Recruiting studies
- NCT06372613Recruiting
LRG protein and ulcerative colitis remission
This study looks at a protein called LRG in your blood or tissue to see if it can tell if your ulcerative colitis is in remission (quiet or not active). This might help doctors better monitor and treat UC in the future.
KomaganeAges 20–90 - NCT06359808Recruiting
Sleep Problems in Ulcerative Colitis Patients
This study looks at sleep problems in people with ulcerative colitis (a type of inflammatory bowel disease). It aims to understand how sleep affects your condition and may help find better ways to manage both.
Xi'an, ShaanxiAges 18–65 - NCT06335160Recruiting
Mebendazole for mild to moderate ulcerative colitis
This study tests adding a medicine called mebendazole (normally used for parasites) to standard mesalamine treatment for people with mild or moderate ulcerative colitis. The goal is to see if it helps control inflammation better than mesalamine alone.
TantaAges 18–75 - NCT06337695RecruitingPhase 2/Phase 3
Preventing immunotherapy-related diarrhea in advanced cancer
This study tests whether vedolizumab, a drug that reduces gut inflammation, can prevent diarrhea caused by immunotherapy (a type of cancer treatment). It is for adults with advanced melanoma, lung, or kidney cancer who have a stool marker of inflammation early in treatment.
Calgary, AlbertaAges 18 years+ - NCT06315179Recruiting
Spatial gene study for inflammatory bowel disease
This study looks at tissue samples from people with suspected Crohn's disease, ulcerative colitis, or indeterminate colitis. The goal is to understand these conditions better and may lead to improved treatments.
Seattle, WashingtonAges 6–21 - NCT04121806Recruiting
Diet plan for active ulcerative colitis flare-ups
This trial studies whether a specific diet can improve symptoms and reduce inflammation during an active flare of ulcerative colitis. You may be eligible if you have documented active disease and can follow the study diet and medication rules.
Toronto, OntarioAges 18–75 - NCT06228352Recruiting
Bile acids and gut bacteria in C. difficile with ulcerative colitis
This study looks at how bile acids and gut bacteria relate to C. difficile infection in children with ulcerative colitis. It aims to find better ways to predict and treat these infections.
ParisAges Up to 17 years - NCT06206707Recruiting
FMT for Diarrhea and Colitis After Immunotherapy
This trial tests whether a treatment called fecal microbiota transplant (FMT) — transferring healthy gut bacteria — can help relieve diarrhea and colitis caused by immunotherapy drugs. If you have melanoma or kidney cancer and are experiencing diarrhea after immunotherapy, this study may offer a new option.
Aarhus NAges 18 years+ - NCT05428345Recruiting
Shot of vedolizumab skin injection for active bowel inflammation
This study tests whether a weekly/regular skin injection version of vedolizumab can help adults with moderate to severe ulcerative colitis or Crohn’s disease who did not fully respond to other treatments or TNF blockers. It may help by moving you from an intravenous (IV) infusion to a self/clinic injection option.
Goyang-si, Gyeonggi-doAges 18 years+ - NCT06095128RecruitingPhase 4
Combination therapy for ulcerative colitis
This study tests two drugs together, vedolizumab and tofacitinib, to see if they are more effective than either alone in treating moderate to severe ulcerative colitis. It may be an option if other treatments have not worked well for you.
Dothan, AlabamaAges 18–65 - NCT06100289RecruitingPhase 3
Study of vedolizumab for kids with ulcerative colitis or Crohn's disease
This trial tests vedolizumab, a biologic medicine that reduces inflammation, in children and teenagers who have moderate to severe ulcerative colitis or Crohn's disease and have not responded well to other treatments.
Phoenix, ArizonaAges 2–17 - NCT06095596Recruiting
Combining vedolizumab and upadacitinib for ulcerative colitis
This trial tests whether two medications, vedolizumab (a biologic given by IV) and upadacitinib (a pill), work together to help people with moderate to severe ulcerative colitis. The goal is to see if this combination is safe and effective for controlling symptoms and healing the colon.
Guangzhou, GuangdongAges 18 years+ - NCT06071312RecruitingPhase 1/Phase 2
Fecal transplant for C. diff and ulcerative colitis
This trial tests whether one or multiple fecal transplants from a healthy donor can help treat both a recurring C. diff infection and active ulcerative colitis. It aims to find the best schedule for the procedure.
RomeAges 18–75 - NCT05987852Recruiting
Hyperbaric oxygen therapy for ulcerative colitis flare
This trial tests if hyperbaric oxygen therapy (breathing pure oxygen in a special chamber) can help people hospitalized with a moderate to severe ulcerative colitis flare get better faster. You will receive the therapy along with standard steroid treatment.
Birmingham, AlabamaAges 18–85 - NCT05953402Recruiting
Testing ozanimod use in pregnant people with ulcerative colitis
This trial studies how ozanimod affects pregnant people with ulcerative colitis and their babies. It may help doctors understand safety and outcomes when this medicine is used during pregnancy and after birth.
Wilmington, North CarolinaAges Any age - NCT05895981Recruiting
Sacral nerve stimulation for ulcerative colitis symptoms
This trial tests whether sacral nerve stimulation—a device that sends small electrical signals near nerves in the lower back—can be safe and helpful for ulcerative colitis. It is meant for people whose ulcerative colitis has not improved enough with medicines.
Xi'an, ShaanxiAges 18 years+ - NCT05867329RecruitingPhase 4
Comparing treatments for severe ulcerative colitis flare-ups
This study compares different sequences of medicines for treating severe ulcerative colitis flares in the hospital. It aims to find the best way to get your symptoms under control and help you feel better faster.
Ann Arbor, MichiganAges 18–75 - NCT05739864RecruitingPhase 1/Phase 2
Test of donor gut bacteria for ulcerative colitis
This early-stage study tests whether a one-time transfer of “donor gut bacteria” can improve ulcerative colitis. It’s designed for people with mild to moderate ulcerative colitis who are stable on maintenance treatment.
Rome, LazioAges 18–75 - 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+ - NCT05679622Recruiting
Stool transplant study for children with mild to moderate ulcerative colitis
This trial studies whether transferring healthy stool bacteria into the gut (fecal microbiota transplantation, or FMT) can improve symptoms in children with ulcerative colitis. It may help by changing gut bacteria, especially for children who are newly diagnosed or who didn’t respond to standard treatments.
WuhanAges 2–16 - NCT05442567RecruitingPhase 3
Vedolizumab study for kids with ulcerative colitis or Crohn’s
This Phase 3 study tests whether vedolizumab can help children with ulcerative colitis (UC) or Crohn’s disease (CD) who improved on earlier treatment. It focuses on kids who can stay off steroid medicines and follow study visits and safety rules.
Mobile, AlabamaAges 2 years+ - NCT05333471RecruitingPhase 1/Phase 2

Common questions
- Are there clinical trials for colitis?
- Yes. Clin2 currently lists 308 recruiting colitis 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 colitis 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 colitis 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.
