Emergent BioSolutions Inc. announced that it has submitted a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) seeking approval of the manufacture of BioThrax® (Anthrax Vaccine Adsorbed) in Building 55, the company’s large-scale manufacturing facility. The sBLA is supported by data that demonstrate that BioThrax manufactured at large scale in Building 55 is comparable to BioThrax manufactured in the currently-licensed facility. This submission follows the company’s successful completion of the re-analysis of data from one of more than 30 comparability assays for BioThrax manufactured in the new facility as requested by FDA.
