Our ~~Business~~lead ~~Overview~~development product, MVT-5873, is a fully human IgG1 monoclonal antibody (mAb) that targets sialyl Lewis A (sLea), an epitope on CA19-9. MVT-5873 is currently in Phase 1 clinical trials as a therapeutic agent for patients with pancreatic cancer and other CA19-9 positive tumors. CA19-9 is expressed in over 90% of pancreatic cancers and in other diseases including pancreatitis. CA19-9 plays an important role in tumor adhesion and metastasis and is a marker of an aggressive cancer phenotype. CA19-9 also has an important role in the biological pathways that can result in pancreatitis. CA19-9 serum levels are considered a valuable adjunct in the diagnosis, prognosis and treatment monitoring of pancreatic cancer and now pancreatitis. With our collaborators including MSK, Sarah Cannon Research Institute, Honor Health and Imaging Endpoints, we have treated more than 56 patients with either our therapeutic antibody designated as MVT-5873 or our PET imaging diagnostic product designated as MVT-2163 in Phase 1 clinical studies, and demonstrated early safety, specificity for the target and a potential efficacy signal. The Company also has a radioimmunotherapy product, designated as MVT-1075, that is also in Phase 1 clinical development. For additional information, please visit the Company's website, www.mabvax.com.

~~Our~~Plan lead clinical development program is a Phase 1 clinical trial of our HuMab-5B1 radioimmunotherapy (“RIT”) product that we have designated as MVT-1075. The development of MVT-1075 is based on experience we gained through clinical studies of over 50 patients with either our antibody we designate as MVT-5873, or our imaging agent we designate as MVT-2163 that are discussed in more detail in our descriptions and results to date of our clinical development programs. We initiated the Phase 1 clinical trial of MVT-1075 in June 2017 and completed enrollment and dosing of the last patient in the initial cohort of patients in December 2017. The clinical program is intended to evaluate the product for ~~the~~Remainder ~~treatment~~ of ~~pancreatic,~~ colon and lung cancer. The primary objective is to determine the maximum tolerated dose in patients who have failed prior therapies. Secondary endpoints include evaluating tumor response rate and duration of response by RECIST 1.1, and to determine dosimetry and pharmacokinetics. This dose-escalation study utilizes a traditional 3+3 design. We expect to receive and report on interim safety data and tumor assessment using standard RECIST measurement criteria for cohort 1 in the first quarter 2018.

Based on the experience with recent asset sales and license agreements, and continuing inquiries from third parties regarding their interest in other MabVax assets and clinical progress to date related to MVT-5873, MVT-1075, and MVT-2163, we intend on continuing to explore additional licensing and/or collaboration opportunities for certain fields of use of our technology. However, there can be no assurance that any such transaction will occur.

WeIf ~~also~~we ~~intend~~are toable continue clinical development of the antibody MVT-5873 in combination with gemcitabine and nab-paclitaxal in first line therapy for the treatment of patients newly diagnosed with pancreatic cancer. We have treated two cohorts of patients in our combination therapy, for a total of six patients to ~~date~~secure inadditional ~~this study.

On September 6, 2017, we announced that we have engaged Greenhill & Co. (NYSE: GHL) to serve as a financial advisor to assist us in exploring and evaluating strategic options with the goal of maximizing stockholder value. We have received and are evaluating several inbound inquiries and transaction options, as well as identifying new opportunities which could include the acquisition of MabVax by another company, the sale or divestiture of specific assets coupled with a reverse merger, merging with another company, or licensing of selected technologies. We do not have a defined timeline for the exploration of strategic alternatives, as we are still receiving inquiries, and are not confirming that the evaluation will result in any strategic alternative being announced or consummated. We do not intend to discuss or disclose further developments during this process unless and until our Board of Directors has approved a specific action or otherwise determined that further disclosure is appropriate. While Greenhill & Co. continues as our financial advisor, we will continue to advance our Phase 1 clinical programs including our MVT-1075 radioimmunotherapy clinical trial for the treatment of pancreatic, colon and lung cancers, and our MVT-5873 clinical trial in combination with one or more chemotherapy agents in first line therapy for patients newly diagnosed with pancreatic cancer.●

Our primary business strategy is to develop our early antibody product candidates through proof of concept clinical trials, which may represent either phase I or phase II clinical trials depending on the program and extent of progress. Once through proof of concept clinical trials, we will decide whether to license, partner or sell those product candidates, or continue to develop the candidates depending on several variables such as access to additional capital, cost of later stage clinical trials, risk of such development efforts, and the value derived from licensing, partnering or selling those assets.●

We have submitted our Investigational New Drug Application (“IND”), to the FDA, for a revised protocol to enable continuation of the trial at higher doses.

MVT-1075 combines the demonstrated targeting specificity of the HuMab-5B1 antibody with the proven clinical success of a low-energy radiation emitter, 177Lutetium [177Lu]. We dosed MVT-1075 in our first patient in June 2017. This Phase 1 first-in-human clinical trial is an open-label, multi-center study evaluating the safety and efficacy of MVT-1075 in up to 22 patients with CA19-9 positive malignancies. The primary objective is to determine the maximum tolerated dose and safety profile in patients with recurring disease who have failed prior therapies. Secondary endpoints are to evaluate tumor response rate and duration of response by RECIST 1.1, and to determine dosimetry and pharmacokinetics. This dose-escalation study utilizes a traditional 3+3 design that is commonly used by companies as a dose escalation strategy typical for phase I trials for the treatment of cancer. The investigative sites are Honor Health in Scottsdale, Arizona, and Memorial Sloan Kettering Cancer Center in New York City.●

We reported results from our Phase 1a clinical trial of ImmunoPET imaging agent, MVT-2163, in 12 patients with locally advanced or metastatic adenocarcinoma of the pancreas (PDAC) or other CA19-9 positive malignancies in a poster presentation and podium talk at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) Annual Meeting held in Denver, CO on June 10-14, 2017.

The Phase Ia clinical trial of MVT-2163 phase I trial was intended to evaluate our next generation diagnostic PET imaging agent in patients with locally advanced or metastatic adenocarcinoma of the pancreas (PDAC) or other CA19-9 positive malignancies. MVT-2163 (89Zr-HuMab-5B1) combines the well-established PET imaging radiolabel Zirconium-89 [89Zr] with the targeting specificity of MVT-5873. We designed the trial to establish safety, pharmacokinetics, biodistribution, optimal time to obtain the PET image, and the amount of MVT-5873 to be administered as a blocking dose prior to administration of MVT-2163 to obtain optimized PET scan images.

As of July 2017, 12 patients had been treated in this first-in-human trial evaluating the safety and feasibility of MVT-2163 to image pancreatic tumors and other CA19-9 positive malignancies. MVT-2163 was administered alone and in combination with MVT-5873 and was well tolerated in all cohorts. The only toxicities were infusion reactions that resolved on the day of the injection, with some patients requiring standard supportive medication.

Uptake of MVT-2163 was observed in primary tumors and metastases as early as day two and continuously through day seven. Standard Uptake Values (SUV), a measurement of activity in PET imaging, reached as high as 101 in the study. The investors reported that the high SUVs are amongst the highest lesion uptake values they have ever seen for a radiolabeled antibody. Bone and soft tissue disease were readily visualized and lesion uptake of the radiotracer was higher than typically seen with PET imaging agents. The correlation with Computerized Tomography (CT) scans was high.

In accordance with the Registration Rights Agreement, on November 20, 2018, we filed the registration statement of which this prospectus is a part registering the resale by Triton of up to 6,000,000 shares that may be issued, which represents shares of common stock issuable upon conversion of Series P Preferred Stock and sold to Triton under the Triton Offering, and the resale by Triton Funds LLC of 175,000 shares of common stock we agreed to issue upon execution of the Equity Purchase Agreement to support the cost of the student-run fund.

On August 2, 2016, the Board approved a 1-for-7.4 reverse stock split, or the “Listing Reverse Split.” The Listing Reverse Split was intended to allow us to meet the minimum share price requirement of the NASDAQ Capital Market. On August 11, 2016, we received approval from the NASDAQ Capital Market for the listing of our common stock under the symbol “MBVX”, subject to implementation of the Listing Reverse Split and closing of our August 2016 public offering (the “August 2016 Public Offering”). On August 16, 2016, we implemented the Listing Reverse Split, closed on the August 2016 Public Offering and began trading on the NASDAQ Capital Market at the open of business on August 17, 2016. Unless otherwise stated herein, all per share amounts herein give effect to the Listing Reverse Split.

Recent Events

July 2017 Private Placement – On July 27, 2017, we entered into a subscription agreement with an accredited investor pursuant to which we agreed to sell 152,143 restricted shares of common stock for $125,000 (the “July 2017 Private Placement”). As part of the transaction, the Company agreed to reprice the investor’s warrant to purchase 225,225 shares of common stock from $11.10 to $2.00 per warrant share and remove the cashless exercise feature. The transaction closed on August 2, 2017. The impact of repricing the warrants to $2.00 a share, which took effect on August 2, 2017, was immaterial, as the stock price on the date of the closing of the transaction was $0.70 and the warrants at $2.00 a share expired on October 10, 2017, unexercised.

~~August 11, 2017 Registered~~ ~~Direct~~RISK Offering – On August 11, 2017, we entered into securities purchase agreements to sell 2,386.36 shares of Series J Preferred Stock with a stated value of $550 per share (the “August 2017 Offering”). The Series J Preferred Stock is convertible into common stock at $0.55 per share, subject to adjustment for stock splits, stock dividends, recapitalizations, combinations, subdivisions or other similar events and was purchased by certain existing investors of the Company (the “Prior Investors”).

● In addition to the potential material impact on our ability to raise capital, the expense of responding to matters relating to the SEC Action, and on behalf of those individuals whom we may be obligated to indemnify and defend in connection with the SEC Action, may exceed our available resources. Further, these expenses may not be covered by our existing insurance, and even where coverage exists, may require exhaustion of self-insured retentions or deductibles that could exceed the cash currently available to the Company. At this time, we cannot predict how the SEC Action, Complaint or any related matters may impact the market for our common stock or the perceptions of potential partners and investors considering a transaction with the Company. To the extent the market, potential investors or potential partners have a negative perception of us during the pendency of the SEC Action, the price of our common stock may be negatively affected, and potential partners and investors may be less likely to transact business with us.

~~Lead~~The SEC ~~Investor~~has informed the Company that it will ~~commit~~not declare certain registration statements previously filed effective during the pendency of the SEC Action.

In ~~order~~Information towe ~~meet~~have ~~the~~learned ~~NASDAQ Capital Market rules~~ in ~~the~~connection ~~August~~with ~~2017 Offering, we were not obligated to issue any shares of common stock upon conversion of~~ the ~~Series~~SEC JAction ~~Preferred Stock which would cause~~has ~~the~~placed ~~Company~~doubt to breach our obligations under the rules and regulations of the NASDAQ Capital Market, which limit the aggregate number of shares issued at a discount to market at 19.99% of the number of shares outstanding on the ~~closing~~reporting ~~date~~ of ~~the~~beneficial ~~August~~ownership ~~2017 Offering,~~by ~~except~~several ~~that such limitation shall not apply in the event that we obtain the approval~~ of our stockholders, ascreating ~~required~~uncertainty ~~by the applicable rules~~ of ~~the~~whether ~~NASDAQ~~we ~~Capital~~will ~~Market~~ever ~~for issuances of~~be ~~common~~able ~~stock~~to inrely ~~excess~~on of such ~~amount.

We believe that ~~relating~~significant facts and circumstances were known by our former outside counsel but were not disclosed to the Company. The Company has reason to believe that beneficial ownership and other information reported by certain outside investors, that includes the Company’s ~~registered~~former ~~direct~~outside ~~offering~~counsel, is not accurate and ~~issuance~~complete, and ~~sale~~that the members of 2the Aggregated Investors have failed to properly report their beneficial ownership and other matters on SEC Schedules 13D or 13G,~~016,129~~ ~~shares~~or ofotherwise.

The purchase price per share was $0.65. The total amount of the subscription agreements amounted to $500,000, before estimated expenses of $15,000. The securities were offered by means of the Company’s shelf registration statement on Form S-3 (File #333-219291) which was declared effective on July 27, 2017 by the Securities and Exchange Commission.Condition

We will be required to raise additional funds to finance our operations and remain a going concern; we may not be able to do so when necessary, and/or the terms of any financings may not be advantageous to us, requiring cutbacks in personnel or sale of assets below their potential value.

Our operations to date have consumed substantial amounts of cash. Negative cash flows from our operations are expected to continue over at least the next several years. Our ongoing capital requirements will depend on numerous factors, including: the progress and results of preclinical testing and clinical trials of our product candidates under development; the costs of complying with the FDA and other domestic and foreign regulatory agency requirements, the progress of our research and development programs and those of our partners; the time and costs expended and required to obtain any necessary or desired regulatory approvals; the resources that we devote to manufacturing expenditures; our ability to enter into licensing arrangements, including any unanticipated licensing arrangements that may be necessary to enable us to continue our development and clinical trial programs; the costs and expenses of filing, prosecuting and, if necessary, enforcing our patent claims, or defending against possible claims of infringement by third-party patent or other technology rights; the cost of commercialization activities and arrangements, if any, that we undertake; and, if and when approved, the demand for our products, which demand depends in turn on circumstances and uncertainties that cannot be fully known, understood or quantified unless and until the time of approval, including the range of indications for which any product is granted approval, and legal costs associated with the SEC Action and other litigation matters. If we are unable to enter into additional asset sales and license agreements or raise additional capital, then we may have to substantially curtail our clinical trials which could slow the progress in the development of our product candidates. In addition, the further development of our product candidates and ongoing clinical trials will depend on upcoming analysis and results of those trials and our financial resources at the time of these results.

As of December 31, 2017, we had an outstanding principal balance of approximately $3.6 million. The option to draw the ~~Company~~second $5 million expired on September 30, 2016. The loan and security agreement contains customary affirmative and negative covenants and events of default. The affirmative covenants include, among others, covenants requiring us to maintain our legal existence and governmental approvals, deliver certain financial reports and maintain insurance coverage. The negative covenants include, among others, restrictions on transferring collateral, changing our business, incurring additional indebtedness, engaging in mergers or acquisitions, paying dividends or making other distributions, making investments and creating other liens on our assets, in each case subject to customary exceptions. On August 14, 2018, Oxford Finance gave notice asserting that certain events of default have occurred and are continuing under their loan agreement with us. In the ~~holders~~notice, Oxford Finance does not specify which provisions of the loan agreement are allegedly implicated by each of the alleged default events, stating only generally its position that events of default have occurred or may have occurred. The Company informed Oxford Finance that it disputes the alleged default events, individually or collectively, constitute a “Material Adverse Change” or other event of default as those terms are defined in the loan agreement, as further described on ~~October~~Page 1863. Defaults Upon Senior Securities, ~~2017~~on Page F-14.

RISK FACTORS

Any investment in our securities involves a high degree of risk. Investors should carefully consider the risks described below and all of the information contained in this prospectus before deciding whether to purchase our securities. Our business, financial condition and results of operations could be materially adversely affected by these risks if any of them actually occur. This prospectus also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks we face as described below and elsewhere in this prospectus.

Risks Relating to Our Financial Condition

Our operations to date have consumed substantial amounts of cash. Negative cash flows from our operations are expected to continue over at least the next several years. Our cash utilization amount is highly dependent on the progress of our product development programs, particularly, the results of our preclinical and clinical studies and those of our partners, the cost, timing and outcomes of regulatory approval for our product candidates, and the rate of recruitment of patients in our human clinical trials. In addition, the further development of our ongoing clinical trials will depend on upcoming analysis and results of those studies and our financial resources at that time.

Although we have raised approximately $4,900,000, net of offering costs, since June 30, 2017, for various financings and offerings, we will require future additional capital infusions including public or private financing, strategic partnerships or other arrangements with organizations that have capabilities and/or products that are complementary to our own capabilities and/or products, in order to continue the development of our product candidates. At present, we have sufficient cash to fund operations until February 2018 assuming we do not complete any strategic or financing transactions between now and February 2018. We are exploring and evaluating strategic options with the goal of maximizing stockholder value, and currently working with our financial advisor Greenhill & Co., to assist us with our efforts.

Our ongoing capital requirements will depend on numerous factors, including: the progress and results of preclinical testing and clinical trials of our product candidates under development; the costs of complying with the FDA and other domestic and foreign regulatory agency requirements, the progress of our research and development programs and those of our partners; the time and costs expended and required to obtain any necessary or desired regulatory approvals; the resources that we devote to manufacturing expenditures; our ability to enter into licensing arrangements, including any unanticipated licensing arrangements that may be necessary to enable us to continue our development and clinical trial programs; the costs and expenses of filing, prosecuting and, if necessary, enforcing our patent claims, or defending against possible claims of infringement by third-party patent or other technology rights; the cost of commercialization activities and arrangements, if any, that we undertake; and, if and when approved, the demand for our products, which demand depends in turn on circumstances and uncertainties that cannot be fully known, understood or quantified unless and until the time of approval, including the range of indications for which any product is granted approval. If we are unable to raise additional capital, then we may have to substantially curtail our clinical trials which could slow the progress in the development of our products.

We are required to obtain the consent of an existing investor, or the Lead Investor, to certain future transactions, which may hinder our ability to obtain future financing.

We granted to the Lead Investor the right to approve future transactions that require stockholder approval under the rules of the NASDAQ Stock Market LLC or any state laws (the “Consent”). These transactions could include offerings of our securities, mergers, acquisitions, or sales of some or substantially all of our assets.

-9-

Table of Contents

Should the Consent be required in connection with future offerings, we may be required again to provide additional consideration, including, but not limited to, consideration in the form of cash and/or additional shares of our capital stock and/or securities convertible into or exercisable for shares of our capital stock, in order to obtain the Consent. If we are unable to obtain the Consent when necessary for future offerings, we may be unable to raise additional funds. An inability to raise additional funds could have a material adverse effect on our financial condition, results of operations, ability to conduct our business and on the price of our common stock.

The terms of our secured debt facility require us to meet certain operating and financial covenants and place restrictions on our operating and financial flexibility. If we raise additional capital through debt financing, the terms of any new debt could further restrict our ability to operate our business.

Effective in January 2016, we entered into a $10 million loan and security agreement with Oxford Finance LLC, or Oxford Finance, that is secured by a lien covering substantially all of our assets, excluding intellectual property. As of September 30, 2017, we had an outstanding principal balance of approximately $3.9 million. The option to draw the second $5 million expired on September 30, 2016. The loan and security agreement contains customary affirmative and negative covenants and events of default. The affirmative covenants include, among others, covenants requiring us to maintain our legal existence and governmental approvals, deliver certain financial reports and maintain insurance coverage. The negative covenants include, among others, restrictions on transferring collateral, changing our business, incurring additional indebtedness, engaging in mergers or acquisitions, paying dividends or making other distributions, making investments and creating other liens on our assets, in each case subject to customary exceptions. As of December 14, 2017, we were in compliance with all the covenants. If we default under the loan agreement, the lenders may accelerate all of our repayment obligations and take control of our pledged assets, potentially requiring us to renegotiate our agreement on terms less favorable to us or to immediately cease operations. Further, if we are liquidated, the lender’s right to repayment would be senior to the rights of the holders of our common stock and preferred stock to receive any proceeds from the liquidation. The lenders could declare a default upon the occurrence of any event that they interpret as a material adverse change as defined under the loan agreement, thereby requiring us to repay the loan immediately or to attempt to reverse the declaration of default through negotiation or litigation. Any declaration by the lenders of an event of default could significantly harm our business and prospects and could cause the price of our common stock to decline. If we raise any additional debt financing, the terms of such additional debt could further restrict our operating and financial flexibility.

We have a history of losses, and we anticipate that we will continue to incur losses in the future; our auditors have included in their audit report an explanatory paragraph as to substantial doubt as to our ability to continue as a going concern.

We have experienced net losses every year since our inception and, as of September 30, 2017, had an accumulated deficit of $101,046,557. Our auditors have included in their audit report a “going concern” explanatory paragraph as to substantial doubt as to our ability to continue as a going concern that assumes the realization of our assets and the satisfaction of our liabilities and commitments in the normal course of business. Until such time as we have completed more than one license agreement for our technology, and assuming we have sufficient funding from such licenses and financing transactions to continue to sustain operations, we anticipate continuing to incur substantial additional losses over at least the next several years due to, among other factors, expenses related to the following: continuing Phase I clinical trials with MVT-1075 as a radioimmunotherapy agent, and MVT-5873 in combination with a chemotherapy agent, for the treatment of various cancers, preclinical testing of follow-on antibody candidates, investor and public relations, SEC compliance efforts, anticipated research and development activities and the general and administrative expenses associated with each of these activities. We have not yet commercialized any product candidates. Our ability to attain profitability will depend upon our ability to enter into material revenue generating license arrangements, develop and commercialize products that are effective and commercially viable, to obtain regulatory approval for the manufacture and sale of our products and to license or otherwise market our products successfully. We may never achieve profitability, and even if we do, we may not be able to sustain being profitable. If we are unable to obtain additional capital we may be forced to license, sell or terminate our activities with respect to promising technologies which may require us to agree to disadvantageous terms that will prevent us from realizing the potential value from the results of our efforts and expenditures.

Risks Related to our Business

If we are unable to obtain required regulatory approvals, we will be unable to market and sell our product candidates.

Our product candidates are subject to extensive governmental regulations relating to development, clinical trials, manufacturing, oversight of clinical investigators, recordkeeping and commercialization. Rigorous preclinical testing and clinical trials and an extensive regulatory review and approval process are required to be successfully completed in the United States and in each foreign jurisdiction in which we offer our products before a new drug or other product can be sold in such jurisdictions. Satisfaction of these and other regulatory requirements is costly, time consuming, uncertain, and subject to unanticipated delays. The time required to obtain approval by the FDA, or the regulatory authority in such other jurisdictions is unpredictable and often exceeds five years following the commencement of clinical trials, depending upon the complexity of the product candidate and the requirements of the applicable regulatory agency.

