Is this trial a fit for you?
✓Likely a good fit
Adults with relapsing-remitting MS who are starting SC ocrelizumab, switching from IV to SC, or switching from a prior DMT to SC, and who can complete the TASQ.
✕Probably not a fit
Patients who do not respond to SC ocrelizumab or who cannot complete the TASQ may not derive measurable satisfaction insights from the study.

What this trial studies
This observational study collects patient-reported satisfaction with subcutaneous ocrelizumab in adults with relapsing-remitting MS who are starting SC treatment, switching from IV to SC, or moving from another DMT to SC. It uses routine clinical practice decisions rather than experimental interventions. Participants complete a patient-reported outcome questionnaire (TASQ) to gauge satisfaction. The study does not randomize treatments or compare against a control group. Data will reflect real-world experiences in eligible European clinical settings.
Why it matters
Potential benefit: If successful, the study could show that SC ocrelizumab is acceptable and satisfactory for patients, potentially supporting broader adoption.
How similar studies have gone: Other observational work has explored patient satisfaction with SC biologics in MS, suggesting potential favorable experiences with SC administration.

Show full inclusion / exclusion criteria
Inclusion Criteria: * Diagnosis of RRMS according to the revised McDonald criteria (2017 or 2024 revisions). * Initiation of ocrelizumab s.c in accordance with routine clinical practice and local prescribing information. * The decision to initiate ocrelizumab s.c. has been made by the treating physician prior to and independently of study participation. * Willingness to complete the patient-reported outcome questionnaire TASQ, where applicable. Exclusion Criteria: * Participation in any clinical study involving disease modifying therapies for multiple sclerosis during the study period or at the time of enrollment. * Prior treatment with rituximab. * Contraindications to ocrelizumab as per the local prescribing information. * Severe psychiatric or cognitive impairment that, in the opinion of the treating physician, would preclude informed consent, reliable participation in the study, or completion of patient-reported outcomes. * Any condition which, in the opinion of the treating physician, would interfere with participation in the study or the interpretation of study results. * For participants participating in a Market Research and Patient Support Program (MAP), inclusion is permitted only when a cross-reference to the unique MAP patient identifier is available.
