Study Overview
Brief Summary
This randomized, double-blind, double-dummy, parallel-group study will evaluate the efficacy and safety of ocrelizumab in comparison with interferon beta-1a (Rebif) in participants with relapsing multiple sclerosis. Participants will be randomized to receive either ocrelizumab 600 mg or matching placebo intravenous (IV) as 300 mg infusions on Days 1 and 15 for the first dose and as a single infusion of 600 mg for all subsequent infusions every 24 weeks, with placebo injections matching interferon beta-1a SC three times per week; or interferon beta-1a 44 mcg SC injections three times per week (with placebo infusions matching ocrelizumab infusions every 24 weeks). Planned duration of double-blind treatment is 96 weeks. Participants who complete the 96-week double-blind treatment will have an option to enter a single-group, active-treatment, open-label extension period, providing they fulfill the eligibility criteria.

Outcomes
Primary Outcomes
Annualized Relapse Rate (ARR) in Participants With Relapsing Multiple Sclerosis (MS) at 96 Weeks
Time Frame: Week 96
ARR was protocol-defined and calculated as the total number of relapses for all participants in the treatment group divided by the total participant-years of exposure to that treatment.
Secondary Outcomes
- Number of T1 Gadolinium (Gd)-Enhancing Lesions as Detected by Brain Magnetic Resonance Imaging (MRI) During the Double-Blind Treatment(Baseline up to Week 96)
- Number of New, and/or Enlarging T2 Hyperintense Lesions as Detected by Brain Magnetic Resonance Imaging (MRI) During the Double Blind Treatment(Baseline up to Week 96)
- Time to Onset of Confirmed Disability Progression (CDP) for at Least 12 Weeks During the Double-Blind Treatment Period(Week 108)
- Percentage of Participants With Confirmed Disability Improvement (CDI) for at Least 12 Weeks(Week 96)
- Number of T1 Hypointense Lesions During the Double-Blind Treatment(Baseline up to Week 96)
- Change From Baseline in Multiple Sclerosis Functional Composite (MSFC) Score to Week 96(Baseline, Week 96)
- Percent Change in Brain Volume as Detected by Brain Magnetic Resonance Imaging (MRI) From Week 24 to Week 96(From Week 24 up to Week 96)
- Time to Onset of Confirmed Disability Progression (CDP) for at Least 24 Weeks During the Double-Blind Treatment Period(Week 108)
- Change From Baseline in Short Form Health Survey-36 (SF-36) Physical Component Summary (PCS) Score at Week 96(Baseline, Week 96)
- Number of Participants With Adverse Events (AEs)(Baseline up to 588 weeks)
- Exposure to Ocrelizumab (Area Under the Concentration - Time Curve, AUC)(Pre-infusion at Weeks 1, 24, 48, 72; and 30 minutes post-infusion at Week 72; at any time during Weeks 84 and 96)
- Percentage of Participants Who Have No Evidence of Disease Activity (NEDA) up to Week 96(Week 96)
- Number of Participants With Anti-Drug Antibodies (ADAs) to Ocrelizumab(Baseline up to week 96)
