Spots Global Cancer Trial Database for Mesalamine for Colorectal Cancer Prevention Program in Lynch Syndrome

Study Description

Brief Summary: Multicenter, multinational, randomized, 3-arm, double-blind, phase II clinical study with 2400mg mesalamine, 1200mg mesalamine or placebo for prevention of colorectal neoplasia in Lynch Syndrome patients for 2 years.

Detailed Description: This is a multicenter, multinational, randomized, 3-arm, double-blind, phase II clinical study with 2400mg mesalamine (5-ASA), 1200mg mesalamine (5-ASA) or placebo in LS patients for a 2-year treatment. 540 tumor free carriers of a known genetic mutation in a major MMR gene (including patients in which the polyps are endoscopically removed) will be randomized 1:1:1 (180 each) to receive 2400mg mesalamine, 1200mg mesalamine or placebo. Patients will be identified through local or national registries and through collaboration with sites. Tumor free patients, assessed by white light high resolution colonoscopy, will be randomized to the study. A serum and stool sample will be taken to identify for mesalamine compliance and potential biomarkers. Biopsies of the normal tissue of ascending colon and rectum will be taken at the first and the last colonoscopy. The aim of the study is to investigate the effect of regular treatment with mesalamine (5-ASA) on the occurrence of any colorectal neoplasia, tumor multiplicity (the number of detected adenomas/carcinomas) and tumor progression in LS patients. A 50% reduction of the occurrence of colorectal neoplasia in mesalamine-treated patients is expected. Tumor multiplicity and tumor progression (severity of the neoplastic lesions) will be investigated.