In connection with the clinical development of our product candidates, we face risks that:

●

the product candidate may not prove to be safe and efficacious;

●

patients may die or suffer serious adverse effects for reasons that may or may not be related to the product candidate being tested;

●

we may fail to maintain adequate records of observations and data from our clinical trials, to establish and maintain sufficient procedures to oversee, collect data from, and manage clinical trials, or to monitor clinical trial sites and investigators to the satisfaction of the FDA or other regulatory agencies;

●

the results of later-phase clinical trials may not confirm the results of earlier clinical trials; and

●

the results from clinical trials may not meet the level of statistical significance or clinical benefit-to-risk ratio required by the FDA or other regulatory agencies for marketing approval.

Only a small percentage of product candidates for which clinical trials are initiated receive approval for commercialization. Furthermore, even if we do receive regulatory approval to market a product candidate, any such approval may be subject to limitations such as those on the indicated uses for which we may market a particular product candidate.-7-

Our product candidates have not completed sufficient clinical trials to obtain regulatory approval, and may never demonstrate sufficient safety and efficacy in order to do so.

Our product candidates are in the clinical and pre-clinical stages of development. In order to achieve profitable operations, we alone, or in collaboration with others, must successfully license, develop, manufacture, introduce and market our products. The time frame necessary to achieve market success for any individual product, whether we or our potential strategic partners develop, is long and uncertain. The products we are currently developing will require significant additional research, development and preclinical and clinical testing prior to application for commercial use or sale. A number of companies in the biotechnology and pharmaceutical industries have suffered significant setbacks in clinical trials, even after showing promising results in early or later-stage studies or clinical trials. Although we have obtained some favorable results to-date in preclinical studies and clinical trials of certain of our potential products, such results may not be indicative of results that will ultimately be obtained in or throughout such clinical trials, and clinical trials may not show any of our products to be safe or capable of producing a desired result. Additionally, we may encounter problems in our clinical trials that may cause us to delay, suspend or terminate those clinical trials.

Our product candidates have not completed sufficient clinical trials to obtain regulatory approval and may never demonstrate sufficient safety and efficacy in order to do so.

Our product candidates are in the clinical and pre-clinical stages of development. To achieve profitable operations, we alone, or in collaboration with others, must successfully license, develop, manufacture, introduce and market our products. The time frame necessary to achieve market success for any individual product, whether we or our potential strategic partners develop, is long and uncertain. The products we are currently developing will require significant additional research, development and preclinical and clinical testing prior to application for commercial use or sale. Several companies in the biotechnology and pharmaceutical industries have suffered significant setbacks in clinical trials, even after showing promising results in early or later-stage studies or clinical trials. Although we have obtained some favorable results to-date in preclinical studies and clinical trials of certain of our potential products, such results may not be indicative of results that will ultimately be obtained in or throughout such clinical trials, and clinical trials may not show any of our products to be safe or capable of producing a desired result. Additionally, we may encounter problems in our clinical trials that may cause us to delay, suspend or terminate those clinical trials.

Further, our research or product development efforts may not be successfully completed, any compounds we currently have under development may not be successfully developed into drugs, may not receive regulatory approval on a timely basis, if at all, and competitors may develop and bring to market products or technologies that render our potential products obsolete. If any of these events occur, our business would be materially and adversely affected.

If clinical trials or regulatory approval processes for our product candidates are prolonged, delayed or suspended, we may be unable to commercialize our product candidates on a timely basis, which would require us to incur additional costs and delay our receipt of any revenue from potential product sales.

We cannot predict whether we, or our strategic partners if our product candidates are licensed, will encounter problems with any of our completed, ongoing or planned clinical trials that will cause us or any regulatory authority to delay or suspend those clinical trials or delay the analysis of data derived from them. ASeveral ~~number of~~ events, including any of the following, could delay the completion of our ongoing and planned clinical trials and negatively impact ~~our~~ our ability to obtain regulatory approval for, and to market and sell, a particular product candidate:

●

conditions imposed on us by the FDA or another foreign regulatory authority regarding the scope or design of our clinical trials;

●

delays in obtaining, or our inability to obtain, required approvals from institutional review boards or other reviewing entities at clinical sites selected for participation in our clinical trials;

●

insufficient supply of our product candidates or other materials necessary to conduct and complete our clinical trials;

●

slow enrollment and retention rate of subjects in our clinical trials;

●

serious and unexpected drug-related side effects related to the product candidate being tested; and

●

delays in meeting manufacturing and testing standards required for production of clinical trial supplies.

Commercialization of our product candidates may be delayed by the imposition of additional conditions on our clinical trials by the FDA or any other applicable foreign regulatory authority or the requirement of additional supportive studies by the FDA or such foreign regulatory authority. In addition, clinical trials require sufficient patient enrollment, which is a function of many factors, including the size of the patient population, the nature of the trial protocol, the proximity of patients to clinical sites, the availability of effective treatments for the relevant disease, the conduct of other clinical trials that compete for the same patients as our clinical trials, and the eligibility criteria for our clinical trials. Our failure to enroll patients in our clinical trials could delay the completion of the clinical trial beyond its expectations. In addition, the FDA could require us to conduct clinical trials with a larger number of subjects than we may have projected for any of our product candidates. We may not be able to enroll a sufficient number of patients in a timely or cost-effective manner. Furthermore, enrolled patients may drop out of our clinical trials, which could impair the validity or statistical significance of the clinical trials.

We do not know whether our clinical trials will begin as planned, will need to be restructured, or will be completed on schedule, if at all. Delays in our clinical trials will result in increased development costs for our product candidates, and our financial resources may be insufficient to fund any incremental costs. In addition, if our clinical trials are delayed, our competitors may be able to bring products to market before we do and the commercial viability of our product candidates could be limited. In cases where an outside party, such as the NCI conducts a clinical trial on our behalf, we may not have direct involvement in discussions with the FDA regarding the factors discussed above.-8-

Even if we receive regulatory approval to market a product candidate, the manufacturing, labeling, packaging, adverse event reporting, storage, advertising, promotion, and record keeping related to the product will remain subject to extensive regulatory requirements. If we fail to comply with the regulatory requirements of the FDA and other applicable domestic and foreign regulatory authorities or discover any previously unknown problems with any approved product, manufacturer, or manufacturing process, we could be subject to administrative or judicially imposed sanctions, including:

●

restrictions on the products, manufacturers, or manufacturing processes;

●

warning letters;

●

civil or criminal penalties;

●

fines;

●

injunctions;

●

product seizures or detentions;

●

pressure to initiate voluntary product recalls;

●

suspension or withdrawal of regulatory approvals; and

●

refusal to approve pending applications for marketing approval of new products or supplements to approved applications.

Our industry is highly competitive, and our product candidates may become obsolete.

We are engaged in a rapidly evolving field. Competition from other pharmaceutical companies, biotechnology companies and research and academic institutions is intense and likely to increase. Many of those companies and institutions have substantially greater financial, technical and human resources than we do. Those companies and institutions also have substantially greater experience in developing products, conducting clinical trials, obtaining regulatory approval and in manufacturing and marketing pharmaceutical products. Our competitors may succeed in obtaining regulatory approval for their products more rapidly than we do. Competitors have developed or are in the process of developing technologies that are, or in the future may be, the basis for competitive products. We are aware of potential competitors developing products similar to our sarcoma vaccine, ovarian cancer vaccine and pancreatic cancer antibodies product candidates. Our competitors may succeed in developing products that are more effective and/or cost competitive than those we are developing, or that would render our product candidates less competitive or even obsolete. In addition, one or more of our competitors may achieve product commercialization or patent protection earlier than we do, which could materially adversely affect our business.

If physicians and patients do not accept our future products, or our potential strategic partner’s products, or if the market for indications for which any product candidate is approved is smaller than expected, we may be unable to generate significant revenue, if any.

Even if any of our product candidates obtain regulatory approval, they may not gain market acceptance among physicians, patients, and third-party payers. Physicians may decide not to recommend our treatments for a variety of reasons including:

●

timing of market introduction of competitive products;

●

demonstration of clinical safety and efficacy compared to other products;

●

cost-effectiveness;

●

limited or no coverage by third-party payers;

●

convenience and ease of administration;

●

prevalence and severity of adverse side effects;

●

restrictions in the label of the drug;

●

other potential advantages of alternative treatment methods; and

●

ineffective marketing and distribution support of its products.

If any of our product candidates are approved, but fail to achieve market acceptance or such market is smaller than anticipated, we may not be able to generate significant revenue and our business would suffer.

As we evolve from a company that is primarily involved in clinical development to a company that is also involved in licensing and commercialization, we may encounter difficulties in expanding our operations successfully.

As we or our potential strategic partners advance our product candidates through clinical trials, we ~~may~~will need to expand our development, regulatory, manufacturing, marketing and sales capabilities and may need to further contract with third parties to provide these capabilities. As our operations expand, we likely will need to manage additional relationships with such third parties, as well as additional collaborators, distributors, marketers and suppliers.

Maintaining third party relationships for these purposes will impose significant added responsibilities on members of our management and other personnel. We must be able to: manage our development efforts effectively; recruit and train sales and marketing personnel; manage our participation in the clinical trials in which our product candidates are involved effectively; and improve our managerial, development, operational and finance systems, all of which may impose a strain on our administrative and operational infrastructure.

If we enter into arrangements with third parties to perform sales, marketing or distribution services, any product revenues that we receive, or the profitability of these product revenues to us, ~~our revenues~~ are likely to be lower than if we were to market and sell any products that we develop without the involvement of these third parties. In addition, we may not be successful in entering into ~~arrangements~~ arrangements with third parties to license, sell and market our products or in doing so on terms that are favorable to us. We likely will have little control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our products effectively. 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~~ commercializing our products.

The uncertainty associated with pharmaceutical reimbursement and related matters may adversely affect our business.

Market acceptance and sales of any one or more of our product candidates will depend on reimbursement policies and may be affected by future healthcare reform measures in the United States and in foreign jurisdictions. Government authorities and third-party payers, such as private health insurers and health maintenance organizations, decide which drugs they will cover and establish payment levels. We cannot be certain that reimbursement will be available for any of our product candidates. Also, we cannot be certain that reimbursement policies will not reduce the demand for, or the price paid for, our products. If reimbursement is not available or is available on a limited basis, we may not be able to successfully commercialize any product candidates that we develop.

In the United States, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, also called the Medicare Modernization Act, or MMA, changed the way Medicare covers and pays for pharmaceutical products. The legislation established Medicare Part D, which expanded Medicare coverage for outpatient prescription drug purchases by the elderly but provided authority for limiting the number of drugs that will be covered in any therapeutic class. The MMA also introduced a new reimbursement methodology based on average sales prices for physician-administered drugs.

The United States and several foreign jurisdictions are considering, or have already enacted, a number of legislative and regulatory proposals to change the healthcare system in ways that could affect our ability to sell our products profitably. Among policy makers and payers in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access to healthcare. In the United States, the pharmaceutical industry ~~has~~is ~~been a particular focus of these efforts and has been~~ significantly affected by major ~~legislative~~ legislative initiatives. We expect to experience pricing pressures in in connection with the sale of any products that it develops due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative proposals.

Moreover, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act, or collectively, ACA, is intended to reduce the cost of health care and substantially change the way health care is financed by both government and private insurers. While we cannot predict what impact on federal reimbursement policies this legislation will have in general or on our business specifically, the ACA may result in downward pressure on pharmaceutical reimbursement, which could negatively affect market acceptance of, and the price we charge for, any products we develop that receive regulatory approval.

Our ability to generate product and/or licensing revenues will be diminished if our therapies sell for inadequate prices or patients are unable to obtain adequate levels of reimbursement.

Our ability or our potential strategic partners’ abilities to commercialize our therapies, alone or with collaborators, will depend in part on the extent to which reimbursement will be available from private health maintenance organizations and health insurers and other healthcare payers. Significant uncertainty exists as to the reimbursement status of newly approved healthcare products. Healthcare payers are challenging the prices charged for medical products and services. Cost control initiatives could decrease the price that we would receive for any products in the future, which would limit our revenue and profitability. Government and other healthcare payers increasingly attempt to contain healthcare costs by limiting both coverage and the level of reimbursement for drugs and therapeutics. We might need to conduct post-marketing studies in order to demonstrate the cost-effectiveness of any future products to such payers’ satisfaction. Such studies might require us to commit a significant amount of management time and financial and other resources. Our future products might not ultimately be considered cost-effective. Even if one of our product candidates is approved by the FDA, insurance coverage may not be available, and reimbursement levels may be inadequate, to cover such therapies. If government and other healthcare payers do not provide adequate coverage and reimbursement levels for one of our products, once approved, market acceptance of such product could be reduced.

We only have a limited number of employees to manage and operate our business.

As of December 14, 2017, we have a total of 11 full-time employees and one part-time employee. Our focus on limiting cash utilization requires us to manage and operate our business in a highly efficient manner. We cannot assure you that we will be able to retain adequate staffing levels to run our operations and/or to accomplish all of the objectives that we otherwise would seek to accomplish.

We depend heavily on our executive officers, directors, and principal consultants and the loss of their services would materially harm our business.

We believe that our success depends, and will likely continue to depend, upon our ability to retain the services of our current executive officers, directors, principal consultants and others. In addition, we have established relationships with universities, hospitals and research institutions, which have historically provided, and continue to provide, us with access to research laboratories, clinical trials, facilities and patients. The loss of the services of any of these individuals or institutions would have a material adverse effect on our business.

Our internal computer systems, or those of our third-party service providers, licensees, licensors, collaborators or other contractors or consultants, may fail or suffer security breaches, which could result in a material disruption in our business and operations.

Despite the implementation of security measures, our internal computer systems and those of our current and future service providers, licensees, licensors, collaborators and other contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. While we are not aware of any such material system failure, accident or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our development programs and our business operations. For example, the loss of clinical trial data from completed, on-going or future clinical trials could result in delays in our regulatory approval efforts and significant costs to recover or reproduce the data. Likewise, we rely on third parties to manufacture our drug candidates and conduct clinical trials, and similar events relating to their computer systems could also have a material adverse effect on our business. 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 liabilities and the further development and commercialization of our product candidates could be delayed.

Due in part to our limited financial resources, we may fail to select or capitalize on the most scientifically, clinically or commercially promising or profitable indications or therapeutic areas for our product candidates or those that are in-licensed, and/or we may be unable to pursue the clinical trials that we would like to pursue.

We have limited technical, managerial and financial resources to determine the indications on which we should focus the development efforts related to our product candidates. Due to our limited available financial resources, we may have curtailed clinical development programs and activities that might otherwise have led to more rapid progress of our product candidates through the regulatory and development processes.

We may make incorrect determinations with regard to the indications and clinical trials on which to focus the available resources that we do have. Furthermore, we cannot assure you that we will be able to retain adequate staffing levels to run our operations and/or to accomplish all of the objectives that we otherwise would seek to accomplish. Our decisions to allocate our research, management and financial resources toward particular indications or therapeutic areas for our product candidates may not lead to the development of viable commercial products and may divert resources from better opportunities. Similarly, our decisions to delay or terminate drug development programs may also cause us to miss valuable opportunities.

If the third parties on which we rely for the conduct of our clinical trials and results do not perform our clinical trial activities in accordance with good clinical practices and related regulatory requirements, we may be unable to obtain regulatory approval for or commercialize our product candidates.

We use independent clinical investigators and other third-party service providers to conduct and/or oversee the clinical trials of our product candidates and expect to continue to do so for the foreseeable future. We rely heavily on these parties for successful execution of our clinical trials. Nonetheless, we are responsible for confirming that each of our clinical trials is conducted in accordance with the FDA’s requirements and our general investigational plan and protocol.

-16-

Table of Contents

The FDA requires us and our clinical investigators to comply with regulations and standards, commonly referred to as good clinical practices, for conducting and recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the trial participants are adequately protected. Our reliance on third parties that we do not control does not relieve us of these responsibilities and requirements. Third parties may not complete activities on schedule or may not conduct our clinical trials in accordance with regulatory requirements or the respective trial plans and protocols. The failure of these third parties to carry out their obligations could delay or prevent the development, approval and commercialization of our product candidates or result in enforcement action against us.

We have limited manufacturing capacity and have relied on, and expect to continue to rely on, third-party manufacturers to produce our product candidates.

We do not own or operate manufacturing facilities for the production of clinical or commercial quantities of our product candidates, and we lack the resources and the capabilities to do so. As a result, we currently rely, and expect to rely for the foreseeable future, on third-party manufacturers to supply our product candidates. Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured our product candidates or products ourselves, including:

●

reliance on third-parties for manufacturing process development, regulatory compliance and quality assurance;

●

limitations on supply availability resulting from capacity and scheduling constraints of third-parties;

●

the possible breach of manufacturing agreements by third-parties because of factors beyond our control; and

●

the possible termination or non-renewal of the manufacturing agreements by the third-party, at a time that is costly or inconvenient to us.

If we do not maintain our key manufacturing relationships, we may fail to find replacement manufacturers or develop our own manufacturing capabilities, which could delay or impair our ability to obtain regulatory approval for our products and substantially increases our costs or deplete profit margins, if any. If we do find replacement manufacturers, we may not be able to enter into agreements with them on terms and conditions favorable to us and there could be a substantial delay before new facilities could be qualified and registered with the FDA and other foreign regulatory authorities.

Table of Contents

The FDA and other foreign regulatory authorities require manufacturers to register manufacturing facilities. The FDA and corresponding foreign regulators also inspect these facilities to confirm compliance with current cGMPs. Contract manufacturers may face manufacturing or quality control problems causing drug substance production and shipment delays or a situation where the contractor may not be able to maintain compliance with the applicable cGMP requirements. Any failure to comply with cGMP requirements or other FDA, EMA and comparable foreign regulatory requirements could adversely affect our clinical research activities and our ability to develop our product candidates and market our products following approval.

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

If product liability lawsuits are successfully brought against us, we may incur substantial liabilities and may be required to limit commercialization of our product candidates and any products that we may develop.

-17-

Table of Contents

The testing and marketing of medical products entail an inherent risk of product liability. Although we are not aware of any historical or anticipated product liability claims or specific causes for concern, if we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our product candidates and any products that we may develop. In addition, product liability claims may also result in withdrawal of clinical trial volunteers, injury to our reputation and decreased demand for any products that we may commercialize. We currently carry product liability insurance that covers our clinical trials up to a $5.0 million annual aggregate limit. We will need to increase the amount of coverage if and when we have a product that is commercially available. If we are unable to obtain sufficient product liability insurance at an acceptable cost, potential product liability claims could prevent or inhibit the commercialization of any products that we may develop, alone or with corporate partners.

We have been, and in the future may be, subject to securities class action lawsuits and stockholder derivative actions. These, and potential similar or related litigation, could result in substantial damages and may divert management’s time and attention from our business.

We have been, and may in the future be, the target of securities class actions or stockholder derivative claims. Any such actions or claims could result in substantial damages and may divert management’s time and attention from our business.

Risks Related to our Intellectual Property

It is difficult and costly to protect our proprietary rights, and we may not be able to ensure their protection.

We have been issued patents, applied for other patents, and intend on continuing to seek additional patent protection for our families of antibodies from our antibody development program, our vaccines, methods of use and other compounds that we discover. However, any or all of such compounds, methods or new uses of known compounds may not be subject to effective patent protection. Further, the development of regimens for the administration of our vaccines, which involve specifications for the frequency, timing and amount of dosages, has been, and we believe may continue to be, important to our efforts, although those processes, as such, may not be patentable. In addition, our issued patents may be declared invalid or our competitors may find ways to avoid the claims in the patents.

Our commercial success will depend, in part, on our ability to obtain and maintain patent protection, protect our trade secrets and operate without infringing on the proprietary rights of others. Our commercial success will also depend, in part, on our ability to market our product candidates during the term of our patent protection. For example, certain patents including in foreign countries within our portfolio expired in 2014 and can no longer be relied on for protection in those countries. As of ~~December~~November 1419, ~~2017~~2018, we were the exclusive licensee or sole assignee of 14 granted United States patents, 34 pending United States patent applications, ~~7 international patents~~ and 19 pending ~~international patent~~foreign patent applications. The patent position of pharmaceutical and biotechnology firms like us are generally highly uncertain and involves complex legal and factual questions, resulting in both an apparent inconsistency regarding the breadth of claims allowed in United States patents and general uncertainty as to their legal interpretation and enforceability. No absolute policy regarding the breadth of claims allowed in ~~biopharmaceutical~~ biopharmaceutical patents has emerged to date in the United States or in many foreign jurisdictions. Changes in either the patent laws or in interpretations of patent laws in the United States and ~~foreign~~ foreign jurisdictions may diminish the value of our intellectual property. Accordingly, we cannot predict the breadth of claims that may be enforced in the patents that we currently own or that may be ~~issued~~ issued from the applications we have filed or may file in the future or that we have licensed or may license from third parties, ~~including~~ including MSK for the vaccine antigen patents. Further, if any patents we obtain or license are deemed invalid or unenforceable, it could impact our ability to commercialize or license our technology. Thus, patent applications assigned or exclusively licensed to us may not result in patents being issued, any issued patents assigned or exclusively licensed to us may not provide us with competitive protection or may be challenged by others, and the current or future granted patents of others may have an adverse effect on our ability to do business and achieve profitability.

One of our issued US patents is directed to a candidate antibody product that will expire in 2034. Other previously filed antibody patent applications will, if issued, have patent expiration dates depending on country and filing date between 2034 and 2038. It is possible that the term of the antibody patent and certain patents issuing from the antibody patent applications may be extended for a portion of the time the candidate product was under regulatory review. Patents covering components of the sarcoma vaccine will expire in 2022. Patents covering the polyvalent ovarian vaccine will expire between 2018 and 2025. We believe that our product candidates are eligible for Orphan Drug designation from FDA depending on the indication for which it is approved by FDA. Each product that receives an Orphan Drug designation would be eligible for up to 7 additional years of patent protection.-13-

One of our issued US patents is directed to a candidate antibody product that will expire in 2034. A second US patent directed to a candidate antibody will expire in 2035. Other previously filed antibody patent applications will, if issued, have patent expiration dates depending on country and filing date between 2034 and 2038. It is possible that the term of the antibody patent and certain patents issuing from the antibody patent applications may be extended for a portion of the time the candidate product was under regulatory review. Patents covering components of the sarcoma vaccine will expire in 2022. Patents covering the polyvalent ovarian vaccine will expire between 2019 and 2025. We believe that our product candidates are eligible for Orphan Drug designation from FDA depending on the indication for which it is approved by FDA. Each product that receives an Orphan Drug designation would be eligible for up to 7 additional years of patent protection.

