JenaAges 6–18 - NCT03589183Recruiting
Gut microbiome study for ulcerative colitis and Crohn disease
This study looks at how changes in gut bacteria (the microbiome) relate to inflammatory bowel disease, including ulcerative colitis and Crohn disease. It may help researchers understand what might improve symptoms or disease control.
SeoulAges Any age - NCT03809728Recruiting
Finding blood tests linked to outcomes in Crohn’s and colitis
This study looks for “biomarkers” (lab markers, like substances in blood or tissue) that may predict how Crohn’s disease or ulcerative colitis will go and how patients may respond. It may help doctors choose better monitoring or treatments in the future.
Vandœuvre-lès-NancyAges 18 years+ - NCT03813862Recruiting
Study tracking medicines from clinic records
This is an observational study that collects information about what medicines patients receive. It uses data already recorded in participating clinics’ computer health records to better understand medication use over time.
Durham, North CarolinaAges birth+ - 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 - 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 - NCT05185609Recruiting
Tests anal function in people with inflammatory bowel disease
This study checks how well the anal area works in people with inflammatory bowel disease (IBD), even when your bowel disease is “in remission” but you may still have symptoms. It may help doctors better understand the cause of ongoing problems and guide future care.
ÖrebroAges 18–65 - 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 - 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.
Toronto, OntarioAges Any age - 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 - NCT06502873Recruiting
Study of colon samples in IBD and healthy people
This study is gathering information from people with active Crohn's disease or ulcerative colitis, and from people without IBD. Researchers will look at samples from the colon to learn more about these conditions.
LiègeAges 18 years+ - NCT06548399Recruiting
Bacteria study for IBD patients with ongoing abdominal pain
This study looks at bacteria in your gut that may produce chemicals linked to ongoing pain in Crohn's disease or ulcerative colitis, even when the disease itself is not very active. Researchers want to understand why some people still have moderate to severe abdominal pain even after their inflammation has calmed down.
Hamilton, OntarioAges 18–70 - 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+ - NCT06756100Recruiting
Early inflammatory bowel disease study
This trial looks at early signs of inflammatory bowel disease (IBD) in adults who have had stomach or bowel symptoms for at least 3 weeks. It aims to understand how the disease progresses.
SantiagoAges 18–100 - 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 - NCT06780683Recruiting
Testing upadacitinib for inflammatory bowel disease
This study tests a medication called upadacitinib for people with inflammatory bowel disease (ulcerative colitis or Crohn's). The goal is to see how well it works and if it's safe.
Guangzhou, GuangdongAges Any age - NCT06805890Recruiting
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+ - NCT06814600Recruiting
Fatty liver study in inflammatory bowel disease patients
This study checks how often people with Crohn's or ulcerative colitis also have fatty liver disease. It uses a painless scan to measure liver stiffness and fat. If you have IBD, you may join to help researchers learn about the link between these conditions.
