- Participants naive to prior disease-modifying therapy (DMT)
- Participants who have had at least 6 contiguous months of DMT within the past 1 year must have evidence of disease activity occurring after the full 6-month course of treatment, that is, at least one relapse or >/= 1 Gd-enhancing lesion(s) on a T1-weighted brain MRI
Exclusion Criteria:
- Known presence or suspicion of other neurologic disorders that may mimic MS, including, but not limited to, acute disseminated encephalomyelitis, neuromyelitis optica or neuromyelitis optica spectrum disorders and any neurologic, somatic, or metabolic condition that could interfere with brain function or normal cognitive or neurological development

- History or known presence of recurrent or chronic infection (e.g., HIV, syphilis, tuberculosis)
- Receipt of a live or live-attenuated vaccine within 6 weeks prior to treatment allocation
- History or laboratory evidence of coagulation disorders

- Inability to complete a magnetic resonance imaging (MRI) scan
- History of cancer, including solid tumors, hematologic malignancies, and carcinoma in situ
- History of a severe allergic or anaphylactic reaction to humanized or murine monoclonal antibody (mAbs) or known hypersensitivity to any component of ocrelizumab solution
- Previous treatment with B-cell-targeted therapies
- Percentage of CD4 < 30%
- Absolute Neutrophil Count < 1.5x1000/microliter
- Lymphocyte count below the lower limit of normal (LLN) for age- and sex-specific reference range

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
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
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
