Seattle, WashingtonAges 7–21 - 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+ - NCT03516461Recruiting
Fecal transplant study for bowel injury after radiation
This study tests whether transferring stool bacteria (a fecal microbiota transplant) can improve “radiation enteritis,” a bowel problem that happens after radiation treatment. It may help restore gut bacteria and reduce symptoms after your radiation therapy.
Nanjing, JiangsuAges 18–85 - NCT06205862RecruitingPhase 2
Fecal transplant for preventing colon polyp return
This study tests whether taking capsules of healthy bacteria (fecal microbiota transplant) can help prevent colon polyps from coming back after they have been removed. It might be an option for people who have had an adenoma polyp removed and want to reduce the chance of recurrence.
Guangzhou, GuangdongAges 18–75 - NCT06262451Enrolling by invitation
Fecal transplant national registry study
This study creates a registry for people who receive fecal microbiota transplants (FMT) to track long-term safety and outcomes. It may help researchers understand how this treatment works over time.
San Francisco, CaliforniaAges Any age - NCT07094984Recruiting
Clearing resistant gut bacteria: three FMT methods
This trial tests three different ways to clear antibiotic-resistant bacteria from your gut using fecal microbiota transplant (FMT). It may help if you have a confirmed resistant infection and are looking for a treatment to reduce the risk of future infections.
WarsawAges 18 years+ - NCT07387952Recruiting
Fecal transplant with nutrition help for chronic constipation
This trial tests if a fecal microbiota transplant combined with nutritional support can improve chronic constipation that hasn't gotten better with standard treatments. It's a small early study to see if the approach is safe and works.
BeijingAges 18–70 - NCT06346093Recruiting
Fecal transplant for advanced stomach cancer
This trial tests whether a fecal transplant (a stool donation from a healthy person) can help patients with advanced stomach cancer respond better to treatment. If you qualify, you would receive the transplant through a colonoscopy, possibly along with other standard therapies.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07276100RecruitingPhase 2
Fecal transplant to help liver cancer that worsened on first treatment
This trial tests whether transplanting healthy stool bacteria into your gut can help your own immune system fight liver cancer that has stopped responding to the standard first combination treatment (atezolizumab + bevacizumab). It is for patients whose liver cancer has started growing quickly despite that treatment.
Bologna, BOAges 18 years+ - NCT05067595RecruitingPhase 1
Fecal transplant plus fiber for gut graft-versus-host disease
This Phase 1 study tests whether a fecal microbiota transplant (a stool-based treatment from a screened donor) plus a dietary fiber supplement can improve gut symptoms after a bone marrow transplant. It is aimed at people with mild to severe gut graft-versus-host disease (GVHD).
Seattle, WashingtonAges 18 years+ - NCT06782880Recruiting
Fecal transplant to prevent infections after liver transplant
