Objective

Background Brain atrophy reflects tissue damage and represents an important outcome in multiple sclerosis (MS) clinical trials. Fingolimod, an oral therapy approved for relapsing MS has consistently reduced loss of brain volume (BV) in Phase 3 studies.

Design/Methods Rate of total BV loss was measured in each of three Phase 3 studies (TRANSFORMS, FREEDOMS, FREEDOMS II) using SIENA while baseline BV was measured using SIENAX. Predefined analysis of BV was by rank ANCOVA or Wilcoxon rank sum. Correlations of BV and other disease characteristics were analyzed for each study independently at baseline and during study.

Results Fingolimod significantly reduced the rate of brain atrophy compared to placebo over 2 years by 36% in FREEDOMS (-0.84 % vs. -1.31%) and 33% in FREEDOMS II (-0.86% vs. -1.28%) and over 1 year compared to interferon beta-1a IM by 31% (-0.31% vs. -0.45%) in TRANSFORMS. Effect was apparent by 6 months of treatment in placebo-controlled studies. Baseline BV correlated best with lesion volume (T2 and T1 black holes), disability (EDSS and MSFC), disease duration and age (r values ranged from 0.21 to 0.44) at baseline. High baseline T2 lesion burden and active Gd-T1 lesions were predictive of on-study BV loss. On-study BV loss correlated best with increasing numbers and volume of T2 lesions. Additional correlations of change in BV with change in clinical and MRI outcomes will be presented.

Conclusions Fingolimod consistently reduced the rate of BV loss in all Phase 3 studies. Atrophy at baseline correlated with disease severity/duration while baseline T2 volume and Gd+ lesion status was predictive of future BV loss. On-study BV loss correlated best with increasing numbers and volume of T2 lesions.
