About this study
Official title: Safety and Efficacy of Healthy to Inflamed Pouch Fecal Microbiota Transplantation
The purpose of this research study is to assess the safety and efficacy of fecal microbiota transplant (FMT) in the treatment of chronic pouchitis.
Read the detailed description
The purpose of this research study is to assess the safety and efficacy of fecal microbiota transplant (FMT) in the treatment of chronic pouchitis. FMT has been successfully used in the treatment of recurrent Clostridiodes difficile infection and has shown benefit in the treatment of ulcerative colitis in clinical trials. The success of FMT in these patients is because of the reconstitution of the recipient's unhealthy gut bacteria with the donor's healthy gut bacteria.
Surgery to remove the colon is required in a subset of patients with ulcerative colitis that does not respond to medical therapy. In these patients, an internal pouch is created from small intestine to function as a stool reservoir and avoid an ostomy after the colon is removed. Inflammation of the pouch, pouchitis, is common after surgery and can manifest as diarrhea, pelvic pain, urgency and blood in the stool. Chronic pouchitis occurs in up to 20% of patients and there is no approved treatment. A number of studies have evaluated FMT in patients with chronic pouchitis, but have proven unsuccessful. This is likely because these studies have used stool from patients with a colon and transplanted it into patients with a pouch. This is problematic because the gut bacteria of the colon and pouch are not similar, and putting healthy stool from a colon may not reconstitute a healthy pouch microbiome. The specific purpose of this project is to transplant stool from patients with a healthy pouch to patients with an inflamed pouch.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Fecal Microbiota Transplant (FMT) in people with Chronic Pouchitis and Pouchitis, run by Maia Kayal at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 17 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Maia Kayal, MD, MS (212-241-0150, Maia.Kayal@mountsinai.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of patients with FMT related adverse events (time frame: 8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Aug 2026.
