ClinConnect Summary

This clinical trial is studying whether Shenbai Granules, a traditional Chinese medicine formula, can help prevent the return of low-risk colorectal adenomas. Colorectal adenomas are small growths in the colon that can sometimes lead to cancer if they come back after removal. The study will include about 450 adults aged 40 to 75 who have recently had these growths completely removed and who meet specific traditional Chinese medicine criteria related to a condition called "spleen deficiency with dampness-heat." Participants will be randomly assigned to receive either Shenbai Granules or a placebo (a harmless inactive substance) without knowing which one they get.

If you join the study, you can expect regular check-ups to see if the adenomas come back and to monitor your health and any side effects. The goal is to find out if Shenbai Granules are safe and effective in reducing the chance of adenomas returning over two years. People with certain health problems, recent use of specific medications, or who are pregnant will not be eligible. This study is not yet recruiting, but if you fit the criteria, it may offer a new way to help lower the risk of colorectal growths coming back after removal.