The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:

●

others may be able to make compounds that are similar to our vaccines and monoclonal antibody-based candidates and any future product candidates we may seek to develop but that are not covered by the claims of our patents;

●

if we encounter delays in our clinical trials, the period ~~of time~~ during which we could market our vaccines and monoclonal antibody-based candidates under patent protection would be reduced;

●

we might not have been the first to conceive, make or disclose the inventions covered by our patents or pending patent applications;

●

we might not have been the first to file patent applications for these inventions;

●

any patents that we obtain may be invalid or unenforceable or otherwise may not provide us with any competitive advantages; or

●

the patents of others may have a material adverse effect on our business.

Due to the patent laws of a country, or the decisions of a patent examiner in a country, or our own filing strategies, we may not obtain patent coverage for all the product candidates that may be disclosed or methods involving these candidates that may be disclosed in the parent patent application. We plan to pursue divisional patent applications and/or continuation patent applications in the United States and many other countries to obtain claim coverage for inventions that were disclosed but not claimed in the parent patent application, but may not succeed in these efforts.

Composition of matter patents on the active biological component are generally considered to be the strongest form of intellectual property protection for biopharmaceutical products, as such patents generally provide protection without regard to any method of use. We cannot be certain that the claims in our patent applications covering composition-of-matter of our candidates will be considered patentable by the U.S. Patent and Trademark Office, or USPTO, courts in the United States or by the patent offices and courts in foreign countries. Method of use patents protect the use of a product for the method recited in the claims. This type of patent does not prevent a competitor from making and marketing a product that is identical to our product for an indication that is outside the scope of the patented method. Moreover, even if competitors do not actively promote their product for our targeted indications, physicians may prescribe these products “off-label.” Although off-label prescriptions may infringe or contribute to or induce the infringement of method of use patents, the practice is common and such infringement is difficult to prevent or prosecute. Interference proceedings provoked by third parties or brought by the USPTO may be necessary to determine the priority of inventions with respect to our patents or patent applications or those of our collaborators or licensors. An unfavorable outcome could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Litigation or interference proceedings may fail, resulting in harm to our business, and, even if successful, may result in substantial costs and distract our management and other employees.

There have been numerous changes to the patent laws and proposed changes to the rules of the USPTO, which may have a significant impact on our ability to protect our technology and enforce our intellectual property rights. For example, the America Invents Act signed into law in September 2011 that codifies several significant changes to the U.S. patent laws, including, among other things, changing from a “first to invent” to a “first inventor to file” system, limiting where a patent holder may file a patent suit, replacing interference or “first to invent” proceedings with derivation proceedings and creating inter partes review and post-~~19-~~grant opposition proceedings to challenge the validity of patents after they have been issued. The effects of these changes are currently unclear as the USPTO only recently has adopted regulations implementing the changes, the courts have yet to address most of these provisions, and the applicability of the act and new regulations on specific patents and patent applications discussed herein have not been determined and would need to be reviewed.

In addition, we could incur substantial costs in defending suits brought against us~~ or ~~about patents to~~ ~~which~~disclosure weof ~~hold~~such ~~licenses or in suing to protect our own patents against infringement~~information.

We require employees and the institutions that perform our preclinical and clinical trials to enter confidentiality agreements with us. Those agreements provide that all confidential information developed or made known to a party to any such agreement during the relationship with us be kept confidential and not be disclosed to third-parties, except in specific circumstances. Any such agreement may not provide meaningful protection for our trade secrets or other confidential information in the event of unauthorized use or disclosure of such information.

With respect to our vaccine programs we have in-licensed rights from third parties. If these license agreements terminate or expire, we may lose the licensed rights to some or all our vaccine product candidates. We may not be able to continue to develop them or, if they are approved, market or commercialize them.

We depend on license agreements with third-20parties for certain intellectual property rights relating to our product candidates, including, but not limited to, the license of certain intellectual property rights from MSK. In general, our license agreements require us to make payments and satisfy performance obligations to keep these agreements in effect and retain our rights under them. These payment obligations can include upfront fees, maintenance fees, milestones, royalties, patent prosecution expenses, and other fees. These performance obligations typically include diligence obligations. If we fail to pay, be diligent or otherwise perform as required under our license agreements, we could lose the rights under the patents and other intellectual property rights covered by these agreements. If disputes arise under any of our in-licenses, including our in-licenses from MSK, we could lose our rights under these agreements. Any such dispute may not be resolvable on favorable terms, or at all. Whether or not any disputes of this kind are favorably resolved, our management’s time and attention and our other resources could be consumed by the need to attend to these disputes and our business could be harmed by the emergence of such a dispute.

If we lose our rights under these agreements, we might not be able to develop any related product candidates further, or following regulatory approval, if any, we might be prohibited from marketing or commercializing these product candidates. For example, patents previously licensed to us might, after termination of an agreement, be used to stop us from conducting these activities.

Whether any disputes of this kind are favorably resolved, our management’s time and attention and our other resources could be consumed by the need to attend to these disputes and our business could be harmed by the emergence of such a dispute.

If we lose our rights under these agreements, we might not be able to develop any related product candidates further, or following regulatory approval, if any, we might be prohibited from marketing or commercializing these product candidates. In particular, patents previously licensed to us might, after termination of an agreement, be used to stop us from conducting these activities.

We are dependent on MSK for the establishment of our intellectual property rights related to the vaccine program, and if MSK has not established our intellectual property rights with sufficient scope to protect our vaccine candidates, we may have limited or no ability to assert intellectual property rights to our vaccine candidates.

Under our agreement with MSK, MSK was responsible for establishing the intellectual property rights to the vaccine antigen conjugates, mixtures of vaccine antigen conjugates that make up polyvalent vaccine candidates and methods of use. As we were not responsible for the establishment of our intellectual property rights to these vaccine antigen conjugates, mixtures of vaccine antigen conjugates and methods of use, we have less visibility into the strength of our intellectual property rights to our vaccine candidates than if we had been responsible for the establishment of these rights. If MSK did not establish those rights so they are of sufficient scope to protect the vaccine candidates, then we may not be able to prevent others from using or commercializing some or all of our vaccine candidates, and others may be able to assert intellectual property rights in our vaccine candidates and prevent us from further pursuing the development and commercialization of our vaccine candidates.

We may not obtain exclusive rights to intellectual property created ~~because~~as a result of our strategic collaborative agreements.

We are party to collaborative research agreements, such as with Rockefeller University and MSK, and expect to enter into agreements with other parties in the future, each of which involve research and development efforts. Under certain circumstances, we may not have exclusive rights to jointly developed intellectual property and would have to license the collaborative partner’s interest in the jointly developed intellectual property to obtain exclusive rights. We may not be able to to license our collaborative partner’s interest or license ~~their~~ their interest at reasonable terms. If we are unable to license their interest we would not have exclusive rights to the jointly developed intellectual property and, in some collaborations, the collaborative partner may be free to license their interest in the jointly developed intellectual property to a competitor. In other collaborations, if we are unable to license the collaborative partner’s interest we may not have sufficient rights to practice the jointly developed intellectual property. Such provisions to the jointly developed intellectual property may limit our ability to gain commercial benefit from some of or all of the intellectual property we jointly develop with our collaborative partners and may lead to costly or time-consuming disputes with parties with whom we have collaborative relationships over rights to certain innovations or with other third parties that may result from the activities of the collaborative arrangements.

We may incur substantial costs ~~because~~as a result of litigation or other proceedings relating to patent and other intellectual property rights and we may be unable to enforce or protect our rights to, or use, our technology.

If we choose to go to court to stop another party from using the inventions claimed in any patents we obtain, that individual or company has the right to ask the court to rule that such patents are invalid or should not be enforced. These lawsuits are expensive and would consume time and resources and divert the attention of managerial and scientific personnel even if we were successful in stopping the infringement of such patents or sustaining their validity and enforceability. In addition, there is a risk that the court will decide that such patents are not valid and that we do not have the right to enforce them. There is also the risk that, even if the validity of such patents is upheld, the court will refuse to stop the other party on the grounds that such other party’s activities do not infringe such patents. In addition, the United States Court of Appeals for the Federal Circuit and the Supreme Court of the ~~United~~U.S. ~~States~~ continue to address issues under ~~the~~ the United States patent laws, and the decisions of those and other courts could adversely affect our ability to sustain the validity of our issued or licensed patents and obtain new patents.

Furthermore, a third party may claim that we or our manufacturing or commercialization partners or customers are using inventions covered by the third party’s patent rights and may go to court to stop us or our partners and/or customers from engaging in our operations and activities, including making or selling our vaccine and monoclonal antibody-based candidates and any future product candidates we may seek to develop. These lawsuits are costly and could affect our results of operations and divert the attention of managerial and scientific personnel. There is a risk that a court would decide that we or our commercialization partners or customers are infringing the third party’s patents and would order us or our partners or customers to stop the activities covered by the patents. In that event, we or our commercialization partners or customers may not have a viable way around the patent and may need to halt commercialization or use of the relevant product. In addition, there is a risk that a court will order us or our partners or customers to pay the other party damages for having violated the other party’s patents or obtain one or more licenses from third parties, which may be impossible or require substantial time and expense. We cannot predict whether any license would be available at all or whether it would be available on commercially reasonable terms. Furthermore, even in the absence of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization of our candidates, and we have done so from time to time. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In such events, we would be unable to further develop and commercialize one or more of our drug candidates, which could harm our business significantly. In the future, we may agree to indemnify our commercial partners and/or customers against certain intellectual property infringement claims brought by third parties which could increase our financial expense, increase our involvement in litigation and/or otherwise materially adversely affect our business.

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, which could adversely affect our intellectual property rights and our business. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments. 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.

The pharmaceutical and biotechnology industries have produced a proliferation of patents, and it is not always clear to industry participants, including us, which patents cover various types of products or methods of use. The coverage of patents is subject to interpretation by the courts, and the interpretation is not always uniform. If we are sued for patent infringement, we would need to demonstrate that our products or methods either do not infringe the patent claims of the relevant patent or that the patent claims are invalid or unenforceable, and we may not be able to do this. Proving invalidity or unenforceability is difficult. For example, in the United States, proving invalidity requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents.

Because some patent applications in the United States may be maintained in secrecy until the patents are issued, because patent applications in the United States and many foreign jurisdictions are typically not published until eighteen months after filing, because searches and examinations of patent applications by the USPTO and other patent offices may not be comprehensive, and because publications in the scientific literature often lag behind actual discoveries, we cannot be certain that others have not filed patent applications for technology covered by our patents or pending applications. Our competitors may have filed, and may in the future file, patent applications and may have obtained patents covering technology similar to ours. Any such patents or patent application may have priority over our patent applications, which could further require us to obtain or license rights to issued patents covering such technologies. If another party has obtained a U.S. patent or filed a U.S. patent application on inventions similar to ours, we may have to participate in a proceeding before the USPTO or in the courts to determine which patent or application has priority. The costs of these proceedings could be substantial, and it is possible that our application or patent could be determined not to have priority, which could adversely affect our intellectual property rights and business.

We have received confidential and proprietary information from collaborators, prospective licensees and other third parties. In addition, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies. We may be subject to claims that we or our employees, consultants or independent contractors have improperly used or disclosed confidential information of these third parties or our employees’ former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial cost and be a distraction to our management and employees. If we are not successful, our ability to continue our operations and our business could be materially, adversely affected.

Some of our competitors may be able to sustain the costs of complex intellectual property litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations, on our ability to hire or retain employees, or otherwise on our business.

~~Risks~~Our ~~Related~~restated certificate of incorporation, our amended and restated by-laws and Delaware law could deter a change of our management which could discourage, or delay, offers to acquire us; certain restrictions in our ~~Common~~agreements ~~Stock~~with existing stockholders could also discourage or delay offers to acquire us.

Our restated certificate of incorporation, our amended and restated by-laws and Delaware law could deter a change of our management which could discourage or delay offers to acquire us; certain restrictions in our agreements with existing stockholders could also discourage or delay offers to acquire us.

Certain provisions of Delaware law and of our restated certificate of incorporation, as amended, and amended and restated by-laws, could discourage or make it more difficult to accomplish a proxy contest or other change in our management or the acquisition of control by a holder of a substantial amount of our voting stock. It is possible that these provisions could make it more difficult to accomplish, or could deter, transactions that stockholders may otherwise consider to be in their best interests or in our best interests. These provisions include:

●

establishing a classified board of directors requiring that members of the board be elected in different years, which lengthens the time needed to elect a new majority of the board;

●

authorizing the issuance of “blank check” preferred stock that could be issued by our ~~board~~Board of ~~directors~~Directors to increase the number of outstanding shares or change the balance of voting control and thwart a takeover attempt;

●

prohibiting cumulative voting in the election of directors, which would otherwise allow for less than a majority of stockholders to elect director candidates;

●

limiting the ability of stockholders to call special meetings of the stockholders;

●

prohibiting stockholder action by written consent and requiring all stockholder actions to be taken at a meeting of our stockholders; and

●

establishing 90 to 120-day advance notice requirements for nominations for election to the board of directors and for proposing matters that can be acted upon by stockholders at stockholder meetings.

We may ~~fail~~not be able to ~~regain~~achieve compliance for ~~continued~~ listing on ~~the NASDAQ Capital Market and~~ a ~~delisting~~national exchange ofwhich ~~our stock~~ could make it more difficult for investors to sell their shares.

Our common stock was ~~approved~~delisted ~~for~~on ~~listing~~The Nasdaq Capital Market on July 11, 2018 and currently trades on the ~~NASDAQ~~OTC ~~Capital~~Pink ~~Market~~market. Delisting of our common stock effectively results in ~~August~~our ~~2016~~common ~~where~~stock being designated a “penny stock” is that securities broker-dealers cannot recommend the shares but must trade it ~~continues~~on toan beunsolicited ~~listed~~basis. Penny ~~The~~stock ~~listing~~rules require a broker-dealer, prior to a transaction in a penny stock not otherwise exempt from those rules, to deliver a standardized risk disclosure document prepared by the SEC, which specifies information about penny stocks and the nature and significance of risks of the ~~NASDAQ~~penny ~~Capital~~stock ~~Market~~market. A broker-dealer must also provide the customer with bid and offer quotations for the penny stock, the compensation of the broker-dealer and sales person in the transaction, and monthly account statements indicating the market value of each penny stock held in the customer’s account. In addition, the penny stock rules require that, prior to a transaction in a penny stock not otherwise exempt from those rules; the ~~Company~~broker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser’s written agreement to ~~meet~~the ~~certain~~transaction. ~~requirements~~Additionally, subsequent transfers of the shares of our common stock by U.S. holders may not be exempt from state securities laws. In such event, it will be the responsibility of the holder of shares or warrants to register or qualify the shares for any subsequent offer, transfer or sale in the United States or to determine that any such offer, transfer or sale is exempt under applicable state securities laws. These ~~continued~~state ~~listing~~securities laws ~~standards~~and disclosure requirements may have the effect of reducing ~~include~~the ~~specifically~~trading ~~enumerated~~activity ~~criteria~~in the secondary market for shares that become subject to those penny stock rules. Under such circumstances, shareholders may find it more difficult to sell, or to obtain accurate quotations, for our common stock, and our common stock would become substantially less attractive to certain purchasers such as: financial institutions, hedge funds and other similar investors.

compliance with theNASDAQ Capital Market’s corporate governance requirements, as well as additional or more stringent criteria that may be applied in the exercise of theNASDAQ Capital Market’s discretionary authority.

On September 6, 2017, the NASDAQ Capital Market informed the Company that it had failed to maintain a minimum bid price of $1.00 per share for more than 30 consecutive business days. The Company can regain compliance if, at any time during the 180-day period ending March 5, 2018, the closing bid price of the common stock is at least $1.00 for a minimum of ten consecutive business days. On October 2, 2017, at a special meeting of stockholders, our Board of Directors received approval, if the Board deems to be necessary to achieve a higher stock price to continue to meet the continued listing qualifications for the NASDAQ Capital Market, to amend our Amended and Restated Certificate of Incorporation to effect a reverse stock split of our issued and outstanding common stock by a ratio of not less than one-for-two and not more than one-for-twenty at any time prior to September 28, 2018, with the exact ratio to be set at a whole number within this range as determined by the Board of Directors in its sole direction to continue to meet the continued listing qualifications for the NASDAQ Capital Market. No decision has been made yet by our Board of Directors to implement a reverse split. However, if we were to effect such a reverse stock split, our stockholders may bring actions against us in connection with that reverse stock split that could divert management resources, cause us to incur significant expenses or cause our common stock to be further diluted. Continued listing during this period is also contingent on our continued compliance with all listing requirements other than for the minimum bid price. On August 22, 2017, the NASDAQ Capital Market notified us that we also no longer satisfied the minimum $2.5 million stockholders’ equity requirement as of June 30, 2017. As of September 30, 2017, we regained compliance with the stockholders’ equity requirement.

Table of Contents

If we fail to comply with the NASDAQ Capital Market’s continued listing standards, we may be delisted and our common stock will trade, if at all, only on the over-the-counter market, such as the OTC Bulletin Board or OTCQX market, and then only if one or more registered broker-dealer market makers comply with quotation requirements. In addition, delisting of our common stock could depress our stock price, substantially limit liquidity of our common stock and materially adversely affect our ability to raise capital on terms acceptable to us, or at all.

Finally, delisting of our common stock would likely result in our common stock becoming a “penny stock” under the Exchange Act. The principal result or effect of being designated a “penny stock” is that securities broker-dealers cannot recommend the shares but must trade it on an unsolicited basis. Penny stock rules require a broker-dealer, prior to a transaction in a penny stock not otherwise exempt from those rules, to deliver a standardized risk disclosure document prepared by the SEC, which specifies information about penny stocks and the nature and significance of risks of the penny stock market. A broker-dealer must also provide the customer with bid and offer quotations for the penny stock, the compensation of the broker-dealer and sales person in the transaction, and monthly account statements indicating the market value of each penny stock held in the customer’s account. In addition, the penny stock rules require that, prior to a transaction in a penny stock not otherwise exempt from those rules; the broker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser’s written agreement to the transaction. These disclosure requirements may have the effect of reducing the trading activity in the secondary market for shares that become subject to those penny stock rules. Under such circumstances, shareholders may find it more difficult to sell, or to obtain accurate quotations, for our common stock, and our common stock would become substantially less attractive to certain purchasers such as financial institutions, hedge funds and other similar investors.

Future sales of our securities, or the perception in the markets that these sales may occur, could depress our stock price.

Additional equity financings or other share issuances by us, including shares issued in connection with strategic alliances and corporate partnering transactions, could adversely affect the market price of our common stock. As of ~~December~~November 1419, ~~2017~~2018, we had 187,~~668~~869,~~610~~860 shares held by our existing shareholders available for resale pursuant to Rule 144 or resale registration statements, upon conversion of Series D Preferred Stock, Series E Preferred Stock, Series I Preferred Stock, Series J Preferred Stock, Series K Preferred Stock, ~~and~~ Series L Preferred Stock, Series M Preferred Stock, Series N Preferred Stock, and Series O Preferred Stock. Sales by existing stockholders of a large number of shares of our common stock in the public market or the perception that additional sales could occur could cause the market price of our common stock to drop. Moreover, to the extent ~~that~~ that additional shares of our outstanding stock are registered, or otherwise become eligible for resale, and are sold, or the holders of such shares are perceived as intended to sell them, this could further depress the market price of our common stock. These factors could also make it more difficult for us to raise capital or make acquisitions through the issuance of additional shares of our common stock or other equity securities.

If we do not progress in our programs as anticipated, our stock price could decrease.

For planning purposes, we estimate the timing of a variety of clinical, regulatory and other milestones, such as when a certain product candidate will enter clinical development, when a clinical trial will be completed or when an application for regulatory approval will be filed. Our estimates are based on present facts and a variety of assumptions. Many of the underlying assumptions are outside of our control. If milestones are not achieved when we estimated that they would be, investors could be disappointed, and our stock price may decrease.

Our stock price may be volatile; you may not be able to resell your shares at or above your purchase price.

Our stock prices and the market prices for securities of biotechnology companies in general have been highly volatile, with recent significant price and volume fluctuations, and may continue to be highly volatile in the future. For example, during the 12year ~~months~~ ended December 14 31, 2017, our common stock traded between $01.~~427~~28 per share and $410.2576 per share. The following factors, in addition to other risk factors described in this section, may have a significant impact on the market price of our common stock, some of which are beyond our control:

●

developments regarding, or the results of, our clinical trials;

●

announcements of technological innovations or new commercial products by our competitors or us;

●

our issuance of equity or debt securities, or disclosure or announcements relating thereto;

●

developments concerning proprietary rights, including patents;

●

developments concerning our collaborations;

-25-

Table of Contents

●

publicity regarding actual or potential medical results relating to products under development by our competitors or us;

●

regulatory developments in the United States and foreign countries;

●

litigation;

●

economic and other external factors or other disaster or crisis; or

●

period-to-period fluctuations in our financial results.

Our common stock may be affected by limited trading volume and price fluctuations which could adversely impact the value of our common stock.

While there has been relatively active trading in our common stock over the past twelve months, there can be no assurance that an active trading market in our common stock will be maintained. Our common stock has experienced, and is likely to experience in the future, significant price and volume fluctuations which could adversely affect the market price of our common stock without regard to our operating performance. In addition, we believe that factors such as quarterly fluctuations in our financial results and changes in the overall economy or the condition of the financial markets could cause the price of our common stock to fluctuate substantially. These fluctuations may also cause short sellers to periodically enter the market in the belief that we will have poor results in the future. We cannot predict the actions of market participants and, therefore, can offer no assurances that the market for our common stock will be stable or appreciate over time.

