Recruiting studies
- NCT07086989Recruiting
Heart health study for kids with chronic conditions
This study looks at heart disease risk in children and young adults (ages 6-25) with long-term health conditions like certain heart, kidney, or diabetes disorders. The goal is to better understand and manage heart risks early.
BudapestAges 6–25 - NCT07529236Recruiting
How Children's Bowel Disease Responds After Switching IBD Medications
This study follows children who had to stop one type of IBD medicine (anti-TNFα) because it caused a skin condition called psoriasis, and were switched to a different medicine called ustekinumab. Researchers want to see how well their bowel disease is controlled with the new treatment.
Nice, FranceAges 6–17 - NCT03913962Recruiting
Exercise study for children with chronic or autoimmune conditions
This study looks at how physical activity affects muscle, metabolism (how your body uses energy), and body composition in children with certain chronic or autoimmune conditions. It may help doctors understand what types of exercise and monitoring are most beneficial and safe.
Clermont-FerrandAges 6–18 - NCT03894228Recruiting
Study of Crohn’s and colitis medicines during pregnancy and breastfeeding
This registry study tracks outcomes for mothers with inflammatory bowel disease (IBD) and their babies during pregnancy and breastfeeding while using IBD medicines. It aims to better understand the safety of these medicines so future pregnancies can be managed more confidently.
Santiago de Compostela, A CoruñaAges 18 years+ - NCT05628701Recruiting
Testing two UC surgery reconstructions after colectomy
This trial compares two ways of reconnecting the bowel after subtotal colectomy and ileostomy in people with ulcerative colitis (UC). It may help determine which surgical option works best when the rectum is calm enough to manage with topical mesalazine alone.
GothenburgAges 18–60 - NCT03855657Recruiting
Biobank study of gut microbes, genes, and blood chemistry
This study collects samples to learn how gut microbes, genetics, and body chemistry may relate to Crohn’s disease or ulcerative colitis. Your information and samples may help researchers understand disease patterns, but it does not test a new drug.
Hong KongAges 18 years+ - NCT07814456RecruitingPhase 2
Fecal transplant for ulcerative colitis comparing donor types
This trial tests fecal microbiota transplantation (a procedure that puts healthy donor bacteria into your gut) for left-sided ulcerative colitis. It compares results using donors from two different backgrounds to see if one works better.
Kunming, YunnanAges 18–60 - NCT03787771Recruiting
Fecal transplant registry for donors and recipients
This is a registry that collects information from adults who either receive fecal microbiota transplant (FMT) or plan to receive it, and from people who have donated—or plan to donate—stool for FMT. It helps researchers understand who participates in these gut-microbiome treatments in real life.
Hong KongAges 18 years+ - NCT07758335RecruitingPhase 4
Probiotics and trace elements for ulcerative colitis
This trial tests whether adding a probiotic supplement and trace elements to your current treatment helps manage mild to moderate ulcerative colitis. It aims to see if these additions can improve symptoms and quality of life.
CairoAges 18–65 - NCT07752446Recruiting
Mediterranean diet and time-restricted eating for ulcerative colitis
This study tests whether following a Mediterranean diet and limiting eating to a certain time window each day can help maintain remission in people with ulcerative colitis. It aims to see if this lifestyle change can keep the condition from flaring up.
Santiago, Santiago MetropolitanAges 18–60 - NCT07652294Enrolling by invitationPhase 2
Long-term safety of antibodies for IBD maintenance
This trial is testing long-lasting antibodies given alone or in combinations to keep IBD under control over the long term. It's for people who already did well in the initial study and want to continue treatment.
Lancaster, CaliforniaAges 18 years+ - NCT07621367Recruiting
Gut oxygen therapy for bowel problems from low oxygen
This trial tests a treatment that delivers oxygen directly to the gut through a small tube. It is for people with long-term heart failure or sleep apnea who also have belly pain, bloating, constipation, or diarrhea.
Nanjing, JiangsuAges 18 years+ - NCT06541938Recruiting
Breath test study for IBD in remission with IBS symptoms
This study tests a device called AIRE-2 that analyzes your breath to see if it can help manage IBD symptoms. It is for people with IBD who are in remission but still have IBS-like symptoms like belly pain or bloating.
Hamilton, OntarioAges 18–75 - NCT07612267RecruitingPhase 4
Mirikizumab Levels in Breast Milk During Treatment
This study measures how much of the medication mirikizumab passes into breast milk when mothers take it for their approved medical condition. The goal is to understand if it's safe for breastfeeding infants when mothers are receiving this treatment.
Glenview, IllinoisAges 3 weeks+ - 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 - NCT06287671Recruiting
Colorectal Surgery Tissue Study for Better Understanding of Disease
This study is collecting tissue samples from people having surgery on their colon or rectum to better understand colorectal diseases. It may help researchers learn more about conditions like cancer, polyps, or inflammatory bowel disease.
HillerødAges 18 years+ - 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 - 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 - 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+ - 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 - NCT06580418Recruiting
Study of an anti-TREM-1 drug in a gut model
This trial tests a new drug that blocks a protein called TREM-1, which may help reduce inflammation in the gut. It uses tissue samples from people with active ulcerative colitis or Crohn's disease to see if the drug is effective.
MilanAges 18–60 - 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 - NCT07347158Enrolling by invitation
Health education for ostomy patients
This study teaches people with an ostomy (a surgical opening for waste) about their health to improve their quality of life and reduce anxiety or depression. If you are an adult with a permanent or long-term ostomy and live in the Santiago or Barbanza area, you may be able to join.

Common questions
- Are there clinical trials for bowel disease?
- Yes. Clin2 currently lists 275 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.
