Brief summary
The purpose of this trial is to evaluate the effects of Rebif® 44 mcg subcutaneous (sc) three times a week (tiw) on a) remyelination/demyelination, b) lesion and brain volume, c) central nervous system (CNS) iron deposition, and d) immune status in subjects with relapsing-remitting multiple sclerosis (RRMS) RRMS via several MRI techniques.

Outcome results
Change in Volume (in Millimeters Cubed) of Normal Appearing Brain Tissue (NABT) With Increasing (Indicative of Remyelination) Voxel-wise Magnetization Transfer Ratio (VW-MTR) From Baseline to 6 Months
To characterize the effect of Rebif on remyelination using VW-MTR dynamic mapping of NABT in subjects ith RRMS over 6 months of treatment compared to a group of healthy Control (HC).
Time frame: Baseline to Month 6
Population: The analysis were run on the Intent-to-Treat (ITT) set defined as all RRMS subjects with at least one injection of Rebif and all HC who signed the informed consent form. Missing data were not imputed.
