Chimerix Reports First Quarter 2020 Financial Results and Provides Operational Update

DSTAT Explored as a Potential Novel Treatment for the Current Pandemic While an NDA is Being Prepared for Brincidofovir to Address a Potential Future Pandemic

DURHAM, N.C., May 07, 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 first quarter ended March 31, 2020 and provided an operational update.

“Responding to the COVID-19 global pandemic, we recently announced our accelerated program for dociparstat sodium (DSTAT) to combat acute lung injury (ALI) in COVID-19 patients,” stated Mike Sherman, Chief Executive Officer of Chimerix. “As we've learned more about the manifestations of COVID-19 and how it causes death in the most serious cases, it has become clear that DSTAT’s mechanisms may be uniquely positioned to address multiple aspects of the virus’ progression, including ALI and coagulative disorders that have led to a number of other conditions, including amputations, pulmonary embolisms and stroke. As a result, DSTAT has the potential to prevent the disease progression necessitating the use of mechanical ventilation, improve survival and potentially accelerate recovery.”

“Given the urgent need for effective treatments for COVID-19 related ALI, we expect to begin dosing patients in this Phase 2/3 clinical trial this month, with data from the first safety cohort from the Phase 2 portion of the study to be available in the second half of this year.

“The COVID-19 pandemic has also highlighted the importance of our global preparedness for a variety of viral outbreaks. Chimerix has been at the forefront of these measures working with the U.S. government to develop brincidofovir (BCV) for smallpox. Preparing BCV for the U.S. Strategic National Stockpile (SNS) is a critical element to protect the population from this deadly virus, whether a potential outbreak occurs naturally or through a bioterror attack. To that end, we were very pleased to receive the U.S. Food and Drug Administration’s (FDA) clearance to initiate a rolling New Drug Application (NDA) for BCV as a medical countermeasure for smallpox. We look forward to finalizing our submission mid-year and to a potential procurement contract to enable the addition of BCV to the SNS,” added Mr. Sherman.

Recent Highlights

• Received clearance from the FDA for a rolling submission of its NDA for the approval of BCV as a medical countermeasure for smallpox
• Received clearance from the FDA to initiate a Phase 2/3 Study of DSTAT in ALI patients with COVID-19
• Received clearance from the FDA to initiate a Phase 3 trial of DSTAT in Acute Myeloid Leukemia (AML) based on review of final protocol.

Expected Upcoming Milestones

• Completion of NDA submission of BCV mid-2020
• Completion of Phase 2 portion of DSTAT trial in COVID-19 in second half of 2020
• Initiation of Phase 3 trial of DSTAT in first line AML
• Potential procurement agreement for BCV prior to FDA decision on smallpox NDA
• FDA decision on BCV smallpox NDA in 2021
• Completion of manufacturing of approximately $100 million of BCV product for SNS by mid-2021.

The company previously announced a plan to initiate a Phase 3 clinical study of DSTAT for the treatment of AML in 2020 and has subsequently announced its delay due to the ongoing COVID-19 pandemic. The Company’s current operational focus is on executing the DSTAT study in ALI patients with COVID-19. Next steps on the proposed AML study will be determined in the coming months.

General and administrative expenses decreased to $3.2 million for the first quarter of 2020, compared to $7.7 million for the same period in 2019.

Loss from operations was $10.9 million for the first quarter of 2020, compared to a loss from operations of $18.8 million for the same period in 2019.

The Company expects to end the year with approximately $70 million in cash and cash equivalents at the end of 2020.

About Chimerix

Chimerix is a development-stage biopharmaceutical company dedicated to accelerating the advancement of innovative medicines that make a meaningful impact in the lives of patients living with cancer and other serious diseases. Its 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. In vitro and in vivo animal model data support DSTAT’s potential to reduce the inflammation and cellular infiltration associated with acute lung injury and address coagulation disorders associated with COVID-19 pathology (HMGB1 and PF4). Separately, DSTAT inhibits the activities of several key proteins implicated in the viability of AML blasts and leukemic stem cells in the bone marrow during chemotherapy (e.g., CXCL12, selectins, HMGB1, elastase). Randomized AML Phase 2 data suggest that DSTAT may also accelerate platelet recovery post-chemotherapy via inhibition of PF4, a negative regulator of platelet production that impairs platelet recovery following chemotherapy. The company is conducting a randomized, double-blind, placebo-controlled, Phase 2/3 trial to determine the safety and efficacy of DSTAT in adults with severe COVID-19 who are at high risk of respiratory failure. The Phase 2 portion of the study will enroll 24 subjects to confirm the maximum safe dose and will then expand by an additional 50 patients (74 total) at the selected dose. A formal analysis of all endpoints, including supportive biomarkers will be performed at the conclusion of the Phase 2 portion of the study. Contingent upon positive results, the Phase 3 portion of the study will enroll approximately 450 subjects.

BCV is an antiviral drug candidate in development as a medical countermeasure for smallpox. For further information, please visit the Chimerix website, www.chimerix.com.
