A Study of Ocrelizumab in Children and Adolescents With Relapsing-Remitting Multiple Sclerosis

Running, not enrolling · Phase 2

Conditions studied: Multiple Sclerosis

In brief

This 2-year study will evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamic (PD) effects of ocrelizumab in children and adolescents ages ≥ 10 to ≤ 18 years with relapsing-remitting multiple sclerosis (RRMS). The data from this study will serve to determine the dosing regimen of ocrelizumab to be further investigated in the subsequent Phase III study in children and adolescents.
