Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
The primary objective was to demonstrate the effect of teriflunomide, in comparison to placebo, on frequency of Multiple Sclerosis (MS) relapses in patients with relapsing forms of MS who are treated with Interferon-beta (IFN-beta).

The secondary objectives were:

* Assess the effect of teriflunomide, in comparison to placebo, when added to IFN-beta on:

* Disease activity as measured by brain Magnetic Resonance Imaging (MRI)
* Disability progression
* Burden of disease and disease progression as measured by brain MRI
* Evaluate the safety and tolerability of teriflunomide when added to IFN-beta therapy
* Assess the pharmacokinetics of teriflunomide in use in addition to baseline IFN-beta therapy
* Assess associations between variations in genes and clinical outcomes (safety and efficacy)
* Assess other measures of efficacy of teriflunomide such as fatigue and health-related quality of life
* Assess measures of health economics (hospitalization due to relapse, including the length of stay and any admission to intensive care unit)
