Could a Crohn's drug tame a rare stomach disease?
NCT ID NCT06317220
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Phase 2 trial tests whether vedolizumab (Entyvio), a drug used for inflammatory bowel disease, can reduce symptoms of collagenous gastritis—a rare condition causing stomach pain, nausea, and bloating. Eleven participants receive the drug via IV and report their symptoms over 12 weeks. The study also checks safety and how long any benefits last.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- vedolizumab (Entyvio)
- What this could lead to
- If it works, this could point toward a treatment for collagenous gastritis, a rare stomach condition with limited options.
- What could go wrong
- This is a very small, early-phase trial with only 11 participants, so results may not apply to everyone. Vedolizumab also carries risks like allergic reactions or infections.
