  Purpose

The primary objective of this study is to document the long-term safety and tolerability of teriflunomide in Multiple Sclerosis (MS) patients with relapse.

The secondary objective is to document the long-term efficacy on disability progression, relapse rate and Magnetic Resonance Imaging (MRI) parameters.

Primary Outcome Measures:
  • Number of patients with adverse events [ Time Frame: Up to a maximum of 292 weeks (4 weeks after last treatment intake) or until teriflunomide is commercially available in the country where patient lives ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Time to disability progression as assessed by Expanded Disability Status Scale (EDSS) [ Time Frame: Up to a maximum of 288 weeks or until teriflunomide is commercially available in the country where patient lives ] [ Designated as safety issue: No ]
  • Proportion of patients free of disability progression [ Time Frame: Up to a maximum of 288 weeks or until teriflunomide is commercially available in the country where patient lives ] [ Designated as safety issue: No ]
  • Annualized relapse rate (number of confirmed relapses per patient-year) [ Time Frame: Up to a maximum of 288 weeks or until teriflunomide is commercially available in the country where patient lives ] [ Designated as safety issue: No ]
  • Burden of disease : Change from baseline in the volume of abnormal brain tissue as measured by brain MRI [ Time Frame: Up to a maximum of 288 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment: 1080
Study Start Date: October 2006
Estimated Study Completion Date: February 2016

Arms Assigned Interventions
Experimental: Teriflunomide 7 mg Drug: teriflunomide (HMR1726)
Tablet, oral administration once daily.
Experimental: Teriflunomide 14 mg Drug: teriflunomide (HMR1726)
Tablet, oral administration once daily.

Detailed Description:

Patients completing the EFC6049 (HMR1726D/3001) study are given the opportunity to continue in the extension study;

  • patients receiving teriflunomide 7 mg or 14 mg are blindly maintained on the same dose of teriflunomide.
  • patients receiving placebo are randomized to teriflunomide 7 mg or 14 mg.

The study period per patient is broken down as follows:

  • Double-blind treatment: up to a maximum of 288 weeks or until teriflunomide is commercially available in the country where patient lives,
  • Post-washout follow-up: 4 weeks after last treatment intake. No post-washout follow up if patient continues on teriflunomide treatment by obtaining it's commercial form after end of the study.

The total duration of the extension is 292 weeks (about 6 years) from the first patient enrolled or until teriflunomide is commercially available in the country where patient lives.
