Primary Outcome Measures:
  • The primary efficacy endpoint is the proportion of active subjects at Week 8 to achieve improvement from baseline and the proportion of maintenance subjects who experience relapse before Week 24. [ Time Frame: 8 weeks for Active Phase & 24 weeks for maintenance phase ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Secondary Endpoints Safety will be compared between the two 5-ASA groups in both the active and the maintenance phase of the study. [ Time Frame: 8 weeks for active & 24 weeks for maintenance phase. ] [ Designated as safety issue: Yes ]
