DURHAM, N.C., Nov. 07, 2024 (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 third quarter ended September 30, 2024 and provided an operational update.

“We have sustained execution of the Phase 3 ACTION study and continue to be encouraged by the safety profile of dordaviprone following the Independent Data Monitoring Committee’s (IDMC) preplanned safety review which recommended continuing study conduct as-is, including at the more intense twice per week dose. Additionally, the Therapeutic Goods Administration (TGA) has granted orphan drug designation to dordaviprone, and we have alignment to file a New Drug Application (NDA) for Provisional Approval in Australia which we expect to occur in the coming months,” said Mike Andriole, Chief Executive Officer of Chimerix. “As we complete the dordaviprone NDA and look toward the balance of the year, we also expect to complete enrollment in a Phase 1 dose escalation study of ONC206 as we consider future development scenarios for this program.”

“In addition, we were delighted to announce the promotion of Dr. Josh Allen to the role of Chief Scientific Officer this quarter. Josh has been instrumental in the discovery and development of the imipridone class of compounds and expect his broad expertise in cancer biology and strong business acumen will underpin Chimerix early phase development for years to come,” 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 dopamine receptor D2 (DRD2). Dordaviprone's unique mechanism of action includes alterations of key epigenetic modifications such as reversal of H3 K27me3-loss which is the hallmark of H3 K27M-mutant gliomas.

Dordaviprone is being evaluated in the Phase 3 ACTION trial that is currently enrolling H3 K27M-mutant diffuse glioma patients at over 145 sites in 15 countries. Chimerix expects interim OS data in the third quarter of 2025. For more information on the ACTION trial, please visit www.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. The second step, the Provisional Determination Application, was approved during the third quarter 2024, as was the application for Orphan Drug Designation in Australia. The final step is the NDA submission for Provisional Registration which is expected to occur in the coming months with potential commercial availability as soon as year-end 2025.

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 anti-cancer activity in vivo 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 80 pediatric and adult patients with unselected CNS tumors, 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 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.

Corporate

In September 2024, Chimerix promoted Joshua E. Allen, PhD, to the role of Chief Scientific Officer after previously serving as Chief Technology Officer. Dr. Allen co-discovered the anti-cancer activity of ONC201 and co-invented the imipridone class of compounds. He has continuously advanced the research and development of dordaviprone from academic discovery to its registration program, along with the creation and clinical introduction of biologically distinct derivatives. He received his Ph.D. in Biochemistry and Molecular Biophysics from the University of Pennsylvania. Several research publications, patents, grants, and awards reflect his scientific and entrepreneurial efforts in oncology, including recognition on the Forbes 30 under 30 list. Prior to joining Chimerix, Dr. Allen served as Chief Scientific Officer at Oncoceutics.

Third Quarter 2024 Financial Results

Chimerix reported a net loss of $22.9 million, or $0.26 per basic and diluted share, for the third quarter of 2024. During the same period in 2023, Chimerix recorded a net loss of $24.0 million, or $0.27 per basic and diluted share.

Research and development expenses increased to $19.6 million for the third quarter of 2024 compared to $17.4 million for the same period in 2023.

General and administrative expenses decreased to $5.2 million for the third quarter of 2024 compared to $9.3 million for the same period in 2023. This decrease is due to a one-time non-cash expense related to historical equity grants recognized during the 2023 period.

Chimerix’s balance sheet at September 30, 2024 included $152.4 million of capital available to fund operations, approximately 89.9 million outstanding shares of common stock and no outstanding debt.
