Title: A Phase 2/3, Multi-center, Randomized, Double-blind, Placebo-controlled (Part A) and Double-blind, Double-dummy, Active-controlled (Part B), Parallel Group Study to Evaluate the Efficacy and Safety of RPC1063 Administered Orally to Relapsing Multiple Sclerosis Patients
Brief Summary: This study is a two-part trial consisting of Part A (see NCT01628393) and Part B, presented within this record.

The primary objective of Part B is to assess whether the clinical efficacy of ozanimod (RPC1063) is superior to interferon beta-1a (IFN β-1a; Avonex®) in reducing the rate of clinical relapses at the end of Month 24 in patients with relapsing multiple sclerosis (RMS).
