  Purpose

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.

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

Primary Outcome Measures:
  • 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) ] [ Designated as safety issue: Yes ]
    AE are any unfavorable and unintended sign, symptom, syndrome, or illness observed by the investigator or reported by the participant during the study.

  • Overview of AE With Potential Risk of Occurrence [ 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) ] [ Designated as safety issue: Yes ]

    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.

  • Liver Function: Number of Participants With Potentially Clinically Significant Abnormalities (PCSA) [ 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) ] [ Designated as safety issue: Yes ]

    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.


Secondary Outcome Measures:
  • Cerebral Magnetic Resonance Imaging [MRI] Assessment: Change From Baseline in Total Lesion Volume (Burden of Disease) [ Time Frame: baseline (before randomization) and 24 weeks ] [ Designated as safety issue: No ]

    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).


  • Cerebral MRI Assessment: Number of Gd-enhancing T1-lesions Per Scan (Poisson Regression Estimates) [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]

    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).


  • Cerebral MRI Assessment: Volume of Gd-enhancing T1-lesions Per Scan [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
    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.

  • Annualized Relapse Rate [ARR]: Poisson Regression Estimates [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]

    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).


  • Pharmacokinetic [PK]: Teriflunomide Plasma Concentration [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
    Plasma concentrations of teriflunomide were measured using validated liquid chromatography-tandem mass spectrometry methods.
