Summary

This study will follow 100 adults with multiple sclerosis who are starting either teriflunomide or dimethyl fumarate as part of their routine care. Over 12 months, researchers will measure how well participants can walk and think during sustained activities, along with their reported fatigue and quality of life. The goal is to see if one drug helps more with physical and mental tiredness, helping patients and doctors make better treatment choices.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population will consist of adult patients aged 18 years or older with a confirmed diagnosis of relapsing Multiple Sclerosis (MS), including relapsing-remitting MS (RRMS) and active secondary progressive MS (SPMS), according to the 2017 revised McDonald criteria. Participants will be selected from routine clinical settings where teriflunomide has been prescribed as part of standard care. Eligible individuals must be ambulatory, with an Expanded Disability Status Scale (EDSS) score of 7.0 or lower, and capable of performing the 6-Minute Walk Test (6MWT). This population will represent a real-world cohort reflective of patients receiving teriflunomide in typical clinical practice.
