New Dosage Regimen Approved for BioThrax
Emergent BioSolutions Receives FDA Approval for BioThrax Supplemental Biologics License Application
Reduced Dosage and Intramuscular Administration Approved
ROCKVILLE, Md.--(BUSINESS WIRE)--Dec 19, 2008 - Emergent BioSolutions Inc. announced today that the U.S. Food and Drug Administration (FDA) has approved Emergent's supplemental Biologics License Application (sBLA) for Anthrax Vaccine Adsorbed (BioThrax), the only FDA-licensed vaccine to prevent disease caused by Bacillus anthracis. The supplement provides for a change in the route of administration and a reduction in the total number of vaccinations. The new schedule for BioThrax is five intramuscular (IM) doses at 0, 1, 6, 12 and 18 months, compared with the former schedule of six subcutaneous (SC) doses at 0, 2 weeks and 1, 6, 12, 18 months.
The sBLA was based on results from a planned interim analysis of data from a large multicenter study initiated by CDC in 2002. This study is designed to evaluate whether as few as three doses of BioThrax administered over six months, with booster doses up to three years apart, will confer an adequate immune response. CDC will complete further data analysis in 2009, and Emergent may submit a new sBLA to allow for further reduction in the number of required doses if supported by the data.
Daniel Abdun-Nabi, chief operating officer and president of Emergent BioSolutions said, "Today's announcement is an exciting milestone in our continued mission to advance BioThrax. We are pleased that the U.S. Government shares our commitment to enhancing this critical countermeasure. The CDC is to be applauded for their hard work and diligence throughout this important effort."
