Summary
This is a multicenter, randomized, double-blind, placebo-controlled study evaluating rosiglitazone: 4 mg tablets or placebo tablets administered orally twice daily for 12 weeks. The purpose of the study is to evaluate the efficacy and safety of rosiglitazone in the treatment of mild to moderately active ulcerative colitis. Disease activity will be measured using a standard disease activity index. Calculation of the index requires patients to undergo flexible sigmoidoscopy at the start of the study and at week 12.
