About

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).

Enrollment: 835 patients

Sex: All

Ages: 18 to 55 years old

Volunteers: No Healthy Volunteers

• Neurologic stability for greater than or equal to (>/=) 30 days prior to both screening and baseline
• Expanded Disability Status Scale (EDSS) score 0 to 5.5 inclusive

Exclusion criteria

• Primary progressive multiple sclerosis
• Disease duration of more than 10 years in patients with EDSS score less than or equal to (</=) 2.0 at screening

• Active infection, or history of or known presence of recurrent or chronic infection (for example, hepatitis B or C, Human Immunodeficiency Virus [HIV], syphilis, tuberculosis)
• History of progressive multifocal leukoencephalopathy
• Contraindications to or intolerance of oral or IV corticosteroids
• Contraindications to Rebif or incompatibility with Rebif use
