About this study
Official title: 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.
Read the detailed description
The study period per participant was approximatively 128 weeks broken down as follows:
- Screening period up to 4 weeks,
- 108-week double-blind treatment period (approximatively 2 years)*,
- 16-week post-treatment elimination follow-up period.
'*' Participants successfully completing the week 108 visit were offered the opportunity to enter the optional long-term extension study LTS6050 - NCT00803049.

What is being measured
The primary outcome is the main question the study is designed to answer.
Annualized Relapse Rate [ARR]: Poisson Regression Estimates
ARR is obtained from the total number of confirmed relapses that occured during the treatment period divided by the sum of the treatment durations.
Each episode of relapse - appearance, or worsening of a clinical symptom that was stable for at least 30 days, that persisted for a minimum of 24 hours in the absence of fever - was to be confirmed by an increase in EDSS score or Functional System scores.
To account for the different treatment durations among participants, a Poisson regression model with robust error variance was used (total number of confirmed relapses as response variable; log-transformed treatment duration as "offset" variable; treatment group, region of enrollment and baseline EDSS stratum as covariates).
Measured: 108 weeks
Secondary outcomes (3)
Time to 12-week Sustained Disability Progression: Kaplan-Meier Estimates of the Rate of Disability Progression at Timepoints
12-week sustained disability progression was defined as an increase from baseline of at least 1-point in EDSS score (at least 0.5-point for participants with baseline EDSS score >5.5) that persisted for at least 12 weeks.
Probability of disability progression at 24, 48 and 108 weeks was estimated using Kaplan-Meier method on the time to disability progression defined as the time from randomization to first EDSS increase. Participants free of disability progression (no disability progression observed on treatment) were censored at the date of the last on-treatment EDSS evaluation.
Kaplan-Meier method consists in computing probabilities of non occurrence of event at any observed time of event and multiplying successive probabilities for time ≤t by any earlier computed probabilities to estimate the probability of being event-free for the amount of time t. Probability of event at time t is 1 minus the probability of being event-free for the amount of time t.
Measured: 108 weeks
Cerebral Magnetic Resonance Imaging [MRI] Assessment: Change From Baseline in Total Lesion Volume (Burden of Disease)
Total lesion volume is the sum of the total volume of all T2-lesions and the total volume all T1-hypointense post-gadolinium lesions measured through T2/proton density scan analysis and gadolinium-enhanced T1 scan analysis.
Measured: baseline (before randomization) and 108 weeks
Changes From Baseline in Fatigue Impact Scale [FIS] Total Score
FIS is a subject-reported scale that qualifies the impact of fatigue on daily life in patients with MS. It consists of 40 statements that measure fatigue in three areas; physical, cognitive, and social.
FIS total score ranges from 0 (no problem) to 160 (extreme problem).
Least-square means were estimated using a Mixed-effect model with repeated measures [MMRM] on FIS total score data (treatment group, region of enrollment, baseline EDSS stratum, visit, treatment-by-visit interaction, baseline value, and baseline-by-visit interaction as factors).
Measured: baseline (before randomization) and 108 weeks

Primary outcome
Annualized Relapse Rate [ARR]: Poisson Regression Estimates
Time frame: 108 weeks
ARR is obtained from the total number of confirmed relapses that occured during the treatment period divided by the sum of the treatment durations. Each episode of relapse - appearance, or worsening of a clinical symptom that was stable for at least 30 days, that persisted for a minimum of 24 hours in the absence of fever - was to be confirmed by an increase in EDSS score or Functional System scores. To account for the different treatment durations among participants, a Poisson regression model with robust error variance was used (total number of confirmed relapses as response variable; log-transformed treatment duration as "offset" variable; treatment group, region of enrollment and baseline EDSS stratum as covariates).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Teriflunomide in people with Multiple Sclerosis, run by Sanofi at 21 sites in 21 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 21 sites in United States, Austria, Canada, Chile, Czechia and 16 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 6 Nov 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Annualized Relapse Rate [ARR]: Poisson Regression Estimates (time frame: 108 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00134563, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Jan 2013; AzTrials last refreshed its copy on 8 Nov 2026.
