This large study tests whether guselkumab, an injected drug, can control symptoms and heal the gut lining in people with moderate to severe Crohn's disease. About 1,400 participants will receive guselkumab, an existing treatment (ustekinumab), or a placebo. The goal is to see if …

This study tests a drug called guselkumab in 120 people with Crohn's disease to see if it can heal all layers of the digestive tract. The main goal is to check healing using an MRI scan after 48 weeks of treatment. Participants must have active Crohn's disease and will receive th…

This study tests an experimental drug called AZD7798 in 24 adults with active Crohn's disease who have an ileostomy. The goal is to see if the drug is safe and can help repair the gut lining compared to a placebo. Participants will be monitored for side effects and changes in the…

This study looks at the long-term safety and effectiveness of balinatunfib, an oral tablet, in adults with Crohn's disease or ulcerative colitis. Participants have already completed a one-year treatment in a previous study. The trial will last up to 107 weeks and includes both do…

This study aimed to test whether injecting stem cells from a donor's bone marrow into the pouch (a surgically created internal reservoir) could safely treat pouchitis that hadn't improved with antibiotics or other drugs. The trial was planned for 12 adults aged 18-75 in the U.S.,…

This study tests whether a fecal transplant (FMT) can safely and effectively treat recurrent C. difficile infections in children, including those with inflammatory bowel disease (IBD). Researchers will give FMT to 250 children aged 3-21 and track whether the infection comes back.…

This study aimed to test whether injecting donor stem cells directly into fistulas could safely help heal them in people with Crohn's disease who have an ileal pouch. The trial was withdrawn before any participants were enrolled, so no results are available. The approach was expe…

This phase 3 trial tests whether upadacitinib (RINVOQ), a daily oral medication, can help adults with Crohn's disease maintain remission after initial treatment. About 747 participants who responded to upadacitinib in earlier studies will receive either the drug or a placebo. The…

This early-stage trial aimed to see if injecting donor stem cells around fistulas (abnormal tunnels) could safely help heal them in people with Crohn's disease. The study planned to enroll 20 adults with complex or multiple fistulas. However, the trial was withdrawn before any pa…

This study is a survey of 335 people with moderate to severe Crohn's disease who are taking Entyvio (vedolizumab) as part of their regular care. The goal is to see how safe and effective the drug is over the long term in everyday medical practice. Researchers will track side effe…

This study looks at how well and how safely the drug mirikizumab works over the long term for people with Crohn's disease. About 996 adults who were in earlier mirikizumab studies will continue treatment. The goal is to see if the drug can keep the gut healed and symptoms under c…

This study tests whether two special diets—the specific carbohydrate diet or an elemental (liquid) diet—can help people with active Crohn's disease or ulcerative colitis feel better. Forty adults will choose one diet and follow it for 6 weeks, while researchers track symptoms, in…

This early-phase trial is testing whether an oral herbal formula called E-B-FAHF-2 is safe and tolerable for people with mild-to-moderate Crohn's disease. Only 7 adults will take either the herbal capsule or a placebo for a short time. The goal is to see if it reduces inflammatio…

This phase 3 trial is testing whether risankizumab (Skyrizi) can help people with moderate-to-severe Crohn's disease. About 289 adults will receive either the drug or a placebo as a shot under the skin for up to 24 weeks, followed by an open-label extension. The goal is to see if…

This study tests whether personalized exercise coaching can reduce fatigue and improve quality of life in children with inflammatory bowel disease (IBD). Seventy children will be split into two groups based on their current exercise habits and will follow a 24-week program with a…

This study looks at how diet, genetics, and gut bacteria work together to cause digestive problems like IBS, IBD, and celiac disease. Researchers will follow about 4,000 adults with and without these conditions to find patterns. The goal is to understand why some people get sick …

This study follows nearly 5,000 children with Crohn's disease, ulcerative colitis, or indeterminate colitis to monitor the long-term safety of their treatments, including the drug infliximab. Researchers collect information on side effects, disease activity, and quality of life o…

This study observes 1006 adults with ulcerative colitis or Crohn's disease in Brazil who are taking or have taken vedolizumab. Researchers will look at how long patients stay on the drug and what other treatments they used before. No new treatment is given—this is just a review o…

This pilot study is testing whether a deep learning algorithm can identify and score inflamed segments of the terminal ileum in MRI scans of people with Crohn's disease. Researchers will use 226 anonymized MRI scans, with radiologists first marking normal and abnormal areas. The …

This 5-year observational study is following 15,000 adults and children with inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, in real-world clinics. Researchers are collecting data on disease patterns, treatment use, and patient outcomes to bett…

This observational study is following up to 500,000 adults with chronic gastrointestinal diseases like Crohn's disease, ulcerative colitis, and eosinophilic GI disease. Researchers will collect data from electronic health records and patient reports to understand how these condit…

This study looks at how a tool called CDPATH can help predict the risk of serious complications in people with Crohn's disease within the next three years. About 200 adults with Crohn's will use the tool to learn their risk level (low, medium, or high) and discuss treatment optio…

This registry is following over 2,200 adults with inflammatory bowel disease (IBD) across North America to see how approved treatments work in everyday practice. Researchers are collecting data on disease patterns, complications, and patient outcomes. The goal is to better unders…
