– Blinded Independent Central Review (BICR) of ONC201 Registration Cohort in Recurrent H3 K27M-mutant Glioma Expected in Fourth Quarter 2021 –

– Conference Call at 8:30 a.m. ET Today –

DURHAM, N.C., Aug. 05, 2021 (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 second quarter ended June 30, 2021 and provided an operational update.

“We made considerable progress throughout the first half of 2021, highlighted by the acquisition of Oncoceutics, the initiation of the Phase 3 DASH AML trial, and the FDA approval of TEMBEXA as a medical countermeasure for smallpox. This approval is an important milestone as it marks Chimerix’s first FDA approved drug and is the first smallpox antiviral approved for all age groups, including infants, with an available oral solution for patients who have difficulty swallowing,” said Mike Sherman, Chief Executive Officer of Chimerix. “Looking ahead to the balance of the year, we expect to report the efficacy analysis by BICR for ONC201 and complete TEMBEXA manufacturing to support U.S. national preparedness.”

Recent Highlights

TEMBEXA for Smallpox

In June, the FDA granted TEMBEXA tablets and oral suspension approval for the treatment of smallpox. TEMBEXA is approved for adult and pediatric patients and is the first and only smallpox therapy approved for neonates. The oral suspension formulation is particularly important for patients who have difficulty swallowing due to age or medical status.

TEMBEXA potentially fills an important role as a treatment countermeasure to smallpox; it has a differentiated mechanism of action, a relatively high barrier to resistance and available evidence suggests it can be used in patients who have received the other approved smallpox antiviral treatment.   By year-end, Chimerix expects to complete initial TEMBEXA drug product manufacturing in order to satisfy a potential procurement contract to support national preparedness in the United States.

Imipridones and ONC201

Chimerix’s acquisition of Oncoceutics, Inc., expands the Company’s oncology franchise with a late-stage, novel class of small molecule anti-cancer compounds. Oncoceutics’ lead product candidate, ONC201, has been shown in clinical testing to selectively induce tumor cell death in multiple cancer types.

The BICR of radiographic imaging will enable clinical efficacy analyses of the first 50 patients with recurrent H3-K27M-mutant diffuse midline glioma who received single agent ONC201. These analyses will include overall response rate and key supportive endpoints, such as durability of response and other measures of clinical benefit. If favorable, these data may form the basis for an NDA submission seeking accelerated approval of ONC201 in the United States.

In addition, a Phase 1 clinical trial for ONC206, our second imipridone product candidate, and IND-enabling work for our third imipridone candidate, ONC212, remain ongoing.


Chimerix continues enrollment in the Phase 3 Dociparstat in AML with Standard Chemotherapy (DASH AML) study of DSTAT for the treatment of AML. The multicenter, randomized, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy and safety of DSTAT in combination with standard intensive induction and consolidation chemotherapy for the treatment of newly-diagnosed AML patients. Chimerix expects to unblind data following enrollment of the first 80 evaluable patients in this study to assess complete response rates and minimal residual disease rates between the study arm and the control arm. This analysis is expected to take place in the second half of 2022.

Expected 2021 Milestones

  • Negotiation of a smallpox procurement agreement for TEMBEXA
  • Completion of TEMBEXA drug product manufacturing to support potential shipments up to $100 million for U.S. national preparedness
  • Efficacy analysis by blinded independent central review of 50-subject registration cohort of ONC201 in recurrent H3 K27M-mutant glioma

Second Quarter 2021 Financial Results

Chimerix reported a net loss of $17.8 million, or $0.21 per basic and diluted share, for the second quarter of 2021. During the same period in 2020, Chimerix recorded a net loss of $10.0 million, or $0.16 per basic and diluted share.

Revenues for the second quarter of 2021 decreased to $0.4 million, compared to $1.4 million for the same period in 2020.

Research and development expenses increased to $13.8 million for the second quarter of 2021, compared to $8.6 million for the same period in 2020.

General and administrative expenses increased to $4.4 million for the second quarter of 2021, compared to $3.1 million for the same period in 2020.
Chimerix's balance sheet at June 30, 2021, included approximately $140 million of capital available to fund operations, $14.0 million in a note payable related to the Oncoceutics transaction and approximately 86.2 million outstanding shares of common stock.

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. In June 2021, the U.S. Food and Drug Administration granted approval of TEMBEXA for the treatment of smallpox as a medical countermeasure. The Company has two other advanced clinical-stage development programs, ONC201 and dociparstat sodium (DSTAT). ONC201 is currently in a registrational clinical program for recurrent H3 K27M-mutant glioma and an efficacy analysis by blinded independent central review is expected later in 2021. DSTAT is in development as a potential first-line therapy in acute myeloid leukemia.


TEMBEXA is an oral antiviral formulated as 100 mg tablets and 10 mg/mL oral suspension dosed once weekly for two weeks. TEMBEXA is indicated for the treatment of human smallpox disease caused by variola virus in adult and pediatric patients, including neonates. TEMBEXA is not indicated for the treatment of diseases other than human smallpox disease. The effectiveness of TEMBEXA for the treatment of smallpox disease has not been determined in humans because adequate and well-controlled field trials have not been feasible and inducing smallpox disease in humans to study the drug’s efficacy is not ethical. TEMBEXA efficacy may be reduced in immunocompromised patients based on studies in immune deficient animals.

TEMBEXA (brincidofovir) is a nucleotide analog lipid-conjugate designed to mimic a natural monoacyl phospholipid to achieve effective intracellular concentrations of the active antiviral metabolite, cidofovir diphosphate. Cidofovir diphosphate exerts its orthopoxvirus antiviral effects by acting as an alternate substrate inhibitor for viral DNA synthesis mediated by viral DNA polymerase.



An increased incidence of mortality was seen in TEMBEXA-treated subjects compared to placebo-treated subjects in a 24-week clinical trial when TEMBEXA was evaluated in another disease.


Elevations in Hepatic Transaminases and Bilirubin: May cause increases in serum transaminases (ALT or AST) and serum bilirubin. Monitor liver laboratory parameters before and during treatment.

Diarrhea and Other Gastrointestinal Adverse Events: Diarrhea and additional gastrointestinal adverse events including nausea, vomiting, and abdominal pain may occur. Monitor patients, provide supportive care, and if necessary, do not give the second and final dose of TEMBEXA.

Coadministration with Related Products: TEMBEXA should not be co-administered with intravenous cidofovir.

Carcinogenicity: TEMBEXA is considered a potential human carcinogen. Do not crush or divide TEMBEXA tablets and avoid direct contact with broken or crushed tablets or oral suspension.

Male Infertility: Based on testicular toxicity in animal studies, TEMBEXA may irreversibly impair fertility in individuals of reproductive potential.


Common adverse reactions (adverse events assessed as causally related by the investigator in ≥ 2% of subjects) experienced in the first 2 weeks of dosing with TEMBEXA were diarrhea, nausea, vomiting and abdominal pain.



Based on findings from animal reproduction studies, TEMBEXA may cause fetal harm when administered to pregnant individuals. Pregnancy testing should be performed before initiation of TEMBEXA in individuals of childbearing potential to inform risk. An alternative therapy should be used to treat smallpox during pregnancy, if feasible.
