A Randomized, Double-Blind, Double-Dummy, Parallel-Group Study To Evaluate the Efficacy and Safety of Ocrelizumab in Comparison to Interferon Beta-1a (Rebif®) in Patients With Relapsing Multiple Sclerosis

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 patients with relapsing multiple sclerosis. Patients will be randomized to receive either in group A, ocrelizumab 600 mg intravenously (iv) every 24 weeks plus Rebif placebo subcutaneously (sc) three times weekly, or, in group B, Rebif 8.8 mcg (Weeks 1+2)/22 mcg (Weeks 3+4)/44 mcg (Week 5 and following) sc three times weekly plus ocrelizumab placebo iv every 24 weeks. Anticipated time on study treatment is 96 weeks.
