Clinical Details

Official title: A Phase III, Randomized, Multi-Centre, Double-Blind, Double Dummy, Parallel Group, Placebo-Controlled Study to Evaluate the Efficacy and Safety of Two Doses of SPD476 (Mesalazine) 2.4g and 4.8g Once Daily, With Reference to ASACOL 0.8g Three Times Daily, in Subjects With Mild to Moderate Ulcerative Colitis

Study design: Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Placebo Control, Parallel Assignment, Safety/Efficacy Study

Primary outcome: Percentage of subjects in remission (UC-DAI score <=1, with scores of 0 for rectal bleeding and stool frequency and a sigmoidoscopy score reduction of 1 point or more from baseline)

Secondary outcome:

Clinical improvement as defined by a drop of => 3 points from baseline in the overall UC-DAI score

Change from baseine in UC-DAI score, symptoms, sigmoidscopy score, and PGA

Clinical remission defined as subjects who scored 0 for both the total stool frequency and the total rectal bleeding score

Treatment failure defined as unchanged, worsened missing or imcomplete UC-DAI score
