This randomized, double-blind, double-dummy, parallel-group study will evaluate the efficacy and safety of ocrelizumab in comparison with Rebif (interferon beta-1a) in participants with relapsing multiple sclerosis. Participants will be randomized to receive either in Group A, ocrelizumab 600 milligram (mg) intravenously (IV) every 24 weeks plus Rabif placebo subcutaneously (SC) 3 times weekly, or, in Group B, Rebif 8.8 microgram (mcg) (Weeks 1 and 2), 22 mcg (Weeks 3 and 4), and 44 mcg (Week 5 and thereafter) SC 3 times weekly plus ocrelizumab placebo IV 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, providing they fulfill the eligibility criteria.