The number of shares of issued and outstanding common stock as of ~~December~~November 1419, ~~2017~~2018, represents approximately 4546% of our fully diluted shares of common stock. Additional issuances of shares of common stock upon conversion and/or exercise of preferred stock, options to purchase common stock and warrants to purchase ~~common~~ common stock will cause substantial dilution to existing stockholders.

At ~~December~~November 1419, ~~2017~~2018, we had 209,~~588~~254,~~765~~582 shares of common stock issued and outstanding. Up to an additional 187,~~668~~869,~~610~~860 shares may be ~~issued~~ issued upon conversion of our Series D Preferred Stock, Series E ~~Preferred~~ Preferred Stock, Series I Preferred Stock, Series J Preferred Stock, Series K Preferred Stock, ~~and~~ Series L Preferred Stock; Series M Preferred Stock; Series N Preferred Stock and Series O Preferred Stock A 1,~~268~~221,~~056~~935 shares issuable upon exercise of warrants at a weighted average price of $67.3715; 21,~~856~~820,~~092~~589 shares upon exercise of all outstanding options to purchase our common stock at a weighted average price of $47.6544; ~~and 2~~,~~496,671~~ ~~shares issuable upon vesting of restricted stock units granted,~~ resulting in a total of up to 45 20,~~878~~166,~~494~~ 966 shares that may be issued and outstanding. The issuance of any and all of the 259,~~289~~254,~~429~~582 shares issuable upon exercise or conversion of our outstanding convertible securities will cause ~~substantial~~ substantial dilution to existing stockholders and may depress the market price of our common stock.

If our common stock is not listed on a national securities exchange, compliance with applicable state securities laws may be required for subsequent offers, transfers and sales of the shares of common stock offered hereby.-19-

~~The~~Table securities offered hereby are being offered pursuant to one or more exemptions from registration and qualification under applicable state securities laws. Because our common stock is listed on the NASDAQ Capital Market, we are not required to register or qualify in any state the subsequent offer, transfer or sale of the common stock. If our common stock is delisted from the NASDAQ Capital Market and is not eligible to be listed on another national securities exchange, subsequent transfers of the shares of our common stock offered hereby by U.S. holders may not be exempt from state securities laws. In such event, it will be the responsibility of the holder of shares or warrants to register or qualify the shares for any subsequent offer, transfer or sale in the United States or to determine that any such offer, transfer or sale is exempt under applicable state securities laws.Contents

~~The~~You ~~rights~~will ofexperience ~~our~~future ~~common~~dilution ~~stockholders~~as are limited by and subordinate to the rights of the holders of Series D Preferred Stock, Series E Preferred Stock, Series I Preferred Stock, Series J Preferred Stock, Series K Preferred Stock and Series L Preferred Stock; these rights may have a ~~negative~~result ~~effect on the value~~ of ~~shares~~ offuture ~~our common stock~~equity offerings.

The holders of our Series D Preferred Stock, Series E Preferred Stock, Series I Preferred Stock, Series J Preferred Stock, Series K Preferred Stock and Series L Preferred Stock have rights and preferences generally superior to those of the holders of common stock. The existence of these superior rights and preferences may have a negative effect on the value of shares of our common stock. These rights are more fully set forth in the Series D Preferred Stock certificate of designations, Series E Preferred Stock certificate of designations, Series I Preferred Stock certificate of designations, Series J Preferred Stock certificate of designations, Series K Preferred Stock certificate of designations, and Series L Preferred Stock certificate of designations, respectively, and include, but are not limited to the right to receive a liquidation preference, prior to any distribution of our assets to the holders of our common stock, in an amount equal to $0.01 per share or $441 for the Series D Preferred Stock, $0.01 per share or $333 for the Series E Preferred Stock, $0.01 per share or $7,985 for the Series I Preferred Stock, $687.50 per share or approximately $531,252 for the Series J Preferred Stock, $0.01 per share or $632 for the Series K Preferred Stock and $100.00 per share or approximately $5.8 million for the Series L Preferred Stock.

You will experience future dilution as a result of future equity offerings

We may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock. Although no assurances can be given that we will consummate a financing, in the event we do, or in the event we sell shares of common stock or other securities convertible into shares of our common stock in the future, additional and substantial dilution will occur. In addition, investors purchasing shares or other securities in the future could have rights superior to investors in this offering.

~~-26-~~ Risks Related to the Offering with Triton

Resales of shares purchased by Triton under the Equity Purchase Agreement may cause the market price of our common stock to decline.

Subject to the terms and conditions of the Equity Purchase Agreement, we have the right to “put,” or sell, to Triton up to $1,000,000 worth of shares of our Series P Preferred Stock, which are convertible into shares of our common stock at a conversion rate of $100.00 divided by 75% of the 5-day volume-weighted average price of the Company’s common stock prior to the Series P Preferred Stock conversion notice. Unless terminated earlier, Triton’s purchase commitment will automatically terminate on the earlier of the date on which Triton shall have purchased shares pursuant to the Equity Purchase Agreement for an aggregate purchase price of $1,000,000 or 90 days after the effectiveness of a registration statement registering the resale of the shares of common stock underlying the Series P Preferred Stock purchased under the Equity Purchase Agreement. This arrangement is also sometimes referred to herein as the “Triton Offering.” The Series P Preferred Stock to be issued to Triton pursuant to the Equity Purchase Agreement will be purchased at a price equal to the stated value of $100.00 per share. Triton will have the financial incentive to sell the shares of our common stock issuable upon conversion of Series P Preferred Stock in advance of or upon receiving such shares and to realize the profit equal to the difference between the discounted price and the current market price of the shares. This may cause the market price of our common stock to decline. The foregoing description of the terms of the Equity Purchase Agreement does not purport to be complete and is subject to and qualified in its entirety by reference to the Equity Purchase Agreement itself.

Puts under Equity Purchase Agreement may cause dilution to existing stockholders.

From time to time during the term of the Equity Purchase Agreement, and at our sole discretion, we may present Triton with a put notice requiring Triton to purchase shares of our Series P Preferred Stock. As a result, our existing stockholders will experience immediate dilution upon the conversion into common stock of any of the shares of Series P Preferred Stock held by Triton. Triton may resell some, if not all, of the shares of our common stock issuable upon conversion of Series P Preferred Stock that we issue to it under the Equity Purchase Agreement and such sales could cause the market price of our common stock to decline significantly. To the extent of any such decline, any subsequent conversions of Series P Preferred Stock into common stock could require us to issue a greater number of shares to Triton in exchange for each dollar of the put amount depending on the timing of when Triton exercises its rights to conversions of Series P Preferred Stock. Under these circumstances, the existing stockholders of our company will experience greater dilution. The effect of this dilution may, in turn, cause the price of our common stock to decrease further, both because of the downward pressure on the stock price that would be caused by a large number of sales of our shares into the public market by Triton, and because our existing stockholders may dislike our decision to sell Series P Preferred Stock to Triton at a time when our stock price is low, and may in response decide to sell their own shares, further decreasing our stock price. If we draw down amounts under the Triton Offering when our share price is decreasing, we could be required to issue more shares to Triton upon subsequent conversions of Series P Preferred Stock.

There is no guarantee that we will satisfy the conditions to the Equity Purchase Agreement.

Although the Equity Purchase Agreement provides that we can require Triton to purchase, at our discretion, up to $1,000,000 worth of shares of our Series P Preferred Stock convertible into common stock, our ability to put shares to Triton and obtain funds when requested is limited by the terms and conditions of the Equity Purchase Agreement.

We may not have access to the full amount available under the Equity Purchase Agreement with Triton.

Our ability to draw down funds and sell shares under the Equity Purchase Agreement requires that a registration statement be declared effective and continue to be effective registering the resale of shares of our common stock issuable upon conversion of the Series P Preferred Stock purchased under the Equity Purchase Agreement. The registration statement of which this prospectus is a part registers the resale of up to 6,000,000 shares of our common stock issuable upon conversion of shares of our Series P Preferred Stock under the Triton Offering, and an additional 175,000 shares issued to Triton Fund LLC per the terms of the Share Donation Agreement. This registration statement (and any post-effective amendments thereto) may be subject to review and comment by the staff of the SEC and will require the consent of our independent registered public accounting firm. Therefore, the timing of effectiveness of the registration statement (and any post-effective amendments thereto) cannot be assured. Even if we are successful in causing the registration statement registering the resale of some or all of the shares issuable upon conversion of the Series P Preferred Stock under the Equity Purchase Agreement to be declared effective by the SEC in a timely manner, we may not be able to sell the shares unless certain other conditions are met. Accordingly, because our ability to draw down any amounts under the Equity Purchase Agreement with Triton is subject to a number of conditions, there is no guarantee that we will be able to draw down all of the proceeds of $1,000,000 under the Equity Purchase Agreement.

MANAGEMENT’S DISCUSSION AND ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of financial condition and results of operations should be read together with our financial statements and accompanying notes appearing elsewhere in this Prospectus. This Management’s Discussion and Analysis contains forward-looking statements that involve risks and uncertainties. Please see “Forward-Looking Statements” set forth in the beginning of this Prospectus, and see “Risk Factors” beginning on ~~page~~Page 5 9 for a discussion of certain ~~risk~~ risk factors applicable to our business, financial condition, and results of operations. Operating results are not necessarily indicative of results that may occur in future periods. Management and our independent registered public accounting firm identified certain material weaknesses in internal control over financial reporting. If we are unable to remediate these material weaknesses and maintain effective internal control, we may not be able to produce timely and accurate financial statements, and we and our independent registered public accounting firm could conclude that our internal control over financial reporting are not effective, which could adversely impact investor confidence and our stock price. See "“Risk Factors"” on ~~page~~Page 95.

Nasdaq De-listing and Application for Listing on the OTCQB Marketplace

On July 2, 2018, the Listing Qualifications Department of The Nasdaq Stock Market (the “Staff”) notified the Company of its determination to delist our securities. In this notice, the Staff indicated their determination was based upon the Company’s non-compliance with the Rule as well as the Company’s non-compliance with the $2.5 million stockholders’ equity requirement for continued listing on The Nasdaq Capital Market per Nasdaq listing rule 5550(b)(1). The Company elected not to appeal the Staff’s decision and, as a result, on July 2, 2018, we received a letter from the Staff indicating trading of the Company’s common stock would be suspended on The Nasdaq Capital Market at the open of business on Wednesday, July 11, 2018. On July 11, 2018, our common stock began trading on the OTC Pink, continuing under the symbol MBVX. On May 21, 2018, we notified the Staff that we would not be filing our Quarterly Report on Form 10-Q for the quarter ended March 31, 2018, by the required deadline as required for continued listing on The Nasdaq Capital Market per Nasdaq listing rule 5250(c)(1) (the “Rule”). Further, on June 29, 2018, the Company’s Board of Directors determined not to submit a plan to the Staff to regain compliance with the Rule, and we announced this decision in a press release on July 2, 2018. On September 26, 2018, The Nasdaq Stock Market announced that it will delist the common stock of MabVax by filing a Form 25 with the SEC to complete the delisting process. The delisting became effective ten days after the Form 25 was filed. The Company applied for listing on the OTCQB Venture Marketplace (the “OTCQB Marketplace”) on October 16, 2018, however, there can be no assurance of being listed while the SEC Action is underway.

Our Clinical Development Programs

MVT-1075 – our lead development program as a Radioimmunotherapy for Pancreatic Cancer

In June 2017, we initiated a Phase 1 clinical trial of our HuMab-5B1 radioimmunotherapy product MVT-1075 based on experience we gained through clinical studies of over 50 patients with either the antibody MVT-5873, or our imaging agent we designate as MVT-2163.

In April, the Company reported preclinical results for MVT-1075 at the American Association of Clinical Research (AACR) Annual Meeting, demonstrating suppression, and in some instances, regression, of tumor growth in xenograft animal models of pancreatic cancer, potentially making this product an important new therapeutic agent in the treatment of pancreatic, colon and lung cancers. Supporting the MVT-1075 RIT clinical investigation are the Company's successful MVT-5873 and MVT-2163 Phase 1a safety and target specificity data which were reported earlier this year at the annual meetings of the American Society for Clinical Oncology (ASCO) and the Society for Nuclear Medicine and Molecular Imaging (SNMMI), respectively. The combined results from 50 patients in the Phase 1 MVT-5873 and MVT-2163 studies established safety and provided significant insight into drug biodistribution and an optimal dosing strategy, which the Company has incorporated into the MVT-1075 program.

MVT-5873 – for the Treatment of Pancreatic Cancer

MVT-5873 as a Monotherapy in Late Stage Cancer ~~Patients~~ Patients – We reported results from our Phase 1a clinical trial of 32 patients ~~being~~ treated with our therapeutic antibody product candidate, MVT-5873, as a monotherapy in a poster presentation at the American Society of Clinical Oncology (“ASCO”) Annual Meeting on June 3, ~~which~~2017. ~~was~~MVT-5873 has been evaluated for safety and tolerability in patients with ~~advanced~~ advanced pancreatic cancer and other CA19-9 positive cancers,. inIn this a poster presentation, at the ~~American Society of Clinical Oncology (ASCO) Annual Meeting on June 3, 2017. The~~ Company highlighted that the ~~single~~ single agent MVT-5837 ~~appears~~appeared safe and well tolerated in patients at at biologically active doses based on the results of the Phase 1a trial. Furthermore, all patients in the Phase 1a trial were evaluated by RECIST 1.1 for tumor response, and the Company reported 11 patients achieved stable disease in this dose escalation safety trial of 32 patients.

The results of the Phase 1a trial with MVT-5873 ~~indicate~~support that this fully-human antibody targeting CA19-9 cancers can be administered at doses with acceptable safety and ~~with~~have a potentially positive impact on disease. The cancer antigen CA19-9 is broadly expressed in various cancers including pancreatic, colon, and small cell lung cancer making this antibody potentially useful for a larger patient population. Clinical signals from an identifiable subset of subjects enabled us to understand those patients most likely to respond to a MVT-5873 based therapy. AtWe ~~the~~plan ~~maximum~~to ~~tolerated~~continue ~~dose (MTD) established in~~to ~~this~~evaluate ~~trial,~~MVT-5873 weat ~~have~~higher ~~demonstrated an acceptable safety margin for the antibody~~doses.

MVT-5873 in Combination with a Standard of Care Chemotherapy – Based upon observations from ~~the~~ the first two cohorts of patients treated, ~~the~~we ~~Company~~are ~~is continuing~~evaluating further clinical development of MVT-5873 in combination with ~~gemcitabine~~ gemcitabine and nab-~~paclitaxal~~paclitaxel as a first line therapy for the treatment of patients newly diagnosed with pancreatic cancer. MabVax has treated seventeen ~~six~~ patients as of ~~October~~August 1224, ~~2017~~2018, ~~and is actively enrolling additional patients~~ with the objective of obtaining additional safety and tumor response (RECIST 1.1) data. for this treatment regimen. Dr. Eileen O’Reilly, Associate Director of the David M. Rubenstein Center for Pancreatic Cancer Research, attending physician, member at ~~Memorial~~MSK ~~Sloan Kettering Cancer Center~~ and ~~Professor~~ Professor of Medicine at Weill Cornell Medical College, is the lead investigator in the MVT-5873 Phase 1 clinical trial.

On February 12, 2018, we reported on interim results of the current cohort of the Phase 1 study, in which MVT-325873 was given in combination with nab-paclitaxel and gemcitabine to patients newly diagnosed with CA19-9 positive pancreatic cancer. MVT-5873 at a dose of 0.125 mg/kg when added to first-line chemotherapy was generally well tolerated by all subjects. At that time, all six patients in the current cohort demonstrated measurable tumor reductions, with four patients meeting the criteria for partial response (PR) and two patients meeting the criteria for stable disease (SD). We believe these results further confirm results reported on a portion of the cohort in late 2017. Patient CA19-9 levels, which are a prognostic indicator of the disease state, were markedly reduced in all subjects with this combination therapy. Due to adverse events potentially related to the combination of nab-paclitaxel, gemcitabine and MVT-5873, not seen in the monotherapy clinical study, the Company has suspended patient enrollment at the current dose. We are evaluating plans to enroll additional patients at a lower dose to further explore safety and response in a larger population.

MVT-5873 – for the Treatment of Pancreatitis

Pancreatitis is a severe and common medical condition that can lead to death or a chronic condition with significant morbidity, systemic inflammatory response and multiple organ dysfunction syndromes. Pancreatitis is also associated with a 16.5-fold elevated risk for developing pancreatic cancer. Best available treatment for pancreatitis is primarily supportive care consisting of rehydration, pain relief, nutritional support followed by antibiotic therapy, and surgery for biliary pancreatitis and other more severe cases. Acute and chronic pancreatitis in the United States accounts for 361,000 hospital admissions each year and for direct health care costs of $3.1 billion annually (Forsmark et al, NEJM 375;20 and Yadav et al, Pancreapedia, July 28, 2016).

Investigators at ~~MVT~~CSHL have made significant new discoveries elucidating the biological pathways that cause both acute and chronic pancreatitis. Investigators found that expression of CA19-~~2163~~9 –in the pancreas is sufficient to induce pancreatitis. Specifically, CA19-9 elevation resulted in rapid elevation of pancreatic enzymes in the blood, pancreatic infiltration of immune cells, acinar-to-ductal metaplasia and atrophy, as anwell ~~Imaging~~as increased ~~Agent~~proliferation. Investigators then explored the utility of CA19-9 as a therapeutic target for ~~Pancreatic~~both acute and chronic ~~Cancer~~pancreatitis. This avenue of treatment strategy exhibits potential given that turning off or blocking CA19-9 expression results in the normalization of pancreatic enzyme levels within four days following an acute episode of pancreatitis.

MVT-2163 was administered alone and in combination with MVT-5873 and was well tolerated in all cohorts. The only toxicities were infusion reactions that resolved on the day of the injection, with some patients requiring standard supportive medication. We reported that administering MVT-5873 prior to dosing MVT-2163 reduces liver uptake facilitating detection of liver metastases. In addition, we determined that the MVT-5873 cold antibody pre-dose ~~does~~ ~~not~~did not interfere with the uptake of MVT-2163 on cancer lesions.

In ~~Plan~~summary, the MVT-2163 product candidate demonstrated acceptable safety tolerability, pharmacokinetics and biodistribution in this trial. MVT-2163 also produced high quality PET images identifying both primary tumor and metastatic sites. We believe there was a promising correlation with diagnostic CT that warrants further studies correlating these findings with histopathology to assess the accuracy of MVT-2163 in identifying smaller metastatic nodes below the detection level of standard CT scans. We believe the continual increase in high SUVs on cancer lesions in this study supports the use of the Company’s MVT-1075 radioimmunotherapy product candidate, which utilizes the same antibody to deliver a radiation dose for ~~2018~~the treatment of patients with pancreatic, lung and colon cancers.

This information will then be used to determine if the new PET imaging agent can improve pre-~~2163~~surgical staging of patients with pancreatic ductal adenocarcinoma.

~~We currently plan to continue clinical development of MVT~~-1075 for the treatment of locally advanced or metastatic pancreatic cancer patients, by completing additional cohorts of patients in a dose escalation safety trial to continue to assess the safety and potential efficacy of this treatment, and expect to report results in the first quarter of 2018.28-

We also currently intend to continue clinical development of MVT-5873 in combination with gemcitabine and nab-paclitaxal in first line therapy for the treatment of patients newly diagnosed with pancreatic cancer. We have treated two cohorts of patients for a total of six patients through September 22, 2017 in this study; and have initiated enrollment for an additional cohort of patients with the objective of confirming early observations in the first quarter 2018.

Cancer

On ~~Comparison~~February 28, 2018, we announced positive interim results from the initial three-patient cohort of the ~~Year~~Phase ~~Ended~~1 ~~December~~clinical 31trial for MVT-1075, ~~2016~~which combines the demonstrated targeting specificity of the MVT-5873 antibody with the proven clinical success of a low-energy radiation emitter, 177Lutetium, often referred to as 177Lu. Results from the first three patients dosed in the initial cohort of this dose escalation Phase 1 safety trial demonstrated that MVT-1075 was reasonably well tolerated and accumulated on ~~2015~~tumor as evidenced by dosimetry measurements performed after the first dose. At this initial dose, two subjects met the criteria for stable disease (SD) and one met the criteria of progressive disease (PD) as measured using RECIST 1.1 criteria. Hematologic toxicities were manageable, and the Company is enrolling the first patient in the second cohort.

This Phase 1 first-in human dose escalation clinical trial, which began in June 2017, is an open-label, multi-center study evaluating the safety and efficacy of MVT-1075 in up to 22 patients for patients with PDAC or other CA19-9 positive malignancies including colon and lung cancers. The primary endpoint of this trial is to determine the maximum tolerated dose and safety profile in late stage patients with recurring disease who have failed prior therapies. Secondary endpoints include evaluating tumor response rate and duration of response by RECIST 1.1 and determining dosimetry and pharmacokinetics. This dose-escalation study utilizes a traditional 3+3 design and is based on experience we gained through prior clinical studies that treated 50 patients with either MVT-5873, or our imaging agent MVT-2163. The investigative sites are Honor Health in Scottsdale, Arizona, and MSK in New York City.

In April 2017, we reported preclinical results for MVT-1075 at the American Association of Clinical Research (AACR) Annual Meeting, demonstrating suppression, and in some instances, regression, of tumor growth in xenograft animal models of pancreatic cancer, potentially making this product candidate an important new therapeutic agent in the treatment of pancreatic, colon and lung cancers. Supporting the MVT-1075 RIT clinical investigation are the Company’s successful MVT-5873 and MVT-2163 Phase 1a safety and target specificity data which were reported earlier this year at the annual meetings of the ASCO and the SSNMMI, respectively. The combined results from 50 patients in the Phase 1 MVT-5873 and MVT-2163 studies established safety and provided significant insight into drug biodistribution and an optimal dosing strategy, which the Company has incorporated into the MVT-1075 program.

