Primary

MeasureTime frame
Main Objective: To assess the efficacy of a new oral formulation of 2-PPA (PEAC minitablet), given as a 6-months treatment of colorectal polyps in patients with familial adenomatous polyposis (FAP) in comparison to a placebo treatment.;Secondary Objective: To assess the safety of a new oral formulation of 2-PPA (PEAC minitablet), given as a 6-months treatment of colorectal polyps in patients with familial adenomatous polyposis (FAP) in comparison to a placebo treatment.;Primary end point(s): The primary endpoint for assessment of efficacy will be • the percentage change in the total number of polyps with a diameter > 2 mm at the end of the 6-months treatment period compared to baseline as determined from video tapes of colonoscopy before and after treatment by three independent physicians qualified in colonoscopy.
