PharmAthene's rPA Anthrax Vaccine Program Demonstrates 36 Month Product Stability

PharmAthene, Inc. PIP announced today that it has achieved an important program milestone in its recombinant protective antigen anthrax vaccine program and demonstrated 36 month stability of its rPA drug product candidate previously produced at Avecia Biologics Laboratories in the United Kingdom. The stability data were prepared utilizing a variety of analytical methods and a well characterized mouse challenge potency assay. Dr. Thomas Fuerst, Executive Vice President and Chief Scientific Officer, remarked, "Demonstration of 36 month final product stability is considered an important technical milestone under our current contract with the Biomedical Advanced Research and Development Authority (BARDA). We are extremely pleased to announce this achievement, which suggests that our rPA product candidate is both highly stable and potent. Stability has historically been a stumbling block for other recombinant anthrax vaccine programs, so we're especially excited about these ongoing results, which represent an important breakthrough for PharmAthene's rPA vaccine program.
