Chimerix Prepares to Submit Dordaviprone for FDA Approval

Chimerix's Journey Towards FDA Approval for Dordaviprone

Chimerix, a pioneering biopharmaceutical company, is set to embark on a crucial phase in its quest to bring dordaviprone to patients suffering from recurrent H3 K27M-mutant diffuse glioma. The company aims to submit a comprehensive New Drug Application (NDA) to the U.S. FDA before the year concludes. This bold move follows extensive discussions with the FDA, and it underscores Chimerix’s commitment to improving the lives of patients grappling with one of the most aggressive forms of brain cancer.

The Significance of Dordaviprone

Dordaviprone holds the potential to reshape the treatment landscape for patients diagnosed with this lethal disease. Mike Andriole, the Chief Executive Officer of Chimerix, expressed optimism about the potential approval, stating that it could transform the current limited treatment options available for affected individuals. In anticipation of a favorable outcome, the company has fortified its commercial leadership team to ensure readiness for a U.S. launch as early as the third quarter of 2025.

Commitment to Patients

With over 2,000 patients in the U.S. diagnosed annually with H3 K27M-mutant gliomas, the urgency behind Chimerix’s submission is palpable. Allen Melemed, M.D., Chimerix’s Chief Medical Officer, highlighted the heartfelt significance of this initiative, particularly for pediatric patients and young adults who face dire prognosis. The team is confident that the data compiled thus far will substantiate its case for accelerated approval, addressing a critical unmet medical need.

Key Milestones and Data Support

The NDA submission will encapsulate several key milestones that signal the promising potential of dordaviprone:

• Significant progress in the Phase 3 ACTION study, showcasing robust patient enrollment.
• Insights from the Phase 2 study indicating an objective response rate of 28%, with favorable conditions outlined by the Response Assessment in Neuro-Oncology 2.0 (RANO 2.0) criteria.
• Compelling supporting evidence from an extensive safety database that advocates for dordaviprone’s favorable benefit/risk profile.
• A diverse array of clinical pharmacology studies and chemistry, manufacturing, and controls (CMC) assessments.

Chimerix is also advocating for Priority Review designation on its NDA, which, if granted, would facilitate a streamlined six-month review process by the FDA, targeting a potential Prescription Drug User Fee Act (PDUFA) action date in the latter half of 2025.

Rare Pediatric Disease Designation

Dordaviprone has already achieved Rare Pediatric Disease Designation, allowing Chimerix to apply for a Rare Pediatric Disease Priority Review Voucher upon submission of the NDA. This adds a promising layer to Chimerix’s strategy as they navigate the path toward regulatory approval.

Investors and Stakeholders

To keep investors and stakeholders informed, Chimerix is set to host a conference call where they will discuss the upcoming NDA submission and its implications. This call will be accessible via dial-in and will include a comprehensive overview of Chimerix's plans moving forward.
