Brief summary
RATIONALE: Exisulind may be effective in preventing the development and growth of polyps in patients who have familial adenomatous polyposis. PURPOSE: Randomized phase II/III trial to determine the effectiveness of exisulind in preventing the development and growth of polyps in patients who have familial adenomatous polyposis.
Detailed description
OBJECTIVES: * Determine the ability of exisulind to inhibit growth and development of duodenal adenomas in patients with familial adenomatous polyposis. * Determine the effect on apoptosis in polyp vs mucosal tissue in these patients when treated with this drug. OUTLINE: This is a randomized, double-blind, placebo-controlled study. Patients are randomized to one of two treatment arms. * Arm I: Patients receive oral exisulind 4 times daily. * Arm II: Patients receive oral placebo 4 times daily. Treatment continues for 1 year.
