Outcome Measures
Primary Outcomes (1)
Reductions in the Annualized relapse rate (ARR)
ARR, defined as the total number of confirmed relapses that occurred during the observation period divided by the total number of patient-years, with the result standardized to a 1-year period. A relapse is defined as new or recurrent symptoms and objective typical findings of MS with a duration of at least 24 h, in the absence of fever or infection and preceded by a stable or improving neurological state for ≥ 30 days
12 months preceding the initiation of ofatumumab, Baseline
Secondary Outcomes (18)
Reductions in the ARR in naïve vs previously treated patients
12 months preceding the initiation of ofatumumab, Baseline
Reductions in the ARR in previously treated with high-efficacy Disease-modifying treatments (DMT) vs previously treated with moderate-efficacy DMT
12 months preceding the initiation of ofatumumab, Baseline
Number of days from ofatumumab treatment initiation to first relapse
