Microbiota Restoration Therapy for Recurrent Clostridium Difficile-associated Diarrhea

This is the first study of a microbiota suspension derived from intestinal microbes. The primary assessments for this open label, multi-center study are (i) occurrence of product-related adverse events and (ii) resolution of CDAD at 56 days after administration of RBX2660. Subjects will also be assessed for time to CDAD recurrence, quality of life changes, and number of hospitalizations and length of stay for recurrent CDAD. Study visits will be at 7, 30, and 60 days after RBX2660 administration with additional follow-up at 3 and 6 months post treatment. Patients who have had at least two recurrences of CDAD after a primary episode and have completed at least two rounds of standard-of-care oral antibiotic therapy or have had at least two episodes of severe CDAD resulting in hospitalization may be eligible for the study.
