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 - NCT07401680RecruitingPhase 1
Stool transplant for active ulcerative colitis
This trial tests whether a stool transplant (fecal microbiota transplantation) can help manage active ulcerative colitis. You would receive a transplant from a healthy donor to see if it improves your symptoms.
Calgary, AlbertaAges 18 years+ - NCT07172191Enrolling by invitation
Fecal transplant for adults with blood cancer and infections
This trial tests whether transplanting healthy donor bacteria (fecal microbiota) into the gut can help adults with blood cancers who have stubborn infections, C. diff, or complications after stem cell transplant. It may reduce dangerous germs and improve gut health.
Budapest, BudapestAges Any age - NCT07154784Enrolling by invitationPhase 2/Phase 3
Fecal transplant for long-term ulcerative colitis treatment
This trial tests whether fecal microbiota transplantation (FMT) can safely and effectively treat mild to moderate ulcerative colitis over the long term. FMT involves transferring stool from a healthy donor to restore a healthy balance of gut bacteria.
Seoul, Dongjak-guAges 10–80 - 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+ - 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+ - NCT07348471Recruiting
Gut bacteria transplant for ICU delirium

- How do I know if I qualify for a Fecal Microbiota Transplantation 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 Transplantation 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 Transplantation or a specific trial is right for you.
