Title: A Multi-center, Randomized, Parallel-group, Rater-blinded Study Comparing the Effectiveness and Safety of Teriflunomide and Interferon Beta-1a in Patients With Relapsing Multiple Sclerosis Plus a Long Term Extension Period
Brief Summary: Primary objective was to assess the effectiveness evaluated by the time to failure of two doses of teriflunomide in comparison to interferon beta-1a in participants with relapsing Multiple Sclerosis \[MS\].

Secondary objectives were:

* To assess the effect of the two doses in comparison to interferon beta-1a on:

  * Frequency of relapses,
  * Fatigue,
  * Participant's satisfaction with treatment.
* To evaluate the safety and tolerability of the two doses in comparison to interferon beta-1a.

The study consisted of a core treatment period with a common end date defined as 48 weeks after randomization of the last participant, followed by an optional long-term extension treatment period until teriflunomide is commercially available in accordance with local regulations.
