Study to Evaluate Fatigue in Participants With Relapsing Remitting Multiple Sclerosis When Treated With Dimethyl Fumarate

Summary

The primary objective of this study is to determine whether dimethyl fumarate (DMF) taken over 12 months is effective in reducing Multiple Sclerosis (MS)-related fatigue, as measured by mean changes in the Fatigue Scale for Motor and Cognitive Functions (FSMC), in participants with relapsing-remitting multiple sclerosis (RRMS). The secondary objectives of this study are: To investigate changes from Baseline in FSMC and fatigue severity (Fatigue Severity Scale \[FSS\]) at 1, 3, 6, 9, and 12 months in participants receiving DMF; To assess the impact of DMF on patient-reported outcomes (PROs), including work productivity (Work Productivity and Activity Impairment-Multiple Sclerosis questionnaire \[WPAI-MS\]), health-related quality of life (Short Form Health Survey \[SF-12\]), depression (Beck Depression Inventory-Fast Screen \[BDI-FS\]), and sleepiness (Epworth Sleepiness Scale \[ESS\]) at 6 and 12 months in participants receiving DMF; To examine whether an association exists between fatigue and baseline demographics (e.g., age and sex) and disease characteristics (e.g., disease duration, baseline disease activity, treatment history, expanded disability status scale \[EDSS\] score, and PROs); To assess any changes in fatigue-related medication use.
