This study tests a new surgery for people with Crohn's disease in the last part of the small intestine. The surgery removes the diseased section and nearby fatty tissue, then reconnects the bowel in a special way (Kono-S anastomosis). The goal is to see if this lowers the chance …

This early-stage study tests a new imaging agent called 18F-4FN for PET scans to safely detect inflammation in the body. It involves 55 adults with cancer who are on immunotherapy or have suspected inflammation. The goal is to see if this agent can highlight areas of inflammation…

This study compares a new imaging technique called Texture and Colour Enhancement Imaging (TXI) with standard white light during colonoscopy in 219 people with inflammatory bowel disease (IBD). The goal is to see if TXI finds more dysplastic (precancerous) lesions. Each patient w…

This study is testing a device called the AlgometRx Nociometer to see if it can measure inflammation in children with inflammatory bowel disease (IBD). The device checks how different nerve fibers respond, which may give doctors a clearer picture of disease activity. Researchers …

This study is testing a web-based tool that estimates a person's risk of developing Crohn's disease based on their lifestyle and family history. Researchers will enroll 80 healthy people who have a parent or sibling with inflammatory bowel disease. Participants will receive perso…

This study aims to learn more about how diseases related to blood clots, the immune system, and blood vessels start and change over time. Researchers will enroll up to 1,000 people aged 5 and older, including those with these conditions, their healthy relatives, and healthy volun…

This study is checking how common chronic kidney disease is in children with inflammatory bowel disease (IBD), like Crohn's disease or ulcerative colitis. Researchers will look at medical records from 600 children with IBD and compare them to children without IBD. The goal is to …

This study compares using one doctor versus two doctors to perform a procedure called single-balloon enteroscopy, which looks deep into the small intestine. About 228 adults with suspected small bowel disease will be randomly assigned to either technique. The goal is to see if on…

This study looks for better ways to detect lung inflammation and infections early in people who have received a stem cell transplant from a donor. About 40 participants aged 5 to 70 will get regular lung scans, breathing tests, blood draws, and a procedure where a tube collects f…

This study aims to learn how the immune system controls inflammation in the gut for people with Crohn's disease or ulcerative colitis. Up to 1,000 participants aged 0 to 75 will receive standard medical care and may provide blood, tissue, or white blood cell samples. No experimen…

This study aims to collect medical data and biological samples (blood, urine, stool, and tissue) from up to 4,000 adults with known or suspected gastrointestinal diseases. Participants receive standard medical care at the NIH, and any extra samples or leftover tissue from procedu…

This study follows 450 adults who have early signs of inflammatory bowel disease (Crohn's or ulcerative colitis) found during routine colon cancer screening, but who have no symptoms yet. Researchers will collect blood, stool, and tissue samples over time to see how the disease p…

This study is testing a tool called B-COMPASS that uses a 22-question survey to predict whether people will follow their prescribed treatments. Researchers will enroll 3100 adults with cardiovascular, endocrine, immune, nerve, cancer, or rare diseases across Europe. The goal is t…

This pilot study is measuring prednisolone levels in 120 people with inflammatory diseases like thyroid eye disease, vasculitis, COPD, asthma, and others. Participants take high-dose prednisolone as part of their routine care, and researchers take timed blood samples to see how t…

This early-phase study at Stanford University is testing whether the statin drug rosuvastatin changes bile acid levels and gut bacteria in people with primary sclerosing cholangitis (PSC), a liver disease with no cure. Researchers will enroll 15 adults with PSC and inflammatory b…

This study looks at 320 adults who are about to start strong immune-suppressing therapy and have already had at least two COVID-19 shots. Researchers want to find out if giving a COVID-19 booster right before starting therapy or waiting six months provides better protection. Part…

This study is creating a large registry of 800 people receiving biologic medications for immune conditions like autoimmune diseases and primary immune deficiencies. Researchers will collect blood samples and health data to better understand how these treatments work and who respo…
