This clinical trial is focused on studying Lynch syndrome, a genetic condition that increases the risk of developing colorectal cancer. The trial aims to test whether a medication called mesalamine (also known as 5-ASA) can help prevent the development of any colorectal tumors, both non-cancerous and cancerous, in patients with Lynch syndrome. Mesalamine is being compared to a placebo, which is a substance designed to look like the actual medication but does not contain any active ingredients.
Participants in the study will receive either mesalamine or the placebo over a period of 24 months, with an additional follow-up period of 3 months. During this time, regular colonoscopies, which are procedures that allow doctors to look inside the colon, will be conducted to monitor for any signs of tumor development. The goal is to see if mesalamine can reduce the occurrence of colorectal tumors compared to the placebo.
The study will also gather information on the number of tumors per patient, how the tumors progress, and whether the effects of the treatment vary based on factors like a patient’s history of colorectal cancer, gender, and age. Safety data will also be collected and compared between the groups receiving mesalamine and the placebo. This research is important for understanding how to better prevent colorectal cancer in individuals with Lynch syndrome.
