DURHAM, N.C., Nov. 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 third quarter ended September 30, 2023 and provided an operational update.

“The third quarter was marked by strong progress across our first-in-class imipridone pipeline, including continued enrollment in our global Phase 3 ACTION study of ONC201 for the treatment of H3 K27M-mutant diffuse glioma,” said Mike Andriole, Chief Executive Officer of Chimerix. “We continue to see strong interest in the ACTION study globally supported by a robust publication strategy, including the recently published front-line treatment and mechanistic data in the peer-reviewed journal Cancer Discovery. These data demonstrated a statistically significant increase in median overall survival (mOS) versus historical controls in a patient population with very few treatment options. As enrollment in the ACTION study continues to progress, we are also working extensively on our second-generation compound, ONC206, to identify biomarkers in patients most likely to respond in future primary efficacy studies. These early data indicate such studies may include both Central Nervous System (CNS) tumors as well as solid tumors outside of the CNS. Finally, we were delighted to join the neuro-oncology community at the European Association of Neuro-Oncology (EANO) Annual Meeting in Rotterdam last month and look forward to the upcoming Society for Neuro-Oncology (SNO) Annual Meeting in Vancouver where multiple oral presentations will highlight a series of preclinical and clinical studies of ONC201 as both monotherapy and as a potential backbone in combinatorial diffuse midline glioma (DMG) treatment settings.”

ONC201 for Treatment of H3 K27M-Mutant Diffuse Glioma

The Phase 3 ACTION trial is currently enrolling patients at 113 sites in 12 countries and remains on track to report first interim overall survival data in early 2025.

The ACTION trial is enrolling patients shortly after front-line radiation therapy. The study is designed to enroll 450 patients randomized 1:1:1 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 patients <52.5kg.

In August 2023, a Cancer Discovery publication reported promising survival outcomes for 71 H3 K27M-DMG patients treated with ONC201. In addition, ONC201 reversed a molecular signature of the H3 K27M mutation in patient’s tumor samples.


ONC206 is a second generation ClpP agonist and DRD2 antagonist that has demonstrated monotherapy anti-cancer activity in pre-clinical models in primary CNS tumors and solid tumors outside of the CNS. Phase I dose escalation trials continue at the National Institutes of Health (NIH) and the Pacific Pediatric Neuro-Oncology Consortium (PNOC) in adult and pediatric CNS tumor patients, respectively. To date, ONC206 has been generally well tolerated with no dose limiting toxicities. The dose escalation trials have completed the once weekly dosing schedules. The study is currently dosing at more frequent dose schedules that are expected to increase the duration of therapeutic exposure.

Third Quarter 2023 Financial Results

Chimerix reported a net loss of $24.0 million, or $0.27 per basic and diluted share, for the third quarter of 2023. During the same period in 2022, Chimerix recorded net income of $241.4 million, or $2.75 per basic and diluted share.

Research and development expenses increased to $17.4 million for the third quarter of 2023, compared to $15.3 million for the same period in 2022.

General and administrative expenses increased to $9.3 million for the third quarter of 2023, compared to $5.3 million for the same period in 2022. This increase is in connection with the retirement of the CEO and transition to Chairman which resulted in a one-time non-cash expense being recognized related to historical equity grants, the vesting of which remain contingent on future service in the new role.

Chimerix’s balance sheet at September 30, 2023 included $217 million of capital available to fund operations, approximately 88.9 million outstanding shares of common stock and no outstanding debt. Chimerix expects to end the year with over $200 million in cash and cash equivalents which is expected to be sufficient to fund operations through final ACTION study data expected in 2026.
