About this study

Official title: A Randomized, Multinational, Double-blind, Placebo-controlled, Parallel-group Design Pilot Study to Estimate the Tolerability, Safety, Pharmacokinetics, and Pharmacodynamic Effects of Teriflunomide for 24 Weeks When Added to Treatment With Glatiramer Acetate in Subjects With Multiple Sclerosis

The primary objective was to estimate the tolerability and safety of 2 doses of Teriflunomide administered once daily for 24 weeks, compared to placebo, in patients with multiple sclerosis [MS] with relapses who were on a stable dose of Glatiramer Acetate [GA].

The secondary objectives were:

  • to estimate the effect of the 2 doses of Teriflunomide, compared to placebo, in combination with a stable dose of GA on Magnetic Resonance Imaging [MRI] parameters, relapse rate and patient-reported fatigue;
  • to perform pharmacokinetic analyses of the 2 doses of teriflunomide in combination with a stable dose of GA.
Read the detailed description

The duration of the study period for a participant was approximatively 44 weeks broken down as follows:

  • Screening period up to 4 weeks,
  • 24-week double-blind treatment period*,
  • 16-week post-treatment elimination follow-up period.

'*' Participants successfully completing the week 24 visit were offered the opportunity to enter the optional long-term extension study LTS6047 - NCT00811395.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Overview of Adverse Events (AE]

    AE are any unfavorable and unintended sign, symptom, syndrome, or illness observed by the investigator or reported by the participant during the study.

    Measured: from first study drug intake up to 112 days after last intake or up to the first intake in the extension study LTS6047, whichever occured first (40 weeks max)

  2. Overview of AE With Potential Risk of Occurrence

    AE with potential risk of occurrence were defined as follows:

    • Hepatic disorders;
    • Immune effects, mainly effects on bone marrow and infection;
    • Pancreatic disorders;
    • Malignancy;
    • Skin disorders, mainly hair loss and hair thinning;
    • Pulmonary disorders;
    • Hypertension;
    • Peripheral neuropathy;
    • Psychiatric disorders;
    • Hypersensitivity.

    Measured: from first study drug intake up to 112 days after last intake or up to the first intake in the extension study LTS6047, whichever occured first (40 weeks max)

  3. Liver Function: Number of Participants With Potentially Clinically Significant Abnormalities (PCSA)

    PCSA values are abnormal values considered medically important by the Sponsor according to predefined criteria based on literature review.

    Hepatic parameters thresholds were defined as follows:

    • Alanine Aminotransferase [ALT] >3, 5, 10 or 20 Upper Normal Limit [ULN];
    • Aspartate aminotransferase [AST] >3, 5, 10 or 20 ULN;
    • Alkaline Phosphatase >1.5 ULN;
    • Total Bilirubin [TB] >1.5 or 2 ULN;
    • ALT >3 ULN and TB >2 ULN.

    Measured: from first study drug intake up to 112 days after last intake or up to the first intake in the extension study LTS6047, whichever occured first (40 weeks max)

Secondary outcomes (5)
  1. 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.

    Least-square means were estimated using a Mixed-effect model with repeated measures [MMRM] on cubic root transformed volume data (treatment group, region of enrollment, visit, treatment-by-visit interaction, baseline value (cubic root transformed), and baseline-by-visit interaction as factors).

    Measured: baseline (before randomization) and 24 weeks

  2. Cerebral MRI Assessment: Number of Gd-enhancing T1-lesions Per Scan (Poisson Regression Estimates)

    Number of Gd-enhancing T1-lesions per scan is obtained from the total number of Gd-enhancing T1-lesions observed during the study divided by the total number of scans performed during the study.

    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 and baseline number of Gd-enhancing T1-lesions as covariates).

    Measured: 24 weeks

  3. Cerebral MRI Assessment: Volume of Gd-enhancing T1-lesions Per Scan

    Total volume of Gd-enhancing T1-lesions per scan is obtained from the sum of the volumes of Gd-enhancing T1-lesions observed during the study divided by the total number of scans performed during the study.

    Measured: 24 weeks

  4. 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 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 and region of enrollment as covariates).

    Measured: 24 weeks

  5. Pharmacokinetic [PK]: Teriflunomide Plasma Concentration

    Plasma concentrations of teriflunomide were measured using validated liquid chromatography-tandem mass spectrometry methods.

    Measured: 24 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Teriflunomide and Glatiramer Acetate (GA) in people with Multiple Sclerosis, run by Sanofi at 6 sites in 6 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 7 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 6 Nov 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States, Austria, Canada, Germany, Italy and 1 more country. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 2 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?

Overview of Adverse Events (AE] (time frame: from first study drug intake up to 112 days after last intake or up to the first intake in the extension study LTS6047, whichever occured first (40 weeks max)). The study lists 3 primary outcomes in all. 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 NCT00475865, which also lists 1 linked publication.

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 6 Nov 2012.
