Prevention of Clostridium difficile Infection

This study will assess the safety and efficacy of VP 20621 for prevention of recurrence of Clostridium difficile infection (CDI) in adults previously treated for CDI with metronidazole or oral vancomycin. The objectives of this study are to:

• Evaluate the safety and tolerability of VP 20621 dosed orally for up to 14 days in adults previously treated for CDI
• Characterize the frequency and duration of stool colonization with the VP 20621 strain of C. difficile
• Evaluate the efficacy of VP 20621 for prevention of recurrence of CDI
• Select a dose regimen of VP 20621 to be used in future studies

Approximately 240 subjects will participate in the study from 50 sites in North America and Europe. The Reading Hospital is currently enrolling patients in the study, which is expected to remain open until October 2012.
