Design outcomes

Primary

Measure	Time frame
Main Objective: The primary objective of this study is to assess whether the efficacy of ocrelizumab 600 mg intravenously every 24 weeks is superior to Rebif® as measured by the annualized protocol-defined relapse rate by two years in patients with relapsing multiple sclerosis.;Secondary Objective: To evaluate whether the efficacy of ocrelizumab is superior to Rebif®, as reflected by the following measures: • The time to onset of confirmed disability progression for at least 12 weeks with the initial event of neurological worsening occurring during the 96-week, double-blind, double-dummy, treatment period. • The total number of new T1 Gd-enhancing lesions as detected by brain MRI at weeks 24, 48 and 96 • The total number of new, and/or enlarging T2 hyperintense lesions as detected by brain MRI at Weeks 24, 48, and 96. • The proportion of patients who have confirmed disability improvement for at least 12 weeks initial event of neurological improvement occurring during the 96-week, double-blind, double-dummy, treatment period. • The time to onset of confirmed disability progression for at least 24 weeks with the initial event of neurological worsening ocurring during the 96-week, double-blind, double-dummy, treatment period. See Section 2.2 of the protocol for full list;Primary end point(s): Annualized protocol-defined relapse rate at ;Timepoint(s) of evaluation of this end point: Week 96	—
