Brief Summary:

Subjects with recurrent C. difficile infection will receive an oral dose of CP101 capsules one time in Treatment Group I or matching placebo one time in Treatment Group II. The purpose of this study is to demonstrate the safety and effectiveness of CP101 to prevent recurrence of C. difficile.

Subjects with confirmed C. difficile recurrence within 8 weeks after administration of study drug (CP101 or placebo) may be eligible to enroll in the open-label extension study (CP101-CDI-E02) and will receive CP101.
