Assessment of the Quality of Life of Multiple Sclerosis Patients Treated With Ofatumumab in Real-life in France

This is a non-interventional, prospective (primary data), multicenter study conducted in metropolitan France. The primary objective of this study is to describe the quality of life of MS patients after initiation of treatment with ofatumumab. In order to form a representative sample of MS patients taking into account the terms of care in France, free or practicing neurologists in healthcare institutions (public or private) in different regions of France will be selected to participate in this study. The study will enroll adult patients with MS who initiated ofatumumab according to the physician's advice and independently of the study. Patients will be followed from initiation of ofatumumab either until (i) 12 months (± 1month) after initiation of ofatumumab (End of Study), or until (ii) discontinuation of treatment with ofatumumab prior to the completion of the 12-month follow-up (early termination); whichever occurs first (end of study or early termination).
