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.
