This research aims to assess the physical impact of Multiple Sclerosis MS from the participants perspective. It also provides participants continued access to the medication ocrelizumab while evaluating its safety and tolerability. The study is an open-label extension phase 3 trial sponsored by Hoffmann-La Roche, focusing on patients previously enrolled in related studies who currently lack local access to ocrelizumab treatment. Participants will receive ocrelizumab either as a 600 mg intravenous infusion or a 920 mg subcutaneous injection, following the dosing schedule established in their prior parent study. Treatment will continue until local access to the drug becomes available, if safety concerns arise, if the participant withdraws consent, or in the event of death. During the study, participants will be monitored for changes in physical functioning using patient-reported outcome measures over up to five years. Researchers will also track the number of participants receiving ocrelizumab and monitor adverse events, including serious or special interest events that may lead to discontinuation. Safety and tolerability assessments will continue throughout the study duration, which may last up to five years.
