Recruiting studies
- NCT06937099RecruitingPhase 3
Testing two drugs for Crohn's with weight issues
This trial tests two study drugs, mirikizumab and tirzepatide, in people with moderate to severe Crohn's disease who also have overweight or obesity. The goal is to see if these treatments can help control Crohn's symptoms and inflammation.

Stem cell therapy for Crohn's fistula healing
This trial tests if a special stem cell treatment (called DB-3Q bmMSC-EVs) can help heal fistulas caused by Crohn's disease. It's for people who have already tried other treatments and still have actively draining fistulas.
Aurora, ColoradoAges 18–75 - NCT05039411RecruitingPhase 1
Cord stem cell treatment for Crohn’s perianal fistulas
This Phase 1 study tests whether donor umbilical cord stem cells are safe for treating fistulas (abnormal tunnels) near the anus in people with Crohn’s disease. It’s mainly looking at safety, and it may help some people’s symptoms if the approach is workable.
Kuala LumpurAges 18 years+ - NCT07316621Recruiting
Crohn's disease risk study for close relatives
This study follows close family members of people with Crohn's disease to see if they develop early signs of the condition. It uses blood tests and checkups to detect Crohn's earlier.
RomaAges 16–35 - NCT06216899Recruiting
Liquid diet study for new Crohn's in kids and teens
This study tests a special liquid diet (smoothie) to treat newly diagnosed Crohn's disease in children and young adults. It aims to understand how the diet works and if it can help reduce inflammation.
Philadelphia, PennsylvaniaAges 8–21 - NCT07541261Recruiting
Real-World Study of Guselkumab for Ulcerative Colitis and Crohn's Disease
This study tracks how guselkumab (a biologic medication that reduces inflammation) works in patients with moderate-to-severe ulcerative colitis or Crohn's disease in Saudi Arabia. Researchers want to understand how the medication helps patients in everyday clinical practice, not in a controlled research setting.
JeddahAges 18 years+ - NCT07095634Enrolling by invitation
Heart risk study for Crohn's and colitis patients
This study looks at heart health in people with Crohn's disease or ulcerative colitis. It aims to understand the risk of heart problems over 2 years.
San Donato Milanese, MilanAges 16 years+ - NCT07191106Recruiting
Remote exercise program for inflammatory bowel disease
This study tests whether a remote exercise program, done at home using an app, can improve quality of life for people with inflammatory bowel disease (IBD). It may help if you are motivated to start a gentle physical activity routine and have internet access.
MontfermeilAges 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 - 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 - NCT06758024Recruiting
Optimizing infliximab for inflammatory bowel disease
This trial tests whether closely monitoring and adjusting infliximab (a biologic medicine) can help people hospitalized with a moderate-to-severe flare of Crohn's disease, ulcerative colitis, or unclassified inflammatory bowel disease who haven't gotten better with IV steroids. The goal is to improve treatment response and outcomes.
SantiagoAges 18–75 - NCT06722456Enrolling by invitation
Better ways to detect active IBD
This study tests non-invasive tools to find active inflammation in people with Crohn's disease or ulcerative colitis. You may need to give extra stool samples before your colonoscopy and calprotectin test.
Sherbrooke, QuebecAges 18 years+ - NCT06604260RecruitingPhase 2
PET scan to measure inflammation in Crohn's and colitis
This trial uses a special PET scan called FAPi-PET to look for inflammation and scarring in the gut. It may help doctors better understand your condition and guide treatment.
Amsterdam, North HollandAges 18 years+ - NCT03167437RecruitingPhase 1/Phase 2
Vorinostat for uncontrolled Crohn’s or ulcerative colitis
This early-phase study tests vorinostat to reduce gut inflammation in people with moderate-to-severe Crohn’s disease, ulcerative colitis, or certain colitis patterns linked to chronic granulomatous disease (CGD). It also looks at whether the study’s consent process is clear and understood before starting treatment.
Bethesda, MarylandAges 18–65 - NCT04331639Recruiting
High-dose vitamin D for kids with IBD on biologic therapy
This trial studies whether giving a higher dose of vitamin D3 helps children and teens with inflammatory bowel disease (Crohn’s or ulcerative colitis) who have low vitamin D levels. Participants are already on biologic medicines and will be treated while monitoring blood (and safety) related to vitamin D.
Boston, MassachusettsAges 5–25 - NCT06252493Recruiting
PET/MR scan for Crohn's disease scar tissue
This study is testing a new imaging method that uses a special PET/MR scan to see how active Crohn's disease is in your bowel. The scan uses a harmless radioactive tracer that attaches to scar tissue, which may help doctors better understand the disease and guide treatment.
Charlestown, MassachusettsAges 18–99 - NCT06651281RecruitingPhase 3
Long-term safety and effectiveness of tulisokibart for Crohn's or colitis
This study gives tulisokibart to people who already took part in an earlier trial for Crohn's disease or ulcerative colitis and are still benefiting from it. The goal is to see how safe and effective the medicine is over a longer period.
Bristol, ConnecticutAges Any age - NCT06734780Recruiting
Vaping and Crohn's disease return after surgery
This study looks at how vaping versus smoking tobacco affects the return of Crohn's disease after surgery. It may help doctors understand which habit is safer for people who have had their intestine reconnected.
Milan, MichiganAges 18 years+ - NCT04970446RecruitingPhase 1/Phase 2
Fecal transplant to restore gut microbes in Crohn’s
This Phase 1/2 study tests whether a fecal microbiome transplant (FMT) can reduce active inflammation in people with Crohn’s disease. It’s designed for people who currently have signs of active bowel inflammation and can attend regular procedure visits.
Melbourne, VictoriaAges 18–70 - 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.

Tissue repair study in IBD using organoid technology
This study collects tissue samples from people with Crohn's disease or ulcerative colitis during routine colonoscopy or surgery to grow mini-organs (organoids) in the lab. The goal is to learn how the gut heals itself, which could lead to better treatments.
MarseilleAges 18 years+ - NCT04191395Recruiting
Study of treatments for long-term inflammatory diseases

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.
