regulations or third-party coverage and reimbursement policies, which would harm our business.

The regulations that govern marketing approvals, pricing and reimbursement for new drugs vary widely from country to country. Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after marketing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain marketing approval for a product candidate in a particular country, but then be subject to price regulations that delay our commercial launch of the product candidate, possibly for lengthy time periods, and negatively impact the revenues we are able to generate from the sale of the product candidate in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more product candidates, even if our product candidates obtain marketing approval.

Our ability to commercialize any product candidates successfully also will depend in part on the extent to which coverage and reimbursement for these product candidates and related treatments will be available from government authorities, private health insurers and other organizations. In the United States, reimbursement varies from payor to payor. Reimbursement agencies in Europe may be more conservative than federal healthcare programs or private health plans in the U.S. For example, a number of cancer drugs are generally covered and paid for in the United States, but have not been approved for reimbursement in certain European countries. A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and third-party payors have attempted to control costs by limiting coverage and the amount of payments for particular products. For example, payors may limit coverage to specific drug products on an approved list, also known as a formulary, which might not include all of the FDA-approved drugs for a particular indication. Payors may require use of alternative therapies or a demonstration that a product is medically necessary for a particular patient before use of a product will be covered. Additionally, payors may seek to control utilization by imposing prior authorization requirements. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for products. We cannot be sure that coverage will be available for any product candidate that we commercialize and, if coverage is available, what the level of reimbursement will be. Reimbursement may impact the demand for, or the price of, any product candidate for which we obtain marketing approval. Patients are unlikely to use our or our partners’ products unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of such products. If reimbursement is not available or is available only to limited levels, we may not be able to successfully commercialize any product candidate for which we obtain marketing approval.

In addition to CMS and private payors, professional organizations such as the American Autoimmune Related Diseases Association, Inc. can influence decisions about reimbursement for new medicines by determining standards of care. In addition, many private payors contract with commercial vendors who sell software that provide guidelines that attempt to limit utilization of, and therefore reimbursement for, certain products deemed to provide limited benefit to existing alternatives. Such organizations may set guidelines that limit reimbursement or utilization of our products.

There may be significant delays in obtaining reimbursement for newly approved drugs and biologics, and coverage may be more limited than the purposes for which the drug is approved by the FDA or comparable foreign regulatory authorities. Moreover, eligibility for reimbursement does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim reimbursement levels for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost drugs and may be incorporated into existing payments for other services. Net prices for drugs may be reduced by discounts or rebates required by federal healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. Our inability to promptly obtain coverage and profitable payment rates from both government-funded and private payors for any approved products that we develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financial condition.

72We currently have a focused marketing and sales force. If we are unable to establish effective sales or marketing capabilities or enter into agreements with third parties to sell or market our product candidates, we may not be able to effectively sell or market our product candidates, if approved, or generate product revenues.

We currently have a limited marketing and sales force. If we are unable to establish effective sales or marketing capabilities or enter into agreements with third parties to sell or market our product candidates, we may not be able to effectively sell or market our product candidates, if approved, or generate product revenues.

We currently have a limited sales and marketing infrastructure. To achieve commercial success for any approved product candidate for which we retain sales and marketing responsibilities, we must build our sales, marketing, managerial, and other non-technical capabilities or make arrangements with third parties to perform these services. For example, we are currently exploring the use of sales representatives for the marketing of inebilizumab in patients with NMOSD in the United States, if approved. There are risks involved with both establishing our own sales and marketing capabilities and entering into arrangements with third parties to perform these services. For example, recruiting and training a sales force is expensive and time consuming and could delay any product launch. If the commercial launch of a product candidate for which we recruit a sales force and establish marketing capabilities is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses. This may be costly, and our investment would be lost if we cannot retain or reposition our sales and marketing personnel.

Factors that may inhibit our efforts to commercialize our product candidates on our own include:

•

our inability to recruit, hire, retain and incentivize adequate numbers of effective sales and marketing personnel;

•

the inability of sales personnel to obtain access to physicians or persuade adequate numbers of physicians to prescribe any future products;

•

the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies with more extensive product lines; and

•

unforeseen costs and expenses associated with establishing an independent sales and marketing organization.

If we enter into arrangements with third parties to perform sales, marketing and distribution services, as we are currently exploring for the marketing of inebilizumab in the United States, if approved, our product revenues or the profitability of these product revenues to us are likely to be lower than if we were to market and sell any product candidates that we develop ourselves. In addition, we may not be successful in entering into arrangements with third parties to sell and market inebilizumab or any of our other product candidates or may be unable to do so when needed or on terms that are favorable to us. We likely will have more limited control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our product candidates effectively, or they may fail to comply with promotional requirements for prescription products that could render our products misbranded in violation of FDA regulations and thus potentially subject to enforcement. If we do not establish sales and marketing capabilities successfully, either on our own or in collaboration with third parties, we will not be successful in commercializing ~~inebilizumab or any of~~ our other product candidates that receive marketing approval or any such commercialization may experience delays or limitations. If we are not successful in commercializing ~~inebilizumab~~Uplizna® or any of our other product candidates, either on our own or through collaborations with one or more third parties, our business, results of operations, financial condition and prospects will be materially adversely affected.

Product liability lawsuits against us could cause us to incur substantial liabilities and to limit commercialization of any products that we may develop.

We face an inherent risk of product liability exposure related to the evaluation of our product candidates in human clinical trials and will face an even greater risk ifwith wethe ~~commercially~~commercialization ~~sell~~of ~~any products that we may develop~~Uplizna®. If we cannot successfully defend ourselves against claims that our product candidates or products caused injuries, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

•

decreased demand for any product candidates or products that we may develop;

•

injury to our reputation and significant negative media attention;

•

withdrawal of clinical trial participants;

•

significant costs to defend the related litigation;

•

substantial monetary awards to trial participants or patients;

•

regulatory investigations, product recalls or withdrawals, or labeling, marketing or promotional restrictions;

•

loss of revenue;

•

reduced resources of our management to pursue our business strategy; and

•

the inability to successfully commercialize any products that we may develop.

Our current product liability insurance coverage may not be adequate to cover all liabilities that we may incur. We may need to increase our insurance coverage as we expand our clinical trials orand ifhave increased our insurance coverage as we commence commercialization of ~~our product candidates~~Uplizna®. Insurance coverage is increasingly expensive. Our insurance policies also have various exclusions and deductibles, and we may be subject to a product liability claim for which we have no coverage. We may not be able to maintain insurance coverage at a reasonable cost or in an amount adequate to satisfy any liability that may arise.

The sizes of the patient populations suffering from some of the diseases we are targeting are small and based on estimates that may not be accurate.

Our projections of both the number of people who have some of the diseases we are targeting, as well as the subset of people with these diseases who have the potential to benefit from treatment with ~~inebilizumab~~Uplizna® and any ~~other~~of our future product candidates, are estimates. These estimates have been derived from a variety of sources, including scientific literature, surveys of clinics, physician interviews, patient foundations and market research, and may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of these diseases. The number of patients may turn out to be lower than expected. Additionally, the potentially addressable patient population for ~~inebilizumab~~Uplizna® and any ~~other~~of our future product candidates may be limited or may not be amenable to treatment with ~~inebilizumab~~Uplizna® and any ~~other~~of our products, if and when approved. Even if we obtain significant market share for ~~inebilizumab~~Uplizna® and any ~~other~~of our products (if and when they are approved), small potential target populations for certain indications means we may never achieve profitability without obtaining market approval for additional indications.

Risks Related to Our Intellectual Property

If we are unable to obtain and maintain intellectual property protection for our technology and products, or if the scope of the intellectual property protection obtained is not sufficiently broad, our competitors could ~~commercialize technology and products similar or identical to ours, and our ability to successfully commercialize our technology and products may be impaired.~~

commercialize technology and products similar or identical to ours, and our ability to successfully commercialize our technology and products may be impaired.

Our success depends in large part on our ability to obtain and maintain patents in the United States and other countries that adequately protect our proprietary technology and products. We seek to protect our proprietary position by filing patent applications in the United States and in foreign countries that cover our novel technologies and product candidates. Our patent portfolio currently includes both patents and patent applications, most of which were acquired from MedImmune.

The patent prosecution process is expensive and time-consuming. We may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. We may choose not to seek patent protection for certain innovations and may choose not to pursue patent protection in certain jurisdictions. Under the laws of certain jurisdictions, patents or other intellectual property rights may be unavailable or limited in scope. It is also possible that we will fail to identify patentable aspects of our research and development before it is too late to obtain patent protection.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and has in recent years been the subject of much litigation. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, we cannot know with certainty whether we were the first to make the inventions claimed in our owned or licensed patents or pending patent applications, or that we were the first to file for patent protection of such inventions. As a result, the issuance, scope, validity, enforceability, term and commercial value of our patent rights are highly uncertain. Our pending and future patent applications may not result in patents being issued which protect our technology or products, in whole or in part, or which effectively prevent others from commercializing competitive technologies and products. For example, to date, none of our U.S. patent applications directed to VIB7734 have issued as patents. Changes in either the patent laws or interpretation of the patent laws in the United States and other countries may diminish the value of our patents or narrow the scope of our patent protection.

or interpretation of the patent laws in the United States and other countries may diminish the value of our patents or narrow the scope of our patent protection.

