Recruiting studies
- NCT06776029RecruitingPhase 2

Fecal transplant to ease constipation in irritable bowel syndrome
This trial tests whether transferring stool bacteria to the gut (fecal microbiota transplantation) can reduce symptoms of irritable bowel syndrome with constipation. It may help by changing the gut microbiome, but you must meet safety and health requirements.
RomaAges 18 years+ - NCT05803980Recruiting
Fecal transplant to ease IBS diarrhea symptoms
This study tests whether fecal microbiota transplantation (a stool-based treatment to change gut bacteria) can reduce symptoms of irritable bowel syndrome (IBS) that comes with diarrhea. You may be eligible if you’re an adult with diarrhea-predominant IBS and recent colonoscopy results that rule out other intestinal diseases.
RomaAges 18 years+ - NCT07319364RecruitingPhase 1
Fecal transplant study for cancer treatment side effects
This trial tests whether fecal transplants (putting healthy donor bacteria into your gut) can help with side effects like diarrhea, constipation, or nausea caused by cancer treatments. It is for people with advanced gastrointestinal cancer who are about to start their fourth round of chemo or targeted therapy.
Zhejiang, HangzhouAges 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+ - 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 - 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+ - NCT07083882RecruitingPhase 2
Capsule transplant for newly diagnosed type 1 diabetes
This study tests if taking capsules with processed donor stool can help preserve insulin-making cells in people recently diagnosed with type 1 diabetes. The treatment aims to slow the loss of insulin production.
AmsterdamAges 18–45 - NCT05035342RecruitingPhase 3
Fecal transplant to clear resistant gut bacteria
This Phase 3 study tests whether a fecal microbiota transplant (FMT) can eliminate hard-to-treat bacteria in the gut, such as ESBL or carbapenem-resistant bacteria. If it works, it may reduce future infections and antibiotic-resistant illness.
ClichyAges 18–105 - NCT07042438RecruitingPhase 2
Fecal transplant to improve CAR T therapy for lymphoma
This study tests whether a fecal transplant (transferring healthy gut bacteria) can improve outcomes for people with certain lymphomas who have taken strong antibiotics and are about to get CAR T-cell therapy (Yescarta). The goal is to see if rebuilding gut bacteria helps the treatment work better.
Duarte, CaliforniaAges 18 years+ - 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+ - NCT04997733RecruitingPhase 3
Stool transplant to maintain Crohn’s remission after stopping anti-TNF
This Phase 3 study tests whether transplanting stool bacteria can help people with Crohn’s stay in remission after they stop an anti-TNF medicine. It may help some patients who are currently doing well but need to come off anti-TNF treatment.
ParisAges 18–74 - NCT05967871RecruitingPhase 1
Testing poop-based therapy for kids with SIBO
This early study tests whether fecal microbiota transplant (a stool donation placed into the gut) is safe and practical for children with small intestinal bacterial overgrowth (SIBO). It may help reduce SIBO symptoms, but the main goal is to see if the treatment and study steps work well.
Hamilton, OntarioAges 3–18 - 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 - NCT06563947RecruitingPhase 2
Fecal transplant for advanced liver cancer after treatment stops working
This trial tests whether giving a fecal transplant (a procedure that replaces the bacteria in your gut) can help people with advanced liver cancer whose current treatment has stopped working. It may help boost your immune system to fight the cancer.
ShenzhenAges 18–75 - NCT06282952Recruiting
Stool transplant for C-section babies' health
This trial tests whether giving a special stool transplant (fecal microbiota) to healthy babies born by C-section can improve their health. It aims to see if this treatment helps replace good bacteria that are normally passed during a vaginal birth.
OuluAges birth–6 hours - NCT06290258RecruitingPhase 1/Phase 2
Fecal transplant for autism with stomach issues
This study tests if transplanting healthy bacteria into the gut can help children and young adults with autism who also have stomach problems. It aims to improve both digestive and behavioral symptoms.
Taoyuan CityAges 7–30 - NCT06218602RecruitingPhase 2
Fecal transplant for lymphoma patients getting CAR T therapy
This trial tests whether giving a fecal transplant (a stool enema from a healthy donor) can improve the response to CAR T-cell therapy in people with B-cell lymphoma. It may help by restoring healthy gut bacteria that are often wiped out by strong antibiotics.
Houston, TexasAges 18 years+ - NCT05829109RecruitingEarly Phase 1
Stool transplant for long-term inflamed pouch after surgery
This early-phase study tests fecal microbiota transplant (a stool-based treatment) to improve chronic pouchitis symptoms in adults after UC-related surgery. It may help by changing gut bacteria, especially for people who need ongoing antibiotics or keep having flare-ups.

Fecal transplant to treat moderate to severe IBS symptoms
This trial tests whether putting stool (fecal microbiota) from a donor into your bowel can improve symptoms in people with IBS who are not IBS-C. It may help by changing the gut bacteria that can influence IBS symptoms.
Rochester, MinnesotaAges 18–70 - NCT05739825Recruiting
Fecal transplant to change gut bacteria in C. difficile infection
This trial studies whether fecal microbiota transplantation (a procedure that transfers healthy stool bacteria) can change a person’s gut bacteria after repeated C. difficile infection. It may help reduce recurring infections by restoring a healthier balance of gut microbes.

Common questions
- Are there clinical trials for fecal microbiota transplantation?
- Yes. Clin2 currently lists 97 recruiting fecal microbiota transplantation studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a fecal microbiota transplantation trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a fecal microbiota transplantation trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
