Could a common antibiotic ease Kids' bowel disease?
NCT ID NCT07646223
First seen Jun 26, 2026 · Last updated Sep 11, 2026 · Updated 3 times
Summary
This study tests whether oral vancomycin, an antibiotic, can help children aged 6-15 with inflammatory bowel disease (IBD), especially types linked to liver problems. About 140 kids will either get vancomycin plus standard care or standard care alone for up to a year. Researchers will check if it improves symptoms, gut bacteria, and overall health.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- oral vancomycin
- What this could lead to
- If it works, this could point toward a new treatment option for children with certain types of inflammatory bowel disease, especially those with liver involvement.
- What could go wrong
- This is an early Phase 2 trial with only 140 children, so results may not apply to everyone. The treatment requires long-term use and may cause side effects or not work for all types of colitis.
