The company’s submission provides the U.S. Government with the critical option to select a domestic source to meet planned procurement of 25 million doses of rPA vaccine.

Emergent BioSolutions Inc. (NYSE: EBS) announced today that it has submitted a proposal in response to a request for proposal (RFP) issued by the U.S. Department of Health and Human Services (HHS) for a recombinant protective antigen anthrax vaccine (rPA). Emergent’s rPA vaccine candidate, which has completed one Phase II clinical trial, is a reformulated and more stable form of the rPA 102 vaccine originally developed at USAMRIID and is well positioned to be a leading candidate for an award under this RFP.

This RFP is designed to meet the government’s stated goal to procure 25 million doses of an rPA anthrax vaccine for the Strategic National Stockpile (SNS). This contract would be in addition to the $448 million three-year contract awarded to Emergent in 2007 that includes the supply of 18.75M doses of its FDA licensed anthrax vaccine BioThrax to the SNS. In the event that Emergent receives an award under the rPA RFP, doses of rPA procured by HHS would be in addition to the 18.75 million doses of BioThrax being procured by HHS pursuant to the three-year contract. HHS has indicated that any awards under the rPA RFP would be granted at the end of 2008, at the earliest.

“We are very pleased with our submission in response to this RFP and we are confident that our rPA 102 vaccine is a leading candidate to be selected as an advanced rPA anthrax vaccine. Our company is proud of our proven track record of delivering critical biodefense countermeasures to the U.S. government and we believe our reputation as the premiere domestic biodefense supplier, coupled with our development and manufacturing expertise, uniquely situates Emergent to meet HHS’s stated commitment to procure 25 million doses of a recombinant anthrax vaccine for the Strategic National Stockpile,” said Fuad El-Hibri, chairman and chief executive officer of Emergent BioSolutions.

“Considerable effort and resource have been directed toward improving the stability of the rPA 102 vaccine. Analytical testing as well as animal immunogenicity and efficacy studies indicate the stability of our recombinant protective antigen vaccine candidate has been significantly improved. We are confident that the new, enhanced vaccine formulation will address any stability concerns HHS may have had in the past. The current formulation, we believe, will meet and most likely exceed BARDA stability requirements for an rPA vaccine,” said Dr. James Jackson, senior vice president and chief scientific officer of Emergent BioSolutions.

The company intends to manufacture this rPA anthrax vaccine, as well as BioThrax, in its recently constructed, large-scale manufacturing facility at its Lansing campus. The continued development of this rPA vaccine candidate further solidifies Emergent’s well established franchise of anthrax countermeasures, which now includes:

BioThrax® (Anthrax Vaccine Adsorbed) is the only FDA-approved vaccine to prevent the infection of anthrax. Nearly 2.0 million men and women of the United States military have received the vaccine, and HHS has procured more than 28 million doses of BioThrax for the SNS;

rPA 102, a recombinant anthrax vaccine candidate, which is composed of a purified protein with an alum adjuvant and is designed to induce antibodies that neutralize anthrax toxins;

AVP-21D9, a human monoclonal antibody product candidate being developed as an intravenous post-exposure treatment for patients who present symptoms of anthrax disease; and

AIG, a polyclonal anthrax immune globulin product candidate being developed as an intravenous post-exposure treatment for patients who present symptoms of anthrax disease, is derived from human plasma from individuals who have been vaccinated with BioThrax.

About rPA 102
The vaccine candidate, rPA 102, is based on a recombinant form of the protective antigen protein. This vaccine contains a purified protein (rPA) formulated with an alum adjuvant and is designed to induce antibodies that neutralize anthrax toxins. The vaccine candidate does not cause anthrax infection and is based on the pioneering work of the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID). rPA 102 has been the subject of two research and development grants totaling approximately $100 million from the National Institute for Allergy and Infectious Diseases (NIAID).

Acquisition positions Emergent to offer the U.S. Government a domestic source for an advanced anthrax vaccine candidate to meet planned procurement of 25 million doses of rPA vaccine.

