Primary Outcome(s)

Main Objective: The primary objective in this study is to investigate the effect of ocrelizumab given as two dose regimens of 600 or 1000 mg intravenously on the total number of gadolinium-enhancing T1 lesions observed on MRI scans of the brain at weeks 12, 16, 20 and 24 as compared with placebo.

- The total number of gadolinium-enhancing T1 lesions observed on MRI scans of the brain at Weeks 4, 8, 12, 16, 20 and 24;
- The total number of new and/or persisting gadolinium-enhancing T1 lesions on MRI scans of the brain at Weeks 4, 8, 12, 16, 20 and 24;
- Change in total volume of T2 lesions on MRI scans of the brain from baseline to Week 24;
- To evaluate the safety and tolerability of two dose regimens of ocrelizumab in patients with RRMS as compared with placebo and Avonex at Week 24 and the overall safety of ocrelizumab administered for up to 96 weeks;
- To investigate the pharmacokinetics and other pharmacodynamic study endpoints of ocrelizumab.

Secondary Outcome(s)

Timepoint(s) of evaluation of this end point: Weeks 4, 8, 12, 16, 20 and 24

Secondary end point(s): The secondary efficacy endpoints are:
• The annualized protocol defined relapse rate by Week 24
• Proportion of patients who remain relapse-free by Week 24 (protocol-defined relapses)
