In Brief

A Phase 2 clinical trial evaluating Bezlotoxumab, Placebo, and 1 other intervention for Inflammatory Bowel Diseases and Clostridium Difficile Infection. Completed, enrolled 61 participants across 1 site.

Detailed Summary

This is a randomized controlled trial to assess the clinical and microbiological impacts of FMT in combination with Bezlotoxumab (bezlo) compared to FMT in combination with placebo in patients with both inflammatory bowel disease (IBD) a and clostridium difficile infection (CDI). The investigators will prospectively enroll up to 150 IBD-CDI patients from 4 tertiary care FMT referral centers. Patients will be randomized 1:1 to either receive FMT in combination with Bezlo of FMT and a placebo infusion. Donor stool from healthy donors will be obtained from OpenBiome. OpenBiome is a nonprofit 501(c)(3) organization that provides hospitals with screened, filtered, and frozen material ready for clinical use. Patients will be enrolled and followed prospectively for 3 months post therapy. Stool and blood samples as well as clinical data will be collected at baseline, week 1, 8 and 12.
