Recruiting studies
- NCT06451588RecruitingPhase 2
Fecal transplant for axial spondyloarthritis
This trial tests whether a fecal microbiota transplant (a procedure that transfers healthy bacteria from a donor into your gut) can help reduce inflammation and improve symptoms of axial spondyloarthritis. It may be an option if your disease is active despite current treatments.
TromsøAges 18–65 - NCT06495333Recruiting
Gene and gut bacteria in Hispanic fatty liver patients
This study looks at how a gene variant (PNPLA3) relates to gut bacteria in Hispanic patients with fatty liver disease (MASLD) in Puerto Rico. It aims to understand the connection between your genes, your gut health, and your liver condition.
San JuanAges 21–75 - NCT06623461RecruitingPhase 2
Fecal transplant with immunotherapy for advanced melanoma
This trial tests if giving a special capsule of donated bacteria (fecal transplant) alongside standard immunotherapy helps shrink tumors in people with advanced melanoma. It aims to see if adding the bacteria can make the immune therapy work better.
Abbotsford British Columbia, British ColumbiaAges 18 years+ - NCT07106580RecruitingPhase 1/Phase 2
Fecal transplant capsules for clearing drug-resistant bacteria from the gut
This trial tests whether taking capsules containing processed healthy donor stool (fecal microbiota transplant) can safely remove certain drug-resistant bacteria (like CRE, ESBL-E, and VRE) from your intestines. It may be an option for people who have these bacteria in their stool but are not currently being treated with antibiotics.
RijekaAges 18 years+ - NCT07153809Recruiting
Fecal transplant for severe acute pancreatitis recovery
This trial tests whether a fecal transplant (transferring healthy gut bacteria from a donor) can help people with severe acute pancreatitis. It is for adults who are about 2 weeks past the onset of the disease and have started to recover but still have fluid buildup in the pancreas.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT07261826Recruiting
Long-term effects of fecal microbiota transplant
This study looks at how well fecal microbiota transplantation (FMT) works over time and checks its safety. If you have received at least one FMT for a qualifying condition, you may be able to participate.
Shanghai, Shanghai MunicipalityAges 3 years+ - NCT07363304Recruiting
How ETI therapy affects body and gut in cystic fibrosis
This study looks at how the triple combination therapy (elexacaftor/tezacaftor/ivacaftor, or ETI) affects your body's metabolism, epigenetics, and gut bacteria in people with cystic fibrosis. It aims to understand the broader health benefits of this treatment.
Bari, BariAges 2 years+ - NCT07374094Recruiting
Understanding C. difficile infection and treatment effects
This study is tracking patients with a confirmed C. difficile infection to understand how the body responds and how treatments work. You may be asked to do follow-up visits for up to 5 years.
UmeåAges 18 years+ - NCT07381374Recruiting
Fecal transplant for children with autism
This trial tests whether fecal microbiota transplantation can help children with moderate-to-severe autism. It involves giving healthy donor bacteria to improve gut health and possibly autism symptoms.
Shenzhen, GuangdongAges 3–16 - NCT01793831Recruiting
Fecal transplant study for people with Crohn’s disease
This study tests whether a standardized stool-based treatment (fecal microbiota transplantation) can help people with Crohn’s disease. You may qualify if your Crohn’s diagnosis has been stable and you’re willing to receive the fecal transplant.
Huai'an, JiangsuAges Any age - 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+ - 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 - NCT06692361Recruiting
Gut bacteria transplant for depression not helped by escitalopram
This trial tests whether transplanting healthy gut bacteria (fecal microbiota) can help people with depression that does not respond well to the antidepressant escitalopram. You will first take escitalopram for 2 weeks, and if it doesn't help enough, you may receive either the real transplant or a placebo capsule.
Wuhu, AnhuiAges 18–65 - 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+ - NCT05830591Recruiting
Gut microbiome study in autism in children
This trial studies differences in the gut bacteria (microbiome) between children with autism and healthy children. It may help researchers understand what roles the gut may play in autism and guide future treatments.
TriesteAges 1–17 - 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 114 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.