Recent patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents. On September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law. The Leahy-Smith Act includes a number of significant changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted and may also affect patent litigation. The U.S. Patent and Trademark Office, or U.S. PTO, recently developed new regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, and in particular, the first-to-file provisions, became effective on March 16, 2013. The Leahy-Smith Act also created certain new administrative adversarial proceedings, discussed below. It is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business and financial condition.

The U.S. Supreme Court has issued opinions in patent cases in the last few years that many consider may weaken patent protection in the United States, either by narrowing the scope of patent protection available in certain circumstances, holding that certain kinds of innovations are not patentable or generally otherwise making it easier to invalidate patents in court. Additionally, there have been recent proposals for additional changes to the patent laws of the United States and other countries that, if adopted, could impact our ability to obtain patent protection for our proprietary technology or our ability to enforce our proprietary technology. Depending on future actions by the U.S. Congress, the U.S. courts, the U.S. PTO and the relevant law-making bodies in other countries, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future.

Even if our patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors from competing with us or otherwise provide us with any competitive advantage. Our competitors may be able to circumvent our owned or licensed patents by developing similar or alternative technologies or products in a non-infringing manner.

The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our owned and licensed patents may be challenged in the courts or patent offices in the United States and in other countries. Such challenges may result in loss of exclusivity or freedom to operate or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our technology and products. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

such candidates might expire before or shortly after such candidates are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

During patent prosecution in the United States and in most foreign countries, a third party can submit prior art or arguments to the reviewing patent office to attempt to prevent the issuance of a competitor’s patent. For example, our pending patent applications may be subject to a third-party preissuance submission of prior art to the U.S. PTO or an Observation in Europe. Such submission may convince the receiving patent office not to issue the patent. In addition, if the breadth or strength of protection provided by our patents and patent applications is reduced by such third party submission, it could affect the value of our resulting patent or dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates.

The risks described here pertaining to our patents and other intellectual property rights also apply to any intellectual property rights that we may license in the future, and any failure to obtain, maintain and enforce these rights could have a material adverse effect on our business. In some cases we may not have control over the prosecution, maintenance or enforcement of the patents that we license, and our licensors may fail to take the steps that we believe are necessary or desirable in order to obtain, maintain and enforce the licensed patents. In addition, even where we now have the right to control patent prosecution of patents and patent applications we have licensed from third parties or the patents and patent applications we acquired from others, we may still be adversely affected or prejudiced by actions or inactions of our licensors or the previous owners of such patents or patent applications. Any inability on our part to protect adequately our intellectual property may have a material adverse effect on our business, operating results and financial position.

Some intellectual property has been discovered through government -funded programs and thus may be subject to federal regulations such as “march-in” rights, certain reporting requirements and a preference for U.S.-based companies. Compliance with such regulations may limit our exclusive rights, and limit our ability to contract with non-U.S. manufacturers.

companies. Compliance with such regulations may limit our exclusive rights, and limit our ability to contract with non-U.S. manufacturers.

Some of our intellectual property rights, specifically, intellectual property rights related to inebilizumab that are in-licensed from Duke University, were generated through the use of U.S. government funding and are therefore subject to certain federal regulations. As a result, the U.S. government may have certain rights to intellectual property embodied in certain of our current or future product candidates pursuant to the Bayh-Dole Act of 1980, or the Bayh-Dole Act. These U.S. government rights in certain inventions developed under a government-funded program include a non-exclusive, non-transferable, irrevocable worldwide license to use inventions for any governmental purpose. In addition, the U.S. government has the right, under certain limited circumstances, to require us to grant exclusive, partially exclusive, or non-exclusive licenses to any of these inventions to a third party if it determines that: (i) adequate steps have not been taken to commercialize the invention; (ii) government action is necessary to meet public health or safety needs; or (iii) government action is necessary to meet requirements for public use under federal regulations (also referred to as “march-in rights”). To our knowledge, however, the U.S. government has, to date, not exercised any march-in rights on any patented technology that was generated using U.S. government funds. The U.S. government also has the right to take title to these inventions if we or the applicable grantee fail to disclose the invention to the government and fail to file an application to register the intellectual property within specified time limits. Intellectual property generated under a government funded program is also subject to certain reporting requirements, compliance with which may require us to expend substantial resources. In addition, the U.S. government requires that any products embodying the subject invention or produced through the use of the subject invention be manufactured substantially in the United States. The manufacturing preference requirement can be waived if the owner of the intellectual property can show that reasonable but unsuccessful efforts have been made to grant licenses on similar terms to potential licensees that would be likely to manufacture substantially in the United States or that under the circumstances domestic manufacture is not commercially feasible. This preference for U.S. manufacturers may limit our ability to contract with non-U.S. product manufacturers for products covered by such intellectual property. To the extent any of our current or future intellectual property is generated through the use of U.S. government funding, the provisions of the Bayh-Dole Act may similarly apply.

We may become involved in administrative adversarial proceedings in the U.S. PTO or in the patent offices of foreign countries brought by a third party to attempt to cancel or invalidate our patent rights, which could be expensive, time consuming and cause a loss of patent rights.

The Leahy-Smith Act created new and additional procedures to challenge issued patents in the U.S. PTO, including post-grant review, derivation proceedings and inter partes review proceedings, which some third parties have been using to invalidate selected or all claims of issued patents of competitors. For a patent with a priority date of March 16, 2013 or later, a petition for post-grant review can be filed by a third party in a nine month window from issuance of the patent. A petition for inter partes review can be filed immediately following the issuance of a patent (or at any time thereafter) ~~if the patent was filed prior to March 16, 2013~~. A petition for inter partes review can be filed after the nine month period for filing a post-grant review petition has expired for a patent with a priority date of March 16, 2013 or later. Post-grant review proceedings can be brought on any ground of challenge, whereas inter partes review proceedings can only be brought to raise a challenge based on published prior art. These administrative adversarial actions at the U.S. PTO review patent claims without the presumption of validity afforded to U.S. patents in lawsuits in U.S. federal courts, use a lower burden of proof than used by U.S. federal courts. Moreover, any third party can request an inter partes review or post-grant review and does not have to satisfy the traditional requirements for standing to challenge the validity of an issued U.S. patent. Because of these differences between U.S. administrative and judicial adversarial patent proceedings, it is generally considered easier for a competitor or third party to have one or more U.S. patent claims cancelled in a patent office post-grant review or inter partes review proceeding than invalidated in a litigation in a U.S. federal court. If any of our patents are challenged by a third party in such a U.S. patent office proceeding, there is no guarantee that we will be successful in defending the patent, which would result in a loss of the challenged patent right to us.

If any of our patents are challenged by a third party in such a U.S. patent office proceeding, there is no guarantee that we will be successful in defending the patent, which would result in a loss of the challenged patent right to us.

Opposition or invalidation procedures are also available in most foreign countries. Many foreign authorities, such as the authorities at the European Patent Office, have only post-grant opposition proceedings, however, certain countries, such as India, have both pre-grant and post-grant opposition proceedings. If any of our patents are challenged in a foreign opposition or invalidation proceeding, we could face significant costs to defend our patents, and we may not be successful. Uncertainties resulting from the initiation, continuation or loss of such proceedings could have a material adverse effect on our ability to compete in the market place. Further, in many foreign jurisdictions, the losing party must pay the attorneys’ fees of the winning party, which can be substantial.

We may have to file one or more lawsuits in court to prevent a third party from selling a product or using a product in a manner that infringes our patent, which could be expensive, time consuming and unsuccessful, and ultimately result in the loss of our proprietary market.

Because competition in our industry is intense, competitors may infringe or otherwise violate our issued patents, patents of our licensors or other intellectual property. To counter infringement or unauthorized use, we may be required to file infringement lawsuits, which can be expensive and time consuming. Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their patents. In addition, in a patent infringement proceeding, a court may decide that a patent of ours is invalid or unenforceable, in whole or in part, construe the patent’s claims narrowly or refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation proceeding could put one or more of our patents at risk of being invalidated or interpreted narrowly. We may also elect to enter into license agreements in order to settle patent infringement claims or to resolve disputes prior to litigation, and any such license agreements may require us to pay royalties and other fees that could be significant. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure.

A number of pharmaceutical companies have been the subject of intense review by the U.S. Federal Trade Commission or a corresponding agency in another country based on how they have conducted or settled drug patent litigation, and certain reviews have led to an allegation of an anti-trust violation, sometimes resulting in a fine or loss of rights. We cannot be sure that we would not also be subject to such a review or that the result of the review would be favorable to us, which could result in a fine or penalty.

