DURHAM, N.C., March 02, 2023 (GLOBE NEWSWIRE) -- Chimerix (NASDAQ:CMRX), a biopharmaceutical company whose mission is to develop medicines that meaningfully improve and extend the lives of patients facing deadly diseases, today reported financial results for the fourth quarter and full-year ended December 31, 2022 and provided an operational update.

“We exited 2022 with a clear focus on our oncology pipeline and the initiation of the Phase 3 ACTION trial of ONC201 in patients with H3 K27M-mutant glioma. Patients with this deadly disease are in desperate need of therapeutic options and ONC201’s robust foundation of data underscores its potential as a highly differentiated asset. Following the monetization of TEMBEXA, we have a strong balance sheet to fully fund Chimerix into 2027, including through potential approval of ONC201. Recent independent analyses reported overall survival advantage in patients treated with ONC201, which has further reinforced our confidence in the ACTION trial and the commercial opportunity for ONC201,” said Mike Sherman, Chief Executive Officer of Chimerix.

“As we look to 2023, we are making tremendous progress and continuing our strong execution to advance ONC201 towards regulatory approval. The ACTION trial is enrolling with sites active in the U.S. and internationally, and we remain on track for our first data readout in early 2025 with final data readout expected in 2026. We continue to evaluate emerging data from our earlier pipeline, including ONC206, which recently demonstrated a radiographic tumor response in its dose escalation study,” continued Mr. Sherman.

“The Pacific Pediatric Neuro-oncology Consortium has been pleased to take a leadership role in the clinical development of ONC206,” said Sabine Mueller, MD, PhD, MAS, Professor of Neurology, Neurosurgery and Pediatrics, University of California San Francisco (UCSF) and clinical lead of the Diffuse Midline Glioma Center in Zurich Switzerland. “We are very excited about the potential for ONC206 to treat brain cancers more broadly, beyond those with the H3K27M-mutation. To observe a monotherapy response in a recurrent glioblastoma patient without the H3K27M-mutation is quite exciting. The fact that this occurred with a dose level at the low end of the range has added to our enthusiasm as we continue to dose escalate.”

ONC201 for Treatment of H3 K27M-Mutant Diffuse Glioma

In November 2022, Chimerix initiated the Phase 3 ACTION study, a randomized, double-blind, placebo-controlled, multicenter international study of ONC201 in newly diagnosed diffuse glioma patients whose tumor harbors an H3 K27M-mutation. Treatment with ONC201 will begin shortly after completion of radiation therapy. The study is designed to enroll 450 patients randomized 1:1:1 to receive ONC201 at one of two dosing frequencies or placebo. Participants will be randomized to receive 625mg of ONC201 once per week (the Phase 2 dosing regimen), 625mg twice per week on two consecutive days or placebo. The dose will be scaled by body weight for pediatric patients. Overall survival (OS) will be assessed for efficacy at three alpha-allocated timepoints: two interim assessments by the Independent Data Monitoring Committee (IDMC) at 164 events and 246 events, respectively, and a final assessment at 327 events. The final Progression Free Survival analysis will be performed after 286 events, with progression assessed using RANO HGG criteria by blinded independent central review (BICR).

Ongoing Development of ONC206

ONC206 is a second generation imipridone that has demonstrated anti-cancer activity in pre-clinical models of various central nervous system (CNS) tumors and other malignancies. ONC206 is a ClpP agonist and DRD2 antagonist with enhanced in vitro potency relative to ONC201. ONC206 is currently being evaluated in Phase 1 dose escalation clinical trials for adults with recurrent primary central nervous system tumors at the National Institutes of Health (NIH) and in pediatric CNS tumors with the Pacific Pediatric Neuro-Oncology Consortium (PNOC). Preclinical and early clinical observations in initial low dose cohorts suggest that ONC206 may be effective for CNS tumors beyond those that harbor the H3 K27M mutation addressed by ONC201.

An investigator- assessed response in a recurrent glioblastoma patient without the H3K27M-mutation who received monotherapy ONC206 has emerged during dose escalation in the PNOC study.

The unmet need in glioblastoma is extraordinarily high with over 25,000 newly diagnosed patients in the United States and Europe annually. Dose escalation will continue, and results are expected to be reported at a future scientific conference.

Fourth Quarter 2022 Financial Results

Chimerix's balance sheet at December 31, 2022 included $266.0 million of capital available to fund operations, no debt, and approximately 88.1 million outstanding shares of common stock.

Chimerix reported a net loss of $21.0 million, or $0.24 per basic and diluted share, for the fourth quarter of 2022, compared to a net loss of $39.5 million, or $0.45 per basic and diluted share for the fourth quarter of 2021.

Research and development expenses decreased to $19.3 million for the three-month period ended December 31, 2022, compared to $34.3 million for the same period in 2021.

General and administrative expenses increased to $5.3 million for the fourth quarter of 2022, compared to $5.2 million for the same period in 2021.

Full Year 2022 Financial Results

Chimerix reported a net income of $172.2 million, or $1.97 per basic and $1.94 per diluted share, for the year ended December 31, 2022. For the year ended December 31, 2021, Chimerix recorded a net loss of $173.2 million, or $2.04 per basic and diluted share. The increase was primarily driven by the sale of TEMBEXA to Emergent BioSolutions.

Revenues for 2022 increased to $33.8 million, compared to $2.0 million in 2021.

Research and development expenses decreased to $71.6 million for the year ended December 31, 2022, compared to $73.8 million for the year ended December 31, 2021.

General and administrative expenses increased to $22.1 million for the year ended December 31, 2022, compared to $18.7 million for the year ended December 31, 2021.
