DURHAM, N.C., Aug. 03, 2023 (GLOBE NEWSWIRE) -- Chimerix (NASDAQ:CMRX), a biopharmaceutical company whose mission it is to develop medicines that meaningfully improve and extend the lives of patients facing deadly diseases, today reported financial results for the second quarter ended June 30, 2023 and provided an operational update.

"I am thrilled to begin leading the organization during such a pivotal time in Chimerix’s history and in the field of neuro-oncology, where several genetically defined programs have advanced the field recently. During the second quarter, our team has been laser focused on site activation and enrollment of the Phase 3 ACTION study which now includes 77 sites enrolling patients across 11 countries and an enrollment rate that remains on track for the first interim overall survival analysis in early 2025. We are incredibly grateful to the neuro-oncology community which is eagerly supporting the ACTION study in order to advance the treatment for patients with this cancer. H3 K27M-mutant glioma is estimated to occur in 5,000 people annually in the major global markets,” said Mike Andriole, Chief Executive Officer of Chimerix.

“Furthermore, dose escalation for our second-generation compound, ONC206, continues and completion is expected in the first half of 2024. There have been no dose limiting toxicities identified during dose escalation thus far and we are now exploring a more intense dose and schedule with the goal of identifying additional signals of activity,” added Mr. Andriole.  

ONC201 for Treatment of H3 K27M-Mutant Diffuse Glioma

The Phase 3 ACTION trial is currently enrolling patients at 77 sites in 11 countries and remains on track to report interim data in early 2025.

The ACTION trial is enrolling patients shortly after they have completed standard of care front-line 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 patients <52.5kg. 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 (PFS) analysis will be performed after 286 events, with progression assessed using RANO HGG criteria by blinded independent central review (BICR). Secondary endpoints include corticosteroid response, performance status response, change from baseline in quality of life (QoL) assessments and change from baseline in neurologic function as assessed by the Neurologic Assessment in Neuro-Oncology (NANO) scale.


ONC206 is a second generation DRD2 antagonist and ClpP agonist that has demonstrated monotherapy anti-cancer activity in pre-clinical models. Phase I dose escalation trials continue at the National Institutes of Health (NIH) and the Pacific Pediatric Neuro-Oncology Consortium (PNOC). In March 2023, the Company reported an investigator-assessed response in a patient with recurrent glioblastoma without the H3K27M-mutation. The patient has continued to respond and remains on treatment, receiving increasing doses as part of the dose escalation. To date, ONC206 is generally well tolerated with a similar safety profile in adults and pediatrics. No dose limiting toxicities have been identified to date. The dose escalation trials are transitioning to intensify dosing from a once weekly dosing to a more frequent dose schedule to increase the duration of therapeutic exposure.
