Drug: SPD476 is a polymeric matrix formulation that displays both delayed- and extended-release of mesalazine
Drug: Mesalazine
Phase 3

Study Type: Interventional

Further study details as provided by Shire:

Primary Outcome Measures:
  • 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) [ Time Frame: 8 weeks ]

Secondary Outcome Measures:
  • Clinical improvement as defined by a drop of => 3 points from baseline in the overall UC-DAI score [ Time Frame: 8 weeks ]
  • Change from baseine in UC-DAI score, symptoms, sigmoidscopy score, and PGA [ Time Frame: 8 weeks ]
  • Clinical remission defined as subjects who scored 0 for both the total stool frequency and the total rectal bleeding score [ Time Frame: 8 weeks ]
  • Treatment failure defined as unchanged, worsened missing or imcomplete UC-DAI score [ Time Frame: 8 weeks ]
