Study Overview
Brief Summary
The purpose of this study is to determine whether RPC1063 is effective in the treatment of Ulcerative Colitis (UC).
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 2 separate cohorts (Cohort 1 and Cohort 2).Patients from Cohort 1 and 2 in clinical response at the end of the IP will proceed through to the Maintenance Period (MP). Patients from Cohort 1 and 2 who participate in this trial may also qualify to participate in an optional Open-Label Extension (OLE) trial.
