Recruiting studies
- NCT05185609Recruiting
Tests anal function in people with inflammatory bowel disease
This study checks how well the anal area works in people with inflammatory bowel disease (IBD), even when your bowel disease is “in remission” but you may still have symptoms. It may help doctors better understand the cause of ongoing problems and guide future care.

Brain-gut sensitivity study in IBS and inflammatory bowel disease
This study checks how sensitive your gut is to normal stimuli in people with IBS, ulcerative colitis, Crohn’s disease, and in healthy volunteers. Results may help researchers understand why some people feel more abdominal discomfort and how that connects to inflammatory bowel conditions.

Fecal transplant for gut and immune-related conditions
This trial studies whether fecal microbiota transplantation (FMT)—a medical procedure using stool from a screened donor to restore gut bacteria—can improve safety and outcomes for people with certain bowel, immune, and metabolic conditions. It may help if your symptoms are thought to be related to an unhealthy gut microbiome, though eligibility is broad and depends on specific safety factors.
Hong Kong, ShatinAges Any age - NCT07769437Recruiting

Stool test study for inflammatory bowel disease vs. irritable bowel syndrome

LiègeAges 18–75 - NCT06960369RecruitingPhase 1
Brain stimulation and probiotics for diarrhea-predominant IBS
This trial tests whether combining a type of brain stimulation (repetitive transcranial magnetic stimulation) with a probiotic tablet can help people with diarrhea-predominant irritable bowel syndrome. It aims to improve symptoms by targeting both the brain and the gut.
Suzhou, JiangsuAges 18–70 - NCT06940596Recruiting
Comparing diets and therapies for irritable bowel syndrome
This study compares different dietary and behavioral treatments to find out which works best for different people with irritable bowel syndrome (IBS). You'll be asked to follow a specific treatment program to see how it affects your symptoms.

Study early Parkinson signs in people with IBS
This study looks for early clues of Parkinson’s disease in people who have IBS (irritable bowel syndrome), and compares them with people without IBS. The goal is to understand whether gut symptoms or test results can help spot Parkinson’s earlier.
ÖrebroAges 18–85 - NCT03613545RecruitingPhase 2/Phase 3
Fecal transplant to treat irritable bowel syndrome
This study tests whether transferring stool bacteria from a healthy donor (fecal microbiota transplantation) can improve symptoms of irritable bowel syndrome (IBS). It may help by changing the gut bacteria that can influence digestion and gut discomfort.

Common questions
- Are there clinical trials for irritable bowel disease?
- Yes. Clin2 currently lists 91 recruiting irritable 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 irritable 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 irritable 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.
