WALTHAM, Mass.--(BUSINESS WIRE)--Results from the successful clinical trial of Oscient Pharmaceuticals’ (Nasdaq: OSCI) FACTIVE® (gemifloxacin mesylate) tablets for the five-day treatment of community-acquired pneumonia of mild to moderate severity (CAP) have been published in the July issue of the peer-reviewed Journal of Antimicrobial Chemotherapy, currently available in advance on-line. The data from the Phase III clinical trial comparing a five-day and seven-day course of treatment with FACTIVE for CAP formed the basis of the approval last month from the U.S. Food and Drug Administration (FDA) of FACTIVE for the five-day treatment of CAP. FACTIVE 320 mg once-daily is the only fluoroquinolone antibiotic currently approved in the U.S. for the five-day treatment of both CAP and acute bacterial exacerbations of chronic bronchitis (AECB).
