Title: 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
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.


Options:
A: Inclusion Criteria:

* In fertile females, willing to comply with effective contraceptive methods. These include birth control pills, surgical sterilization of patient or partner or intrauterine device. Non-fertile women is defined as more than 12 months of amenorrhea without an alternative medical cause or, in case of ambiguities, an follicle stimulation hormone level in the postmenopausal range.

Exclusion Criteria:

Hepatitis serology (HBsAg and anti-HBc) will be evaluated before treatment onset.
