Emergent BioSolutions Inc. (NYSE:EBS) announced today that the Biomedical Advanced Research and Development Authority (BARDA) has exercised its first contract option valued at $261 million to procure doses of AV7909 (anthrax vaccine adsorbed with adjuvant) for delivery into the Strategic National Stockpile (SNS) over 12 months. This contract option was exercised under the company’s 2016 development and procurement contract with BARDA, valued at up to $1.5 billion, that includes a five-year base period of performance to develop AV7909 for post-exposure prophylaxis of anthrax disease and to deliver an initial three million doses to the SNS, as well as contract options for procurement of up to an additional 50 million doses. This exercise of the contract option through a modification is the first such option for procurement of doses to follow the initial deliveries of doses under the base contract.
