Long-term Follow up of Patients With Relapsing-remitting Multiple Sclerosis Enrolled in the Multicenter, Single-arm, Open-label Biobank Study (CFTY720DDE01), to Investigate Changes in Biomarkers After 48 Months of Treatment With 0.5 mg Fingolimod (FTY720)

The purpose of this single visit extension study is to explore immune status in RRMS patients treated for at least 48 months with fingolimod. Long-term changes in T cell counts will be compared to short-term changes in immune status (baseline to month 6) after treatment start with fingolimod as assessed in the original Biobank study (CFTY720DDE01).

Inclusion Criteria:

1. Written informed consent before any assessment was performed.
2. Randomized in study CFTY720DDE01 and received at least one dose of study drug (fingolimod) and completed the study.
3. Continuous intake of fingolimod after end of study CFTY720DDE01 with a maximum treatment interruption of 3 months in total before entering this study.
4. Parallel participation at study CFTY720DDE02 (Pangaea NIS) was allowed.

Exclusion criteriat:

1. Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive human Chorionic Gonadotropin (hCG) laboratory test.
2. Patients with onset of an acute relapse had to postpone their evaluation until deemed stable from relapse by treating physician, but at least for 1 month since end of relapse.
3. Patients that received immunomodulating or immunosuppressive MS treatments other than fingolimod since completion of study CFTY720DDE01 as for example: Natalizumab,Alemtuzumab, Dimethyl fumarate, Teriflunomide, intravenous Immunoglobulins,Mitoxantrone, Methotrexate, Azathioprine or experimental immunomodulating-immunosuppressive therapies.