Emergent BioSolutions Inc. (NYSE: EBS) announced today that it has completed the acquisition of all assets and rights related to a recombinant protective antigen (rPA) anthrax vaccine product candidate and related technology from VaxGen, Inc. Recent improvements to the rPA vaccine, specifically related to stability, suggests that it is well positioned to be a leading candidate for an award under a request for proposal (RFP) recently issued by the U.S. Department of Health and Human Services (HHS). The vaccine candidate has completed one Phase 2 clinical study. This RFP is designed to meet the government’s stated goal to procure 25 million doses of an rPA anthrax vaccine for the Strategic National Stockpile (SNS). HHS has indicated that any awards under this RFP are scheduled to be granted in late 2008.

The acquisition of this rPA vaccine candidate, and the pending RFP, have no effect on Emergent’s $448 million contract with HHS for the delivery of 18.75 million doses of BioThrax® (Anthrax Vaccine Adsorbed), the only FDA approved vaccine for the prevention of anthrax disease, into the SNS. Emergent continues to manufacture and deliver doses of BioThrax in accordance with this multi-year agreement.

The company intends to manufacture this new rPA anthrax vaccine, as well as BioThrax, in its recently constructed, large-scale manufacturing facility at its Lansing campus. The acquisition of the rPA vaccine candidate further solidifies Emergent’s well established franchise of anthrax countermeasures, which now includes:

BioThrax®, the only FDA-approved vaccine to prevent the infection of anthrax. Nearly 2.0 million men and women of the United States military have received the vaccine, and HHS has procured more than 28 million doses of BioThrax for the SNS;

rPA 102, a recombinant anthrax vaccine candidate, which is composed of a purified protein with an alum adjuvant and is designed to induce antibodies that neutralize anthrax toxins;

AVP-21D9, a human monoclonal antibody product candidate being developed as an intravenous treatment for patients who present symptoms of anthrax disease; and

AIG, a polyclonal anthrax immune globulin product candidate, which is derived from human plasma from individuals who have been vaccinated with BioThrax.

“As the manufacturer of the only FDA approved anthrax vaccine, Emergent BioSolutions has a proven track record of delivering critical biodefense countermeasures to the U.S. Government. Given HHS’s stated commitment to procure up to an additional 25 million doses of a recombinant anthrax vaccine for the Strategic National Stockpile, we felt this was the right opportunity for our company at the right time,” said Fuad El-Hibri, chairman and chief executive officer of Emergent BioSolutions. “Additionally, we are pleased to provide the U.S. Government with the important option to select an advanced rPA anthrax vaccine candidate from a domestic manufacturer. As the premiere domestic biodefense supplier, this was a natural fit for us,” he continued.

Data reviewed to date relating to the rPA vaccine candidate suggests that the steps taken to address a prior stability issue affecting the vaccine position the product for continued development toward regulatory approval and to be a leading candidate for the HHS procurement contract of 25 million doses under the recently issued RFP.

Under the terms of the asset acquisition, Emergent BioSolutions paid VaxGen $2 million upon execution of the definitive agreement and may be obligated to pay up to an additional $8 million in milestone payments, plus specified percentages of future net sales.

About rPA 102
The vaccine candidate, rPA 102, is based on a recombinant form of the protective antigen protein. This vaccine contains a purified protein (rPA) formulated with an alum adjuvant and is designed to induce antibodies that neutralize anthrax toxins. The vaccine candidate does not cause anthrax infection and is based on the pioneering work of the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID). rPA 102 has been the subject of two research and development grants totaling approximately $100 million from the National Institute for Allergy and Infectious Diseases (NIAID). In 2004, HHS awarded VaxGen an $877 million contract for delivery of 75 million doses of rPA 102. The contract was subsequently terminated by HHS, based on its determination that VaxGen failed to successfully cure the condition endangering performance and failed to meet a milestone imposed by HHS that required VaxGen to initiate a clinical trial of the vaccine candidate by December 18, 2006. This failure was primarily related to stability issues with the vaccine.
