A Phase 3 Open-Label Clinical Study to Evaluate the Safety and Tolerability of Rebiotix RBX2660 (Microbiota Suspension) in Subjects With Recurrent Clostridium Difficile Infection

2019-01

This is a prospective, multicenter, open-label Phase 3 study of a microbiota suspension of intestinal microbes. Patients who have had at least one recurrence of CDI after a primary episode and have completed at least one round of standard-of-care oral antibiotic therapy or have had at least two episodes of severe CDI resulting in hospitalization may be eligible for the study. Subjects may receive a second RBX2660 enema if they are deemed treatment failures following the initial enema per the protocol-specified treatment failure definition.
