A trial looking at aspirin, metformin and resveratrol to prevent bowel polyps (COLO-PREVENT)

This trial is looking at aspirin by itself and in combination with metformin to prevent bowel polyps. The researchers are also looking at a food supplement called resveratrol to see if this can prevent bowel polyps.

It is open to people who have had a colonoscopy to remove polyps from their bowel as part of the NHS Bowel Cancer Screening Programme (BCSP).
