CMRX Chimerix Inc

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, 2024 and provided an operational update.

“We continued our strong execution of the Phase 3 ACTION study and expect the first interim overall survival (OS) data in the third quarter of 2025. As we approach this important milestone, we continue to strengthen our U.S. launch capabilities and readiness,” said Mike Andriole, Chief Executive Officer of Chimerix. “Additionally, we are making great strides advancing ONC206 through the remaining dose cohorts in two Phase 1 trials, which recently achieved dosing within an expected therapeutic range. As we escalate and intensify the dose within this range, we are encouraged by ongoing pharmacokinetic (PK) data that is in line with modeled expectations for delivering dose proportionate exposures for extended durations. Importantly, these exposures have not been associated with dose limiting toxicities thus far. We expect to complete enrollment in the ONC206 dose escalation trials by the end of this year.”

“We have also made progress expanding the global reach for dordaviprone with the recent filing of a Provisional Determination application in Australia. This marks the second of three steps to potential Provisional Approval. Our team continues to be driven by the urgent need of patients focusing on indications where the unmet medical need remains frustratingly high. We will continue to drive our pipeline forward in order to accelerate access to patients in need of new treatment alternatives,” added Mr. Andriole.

Dordaviprone (ONC201)

Dordaviprone, a first-in-class imipridone, has the potential to be the first treatment approved for H3 K27M-mutant diffuse glioma. It is an oral small molecule that crosses the blood-brain barrier and selectively binds to the mitochondrial protease ClpP and the G-protein-coupled dopamine receptor D2 (DRD2).  Dordaviprone's unique mechanism of action includes alterations of key epigenetic modifications such as reversal of H3 K27me3-loss (H3 K27 trimethyl loss), which is the hallmark of H3 K27M-mutant gliomas.

The Company estimates that approximately 2,000 patients with diffuse glioma harbor the H3 K27M mutation in the United States and approximately 5,000 patients in the top seven markets globally. With no approved therapies specific to this patient population, the standard of care following upfront radiotherapy remains palliative in nature.

Dordaviprone is being evaluated in the Phase 3 ACTION trial that is currently enrolling H3 K27M-mutant diffuse glioma patients at over 140 sites in 13 countries. Chimerix expects interim OS data in the third quarter of 2025. For more information on the ACTION trial, please visit clinicaltrials.gov

Earlier this year, Chimerix initiated the evaluation process for dordaviprone to be considered for Provisional Registration in Australia. The Provisional Registration process is a three-step process which begins with a Pre-Submission Meeting evaluating current data, as well as other program features, including the status of pivotal studies. Chimerix recently initiated the second of three steps in the process, the filing of a Provisional Determination application. Should the TGA approve the Provisional Determination application, the final step is to apply for Provisional Registration. Should Chimerix proceed to the Provisional Registration step, it is expected that a filing could occur as early as year-end 2024 with possible commercial availability in 2026.

ONC206

The imipridone ONC206 is a second generation ClpP agonist and DRD2 antagonist which also crosses the blood-brain barrier and is 10x more potent in vitro than dordaviprone. It has demonstrated monotherapy in vivo anti-cancer activity in central nervous system (CNS) tumor models, as well as in vivo solid tumors models outside of the CNS. The two Phase 1 dose escalation trials conducted in partnership with the Pacific Pediatric Neuro-Oncology Consortium (PNOC) and the National Institutes of Health (NIH) have enrolled over 75 pediatric and adult patients with unselected CNS tumors. The dose escalation studies have reached dose level 10 (of 11 planned levels) at 150mg twice per day for three consecutive days, with no dose limiting toxicity observed to date.

The safety profile of ONC206 has been consistent across both pediatric and adult populations, with the majority of treatment-related adverse events being mild to moderate, including fatigue, lymphocyte count decrease and vomiting. No significant change in the overall safety profile has been reported to date as dosing has escalated and intensified in frequency from once per week to twice per day on three consecutive days per week. Completion of enrollment in the remaining two planned dose escalation cohorts is expected to occur in 2024.

Assessment of objective responses in patients where a monotherapy treatment effect can be reliably evaluated is ongoing in dose cohorts at or above target exposure thresholds. The company expects to assess any objective responses in the first half of 2025, allowing sufficient time for response onset and confirmation in current and future dose cohorts.

Additionally, ONC206 nonclinical studies remain ongoing to identify candidate oncology indications and biomarkers to inform future development plans.