Asset Sales and License Agreements

License Grant to Y-mAbs Therapeutics, Inc.

On June 27, 2018, we entered into a Sublicense Agreement with Y-mAbs, pursuant to which we granted Y-mAbs an exclusive sublicense to a bi-valent ganglioside-based vaccine product candidate intended to treat neuroblastoma, a rare pediatric cancer.

Neuroblastoma is a rare solid tumor in childhood with only about 650 cases diagnosed each year in North America. The incidence is about 10.54 cases per 1 million per year in children younger than 15 years. About 37% are diagnosed as infants, and 90% are younger than 5 years at diagnosis, with a median age at diagnosis of 19 months. Neuroblastoma is responsible for 12% of all cancer deaths in children less than 15 years of age.

Total value of the transaction to MabVax is $1.3 million, $700,000 of which was paid upon execution of the agreement and $600,000 of which is to be paid within five (5) days of the first anniversary of the execution date, provided the agreement as not been terminated prior to the anniversary, plus a share of a Priority Review Voucher if granted by the FDA to Y-mAbs on approval of the vaccine and the Priority Review Voucher is subsequently sold. Additionally, Y-mAbs will be responsible for all further development of the product candidate as well as any downstream payment obligations related to this specific vaccine to MSK that were specified in the original MabVax-MSK license agreement. If Y-mAbs successfully develops and receives FDA approval for the Neuroblastoma vaccine product candidate, it is obligated to file with the FDA for a Priority Review Voucher. If this voucher is granted to Y-mAbs and subsequently sold, then MabVax will receive a percentage of the proceeds from the sale of the voucher by Y-mAbs.

The neuroblastoma vaccine product candidate was originally developed by Dr. Philip Livingston and colleagues at MSK and licensed as part of a broader portfolio of anti-cancer vaccines licensed to MabVax. MabVax filed for and was granted an Orphan Drug Designation for the neuroblastoma vaccine and has manufactured Phase II clinical supplies for a planned but not initiated clinical trial to be conducted with the consortium New Advances in Neuroblastoma Therapy (“NANT”). NANT is the only consortium of academic medical centers in the world solely dedicated to developing novel treatments and biomarkers for children with Neuroblastoma. Over the last several years, MabVax has shifted its focus and resources to the Company’s human antibody discovery and development programs that are currently in early stage clinical trials and have attracted partner interest.

Sale of Asset to Boehringer Ingelheim and Related Agreements

On July 6, 2018, we entered into the Asset Purchase Agreement with Boehringer Ingelheim, pursuant to which Boehringer Ingelheim purchased all of our rights to assets owned or controlled by us that related to a specific human antibody research and development program to identify and characterize antibodies that bind to an undisclosed glycan antigen. The transaction closed on July 6, 2018.

Pursuant to the Asset Purchase Agreement, MabVax may receive a total of $11 million, $4 million of which was received upfront and the remainder upon the achievement by Boehringer Ingelheim of various specified milestone events, plus further earn-out payments through the later of the expiration of the last to expire valid claim of the licensed program patent covering a Boehringer Ingelheim product, or ten (10) years from the date of first commercial sale of such Boehringer Ingelheim product on a country-by-country and product-by-product basis. The asset acquisition is separate and distinct from other programs under development at MabVax, enabling MabVax to retain all rights to its lead HuMab-5B1 antibody program which is in Phase 1 clinical trials as a therapeutic product candidate and as a diagnostic product candidate, as well as other antibody discovery programs from the Company’s antibody discovery portfolio targeting other cancer antigens.

MabVax discovered the antibody series at the center of this transaction from biological samples, originally from patients who were vaccinated against their solid tumors with a glycan antigen-containing vaccine. We believe our methods of discovery of fully human antibodies directly from vaccinated cancer patients has potential advantages, which include greater specificity and reduced toxicities.

Plan for Remainder of 2018

If we are able to secure additional funds, we intend to, among other things:

●

continue enrollment in our clinical study of MVT-5873 in combination with gemcitabine and nab-paclitaxel in first line therapy for the treatment of patients newly diagnosed with pancreatic cancer with the objective of confirming early observations seen to date, to enable discussions with potential strategic partners and investors.

●

enroll additional patients into the MVT-5873 monotherapy trial with the aim of establishing a higher maximum tolerated dose. We have submitted our Investigational New Drug Application (“IND”), to the FDA, for a revised protocol to enable continuation of the trial at higher doses.

●

support the continued development of the MVT-2163 imaging agent under the R01 grant made to MSK for the Phase 1b portion of this clinical program.

●

continue clinical development of MVT-1075 for the treatment of locally advanced or metastatic pancreatic cancer patients, by completing additional cohorts of patients in a dose escalation safety trial to continue to assess the safety and potential efficacy of this treatment; also, to enable discussions with potential strategic partners and investors.

●

Use a portion of existing supplies of MVT-5873 to pursue a proof of concept clinical trial of MVT-5873 in the treatment of pancreatitis.

We expect our total research and development expenditures in the next twelve months to remain approximately the same as we continue to fund the clinical studies of MVT-345873 in combination with gemcitabine and nab-paclitaxal in first line therapy for the treatment of patients newly diagnosed with pancreatic cancer, and MVT-2163 and begin clinical trials in MVT-1075 in 2017. In the event we are unable to obtain sufficient funding for clinical development of our therapies, we will need to defer completion of clinical trials until such funding is in place. If we are unable to obtain additional funding for our trials to complete clinical development, our total research and development expenditures will decrease substantially until the additional funding is raised.

We expect our total research and development expenditures in the next twelve months to increase as we continue to fund the clinical studies of MVT-5873 and MVT-2163 and begin clinical trials in MVT-1075 in 2017. In the event we are unable to obtain sufficient funding for clinical development of our therapies, we will need to defer completion of clinical trials until such funding is in place. If we are unable to obtain additional funding for our trials to complete clinical development, our total research and development expenditures will decrease substantially until the additional funding is raised.

The process of conducting the clinical research necessary to obtain FDA approval is costly and time consuming. Current FDA requirements for a new human drug to be marketed in the United States include:

●

the successful conclusion of preclinical laboratory and animal tests, if appropriate, to gain preliminary information on the product’s safety;

●

filing with the FDA of an IND, to conduct initial human clinical trials for drug candidates;

●

the successful completion of adequate and well-controlled human clinical trials to establish the safety and efficacy of the product candidate; and

●

filing by the Company and acceptance and approval by the FDA of an NDA for a product candidate to allow commercial distribution of the drug, which is beyond the scope of our financial resources. We intend on licensing or selling the technology prior to filing an NDA.

We consider the active management and development of our clinical pipeline to be crucial to our long-term success. The actual probability of success for each product candidate and clinical program may be impacted by a variety of factors, including, among others, the quality of the candidate, the validity of the target and disease indication, early clinical data, investment in the program, competition, manufacturing capability and commercial viability. Due to these and other factors, it is difficult to give accurate guidance on the anticipated proportion of our research and development investments or the future cash inflows from these programs.

General and Administrative Expenses

General and administrative expenses for the years ended December 31, ~~2016~~2017 and ~~2015~~2016 were $910,~~010~~526,~~450~~340 and $9,~~795~~010,~~163~~450, respectively.

Interest *Notand ~~meaningful~~other income (expense), net was $950,217 and $997,364 for the years ended December 31, 2017 and 2016, respectively. Interest expense in 2017 primarily relate to interest, amortization of financing costs and warrant amortization on the Company’s term loan from Oxford Finance LLC. The Company incurred interest costs of $576,124, amortization of financing costs of $166,104 and warrant amortization of $208,530 for the year ended December 31, 2017 compared to interest costs of $603,875, amortization of financing costs of $174,475 and warrant amortization of $219,039 for the year ended December 31, 2016.

The fair value of the warrants issued to Oxford Finance related to the term loan was recorded as a discount to the value of the note payable, and is amortized over the term of the loan. In addition, financing costs incurred related to the term loan are amortized over the term of the loan.

Warrant Liability

Change in fair value of warrant liability for the year ended December 31, 2016 and 2015 was $0 and $19,807, respectively. The decrease was mainly due to the restructuring the Company’s capital structure resulting in the elimination of the warrant liability as of December 31, 2015. We calculate the value of our warrant liability on a quarterly basis, or when other events and circumstances occur, using the Black-Scholes-Merton valuation model.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP. The preparation of these consolidated financial ~~statements~~ statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the ~~consolidated~~ consolidated financial statements as well as the reported revenues and expenses during the reporting periods. On an on-going basis, we evaluate our estimates and judgments related to our operating costs. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ significantly from these estimates under different assumptions or conditions.

Our critical accounting policies include:

Revenue recognition. Revenue from grants is based upon internal and subcontractor costs incurred that are specifically covered by the grant, including a facilities and administrative rate that provides funding for overhead expenses. NIH grants are recognized when MabVax Therapeutics incurs internal expenses that are specifically related to each grant, in clinical trials at the clinical trial sites, by subcontractors who manage the clinical trials, and provided the grant has been approved for payment. ~~U.S.~~NIH and other grant awards are based upon internal research and development costs incurred that are specifically covered by the grant, and revenues are recognized when MabVax Therapeutics incurs internal expenses that are related to the ~~approved~~ approved grant.

Any amounts received by MabVax Therapeutics pursuant to the NIH grants prior to satisfying our revenue recognition criteria are recorded as deferred revenue.

Table of Contents

Clinical trial expenses. We accrue clinical trial expenses based on work performed. In determining the amount to accrue, we rely on estimates of total costs incurred based on the enrollment of subjects, the completion of trials and other events defined in contracts. We follow this method because we believe reasonably dependable estimates of the costs applicable to various stages of a clinical trial can be made. However, the actual costs and timing of clinical trials are highly uncertain, subject to risks, and may change depending on aseveral ~~number of~~ factors. ~~Differences~~ Differences between the actual clinical trial costs and the estimated clinical trial costs that we have accrued in any prior period are recognized in the subsequent period in which the actual costs become known. Historically, these differences have not been material; however, material differences could occur in the future.

Stock-based compensation. Our stock-based compensation programs include grants of stock options and restricted stock to employees, non-employee directors and non-employee consultants. Stock-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense, under the straight-line method, over the employee, non-employee director or non-employee consultant’s requisite service period (generally the vesting period of the equity grant).

We account for equity instruments, including stock options and restricted stock, issued to employees and non-employees in accordance with authoritative guidance for equity -based payments. Stock options issued are accounted for at their estimated fair value determined using the Black-Scholes-Merton option-pricing model and restricted stock is accounted for using the grant date fair value of our common stock granted.

Income taxes. Significant judgment is required by management to determine our provision for income taxes, our deferred tax assets and liabilities, and the valuation allowance to record against our net deferred tax assets, which are based on complex and evolving tax regulations throughout the world. Our tax calculation is impacted by tax rates in the jurisdictions in which we are subject to tax and the relative amount of income earned in each jurisdiction. Our deferred tax assets and liabilities are determined using the enacted tax rates expected to be in effect for the years in which those tax assets are expected to be realized.

The effect of an uncertain income tax position is recognized as the largest amount that is “more-likely-than-not” to be sustained under audit by the taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained.

The realization of our deferred tax assets is dependent upon our ability to generate sufficient future taxable income. We establish a valuation allowance when it is more-likely-than-not that the future realization of all or some of the deferred tax assets will not be achieved. The evaluation of the need for a valuation allowance is performed on a jurisdiction-by-jurisdiction basis, and includes a review of all available evidence, both positive and negative. As of December 31, ~~2016~~2017, MabVax Therapeutics concluded that it was more-likely-than-not that its deferred tax assets would not be realized, and a full valuation allowance has been recorded.

The ~~Liquidity~~above listing is not intended to be a comprehensive list of all our accounting policies. In many cases, the accounting treatment of a transaction is specifically dictated by GAAP. See our audited consolidated financial statements and ~~Capital~~notes ~~Resources~~thereto included in our 2017 Annual Report on Form 10-K, which contain additional accounting policies and other disclosures required by GAAP.

From inception to December 31, 2016, we have financed our operations principally through net proceeds received from private equity and preferred stock financings, debt financings, and grants through the NIH and SBIR programs. We have experienced negative cash flows from operations each year since our inception. As of December 31, 2016, we had an accumulated deficit of $78,262,261. We expect to continue to incur increased expenses, resulting in losses, over at least the next several years due to, among other factors, our continuing and planned clinical trials and anticipated research and development activities.-33-

Liquidity and Capital Resources

To date, we have funded our operations primarily through government grants, proceeds from the sale of common and preferred stock, the issuance of debt, the issuance of common stock in lieu of cash for services, payments from collaborators and interest income. We have experienced negative cash flow from operations each year since our inception. As of December 31, 2017, we had an accumulated deficit of $111,053,637 and stockholders’ equity of $1,130,440. In February 2018 we completed a series of private placements totaling $2.7 million, net of approximately $55,000 in costs of financing. However, until such time as we have completed one or more license agreements of portions of our technology and we have sufficient funding from such licenses and financing transactions to continue to sustain operations, we anticipate continuing to incur substantial losses over at least the next several years to continue Phase I clinical trials of MVT-5873 in combination with a chemotherapy agent and MVT-1075 as a radioimmunotherapy agent for the treatment of various cancers, preclinical testing of follow-on antibody candidates, investor and public relations, SEC compliance efforts, and the general and administrative expenses associated with each of these activities. There can be no assurance that we will be able to achieve a license and earn revenues large enough to offset our operating expenses. We had cash of $885,710 and a working capital deficit of $4,598,748 as of December 31, 2017.

Sources and Uses of Cash

Due to the significant research and development expenditures and the lack of any approved products to generate revenue, we have not been profitable and have generated operating losses since we incorporated in 1988. As such, we have funded our research and development operations through government grants and contracts, sales of equity, debt, and collaborative arrangements with ~~corporate~~ corporate partners, and interest earned on investments. At December 31, ~~2016~~ 2017, we had available cash and cash equivalents of $3885,~~979,290~~710. Our cash and cash equivalents balances are held primarily in checking accounts. Cash in excess of immediate requirements is invested with regard to liquidity and capital preservation. Wherever possible, we seek to minimize the potential effects of concentration and degrees of risk.

Cash Flows from Operating Activities. ~~Cash~~ Cash used in operating activities for ~~2016~~ 2017 was $1210,~~363~~995,~~411~~511 compared to $1012,~~525~~363,~~182~~411 for the same period in ~~2015~~ 2016.

Working Capital. Working capital decreased to a working capital deficit of $1,396,656 at December 31, 2016 compared to a working capital surplus of $350,621 at December 31, 2015. The decrease in working capital was primarily due to increased capital usage during 2016 primarily related to the company’s clinical development programs.-34-

On May 19, 2017, we closed a public offering of 447,620 shares of common stock and 1,000,000 shares of newly designated Series G Preferred Stock, at $5.25 per share of common stock, after adjusting for the Reverse Stock Splits, and $1.75 per share of Series G Preferred Stock. The Series G Preferred Stock is initially convertible into 333,334 shares of common stock, after adjusting for the Reverse Stock Splits and subject to further adjustment for stock splits, stock dividends, recapitalizations, combinations, subdivisions or other similar events, to certain existing investors in the offering who, as a result of their purchases of common stock, would hold in excess of 4.99% of our issued and outstanding common stock, and elect to receive shares of our Series G Preferred Stock. We received $4,100,000 in gross proceeds, before estimate underwriting discounts, commissions and offering expenses of $416,217.

On July 27, 2017, we entered into a subscription agreement with an accredited investor pursuant to which we agreed to sell 50,715 restricted shares of common stock for $125,000. As part of the July 2017 Private Placement, the Company agreed to reprice the investor’s warrant to purchase 75,075 shares of common stock from $33.30 to $6.00 per warrant share and remove the cashless exercise feature. The transaction closed on August 2, 2017. The impact of repricing the warrants to $6.00 a share, which took effect on August 2, 2017, was immaterial, as the stock price on the date of the closing of the transaction was $2.10 and the warrants at $6.00 a share, and expired on October 10, 2017, unexercised.

On August 11, 2017, we entered into a security purchase agreement with a group of existing investors in the Company, where we sold 2,386.36 shares of Series J Preferred Stock, at a stated value of $550 per share, representing an aggregate of approximately $1,312,500 before offering expenses of $123,083 in an August 2017 financing. The shares of Series J Preferred Stock are convertible into shares of common stock (the “Series J Conversion Shares”) based on a conversion calculation equal to the stated value of the Series J Preferred Stock plus the base amount on such Series J Preferred Stock, as of such date of determination, divided by the conversion price. The stated value of each share of Series J Preferred Stock is $550 and the initial conversion price is $1.65 per share, each subject to adjustment for stock splits, stock dividends, recapitalizations, combinations, subdivisions or other similar events.

On September 11, 2017, the Company entered into subscription agreements with select accredited investors relating to the Company’s registered direct offering, issuance and sale of 1,333,334 shares of the Company’s common stock. The purchase price per share was $1.50. We received $2.0 million in gross proceeds, before offering expenses of $142,639. The offering closed September 14, 2017.

On September 22, 2017, the Company entered into additional subscription agreements with select accredited investors relating to the Company’s registered direct offering, issuance and sale of 672,043 shares of the Company’s common stock. The purchase price per share was $1.86. We received $1.25 million in gross proceeds, before offering expenses estimated at $14,000. The offering closed on September 27, 2017.

On October 10, 2017, the Company entered into additional subscription agreements with select accredited investors relating to the Company’s registered direct offering, issuance and sale of 256,410 shares of the Company’s common stock. The purchase price per share was $1.95. We received $500,000 in gross proceeds, before offering expenses totaling approximately $3,750. The offering closed on October 11, 2017.

We plan to fund the Company’s losses from operations for the foreseeable future through upfront and milestone payments from strategic collaborations and licensing arrangements, or other arrangements, or with equity or debt financings if strategic opportunities are not closed in a timely fashion, or at all. Further, to extend availability of existing cash available for our programs for the purpose of achieving one or more strategic transactions as well as our own development initiatives, we cut personnel in mid-2017 from 25 full time people to 11, and reduced other operating expenses following the completion of two Phase 1a clinical trials of our lead antibody HuMab 5B1, which has enabled us to reduce our expenditures on clinical trials. We expect to continue to develop MVT-5873 in combination with chemotherapy, and our radioimmunotherapy product MVT-1075, while exploring out-licensing opportunities for our technology for certain fields of use, as discussed further in Management’s Discussion and Analysis of Financial Condition and Results of Operations. However, we cannot be sure that completing one or more strategic transactions can be timely completed, or at all, or whether capital funding will be available on reasonable terms if strategic transactions are not timely. If we are unable to secure one or more strategic transactions or adequate additional funding, then we may be forced to make additional reductions in spending, incur further cutbacks in personnel, extend payment terms with suppliers, liquidate assets where possible, and/or suspend or curtail planned programs. If the Company does not meet its payment obligations to third parties as they come due, it may be subject to litigation claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

Based on receipt of $2.7 million in private placements, net of approximately $55,000 in costs of financing in February 2018, and without any other additional funding or receipt of payments from potential licensing agreements, we expect we will have sufficient funds to meet our obligations through April 2018. These conditions give rise to substantial doubt as to the Company’s ability to continue as a going concern. Any of these actions to reduce spending could materially harm the Company’s business, results of operations, and prospects. These conditions give rise to substantial doubt as to the Company’s ability to continue as a going concern. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

If the Company raises additional funds by issuing equity securities, substantial dilution to existing stockholders would result. If the Company raises additional funds by incurring debt financing, the terms of the debt may involve significant cash payment obligations as well as covenants and specific financial ratios that may restrict the Company’s ability to operate its business.

Working Capital. Our working capital deficit was $4,598,748 at December 31, 2017, as compared to a working capital deficit of $1,396,656 at December 31, 2016. The decrease in working capital was primarily due to increased capital usage during 2017 primarily related to the Company’s clinical development programs.

Going Concern. We believe our cash and cash equivalents as of December 31, 2017, together with $2.7 million in a private placement with accredited investors, net of approximately $55,000 in transaction costs in February 2018, and assuming no additional revenue generating license agreements are signed, will be sufficient to fund our projected operating requirements through approximately April 2018. In order to continue our current and future operations and continue our clinical product development programs through 2018 and beyond, we will depend substantially on our ability to obtain upfront and milestone payments from potential license and/or partnering agreements for use of our technologies in certain fields of use and raising capital through other financing transactions in a timely manner, or if at all. We are uncertain about our ability to raise sufficient funds to continue our existing operations after April 2018 without licensing and/or partnering transactions and additional financings. We have been exploring potential licensing and/or partnering transactions and other arrangement through which the value of our Company could be enhanced. We may raise funds through such potential arrangements with collaborators or others that may require us to sell product candidates that we might otherwise seek to develop or commercialize independently. Our failure to enter into licensing and/or partnering transactions or raise capital when needed could materially harm our business, financial condition and results of operations. See Risk Factors.

We anticipate that we will continue to incur substantial net losses into the foreseeable future as we: (i) continue our Phase I clinical trials of MVT-5873 in combination with chemotherapy and our Phase I clinical trial of our radioimmunotherapy product MVT-1075 for the treatment of various cancers, (ii) continue preclinical development activities related to developing a product targeting Tn for the treatment of breast cancer and small cell lung cancer and other product development candidates in our library, and (iii) monitor patients in clinical trials that have already completed their treatment regimens. Based on management’s assumptions for continuing to develop its existing pipeline of products without additional funding or licensing portions of our technology for particular uses, we expect we will have sufficient funds to meet our obligations through April 2018.

We plan to continue to fund our research and development and operating activities through strategic partnerships or other arrangements with organizations that have capabilities and/or products that are complementary to our own capabilities and/or products, licensing arrangements, and through public or private equity financings and debt financings or other arrangements if the strategic transactions are not timely, if at all. However, we cannot be sure that such strategic transactions or additional funds will be available on reasonable terms, or at all. If we are unable to secure strategic transactions or adequate additional funding, we may be forced to reduce spending, extend payment terms with suppliers, liquidate assets where possible, and/or suspend or curtail planned programs. In addition, if we do not meet our payment obligations to third parties as they come due, we may be subject to litigation claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to our management. Any of these actions could materially harm our business and results of operations.

