This was a multicenter follow-up study of patients originally enrolled in the Phase 2 D2201 study. Patients did not receive any protocol specified treatment. The original D2201 study sites who agreed to participate in this study were required to locate their patients who were randomized in Study D2201 and asked them to return for a 10-year assessment, regardless of their current treatment status. Locating the patient may have required the use of search and advertising strategies to find those patients currently lost to follow-up, in accordance with local privacy legislation. Patients currently being followed within Study FTY720D2399 (NCT01201356) were asked to participate in Study FTY720D2201E2 and if patients gave consent, were enrolled concurrently in both studies.
