Summary

The objectives of this study are: (1) to evaluate the safety and tolerability of VP 20621 dosed orally for up to 14 days in adults previously treated for CDI; (2) to characterize the frequency and duration of stool colonization with the VP 20621 strain of C. difficile; (3) to evaluate the efficacy of VP 20621 for prevention of recurrence of CDI; and (4)to select a dose regimen of VP 20621 to be used in future studies.
