Study Description

This is a prospective, multicenter, observational, non-interventional study (NIS) in patients with Multiple Sclerosis (MS) and routinely assessed serum neurofilament light (sNfL) values in Germany Prospective, primary data will be collected from patients with sNfL outcomes in the context of switching to ofatumumab or continuing their current therapy. Data collection will cover a maximum period of 24 months.

The observational period will not be dictated by the protocol. Baseline and follow-up visits will take place at a frequency defined as per Investigator´s discretion following clinical routine. The diagnostic or monitoring procedures are only those ordinarily applied to therapeutic strategy and routine clinical care. During the observation phase of the study, data will be collected according to standard of care as recommended by KKNMS (Competence Network Multiple Sclerosis in Germany).

Eligible participants for the study are patients who have received treatment with category 1 DMTs and those who have included sNfL into their treatment decision-making process. These patients have the option to either continue their current DMT or switch to ofatumumab. According to local treatment guidelines, DMT category 1 include dimethylfumarate/diroximelfumarate, glatirameroids, Interferon beta and teriflunomide. The decision to switch to ofatumumab or to continue the current DMT category 1 therapy must be made by the treating physician independently of the decision to enroll the patient in the study.
