Emergent BioSolutions Inc. announced that it has completed its acquisition of exclusive worldwide rights to TEMBEXA (brincidofovir), the first oral antiviral approved by the U.S. Food and Drug Administration (FDA) for all age groups for the treatment of smallpox, from Chimerix. TEMBEXA was approved in June 2021 and is indicated for the treatment of human smallpox disease in adult and pediatric patients, including neonates.
The completion of the acquisition follows the satisfaction or waiver by the parties, as applicable, of all closing conditions, including expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (HSR Act), as amended, and receipt of consent from the Biomedical Advanced Research and Development Authority (BARDA), part of the Administration for Strategic Preparedness and Response within the U.S. Department of Health and Human Services, for a sub-contract agreement between Chimerix and Emergent.
“The addition of TEMBEXA to our smallpox medical countermeasure franchise, which consists of our smallpox vaccine and therapeutic for smallpox vaccine complications, creates a more comprehensive offering to combat this deadly public health threat,” said Paul Williams, SVP government/MCM business at Emergent. “We look forward to supporting the U.S. government’s smallpox preparedness strategy on a broader scale by executing on this BARDA contract.”
The 10-year contract (75A50122C00047), valued at up to $680 million, to supply up to 1.7 million treatment courses of tablet and suspension formulations of TEMBEXA to the U.S. government, was awarded to Chimerix on August 29, 2022. The contract includes an initial product procurement valued at approximately $115 million, with optional future procurement, valued at up to approximately $551 million, exercisable at the sole discretion of BARDA. In addition to product procurement, the contract includes reimbursed post marketing activities of approximately $12 million.
