Recruiting studies
- NCT07314606Recruiting
Diet plus infliximab for kids with Crohn’s
This study tests if a special diet (called CDED) combined with infliximab (a biologic drug) is more effective than infliximab alone for children with newly diagnosed or relapsed moderate-to-severe Crohn’s disease. It aims to improve gut healing and reduce inflammation.
Vancouver, British ColumbiaAges 9–17 - NCT01793831Recruiting
Fecal transplant study for people with Crohn’s disease
This study tests whether a standardized stool-based treatment (fecal microbiota transplantation) can help people with Crohn’s disease. You may qualify if your Crohn’s diagnosis has been stable and you’re willing to receive the fecal transplant.
Huai'an, JiangsuAges Any age - NCT07652632Recruiting
Regenerative endoscopy for hard-to-treat Crohn's fistulas
This trial tests a new, less invasive procedure called regenerative endoscopy to repair complex fistulas in people with Crohn's disease. It's for those who haven't gotten better with standard treatments like biologics or surgery.
Hyderabad, TelanganaAges 18–65 - NCT07077746RecruitingPhase 2
Stem cells for Crohn's disease
This trial tests whether a type of stem cell called HB-adMSCs can help treat Crohn's disease. It is for adults with mild to moderate Crohn's who have certain signs of inflammation in their blood and recent imaging of their condition.
Sugar Land, TexasAges 18–65 - NCT07483099RecruitingPhase 2
Study of two drugs for Crohn's disease
This trial tests if taking a new drug (LY4395089) with mirikizumab works better than mirikizumab alone for adults with Crohn's disease. It also looks at the safety of these treatments.
Scottsdale, ArizonaAges 18–80 - NCT04263831RecruitingPhase 1/Phase 2
Low-dose IL-2 to treat Crohn’s disease flare-ups
This trial tests a low dose of IL-2 to reduce inflammation and help control Crohn’s disease symptoms. It’s for people whose Crohn’s disease hasn’t responded to at least one standard treatment or who need steroids to stay under control.
Boston, MassachusettsAges 12–80 - NCT07499232RecruitingPhase 3
Guselkumab vs Risankizumab for Crohn's disease
This trial compares two drugs, guselkumab and risankizumab, to see which works better for people with moderate-to-severe Crohn's disease. Both are given as injections and aim to reduce inflammation in the gut.
Dothan, AlabamaAges 18 years+ - NCT07577843RecruitingPhase 3
Testing JNJ-78934804 for moderate to severe Crohn's disease
This study tests a new drug called JNJ-78934804 for people with moderate to severe Crohn's disease who have not responded well to or can't tolerate current treatments. The goal is to see if this drug can reduce inflammation and symptoms in the digestive tract.
Anaheim, CaliforniaAges 18 years+ - NCT07196722RecruitingPhase 2/Phase 3
Testing icotrokinra for moderate to severe Crohn's disease
This study tests a new medicine called icotrokinra for people with moderate to severe Crohn's disease who have not responded well to other treatments. It aims to see if icotrokinra can help reduce symptoms and improve gut health.
Chandler, ArizonaAges 18 years+ - NCT07471438Recruiting
MRI comparison for Crohn's disease activity in the ileum
This trial compares two types of MRI scans to see how well they detect inflammation in the small intestine of people with Crohn's disease. It aims to find the best way to assess disease activity without invasive procedures.
AmiensAges Any age - NCT03915262Recruiting
Active Crohn’s patients with possible pancreas enzyme problems
This study looks at how often people with active Crohn’s disease also have trouble digesting food because the pancreas may not release enough enzymes (exocrine pancreatic insufficiency). It may help doctors better recognize this hidden problem in people whose Crohn’s is currently active.
Pierre-BéniteAges 18 years+ - NCT03983473Recruiting
Testing stool samples to find gut bacteria markers in inflammatory arthritis
This study looks at stool (poop) samples to see whether gut bacteria patterns can help identify certain inflammatory arthritis conditions in people who have Crohn’s disease or axial spondyloarthritis. It’s mainly about matching stool “biomarkers” to diagnoses, which may help doctors recognize these conditions more accurately in the future.
Nancy, LorraineAges 18 years+ - NCT04192825Recruiting
Crohn’s anal drainage care study
This trial studies different care and management approaches for people with Crohn’s disease who have an anal infection or drainage area and are planning a drainage procedure. It may help improve how care is planned around the drainage procedure and follow-up.
RennesAges 18 years+ - NCT04224558RecruitingPhase 1/Phase 2
Stem cell transplant for hard-to-control Crohn’s disease
This early-phase study tests whether a stem cell transplant can improve Crohn’s disease in teens and young adults whose disease is active and not responding to standard medicines. It may help some people who are not doing well despite several prior treatments, but it also involves intensive study procedures and safety checks.
Los Angeles, CaliforniaAges 13–28 - NCT04637438Recruiting
Fecal transplant for Crohn’s around the small and large bowel
This trial studies fecal microbiota transplantation (a transplant of beneficial gut bacteria from a donor) to help people with Crohn’s disease that is causing narrowing (strictures) and/or abnormal tunnels (fistulas) and who need bowel surgery. You may qualify if you’re an adult, planning ileal/ileocecal surgery, and can complete the colonoscopy while not on certain gut-altering medicines.
TampereAges 18–120 - NCT04946448Recruiting
Test a Crohn’s diet and biologic medicine combination
This study tests whether combining a specific diet with biologic medicines can reduce active inflammation and symptoms of Crohn’s disease. It may help people who still have active disease in the bowel despite prior care.
LeuvenAges 18–80 - NCT05043870RecruitingPhase 4
Testing medicines that calm the immune system in kids with Crohn’s
This trial studies a combination of immune-suppressing treatments for children with Crohn’s disease that is not well controlled. It may help reduce inflammation and improve symptoms if you meet the study’s disease-activity and safety requirements.
Shanghai, Shanghai MunicipalityAges 6–18 - NCT05321758Recruiting
Stool transplant as first treatment for kids with Crohn’s
This study tests whether transferring healthy gut bacteria from stool into the colon can work as a first treatment for children newly diagnosed with mild-to-moderate Crohn’s disease. It may help reduce inflammation and improve symptoms, and it requires regular colonoscopy to monitor progress.
Wuhan, HubeiAges 2–16 - NCT05387031Recruiting
Ustekinumab for painful Crohn’s bowel narrowing
This trial tests ustekinumab, a medicine that calms immune inflammation, to see if it can improve symptoms in people with Crohn’s disease that causes bowel narrowing. It may help if your Crohn’s symptoms come from strictures (narrowed areas) seen on scans or endoscopy.
Beijing, Beijing MunicipalityAges 18–65 - NCT05552287RecruitingPhase 4
Infliximab drug levels in children with Crohn’s disease
This study measures how infliximab (a medicine that calms immune inflammation) moves through the body in children with Crohn’s disease. It mainly helps doctors understand dosing and drug levels, especially when treatment is newly starting.
RotterdamAges 1–15 - NCT05578235Recruiting
Surgery for Crohn’s: hand-sewn vs stapled bowel connection
This trial compares two ways of reconnecting the bowel after removing diseased intestine in people with Crohn’s disease. The goal is to see which method works better for healing and short- and longer-term outcomes.
Almere Stad, FlevolandAges 16 years+ - NCT05781152RecruitingPhase 4
Testing how new Crohn’s imaging and scopes predict outcomes
This study follows children newly diagnosed with Crohn’s disease to see how results from scans and endoscopy (camera scope) relate to outcomes over the first year. It may help doctors choose better early treatment plans and monitor children more effectively.

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.
