Fecal Microbiota Transplantation for Diarrhea/Colitis in Cancer Patients

This study is investigating if fecal microbiota transplantation (FMT) can help treat diarrhea or colitis (inflammation of the intestines) that is caused by immune-checkpoint inhibitor medications. These medications are used to treat various cancers, including genitourinary (kidney, bladder, prostate), melanoma, lung, and others. Participants will receive loperamide by mouth, followed by FMT through a colonoscopy. Researchers want to see how safe FMT is and if it can lead to clinical improvement or remission of the diarrhea/colitis. The study plans to enroll 40 adult patients who are currently receiving immune-checkpoint inhibitor treatment.

Study design
This is an interventional study with a planned enrollment of 40 participants. The phase of the study is not specified.
What's involved
You would receive loperamide by mouth, then undergo a fecal microbiota transplantation (FMT) via colonoscopy. The colonoscopy procedure takes 15-30 minutes.
Compensation
Not stated in the trial record.
Follow-up
After the study treatment, you will have follow-up visits at 2, 4, and 8 weeks, and then at 3 months.

  • Incidence of fecal microbiota transplantation (FMT)-related adverse eventsUp to 3 months post-FMT

    Assessed by Common Terminology Criteria for Adverse Events (CTCAE) version 5. All events are recorded with grade and attribution to FMT.

  • Clinical response/remission of immune-related diarrhea/colitisAt 2 weeks post-FMT

    Clinical remission of immune related events defined as improvement of symptoms of grade 1 or lower within 2 weeks post-FMT. Clinical partial response of immune related diarrhea/colitis defined as improvement of diarrhea/colitis to a lower grade than the initial presentation but not meeting criteria of clinical remission at 2 week post-FMT time point.
