Brief Summary:
The purpose of this study is to determine whether RPC1063 is effective in the treatment of Ulcerative Colitis (UC).

Condition or disease Intervention/treatment Phase
Ulcerative Colitis Drug: RPC1063 Drug: Placebo Phase 3

Detailed Description:
The trial is composed of 2 periods: Induction and Maintenance. In the Induction Period (IP), patients will be entered into the trial in 3 separate cohorts (Cohort 1 and Cohort 2 for adults, Cohort 3 for adolescents). Patients from Cohort 1, 2, and 3 in clinical response at the end of the IP will proceed through to the Maintenance Period (MP). Patients from Cohort 1, 2, and 3 who participate in this trial may also qualify to participate in an optional Open-Label Extension (OLE) trial.
