Leuven, Vlaams BrabantAges 18 years+ - NCT07252427Recruiting
Gut bacteria in IBD with or without depression
This study looks at how the bacteria in your gut (gut microbiome) may differ between people with IBD who also have depression and those who don't. It aims to help understand the link between gut health and mood.

Online treatment for kids with stomach pain
This study tests an internet-based program to help children and teens with certain long-term stomach conditions, like irritable bowel syndrome (IBS) or ongoing stomach pain. It aims to see if online tools can reduce symptoms and improve daily life.
StockholmAges 8–17 - NCT07349472RecruitingPhase 2
Pentoxifylline for ulcerative colitis
This trial tests if the drug pentoxifylline can help people with mild to moderate ulcerative colitis. It may offer a new treatment option for those not on other strong medications.
Al FayyumAges 18–70 - NCT07373457RecruitingPhase 1
Testing a new drug in healthy volunteers
This early-stage study tests a new investigational drug called HW201877 in healthy volunteers. The goal is to see if the drug is safe and how the body processes it.
ChangchunAges 18–55 - NCT01650311Recruiting
Study how serotonin signals work in inflammatory bowel disease
This study looks at how the body’s serotonin system behaves in people with Crohn’s disease or ulcerative colitis, compared with healthy people. It may help researchers understand disease biology and why symptoms can differ from person to person.
Hamilton, OntarioAges 19–85 - NCT02614911Recruiting
Genetics and health profile study for early severe bowel disease
This study looks at how an early-onset bowel illness looks and what genetic changes may be involved. It may help researchers better understand inherited causes and improve future care for families affected by these conditions.
BordeauxAges Any age - 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+ - NCT07423000RecruitingPhase 1
Testing PVT401 in healthy volunteers
This study tests a new investigational drug called PVT401 in healthy people. It is a first-in-human study to see how the drug is handled by the body and to check for any side effects.
Melbourne, VictoriaAges 18–65 - NCT07591012Recruiting
Probiotic Supplements for Ulcerative Colitis Remission
This trial tests whether taking sodium butyrate (a short-chain fatty acid) and a specific probiotic yeast called Kluyveromyces marxianus can help keep ulcerative colitis in remission and prevent flare-ups. You'd need to be in remission (symptom-free with no active inflammation) when you start.
PadovaAges 18–75 - NCT07619638Recruiting
Microbiome Supplement for Mild-to-Moderate Ulcerative Colitis
This trial tests a specially designed supplement that aims to restore healthy gut bacteria in people with mild-to-moderate ulcerative colitis. The goal is to reduce inflammation and improve symptoms like rectal bleeding and bowel urgency.
IzmirAges 18–75 - NCT07475052Enrolling by invitation
Heart rate monitoring to predict biologic therapy response in IBD
This study tests whether a wearable heart rate monitor can help predict how well biologic medications work for people with Crohn's disease or ulcerative colitis. If you are starting infliximab or vedolizumab for the first time, you may be eligible.
Xi'an, ShaanxiAges 18–75 - NCT07347158Enrolling by invitation
Health education for ostomy patients

's-Hertogenbosch, North BrabantAges 18 years+ - NCT03756649Enrolling by invitation
IBD biobank study for adults and young adults
This study collects and stores information and samples from people with inflammatory bowel disease (IBD) to help researchers learn more and improve care. Your participation mainly helps build a “biobank,” which can support future studies.
Rochester, MinnesotaAges 18–85 - NCT07111715Recruiting
AI vs. standard reading for suspected Crohn disease
This study tests whether an artificial intelligence (AI) system can help doctors find signs of Crohn's disease better than standard reading of capsule endoscopy images. It is for people who have symptoms that might be Crohn's but whose colonoscopy didn't clearly show the problem.
BresciaAges 18–75 - NCT07750535Recruiting

Common questions
- Are there clinical trials for bowel disease?
- Yes. Clin2 currently lists 283 recruiting bowel disease 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 bowel disease 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 bowel disease 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.
