Brief Summary
The nature, intensity, and prevalence of this wearing-off effect remain poorly understood. To our knowledge, there is no consensus in the literature on what symptoms constitute a wearing-off effect, nor is there a single validated scale that measures wearing-off effect. The current study will explore the wearing-off effect associated with OCR and OMB, using a variety of validated scales assessing MS symptoms (i.e., fatigue, mobility, pain, depression, cognition), as well as some global questions on wearing-off. In addition, impact of worsening of MS symptoms on patients' health-related quality of life (HRQoL) and their work productivity will be assessed using relevant MS-specific validated scales

Outcome Measures
Primary Outcomes (14)
Proportion of patients who experience wearing-off effect
The wearing-off effect questionnaire for this study was modified from a pre-existing tool designed by (Toorop, et al., 2022) such that it is now suitable to assess wearing-off in patients on either infusible or self-injectable disease modifying therapies (DMTs) with different dosing intervals. There is no numeric rating scale (NRS) associated with this endpoint.
