Jianpi Lishi Jiedu Granules for Prevention of Postoperative Recurrence in Colorectal Advanced Adenomas

Официальное название

A Multicenter, Randomized, Double-blind, Parallel-controlled Clinical Study on the Intervention of Jianpi Lishi Jiedu Granules for Postoperative Recurrence of Colorectal Advanced Adenomas

Обзор

This multicenter, randomized, double-blind, placebo-controlled trial aims to evaluate the efficacy and safety of Jianpi Lishi Jiedu Granules in preventing postoperative recurrence of colorectal advanced adenoma. A total of 376 patients aged 18-80 years with endoscopically resected advanced adenoma and diagnosed with Spleen Deficiency and Dampness Toxin syndrome will be enrolled and randomly assigned to receive either Jianpi Lishi Jiedu Granules or placebo for 3 months. The primary endpoint is the adenoma recurrence rate at 1 year post-treatment, assessed by colonoscopy and pathological examination. Secondary endpoints include malignant transformation rate, TCM syndrome improvement, quality of life, gastrointestinal symptoms, and exploratory analyses of gut microbiota and inflammatory cytokines.

Вмешательства

• Препарат Jianpi Lishi Jiedu Granules
  The intervention is orally administered as one sachet of Jianpi Lishi Jiedu Granules, twice daily (1 hour after breakfast and dinner), for a treatment course of 3 months. All participants will begin medication after resuming oral intake following surgery for colorectal advanced adenoma (≥2 weeks post-procedure).
• Препарат Placebo granules
  Participants in the control group will receive placebo granules orally (with the same specifications, appearance, dosage, and administration as the experimental group) for a treatment course of 3 months. All participants will begin medication after resuming oral feeding following surgery for colorectal advanced adenoma (≥2 weeks post-procedure).
