Researchers are evaluating the clinical utility of serum neurofilament light (sNfL) as a prognostic marker for disease activity in patients with relapsing multiple sclerosis (MS). This prospective, multicenter, observational, non-interventional study in Germany aims to understand how sNfL values can influence patient management and treatment decisions. The study focuses on patients treated with category 1 disease-modifying therapies (DMTs) who have incorporated sNfL testing into their care. Participants will either continue their current category 1 DMT, which includes therapies such as dimethylfumarate, glatiramer acetate, interferon beta, and teriflunomide, or switch to ofatumumab based on their physician’s clinical judgment. There is no treatment allocation by the study itself. Data collection will cover up to 24 months, and the frequency of visits and assessments will follow routine clinical practice without a fixed protocol. During the study, baseline and follow-up data will be gathered according to standard care recommendations, including clinical evaluations and sNfL measurements. Researchers will monitor the proportion of patients with high sNfL levels over time to assess disease activity. The observational period is flexible and guided by the treating physician, with no additional diagnostic or monitoring procedures beyond standard care. Participants will be followed for up to two years to better understand how sNfL influences treatment management in relapsing MS.
