• Upon Urging of HHS, Emergent Plans to Submit Response to BAA by the End of This Year
• BioThrax^® Remains Sole Anthrax Vaccine Available for USG Procurement for at Least the Next 8 Years

ROCKVILLE, Md.--(BUSINESS WIRE)--Dec. 7, 2009-- Emergent BioSolutions Inc. (NYSE:EBS) announced today that it has been advised by the Office of the Biomedical Advanced Research and Development Authority (BARDA) that the Request for Proposal (RFP) for the procurement of rPA vaccines has been cancelled in favor of a Broad Agency Announcement (BAA) for rPA vaccine development. According to BARDA officials, BARDA took this action after a technical evaluation panel determined that none of the vaccine developers submitting proposals could meet the Project BioShield statutory requirement of having a product ready for licensure within 8 years.

Simultaneously, BARDA issued an amendment to BAA 09-34 to enable companies to submit proposals to obtain development funding for rPA vaccine candidates. The due date for all proposals is February 1, 2010. During a meeting with company officials today, BARDA strongly encouraged Emergent to submit a proposal to this BAA. Emergent intends to submit its proposal by the end of this year.

This decision by BARDA has no impact on the company’s $400 million procurement contract with the Centers for Disease Control and Prevention (CDC) for the manufacture and delivery of 14.5 million doses of BioThrax^® into the Strategic National Stockpile (SNS). The company is currently delivering BioThrax under this contract and expects to complete deliveries by September 2011. BioThrax is the only vaccine licensed by the FDA for the prevention of anthrax disease.

“With this action, BioThrax remains a critical and long-term countermeasure for the US government,” said Fuad El-Hibri, chairman and chief executive officer of Emergent BioSolutions. “In addition, based upon encouragement by the USG, we believe our rPA vaccine is well-positioned to obtain a development contract under this BAA. Our anthrax franchise solidifies Emergent as a leader in the development and supply of anthrax medical countermeasures.”

Emergent has recently resumed BioThrax scale-up activities within its new 50,000 sq. ft. state-of-the-art manufacturing facility in Lansing. In addition, BARDA and Emergent are in discussions for a separate contract under which BARDA would fund scale-up and related activities to obtain FDA licensure for large-scale production of BioThrax in this new facility. This new facility is designed as a campaignable, multi-product facility capable of producing up to 30 million doses of BioThrax per annum. With the addition of a second train, the capacity of the facility could be doubled to up to 60 million doses per annum.

“This is an exciting development because it positions BioThrax as the sole anthrax vaccine for USG procurement for at least the next eight years,” said Daniel J. Abdun-Nabi, president and chief operating officer, Emergent BioSolutions. “We believe that BioThrax will remain a premier product based on its recent enhancements, such as four-year dating, a reduced vaccination schedule and intramuscular route of administration, together with the potential for a further reduction in the vaccination schedule to a 3-dose primary series with a 3-year boost. BioThrax continues to be the product of choice for the USG and other customers seeking to address the anthrax threat.”