The U.S. Federal Trade Commission, or FTC, and various private plaintiff class actions have brought a number of lawsuits in federal court in recent years to challenge Hatch Waxman Abbreviated New Drug Application, or ANDA, litigation settlements between innovator companies and generic companies as anti-competitive violations of the Sherman Act. The FTC has successfully argued that if an innovator firm, as part of a patent litigation settlement with a generic company, agrees to provide anything of value to a generic firm to not launch or to delay launch of an authorized generic during the 180-day period granted to the first generic company to challenge an Orange Book listed patent covering an innovator drug, or negotiates a delay to a generic company’s entry, the FTC may consider it an unlawful “reverse payment” ” that violates the antitrust laws. In 2013, the U.S. Supreme Court, inheld ~~a five-to-three decision~~ in FTC v. Actavis, Inc. ~~held~~ that ~~whether a “~~reverse payment” settlement involving the exchange of consideration for a delay in entry is subject to an anticompetitive analysis depends on five considerations: (a) the potential for genuine adverse effects on competition; (b) the justification of payment; (c) the patentee’s ability to bring about anticompetitive harm; (d) whether the size of the payment is a workable surrogate for the patent’s weakness; and (e) that antitrust liability for large unjustified payments does not prevent litigating parties from settling their lawsuits, for example, by allowing the generic to enter the market before the patent expires without the patentee’s paying the generic. Furthermore, whether a reverse payment is justified depends upon its size, its scale in relation to the patentee’s anticipated future litigation costs, its independence from other services for which it might represent payment, as was the case in Actavis, and the lack of any other convincing justification. The Court held that reverse payment settlements can potentially violate antitrust laws and are subject to the standard antitrust rule-of-reason analysis~~, with the burden of proving that an agreement is unlawful on the FTC and leaving to lower courts the structuring of such rule of reason analysis~~. InLower ~~the wake of that decision, lower~~ courts continue to adjudicate government enforcement and private actions challenging “reverse payments” as violations of the antitrust laws. If we are faced with product patent litigation challenging the validity of any patents we own, including Hatch Waxman litigation with a generic company, any settlement of that litigation could later be challenged by the FTC or private plaintiffs as unlawful, and we could face a significant expense or penalty.

We may become party to, or threatened with, future adversarial proceedings or litigation regarding intellectual property rights covering our products and technology, including interference or derivation proceedings before the U.S. PTO. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future. We may, in the future, receive letters or other threats or claims from third parties inviting us to take licenses under, or alleging that we infringe, their patents. We cannot be certain that we have identified all pending or issued patents of potential relevance to our product candidates or technologies. We may fail to identify relevant patent rights, or incorrectly conclude that an issued patent is invalid or not infringed by our activities. If any third-party patents were asserted against us, even if we believe such claims are without merit, there is no assurance that a court would find in our favor on questions of infringement, validity, enforceability or priority. A court of competent jurisdiction could hold that the asserted third party patents are valid, enforceable and infringed, which could materially and adversely affect our ability to commercialize our products. We may choose to or, if we are found to infringe a third party’s intellectual property rights, we could be required to obtain a license from such third party to continue developing and marketing our products and technology. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. We could be forced, including by court order, to cease commercializing the infringing technology or product. In addition, we could be found liable for monetary damages, including treble damages and

However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. We could be forced, including by court order, to cease commercializing the infringing technology or product. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees if we are found to have willfully infringed a patent. A finding of infringement could prevent us from commercializing our product candidates or force us to cease some of our business operations, which could materially harm our business. Claims that we have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business.

Even if we are successful in defending against intellectual property claims, litigation or other legal proceedings relating to such claims may cause us to incur significant expenses, and could distract our technical and management personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our ordinary shares. Such litigation or proceedings could substantially increase our operating losses and reduce our resources available for development activities. We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their substantially greater financial resources. Uncertainties resulting from the initiation and continuation of litigation or other intellectual property related proceedings could have a material adverse effect on our ability to compete in the marketplace.

The patent protection and patent prosecution for some of our product candidates is dependent on third parties.

While we normally seek and gain the right to fully prosecute the patents relating to our product candidates, there may be times when patents relating to our product candidates are controlled by our licensors. This is the case with current patents and patent applications licensed from MedImmune related to VIB4920, and those licensed from Duke University related to inebilizumab. If we, or any of our future licensing partners fail to appropriately file, prosecute and maintain patent protection for patents covering any of our product candidates, our ability to develop and commercialize those product candidates may be adversely affected and we may not be able to prevent competitors from making, using, and selling competing products. In addition, even where we now have the right to control patent prosecution of patents and patent applications we have licensed from third parties, we may still be adversely affected or prejudiced by actions or inactions of our licensors.

We are a party to a number of intellectual property license agreements that are important to our business and expect to enter into additional license agreements in the future. Our existing license agreements impose, and we expect that future license agreements will impose, various diligence, milestone payment, royalty and other obligations on us. If we fail to comply with our obligations under these agreements, or we are subject to a bankruptcy, we may be required to make certain payments to the licensor, we may lose the exclusivity of our license, or the licensor may have the right to terminate the license, in which event we would not be able to develop or market products covered by the license. This includes (i) our licenses with Duke University and Dana-Farber Cancer Institute related to inebilizumab, (ii) our license with SBI Biotech related to VIB7734, (iii) our license with MedImmune related to VIB4920, (iv) our sublicense with MedImmune for its license with Lonza related to inebilizumab and VIB7734, (v) our sublicense with MedImmune for its license with BioWa related to inebilizumab, and (vi) our sublicense with MedImmune for its license with BioWa and Lonza related to VIB7734. Additionally, the milestone and other payments associated with these licenses and other agreements will make it less profitable for us to develop our drug candidates.

In some cases, patent prosecution of our licensed technology is controlled solely by the licensor. If our licensors fail to obtain and maintain patent or other protection for the proprietary intellectual property we license from them, we could lose our rights to the intellectual property or our exclusivity with respect to those rights, and our competitors could market competing products using the intellectual property. In certain cases, we control the prosecution of patents resulting from licensed technology. In the event we breach any of our obligations related to such prosecution, we may incur significant liability to our licensing partners. Licensing of intellectual property is of critical importance to our business and involves complex legal, business, and scientific issues. Disputes may arise regarding intellectual property subject to a licensing agreement, including but not limited to:

•

the scope of rights granted under the license agreement and other interpretation-related issues;

•

the extent to which our technology and processes infringe intellectual property of the licensor that is not subject to the licensing agreement;

•

the sublicensing of patent and other rights;

•

our diligence obligations under the license agreement and what activities satisfy those diligence obligations;

•

the ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors, our collaborators and us;

•

the priority of invention of patented technology; and

•

the fulfilment of our obligations under the license.

If disputes over intellectual property and other rights that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates.

The agreements under which we currently in-license intellectual property from third parties are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could harm our business, financial condition, results of operations and prospects. If any of our current or future licenses or material relationships or any in-licenses upon which our current or future licenses are based are terminated or breached, we may:

•

lose our rights to develop and market our current product candidates or any future product candidates;

•

lose patent protection for our current product candidates or any future product candidates;

•

experience significant delays in the development or commercialization of our current product candidates or any future product candidates;

•

not be able to obtain any other licenses on acceptable terms, if at all; or

•

incur liability for damages.

If we experience any of the foregoing, it could harm our business, financial condition and results of operations.

We may not be able to effectively enforce our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on our product candidates in all countries throughout the world would be prohibitively expensive, and therefore we only file for patent protection in selected countries. The requirements for patentability may differ in certain countries, particularly in developing countries. Moreover, our ability to protect and enforce our intellectual property rights may be adversely affected by unforeseen changes in foreign intellectual property laws.

The laws of foreign countries may not protect our rights to the same extent as the laws of the United States. For example, Europe, India, China and certain other countries do not allow patents for methods of treating the human body. Many companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions that do not favor patent protection on drugs. This could make it difficult for us to stop the infringement of our patents or the misappropriation of our other intellectual property rights. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own drugs and, further, may export otherwise infringing drugs to territories where we have patent protection, if our ability to enforce our patents to stop infringing activities is inadequate. These drugs may compete with our product candidates, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

These drugs may compete with our product candidates, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Proceedings to enforce our patent rights in foreign jurisdictions, whether or not successful, could result in substantial costs and divert our efforts and resources from other aspects of our business. Furthermore, while we intend to protect our intellectual property rights in the major markets for our product candidates, we cannot ensure that we will be able to initiate or maintain similar efforts in all jurisdictions in which we may wish to market our product candidates. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate.

A number of foreign countries have stated that they are willing to issue compulsory licenses to patents held by innovator companies on approved drugs to allow the government or one or more third party companies to sell the approved drug without the permission of the innovator patentee where the foreign government concludes it is in the public interest. India, for example, has used such a procedure to allow domestic companies to make and sell patented drugs without innovator approval. There is no guarantee that patents covering any of our products will not be subject to a compulsory license in a foreign country, or that we will have any influence over if or how such a compulsory license is granted. Further, Brazil allows its regulatory agency ANVISA to participate in deciding whether to grant a drug patent in Brazil, and patent grant decisions are made based on several factors, including whether the patent meets the requirements for a patent and whether such a patent is deemed in the country’s interest. In addition, several other countries have created laws that make it more difficult to enforce drug patents than patents on other kinds of technologies. Further, under the treaty on the Trade-Related Aspects of Intellectual Property, or TRIPS, as interpreted by the Doha Declaration, countries in which drugs are manufactured are required to allow exportation of the drug to a developing country that lacks adequate manufacturing capability. Therefore, our product markets in the United States or foreign countries may be affected by the influence of current public policy on patent issuance, enforcement or involuntary licensing in the healthcare area.

Therefore, our product markets in the United States or foreign countries may be affected by the influence of current public policy on patent issuance, enforcement or involuntary licensing in the healthcare area.

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due to be paid to the U.S. PTO and various governmental patent agencies outside of the United States in several stages over the lifetime of the patents and/or applications. We have systems in place to remind us to pay these fees, and we employ an outside firm and rely on our outside counsel to pay these fees due to non-U.S. patent agencies. We employ reputable law firms and other professionals to help us comply, and in many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules. However, there are situations in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, our competitors might be able to enter the market and this circumstance would have a material adverse effect on our business.

