Clinical Trial Summary

This is a prospective, multicenter, open-label, single-arm, phase 3b study which evaluates effectiveness and safety of ocrelizumab in participants with early stage RRMS. The study will consist of an open-label treatment period of 192 weeks and follow-up period of at least 48 weeks. The optional shorter infusion substudy will evaluate the safety of a shorter infusion of ocrelizumab in a subgroup of participants with early stage RRMS enrolled in the main MA30143 study. Approximately 700 patients will be enrolled in the substudy, and will receive additional 600 mg ocrelizumab administered in a shorter time frame.
