This 2-year study will evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamic (PD) effects of ocrelizumab in children and adolescents ages >/= 10 to < 18 years with relapsing-remitting multiple sclerosis (RRMS). The first 24-week period will serve to determine the dose of ocrelizumab to be further investigated in the subsequent Phase III study in children and adolescents.