Intellectual property litigation could cause us to spend substantial resources and distract our personnel from their normal responsibilities.

Litigation or other legal proceedings relating to intellectual property claims, with or without merit, is unpredictable and generally expensive and time consuming and is likely to divert significant resources from our core business, including distracting our technical and management personnel from their normal responsibilities. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities.

We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources and more mature and developed intellectual property portfolios. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or misappropriating or from successfully challenging our intellectual property rights. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace.

We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property, or claiming ownership of what we regard as our own intellectual property.

Although we try to ensure that our employees do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that these employees or we have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such employee’s former employer. Litigation may be necessary to defend against these claims.

In addition, while it is our policy to require our employees and contractors who may be involved in the development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact develops intellectual property that we regard as our own. Our and their assignment agreements may not be self-executing or may be breached, and we may be forced to bring claims against third parties, or defend claims they may bring against us, to determine the ownership of what we regard as our intellectual property.

If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to management.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to seeking patents for some of our technology and product candidates, we also rely on trade secrets, including unpatented know-how, technology and other proprietary information, to maintain our competitive position. We seek to protect these trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our employees, corporate collaborators, outside scientific collaborators, contract manufacturers, consultants, advisors and other third parties. We seek to protect our confidential proprietary information, in part, by entering into confidentiality and invention or patent assignment agreements with our employees and consultants, however, we cannot be certain that such agreements have been entered into with all relevant parties. Moreover, to the extent we enter into such agreements, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would be harmed.

Risks Related to Employee Matters, Managing Growth and Other Risks Related to Our Business

We currently have a limited number of employees, and our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel.*

We are a ~~clinical-stage~~biotechnology company, and, as of December 31, ~~2019~~2020, had ~~139~~170 employees. We are highly dependent on the research and development, clinical and business development expertise of Zhengbin (Bing) Yao, Ph.D., our President and Chief Executive Officer, and Jörn Drappa, M.D., Ph.D., our Chief Medical Officer, as well as the other principal members of our management, scientific and clinical team. Although we have entered into employment agreements with some of our executive officers, each of them may terminate his or her employment with us at any time. We do not maintain “key person” insurance for any of our executives or other employees. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors may have commitments under consulting or advisory contracts with other entities that may limit their availability to us. If we are unable to continue to attract and retain high quality personnel, our ability to pursue our growth strategy will be limited.

Recruiting and retaining qualified scientific, clinical, manufacturing, sales and marketing personnel will also be critical to our success. The loss of the services of our executive officers or other key employees could impede the achievement of our research, development and commercialization objectives and seriously harm our ability to successfully implement our business strategy. Furthermore, replacing executive officers and key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, obtain marketing approval of and commercialize products. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also face competition for the hiring of scientific and clinical personnel from universities and research institutions. Failure to succeed in clinical trials may make it more challenging to recruit and retain qualified scientific ~~personnel. If we are unable to continue to attract and retain high quality personnel, our ability to pursue our growth strategy will be limited.~~

personnel. If we are unable to continue to attract and retain high quality personnel, our ability to pursue our growth strategy will be limited.

To manage our anticipated development and expansion, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. Also, our management may need to divert a disproportionate amount of its attention away from its day-to-day activities and devote a substantial amount of time to managing these development activities. Due to our ~~limited~~focused resources, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. This may result in weaknesses in our infrastructure, give rise to operational mistakes, loss of business opportunities, loss of employees and reduced productivity among remaining employees. The physical expansion of our operations may lead to significant costs and may divert financial resources from other projects, such as the development of our product candidates. If our management is unable to effectively manage our expected development and expansion, our expenses may increase more than expected, our ability to generate or increase our revenue could be reduced and we may not be able to implement our business strategy. Our future financial performance and our ability to commercialize our product candidates, if approved, and compete effectively will depend, in part, on our ability to effectively manage the future development and expansion of our company.

of our product candidates. If our management is unable to effectively manage our expected development and expansion, our expenses may increase more than expected, our ability to generate or increase our revenue could be reduced and we may not be able to implement our business strategy. Our future financial performance and our ability to commercialize our product candidates, if approved, and compete effectively will depend, in part, on our ability to effectively manage the future development and expansion of our company.

Unfavorable global economic conditions could adversely affect our business, financial condition or results of operations.

Our results of operations could be adversely affected by general conditions in the global economy and in the global financial markets. The last global financial crisis caused extreme volatility and disruptions in the capital and credit markets. A severe or prolonged economic downturn, such as the last global financial crisis, could result in a variety of risks to our business, including our ability to raise additional capital when needed on acceptable terms, if at all. A weak or declining economy could also strain our suppliers, possibly resulting in supply disruptions. Any of the foregoing could harm our business, and we cannot anticipate all of the ways in which the current economic climate and financial market conditions could adversely impact our business.

Our employees, principal investigators, CROs and consultants may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements and insider trading.*

We are exposed to the risk that our employees, principal investigators, CROs and consultants may engage in fraudulent conduct or other illegal activity. Misconduct by these parties could include intentional, reckless and/or negligent conduct or other unauthorized activities to us that violate the regulations of the FDA and other regulatory authorities, including those laws requiring the reporting of true, complete and accurate information to such authorities; healthcare fraud and abuse laws and regulations in the United States and abroad; or laws that require the reporting of financial information or data accurately. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. These laws also involve the improper use of information obtained in the course of clinical trials or creating fraudulent data in our nonclinical studies or clinical trials, which could result in regulatory sanctions and cause serious harm to our reputation. We have adopted a code of conduct applicable to all of our employees, but it is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. Additionally, we are subject to the risk that a person could allege such fraud or other misconduct, even if none occurred. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

We may expend our limited resources to pursue a particular product candidate and fail to capitalize on product candidates that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we focus on specific product candidates. As a result, we may forgo or delay pursuit of opportunities with other product candidates that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs and product candidates for specific indications may not yield any commercially viable product candidates. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate.

We may acquire businesses or products, or form strategic alliances, in the future, and we may not realize the benefits of such acquisitions or alliances.

We may acquire additional businesses or products, form strategic alliances or create joint ventures with third parties that we believe will complement or augment our existing business. If we acquire businesses with promising markets or technologies, we may not be able to realize the benefit of acquiring such businesses if we are unable to successfully integrate them with our existing operations and company culture. We may encounter numerous difficulties in developing, manufacturing and marketing any new products resulting from a strategic alliance or acquisition that delay or prevent us from realizing their expected benefits or enhancing our business. We cannot assure you that, following any such acquisition, we will achieve the expected synergies to justify the transaction.

prevent us from realizing their expected benefits or enhancing our business. We cannot assure you that, following any such acquisition, we will achieve the expected synergies to justify the transaction.

We rely significantly on information technology and any failure, inadequacy, interruption or security lapse of that technology, including any cyber security incidents, could harm our ability to operate our business effectively.

Despite the implementation of security measures, our internal computer systems and those of third parties with which we contract are vulnerable to damage from cyber-attacks, computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. System failures, accidents or security breaches could cause interruptions in our operations, and could result in a material disruption of our clinical activities and business operations, in addition to possibly requiring substantial expenditures of resources to remedy. The loss of clinical trial data could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur a liability and our research and development programs and the development of our product candidates could be delayed.

We or the third parties upon which we depend may be adversely affected by earthquakes or other natural disasters and/or health epidemics and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Earthquakes or other natural disasters could severely disrupt our operations and have a material adverse effect on our business, results of operations, financial condition and prospects. If a natural disaster, health epidemic, power outage or other event occurred that prevented us from using all or a significant portion of our headquarters and/or lab space, that damaged critical infrastructure, such as the manufacturing facilities of our third-party contract manufacturers, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time. The disaster recovery and business continuity plans we have in place may prove inadequate in the event of a serious disaster or similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which could have a material adverse effect on our business.

A pandemic, epidemic, or outbreak of an infectious disease, such as COVID-19 may materially and adversely affect our business and our financial results.*

The novel coronavirus outbreak has affected segments of the global economy and may materially affect our operations, including potentially significant interruption of our clinical trial activities and pre-commercial launch activities. COVID-19 originated in Wuhan, China, in December 2019 the virus has since spread to multiple countries, including the United States, where we are currently conducting our clinical trials. The continued spread of the coronavirus may result in a period of business disruption, including material delays in our clinical trials or material delays or disruptions in our ~~pre-commercial~~commercialization ~~launch activities~~efforts. In addition, there could be a potential effect of COVID-19 to the business at FDA or other health authorities, which could result in delays of reviews and approvals, including with respect to our product candidates.

The continued spread globally could also have a material adverse effect our clinical trial operations in the United States and elsewhere, including our ability to recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19 if an outbreak occurs in their geography.

