A Randomized, Double-Blind, Placebo-Controlled, Parallel Group Design Study to Evaluate the Efficacy and Safety of Teriflunomide in Reducing the Frequency of Relapses and Delaying the Accumulation of Physical Disability in Subjects With Multiple Sclerosis With Relapses

The primary objective was to determine the effect of teriflunomide on the frequency of relapses in patients with relapsing multiple sclerosis (MS).Secondary objectives were:* to evaluate the effect of teriflunomide on the accumulation of disability as measured by Expanded Disability Status Scale \[EDSS\], the burden of disease as measured by Magnetic Resonance Imaging \[MRI\] and patient-reported fatigue;* to evaluate the safety and tolerability of teriflunomide.
