ROCKVILLE, MD - Emergent BioSolutions Inc. (NYSE:EBS) recently announced that it has submitted a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) seeking to expand the label of BioThrax® (Anthrax Vaccine Adsorbed) to include a post-exposure prophylaxis (PEP) indication. BioThrax, the only FDA-licensed vaccine to prevent anthrax disease, is currently licensed for a pre-exposure prophylaxis indication only.
"This sBLA submission reflects years of collaboration between Emergent and the U.S. government to enhance the country's preparedness to meet immediate public health needs in the event of an anthrax attack. To date, these efforts have led to an enhanced route of administration, a streamlined vaccination schedule and an extended shelf life for BioThrax. The next milestones for this collaboration are an expanded product label to include PEP and an increase in our manufacturing capacity to a target of between 20-25 million doses per year," said Adam Havey, executive vice president and president biodefense division at Emergent BioSolutions.
The company made a Request for Priority Review Designation to potentially reduce the anticipated approval of this application to six months. The sBLA proposes to expand the BioThrax indication to include a post-exposure prophylaxis of disease resulting from suspected or confirmed Bacillus anthracis exposure when combined with the recommended course of antimicrobials in persons 18 through 65 years of age. The vaccination schedule consists of three doses of BioThrax administered at 0, 2, and 4 weeks post-exposure. This indication is supported by data from twelve non-clinical studies, three Phase 2/3 clinical trials, and a 2010 pre-Phase 3 Vaccines and Related Biological Products Advisory Committee (VRBPAC) meeting during which the regulatory pathway for licensure of anthrax vaccines for PEP was established.
All studies supporting licensure were fully funded under contract number HHSO100200700037C provided by the Biomedical Advanced Research and Development Authority within the Office of the Assistant Secretary for Preparedness and Response in the U.S. Department of Health and Human Services.
