4.Secondary Outcome
Title Cerebral Magnetic Resonance Imaging [MRI] Assessment: Change From Baseline in Total Lesion Volume (Burden of Disease)
Hide Description

Total lesion volume is the sum of the total volume of all T2-lesions and the total volume all T1-hypointense post-gadolinium lesions measured through T2/proton density scan analysis and gadolinium-enhanced T1 scan analysis.

Least-square means were estimated using a Mixed-effect model with repeated measures [MMRM] on cubic root transformed volume data (treatment group, region of enrollment, visit, treatment-by-visit interaction, baseline value (cubic root transformed), and baseline-by-visit interaction as factors).

Title Cerebral MRI Assessment: Number of Gd-enhancing T1-lesions Per Scan (Poisson Regression Estimates)
Hide Description

Number of Gd-enhancing T1-lesions per scan is obtained from the total number of Gd-enhancing T1-lesions observed during the study divided by the total number of scans performed during the study.

To account for the different number of scans among participants, a Poisson regression model with robust error variance was used (total number of Gd-enhancing T1-lesions as response variable; log-transformed number of scans as "offset" variable; treatment group, region of enrollment and baseline number of Gd-enhancing T1-lesions as covariates).

Title Annualized Relapse Rate [ARR]: Poisson Regression Estimates
Hide Description

ARR is obtained from the total number of confirmed relapses that occured during the treatment period divided by the sum of the treatment durations.

Each episode of relapse - appearance, or worsening of a clinical symptom that was stable for at least 30 days, that persisted for a minimum of 24 hours in the absence of fever - was to be confirmed by an increase in Expanded Disability Status Scale [EDSS] score or Functional System scores.

To account for the different treatment durations among participants, a Poisson regression model with robust error variance was used (total number of confirmed relapses as response variable; log-transformed treatment duration as "offset" variable; treatment group and region of enrollment as covariates).
