Stool transplant as first treatment for kids with Crohn’s
This study tests whether transferring healthy gut bacteria from stool into the colon can work as a first treatment for children newly diagnosed with mild-to-moderate Crohn’s disease. It may help reduce inflammation and improve symptoms, and it requires regular colonoscopy to monitor progress.

Capsule fecal transplant to prevent C. difficile coming back
This study tests whether taking a capsule form of fecal microbiota transplant (FMT) can help adults with their first C. difficile infection—or a first relapse—get better and reduce repeat episodes. Participants also take specific antibiotics for C. difficile as part of the study process.
Basel, BaselAges 18 years+ - NCT05067595RecruitingPhase 1
Fecal transplant and fiber for gut graft-versus-host disease
This study tests whether a fecal microbiota transplant (a procedure that puts healthy donor bacteria into your gut) combined with a dietary fiber supplement can help treat gut graft-versus-host disease, a common complication after a stem cell transplant. It may help reduce diarrhea and other gut symptoms.
Seattle, WashingtonAges 18 years+ - NCT04935684RecruitingPhase 2
Fecal transplant after bone marrow transplant to improve gut health
This Phase 2 study tests whether a fecal microbiota transplant (a processed transplant of gut bacteria) after an allogeneic bone marrow transplant is safe and helpful. Participants may benefit by improving recovery in the gut microbiome during the post-transplant period.
AmiensAges 18 years+ - NCT04038619RecruitingPhase 1
Fecal transplant for immune-therapy diarrhea or bowel inflammation
This early-phase study tests whether stool/fecal microbiota transplant (a fecal transplant) can help people who develop significant diarrhea or colitis after immune-checkpoint therapy. It aims to reduce bowel inflammation and improve symptoms, while carefully checking for infections.
Houston, TexasAges 18 years+ - NCT03325855Recruiting
Fecal transplant registry for patients and donors
This study is a national “registry” that collects information from people who get fecal microbiota transplant (a stool-based treatment) and from people who donate stool. It helps researchers understand who receives these treatments and how they do over time.
Phoenix, ArizonaAges Any age - 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+ - NCT03562741Recruiting
Tracking outcomes of fecal transplant for repeated C. difficile
This study looks at how fecal microbiota transplantation (a transplant of healthy gut bacteria) works for people who get C. difficile infection repeatedly. It also focuses on collecting follow-up information to better understand which patients benefit and how.
Worcester, MassachusettsAges 16 years+ - NCT02636517Enrolling by invitationPhase 1
Fecal microbiome transplant for repeat C. difficile infection
This Phase 1 study tests whether transferring healthy gut bacteria (a fecal microbiome transplant) can help children with repeated or moderate-to-severe C. difficile infection. It focuses on changing gut bacteria to reduce ongoing infection and symptoms.
Philadelphia, PennsylvaniaAges 3–21 - NCT01868373Enrolling by invitationPhase 1
Fecal transplant study for hard-to-treat C. difficile diarrhea
This Phase 1 study tests defined fecal microbiota (healthy gut bacteria) given to people with C. difficile diarrhea that didn’t go away or came back soon after antibiotics. It may help by restoring a healthier balance of gut bacteria so the infection can stop recurring.
Houston, TexasAges 18 years+ - NCT05516472RecruitingEarly Phase 1
Fecal transplant study for people with frequent kidney stones
This trial tests whether transplanting donated stool microbiome (fecal microbiota transplantation) can change gut bacteria and help reduce harm from frequent kidney stones. You would provide urine and stool samples and have follow-up checks to watch for side effects.
Park City, UtahAges 18–69 - NCT01905709Recruiting
Fecal transplant to treat recurring C. difficile infection
This trial studies using a fecal microbiota transplant (FMT)—healthy gut bacteria moved from a screened donor—to help treat recurring or hard-to-control C. difficile infection. It may help restore a healthier gut environment when standard treatments keep failing or the infection returns.
Englewood, New JerseyAges 18 years+ - NCT07348471Recruiting
Gut bacteria transplant for ICU delirium
This study tests whether giving a transplant of healthy gut bacteria (called fecal microbiota transplantation) can help treat delirium in ICU patients. It may improve brain function by restoring gut health.
WuhanAges 18–80 - NCT05690048RecruitingPhase 2
Fecal transplant to help liver cancer respond to standard drugs
This trial studies whether a fecal microbiota transfer (a “gut bacteria transfer” from a donor) can help liver cancer patients overcome resistance to atezolizumab and bevacizumab. It aims to improve how well the standard medicines control the cancer.
Heidelberg, Baden-WurttembergAges 18 years+ - NCT05024188Recruiting
Gut bacteria and exercise performance study
This study looks at how the bacteria in your gut might affect your physical fitness and exercise ability. You would need to be a regular exerciser and take some antibiotics as part of the study.
RehovotAges 20–55 - NCT05786404RecruitingPhase 1
Fecal transplant study for people with active ulcerative colitis
This trial tests whether transplanting stool bacteria (called fecal microbiota transplantation, or FMT) can improve symptoms in people with active ulcerative colitis. You may be able to help test a new approach for restoring gut bacteria, while receiving standard ulcerative colitis care from your doctor.
Houston, TexasAges 18 years+ - NCT03787771Recruiting
Fecal transplant registry for donors and recipients
This is a registry that collects information from adults who either receive fecal microbiota transplant (FMT) or plan to receive it, and from people who have donated—or plan to donate—stool for FMT. It helps researchers understand who participates in these gut-microbiome treatments in real life.
Hong KongAges 18 years+ - NCT07464392Recruiting
Fecal transplant to prevent infections in severe pancreatitis
This trial tests whether a fecal microbiota transplant (FMT) can help prevent infections in people with moderately severe or severe acute pancreatitis. You may qualify if you are between 18 and 75, have had pancreatitis for 15 to 21 days, and already have a feeding tube in place.
Fuzhou, FujianAges 18–75 - NCT07381374Recruiting
