Summary

1. Complete a large-sample, multicenter, randomized blank-controlled clinical trial to evaluate Shenling Baizhu Granules for the prevention of colorectal adenoma recurrence. 2. Generate high-level, internationally recognized clinical evidence to support the development of clinical practice guidelines for the prevention and treatment of colorectal adenoma using traditional Chinese medicine, and to strengthen the recommendation level of Shenling Baizhu Granules in clinical guidelines. 3. Define the clinical characteristics of patient subgroups most likely to benefit from Shenling Baizhu Granules for preventing colorectal adenoma recurrence.

Detailed description

This study is designed within the traditional Chinese medicine (TCM) framework for colorectal adenoma and will be conducted as a prospective, multicenter, open-label, randomized, blank-controlled clinical trial. All participants will undergo standard endoscopic minimally invasive treatment and receive health education. In addition to these measures, participants in the intervention group will receive Shenling Baizhu Granules (6 g per dose, three times daily). The intervention will be initiated within 3 months after the baseline treatment/health education and continued for 6 consecutive months. Participants in the control group will not receive Shenling Baizhu Granules. At baseline, demographic characteristics, adenoma-related information, and TCM syndrome assessment scores will be collected. Follow-up will be conducted every 6 months during the first 2 years, and once in the third year. Biospecimens and TCM assessments will be collected at three time points: (i) baseline, (ii) 6 months after initiation of medication in Year 1, and (iii) after colonoscopic reassessment in Year 3. At each time point, plasma, stool, tongue coating, saliva, and tissue samples, as well as the TCM syndrome assessment questionnaire, will be obtained. To characterize the subpopulation most likely to benefit from Shenling Baizhu Granules in preventing colorectal adenoma recurrence, we will integrate and analyze: baseline clinical factors (e.g., age, sex, family history of cancer, smoking and alcohol use); conventional medical features (e.g., adenoma location, number, size, histopathological type, and concomitant medications); TCM-related features (e.g., evolution of TCM syndrome patterns and objective tongue/pulse parameters); and biological profiles (e.g., cytokines, proteins, metabolites, and gut microbiota). Common characteristics of the beneficial population will then be summarized based on these multidimensional data.

Conditions

• Low-risk Colorectal Adenoma

Interventions

Type	Name	Description
DRUG	Shenling Baizhu granules (TCM patent medicine)	Shenling Baizhu granules is a traditional Chinese medicine preparation in granular form. Participants in the experimental group will take 6 g orally three times daily for 6 months, initiated within 3 months after baseline endoscopic resection and health education. The granules should be taken before meals or at the same time as eating. The granules contain multiple Chinese herbs including Ginseng, Poria, Atractylodes macrocephala, and other traditional ingredients. This formulation is standardized according to Chinese pharmacopoeia standards and is manufactured under GMP conditions. This intervention is being tested for its ability to prevent the recurrence of low-risk colorectal adenomas after endoscopic resection.
