Recruiting studies
- 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 - NCT05582174RecruitingPhase 4
IV medicine versus pills to stop bleeding stomach ulcers
This trial compares an IV “acid-suppressing” medicine (PPI infusion) with acid pills (oral PPIs) after doctors treat a bleeding peptic ulcer endoscopically. It may help prevent re-bleeding by keeping stomach acid low while the ulcer heals.
Guangzhou, GuangdongAges 18 years+ - NCT05613985Recruiting
Ultrasound light added to usual care for infected diabetic foot ulcers
This trial tests whether adding the VULNOFAST Plus/VULNOLIGHT system to usual care can heal infected diabetic foot ulcers more safely and effectively. It compares the added treatment plus usual care versus usual care alone.
ArezzoAges 18 years+ - 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.
Seongnam-si, Gyeonggi-doAges 18 years+ - NCT05698745Recruiting
Study of the immune features soon after bowel disease starts
This study looks at immune system changes in people around the time inflammatory bowel disease (IBD) is first diagnosed, and compares different groups (new, very recent, or not found on scope). It may help researchers understand what the immune system looks like early in IBD and later in people who don’t show it on colonoscopy.
Santiago de Compostela, A CoruñaAges 18 years+ - NCT05704413Recruiting
Biobank study using gut tissue in bowel disease
This study collects and stores digestive (bowel) tissue to better understand how gut bacteria may affect diseases like ulcerative colitis or Crohn’s disease. It may help researchers find future ways to improve care for people with these conditions.
ParisAges 18 years+ - NCT05705024RecruitingPhase 2
Eye drops/treatment to heal stubborn cornea surface damage
This Phase 2 trial tests a locally delivered cell-based treatment (allogeneic mesenchymal stromal cells) to help heal long-lasting damage to the eye’s clear surface (the cornea). It may help if your cornea epithelium (surface layer) won’t improve even after standard non-surgical treatments.
Chicago, IllinoisAges 18 years+ - NCT05722236Recruiting
Peer support program to help people manage stress from IBD
This trial tests a “peer-to-peer” support program to help adults with inflammatory bowel disease (IBD) manage psychological distress (stress and emotional strain). It may help you cope better during major life or treatment changes related to IBD.
Halifax, N.S.Ages 18–99 - NCT05733845Recruiting
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.
Vandœuvre-lès-Nancy, CHRU de NancyAges 18 years+ - NCT05743374Recruiting
Diet changes with micronutrients for ulcerative colitis
This trial looks at whether changing your diet with certain vitamins or minerals (micronutrients) and other diet additives can improve health in people with moderately active ulcerative colitis. You may be asked to follow a specific diet plan, while your symptoms and medication stability are monitored.
Malmö, Skåne CountyAges 18 years+ - NCT05767047RecruitingPhase 3
Apremilast study for children with mouth ulcers from Behçet’s
This trial studies whether apremilast can help reduce mouth ulcers in children who have Behçet’s disease or juvenile psoriatic arthritis. You may be considered if your child finished a main study and is under 18, and can safely continue treatment.
ThessalonikiAges 5–18 - NCT05835973Recruiting
Study of sleep changes in people with inflammatory bowel disease
This study looks at how sleep patterns change in adults with inflammatory bowel disease (IBD) who are currently in remission. It may help researchers understand sleep issues in IBD and identify ways to improve care during symptom-free periods.
Clermont-FerrandAges 18–65 - NCT05874206Recruiting
Branch stent graft for fixing aorta problems in the chest
This trial tests whether a “branch” stent graft can safely repair certain problems in the descending aorta (the big blood vessel in the chest). It may help by sealing the problem while keeping blood flow to an important branch vessel in the left upper chest area.
ZurichAges 18 years+ - NCT06015620Recruiting
Health changes after mini gastric bypass surgery
This study looks at how mini gastric bypass surgery helps with obesity-related health problems and changes in body composition. It aims to see if patients experience improvements in conditions like diabetes or high blood pressure.
Bhubaneswar, OdishaAges 18–65 - NCT06042387Recruiting
Genome study across diverse populations with IBD
This study looks at the genes of people with inflammatory bowel disease (IBD) and healthy volunteers to understand why IBD affects different populations. You may join if you have Crohn's disease, ulcerative colitis, or undetermined IBD, or if you are a healthy person without any IBD history.
Toronto, OntarioAges Any age - NCT06065228Recruiting
Tracking treatment progress in children with IBD
This study looks at a new way to measure how well treatment is working in children with inflammatory bowel disease (IBD). It uses a special eye test called pupillometry, which is painless and non-invasive, to see if it can help doctors adjust treatment earlier.
Washington D.C., District of ColumbiaAges 6–21 - NCT06073873Recruiting
Safety study of ozanimod for ulcerative colitis in Korea
This study is checking the safety of ozanimod, a daily pill, for people with moderate to severe active ulcerative colitis. It looks at how well patients tolerate the medicine in real-world use in Korea.

Common questions
- Are there clinical trials for ulcer?
- Yes. Clin2 currently lists 548 recruiting ulcer 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 ulcer 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 ulcer 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.
