Inclusion criteria

Inclusion criteria: - Patients who have completed the last study visit of the previous study (EFC6049) and do not meet criteria for treatment withdrawal - Female patients of childbearing potential must agree to comply with the contraception requirement described in section 7.4 of the protocol. - Female patients have demonstrated not to be pregnant by serum pregnancy test or breast feeding at the time of study entry. - McDonald's criteria must continue to support the diagnosis of clinically definite MS (see protocol appendix A). - An informed consent must be obtain in writing from the patient for this extension study prior to enrollment. Patients must demonstrate a willingness and ability to participate in a long term safety and efficacy trial with the opportunity to continue treatment on either 7 mg or 14 mg/day of teriflunomide under double-blind conditions, until availability of the results for study EFC6049 (HMR1726D/3001). Patients must actively refuse existing approved therapies. In addition a supplemental HIV-testing informed consent will be required for patients who have not yet signed it in the main study (EFC6049) in order to have an HIV testing at baseline and yearly. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 1080 F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range

Design outcomes

Primary

MeasureTime frame
Main Objective: To document the long-term safety and tolerability of two doses of teriflunomide (7 and 14 mg) in MS patients with relapses. ;Secondary Objective: To document the long-term effect on disability progression (key secondary endpoint), annual relapse rate and MRI variables.;Primary end point(s): The primary endpoint is the safety of teriflunomide. Number of patients with adverse events;Timepoint(s) of evaluation of this end point: Up to a maximum of 336 weeks (+ 4-week follow-up period).

Secondary

MeasureTime frame
Timepoint(s) of evaluation of this end point: Up to a maximum of 336 weeks.; Secondary end point(s): 1) Time to disability progression as assessed by Expanded Disability Status Scale (EDSS) 2) Proportion of patients free of disability progression 3) Annualized relapse rate (number of confirmed relapses per patientyear) 4) Burden of disease : Change from baseline in the volume of abnormal brain tissue as measured by brain MRI