If we raise additional funds by issuing equity securities, substantial dilution to our existing stockholders would result. If we raise additional funds by incurring debt financing, the terms of the debt may involve significant cash payment obligations as well as covenants and specific financial ratios that may restrict our ability to operate our business.

Our future capital uses and requirements depend on numerous factors, including the following:

●

the progress and success of preclinical studies and clinical trials of our product candidates;

●

the progress and number of research programs in development;

●

our ability to establish license agreements with third parties and reliance on receipt of payments from milestones;

OnOffices Leases. On September 2, 2015, the Company entered into a lease (the “Lease”) with AGP Sorrento Business Complex, L.P., for certain premises consisting of a total of approximately 14,971 square feet of office and laboratory space in buildings located at 11535-11585 Sorrento Valley Rd., San Diego, California, to serve as the Company’s corporate offices and laboratories (the “New Premises”). ~~Due~~Given ~~to the fact~~ that certain tenant improvements needed to be made to the New Premises before the Company could occupy the New Premises, the term of the Lease commenced on February 5, 2015. The Lease terminates six years after such term commencement date, unless earlier terminated in accordance with the Lease. ~~Pursuant~~Monthly rent tocommenced ~~the~~upon ~~terms~~occupancy ofat ~~the~~$2.38 ~~Lease~~per square foot, ~~the~~totaling ~~current~~$35,631, ~~monthly~~and ~~base~~escalates ~~rent~~at ~~paid~~an byannual ~~the~~rate ~~Company~~of is3% ~~$35,631,~~a ~~subject~~year over the tosix-year ~~annual~~term ~~increases~~of the lease as set forth in the Lease.

The Company has an option to extend the ~~Lease~~lease term for a single, five-year period. If the Lease term is extended for the optional five-year period, the monthly base rent will be adjusted based on fair market rental value. In addition to rent, the Company agreed to pay a portion of the taxes and utility, maintenance and other operating costs paid or accrued in connection with the ownership and operation of the property.

Our master lease and sublease of our facility located at 3165 Porter Drive in Palo Alto, California (the “Porter Drive Facility”) were terminated on February 28, 2013 and we entered into a termination agreement with ARE-San Francisco No. 24 (“ARE”) on February 19, 2013 to voluntarily surrender its premises. As a result of the termination agreement, we were relieved of further obligations under the master lease and further rights to rental income under the sublease and paid a termination fee of approximately $700,000. In addition to the termination fee, if we receive $15 million or more in additional financing in the aggregate, an additional termination fee of $590,504 will be due to ARE. The additional financing was achieved in 2015 and the termination fee is reflected on the balance sheet as an accrued lease contingency fee.

As a condition to the Lead Investor participating in the May 2017 Public Offering, the Company agreed to the requirement that we offer incentive shares (the “May 2017 Inducement Shares”) to investors from prior periods who participate in making a certain minimum required investment in the May 2017 Public Offering, as further described in Note 7, “Convertible Preferred Stock, Common Stock and Warrants” in the Notes to Consolidated Financial Statements.

Further, there are no financial penalties or repercussions to either party for nonperformance that would lead to a materially adverse impact on our financial statements.

Off-Balance Sheet Arrangements

We have no material off-balance sheet arrangements as defined in Regulation S-K 303(a)(4)(ii).

For the ~~Revenues~~three months ended September 30, 2018, we recognized $4,000,000 in revenues, as compared to no revenues for the same period in the prior year. The revenues in 2018 were due to the revenues recognized from the sale to Boehringer Ingelheim of all of our rights to certain assets owned or controlled by us that related to a specific human antibody research and development program to identify and characterize antibodies that bind to an undisclosed glycan antigen. The cost of revenues was $785,000 resulting in a gross profit of $3,215,000. The Company had no continuing obligations to provide any services under the contract, enabling the revenues to be recognized. Given the uncertainty of Boehringer Ingelheim achieving any of the future milestones, the Company did not recognize as revenue any of the future potential milestones as of September 30, 2018.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with ~~generally~~ ~~accepted accounting principles in the United States (“~~GAAP”). The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the ~~condensed~~ consolidated financial statements as well as the reported revenues and expenses during the reporting periods. On an on-going basis, we evaluate our estimates and judgments related to our operating costs. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ significantly from these estimates under ~~different~~ different assumptions or conditions.

Our critical accounting policies include:

Revenue recognition. Revenue from grants is based upon internal and subcontractor costs incurred that are specifically covered by the grant, including a facilities and administrative rate that provides funding for overhead expenses. NIH grants are recognized when we incur internal expenses that are specifically related to each grant, in clinical trials at the clinical trial sites, by subcontractors who manage the clinical trials, and provided the grant has been approved for payment. U.S. grant awards are based upon internal research and development costs incurred that are specifically covered by the grant, and revenues are recognized when we incur internal expenses that are related to the approved grant.

~~Any~~Effective January 1, 2018, the Company adopted ~~amounts~~Accounting ~~received~~Standards byCodification, usor ~~pursuant~~ASC, Topic 606, Revenue from Contracts with Customers (Topic 606), using the full retrospective transition method. Under this method, the Company would have been required to revise its financial statements, if applicable, for the ~~NIH~~years ~~grants~~ended ~~prior~~December 31, 2016 and 2017, and applicable interim periods within those years, as if Topic 606 had been effective for those periods. However, Topic 606 did not have any impact on the Company’s revenue recognition upon adoption. This standard applies to all ~~satisfying~~contracts ~~our~~with customers, except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments. Under Topic 606, an entity recognizes revenue when its customer obtains control of promised goods or services in an amount that reflects the consideration which the entity expects to receive in exchange for those goods and services. To determine revenue recognition ~~criteria~~for arrangements that an entity determines are ~~recorded~~within the scope of Topic 606, the entity performs the following five steps: (i) identify the contract(s) with the customer(s); (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity ~~deferred~~satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods and services it transfers to the customer. At contract inception, the Company assesses the goods or services promised within each contract that falls under the scope of Topic 606, determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

~~-42-~~ License and Other Revenues

The Company enters into licensing agreements which are within the scope of Topic 606, under which it licenses certain of its product candidates’ rights to third parties. The terms of these arrangements typically include payment of one or more of the following: non-refundable, up-front license fees; development, regulatory and commercial milestone payments; and royalties on Gross Profit of the licensed product, which will be classified as royalty revenues, if and when earned.

In determining the appropriate amount of revenue to be recognized as it fulfills its obligation under each of its agreements, the Company performs the five steps described above. As part of the accounting for these arrangements, the Company must develop assumptions that require judgment to determine the stand-alone selling price, which may include forecasted revenues, development timelines, reimbursement of personnel costs, discount rates and probabilities of technical and regulatory success.

Licensing of Intellectual Property – If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenue from non-refundable, up-front fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other performance obligations, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. The Company evaluates the measure of progress each reporting period, and, if necessary, adjusts the measure of performance and related revenue recognition.

Milestone Payments – At the inception of each arrangement that includes development milestone payments, the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal will not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the control of the Company or the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of such development milestones and any related constraint and, if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect license, collaboration and other revenues and earnings in their period of adjustment. To date, the Company has not recognized any milestone payments, because the milestones are not within the control of the Company and the technology is at an early stage of development, or the licensee has the ability to terminate the agreement before the milestone payment is due.

Royalties – For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and for which the license is deemed to be the predominant item to which royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized any royalty revenue from its license agreements.

Clinical trial expenses

We accrue clinical trial expenses based on work performed. In determining the amount to accrue, we rely on estimates of total costs incurred based on the enrollment of subjects, the completion of trials and other events defined in contracts. We follow this method because we believe reasonably dependable estimates of the costs applicable to various stages of a clinical trial can be made. However, the actual costs and timing of clinical trials are highly uncertain, subject to risks, and may change depending on several factors. Differences between the actual clinical trial costs and the estimated clinical trial costs that we have accrued in any prior period are recognized in the subsequent period in which the actual costs become known. Historically, these differences have not been material; however, material differences could occur in the future.

Stock-based compensation

Our stock-based compensation programs include grants of stock options and restricted stock to employees, non-employee directors and non-employee consultants. Stock-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense, under the straight-line method, over the employee, non-employee director or non-employee consultant’s requisite service period (generally the vesting period of the equity grant).

Impairment of Goodwill. The Company applies the GAAP principles related to Intangibles – Goodwill and Other related to performing a test for goodwill impairment annually. During the quarter ended September 30, 2017, due to the Company’s determination to explore and evaluate strategic options, we performed a step 1 analysis and assessed the market value of the Company to determine whether an impairment had taken place. Based upon the analysis performed no impairment was noted, therefore performing step 2 was not required. We concluded that no impairment of Goodwill had taken place during the quarter ended September 30, 2017. Further, in performing a qualitative assessment, we concluded no events and circumstances had taken place that would have indicated that an impairment had taken place.

The realization of our deferred tax assets is dependent upon our ability to generate sufficient future taxable income. We establish a valuation allowance when it is more-likely-than-not that the future realization of all or some of the deferred tax assets will not be achieved. The evaluation of the need for a valuation allowance is performed on a jurisdiction-by-jurisdiction basis, and includes a review of all available evidence, both positive and negative. As of September 30, ~~2017~~2018, the Company concluded that it was more-likely-than-not that its deferred tax assets would not be realized, and a full valuation allowance has been recorded.

LIQUIDITY AND CAPITAL RESOURCES

To date, we have funded our operations primarily through upfront payments from asset sales and license agreements, government grants, proceeds from the sale of common and preferred stock, the issuance of debt, the issuance of common stock in lieu of cash for services, payments from collaborators and interest income. We have experienced negative cash flow from operations each year since our inception. As of September 30, 2018, we had an accumulated deficit of $118,349,884. We expect to continue to incur increased expenses, resulting in losses, over the next several years due to, among other factors, our continuing and planned clinical trials and anticipated research and development activities, unless we can achieve additional licenses or asset sales of our product candidates that are under development, or revenues from research collaborations or services. There can be no assurance that we will be able to achieve additional license and sales revenue, or that such revenues would be large enough to offset our operating expenses. We had cash of $951,751 and a working capital deficit of $6,334,244 as of September 30, 2018.

Overview of 2018 Private Placements

The securities issued in connection with the February 2018 Private Placements and the May 2018 Private Placements were offered and sold solely to accredited investors in reliance on the exemption from registration afforded by Rule 506 of Regulation D and Section 4(a)(2) of the Securities Act. The Company entered into separate registration rights agreements with each of the investors in the February 2018 Private Placements and the May 2018 Private Placements, pursuant to which the Company agreed to undertake to file a registration statement to register the resale of the shares of common stock and the shares of common stock underlying the warrants and preferred stock. The Company also agreed to use reasonable best efforts to cause such registration statement to be declared effective and to maintain the effectiveness of the registration statement until all of such shares of common stock have been sold or are otherwise able to be sold pursuant to Rule 144 under the Securities Act, without any restrictions.

February 2018 Private Placements

In connection with the February 2018 Private Placements, the Company sold (i) an aggregate of 555,562 shares of its common stock for an aggregate purchase price of $1,250,000, or $2.25 per share, (ii) 5,000 shares of our newly designated 0% Series M Convertible Preferred Stock (the “Series M Preferred Stock”) for an aggregate purchase price of $1,500,000, or $300.00 per share, and (iii) warrants to purchase up to an aggregate of 855,561 shares of common stock each with an exercise price of $2.70 per share. The net proceeds of the February 2018 Private Placements were $2,700,000 after transaction costs of $50,000.

May 2018 Private Placements

Under the terms of the May 2018 Private Placements, we were required to offer an aggregate of 12,777.77 shares (the “May 2018 Inducement Shares”) of newly designated 0% Series O Preferred Stock (the “Series O Preferred Stock”) to investors who previously purchased securities in the February 2018 Private Placements and who also purchased securities in the May 2018 Private Placements with an aggregate purchase price of at least 40% of their investment amounts in the February 2018 Private Placements. Based on the closing of the offering, and participation of the Prior Investors who invested an aggregate of $830,000 (the “May 2018 Inducement Investors”), the Company issued an aggregate of 10,605.56 May 2018 Inducement Shares in the form of Series O Preferred Stock convertible into an aggregate of 1,060,556 shares of common stock. The May 2018 Private Placements closed on May 15, 2018, with the Company receiving gross proceeds totaling $830,000.

Working Capital

Our working capital deficit was $6,334,244 at September 30, 2018, as compared to a working capital deficit of $4,598,748 at December 31, 2017. The decrease in working capital was primarily due to increased capital usage during the first nine months of 2018 primarily related to the Company’s clinical development programs and professional services.

We anticipate we will continue to incur substantial net losses into the foreseeable future as we: (i) continue our Phase I clinical trials of MVT-5873 in combination with chemotherapy and our Phase I clinical trial of our radioimmunotherapy product candidate MVT-1075 for the treatment of various cancers, (ii) continue preclinical development activities related to developing other product candidates in our library, (iii) monitor patients in clinical trials that have already completed their treatment regimens, and (iv) incur legal expenses related to the SEC Action. Based on management’s assumptions for continuing to develop its existing pipeline of product candidates without additional funding or licensing portions of our technology for particular uses, we expect we will have sufficient funds to meet our obligations into December 2018. We may also incur costs and expenses in connection with liabilities under our organizational documents and indemnification agreements that we have with our officers and directors who may individually incur expenses in relation to the SEC Action.

We plan to continue to fund our debt securities, research and development and operating activities through additional strategic partnerships or other arrangements with organizations that have capabilities and/or products that are complementary to our own capabilities and/or product candidates, licensing arrangements, and through public or private equity financings and debt financings or other arrangements if the strategic transactions are not timely, if at all. However, we cannot be sure that such strategic transactions or additional funds will be available on reasonable terms, or at all. If we are unable to secure strategic transactions or adequate additional funding, we may be forced to reduce spending, extend payment terms with suppliers, liquidate assets where possible, suspend or curtail planned programs and/or cease our operations entirely. In addition, if we do not meet our payment obligations to third parties as they come due, including any payment we owe to Oxford Finance, we may be subject to litigation claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to our management.

Net cash used in operating activities was $8,702,932 for the nine months ended September 30, 2017, compared to $9,622,309 in the comparable period a year ago. The net cash used in both periods was primarily attributable to the net losses, adjusted to exclude certain non-cash items, primarily stock-based compensation and amortization of finance costs related to the term loan. Net cash used in operating activities for the nine months ended September 30, 2017 was also impacted by an increase of $403,210 in accounts payable and an increase in accrued clinical operation and site costs of $283,864.

The net cash used in investing activities for the nine months ended September 30, 2017 and 2016, amounted to $21,072 and $412,498, respectively, primarily as a result of discontinuing our in-house lab operations in the corresponding period.

Net cash provided by financing activities was $7,797,492 for the nine months ended September 30, 2017, compared to $12,891,935 in the comparable period in 2016. Net cash provided by financing activities for the nine months ended September 30, 2017 was attributable to the net proceeds from the May 2017 Private Placement and Public Offering during the second quarter of 2017, a Private Placement and Underwritten Offering in August 2017 and two Registered Direct Offerings in September 2017. Net cash provided by financing activities for the nine months ended September 30, 2016 was attributable to the net proceeds from the term loan during the first quarter in 2016.

Future Contractual Obligations

On September 2, 2015, the Company entered into the Lease with AGP Sorrento Business Complex, L.P., for certain premises consisting of office and laboratory space in buildings located at 11535 Sorrento Valley Rd., San Diego, California, to serve as the Company’s New Premises. Because certain tenant improvements needed to be made to the New Premises before the Company could take occupancy, the term of the Lease did not commence until the New Premises were ready for occupancy, which was on February 4, 2016. The Lease terminates on February 28, 2022, unless earlier terminated in accordance with the Lease. Pursuant to the terms of the Lease, the current monthly base rent paid by the Company is $37,801, subject to annual increases as set forth in the Lease.

The Company has an option to extend the Lease term for a single, five-year period. If the Lease term is extended for the optional five-year period, the monthly base rent will be adjusted based on fair market rental value. In addition to rent, the Company agreed to pay a portion of the taxes and utility, maintenance and other operating costs paid or accrued relating to the ownership and operation of the property.

Our master lease and sublease of our facility located at 3165 Porter Drive in Palo Alto, California were terminated on February 28, 2013, and we entered into a termination agreement with ARE on February 19, 2013 to voluntarily surrender its premises. Because of the termination agreement, we were relieved of further obligations under the master lease and further rights to rental income under the sublease and paid a termination fee of approximately $700,000. In addition to the termination fee, if we receive $15 million or more in additional financing, in the aggregate, an additional termination fee of $590,504 will be due to ARE. The additional financing was achieved in 2015 and the termination fee is reflected on the condensed consolidated balance sheet as an accrued lease contingency fee.

We ~~plan~~Recently toIssued ~~continue~~Accounting to fund the Company’s losses from operations and capital funding needs through equity or debt financings, strategic collaborations, licensing arrangements, government grants or other arrangements. Further, to extend availability of existing cash available for our programs for the purpose of achieving milestones or a strategic transaction, we have cut personnel from 25 full time people to 10, and reduced other operating expenses following the completion of two phase 1a clinical trials of our lead antibody HuMab 5B1, which has enabled us to reduce our expenditures on clinical trials. We continue to develop our radioimmunotherapy product MVT-1075 discussed further in Management’s Discussion and Analysis of Financial Condition and Results of Operations. Several members of management have volunteered to defer receiving portions of their salaries until one or more business transactions can be achieved. However, we cannot be sure that capital funding will be available on reasonable terms, or at all. If we are unable to secure adequate additional funding, we may be forced to make additional reductions in spending, incur further cutbacks in personnel, extend payment terms with suppliers, liquidate assets where possible, and/or suspend or curtail planned programs. In addition, if the Company does not meet its payment obligations to third parties as they come due, it may be subject to litigation claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.Standards

We ~~anticipate~~Adopted ~~that~~Accounting the Company will continue to incur net losses into the foreseeable future as we: (i) continue our clinical trial for the development of MVT1075 as a radioimmunotherapy, (ii) continue our clinical trial of MVT-5873 in combination with gemcitabine and nab-paclitaxal in first line therapy for the treatment of patients newly diagnosed with pancreatic cancer.; and (iii) continue operations as a public company. Based on receipt of the $125,000 private placement in July 2017, and financings of $1.3 million in August 2017, $2.0 million on September 14, $1.25 million on September 22, 2017, and $500,000 on October 10, 2017, and without any other additional funding or receipt of payments from potential licensing agreements, we expect we will have sufficient funds to meet our obligations until February 2018. These conditions give rise to substantial doubt as to the Company’s ability to continue as a going concern. Any of these actions could materially harm the Company’s business, results of operations, and prospects. These conditions give rise to substantial doubt as to the Company’s ability to continue as a going concern.

Because of the termination agreement, we were relieved of further obligations under the master lease and further rights to rental income under the sublease and paid a termination fee of approximately $700,000. In addition to the termination fee, if we receive $15 million or more in additional financing, in the aggregate, an additional termination fee of $590,504 will be due to ARE. The additional financing was achieved in 2015 and the termination fee is reflected on the condensed consolidated balance sheet as an accrued lease contingency fee.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments—Credit Losses (Topic326): Measurement of Credit Losses on Financial Instruments”. This ASU requires instruments measured at amortized cost to be presented at the net amount expected to be collected. Entities are also required to record allowances for available-for-sale debt securities rather than reduce the carrying amount. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We expect the adoption of this new standard will not have a material impact on our condensed consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15 (“ASU 2016-15”), “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” The standard provides guidance on eight (8) cash flow issues: (1) debt prepayment or debt extinguishment costs; (2) settlement of zero-coupon bonds; (3) contingent consideration payments after a business combination; (4) proceeds from the settlement of insurance claims; (5) proceeds from the settlement of corporate-owned life insurance policies; (6) distributions received from equity method investees; (7) beneficial interests in securitization transactions; and (8) separately identifiable cash flows and application of the predominance principle. ASU 2016-15 addresses how certain cash receipts and cash payments are presented and classified in the statement of cash flows. ASU 2016-15 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 with early adoption permitted. We expect the adoption of this new standard will not have a material impact on our condensed consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.” This ASU requires the recognition of the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The amendments in this ASU should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. We expect the adoption of this new standard will not have a material impact on our condensed consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-03, “Accounting Changes and Error Corrections (Topic 250) and Investments—Equity Method and Joint Ventures (Topic 323).” This ASU amends the disclosure requirements for ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” ASU No. 2016-02, “Leases (Topic 842) and ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This ASU states that if a registrant does not know or cannot reasonably estimate the impact that the adoption of the above ASUs is expected to have on the financial statements, then in addition to making a statement to that effect, the registrant should consider additional qualitative financial statement disclosures to assist the reader in assessing the significance of the impact that the standard will have on the financial statements of the registrant when adopted. This ASU was effective upon issuance. The adoption of this new standard did not have a material impact on our condensed consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, “Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” This ASU eliminates Step 2 from the goodwill impairment test. Instead, an entity should recognize an impairment charge for the amount by which the carrying value exceeds the reporting unit’s fair value, not to exceed the total amount of goodwill allocated to that reporting unit. This ASU is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. We expect the adoption of this new standard will not have a material impact on our condensed consolidated financial statements.

~~In January 2017, the FASB issued ASU~~With ~~No. 2017-01, “Business Combinations (Topic 805): Clarifying~~ the ~~Definition~~exception of ~~a Business.” This ASU clarifies~~ the ~~definition~~new ofstandards adiscussed ~~business~~above, ~~with~~there ~~the~~have ~~objective of adding guidance~~been tono ~~assist~~new ~~entities~~accounting ~~with~~pronouncements ~~evaluating~~that ~~whether~~have ~~transactions~~significance, ~~should be accounted for as acquisitions (~~or ~~disposals) of assets or~~ ~~businesses.~~potential ~~This ASU is effective for annual periods beginning after December 15~~significance, ~~2017,~~to ~~including interim periods within those periods.