We are closely monitoring the potential impact of the coronavirus outbreak, and the associated restrictions on travel and work that have been implemented, on our business and clinical trials. The extent to which the coronavirus impacts us will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the coronavirus and the actions to contain the coronavirus or treat its impact, among others. At present, we are not experiencing significant impact or delays from COVID-19 on our business, operations ~~and, if approved, commercialization plans~~. However, in order to prioritize patient health and that of the investigators at clinical trial sites, we ~~have~~had paused enrollment of new patients ~~for four weeks~~ in certain of our clinical trials, including our Phase 2b trial of VIB4920 in ~~Sjogren~~Sjögren’s syndrome, our Phase 2 trial of VIB4920 in rheumatoid arthritis and our Phase 2 trial of inebilizumab in kidney transplant ~~rejection,~~desensitization. ~~and~~We recently resumed all our clinical trials except the Phase 2 trial of inebilizumab in kidney transplant desensitization. The coronavirus outbreak may further delay enrollment in our planned or ongoing clinical trials due to prioritization of hospital resources toward the outbreak, the protection of the health of patients and investigators at the clinical trial sites, and restrictions on work and travel. In addition, some patients may be unwilling to enroll in our trials or be unable to comply with clinical trial protocols if quarantines or travel restrictions impede patient movement or interrupt healthcare services. These and other factors could significantly delay our ability to conduct clinical trials or release clinical trial results. Our ability to re-open enrollment in the paused clinical trials will be dependent on many factors, including the progression of the pandemic and its impact on patients and the investigators at our clinical trial sites. Furthermore, our ability to re-open enrollment in the paused clinical trial will require collaboration with, and permission from, each of the clinical trial sites. Over the coming weeks and months, we will continue to monitor carefully the situation with respect to each of our clinical trials and follow guidance from local and federal health authorities. Additionally, we believe that the pandemic has impacted the frequency of patient visits to physicians and has impacted physician office operations. These changes may impact prescribing rates of Uplizna® or other products, if approved.

COVID-19 may also affect employees of third-party contract research organizations located in affected geographies that we rely upon to carry out our clinical trials. The spread of COVID-19, or another infectious disease, could also negatively affect the operations at our third-party manufacturers, which could result in delays or disruptions in the supply of our product candidates. In addition, we have taken precautionary measures, and may take additional measures, intended to help minimize the risk of the virus to our employees, including temporarily requiring all employees to work remotely, suspending all non-essential travel worldwide for our employees, and discouraging employee attendance at industry events and in-person work-related meetings, which could negatively affect our business.

supply of our product candidates. In addition, we have taken precautionary measures, and may take additional measures, intended to help minimize the risk of the virus to our employees, including temporarily requiring all employees to work remotely, suspending all non-essential travel worldwide for our employees, and discouraging employee attendance at industry events and in-person work-related meetings, which could negatively affect our business.

We cannot presently predict the extent to which current or future business shutdowns and disruptions may impact or limit our ability or the ability of any of the third parties with which we engage to conduct business in the manner and on the timelines presently planned. Any such impacts or limitations could have a material adverse impact on our business and our results of operation and financial condition. While the potential economic impact brought by and the duration of the coronavirus outbreak may be difficult to assess or predict, a widespread pandemic could result in significant disruption of global financial markets, reducing our ability to access capital, which could in the future negatively affect our liquidity. In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect our business and the value of our common stock

We or third parties upon whom we depend may be adversely affected by natural disasters and/or health epidemics, and our business, financial condition and results of operations could be adversely affected.

Natural disasters could severely disrupt our operations and have a material adverse effect on our business operations. If a natural disaster, health epidemic, or other event beyond our control occurred that prevented us from using all or a significant portion of our office and/or lab spaces, that damaged critical infrastructure, such as the manufacturing facilities of our third-party contract manufacturers or our collaborators, or that otherwise disrupted operations, it may be difficult for us to continue our business for a substantial period of time.

Risks Related to Our Common Stock

The price of our common stock may be volatile and fluctuate substantially, which could result in substantial losses to stockholders.*

The market price of shares of our common stock could be subject to wide fluctuations in response to many risk factors listed in this section and many others beyond our control, including:

•

results of nonclinical and clinical trials of our product candidates, including inebilizumab, VIB4920 and VIB7734;

•

results of clinical trials of our competitors’ products;

• regulatory actions with respect to our products or our competitors’ products~~, including the approval by the FDA of our BLA for inebilizumab in patients with NMOSD~~;

•

actual or anticipated fluctuations in our financial condition and operating results;

•

publication of research reports by securities analysts about us or our competitors or our industry;

•

our failure or the failure of our competitors to meet analysts’ projections or guidance that we or our competitors may give to the market;

•

developments or disputes concerning patent applications, issued patents or other proprietary rights;

•

additions and departures of key personnel;

•

strategic decisions by us or our competitors, such as acquisitions, collaborations, divestitures, spin-offs, joint ventures, strategic investments or changes in business strategy;

•

the passage of legislation or other regulatory developments in the United States and other countries affecting us or our industry;

•

fluctuations in the valuation of companies perceived by investors to be comparable to us;

•

sales of our common stock by us, our insiders or our other stockholders;

•

speculation in the press or investment community;

•

announcement or expectation of additional financing efforts;

•

changes in accounting principles;

•

changes in the structure of healthcare payment systems;

•

terrorist acts, acts of war or periods of widespread civil unrest;

•

natural disasters and other calamities;

•

overall performance of the equity markets;

•

changes in market conditions for pharmaceutical and biopharmaceutical stocks;

•

changes in general market, industry and economic conditions; and

•

the other factors described in this “Risk Factors” section.

In addition, the stock market has experienced significant volatility, particularly with respect to pharmaceutical, biotechnology and other life sciences company stocks. The volatility of pharmaceutical, biotechnology and other life sciences company stocks often does not relate to the operating performance of the companies represented by the stock. In the past, securities class action litigation has often been initiated against companies following periods of volatility in their stock price. This type of litigation could result in substantial costs and divert our management’s attention and resources, and could also require us to make substantial payments to satisfy judgments or to settle litigation.

Our executive officers and directors, combined with our stockholders who own more than 5% of our outstanding common stock, in the aggregate, beneficially own shares representing a majority of our outstanding capital stock. As a result, if these stockholders were to choose to act together, they would be able to influence our management and affairs and the outcome of matters submitted to our stockholders for approval, including the election of directors and any sale, merger, consolidation, or sale of all or substantially all of our assets. This concentration of ownership control may adversely affect the market price of our common stock by:

•

delaying, deferring or preventing a change in control;

•

entrenching our management and the board of directors;

•

impeding a merger, consolidation, takeover or other business combination involving us that other stockholders may desire; and/or

•

discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of us.

Provisions in our corporate charter documents and under Delaware law could make an acquisition of our company, which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.*90

Provisions in our ~~third~~corporate ~~amended~~charter ~~and~~documents ~~restated certificate of incorporation~~ and ~~our~~under ~~amended~~Delaware ~~and~~law ~~restated~~could ~~bylaws may~~ discourage, ~~delay~~takeover orattempts ~~prevent~~and amake ~~merger,~~more ~~acquisition~~difficult orand ~~other change in control of our company that stockholders~~ may consider favorable, including transactions in which you might otherwise receive a premium for your shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock. In addition, because our board of directors is responsible for appointing the members of our management team, these provisions may frustrate or prevent ~~any~~ attempts by our stockholders to replace or remove our current management ~~by making it more difficult for stockholders to replace members of our board of directors~~. Although we believe these provisions collectively provide for an opportunity to obtain greater value for stockholders by requiring potential acquirers to negotiate with our board of directors, they would apply even if an offer rejected by our board of directors were considered beneficial by some stockholders. Among other things, these provisions:

Provisions in our third amended and restated certificate of incorporation and our amended and restated bylaws may discourage, delay or prevent a change in control of our company. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock. In addition, because our board of directors is responsible for appointing the members of our management team, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors. Although we believe these provisions collectively provide for an opportunity to obtain greater value for stockholders by requiring potential acquirers to negotiate with our board of directors, they would apply even if an offer rejected by our board of directors were considered beneficial by some stockholders. Among other things, these provisions:

•

establish a classified board of directors such that only one of three classes of directors is elected each year;

•

allow the authorized number of our directors to be changed only by resolution of our board of directors;

•

limit the manner in which stockholders can remove directors from our board of directors;

•

establish advance notice requirements for stockholder proposals that can be acted on at stockholder meetings and nominations to our board of directors;

•

require that stockholder actions must be effected at a duly called stockholder meeting and prohibit actions by our stockholders by written consent;

•

limit who may call stockholder meetings;

•

authorize our board of directors to issue preferred stock without stockholder approval, which could be used to institute a “poison pill” that would work to dilute the stock ownership of a potential hostile acquirer, effectively preventing acquisitions that have not been approved by our board of directors; and

•

require the approval of the holders of at least 75% of the voting power of all of the then-outstanding shares of capital stock that would be entitled to vote generally in the election of directors to amend or repeal specified provisions of our third amended and restated certificate of incorporation or amended and restated bylaws.

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.

If securities or industry analysts ~~do not~~ publish ~~research or reports about our business, or if they publish~~ negative evaluations of our stock or negative reports about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts. ~~We may never obtain research coverage by industry or financial analysts.~~ If ~~no or~~ few analysts commence coverage of us, the trading price of our stock would likely decrease. Even if we do obtain sufficient analyst coverage, there can be no assurance that analysts will cover us or provide favorable coverage. If one or more of the analysts who covers us downgrades our stock or changes his or her opinion of our stock, our stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our stock price or trading volume to decline.

Sales of a substantial number of shares of our common stock by our existing stockholders in the public market could cause our stock price to fall.*

Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that sales may have on the prevailing market price of our common stock.

