Recruiting studies
- NCT07198113Recruiting
Comparing newer treatments for pediatric inflammatory bowel disease
This study is for children and teens with inflammatory bowel disease (Crohn's, colitis, or indeterminate) whose previous anti-TNF medicine stopped working. It compares several newer treatments to see which works best.

Stool transplant to maintain Crohn’s remission after stopping anti-TNF
This Phase 3 study tests whether transplanting stool bacteria can help people with Crohn’s stay in remission after they stop an anti-TNF medicine. It may help some patients who are currently doing well but need to come off anti-TNF treatment.
ParisAges 18–74 - NCT05040464RecruitingPhase 3
Azathioprine or methotrexate added to adalimumab for Crohn’s
This trial compares two medicine options (azathioprine vs methotrexate) when added to adalimumab to treat active Crohn’s disease. It may help determine which add-on works better for people whose Crohn’s is still active despite standard treatments or who can’t take them.
AmiensAges 18 years+ - NCT07456566Recruiting
Self-management help for inflammatory bowel disease
This trial tests a self-management program for people with active Crohn's disease or ulcerative colitis. It aims to improve quality of life by helping you better manage your condition.
Ann Arbor, MichiganAges 18 years+ - NCT03589183Recruiting
Gut microbiome study for ulcerative colitis and Crohn disease
This study looks at how changes in gut bacteria (the microbiome) relate to inflammatory bowel disease, including ulcerative colitis and Crohn disease. It may help researchers understand what might improve symptoms or disease control.
SeoulAges Any age - NCT06892990Recruiting
Better imaging for inflammation in bowel disease
This trial tests a new imaging technique that may help doctors see inflammation more clearly during colonoscopy in people with Crohn's disease or ulcerative colitis. The technique is called Texture and Color Enhancement Imaging (TXI).
Ulm, Baden-WurttembergAges 18 years+ - NCT05645055Recruiting
Biologic treatment for bowel narrowing in Crohn’s disease
This trial studies biologic medicines to treat Crohn’s disease that causes bowel narrowing (“strictures”) without needing immediate surgery. It may help reduce symptoms and complications by targeting the immune-driven inflammation behind the narrowing.
Nanjing, JiangsuAges 16–65 - NCT06581328RecruitingPhase 4
Study of vedolizumab for ulcerative colitis or Crohn's disease
This study tests the drug vedolizumab in adults with moderate to severe ulcerative colitis or Crohn's disease. It aims to see how well the medicine works in a community (non-hospital) setting.
Birmingham, AlabamaAges 18–80 - NCT07073079Recruiting
Study of upadacitinib and risankizumab for Crohn's after first therapy
This study tests two oral/ injectable medicines (upadacitinib and risankizumab) in adults with moderate-to-severe Crohn's who have already tried a TNF-blocker. It aims to see how well these treatments work in everyday practice.
Castellana Grotte, BariAges 18 years+ - NCT04330846Recruiting
Study of new narrowing in Crohn’s treated with two approaches
This study looks at treatments for a new (de novo) narrow area in the bowel from Crohn’s disease. It aims to see which treatment works better at relieving blockage-type symptoms for the safest, most effective option.
Badalona, BarcelonaAges 18–80 - NCT06579443Recruiting
Robotic surgery study for inflammatory bowel disease
This study looks at how well robotic surgery works for people with inflammatory bowel disease. It aims to help surgeons learn and improve outcomes for patients like you.
Coventry, West MidlandsAges 18 years+ - NCT07166588Enrolling by invitation
Precision medicine study for inflammatory bowel disease
This study looks at using precision medicine to treat inflammatory bowel disease (IBD) in people who are newly diagnosed or already being monitored. It aims to find better ways to manage the condition.
Seoul, SeoulAges 10 years+ - NCT03816345RecruitingPhase 1
Nivolumab for advanced cancer with autoimmune conditions
This Phase 1 study tests nivolumab, an immunotherapy “anti-cancer accelerator,” in people with advanced cancer who also have an autoimmune disorder. It aims to see if nivolumab can be given safely and whether it may help shrink or control cancer.
Birmingham, AlabamaAges 18 years+ - NCT04973423Recruiting
Testing extra check-ins for Crohn’s using stool tests and MRI
This study checks whether adding an extra, cross-body “transmural” evaluation (looking at inflammation throughout the bowel) improves care for adults with Crohn’s who are starting or receiving biologic (biotherapy) treatment. It uses close follow-up with stool calprotectin (a marker of gut inflammation) to see if this approach helps control inflammation.
AmiensAges 18 years+ - NCT06719622Enrolling by invitationPhase 2/Phase 3
Budesonide for Crohn's in the upper gut
This trial tests a budesonide liquid that targets inflammation in the esophagus, stomach, and duodenum (upper digestive tract) in children with Crohn's disease. It aims to see if this treatment can reduce inflammation in those areas without strong side effects.
KrakowAges 6–18 - NCT06995170Recruiting
Polyamines and IBD progression study
This study looks at how certain natural chemicals called polyamines relate to the activity of inflammatory bowel disease (IBD). It aims to understand if these chemicals can help predict disease progression.
Xi'an, ShaanxiAges 18–65 - NCT06241170Recruiting
Surgical margin study for Crohn's disease recurrence
This trial tests a specific way of cutting the bowel during surgery for Crohn's disease to see if it lowers the chance of the disease coming back. It is for people with Crohn's in the ileocecal area who are having their first surgery to remove that section.
Guangzhou, GuangdongAges 14–65 - NCT07616687RecruitingPhase 4
Testing guselkumab to improve Crohn's disease control
This study tests whether guselkumab, a newer biologic medication, can better control active Crohn's disease symptoms and inflammation. You'll receive the medication and be monitored closely to see how well it works for you.

Study of new childhood IBD and tracking safety
This trial collects information from children who are newly diagnosed with inflammatory bowel disease (IBD) and follows them to understand safety in real life. It may help doctors improve early diagnosis and treatment planning for kids with IBD.
RotterdamAges birth–19 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+ - NCT06453720Recruiting
Predicting Crohn's treatment success with gut bacteria
This study analyzes your gut bacteria to see if it can predict how well you will respond to Crohn's disease treatments. If you are having a colonoscopy for routine care, you may be eligible.

Common questions
- Are there clinical trials for crohn’s disease?
- Yes. Clin2 currently lists 334 recruiting crohn’s 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 crohn’s 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 crohn’s 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.
