Women's Medicine Collaborative


This study is for individuals with a diagnosis of inflammatory bowel disease (IBD) who have experienced multiple Clostridium difficile infections (C. diff or CDI). This study will assess the efficacy of fecal microbiota transplant (FMT) in combination with an infusion of Bezlotoxumab (an antibody) compared to FMT alone. This research study is funded by Merck and Company.

  • 18 years of age or older.

  • Have a diagnosis of inflammatory bowel disease (IBD).
  • Undergoing FMT via colonoscopy for CDI as part of standard medical care.
