Question: What are clinical trials for Crohn’s disease?
Answer: Clinical trials—and other types of clinical studies—are part of medical research and involve people like you. When you volunteer to take part in a clinical study, you help doctors and researchers learn more about disease and improve health care for people in the future.

Researchers are studying many aspects of Crohn’s disease and other types of inflammatory bowel disease (IBD), such as

diet and themicrobiome’seffect on Crohn’s disease

Question: What clinical studies for Crohn’s disease are looking for participants?
Answer: You can view a filtered list of clinical studies on Crohn’s disease that are federally funded, open, and recruiting at ClinicalTrials.gov. You can expand or narrow the list to include clinical studies from industry, universities, and individuals; however, the National Institutes of Health does not review these studies and cannot ensure they are safe for you. Always talk with your health care provider before you participate in a clinical study.
Question: What have we learned about Crohn’s disease from NIDDK-funded research?
Answer: NIDDK has supported many research projects to learn more about Crohn’s disease and other types of IBD. NIDDK-supported research efforts include

theIBD Genetics Consortium (IBDGC), established in 2002 to identify genes that make some people more likely to develop IBD. The IBDGC, in collaboration with theInternational IBD Genetics Consortium, has enrolled thousands of people with IBD and identified about 200 regions of the human genome that are associated with the risk of IBD.
studies through theNIH Integrative Human Microbiome Project, which have examined the relationship between the microbiome and IBD.
