This Was an Open-label, Single-arm Extension Study (CFTY720D2306E1) to a Double-blind, Randomized Multicenter, Placebo-controlled, Parallel-group Core Study (CFTY720D2306) in PPMS.

The purpose of this study is to evaluate whether FTY720 is effective in delaying MS disability progression compared to placebo in patients with PPMS. This was an open-label, single-arm extension study to a double-blind, randomized multicenter, placebo-controlled, parallel-group core study. The core study completed and eligible patients enrolled into the extension study at the next scheduled or unscheduled core study visit. All patients, regardless of their treatment in the core study, received fingolimod 0.5 mg in the extension study. The extension study was terminated early after the results of the core study became available showing that the study did not meet its primary endpoint which was defined as confirmed disability progression in this population
