Emergent also plans to assume responsibility for a multi-year contract with the Biomedical Advanced Research and Development Authority (BARDA), valued at up to approximately $130 million, to supply the product to the U.S. Strategic National Stockpile (SNS).

The addition of this critical countermeasure further strengthens our leadership position in this market and expands our franchise of vaccines and therapeutics addressing Category A bioterrorism threats. We look forward to establishing raxibacumab as an anchor FDA-approved product for our newly-expanded Bayview manufacturing facility in Baltimore, Maryland. As we focus on providing preparedness solutions to public health threats, we will continue to actively pursue additional acquisition opportunities that leverage our core competencies and drive growth.”

Emergent expects to fulfill the deliveries of raxibacumab to the SNS by the end of 2019 under the current BARDA contract, subject to the availability of funding, and expects to negotiate a follow-on contract with the U.S. government to ensure the uninterrupted supply of this critical medical countermeasure to the SNS. Under the terms of the acquisition agreements, Emergent expects to purchase product from GSK to enable completion of deliveries to the SNS under the existing BARDA procurement contract.
