Chimerix Reports Fourth Quarter and Year End 2019 Financial Results and Provides Operational Update

– Successful DSTAT End of Phase 2 Meeting with FDA Confirms Phase 3 Readiness; First Patient Visit Expected mid-2020 in 1L AML –
– Brincidofovir pre-NDA Meeting Scheduled with FDA, on Track for mid-2020 NDA Filing –– Conference Call at 8:30 a.m. ET Today –DURHAM, N.C., Feb. 25, 2020 (GLOBE NEWSWIRE) — Chimerix (NASDAQ:CMRX), a biopharmaceutical company focused on accelerating the development of medicines to treat cancer and other serious diseases, today reported financial results for the fourth quarter and full-year ended December 31, 2019 and provided an operational update.“The transformation and progress we made in 2019 has laid the foundation for Chimerix to achieve a number of value-creating milestones in 2020,” said Mike Sherman, Chief Executive Officer of Chimerix. “The team has continued to execute extremely well as we plan to file our first New Drug Application (NDA) for brincidofovir (BCV) as a medical countermeasure for smallpox and advance our promising dociparstat sodium (DSTAT) program into pivotal Phase 3 clinical development as a front-line treatment for acute myeloid leukemia (AML).”Fourth Quarter and Recent HighlightsPhase 3 Pivotal Trial of DSTAT in Front-line AML PatientsChimerix recently conducted an end of Phase 2 meeting with the U.S. Food and Drug Administration (FDA) related to the Company’s development of DSTAT in AML. Following that meeting, Chimerix incorporated FDA’s feedback on key elements of the Phase 3 clinical trial and has since submitted a full protocol for final FDA review.   Chimerix plans to initiate a Phase 3 trial mid-year of DSTAT in combination with standard chemotherapy (cytarabine plus anthracycline, or “7+3”) in newly diagnosed AML patients.The proposed Phase 3 trial will be a randomized, double-blind trial of approximately 570 newly diagnosed AML patients. The trial will include patients 60 years of age or older who have an intermediate or adverse genetic risk profile.  It will also include patients between 18 and 60 years of age who have an adverse genetic risk profile. Patients will be randomized 1:1 to receive DSTAT in combination with standard of care cytarabine plus anthracycline (7+3) induction and cytarabine consolidation chemotherapy or to receive standard of care (7+3) induction and consolidation chemotherapy alone.  Patients with FLT-3 mutations will be allowed in the study and will be eligible to receive midostaurin.The primary endpoint of the proposed trial will be overall survival (OS). In addition, FDA has indicated that event-free survival (EFS), using complete response with hematologic recovery to define induction success (CR), is acceptable as an endpoint for regulatory approval. Other endpoints to be evaluated in the proposed trial include minimal residual disease (MRD), relapse-free survival (RFS), time to hematologic recovery, and induction response. In order to supplement the previously reported data from the pilot and Phase 2 trials and provide additional evidence of DSTAT’s mechanism of action, the proposed Phase 3 trial includes an early assessment of comparative CR and MRD rates among the first 80 evaluable patients. This data is expected to be unblinded, reported publicly, and available for ongoing analysis of later endpoints. Prior to potential unblinding, this data will be reviewed by an independent Data Monitoring Committee (DMC).  The DMC will have the discretion to maintain blinding of the data from this early assessment in the event the DSTAT arm shows exceptional advantages to the control arm on CR and/or MRD, at certain pre-specified thresholds, which would allow inclusion of these patients in the final analysis.   The Company expects to incur approximately $15 million in clinical trial expenses up to and including this early assessment.BCV as a Medical Countermeasure for SmallpoxIn January, Chimerix presented data in support of BCV as a potential treatment for smallpox at the 2020 American Society for Microbiology (ASM) Biothreats Meeting in Arlington, Virginia. The presentation highlighted independent experiments performed in two lethal animal models of smallpox. In these studies, either rabbits or mice were inoculated with rabbitpox or ectromelia (mousepox) virus, respectively, to determine the survival benefit conferred by BCV treatment in animals acutely infected with these orthopoxviruses. Animals were randomized to receive either placebo or BCV at varying time intervals post infection. In both studies, animals that received BCV, even when administered late post-infection, demonstrated a statistically significant survival advantage relative to placebo.Data from these studies are intended to address the requirement under the FDA Animal Efficacy Rule for two different animal models of efficacy. Chimerix is collaborating with the Biomedical Advanced Research and Development Authority (BARDA) for the development of BCV as a potential medical countermeasure for smallpox. This rule allows for testing the efficacy of investigational drugs in animal models for diseases which cannot be evaluated in human clinical studies.In cooperation with BARDA, Chimerix has scheduled a pre-NDA meeting with FDA to review the final efficacy and safety data in preparation to submit an NDA.  Pending the outcome of this meeting, Chimerix intends to submit a BCV NDA for smallpox in mid-2020. The Company’s operating and manufacturing plan assumes entering into a procurement contract with BARDA in 2020 and preparation for delivery of BCV into the Strategic National Stockpile in 2021.Fourth Quarter 2019 Financial ResultsChimerix’s balance sheet at December 31, 2019 included $113.5 million of capital available to fund operations, no debt, and approximately 61.6 million outstanding shares of common stock.Chimerix reported a net loss of $3.5 million, or $0.06 per basic and diluted share, for the fourth quarter of 2019.

The Company’s two clinical-stage development programs are dociparstat sodium (DSTAT) and brincidofovir (BCV).Dociparstat sodium is a potential first-in-class glycosaminoglycan compound derived from porcine heparin that has low anticoagulant activity but retains the ability to inhibit activities of several key proteins implicated in the retention and viability of AML blasts and leukemic stem cells in the bone marrow during chemotherapy (e.g., CXCL12, selectins, HMGB1, elastase).  Mobilization of AML blasts and leukemic stem cells from the bone marrow has been associated with enhanced chemosensitivity and may be a primary mechanism accounting for the observed increases in survival  endpoints in Phase 2 with DSTAT versus placebo. Randomized Phase 2 data suggest that DSTAT may also accelerate platelet recovery post-chemotherapy via inhibition of platelet factor 4, a negative regulator of platelet production that impairs platelet recovery following chemotherapy. BCV is an antiviral drug candidate in development as a medical countermeasure for smallpox.
