Multiple Sclerosis Relapse

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)

Detailed description

The study period per patient was expected to be between 56 and 160 weeks depending on when the patient was randomized and this included the following: * a screening period up to 4 weeks, * a treatment period expected to be between 48 and 152 weeks, * 4-week post rapid elimination follow-up period. Patients were to continue on treatment until a fixed common end date which was approximately 48 weeks after randomization of the last patient. For those patients who completed the treatment period, a long term extension study of approximately 1 year (including teriflunomide alone) was initially planned to be proposed.

Design outcomes

Primary

MeasureTime frameDescription
Annualized Relapse Rate (ARR) (Poisson Regression Estimates)Up to a maximum of 108 weeks depending on time of enrollmentARR is the total number of confirmed relapses that occurred during the treatment period divided by the total number of patient-years treated. 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 Expanded Disability Status Scale (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 IFN-beta dose stratum, and number of relapses in the year prior to randomization as covariates).

To account for the different number of scans among participants, a Poisson regression model with robust error variance was used (total number of Gd-enhancing T1-lesions as response variable; log-transformed number of scans as offset variable; treatment group, region of enrollment, IFN-beta dose stratum and baseline number of Gd-enhancing T1-lesions as covariates).
Time to 12-Week Sustained Disability ProgressionUp to a maximum of 108 weeks depending on time of enrollmentThe 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 was to be estimated using Kaplan-Meier method.
Brain MRI Assessment: Volume of Gd-enhancing T1-lesions Per MRI ScanUp to a maximum of 108 weeks depending on time of enrollmentTotal volume of Gd-enhancing T1-lesions per scan is the sum of the volumes of Gd-enhancing T1-lesions observed during the treatment period divided by the total number of scans performed during the treatment period.
Brain MRI Assessment: Change From Baseline in Total Lesion Volume (Burden of Disease) at Week 24Baseline, Week 24The total lesion volume (burden of disease) is the total volumes of hyperintense on T2 plus hypointense on T1 as measured by MRI scan. Least-square means were estimated using a Mixed-effect model with repeated measures (MMRM) on cubic root transformed volume data with factors for treatment, region, IFN-beta dose stratum, visit, treatment-by-visit interaction, cubic root transformed baseline burden of disease, and baseline-by-visit interaction.

Overview of Adverse Events (AEs)First study drug intake up to 28 days after last study drug intake, for up to 112 weeksAEs are any unfavorable and unintended sign, symptom, syndrome, or illness observed by the investigator or reported by the participant during the study.
Time to Relapse: Kaplan-Meier Estimates of the Probability of no Relapse at Week 24, 48, and 72Up to a maximum of 108 weeks depending on time of enrollmentProbability of no relapse at 24, 48 and 72 weeks was estimated using Kaplan-Meier method on the time to relapse defined as the time from randomization to first EDSS confirmed relapse. Participants free of confirmed relapse (no EDSS confirmed relapse observed on treatment) were censored at the date of the last study drug intake. 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.

A total of 846 participants were screened at 185 sites in 28 countries.

Pre-assignment details

Randomization was stratified by investigational site and Interferon-beta (IFN-beta) dose level (high/low). Assignment to groups was done centrally using an Interactive Voice Response System (IVRS) in a 1:1:1 ratio after confirmation of selection criteria. A total of 534 participants were randomized.