~~Substantially~~Certain ~~all~~holders of our ~~pre-IPO~~securities ~~stockholders~~ are ~~subject~~entitled to ~~lock-up~~rights ~~agreements~~ with ~~the~~respect ~~underwriters~~to of the ~~IPO~~registration ~~that~~of ~~restrict~~ their ~~ability to transfer~~ shares ofunder ~~our common stock or securities convertible into or exercisable or exchangeable for shares of our common stock until March 31, 2020.

Sales of stock~~ by these stockholders could have a material adverse effect on the trading price of our common stock.

Certain holders of our securities are entitled to rights with respect to the registration of their shares under the Securities Act, subject to the 180-day lock-up agreements described above. Registration of these shares under the Securities Act would result in the shares becoming freely tradable without restriction under the Securities Act. Any sales of securities by these stockholders could have a material adverse effect on the trading price of our common stock.91

We have registered on Form S-8 all shares of common stock that are issuable under our ~~2018~~ Amended and Restated 2018 Equity Incentive Plan. As a consequence, these shares can be freely sold in the public market upon issuance, subject to volume limitations applicable to affiliates and the lock-up agreements described above.

We are an “emerging growth company,” and the reduced disclosure requirements applicable to emerging growth companies may make our common stock less attractive to investors.*

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. We will remain an emerging growth company until the earlier of (i) the last day of the fiscal year in which we have total annual gross revenues of $1.07 billion or more; (ii) the last day of the fiscal year following the fifth anniversary of the date of the completion of the IPO; (iii) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the Securities and Exchange Commission, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the prior June 30th. For so long as we remain an emerging growth company, we are

permitted and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. These exemptions include:

• not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act;

• not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;

• reduced disclosure obligations regarding executive compensation; and

• exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

We may choose to take advantage of some, but not all, of the available exemptions. We will continue to take advantage of these reduced reporting requirements for as long as we remain an emerging growth company. In particular, we have not included all of the executive compensation information that would be required if we were not an emerging growth company. We cannot predict whether investors will find our common stock less attractive if we rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

In addition, pursuant to the JOBS Act, as an “emerging growth company” we have elected to take advantage of an extended transition period for complying with new or revised accounting standards. This effectively permits us to delay adoption of certain accounting standards until those standards would otherwise apply to private companies. As a result, our financial statements may not be comparable to the financial statements of issuers who are required to comply with the effective dates for new or revised accounting standards that are applicable to public companies, which may make our common stock less attractive to investors.

We will incur increased costs as a result of operating as a public company, and our management will be required to devote substantial time to new compliance initiatives and corporate governance practices.

As a public company, and ~~particularly~~as ~~after~~ we are no longer an emerging growth company, we will incur significant legal, accounting and other expenses that we did not incur as a private company. The Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of the Nasdaq Stock Market and other applicable securities rules and regulations impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate governance practices. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations will increase our legal and financial compliance costs and will make some activities more time-consuming and costly. For example, we expect that these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance.

We are evaluating these rules and regulations, and cannot predict or estimate the amount of additional costs we may incur or the timing of such costs. These rules and regulations are often subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.

87Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, or the Internal Revenue Code, a corporation that undergoes an “ownership change,” is subject to limitations on its ability to use its pre-change net operating loss carryforwards, or NOLs, and other pre-change tax attributes (such as research tax credits) to offset its post-change income or taxes. For these purposes, an ownership change generally occurs where the equity ownership of one or more stockholders or groups of stockholders who owns at least 5% of a corporation’s stock increases its ownership by more than 50 percentage points over its lowest ownership percentage within a three year period. We have not determined if we have experienced Section 382 ownership changes in the past and if a portion of our NOLs is subject to an annual limitation under Section 382. We may have experienced such ownership changes in the past, and we may experience ownership changes in the future as a result of the IPO or subsequent shifts in our stock ownership, some of which are outside of our control. These ownership changes may subject our existing NOLs or credits to substantial limitations under Sections 382 and 383. Accordingly, we may not be able to utilize a material portion of our NOLs or credits. As of December 31, 2020, we had federal NOLs of approximately $270.1 million and federal and state research and development tax credit carryforwards of $21.6 million. Limitations on our ability to utilize those NOLs to offset U.S. federal taxable income could potentially result in increased future tax liability to us. In addition, at the state level, there may be periods during which the use of NOLs is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed.

To date, we have not conducted a review of our internal control for the purpose of providing the reports required by the Sarbanes-Oxley Act of 2002. Pursuant to Section 404 of the Sarbanes-Oxley Act, or Section 404, we will first be required to furnish a report by our management on our internal control over financial reporting for the year ending December 31, 2020. However, while we remain an emerging growth company, we will not be required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm. Further, a system of controls can provide only reasonable, not absolute, assurance that the control objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected. To achieve compliance with Section 404 within the prescribed period, we will be engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, potentially engage outside consultants and adopt a detailed work plan to assess and document the adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for internal control over financial reporting. Despite our efforts, there is a risk that we will not be able to conclude, within the prescribed timeframe or at all, that our internal control over financial reporting is effective as required by Section 404.

In the past, we and our independent registered public accounting firm identified two material weaknesses in our internal control over financial reporting. A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. We had determined that we had not maintained adequate formal accounting policies, processes and controls related to complex transactions as a result of a lack of finance and accounting staff with the appropriate GAAP technical expertise needed to identify, evaluate and account for complex and non-routine transactions. We had also determined that we did not maintain sufficient staffing or written policies and procedures for accounting and financial reporting, which contributed to the lack of a formalized process or controls for management’s timely review and approval of financial information. Over the last several months, we implemented a number of remedial actions to address the underlying causes of the material weaknesses, which were subject to senior management review and Audit committee oversite, including the development and formal documentation of policies and procedures relating to our internal control over financial reporting; segregation of incompatible duties and hiring of additional accounting personnel with appropriate technical accounting and financial reporting experience; and revision of our internal controls to provide a more formal process for our review procedures during the financial statement close process, and enhancement of our internal controls to identify and evaluate significant and non-routine transactions. As a result of such remedial actions, we believe we have remediated the material weaknesses.

If in the future we identify a material weakness in our internal controls over financial reporting, we may not detect errors on a timely basis and our financial statements may be materially misstated. We may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting, which could harm our operating results, cause investors to lose confidence in our reported financial information and cause the trading price of our stock to fall. In addition, as a public company we are required to file accurate and timely quarterly and annual reports with the SEC under the Exchange Act. Any failure to report our financial results on an accurate and timely basis could result in sanctions, lawsuits, delisting of our shares from The Nasdaq Global Select Market or other adverse consequences that would materially harm our business. In addition, we could become subject to investigations by the stock exchange on which our securities are listed, the SEC, and other regulatory authorities, and become subject to litigation from investors and stockholders, which could harm our reputation and our financial condition, or divert financial and management resources from our core business.

Our ability to use our net operating loss carryforwards and certain other tax attributes to offset future taxable income may be limited.*

Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, or the Internal Revenue Code, a corporation that undergoes an “ownership change,” is subject to limitations on its ability to use its pre-change net operating loss carryforwards, or NOLs, and other pre-change tax attributes (such as research tax credits) to offset its post-change income or taxes.

These ownership changes may subject our existing NOLs or credits to substantial limitations under Sections 382 and 383. Accordingly, we may not be able to utilize a material portion of our NOLs or credits. As of December 31, 2019, we had federal NOLs of approximately $114.6 million. Limitations on our ability to utilize those NOLs to offset U.S. federal taxable income could potentially result in increased future tax liability to us. In addition, at the state level, there may be periods during which the use of NOLs is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed.

Because we do not anticipate paying any cash dividends on our capital stock in the foreseeable future, capital appreciation, if any, will be your sole source of gain.

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all of our future earnings, if any, to finance the growth and development of our business. In addition, the terms of any future debt agreements may preclude us from paying dividends. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.

Pursuant to our third amended and restated certificate of incorporation, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Chancery Court does not have jurisdiction, the federal district court for the District of Delaware or other state courts of the State of Delaware) will be the sole and exclusive forum for state law claims for (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a claim of breach of a fiduciary duty by any of our directors, officers, employees or agents to us or our stockholders; (iii) any action asserting a claim against us or any of our current or former directors, officers or employees arising pursuant to any provision of the Delaware General Corporation Law or our third amended and restated certificate of incorporation or amended and restated bylaws; (iv) any action to interpret, apply, enforce or determine the validity of our third amended and restated certificate of incorporation or amended and restated bylaws; (v) any action as to which the Delaware General Corporation Law confers jurisdiction to the Court of Chancery of the State of Delaware; or (vi) any action asserting a claim governed by the internal affairs doctrine. This exclusive forum provision will not apply to any causes of action arising under the Securities Act or the Exchange Act. The forum selection clauses in our third amended and restated certificate of incorporation may limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us.

We believe our facilities are adequate for our current needs and that suitable additional substitute space would be available if needed.

Item 3. Legal Proceedings.

From time to time, we may become involved in litigation or other legal proceedings. We are not currently a party to any litigation or legal proceedings that, in the opinion of our management, are likely to have a material adverse effect on our business.

Any future determination to declare and pay dividends will be made at the discretion of our board of directors and will depend on various factors, including applicable laws, our results of operations, our financial condition, our capital requirements, general business conditions, our future prospects and other factors that our board of directors may deem relevant. Our ability to pay cash dividends on our capital stock in the future may also be limited by the terms of any preferred securities we may issue or agreements governing any additional indebtedness we may incur. Investors should not purchase our common stock with the expectation of receiving cash dividends.

