Item 7.01 Regulation FD Disclosure.

On December 10, 2024, Chimerix, Inc. (the “Company”) made available an updated corporate presentation (the “Presentation”) that the Company intends to use, in whole or in part, in meetings with investors, analysts and others. The Presentation can be accessed through the “Investors” section of the Company’s website. A copy of the Presentation is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated by reference herein.

The information in this Item 7.01 and the attached Exhibit 99.1 is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that Section. The information in this Item 7.01 and the attached Exhibit 99.1 shall not be incorporated by reference into any registration statement or other document pursuant to the Securities Act of 1933, as amended.

Item 8.01 Other Events.

On December 9, 2024, the Company announced its plan to submit a complete new drug application (“NDA”) seeking accelerated approval for dordaviprone (“ONC201”) as a treatment for recurrent H3 K27M-mutant diffuse glioma in the United States before year-end 2024, following extensive dialogue with the U.S. Food and Drug Administration (the “FDA”). ONC201 is a novel first-in-class small molecule imipridone that selectively targets the mitochondrial protease ClpP and dopamine receptor D2 (“DRD2”), which has received Rare Pediatric Disease Designation for H3 K27M-mutant glioma and is eligible to apply for a Rare Pediatric Disease Priority Review Voucher (“PRV”). The Company intends to apply for a Rare Pediatric Disease PRV in the upcoming NDA submission.

The following recent program milestones and additional supportive data were extensively discussed with the FDA and will be included in the NDA:

•Substantial enrollment of the Phase 3 ACTION study;

•Phase 2 objective response rate of the 50-patient primary efficacy analysis assessed by blinded independent central review as the primary basis of efficacy in the NDA;

•Several response assessments, including the most contemporary response assessment criteria for gliomas, Response Assessment in Neuro-Oncology 2.0 (“RANO 2.0”), under which ONC201 demonstrated an objective response rate of 28%, a median duration of response of 10.4 months and a median time to response of 4.6 months;

•Additional clinical data sets and patient narratives supportive of the primary efficacy analysis observed to date;

•Clinical and nonclinical demonstration of dordaviprone-driven reversal of the central hallmark of H3 K27M-mutant glioma, H3K27 trimethyl loss;

•Comprehensive safety database of glioma patients and healthy volunteers that supports a favorable benefit/risk profile observed to date; and

•Comprehensive clinical pharmacology and chemistry, manufacturing, and controls studies.

The Company will request Priority Review for the NDA. If granted, the resulting six-month FDA review period is expected to result in a potential initial Prescription Drug User Fee Act (“PDUFA”) action date for accelerated approval in the third quarter of 2025.

Should the Company be awarded a Rare Pediatric Disease PRV and thereafter sell such Rare Pediatric Disease PRV to a third party, 50% of the net proceeds from such sale would be payable to the former securityholders of Oncoceutics, Inc. pursuant to the Agreement and Plan of Merger with Oncoceutics, Inc., dated as of January 7, 2021.

In addition, the Company expects to determine by early 2025 the recommended dosing for planned Phase 2 clinical trials of ONC206. ONC206 is a second generation ClpP agonist and DRD2 antagonist that has demonstrated monotherapy anti-cancer activity in non-clinical models and is currently in dose escalating clinical trials for adult and pediatric patients with primary central nervous system tumors.
