Weight loss procedure for people with obesity and IBD

Mexico City, CuauhtemocAges 18–80 - NCT07533890Recruiting
Probiotics and gut health in children with inflammatory bowel disease
This study tests whether a multi-strain probiotic supplement can change the gut bacteria in children and teens with inflammatory bowel disease (IBD). Researchers will collect stool samples to see if the probiotics help restore healthy gut bacteria and potentially improve symptoms.
BernAges 5–18 - NCT07444060Recruiting
Guselkumab vs Ustekinumab for stricturing Crohn's disease
This study compares two medicines, Guselkumab and Ustekinumab, for people with Crohn's disease that causes narrowing (strictures) in the bowel. It aims to find which works better to improve symptoms and avoid the need for more procedures.

Common questions
- Are there clinical trials for bowel disease?
- Yes. Clin2 currently lists 275 recruiting bowel disease studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a bowel disease trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a bowel disease trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