Recent Sales of Unregistered Equity Securities

We did not sell any of our unregistered securities during the three months ended December 31, ~~2019~~2020.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated financial statements and related notes appearing elsewhere in this Annual Report on Form 10-K ~~and our final prospectus for our initial public offering filed pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended, or the Securities Act, on October 4, 2019, or the Prospectus~~. Some of the information contained in this discussion and analysis or set forth elsewhere in this Form 10-K, including information with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Risk Factors” section of this Form 10-K, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Investors and others should note that we routinely use the Investor Relations section of our website to announce material information to investors and the marketplace. While not all of the information that we post on the Investor Relations section of our website is of a material nature, some information could be deemed to be material. Accordingly, we encourage investors, the media, and others interested in us to review the information that it shares on the Investor Relations section of our website, www.vielabio.com.

Overview

We are a ~~clinical-stage~~ biotechnology company pioneering treatments for autoimmune ~~disease~~and severe inflammatory diseases, which we collectively refer to as autoimmune diseases. Our approach seeks to redefine the treatment of autoimmune diseases by focusing on critical biological pathways shared across multiple indications. We believe that this approach, which targets the underlying molecular pathogenesis of the disease, allows us to develop more precise therapies, identify patients more likely to respond to treatment and pursue multiple ~~diseases~~indications for each of our product candidates. Our lead ~~product candidate~~molecule, inebilizumab, is a humanized monoclonal antibody, or mAb, designed to target CD19, a molecule expressed on the surface of a broad range of immune system B cells. In January 2019, we reported positive pivotal clinical trial data for inebilizumab in patients with neuromyelitis optica spectrum disorder, or NMOSD. NMOSD is a rare, devastating condition that attacks the optic nerve, spinal cord and brain stem, and often leads to irreversible blindness and paralysis. We received Breakthrough Therapy Designation for the treatment of this disease from the U.S. Food and Drug Administration, or the FDA, in April 2019 and in August 2019, the FDA accepted for review our Biologics License Application, or BLA for inebilizumab. ~~The~~On ~~FDA set a PDUFA date of~~ June 11, 2020~~. In addition~~, wethe ~~have~~FDA aapproved ~~broad pipeline of two additional clinical~~Uplizna® (inebilizumab-~~stage~~cdon) ~~and~~for ~~two~~the ~~pre-clinical~~treatment ~~product candidates focused on a number~~ of ~~other~~adult ~~autoimmune~~patients ~~diseases~~ with ~~high~~NMOSD ~~unmet~~who ~~medical~~are ~~needs, including myasthenia gravis, IgG4~~anti-~~related~~AQP4 ~~disease,~~antibody ~~Sjögren’s~~positive ~~syndrome and lupus,~~ as ~~well~~a astwice-a-year ~~other~~maintenance ~~conditions~~regimen ~~such~~following asinitial ~~kidney transplant rejection~~doses. AWe ~~Phase~~commercially 2blaunched ~~trial~~Uplizna® following inFDA ~~Sjögren’s~~approval ~~syndrome, which is designed as Phase 3-enabling, is ongoing and~~ in ~~2019,~~June we2020 ~~initiated a separate Phase 2 trial in kidney transplant rejection.~~

Regulatory applications have also been filed in several other countries for inebilizumab in patients with NMOSD, based on results from the N-MOmentum trial. In October 2020, a BLA was accepted by the National Medical Products Administration in China. In June and September 2020, respectively, a marketing authorization application, or MAA, was filed in Japan and South Korea, and an MAA was filed with the European Medicines Agency, or EMA, in December 2020. If approved, Mitsubishi Tanabe Pharma Corporation (“MTPC”) and Hansoh Pharma, our partners in Asia, will be responsible for commercializing inebilizumab in their respective territories, and we will be eligible for payments based on certain commercial milestones, as well as royalties on sales revenue.

We incorporated on December 11, 2017 under the laws of the State of Delaware. From December 11, 2017 to December 31, 2017 we had no substantive operations. In February 2018, we acquired six molecules from MedImmune, of which five constitute our current product candidates, for a purchase price of approximately $142.3 million financed by AstraZeneca’s purchase of our Series A preferred stock. Following the asset purchase, we entered into several agreements with AstraZeneca and MedImmune, including a license agreement, a master supply and development services agreement, sublicense agreements, a transition services agreement, a clinical supply agreement and a commercial supply agreement.

To date, we have devoted substantially all of our resources to organizing and staffing our company, business planning, raising capital, identifying and developing product candidates, enhancing our intellectual property portfolio, undertaking research, conducting pre-clinical studies and clinical trials, conducting pre-commercial and commercial launch activities, and securing manufacturing for our development programs. We do not have any products approved for sale and have not generated any revenue from product sales. To date, we have funded our operations primarily with proceeds from private placement of convertible preferred stock and the IPO. In October 2019, we completed the IPO and issued and sold an aggregate 9,085,000 shares of common stock, which included 1,185,000 shares of our common stock issued pursuant to the underwriters’ option to purchase additional shares, at a public offering price of $19.00 per share, for net proceeds of $156.9 million after deducting underwriting discounts and commissions and other offering costs.

We have incurred significant operating losses since our inception, which are mainly attributed to research and development costs and employee payroll expense included in general and administrative expenses. Our net loss was $86.4 million and $190.3 million for the years ended December 31, 2019 and 2018 respectively. Our operating losses may fluctuate significantly from quarter-to-quarter and year-to-year as a result of several factors, including the timing of our pre-clinical studies and clinical trials and our expenditures related to other research and development activities. We expect to continue to incur operating losses for the foreseeable future. We anticipate these losses will increase substantially as we advance our product candidates through pre-clinical and clinical development, develop additional product candidates and seek regulatory approvals for our product candidates. We do not expect to generate any revenues from product sales unless and until we successfully complete development and obtain regulatory approval for one or more product candidates. In addition, if we obtain marketing approval for any product candidate, we expect to incur pre-commercialization expenses and significant commercialization expenses related to marketing, sales, manufacturing and distribution. We may also incur expenses in connection with the in-licensing of additional product candidates. 97

In June 2020, the Company completed an underwritten public offering of its common stock and issued and sold 3,600,000 shares of common stock, at a public offering price of $47.00 per share, for aggregate gross proceeds of $169,200 and net proceeds after deducting underwriting discounts and commissions and other offering costs of $158,338.

We have incurred significant operating losses since our inception, which are mainly attributed to research and development costs and employee payroll expense included in general and administrative expenses. Our net loss was $150.7 million, $86.4 million and $190.3 million for the years ended December 31, 2020, 2019, and 2018, respectively. Our operating losses may fluctuate significantly from quarter-to-quarter and year-to-year as a result of several factors, including the timing of our pre-clinical studies and clinical trials, our expenditures related to other research and development activities, and revenue generated from product sales and licensing agreements. We expect to continue to incur operating losses for the foreseeable future. We anticipate these losses will increase substantially as we advance our product candidates through pre-clinical and clinical development, develop additional product candidates and seek regulatory approvals for our product candidates. We expect to incur pre-commercialization expenses and significant commercialization expenses related to marketing, sales, manufacturing and distribution for any product candidate that obtain marketing approval. We may also incur expenses in connection with the in-licensing of additional product candidates. Furthermore, we expect to incur additional costs associated with operating as a public company, including significant legal, accounting, investor relations, compliance and other expenses that we did not incur as a private company.

As a result, in the event the Merger (defined below) and related transactions do not close and we remain a stand-alone company, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time as we can generate significant revenue from sales of our product candidates, if ever, we expect to finance our cash needs through public or private equity offerings, debt financings, collaborations and licensing arrangements or other capital sources. However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at all. Our failure to raise capital or enter into such other arrangements as and when needed would have a negative impact on our financial condition and could force us to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market our product candidates that we would otherwise prefer to develop and market ourselves.

In December 2019 an outbreak of a novel strain of coronavirus was identified in Wuhan, China. This virus continues to spread globally, has been declared a pandemic by the World Health Organization and has spread to over ~~100~~200 countries, including the United States. The impact of this pandemic has been and will likely continue to be extensive in many aspects of society, which has resulted in and will likely continue to result in significant disruptions to businesses and capital markets around the world. The extent to which the coronavirus impacts us will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the coronavirus and the actions to contain the coronavirus or treat its impact, among others. At present, we are not experiencing significant impact or delays from COVID-19 on our business, ~~operations~~ and, ~~if approved, commercialization plans~~operations. However, in order to prioritize patient health and that of the investigators at clinical trial sites, we ~~have~~had paused enrollment of new patients ~~for four weeks~~ in certain of our clinical trials, including our Phase 2b trial of VIB4920 in ~~Sjogren~~Sjögren’s syndrome, our Phase 2 trial of VIB4920 in ~~kidney~~rheumatoid ~~transplant~~arthritis ~~rejection,~~ and our Phase 2 trial of inebilizumab in kidney transplant desensitization. We recently resumed our Phase 2b trial of VIB4920 in Sjögren’s syndrome and our Phase 2 trial of VIB4920 in rheumatoid arthritis. Our ability to re-open enrollment, and continue enrollment, in any paused clinical trials will be dependent on many factors, including the progression of the pandemic and its impact on patients and the investigators at our clinical trial sites. Furthermore, our ability to re-open enrollment, and continue enrollment, in each of these paused clinical trials will require collaboration with, and permission from, each of the clinical trial sites. Over the coming weeks and months, we will continue to monitor carefully the situation with respect to each of our clinical trials and follow guidance from local and federal health authorities. Additionally, with respect to our commercial launch of Uplizna®, we believe that the pandemic has resulted in a decrease in patient visits to prescribing physicians, as well as challenges in coordination and communication between patients and prescribing physicians. Furthermore, we believe some prescribing physicians are reluctant to change existing treatment regimens for patients, except in the event of significant need, without first meeting patients in-person prior to making such a change. The ongoing pandemic has led to increased challenges in having in-person meetings between patients and prescribing physicians. We believe these factors are adversely impacting, and may continue to adversely impact for the duration of the pandemic, the number of new prescriptions written for Uplizna®. We plan to continue to adapt our commercialization efforts to address the uncertainty presented by this treatment environment.

Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we are able to generate product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations.

In May 2019, we entered into a license and collaboration agreement with Hansoh Pharma, for co-development and commercialization of inebilizumab in China, Hong Kong, and Macau for NMOS as well as other potential inflammation/autoimmune and hematologic malignancy diseases. Under the terms of the agreement, we received up-front licensing fees of an aggregate of $20 million and may receive payments contingent on certain development, regulatory and commercial milestones, for up to an aggregate of $203 million, plus royalties on net sales ranging from low double-digits to high teens.98

We will be responsible for supplying inebilizumab~~ to ~~Hansoh~~reduce ~~Pharma~~or ~~pursuant~~terminate toour ~~a supply agreement that we expect to enter into~~operations.

InMerger ~~October 2019, we entered into the MTPC License~~ Agreement with MTPC for co-development and commercialization of inebilizumab in the MTPC Territory for NMOSD as well as other indications that we and MTPC mutually agree to add to the MTPC License Agreement. Under the terms of the MTPC License Agreement, we are eligible to receive up-front licensing fees of an aggregate of $30.0 million which has been recorded as accounts receivable on the balance sheet as of December 31,2019, as well as development and commercialization milestones and payments based, in part, on sales revenue. In January 2020, we received the upfront payment of $30.0 million.

The Offer and the Merger are not subject to any financing condition.

Between February 18, 2021 and February 26, 2021, five of our purported stockholders filed separate lawsuits against us and our directors. Three of the lawsuits were filed in the federal district court for the Southern District of New York, one was filed in the federal district court for District of Delaware, and one in the federal district court for the Eastern District of Pennsylvania. The complaints allege violations of certain sections of the Exchange Act. All five lawsuits allege that the Schedule 14D-9 Solicitation/Recommendation Statement that we filed on February 12, 2021 (“14D-9”) is materially incomplete and misleading and seek to enjoin the tender offer until the purported deficiencies in the 14D-9 are corrected, or alternatively, monetary damages if the tender offer is consummated. The defendants believe the claims asserted in the complaints are without merit. Additional lawsuits arising out of or relating to the tender offer may be filed in the future.

We expect the Merger to close during the first quarter of 2021, subject to the regulatory approvals and other customary closing conditions described above and in the Merger Agreement.

Additional information about the Merger and related transactions is set forth in our filings with the Securities and Exchange Commission, or the SEC.

Components of our Results of Operations

Revenue

We ~~have~~did not ~~generated~~generate any revenue from the sale of products since our inception ~~and~~through doJune ~~not~~30, ~~expect~~2020. toWe ~~generate~~initiated ~~substantial~~the commercial launch of Uplizna® and generated revenue from the sale of products in the ~~near~~third ~~future,~~and iffourth atquarters ~~all~~of 2020. We have also generated revenue from commercial license and collaboration agreements related to the treatment of NMOSD with inebilizumab. In addition, if our development efforts for our product portfolio, including inebilizumab, are successful and result in marketing approval or if we enter into collaboration or license agreements with third parties, we may generate revenue in the future from product sales or payments from such collaboration or license agreements, or a combination of product sales and payments from such agreements.

NMOSD with inebilizumab. We do not expect any revenues that we may generate in the near future to be significant enough to fund our operations. We generated $50 million of license revenue in 2019.

In connection with the license agreement with Mitsubishi Tanabe Pharma Corporation, or MTPC, dated October 8, 2019, we entered into a supply agreement with MTPC, pursuant to which, among other things, we will supply products for MTPC’s commercial use. Under the supply agreement, MTPC provides a rolling forecast for a period of 36 months of its usage for product. Payment is based on the forecasted usage of supplied product and becomes due following delivery of product and invoicing by the Company. Changes in demand from MTPC and any adjustments to MTPC’s forecasted usage requirements of inebilizumab may cause our revenue and net loss to fluctuate significantly from period-to-period, which may result in a high degree of variability in our results of operations.

Cost of Product Sold

Cost of product sales includes the cost of producing and distributing inventories that are related to product revenues during the respective period, and third-party royalties payable on our net product revenues. Cost of goods sold also includes, as applicable, costs related to excess or obsolete inventory adjustment charges, abnormal costs, unabsorbed manufacturing and overhead costs, amortization of intangible asset, and manufacturing variances. We presently expect to have a lower cost of product sold until 2023.

Research and Development Expenses

To date, our research and development expenses, net of the acquisition of IPR&D that is disclosed separately, have related primarily to development of inebilizumab, VIB4920 and VIB7734, pre-clinical studies and other pre-clinical activities related to our portfolio. Research and development expenses are recognized as incurred, and payments made prior to the receipt of goods or services to be used in research and development are capitalized until the goods or services are received.

Research and development expenses include:

•

salaries, payroll taxes, employee benefits, and stock-based compensation charges for those individuals involved in research and development efforts;

•

external research and development expenses incurred under agreements with contract research organizations and consultants to conduct our pre-clinical, toxicology and other pre-clinical studies, as well as clinical trials of our product candidates;

•

laboratory supplies;

•

costs related to manufacturing product candidates, including fees paid to third-party manufacturers and raw material suppliers;

•

license fees and research funding; and

•

facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent, maintenance of facilities, insurance, equipment and other supplies.

~~Clinical~~We trial costs are a significant component of research and development expenses and include costs associated with third-party contractors. A majority of these payments are pass-through payments that are made to MedImmune and AstraZeneca pursuant to the existing contracts in place associated with the IPR&D assets acquired (see Note 8, "Asset acquisition" for additional information). Through our agreements with MedImmune and AstraZeneca, we outsource a substantial portion of our clinical trial activities, utilizing external entities such as CROs, independent clinical investigators and other third-party service providers to assist us with the execution of our clinical trials. We also expect to incur additional expenses related to milestone and royalty payments payable to third parties with whom we have entered into license agreements relating to our product candidates.

We plan to substantially increase our research and development expenses for the foreseeable future, as we continue the development of our product candidates and seek to discover and develop new product candidates. Due to the inherently unpredictable nature of pre-clinical and clinical development, we cannot determine with certainty the timing of the initiation, duration or costs of future clinical trials and pre-clinical studies of product candidates. Clinical and pre-clinical development timelines, the probability of success and the amount of associated development costs can differ materially from expectations. We anticipate that we will make determinations as to which product candidates and development programs to pursue and how much funding to direct to each product candidate or program on an ongoing basis in response to the results of ongoing and future pre-clinical studies and clinical trials, regulatory developments and our ongoing assessments as to each product candidate’s commercial potential. In addition, we cannot forecast which product candidates may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and capital requirements.

100

Our future clinical development costs may vary significantly based on factors such as:

•

per patient trial costs;

•

the number of patients needed to determine a recommended dose;

•

the number of trials required for regulatory approval;

•

the number of sites included in the trials;

•

the countries in which the trials are conducted;

•

the length of time required to enroll eligible patients;

•

the number of patients who participate in the trials;

•

the number of doses that patients receive;

•

the drop-out or discontinuation rates of patients;

•

potential additional safety monitoring requested by regulatory agencies;

•

the duration of patient participation in the trials and follow-up;

•

the phase of development of the product candidate;

•

the efficacy and safety profile of the product candidate; and

•

developments related to the coronavirus outbreak and impact of it and COVID-19 on the costs and timing associated with the conduct of our clinical trials and other related activities.

Selling, General and Administrative Expenses

~~General~~Selling, general and administrative expenses consist primarily of salaries and employee-related costs, including stock-based compensation for personnel in our executive, finance and other administrative functions. Other significant costs include ~~facility and/or rent-related costs,~~ legal fees relating to intellectual property and corporate matters, professional fees for accounting and consulting services, facility and/or rent-related costs, and insurance costs. We anticipate that our general and administrative expenses will increase in the future to support our continued research and development activities, ~~pre-commercialization~~ and, ~~if any product candidates receive marketing approval,~~ commercialization activities. We also anticipate increased expenses related to audit, legal, regulatory and tax-related services associated with maintaining compliance with stock exchange listing and SEC requirements, director and officer insurance premiums and investor relations costs associated with operating as a public company.

Acquisition of In-Process Research and Development

Acquisition of IPR&D represents the expense recognized related to the Asset Purchase Agreement with AstraZeneca and MedImmune (the “APA”). The six molecules we acquired from MedImmune pursuant to the APA consist of multiple IPR&D projects related to biological therapies which are intended to treat an interrelated subset of autoimmune disorders, represented in part by common biological characteristics. See Note 89, "“Asset acquisition"” for further information.

Interest Income

Interest income consists of interest earned on our cash and cash equivalents and marketable securities.
