The primary objective of this expanded access program is to provide ocrelizumab as treatment for eligible participants with primary progressive multiple sclerosis (PPMS) before it is commercially available in the United States (U.S.) for the indication of PPMS.
Participants will receive 600 mg ocrelizumab as two 300 mg infusions separated by 14 days, every 24 weeks.
