Proctitis

This study is testing a new surgical stapler, called the Signia circular stapler, in people having left-sided colon, sigmoid, or rectal surgery. The goal is to see if it lowers the chance of a leak where the colon is reconnected. About 137 adults will take part, and the main focu…

This phase 2 trial tests a drug called DISC-0974 in 21 adults with inflammatory bowel disease (IBD) who also have anemia caused by inflammation. The study aims to see if the drug safely raises hemoglobin levels compared to a placebo. Participants receive injections of either DISC…

This study tests whether combining guselkumab with JAK inhibitors (upadacitinib or tofacitinib) can help people with inflammatory bowel disease that hasn't improved with other treatments. About 80 participants will receive the drug combination and be monitored for 12 and 52 weeks…

This study tests whether improving nutrition before surgery reduces complications in people with inflammatory bowel disease (IBD). About 150 adults scheduled for intestinal surgery will receive a nutrition specialist and special shakes. Researchers will track hospital stay length…

This study is testing whether a smartphone app called SMART-IBD can help teenagers with inflammatory bowel disease (IBD) remember to take their medications and manage their symptoms. About 70 teens aged 13-17 will either use the full app with reminders and challenges or just a si…

This trial is developing an AI-powered device that listens to children's heart, breath, and bowel sounds to identify signs of common diseases like congenital heart disease, bronchopneumonia, and abdominal issues. It will involve 30,000 children aged 0-18, some with these conditio…

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 …

Researchers are testing whether tributyrin, a dietary supplement, can prevent radiation-induced rectal injury in people receiving chemoradiotherapy for locally advanced rectal cancer. About 23 participants will take tributyrin three times daily alongside standard treatment. The s…

This phase 2 trial tests whether a dietary supplement called tributyrin can reduce rectal bleeding in people who developed chronic radiation proctitis after pelvic radiotherapy. Participants take the supplement orally for 12 weeks, and researchers will measure changes in bleeding…

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 follows children aged 0 to 14 with suspected non-IgE food allergies, which cause digestive symptoms like reflux, colic, or constipation rather than immediate allergic reactions. Researchers will track symptoms, triggers, and growth over time, and analyze blood samples …

This study will follow 150 people with radiation rectal injury to see if different subtypes of the condition lead to different outcomes. Researchers will collect medical records, endoscopy images, and test results but will not change any treatments. The goal is to fill gaps in kn…

This study follows pregnant women with inflammatory bowel disease (IBD) and their children for up to four years after birth. Researchers want to see whether the mother's disease activity or use of immunosuppressant or biologic medications affects pregnancy outcomes or the child's…

This study follows 1,500 children newly diagnosed with inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, to understand why some respond well to treatments while others develop complications. Researchers will collect medical data and biological sa…

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 follows 1,000 adults who have long-term bladder or bowel problems from past cancer radiation and are receiving hyperbaric oxygen therapy (HBOT). Researchers want to learn which patients improve most and when treatment works best. The goal is to better understand how to…

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 looks at whether repeated sessions of hyperbaric oxygen therapy (HBOT) can damage DNA in people who have had radiation for cancer. HBOT is used to help heal tissues damaged by radiation, but it also creates reactive oxygen molecules that might harm DNA. Researchers wil…

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 40 newborns with isolated rectal bleeding to see how many have a cow's milk protein allergy versus a temporary condition called transient neonatal colitis. By removing and then reintroducing cow's milk from the diet, doctors can confirm an allergy if bleeding …

This trial is testing whether taking daily fiber supplements can change the types and amounts of bacteria living in the colon. The study involves 120 adults with benign anal or colorectal conditions who are not currently on fiber supplements. Researchers will compare gut bacteria…

The PLANET study is looking at whether tiny plastic particles in our environment can trigger gut inflammation and raise the risk of inflammatory bowel disease (IBD). Researchers will measure microplastics in stool samples from pregnant women, their healthy relatives, and people w…

This study is collecting health data, voice recordings, and biological samples from 100 IBD patients in Luxembourg (part of a larger 800-person study across Europe). Researchers hope to find patterns that can predict when a patient's treatment needs to change. The goal is to use …

This study is looking at why the immune system attacks the gut in people with celiac disease and other immune-related gut disorders. Researchers will collect blood and tissue samples from 200 adults to study immune cells and genes. The goal is to better understand what goes wrong…
