Safety of FMT: OpenBiome Outcomes and Longitudinal Follow-up (STOOL) for Recurrent Clostridium Difficile Infection

• Status: Terminated
• Trial end date: 2018-06-01
• Target enrollment: 0
• Participant gender: All

Summary

The overarching objective of this study is to address the knowledge gap regarding the short-term and long-term safety of fecal microbiota transplants (FMT). The design will be a prospective, open-label, multi-center longitudinal cohort study to assess the short- and long-term safety of FMT as well as the clinical resolution of diarrhea among 150 patients with 3 or more episodes of clostridium difficile infection (CDI defined as 3 unformed stools over 24 hours for 2 consecutive days and either a positive stool test for CDI or pseudomembranes on colonoscopy/sigmoidoscopy). Subjects will be adult outpatients referred to one of the study centers after at least three recurrent episodes of CDI and previous treatment with at least one 10-day course of oral vancomycin or fidaxomicin. After FMT by colonoscopy/sigmoidoscopy or enema, patients will be followed prospectively and monitored for clinical resolution and adverse events at: 3 days (telephone), 3 weeks (clinical assessment), 8 weeks (telephone), 6 months (telephone), and 12 months (telephone) after FMT. Subjects who recur will be offered a second FMT by colonoscopy with a different donor. Microbiome analysis will be conducted from stool samples at baseline and each of the 5 follow-up intervals.
