Fecal transplant capsules for clearing drug-resistant bacteria from the gut
This trial tests whether taking capsules containing processed healthy donor stool (fecal microbiota transplant) can safely remove certain drug-resistant bacteria (like CRE, ESBL-E, and VRE) from your intestines. It may be an option for people who have these bacteria in their stool but are not currently being treated with antibiotics.
RijekaAges 18 years+ - NCT06001333Recruiting
Fecal transplant to clear superbugs from the gut
This study tests whether a fecal transplant (FMT) can remove certain antibiotic-resistant bacteria from your gut. It might help people who carry superbugs like CPE or VRE but aren't currently on antibiotics.
Chuncheon, Gangwon-doAges 20 years+ - NCT06692361Recruiting
Gut bacteria transplant for depression not helped by escitalopram
This trial tests whether transplanting healthy gut bacteria (fecal microbiota) can help people with depression that does not respond well to the antidepressant escitalopram. You will first take escitalopram for 2 weeks, and if it doesn't help enough, you may receive either the real transplant or a placebo capsule.
Wuhu, AnhuiAges 18–65 - NCT06623461RecruitingPhase 2
Fecal transplant with immunotherapy for advanced melanoma
This trial tests if giving a special capsule of donated bacteria (fecal transplant) alongside standard immunotherapy helps shrink tumors in people with advanced melanoma. It aims to see if adding the bacteria can make the immune therapy work better.
Abbotsford British Columbia, British ColumbiaAges 18 years+ - NCT06478823Recruiting
Healthy stool donors for fecal transplant studies
This trial is looking for healthy stool donors to provide samples for fecal microbiota transplantation, a treatment that uses healthy bacteria from stool to help people with certain gut diseases. As a donor, you would give stool samples regularly to help others.
Paris, ParisAges 18–49 - NCT06451588RecruitingPhase 2
Fecal transplant for inflammatory back pain
This study tests whether a fecal microbiota transplant (a procedure that transfers healthy bacteria into your gut) can reduce inflammation and improve symptoms in people with inflammatory back pain (axial spondyloarthritis). It may help if your current treatments are not working well enough.

Common questions
- Are there clinical trials studying Fecal Microbiota?
- Yes. Clin2 currently lists 105 recruiting studies that include Fecal Microbiota, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Fecal Microbiota trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Fecal Microbiota an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Fecal Microbiota or a specific trial is right for you.
