Exploratory Study to Assess Clinical Response to Gilenya® (Fingolimod) in Hispanics With RRMS

The primary objective of this study is to determine the success of Gilenya® (fingolimod) treatment in patients with MS of Hispanic descent relative to their ancestral background. Therapeutic success will be determined by annualized relapse rate (ARR; defined as the number of relapses divided by the person years followed) after initiation of treatment with Gilenya® (fingolimod)in comparison to the relapse rate in the previous 12 months. This will be determined based on medical chart extraction, in-person assessment and regular clinical follow-up. A secondary objective of this study is to investigate whether the efficacy of Gilenya® (fingolimod) is superior or equal in HW which have higher loads of Amerindian versus Caucasian background with opticospinal MS (OSMS-NMO neg) versus classical MS (CMS) in the first 12 months using radiological and clinical parameters. The following measures will be obtained: 1. Number of relapse-free patients over the investigational period 2. Site of relapse defined as brain or spinal cord. 3. Sustained Disability progression will be defined as a one point (1) increase from baseline in patients with baseline EDSS score from 0 to 5.0; or half a point (0.5) increase in patients with baseline EDSS score of 5-5.5 or above after 3 months. 4. MRI changes as described as number of new T2 lesions and number of Gd-enhancing lesions after 12 months from baseline.
