- NCT07644117Recruiting
Personalized Anti-TNF Treatment for Inflammatory Bowel Disease
This trial tests a personalized approach to starting anti-TNF therapy—a common treatment for inflammatory bowel disease (IBD)—in patients who have never taken it before. The goal is to help doctors choose the right anti-TNF medication and dose based on each patient's individual characteristics.
Tel AvivAges 18 years+ - NCT07113795Enrolling by invitationEarly Phase 1
Chinese medicine and stem cells for Crohn's fistula
This trial tests a new approach that combines traditional Chinese medicine with stem cells to treat complex anal fistulas caused by Crohn's disease. It may help people whose Crohn's is not very active and who have not had major fistula surgery before.
Nanjing, JiangsuAges 18–60 - 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+ - NCT06918808RecruitingPhase 2
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 - 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 - 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 - 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 - NCT06180382RecruitingPhase 4
Comparing vedolizumab to higher-dose adalimumab for Crohn's disease
This trial tests whether switching to vedolizumab works better than increasing your adalimumab dose if your Crohn's symptoms or inflammation are coming back despite treatment. It aims to find the best next step for people whose condition is no longer well-controlled.
Le Kremlin-Bicêtre, PARISAges 18 years+ - NCT06113913RecruitingPhase 4
Switching from IV to under-the-skin infliximab after dose increase
This study tests if switching from a high-dose infliximab IV infusion to a daily or weekly injection under the skin works just as well. It is for people with inflammatory bowel disease who are already stable on IV infliximab.
Ghent, Oost-VlaanderenAges 18 years+ - 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+ - NCT04997733RecruitingPhase 3
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 - 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+ - 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 - NCT07582731Recruiting
Video Education to Improve Colonoscopy Preparation in IBD
This study tests whether personalized video lessons tailored to your specific type of inflammatory bowel disease (Crohn's disease or ulcerative colitis) help you prepare better for a colonoscopy. Better preparation means clearer pictures during the procedure, which helps doctors see your disease more accurately.
Beijing, BeijingBeijingAges 18–75 - NCT07582458RecruitingPhase 2/Phase 3
Modafinil for Fatigue in Controlled Inflammatory Bowel Disease
This trial tests whether modafinil (a wakefulness-promoting medication) can reduce severe fatigue in people with inflammatory bowel disease (IBD) whose disease is well-controlled. If you have persistent exhaustion despite your IBD being stable, this study may help determine if this medication works for you.
Arnhem, GelderlandAges 18–75 - NCT03816345RecruitingPhase 1
Nivolumab for advanced cancer with autoimmune disease
This trial tests whether the immunotherapy drug nivolumab can safely treat advanced cancer in people who also have an autoimmune disease like rheumatoid arthritis, lupus, or multiple sclerosis. It aims to find out if the drug may help control cancer while managing their autoimmune condition.
Birmingham, AlabamaAges 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 - 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+ - 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 - NCT06581328RecruitingPhase 4
Study of vedolizumab for ulcerative colitis or Crohn's disease
This study tests a medication called vedolizumab for people with moderate to severe ulcerative colitis or Crohn's disease. The goal is to see how well it works in a regular community setting, and it may help control symptoms if other treatments haven't worked.
Birmingham, AlabamaAges 18–80 - NCT07616687RecruitingPhase 4
Testing guselkumab to improve Crohn's disease control
