Jazz Pharmaceuticals (NASDAQ: JAZZ) has announced its acquisition of Chimerix (NASDAQ: CMRX) for approximately $935 million in an all-cash transaction. The deal, expected to close in the second quarter of 2025, will bolster Jazz’s oncology portfolio by adding Chimerix’s lead asset, dordaviprone, a promising treatment for rare brain tumors.
Dordaviprone is a novel small-molecule therapy in development for H3 K27M-mutant diffuse glioma, an aggressive brain tumor that primarily affects children and young adults. Currently, there are no FDA-approved treatments specifically for this patient group, with radiation being the standard approach. The drug has been granted Priority Review by the FDA, with a target decision date set for August 18, 2025. If approved, dordaviprone could become a breakthrough treatment and may qualify for a Rare Pediatric Disease Priority Review Voucher (PRV).
Jazz Pharmaceuticals’ Chairman and CEO, Bruce Cozadd, emphasized the strategic importance of the acquisition. “Dordaviprone has the potential to become a standard of care for a rare oncology disease with no current FDA-approved treatments,” said Cozadd. “This deal reinforces our commitment to patients with rare diseases and adds a near-term commercial opportunity to our pipeline.”
Chimerix CEO Mike Andriole echoed this sentiment, highlighting the benefits of Jazz’s global commercial scale in expanding access to dordaviprone. “This agreement enables us to reach more patients globally while delivering significant value to our shareholders,” he stated.
Dordaviprone is currently being studied in a Phase 3 ACTION trial, evaluating its use in newly diagnosed, non-recurrent H3 K27M-mutant diffuse glioma patients following radiation. If successful, this could expand its use beyond recurrent cases.
The acquisition price of $8.55 per share represents a 72% premium over Chimerix’s closing stock price on March 4, 2025. Jazz will finance the transaction using its existing cash and investments.
The deal strengthens Jazz’s position in rare oncology and provides a potential long-term revenue stream, with patent protection for dordaviprone extending to 2037. If approved, the drug could see a rapid commercial launch in the U.S. in the second half of 2025.
Jazz expects to leverage its development and commercialization expertise to execute a strong launch strategy, positioning dordaviprone as a new standard of care for H3 K27M-mutant diffuse glioma. The acquisition is subject to customary closing conditions, including regulatory approvals and the tendering of a majority of Chimerix’s shares.
With this move, Jazz Pharmaceuticals reinforces its commitment to oncology innovation and its mission to address significant unmet medical needs. If the FDA grants approval, dordaviprone could be a game-changer for brain tumor treatment, offering hope to patients with limited options.
