Could a common probiotic keep precancerous colon polyps away?
NCT ID NCT07167342
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether taking a probiotic called Clostridium butyricum can prevent colorectal adenomas (precancerous polyps) from returning after they are removed during a colonoscopy. About 294 adults aged 18-75 who have had all visible polyps removed will take either the probiotic or a placebo daily for up to 3 years. They will have yearly colonoscopies to check for new polyps.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Clostridium butyricum (a probiotic bacteria)
What this could lead to
If it works, this could offer a simple, safe way to prevent precancerous colon polyps from returning after removal.
What could go wrong
This is a Phase 4 trial, but probiotics are not proven to prevent polyps. The effect may be small or none, and results may not apply to everyone.
