Experimental: Ocrelizumab Higher Dose
Participants will be randomized to receive a minimum of 5 higher treatment doses (1200 mg or 1800 mg) of ocrelizumab administered by intravenous (IV) infusion every 24 weeks in the double blind treatment (DBT) phase. During the optional open-label extension (OLE) phase, participants will continue with their assigned dose of ocrelizumab (either 1200 or 1800 mg) for approximately 96 weeks (4 doses in total). Mandatory methylprednisolone (or equivalent) and antihistaminic drug (e.g., diphenhydramine or equivalent) will be administered approximately 30-60 minutes prior to the start of each ocrelizumab infusion.
|
Drug: Ocrelizumab
The actual higher dose of ocrelizumab will be assigned to participants based on their body weight at baseline: 1200 mg (participants's body weight <75 kg) or 1800 mg (participant's body weight >/=75 kg). The first dose of ocrelizumab will be administered as two 600 mg or 900 mg intravenous (IV) infusions given 14 days apart. For the subsequent doses, ocrelizumab will be administered as a single 1200 mg or 1800 mg IV infusion every 24 weeks.
Other Name: Ocrevus Drug: Antihistamine 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.
Other Name: Non-Investigational Medicinal Product Drug: Methylprednisolone Premedication with 100 mg of methylprednisolone (or equivalent) will be administered by IV infusion prior to each ocrelizumab infusion.
Other Name: Non-Investigation Medicinal Product |
Active Comparator: Ocrelizumab Approved Dose
Participants will be randomized to receive a minimum of 5 treatment doses of 600 mg ocrelizumab administered by intravenous (IV) infusion every 24 weeks in the DBT phase. During the optional OLE phase, participants will be offered a higher dose of ocrelizumab (either 1200 or 1800 mg), based on their body weight at OLE baseline, for approximately 96 weeks (4 doses in total). Mandatory methylprednisolone (or equivalent) and antihistaminic drug (e.g., diphenhydramine or equivalent) will be administered approximately 30-60 minutes prior to the start of each ocrelizumab infusion.

Drug: Ocrelizumab
Ocrelizumab will be administered at a dose of 600 milligram (mg) every 24 weeks. The first dose of ocrelizumab will be administered as two 300 mg intravenous (IV) infusions given 14 days apart. For the subsequent doses, ocrelizumab will be administered as a single 600 mg IV infusion every 24 weeks.
Other Name: Ocrevus Drug: Antihistamine 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.

- Change from baseline in the Multiple Sclerosis Impact Scale-29 (MSIS-29) physical scale at Week 120 [ Time Frame: Baseline, Week 120 ]The MSIS-29 is a 29-item participant-reported measure of the physical and psychological impacts of MS. Participants are asked to rate how much their functioning and well-being has been impacted over the past 14 days on a 4-point scale, from "Not at all" (1) to "Extremely" (4).
- Annual rate of percent change from baseline in total brain volume [ Time Frame: Baseline up to approximately 4.3 years ]
- Time to 12-week Confirmed 4-point Worsening in Symbol Digit Modality Test (SDMT) [ Time Frame: Baseline up to approximately 4.3 years ]The SDMT is a performance measure that has demonstrated sensitivity in detecting not only the presence of cognitive impairment but also changes in cognitive functioning over time and in response to treatment. Using a reference key, the examinee has 90 seconds to pair specific numbers with given geometric figures. Responses will be collected orally. A four-point change from baseline is typically considered clinically meaningful.
