Immunogenicity and Safety Study of a Three-Dose BioThrax® Regimen for Post-Exposure Prophylaxis in Healthy Adults

Completed · Phase 3

Conditions studied: Anthrax

In brief

The purpose of this Phase 3 clinical trial is to evaluate the immunogenicity and safety of BioThrax anthrax vaccine in healthy adults following 3 doses of BioThrax. Results of this study will be used to support a post-exposure prophylaxis (PEP) indication for BioThrax. This study will be conducted in the United States (U.S.), in 200 healthy male and female volunteer subjects ages 18 to 65 years. The duration of study participation for each individual subject will be approximately 128 days (4.25 months), including a screening period of approximately 28 days followed by 100 days on study.
