A Phase II, Randomized, Open-label, Parallel Group, Multicenter Study to Assess Bioequivalence of Two Subcutaneous Formulations of Ocrelizumab in Patients With Multiple Sclerosis

The main purpose of this study is to assess the bioequivalence of ocrelizumab SC test formulation to the marketed ocrelizumab SC reference formulation in participants with either relapsing multiple sclerosis (RMS) or primary progressive multiple sclerosis (PPMS). The study consists of 2 phases: a controlled phase, where participants in each group will receive one dose of test or reference formulation and a continuation phase, where all participants in both groups will receive ocrelizumab SC test formulation.
