Interventions

Ocrelizumabdrug

The actual higher dose of ocrelizumab will be assigned to participants based on their body weight at baseline: 1200 mg (body weight \<75 kg) or 1800 mg (body weight ≥ 75 kg). The first dose of ocrelizumab will be administered as two 600 mg or 900 mg IV infusions given 14 days apart. For the subsequent doses, ocrelizumab will be administered as a single 1200 mg or 1800 mg IV infusion Q24W. During the optional OLE phase, participants will continue with their assigned dose of ocrelizumab (either 1200 or 1800 mg) for approximately 96 weeks (4 doses in total).

Ocrelizumabdrug

Ocrelizumab will be administered at a dose of 600 mg Q24W. The first dose of ocrelizumab will be administered as two 300 mg IV infusions given 14 days apart. For the subsequent doses, ocrelizumab will be administered as a single 600 mg IV infusion Q24W.

Antihistaminedrug

Premedication with oral or IV antihistaminic drug (i.e., diphenhydramine 50 mg or an equivalent dose of an alternative) will be administered prior to each ocrelizumab infusion.
