"Bringing Chimerix into Jazz adds a novel medicine to our oncology portfolio and advances our efforts to address unmet patient needs," said Bruce Cozadd, chairman and chief executive officer of Jazz. "Dordaviprone has the potential to become the first and only FDA-approved therapy for patients with H3 K27M-mutant diffuse glioma and offers a promising near-term commercial opportunity, if approved. We are excited to welcome Chimerix’s talented team as we collectively continue to advance dordaviprone, leveraging our development and commercial capabilities to deliver this therapy to patients as soon as the second half of this year."

The addition of dordaviprone, a novel first-in-class small molecule treatment in development for H3 K27M-mutant diffuse glioma, further diversifies and adds near-term commercial opportunity to Jazz’s oncology pipeline. Dordaviprone is currently under Priority Review by the U.S. Food and Drug Administration (FDA), with a Prescription Drug User Fee Act (PDUFA) action date set for August 18, 2025. If approved in the U.S., the therapy may be eligible for a Rare Pediatric Disease Priority Review Voucher (PRV). Dordaviprone is also being studied in the ongoing Phase 3 ACTION trial to evaluate its use in newly diagnosed, non-recurrent H3 K27M-mutant diffuse glioma patients following radiation treatment, potentially extending its use into the first-line setting.

About Dordaviprone

Dordaviprone (ONC201) is a novel first-in-class small molecule imipridone that selectively targets the mitochondrial protease ClpP and 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.