Our Clinical Development Programs

MVT-5873 – for the Treatment of Pancreatic Cancer

MVT-5873 as a Monotherapy in Late Stage Cancer Patients – We reported results from our Phase 1a clinical trial of 32 patients treated with our therapeutic antibody product candidate, MVT-5873, as a monotherapy in a poster presentation at the American Society of Clinical Oncology (“ASCO”) Annual Meeting on June 3, 2017. MVT-5873 has been evaluated for safety and tolerability in patients with advanced pancreatic cancer and other CA19-9 positive cancers. In this poster presentation, the Company highlighted that the single agent MVT-5837 appeared safe and well tolerated in patients at biologically active doses based on the results of the Phase 1a trial. Furthermore, all patients in the Phase 1a trial were evaluated by RECIST 1.1 for tumor response, and the Company reported 11 patients achieved stable disease in this dose escalation safety trial of 32 patients.

The results of the Phase 1a trial with MVT-5873 support that this fully-human antibody targeting CA19-9 cancers can be administered at doses with acceptable safety and have a potentially positive impact on disease. The cancer antigen CA19-9 is broadly expressed in various cancers including pancreatic, colon, and small cell lung cancer making this antibody potentially useful for a larger patient population. Clinical signals from an identifiable subset of subjects enabled us to understand those patients most likely to respond to a MVT-5873 based therapy. We plan to continue to evaluate MVT-5873 at higher doses.

MVT-5873 in Combination with a Standard of Care Chemotherapy – Based upon observations from the first two cohorts of patients treated, we are evaluating further clinical development of MVT-5873 in combination with gemcitabine and nab-paclitaxel as a first line therapy for the treatment of patients newly diagnosed with pancreatic cancer. MabVax has treated seventeen patients as of August 24, 2018, with the objective of obtaining additional safety and tumor response (RECIST 1.1) data for this treatment regimen. Dr. Eileen O’Reilly, Associate Director of the David M. Rubenstein Center for Pancreatic Cancer Research, attending physician, member at MSK and Professor of Medicine at Weill Cornell Medical College, is the lead investigator in the MVT-5873 Phase 1 clinical trial.

On February 12, 2018, we reported on interim results of the current cohort of the Phase 1 study, in which MVT-5873 was given in combination with nab-paclitaxel and gemcitabine to patients newly diagnosed with CA19-9 positive pancreatic cancer. MVT-5873 at a dose of 0.125 mg/kg when added to first-line chemotherapy was generally well tolerated by all subjects. At that time, all six patients in the current cohort demonstrated measurable tumor reductions, with four patients meeting the criteria for partial response (PR) and two patients meeting the criteria for stable disease (SD). We believe these results further confirm results reported on a portion of the cohort in late 2017. Patient CA19-9 levels, which are a prognostic indicator of the disease state, were markedly reduced in all subjects with this combination therapy. Due to adverse events potentially related to the combination of nab-paclitaxel, gemcitabine and MVT-5873, not seen in the monotherapy clinical study, the Company has suspended patient enrollment at the current dose. We are evaluating plans to enroll additional patients at a lower dose to further explore safety and response in a larger population.

MVT-5873 – for the Treatment of Pancreatitis

Investigators at CSHL have made significant new discoveries elucidating the biological pathways that cause both acute and chronic pancreatitis. Investigators found that expression of CA19-9 in the pancreas is sufficient to induce pancreatitis. Specifically, CA19-9 elevation resulted in rapid elevation of pancreatic enzymes in the blood, pancreatic infiltration of immune cells, acinar-to-ductal metaplasia and atrophy, as well as increased proliferation. Investigators then explored the utility of CA19-9 as a therapeutic target for both acute and chronic pancreatitis. This avenue of treatment strategy exhibits potential given that turning off or blocking CA19-9 expression results in the normalization of pancreatic enzyme levels within four days following an acute episode of pancreatitis.

MVT-5873 specifically targets CA19-9, and subsequent studies have demonstrated that antibodies capable of binding to CA19-9 and blocking the downstream biological pathways of pancreatitis have a positive effect on ameliorating the disease. Combining the preclinical science supporting the use of the CA19-9 blocking antibodies in the treatment of pancreatitis with the clinically validated data and supplies of MVT-5873 already available gives MabVax the opportunity, assuming adequate funding, to move quickly into the clinic in a mid-stage proof of concept clinical trial in the near-term.

MVT-2163 – as an Imaging Agent for Pancreatic Cancer

We reported results from our Phase 1a clinical trial of ImmunoPET imaging agent product candidate, MVT-2163, in 12 patients with locally advanced or metastatic adenocarcinoma of the pancreas (“PDAC”) or other CA19-9 positive malignancies in a poster presentation and podium talk at the Society of Nuclear Medicine and Molecular Imaging (“SNMMI”) Annual Meeting held in Denver, Colorado on June 10-14, 2017.

The Phase 1a clinical trial of MVT-2163 Phase I trial was intended to evaluate our next generation diagnostic PET imaging agent in patients with PDAC or other CA19-9 positive malignancies. MVT-2163 (89Zr-HuMab-5B1) combines the well-established PET imaging radiolabel Zirconium-89, a positron emitting isotope typically labeled as 89Zr, with the targeting specificity of MVT-5873. We designed the trial to establish safety, pharmacokinetics, biodistribution, optimal time to obtain the PET image, and the amount of MVT-5873 to be administered as a blocking dose prior to administration of MVT-2163 to obtain optimized PET scan images.

As of July 2017, twelve (12) patients were treated in this first-in-human trial evaluating the safety and feasibility of MVT-2163 to image pancreatic tumors and other CA19-9 positive malignancies. MVT-2163 was administered alone and in combination with MVT-5873 and was well tolerated in all cohorts. The only toxicities were infusion reactions that resolved on the day of the injection, with some patients requiring standard supportive medication. We reported that administering MVT-5873 prior to dosing MVT-2163 reduces liver uptake facilitating detection of liver metastases. In addition, we determined that the MVT-5873 cold antibody pre-dose did not interfere with the uptake of MVT-2163 on cancer lesions.

In ~~Our~~April ~~Growth~~2018, the NIH awarded an R01 Research Grant to MSK for continued Phase 1b development of MVT-2163 as a PET diagnostic imaging agent. The R01 grant extends the Phase 1 work already completed by MabVax by evaluating MVT-2163 visual images and biopsies of ~~Core~~targeted ~~Business~~tissues illuminated ~~Strategy~~with the PET agent. This information will then be used to determine if the new PET imaging agent can improve pre-surgical staging of patients with pancreatic ductal adenocarcinoma. Since surgery is currently the only cure for pancreatic cancer and the success rate of surgical intervention is low, having a new diagnostic tool to more accurately assess the location and extent of the dissemination of the cancer has the potential to improve surgical outcomes. Additionally, these data can be used to support the dose and dose distribution determinations for the Company’s HuMab-5B1 antibody based radioimmunotherapy agent, MVT-1075, currently being evaluated in a Phase 1 trial. MabVax will support MSK in its research efforts and allow the clinical study to be conducted under a MabVax IND; however, the bulk of the costs will be borne by the NIH.

~~Our~~ ~~primary~~MVT-1075 ~~business~~– strategy is to develop our early antibody product candidates through proof of concept clinical trials, which may represent either phase I or phase II clinical trials depending on the program and extent of progress. Once through proof of concept clinical trials, we will decide whether to license, partner or sell those product candidates, or continue to develop the candidates depending on several variables such as ~~access~~a toRadioimmunotherapy ~~additional capital,~~for ~~cost of later stage clinical trials, risk of such~~Pancreatic ~~development efforts, and the value derived from licensing, partnering or selling those assets.~~Cancer

On ~~Our~~February ~~Clinical~~28, ~~Development~~2018, ~~Programs~~we announced positive interim results from the initial three-patient cohort of the Phase 1 clinical trial for MVT-1075, which combines the demonstrated targeting specificity of the MVT-5873 antibody with the proven clinical success of a low-energy radiation emitter, 177Lutetium, often referred to as 177Lu. Results from the first three patients dosed in the initial cohort of this dose escalation Phase 1 safety trial demonstrated that MVT-1075 was reasonably well tolerated and accumulated on tumor as evidenced by dosimetry measurements performed after the first dose. At this initial dose, two subjects met the criteria for stable disease (SD) and one met the criteria of progressive disease (PD) as measured using RECIST 1.1 criteria. Hematologic toxicities were manageable, and the Company is enrolling the first patient in the second cohort.

This Phase 1 first-in human dose escalation clinical trial, which began in June 2017, is an open-label, multi-center study evaluating the safety and efficacy of MVT-1075 –in ~~our~~up ~~lead~~to ~~development~~22 ~~program~~patients asfor patients with PDAC or other CA19-9 positive malignancies including colon and lung cancers. The primary endpoint of this trial is to determine the maximum tolerated dose and safety profile in late stage patients with recurring disease who have failed prior therapies. Secondary endpoints include evaluating tumor response rate and duration of response by RECIST 1.1 and determining dosimetry and pharmacokinetics.

Antibody Market Opportunity

The global monoclonal antibodies market was valued at $85 billion in 2015 and is expected to reach a value of $138 billion by 2024 (The Pharma Letter, February 11, 2016). Over the past couple of decades, the US FDA has approved more than a dozen monoclonal antibodies to treat certain cancers (cancer.org). Focused development of new monoclonal antibody-based drugs is expected to continue for multiple reasons. Over the last few years much has been learned about using the human immune system to treat cancer. Several recently approved antibody therapies have demonstrated efficacy in stimulating the human immune system to attack certain cancers. Targeted therapies can attack cancer cells while minimizing damage to normal cells in the patient. Antibodies are complex molecules and are difficult and expensive to duplicate with biosimilars and therefore have a potentially longer commercial life. Currently approved monoclonal antibodies are reimbursed at favorable levels from federal, state, and private insurance providers.

Our lead antibody candidate targets an antigen that is over expressed on many metastatic pancreatic, colon, breast, and small cell lung cancers. The term "over expressed" refers to the antigen being present on the surface of the cancer cell in very large numbers. The amount of antigen present in blood samples is used to monitor patients as elevated levels occur in the blood due to shedding into the blood from these cancer cells. Patients who develop metastatic disease have a significantly poorer prognosis for survival.

We believe there is a critical unmet medical need for new and better treatment for metastatic pancreatic and colon cancer. According to NCI’s SEER database (seer.cancer.gov), the five-year survival rate for patients with pancreatic cancer is just 7.7%. There are 53,000 new patients with pancreatic cancer diagnosed per year and more than half of these patients present at initial diagnosis with metastatic disease (Pancreatic Cancer Network’s Pancreatic Facts 2016). In 2016 pancreatic cancer moved from the fourth leading cause of cancer related death in the U.S. to third, surpassing breast cancer (American Cancer Society Cancer statistics 2016 report,). According to the SEER database, there are about 134,000 patients diagnosed with cancer of the colon and rectum per year in the US. The five-year survival rate for the 35% of patients with metastatic colon cancer that is locally spread is 71% and the five-year survival of the 35% of patients that have regional spread is only 13.5%.

In ~~connection~~Pancreatic ~~with~~Cancer ~~the~~Imaging August 2017 Offering, we agreed with the Lead Investor pursuant to the August 2017 Letter Agreement, to issue the Incentive Shares to Prior Investors as an incentive to invest in the August 2017 Offering. Such Prior Investors received a portion of 65,000 shares in the form of a new Series K Preferred Stock, allocated by the Lead Investor, and convertible into 6,500,000 shares of common stock, subject to stockholder approval, which was also approved in the October 2017 Special Meeting. The stated value of each share of Series K Preferred Stock is $0.01 and the conversion rate is the stated value of $0.01 divided by .0001, or one hundred (100) shares of common stock upon conversion of one (1) share of Series K Preferred Stock, each subject to adjustment for stock splits, stock dividends, recapitalizations, combinations, subdivisions or other similar event, and have a 4.99% beneficial ownership conversion blocker. In the event of a liquidation, dissolution or winding up of the Company, each share of Series K Preferred Stock will be entitled to a per share preferential payment equal to the par value, or $0.01 per share. All shares of the Company’s capital stock will be junior in rank to the Series K Preferred Stock at the time of creation, with respect to the preferences as to dividends, distributions and payments upon the liquidation, dissolution and winding-up of the Company, except for the Company’s Series D Preferred Stock, Series E Preferred Stock, Series F Preferred Stock, Series G Preferred Stock, Series H Preferred Stock, Series I Preferred Stock and Series J Preferred Stock. The Company recorded a deemed dividend of $3,120,000 in August 2017 in connection with issuing the Incentive Shares.Diagnosis

We believe that our radiolabeled HuMab-5B1 PET imaging antibody represents the only fully human derived monoclonal antibody agent in development with the potential of improving imaging in pancreatic cancer diagnosis over the standard of care (FDG-PET). Since the antigen targeted by the HuMab-5B1 antibody is over expressed on metastatic pancreatic cancer cells, this development effort represents a potentially important step forward in the diagnosis, staging, and assessment of patients newly diagnosed with pancreatic cancers. We believe that the market opportunity for a HuMab-5B1antibody-based radiopharmaceutical is significant in multiple ways. The ability of physicians to ~~August~~accurately ~~2017~~diagnose, ~~Letter~~stage, ~~Agreement~~and ~~also~~assess ~~specified~~treatment outcomes in pancreatic cancer would be very important. Accurate determinations on the extent of disease and resectability are essential to improve ~~following:~~outcomes in this cancer. We believe that limitations in FDG-PET imaging offers significant room for improvement in diagnostic technique and that accurate determinations on extent of disease and resectability are essential to improving outcomes in this cancer. Improvements in the sensitivity and specificity over FDG-PET could have a significant impact on improving diagnosis and clinical outcome.

Asset Purchase and License Agreement with Boehringer Ingelheim

On July 6, 2018, the Company entered into an Asset Purchase Agreement and License Agreement with Boehringer Ingelheim (the “Asset Purchase Agreement”) centered on MabVax's program targeting a glycan commonly overexpressed on multiple solid tumor cancers. Boehringer Ingelheim has acquired all rights in and to the program. MabVax received $4 million upon signing the agreement and receiving the funds and will receive an additional $7 million in connection with near-term milestones and downstream regulatory milestone payments plus further earn-out payments. The Company has not recognized as revenue as of June 30, 2018, any of the future milestones given the uncertainty of continuing development by Boehringer Ingelheim. The asset acquisition is separate and distinct from other programs under development at MabVax, enabling MabVax to retain all rights to its lead HuMab-5B1 antibody program which is in Phase 1 clinical trials as a therapeutic product candidate and as a diagnostic product candidate, as well as other antibody discovery programs from the Company's antibody discovery portfolio targeting other cancer antigens.

Cold Spring Harbor Laboratory License Agreement

On September 8, 2018, the Company entered into an agreement with Cold Spring Harbor Laboratory (“CSHL”), a nonprofit New York State education corporation, whereby the Company licensed the exclusive worldwide rights to certain discoveries and technology including exclusive interest in certain patent applications filed by the Company on behalf of CSHL for use of MVT-5873 as a treatment for pancreatitis. The Company paid $20,000 as an upfront license fee and will pay to CSHL a nonrefundable annual license maintenance fee of the same amount beginning on January 1, 2020 and continuing each year thereafter during the term of the agreement and will increase to $50,000 a year upon issuance of the first patent in connection with the technology. The annual license fee will be reduced for any patent prosecution and maintenance costs and will be fully creditable against any royalties or milestone payments earned during the year. Future milestone payments are in the aggregate less than $2.5 million, with royalties that range from 0.25% if no valid claim to patents, to 2.5% if there is a valid claim of the patent in the territory of sales.

OnSublicense ~~August~~Grant ~~14, 2017, the Chairman of the Compensation Committee, acting on behalf of the Board of Directors sent a letter~~ to each executive of the Company stating that the Board deems it in the best interests of the Company to request that the executive voluntarily defer a portion of his regular salary to help with cash flow of the Company. On August 16 and August 21, 2017, Paul Resnick, M.D. and Paul Maffuid, Ph.D., respectively gave notice of good reason (as that term is defined in their employment agreements or “Good Reason”) for termination of their employment. The Company had 30 days from the notification date under each of their employment agreements to cure their concerns. In oral discussions with each executive the President and Chief Executive Officer communicated on behalf of the Compensation Committee the Company’s intention to provide additional equity compensation in return for salary deferrals. Given the perceived uncertainty about the Company’s plans at the time for addressing the concerns of Dr. Resnick and Dr. Maffuid, and that nothing in writing had been provided as possible equity compensation, they each submitted their notices to the Company of good reason for termination. Further, they each expressed in oral conversations that they wanted to remain employed by the Company. The Company cured each executive’s concerns within the 30Y-~~day~~mAbs ~~cure period~~Therapeutics, ~~by reinstating the deferred salary for Dr~~Inc.

~~The global monoclonal antibodies market was valued at $85 billion in 2015 and is expected to reach a value of $138 billion by 2024 (The Pharma~~ Letter~~, February 11, 2016).~~ ~~Over~~Agreement ~~the~~Regarding ~~past~~Future ~~couple~~Financing of decades, the US FDA has approved more than a dozen monoclonal antibodies to treat certain cancers (cancer.org). Focused development of new monoclonal antibody based drugs is expected to continue for multiple reasons. Over the last few years much has been learned about using the human immune system to treat cancer. Several recently approved antibody therapies have demonstrated efficacy in stimulating the human immune system to attack certain cancers. Targeted therapies can attack cancer cells while minimizing damage to normal cells in the patient. Antibodies are complex molecules and are difficult and expensive to duplicate with biosimilars and therefore have a potentially longer commercial life. Currently approved monoclonal antibodies are reimbursed at favorable levels from federal, state, and private insurance providers.Transactions

~~Rockefeller~~In ~~University~~addition, ~~Collaboration~~the Company agreed to the following in the August 2017 Letter Agreement:

In July 2015, we entered into a research collaboration agreement with Rockefeller University's Laboratory of Molecular Genetics and Immunology (“Rockefeller”). We provided antibody material to Rockefeller, which is exploring the mechanism of action of constant region (Fc) variants of the HuMab 5B1 in the role of tumor clearance. We will supply additional research materials as requested by the university, which is evaluating ways to optimize the function. Rockefeller is using that material to explore the mechanism of action of constant region (Fc) variants of the HuMab-5B1 in the role of tumor clearance and to seek to optimize the therapeutic effect. The current agreement allows researchers at Rockefeller to conduct research on antibodies discovered by us with the objective of improving their ability to kill cancer cells. If a viable drug candidate emerges from this collaboration, we have the first option to negotiate a royalty bearing license to Rockefeller’s technology or Rockefellers’ interest in technology jointly owned with us to improve our antibody for clinical and commercial development. If we and Rockefeller fail to reach agreement to a license of the drug candidate containing the combined technologies within six months’ notice by either party seeking a license, then either party may freely license jointly owned property to any third party and share equally any consideration received from the licensee.●

Marketing and Sales

We currently do not have an internal sales force and do not intend to commercialize on our own any of our product candidates that receive FDA approval. We intend to license, or enter into strategic alliances with, larger companies in the biopharmaceutical businesses, which are equipped to manufacture, market and/or sell our products, if any, through their well-developed manufacturing capabilities and distribution networks. We intend to license some or all of our worldwide patent rights to more than one third party to achieve the fullest development, marketing and distribution of any products we develop.

Manufacturing and Raw Materials

We currently use, and expect to continue ~~the~~to use ~~of,~~ contract manufacturers to ~~for the~~ manufacture of our product candidates. Our contract manufacturers are subject to extensive governmental regulation. Regulatory authorities in ~~our~~the ~~markets~~pharmaceutical industry require that pharmaceutical products be manufactured, packaged and labeled in conformity with current cGMPs. We intend to establish a quality control and quality assurance program, which will include a set of standard operating procedures and specifications designed to ensure that our products are manufactured in accordance with cGMPs, and other applicable domestic and foreign regulations.

We currently do not have any clinical or commercial antibody-based therapeutic manufacturing capabilities. We ~~may~~likely orwill ~~may not manufacture the products we develop, if any. We intend to~~ use ~~contract~~ contract manufacturers for the manufacture of our product candidates.

Competition

The drug development and medical diagnostic industries are characterized by rapidly evolving technology and intense competition. Our competitors include development and diagnostic companies that have significantly more financial, technical, and marketing resources. In addition, there are a significant number of biotechnology companies working on evolving technologies that may supplant our technology or make it obsolete. Academic institutions, government agencies, and other public and private research organizations are also conducting research activities and may commercialize product candidates either on their own or through joint ventures that compete with one or more of our product candidates. We are aware of certain development projects for products to prevent or treat certain diseases targeted by us. The existence of these potential products or other products or treatments of which we are not aware, or products or treatments that may be developed in the future, may adversely affect the desirability and commercial success of any product candidate for which we receive FDA approval.

There are aseveral ~~number of~~ companies ~~working~~engaged in ~~the area of~~ human antibody development and imaging that could compete in similar clinical areas, including disease detection, therapeutic response monitoring and minimal disease detection. These companies include ~~AbCellera~~ AbCellera Biologics, Inc., Agenus Inc., Atreca, Inc., Immunomedics, Inc., Theraclone Sciences Inc., and Trellis Bioscience.

Government Regulation

In the United States, pharmaceutical products are subject to extensive regulation by the FDA. The Federal ~~Food,~~ Drug and Cosmetic Act and ~~other~~ other federal and state statutes and regulations, govern, among ~~other~~ other things, the research, development, testing, manufacture, storage, recordkeeping, approval, labeling, promotion and marketing, distribution, post-approval monitoring and reporting, sampling, and import and export of pharmaceutical products. The FDA has very broad enforcement authority and failure to abide by ~~applicable~~ applicable regulatory requirements can result in administrative or ~~judicial~~ judicial sanctions being imposed on us, including warning letters, ~~refusals~~ refusals of government contracts, clinical holds, civil ~~or criminal~~ penalties, injunctions, restitution, disgorgement of profits, recall or seizure of products, total or partial suspension of production or distribution, withdrawal of approval, refusal to approve pending applications, and criminal prosecution.

