The purpose of this study is to determine the long-term safety of RPC1063 for the treatment of all patients with moderate to severe Ulcerative Colitis (UC) as well as the long-term efficacy of RPC1063 for the treatment of adult patients with moderate to severe UC. Additionally, to determine the long-term efficacy of RPC1063 for the treatment of adolescent patients with moderate to severe UC.

Official Title

A Phase 3, Multicenter, Open-Label Extension Trial of Oral RPC1063 as Therapy for Moderate to Severe Ulcerative Colitis


The trial is an open label extension study. Eligible patients from the RPC01-3101 and RPC01-202 trials will have the option to enroll in this trial to receive study medication until the end of 2021 or until marketing approval of RPC1063 for UC is obtained in their country, or until the Sponsor discontinues the development program, whichever comes first.
