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.

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.
Leuven, Vlaams-BrabantAges 18–65 - NCT07519395RecruitingPhase 2
Camlipixant for abdominal symptoms in IBS-D and IBS-M
This study tests whether a new drug called camlipixant can reduce belly pain and other uncomfortable symptoms in people with irritable bowel syndrome that causes diarrhea or mixed symptoms. The trial compares camlipixant to a placebo (inactive pill) to see if it works better.
Anniston, AlabamaAges 18–80 - NCT07581756Recruiting
Brain Stimulation Treatment for Diarrhea-Prone Irritable Bowel Syndrome
This trial tests whether repeated magnetic stimulation applied to the scalp (a non-invasive procedure) can reduce diarrhea and belly pain in people with diarrhea-predominant IBS. The goal is to see if this brain-based treatment can improve your symptoms.
Suzhou, JiangsuAges 18–70 - NCT07471490Enrolling by invitation
Stool test study for inflammatory bowel disease vs. irritable bowel syndrome
This study collects stool samples and health information to help develop a new test that may tell the difference between inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). If you have not been diagnosed with a chronic gut disorder, you may be able to join.
Minneapolis, MinnesotaAges 2 years+ - NCT07436910Enrolling by invitation
Quality of life in inflammatory bowel disease
This study asks people with inflammatory bowel disease to fill out questionnaires about their quality of life. It aims to learn how the condition affects daily living and well-being.
CairoAges 18 years+ - NCT06657001Enrolling by invitation
Personalized nutrition study for gut health
This study uses information from your gut bacteria (microbiome) to create personalized nutrition advice. It is for people with gut conditions like IBD, IBS, or celiac disease, as well as healthy volunteers.
Rochester, MinnesotaAges 18 years+ - NCT05573542Enrolling by invitation
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 - NCT07114055RecruitingPhase 2/Phase 3
Ebastine for diarrhea-predominant IBS
This trial tests whether ebastine, an allergy medicine, can help relieve symptoms of diarrhea-predominant irritable bowel syndrome (IBS-D). If you have IBS-D and are at least 18, this study may offer a new option to manage your condition.
DhakaAges 18 years+ - 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.
Guangzhou, GuangdongAges 18–75 - NCT05740319Recruiting
Test stool transplant to treat irritable bowel syndrome
This trial studies fecal microbiota transplantation, which is transferring stool bacteria from a healthy donor to help rebalance gut microbes. If you have irritable bowel syndrome (IBS) that hasn’t improved after several standard treatments, this study may see whether it reduces your symptoms and is safe.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06124833Recruiting
Gut and mouth microbiome study for Korean IBD patients and their family

Common questions
- Are there clinical trials for irritable bowel disease?
- Yes. Clin2 currently lists 99 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.
