Arm | Intervention/treatment |
---|---|
Experimental: Cohort 1
Participants with a body weight from >/= 25 kg to < 40 kg (with at least 2 participants with a body weight from >/= 25 kg to </= 35 kg) will receive 300 milligram (mg) ocrelizumab
|
Drug: Ocrelizumab
Ocrelizumab is administered as two infusions of half the dose given 14 days apart for the first dose, then subsequent doses are administered as a single infusion every 24 weeks. Cohort 1: total dose of 300 mg Cohort 2: total dose of 600 mg Cohort 3 and 4: additional dose level(s) may be lower than 300 mg, between 300 mg and 600 mg, or higher than 600 mg, but will be no higher than 1200 mg |
Experimental: Cohort 2
Participants with a body weight >/= 40 kg (with at least 2 participants with a body weight >/= 40 kg but </= 50 kg) will receive 600 mg ocrelizumab
|
Drug: Ocrelizumab
Ocrelizumab is administered as two infusions of half the dose given 14 days apart for the first dose, then subsequent doses are administered as a single infusion every 24 weeks. Cohort 1: total dose of 300 mg Cohort 2: total dose of 600 mg Cohort 3 and 4: additional dose level(s) may be lower than 300 mg, between 300 mg and 600 mg, or higher than 600 mg, but will be no higher than 1200 mg |
Experimental: Cohort 3 (optional)
Based on PK, PD, safety, and tolerability data analyses of Cohorts 1 and 2, additional participants with a body weight from >/= 25 kg to < 40 kg may be enrolled and receive another dose level of ocrelizumab
