Recruiting studies
- NCT03901235RecruitingPhase 1/Phase 2
Stem cell injections for Crohn’s lesions that won’t heal
This study tests injections of stem cells placed directly into Crohn’s affected tissue. It may help people whose Crohn’s disease lesions have not responded to standard medicines and biologic therapies.
Liège, LiègeAges 18 years+ - NCT06663332RecruitingPhase 3
Long-term study of guselkumab in children who previously took it
This study is a long-term follow-up for children who have already finished an earlier study of guselkumab, a medicine for skin conditions like psoriasis. It looks at whether staying on the medicine continues to be safe and helpful over time.
Atlanta, GeorgiaAges 3 years+ - NCT07169123Recruiting
Salt and inflammation in Crohn's disease study
This study looks at how salt affects inflammation in people with Crohn's disease. You will have blood and urine tests to measure how your body handles sodium and inflammation.
Hamilton, OntarioAges 18–70 - NCT07724990Recruiting
Probiotic for gut health in mild-to-moderate colitis
This trial tests a specific probiotic (a type of beneficial bacteria) to see if it can help people with mild to moderate ulcerative colitis by improving the balance of gut microbes. It may be an option if you have not used many advanced treatments before.
Roma, RMAges 18–80 - NCT07710287Recruiting
Using a protein test to measure inflammation in IBD
This study looks at a protein called claudin 2 in tissue samples from people with inflammatory bowel disease (IBD). The goal is to see if it can help doctors tell whether inflammation is active or inactive. This could lead to a more accurate way to check disease activity.
San Donato Milanese, MiAges 18 years+ - NCT06997965RecruitingPhase 4
Mirikizumab for Crohn's with inflammatory strictures
This study tests a medication called mirikizumab to see if it can help people with Crohn's disease who have narrowing (strictures) in the small intestine caused by inflammation. The goal is to improve symptoms like belly pain after eating and to possibly reduce the narrowing without needing surgery.
Orlando, FloridaAges 18 years+ - NCT03183661Recruiting
Follow-up study for people previously given ALLO-ASC-CD
This study checks the long-term safety of ALLO-ASC-CD in people who already received it in an earlier phase 1 trial. It may help confirm that the treatment remains safe over time.
SeoulAges 18–65 - NCT04859088Recruiting
Biologics plus partial tube-feeding for Crohn’s disease
This study tests whether starting adalimumab along with partial enteral (tube or drink) nutrition helps control active Crohn’s disease. It may help reduce symptoms and inflammation compared with standard care alone.
Glasgow, ScotlandAges 16 years+ - NCT05169593RecruitingPhase 4
Prevent Crohn’s return after surgery: endoscopy-guided vs standard medicine
This study compares two ways to choose biologic (targeted) medicines after Crohn’s surgery to help stop Crohn’s from coming back in the bowel. It may help you avoid or delay repeat inflammation by adjusting treatment based on endoscopy findings.
Antwerp, AntwerpenAges 18–80 - NCT05469607Recruiting
Tested a device to treat Crohn’s after bowel surgery
This study looks at using a new neurotechnology-based approach (a technology that talks to the nervous system) for people with Crohn’s disease after they’ve had bowel surgery. It’s meant for patients whose new surgical connection (an anastomosis) looks normal on scope and is reachable by colonoscopy.
Melbourne, VictoriaAges 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+ - NCT05658081Recruiting
Two surgical stitch methods for Crohn’s bowel surgery
This trial compares two surgical ways of connecting the bowel in people with Crohn’s disease who need bowel resection (removal of a diseased bowel segment) and then reconnect it. If you qualify, the study may help show which method is safer or leads to better recovery.
Nanjing, JiangsuAges 16–60 - NCT05660746RecruitingPhase 2/Phase 3
Infliximab dose tailored to control Crohn’s inflammation
This trial tests a more precise way to start infliximab (a Crohn’s medicine) and adjust dosing based on how your body responds. It aims to better control Crohn’s inflammation early and keep it under control.
Los Angeles, CaliforniaAges 6–22 - NCT05974280Recruiting
Stem cell treatment for complex anal fistulas
This trial compares two types of stem cell treatments to help heal complex anal fistulas (abnormal tunnels near the anus). You may be eligible if your Crohn’s-related disease is mostly controlled and the fistula has not fully healed with standard treatments.
Nantes, NantesAges 18 years+ - NCT06089590Recruiting
I-CARE 2 study on IBD, cancer and serious infections
This study follows adults with Crohn's disease, ulcerative colitis, or unclassified IBD to better understand the links between these conditions, cancer, and serious infections. It asks you to share personal details and complete online surveys over time.
AmiensAges 18–75 - NCT06197334Recruiting
Recording stomach and gut signals with skin sensors
This study uses small sensors placed on your belly to record electrical signals from your stomach and intestines. It may help doctors better understand conditions like Crohn's disease and other digestive issues without using needles or inside-the-body tests.
Vandœuvre-lès-Nancy, CHRU de NancyAges 18 years+ - NCT06468774Recruiting
Test for gut ischemia in chronic belly artery disease
This study tests a blood marker for chronic mesenteric ischemia (poor blood flow to the gut). If it works, it could help doctors diagnose the condition faster and more easily.
Oslo, OsloAges 18 years+ - NCT05421455Recruiting
Early vs delayed surgery for Crohn’s bowel narrowing
This study compares two timing choices for surgery in people with Crohn’s disease who have bowel narrowing (strictures) causing blockage symptoms. The goal is to see whether operating earlier leads to better control of symptoms and inflammation when other treatments haven’t worked.
Nanjing, JiangsuAges 18–60 - NCT06495658Recruiting
Prebiotics for ulcerative colitis symptoms
This trial tests whether a prebiotic supplement can improve symptoms of ulcerative colitis. It may be a good option for people with active symptoms who are already on stable medications.
Los Angeles, CaliforniaAges 18–85 - NCT06516341Recruiting
Predicting bowel recurrence after surgery for chronic inflammation
This study follows patients with Crohn's disease or ulcerative colitis to see how their intestine heals after surgery. It looks for signs that can predict whether inflammation will return or complications will happen.
Milan, ItalyAges 18–69 - NCT06670638Recruiting
New test for crohn's disease in people with a permanent ileostomy
This study aims to develop a new way to measure inflammation and symptoms in people with Crohn's disease who have a permanent ileostomy. Participants will undergo a routine ileoscopy and answer questions to help create better tools for future clinical trials.
Rochester, MinnesotaAges 18 years+ - NCT06698601Recruiting
Wild blueberries for colitis inflammation
This study tests whether eating wild blueberries can help reduce inflammation in people with Crohn's disease or ulcerative colitis. You would eat wild blueberries during your hospital stay and have a colonoscopy to see how your gut is doing.
Bamberg, BavariaAges 18 years+ - NCT06862843Recruiting
Family eating habits and chronic inflammation study
This study looks at how eating habits and family health history relate to chronic inflammatory conditions like Crohn's disease, ulcerative colitis, and juvenile idiopathic arthritis. It aims to understand these links by studying families with a child or adult affected by these conditions, as well as healthy families.

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.
