PharmAthene Awarded up to Additional $78.4 Million Under Existing Contract for Advanced Development of SparVax(TM) Anthrax Vaccine

February 23, 2010

ANNAPOLIS, Md., Feb. 23 /PRNewswire-FirstCall/ — PharmAthene, Inc. (NYSE Amex: PIP) a biodefense company specializing in the development and commercialization of medical countermeasures against chemical and biological threats, announced today that the Department of Health and Human Services (HHS), through the Biomedical Advanced Research and Development Authority (BARDA) has modified its existing research and development contract with PharmAthene providing for up to a total of $78.4 million in additional funding, provided that certain milestones are achieved and that all contract options and extensions are exercised by the government, to support the continued advanced development of SparVax(TM), a second generation recombinant protective antigen (rPA) anthrax vaccine targeted for future procurement in the U.S. Strategic National Stockpile (SNS).

“We are pleased to be awarded additional development funding for our SparVax(TM) anthrax vaccine program, which may offer a promising improved alternative to existing anthrax vaccine options,” commented David P. Wright, President and Chief Executive Officer. “There is widespread acknowledgement among various government agencies that the United States must develop and stockpile a second generation anthrax vaccine employing modern vaccine technology that offers the potential for improved safety, convenience and enhanced cost effectiveness. New and improved anthrax vaccines, based on modern state-of-the-art recombinant vaccine technology, incorporate significant product development and technological advancements and ultimately may provide meaningful health and economic advantages.”

In addition to the funding announced today, on February 1, 2010 PharmAthene also submitted a White Paper seeking further development funding for SparVax(TM), in response to a Broad Agency Announcement (Solicitation Number: BAA-BARDA-09-34).

“We believe that, if awarded, funding provided under the BAA, along with the additional funding announced today, could be sufficient to advance SparVax(TM) to a stage where it will be eligible for consideration for a Project BioShield procurement contract,” said Mr. Wright.

SparVax(TM) is a highly purified recombinant protective antigen vaccine being developed for pre and post exposure protection against anthrax infection. Phase I and Phase II clinical trials involving 770 healthy human subjects have been completed and demonstrated that SparVax(TM) appears to be well tolerated and immunogenic in humans. These studies suggest that three doses of SparVax(TM), administered over a 56 day period, are sufficient to induce protective immunity. The vaccination regimen for the currently licensed anthrax vaccine, BioThrax®, requires five doses over a period of eighteen months.

The contract modification, which is effective February 22, 2010 and extends until December 31, 2012, provides for up to $61 million during a “base period” of performance with options for an additional $17 million on a cost reimbursement plus fixed fee basis in additional advanced development funding for SparVax(TM). Provided that certain milestones are achieved, and that all contract options and extensions are exercised by the government, the contract has a total potential value of $78.4 million. The activities outlined under the contract modification are designed to continue existing development activities already under contract (HHSO100200900103C). The modification will include non-clinical safety and efficacy studies, assay development and qualification, and process scale up and validation.

“PharmAthene has a strong track record of successfully collaborating with a number of U.S. government agencies, including, the National Institutes of Health (NIH), BARDA, the United States Army Medical Research Institute for Infectious Diseases, and the Department of Defense, to advance the development of our biodefense product portfolio to address biological and chemical threats and preserve the security and well-being of our military personnel and citizens. We are deeply committed to providing improved medical countermeasures for anthrax, which is considered to be the number one biological threat facing the Nation. We applaud President Obama’s renewed commitment to protecting our Nation against the threat of bioterrorism and look forward to continuing our work with the government. It is our shared goal to develop the medical countermeasures necessary to successfully deter or quickly respond to a biologic attack and save American lives,” said Mr. Wright.

Including the additional funding announced today, PharmAthene’s SparVax(TM) program has been awarded funding commitments from the U.S. government totaling up to $213.2 million.

The rPA contract modification was announced via a Special Notice (Solicitation Number: HHSO100200900103C) rPA Anthrax Vaccine Advance Development, issued by HHS on December 29, 2009. The original development contract for rPA vaccine (N01-Al-30052) was issued in 2003 and transferred to BARDA on April 1, 2009.

About SparVax(TM)

SparVax(TM) is a novel second generation recombinant protective (rPA) anthrax vaccine being developed for pre and post exposure protection against anthrax infection. SparVax(TM) is a highly purified, well characterized, sub unit vaccine comprised of a single protein (recombinant PA) manufactured in E.coli. Phase I and Phase II clinical trials involving 770 healthy human subjects have been completed and showed that SparVax(TM) appears to be well tolerated and immunogenic in humans. These studies suggest that three doses of SparVax(TM), administered several weeks apart, should be sufficient to induce protective immunity. In non-clinical studies SparVax(TM) has also demonstrated the capability to protect rabbits and non-human primates against a lethal aerosol spore challenge of the anthrax Ames strain.
