A Study of Ocrelizumab in Participants With Relapsing Remitting Multiple Sclerosis (RRMS) Who Have Had a Suboptimal Response to an Adequate Course of Disease-Modifying Treatment (DMT)

Participants who complete their Week 72 ocrelizumab infusion and do not experience any serious infusion related reaction (IRR) throughout the main study will be eligible to enroll in an optional, open-label, non-randomized substudy to MN30035 and receive one additional shorter infusion of ocrelizumab at the Week 96 visit. This substudy will enroll approximately 100 patients from MN30035 main study.
