GLP-1 drug and diet study for Crohn's disease patients
This study tests a drug that helps with weight loss and blood sugar (called a GLP-1 receptor agonist) combined with a special diet to see if it can improve symptoms in people with mild Crohn's disease. You may join if you have Crohn's, a BMI of 27 or higher, and are already on a stable dose of a TNF blocker.

Common questions
- Are there clinical trials studying S-1?
- Yes. Clin2 currently lists 799 recruiting studies that include S-1, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a S-1 trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is S-1 an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether S-1 or a specific trial is right for you.
