Overview
Brief Summary
The purpose of this clinical trial is to determine whether there is any effect on the antibiotic, ciprofloxacin when taken before and after administration of a 3-dose series of BioThrax® (Anthrax Vaccine Adsorbed or AVA).
This study will be conducted in the United States (US) in 154 healthy male and female volunteer subjects ages 18 to 45.
The duration of study participation for each subject will be approximately 76 days (approximately 2.5 months)
Detailed Description
BioThrax is the only FDA-licensed vaccine for the prevention of anthrax infection. This is a randomized, open-label, Phase 2, multi-center trial to investigate the potential interactions of ciprofloxacin and BioThrax.