FDA Approval Process

We believe that our product candidates will be regulated by the FDA as drugs. No manufacturer may market a new drug until it has submitted a New Drug Application, (“or NDA”), to the FDA, and the FDA ~~has~~ has approved it. The steps required before the FDA may approve an ~~NDA~~ NDA generally include:

●

preclinical laboratory tests and animal tests conducted in compliance with FDA’s good laboratory practice requirements;

●

development, manufacture and testing of active pharmaceutical product and dosage forms suitable for human use in compliance with current good manufacturing practices, or GMP;

●

the submission to the FDA of an investigational new drug application, (“or IND”), for human clinical testing, which must become ~~effective~~ effective before human clinical trials may begin;

●

adequate and well-controlled human clinical trials to establish the safety and efficacy of the product for its specific ~~intended use(s);~~

intended use(s);

●

the submission to the FDA of a New Drug Application, or NDA; and

●

FDA review and approval of the NDA.

Preclinical tests include laboratory evaluation of the product candidate, as well as animal studies to assess the potential safety and efficacy of the product candidate. The conduct of the pre-clinical tests must comply with federal regulations and requirements including good laboratory practices. We must submit the results of the preclinical tests, together with manufacturing information, analytical data and a proposed clinical trial protocol to the FDA as part of an IND, which must become effective before we may commence human clinical trials. The IND will automatically become effective 30 days after its receipt by the FDA, unless the FDA raises concerns or questions before that time about the conduct of the proposed trials. In such a case, we must work with the FDA to resolve any outstanding concerns before clinical trials can proceed. We cannot be sure that submission of an IND will result in the FDA allowing clinical trials to begin, or that, once begun, issues will not arise that suspend or terminate such trials. The study protocol and informed consent information for patients in clinical trials must also be submitted to an institutional review board for approval. An institutional review board may also require the clinical trial at the site to be halted, either temporarily or permanently, for failure to comply with the institutional review board’s requirements or may impose other conditions.

Clinical trials involve the administration of the product candidate to humans under the supervision of qualified investigators, generally physicians not employed by or under the trial sponsor’s control. Clinical trials are typically conducted in three sequential phases, though the phases may overlap or be combined. In Phase 1, the initial introduction of the drug into healthy human subjects, the drug is usually tested for safety (adverse effects), dosage tolerance and pharmacologic action, as well as to understand how the drug is taken up by and distributed within the body. Phase 2 usually involves studies in a limited patient population (individuals with the disease under study) to:

●

evaluate preliminarily the efficacy of the drug for specific, targeted conditions;

●

determine dosage tolerance and appropriate dosage as well as other important information about how to design larger Phase 3 trials; and

●

identify possible adverse effects and safety risks.

Table of Contents

Phase 3 trials generally further evaluate clinical efficacy and test for safety within an expanded patient population. The conduct of the clinical trials is subject to extensive regulation, including compliance with good clinical practice regulations and guidance.

The FDA may order the temporary or permanent discontinuation of a clinical trial at any time or impose other sanctions if it believes that the clinical trial is not being conducted in accordance with FDA requirements or presents an unacceptable risk to the clinical trial patients. We may also suspend clinical trials at any time on various grounds.

The results of the preclinical and clinical studies, together with other detailed information, including the manufacture and composition of the product candidate, are submitted to the FDA in the form of an NDA requesting approval to market the drug ~~as well as a user fee of over $2 million~~. FDA approval of the NDA is required before marketing of the product may begin in the U.S. If the NDA contains all pertinent information and data, the FDA will “file” the application and begin review. The FDA may “refuse to file” the NDA if it does not contain all pertinent information and data. In that case, the applicant may resubmit the NDA when it contains the missing information and data. Once the submission is accepted for filing, the FDA begins an in-depth review. The FDA has agreed to certain performance goals in the review of ~~NDAs~~new drug applications. Most such applications for non-priority drug products are reviewed within 10 months. The review process, however, may be extended by FDA requests for additional information, preclinical or clinical studies, clarification regarding information already provided in the submission, or submission of a risk evaluation and mitigation strategy. The FDA may refer an application to an advisory committee for review, evaluation and recommendation as to whether the application should be approved. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. Before approving an NDA, the FDA will typically inspect the facilities at which the product candidate ~~and/or~~ ~~the active pharmaceutical ingredient~~ is manufactured and will not approve the product candidate unless GMP compliance is satisfactory. FDA also typically inspects facilities responsible for performing animal testing, as well as clinical investigators who participate in clinical trials. The FDA may refuse to approve an NDA if applicable regulatory criteria are not satisfied, or may require additional testing or information. The FDA may also limit the indications for use and/or require post-marketing testing and surveillance to monitor the safety or efficacy of a product. Once granted, product approvals may be withdrawn if compliance with regulatory standards is not maintained or problems are identified following initial marketing.

The testing and approval process requires substantial time, effort and financial resources, and our product candidates may not be approved on a timely basis, if at all. The time and expense required to perform the clinical testing necessary to obtain FDA approval for regulated products can frequently exceed the time and expense of the research and development initially required to create the product. The results of preclinical studies and initial clinical trials of our product candidates are not necessarily predictive of the results from large-scale clinical trials, and clinical trials may be subject to additional costs, delays or modifications due to aseveral ~~number of~~ factors, including difficulty in obtaining enough patients, investigators or product candidate supply. Failure by us to obtain, or any delay in obtaining, regulatory approvals or in ~~complying~~ complying with requirements could adversely affect the commercialization of product candidates and our ability to receive product or royalty revenues.

Other Regulatory Requirements

After approval, drug products are subject to extensive continuing regulation by the FDA, which include company obligations to manufacture products in accordance with Good Manufacturing Practice, or GMP, maintain and provide to the FDA updated safety and efficacy information, report adverse experiences with the product, keep certain records and submit periodic reports, obtain FDA approval of certain manufacturing or labeling changes, and comply with FDA promotion and advertising requirements and restrictions. Failure to meet these obligations can result in various adverse consequences, both voluntary and FDA-imposed, including product recalls, withdrawal of approval, restrictions on marketing, and the imposition of civil fines and criminal penalties against the NDA holder. In addition, later discovery of previously unknown safety or efficacy issues may result in restrictions on the product, manufacturer or NDA holder.

We and any manufacturers of our products are required to comply with applicable FDA manufacturing requirements contained in the FDA’s GMP regulations. GMP regulations require among other things, quality control and quality assurance as well as the corresponding maintenance of records and documentation. The manufacturing facilities for our products must meet GMP requirements to the satisfaction of the FDA pursuant to a pre-approval inspection before we can use them to manufacture our products. We and any third-party manufacturers are also subject to periodic inspections of facilities by the FDA and other authorities, including procedures and operations used in the testing and manufacture of our products to assess our compliance with applicable regulations.

With respect to post-market product advertising and promotion, the FDA imposes several complex regulations on entities that advertise and promote pharmaceuticals, which include, among others, standards for direct-to-consumer advertising, promoting drugs for uses or in-patient populations that are not described in the drug’s approved labeling (known as “off-label use”), industry-sponsored scientific and educational activities, and promotional activities involving the internet. Failure to comply with FDA requirements can have negative consequences, including adverse publicity, enforcement letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties. Although physicians may prescribe legally available drugs for off-label uses, manufacturers may not market or promote such off-label uses.

Changes to some of the conditions established in an approved application, including changes in indications, labeling, or manufacturing processes or facilities, require submission and FDA approval of a new NDA or NDA supplement before the change can be implemented. An NDA supplement for a new indication typically requires clinical data similar to that in the original application, and the FDA uses the same procedures and actions in reviewing NDA supplements as it does in reviewing NDAs.

Adverse event reporting and submission of periodic ~~adverse experience~~ reports is required following FDA approval of an NDA. The FDA also may require post-marketing testing, known as Phase 4 testing, ~~risk~~ ~~evaluation and~~ risk minimization ~~strategies,~~ action plans and surveillance, ~~as well as annual reports on matters relating~~ to ~~the NDA, to~~ monitor the effects of an approved product or place conditions on an approval that could restrict the distribution or use of the product.

Outside the United States, our ability to market a product is contingent upon receiving marketing authorization from the appropriate regulatory authorities. The requirements governing marketing authorization, pricing and reimbursement vary widely from jurisdiction to jurisdiction. At present, foreign marketing authorizations are applied for at a national level, although within the European Union registration procedures are available to companies wishing to market a product in more than one European Union member state.

We are also subject to various environmental, health and safety regulations including those governing laboratory procedures and the handling, use, storage, treatment, and disposal of hazardous materials. From time to time, and in the future, our operations may involve the use of hazardous materials.

Orphan Drugs

Under the Orphan Drug Act of 1983, the FDA may grant orphan drug designation to drugs or biologics intended to treat a rare disease or condition, which is generally defined as a disease or condition that affects fewer than 200,000 individuals in the United States. Orphan drug designation must be requested before submitting an NDA. After the FDA grants orphan drug designation, the generic identity of the drug 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. The first applicant to receive FDA approval for a particular active ingredient to treat a particular disease with FDA orphan drug designation is entitled to a seven-year exclusive marketing period in the United States for that product, for that indication. During the seven-year exclusivity period, the FDA may not approve any other applications to market the same drug or biologic for the same disease, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity. Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease or condition, or the same drug or biologic for a different disease or condition. Among the other benefits of orphan drug designation are tax credits for certain research and a waiver of the NDA application user fee.

Foreign Regulation

Before our products can be marketed outside of the U.S., they are subject to regulatory approval of the respective authorities in the country that the product will be marketed. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary widely from country to country. No action can be taken to market any product in a country until an appropriate application has been approved by the regulatory authorities in that country. The current approval process varies from country to country, and the time spent in gaining approval varies from that required for FDA approval. In certain countries, the sales price of a product must also be approved. The pricing review period often begins after market approval is granted. Even if a product is approved by a regulatory authority, satisfactory prices might not be approved for such product.

While we intend to market our products outside the United States in compliance with our respective license agreements, we have not made any applications with non-U.S. authorities and have no timeline for such applications or marketing.

Properties

We entered into a lease agreement in August 2012 as amended in August 2015 with a lease term that ended on September 30, 2015, for 5,955 square feet of office space at 11588 Sorrento Valley Road in San Diego, California. Upon expiration of the lease in September 2015, prior to the availability of our new facility, we continued to lease this space on a month-to-month basis from October 2015 through January 2016 at the rate of $11,017 per month.

In September 2015, we entered into a lease agreement with AGP Sorrento Business Complex, L.P. for a lease of approximately 14,971 rentable square feet of office and research facilities located at 11535 Sorrento Valley Road, San Diego, California 92121 to serve as our corporate offices and laboratories. Due to the fact that certain tenant improvements needed to be made to the premises before we could take occupancy, the facilities were not ready until early 2016. We moved from our previous facility at 11588 Sorrento Valley Road, into our new space in and took occupancy on February 4, 2016. Monthly rent commenced upon occupancy at $2.38 per square foot, totaling $35,631, and will escalate at an annual rate of 3% a year over the six-year term of the lease as set forth in the Lease.

Legal Proceedings

~~From~~SEC ~~time~~Complaint to time, we have become involved in various legal proceedings that arise in the ordinary course of business or otherwise. Legal proceedings are subject to inherent uncertainties as to timing, outcomes, costs, expenses and ~~time~~SEC expenditures by our management and others on our behalf. Although there can be no assurance, based on information currently available, we believe that the outcome of legal proceedings that are pending or threatened against us will not have a material effect on our financial condition. However, the outcome of any of these matters is neither probable nor reasonably estimable.Action

As disclosed in a press release and a ~~Employees~~Current Report on Form 8-K filed with the SEC on January 30, 2018, the Company reported that it received notice on January 29, 2018, from the SEC of an investigation (along with the SEC Complaint, defined below, the “SEC Action”). We stated at that time that we believe the SEC is investigating (i) potential violations by the Company and its officers, directors and others of Section 10(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and Section 17(a) of the Securities Act of 1933, as amended (as amended, the “Securities Act”); and (ii) potential violations by multiple holders of our preferred stock, who are among those included in the Aggregated Investors (as defined on Page 78), of the reporting and disclosure requirements imposed by Section 13(d) of the Exchange Act and pursuant to Schedules 13D and 13G. We further believe the SEC Action pertains to our relationships with certain of the Aggregated Investors, including (i) the circumstances under which those certain Aggregated Investors invested in the Company and whether certain Aggregated Investors have acted as an undisclosed group in connection with their investment; (ii) the manner with or in which those individuals and entities may have sought to control or influence the Company and its leadership since their respective investments (and the extent to which those efforts to control or influence have been successful); and (iii) our prior disclosures regarding the control of the Company and beneficial ownership of our common and preferred stock included in our registration statements filed in 2017 and 2018 and in our Exchange Act reports.

AsOn September 7, 2018, the SEC filed a complaint (the “SEC Complaint”) in the U.S. District Court for the Southern District of ~~December~~New 14York against the following Aggregated Investors: Barry C. Honig, ~~2017~~John Stetson, Michael Brauser, John R. O'Rourke III, Mark Groussman, Phillip Frost, Alpha Capital Anstalt, ATG Capital LLC, Frost Gamma Investments Trust, GRQ Consultants, Inc., Grander Holdings, Inc., Melechdavid, Inc., OPKO Health, Inc., HS Contrarian Investments, LLC, and Southern Biotech, Inc.

Honig et al., No. 1:18-cv-01875 (S.D.N.Y. 2018). In the Complaint, the SEC alleges a variety of misconduct with respect to the Investor Defendants’ transactions and/or ~~one~~relationships ~~part~~with three public issuers, including a public issuer identified as “Company C,” which we understand to be MabVax Therapeutics Holdings, Inc. With respect to “Company C” in particular, the SEC alleges certain of the Investor Defendants manipulated the price of the Company’s securities by writing, or causing to be written, false or misleading promotional articles, and a variety of other manipulative trading practices. The SEC further alleges certain of the Investor Defendants filed false reports of their beneficial ownership or failed to file reports of their beneficial ownership when required to do so. The SEC claims that, by engaging in this and other alleged actions in the SEC Complaint, the Investor Defendants and other defendants violated the anti-~~time~~fraud ~~employee~~and many other provisions of the Exchange Act, the Securities Act, and SEC Rules promulgated thereunder. ~~Our~~The ~~employees~~SEC Complaint ~~are~~does not ~~represented~~assert byany claims against the Company or any of ~~collective~~its ~~bargaining~~directors ~~unit~~or officers, ~~and~~nor weotherwise ~~believe~~allege ~~our~~that ~~relations~~the ~~with~~Company ~~our~~or ~~employees~~any ~~are~~of ~~good~~its directors or officers were culpable participants in the misconduct allegedly undertaken by the Investor Defendants.

We have cooperated with the SEC in connection with the SEC Action. Although the SEC has not asserted claims against the Company or any of its directors or officers, we cannot predict whether the SEC Action ultimately will conclude in a manner adverse to the Company or any of its directors and officers, or in a manner adverse to the Investor Defendants or other of the Company’s current or former stockholders. We also cannot predict when the SEC Action or any related matters may conclude, or how any such matters or resolution may impact how the Company is perceived by the market, potential partners and potential investors in our securities.

Company Filed Complaint Against Sichenzia Ross Ference LLP

On September 10, 2018, the Company filed, in the Superior Court of California, County of San Diego, a complaint (the “Sichenzia Complaint”) against Sichenzia Ross Ference LLP, a law firm that previously represented the Company in certain corporate, securities, and SEC matters (“Sichenzia”), and eight current Sichenzia partners, and one former Sichenzia partner, Harvey Kesner, MabVax Therapeutics Holdings, Inc. v. Sichenzia Ross Ference LLP et al., No. 37-2018-00045609-CU-PN-CTL. The Sichenzia Complaint asserts claims for negligent professional practice, breach of fiduciary duty, breach of contract, unjust enrichment, deceit, and fraud by the defendants. The Company is evaluating additional claims it may have against others in connection with the same or similar subject matter.

Delaware Order Granting Petition for Relief

On September 20, 2018, the Court entered an order validating (i) issuances of common stock upon conversions of the Company’s preferred stock occurring between June 30, 2014 and February 12, 2018, and (ii) stockholder approval of corporate actions presented to the Company’s stockholders from June 30, 2014 to February 12, 2018. In so doing, the Court granted the Delaware Petition, filed on July 27, 2018, in order to rectify the uncertainty regarding whether shares of the Company’s common stock were validly issued upon conversion of the Company’s preferred stock from June 30, 2014 to February 12, 2018.

Class Action and Derivative Complaints

In re MabVax Therapeutics Securities Litigation, Case No. 18-cv-1160-BAS-NLS. On June 4, 2018, and August 3, 2018, two securities class action complaints were filed by purported stockholders of the Company in the United States District Court for the Southern District of California (the “U. S. District Court”) against the Company and certain of its current officers. On September 6, 2018, the U.S. District Court consolidated the two actions and appointed lead plaintiffs. On October 10, 2018, lead plaintiffs filed their consolidated complaint, which, in addition to naming the Company and certain current officers as defendants, also names certain investors as defendants. The consolidated complaint alleges, among other things, that the defendants violated Sections 10(b) and 20(a) of the Exchange Act, and Rule 10b-5 thereunder, by misleading investors about problems with the Company’s internal controls, improper calculation of its beneficial ownership, and improper influence by certain investors. The consolidated complaint also alleges that some of the investor defendants violated Section 9 of the Exchange Act by manipulating the Company’s stock price. The consolidated complaint seeks unspecified damages, interest, fees and costs. The current deadline to respond to the consolidated complaint is December 6, 2018.

Liesman v. Hansen et al., Case No. 18-cv-2237-BTM-WVG. On September 26, 2018, a shareholder derivative complaint was filed in the United States District Court for the Southern District of California. The complaint arises from similar allegations as In re MabVax Therapeutics Securities Litigation but asserts a state law breach of fiduciary duty claim against certain of the Company’s current and former directors and officers. In particular, the complaint alleges that the defendants breached their fiduciary duties by failing to implement the necessary controls to ensure that certain financial disclosures and disclosures concerning stock ownership were accurate. Plaintiff seeks, on behalf of the Company, damages, fees, costs, and equitable relief.

Jackson v. Hansen et al., Case No. 18-cv-2302-BAS-MSB-BGS. On October 4, 2018, a shareholder derivative complaint was filed in the United States District Court for the Southern District of California. The complaint arises from similar allegations as In re MabVax Therapeutics Securities Litigation and Liesman v. Hansen et al. but, in addition to a breach of fiduciary duty claim, also includes causes of action for unjust enrichment, abuse of control, gross mismanagement and waste of corporate assets. Plaintiff seeks, on behalf of the Company, damages, fees, costs, and equitable relief. The deadline to respond to the complaint is December 21, 2018.

Nasdaq De-listing and Application for Listing on the OTCQB Marketplace

On July 2, 2018, the Listing Qualifications Department of The Nasdaq Stock Market (the “Staff”) notified the Company of its determination to delist the Company’s securities. In this notice, the Staff indicated their determination was based upon the Company’s failure to timely file all required reports with the SEC per Nasdaq listing rule 5250(c)(1), and for the Company’s non-compliance with the $2.5 million stockholders’ equity requirement per Nasdaq listing rule 5550(b)(1). The Company elected not to appeal the Staff’s decision and, as a result, on July 2, 2018, the Company received a letter from the Staff indicating trading of the Company’s common stock would be suspended on The Nasdaq Capital Market at the open of business on Wednesday, July 11, 2018. On July 11, 2018, the Company’s common stock began trading on the OTC Pink, continuing under the symbol MBVX. The Hearing Department of The Nasdaq Stock Market notified us on September 24, 2018, that it would announce the delisting of our common stock. On September 26, 2018, The Nasdaq Stock Market issued a press release and posted a notice to its website announcing it would delist our common stock and file a Form 25 with the SEC to complete the delisting. The delisting becomes effective ten (10) days after the Form 25 is filed with the SEC.

The Company applied for listing on the OTCQB Marketplace on October 16, 2018, of which there can be no assurance of being listed while the SEC Action is underway.

Resignation and Appointment of Members of the Board of Directors

Following the resignations, in a separate action, the Company’s Board of Directors appointed the Company’s Chief Financial Officer, Gregory Hanson, as a member of the Board of Directors. Mr. Hanson has served as the Company’s Chief Financial Officer since July 2014, and of its subsidiary, MabVax Therapeutics, Inc., since February 2014. Mr. Hanson has over 30 years' experience serving as the CFO, financial executive and director of public and private life sciences and hi-tech companies. Since October 2016, he has served as a member of the board of directors of a private pharmaceutical contract research organization.

Notice of Events of Default under Loan and Security Agreement

The Company believes it has been in compliance with all applicable covenants set forth in the Loan Agreement from its inception on January 15, 2016, through November 19, 2018. However, on August 14, 2018, the Company received a letter from Oxford Finance (the “Notice”) asserting certain events of default had occurred under the loan agreement with Oxford Finance as a result of certain events the Company reported as having occurred, including, without limitation, (i) the resignation of the Company’s external auditor, CohnReznick LLP (“CohnReznick”), effective August 3, 2018, and its withdrawal of its audit reports for the years 2014 through 2017, (ii) the resignation of four (4) members of the Board of Directors, effective as of July 31, 2018, and (iii) the delisting of the Company’s common stock from The Nasdaq Stock Market LLC on July 11, 2018 (collectively, the “Alleged Default Events”). The Company informed Oxford Finance that it disputes the Alleged Default Events, individually or collectively, constitute a “Material Adverse Change” or other event of default under the Loan Agreement. In addition, the Company already engaged a new auditor, Haskell & White LLP, effective August 22, 2018, and on September 20, 2018, the Court ratified the Delaware Petition. The Company also has applied for listing on the OTCQB Venture Marketplace (the “OTCQB Marketplace”); however, there can be no assurances of being listed while the SEC Action is underway.
