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 confirms that the Company has submitted a New Drug Application (NDA) with the U.S. Food and Drug Administration (FDA) seeking accelerated approval for dordaviprone as a treatment for patients with recurrent H3 K27M-mutant diffuse glioma in the United States.

“This NDA submission marks a pivotal moment for Chimerix in our mission to bring this potentially life-altering drug to patients diagnosed with recurrent H3 K27M-mutant diffuse glioma,” said Mike Andriole, Chief Executive Officer of Chimerix. “With this submission, we now turn our attention to preparing for potential commercial launch in the U.S. next year. To maximize availability and access of dordaviprone at launch, we have enhanced our commercial capabilities across multiple functions including market access, distribution, reimbursement, patient services, marketing and commercial operations, all supported by a robust manufacturing and quality management system.”

“We also entered into a credit facility of up to $30 million with Silicon Valley Bank providing access to additional capital during this upcoming investment cycle and helping ensure dordaviprone availability to as many patients as possible, as quickly as possible, if approved. We are grateful to our partners at Silicon Valley Bank for their long-term support of Chimerix. This credit facility provides valuable financial optionality leading up to, and through, a potential U.S. launch of dordaviprone,” said Michelle LaSpaluto, Chief Financial Officer of Chimerix.

Chimerix has requested Priority Review for the NDA. If granted, the resulting six-month FDA review period is expected to result in a potential Prescription Drug User Fee Act (PDUFA) action date in the third quarter of 2025. Dordaviprone has received Rare Pediatric Disease Designation for H3 K27M-mutant glioma and has applied for a Rare Pediatric Disease PRV as part of this NDA submission.

In addition, the Company announced it entered into an amended and restated loan and security agreement for up to $30 million with Silicon Valley Bank (SVB), a division of First-Citizens Bank. Under the terms of the agreement, Chimerix may draw down up to $20.0 million through the period ending February 28, 2026. An additional $10 million may also be made available upon the Company’s request through February 28, 2027, subject to SVB’s approval. No draws have been made on this facility to date.
