Observing Neurofilament Light Chain Levels and Patient Satisfaction with Subcutaneous Ocrelizumab Treatment in Adults with Multiple Sclerosis

What this Trial Is About

This research aims to evaluate participant satisfaction with subcutaneous ocrelizumab treatment in people with Multiple Sclerosis MS over a 12-month period. It will also investigate changes in neurofilament light chain NfL protein levels, a marker related to MS disease activity, and explore correlations between NfL levels and various clinical and imaging factors. The study is observational and follows participants who are starting ocrelizumab SC as part of their routine MS care. Participants will receive ocrelizumab as a subcutaneous injection according to their physicians discretion and local clinical practice. The study observes participants for up to 12 months to assess treatment satisfaction using the Therapy Administration Satisfaction Questionnaire for Subcutaneous administration TASQ-SC and other satisfaction questionnaires. Blood samples will be collected at baseline, month 6, and month 12 to measure NfL protein levels and other biomarkers. The study also monitors MS relapses, disability scores, and adverse events during this period. Throughout the 12 months, participants will undergo assessments of treatment satisfaction at multiple time points, including after the first injection, 6 months, and 12 months. Clinical evaluations, questionnaires, and blood tests will be conducted to track disease activity and participant experience. Researchers will measure satisfaction levels, changes in NfL concentrations, relapse rates, disability progression, and safety events. The study is designed to provide real-world data on patient experience and biomarker changes with subcutaneous ocrelizumab treatment in MS.
