Capsule stool transfer for newly diagnosed inflammatory bowel or joint disease
This Phase 2 study tests whether taking capsule stool (FMT) is safe and can help people who are newly diagnosed and haven’t started the usual medicines yet. Participants will also start the standard first-line treatment for their condition, and the study will compare safety and outcomes.
OdenseAges 18–75 - NCT05186623Recruiting

Chicago, IllinoisAges 1–25 - NCT05219903Recruiting
Study of children with eosinophilic gut disorders
This study looks at children ages 0–18 with eosinophilic gut disorders (EGIDs) to better understand these conditions and how they are managed. It may help doctors improve care by comparing real-world information from patients followed at participating hospitals.
PaviaAges birth–18 years - NCT05294107Recruiting
Intestinal organoid study in digestive biopsies
This study collects small tissue samples (biopsies) during a routine endoscopy to create organoids—miniature versions of your intestine grown in a lab. The goal is to better understand digestive diseases and test potential treatments. You may be eligible if you're already scheduled for an endoscopy.
RennesAges 18–75 - NCT05313620RecruitingPhase 4
Tofacitinib effect on clotting tests in ulcerative colitis
This study looks at how tofacitinib (and related medicines) may affect clotting and blood-platelet function, and whether this could relate to blood clot risk. It includes detailed blood and stool/colonoscopy-related testing in adults with ulcerative colitis and in some people without it.
Madrid, MadridAges 18 years+ - NCT05332639Recruiting
Risk tracking test for Crohn’s disease in teens
This study checks whether a personalized tool can estimate someone’s risk for Crohn’s disease before symptoms start. It may help families learn early risk and decide on next steps sooner.
Boston, MassachusettsAges 14 years+ - NCT05574387RecruitingPhase 2
Metformin added to treatment for ulcerative colitis
This Phase 2 study tests whether adding metformin to usual care can help people with mild to moderate ulcerative colitis. The goal is to see if it improves symptoms and disease control compared with standard therapy alone.
Al MansurahAges 18–75 - NCT05575505RecruitingPhase 2
Pentoxifylline added to ulcerative colitis treatment
This trial tests whether adding the medicine pentoxifylline to standard care can help people with ulcerative colitis. It’s designed to see if this combination improves symptoms by changing inflammation.
Al MansurahAges 18–75 - NCT05615779Recruiting
Personalized fiber (B-fructan) diet for inflammatory bowel disease
This trial tests whether a tailored diet high in B-fructans can improve inflammatory bowel disease (ulcerative colitis or IBD-unclassified) in people in mild-to-moderate remission. It may help your gut and reduce bowel inflammation, and it involves colonoscopy and sample collection.
Edmonton, AlbertaAges 6–39 - NCT05633706Recruiting
Testing a capsule to study gut bacteria in the small intestine
This study tests the SIMBA capsule to learn how gut bacteria (dysbiosis) relate to digestive conditions. It may help researchers better understand these conditions and how the capsule can be used safely.
Calgary, AlbertaAges 18–80 - NCT05636709Recruiting
Follow-up study for adults starting GMA for Crohn’s or colitis
This study follows adults with inflammatory bowel disease (Crohn’s disease or ulcerative colitis) after their doctor starts a treatment called GMA. It mainly looks at safety and how patients do in real-world care, and may help doctors understand how GMA works over time.
Albacete, AlbaceteAges 18 years+ - NCT05652621Recruiting
Probiotics for people with ulcerative colitis symptoms
This study looks at whether probiotic pellets help people with inflammatory bowel disease, specifically ulcerative colitis. It may help improve gut symptoms, but the trial will test how well probiotics work for participants like you.
Xinxiang, HenanAges 18–80 - NCT05653011Recruiting
Study outcomes in people with inflammatory bowel disease
This study looks at what factors help predict how inflammatory bowel disease (IBD) may progress over time. You may be able to join if you are an adult with IBD and fit one of the study groups based on whether you have used TNF-blocking medicines before.

Study of why some bowel inflammation treatments don’t work
This study looks at blood and/or tissue “molecular” (cell-level) reasons why treatments don’t fully work in adults with Crohn’s disease or ulcerative colitis. If you are starting a biologic or small-molecule medicine and still have moderate to severe symptoms, you may be able to contribute to research that helps improve future care.

Common questions
- Are there clinical trials for colitis?
- Yes. Clin2 currently lists 321 recruiting colitis 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 colitis 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 colitis 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.
