Fecal Microbiota clinical trials
We’re tracking 105 recruiting studies that include Fecal Microbiota, each written for real people, not researchers, below.
Recruiting studies
- NCT04373473RecruitingPhase 2
Oral stool treatment to prevent ulcerative colitis flare-ups
This study tests whether taking freeze-dried (lyophilized) donor stool material by mouth can help prevent ulcerative colitis from coming back or causing intestinal inflammation. Participants are in remission and stay on their usual treatment while receiving the study product.
Houston, TexasAges 18 years+ - NCT04264975Recruiting
Using gut microbiome tests and stool transfer in immunotherapy cancer
This trial studies whether changes in gut bacteria can help predict how well immunotherapy works for solid cancers. It also tests whether stool (fecal microbiota) from certain immunotherapy-responding people can improve outcomes for others who are not responding well.
Seoul, SeoulAges 19 years+ - NCT03819296RecruitingPhase 1
Fecal transplant to treat cancer immunotherapy bowel side effects
This early-phase study tests whether changing your gut bacteria with a fecal transplant can improve diarrhea or colitis caused by cancer immunotherapy. It may help people whose symptoms have not fully settled with standard treatments like steroids and other immune-blocking medicines.
Houston, TexasAges 18 years+ - NCT03148743Recruiting
Fecal transplant for gut graft-versus-host disease
This study tests whether a fecal transplant (FMT) can help treat gut graft-versus-host disease (gut GVHD), a condition where donated immune cells attack the intestines. If you have gut GVHD and meet age requirements, you may be eligible to receive this treatment in the trial.
Suzhou, JiangsuAges 10–60 - NCT02127398RecruitingPhase 2
Fecal transplants for hard-to-treat C. difficile infection
This Phase 2 study tests whether placing stool from a healthy donor into your gut can treat repeated, hard-to-control C. difficile colitis. It may help restore healthy gut bacteria and reduce future flare-ups.
Durham, North CarolinaAges 18 years+ - NCT06609980RecruitingPhase 1
Fecal transplant to restore gut health in infants
This study tests whether giving a baby’s own stool back to them (after it was stored before antibiotics) can help restore healthy gut bacteria. It’s for healthy infants and toddlers up to 4 years old who haven’t recently taken antibiotics.
New Brunswick, New JerseyAges 1 month–4 years - NCT07417085Recruiting
Study of gut bacteria in children with brain tumors
This study looks at how gut bacteria (the microbiome) may differ in children with brain tumors. Researchers will collect samples before and after surgery to understand the connection between gut health and brain tumors.
Florence, FirenzeAges 3–18 - NCT07385807Recruiting
Gut health and pregnancy in inflammatory bowel disease
This study looks at gut health in pregnant women with and without inflammatory bowel disease (IBD). It tracks a protein called calprotectin in stool samples, along with diet and baby health, to learn how IBD affects pregnancy and infant development.
Vancouver, British ColumbiaAges 19 years+ - NCT05449119Recruiting
Study links gut health, diet, and thinking and movement in seniors
This study looks at how differences in gut bacteria and nutrition may relate to changes in thinking and movement in people over 75 who have a reduced appetite (“small eaters”). It may help doctors better understand what could be contributing to these problems and how nutrition might play a role.

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.
