Title: A Multi-center Double-blind Parallel-group Placebo-controlled Study of the Efficacy and Safety of Teriflunomide in Patients With Relapsing Multiple Sclerosis
Brief Summary: The primary objective of the study was to assess the effect of two doses of teriflunomide, in comparison to placebo, on the frequency of multiple sclerosis (MS) relapses in participants with relapsing MS.

Key secondary objective was to assess the effect of the two doses of teriflunomide, in comparison to placebo, on disability progression.

Other secondary objectives were:

* To assess the effect of the two doses of teriflunomide in comparison to placebo on:

  * Fatigue;
  * Health-related quality of life, a measure of the impact of the participant's health on his or her overall well being.
* To evaluate the safety and tolerability of teriflunomide.
