Brief Summary

This study will test the safety, effectiveness, and feasibility of a treatment called fecal microbiota transplantation (FMT) to reduce the symptoms of ICI-related diarrhea.

FMT uses a liquid preparation of stool collected from a healthy donor with normal (healthy) bacteria; this liquid is infused into the small or large intestine of a recipient during a colonoscopy procedure. The study researchers think that the healthy bacteria in the transplanted stool will grow and replace the unhealthy bacteria and return the intestines and colon of the recipient to a healthy state.

Conditions

Fecal Microbiota Transplantation (FMT)

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Fecal Microbiota Transplantation (FMT)

Study subjects will undergo standard bowel preparation and diagnostic colonoscopy with routine biopsies for pathologic assessment. FMT will be performed at the proximal extent of the colon reached, according to the same protocol used in prior randomized studies. FMT will use healthy donor stool provided by OpenBiome, a nonprofit 501(c)(3) organization that provides clinicians and hospitals with screened, filtered and frozen stool to be used for FMT. Routine clinical and research biopsies will be collected during the FMT colonoscopy procedure.

Group Type: EXPERIMENTAL

Fecal Microbiota Transplantation (FMT)

Intervention Type: BIOLOGICAL
