Phase III Study With Teriflunomide Versus Placebo in Patients With First Clinical Symptom of Multiple Sclerosis

Summary

The primary objective was to demonstrate the effect of teriflunomide (HMR1726) (14 milligram per day \[mg/day\] and 7 mg/day), in comparison to placebo, for reducing conversion of participants presenting with their first clinical episode consistent with multiple sclerosis (MS) to clinically definite multiple sclerosis (CDMS). The secondary objectives were: * To demonstrate the effect of teriflunomide, in comparison to placebo, on: * Reducing conversion to definite multiple sclerosis (DMS) * Reducing annualized relapse rate (ARR) * Reducing disease activity/progression as measured by Magnetic Resonance Imaging (MRI) * Reducing accumulation of disability for at least 12 weeks as measured by the Expanded Disability Status Scale (EDSS) * Proportion of disability-free participants as assessed by the EDSS * Reducing participant-reported fatigue * To evaluate the safety and tolerability of teriflunomide * To evaluate the pharmacokinetics (PK) of teriflunomide * Optional pharmacogenomic testing aimed at assessing the association between the main enzyme systems of teriflunomide metabolism and hepatic safety, and other potential associations between gene variations and clinical outcomes
