About this study

Official title: A Multinational, Multicenter, Randomized, Double-Blind, Placebo Controlled, Parallel Group Study to Evaluate the Effect of Early Glatiramer Acetate Treatment in Delaying the Conversion to Clinically Definite Multiple Sclerosis (CDMS) of Subjects Presenting With Clinically Isolated Syndrome (CIS)

The primary objective is to assess the effect of treatment with glatiramer acetate (GA) compared to placebo on the time to conversion to CDMS, as determined by Poser criteria (the occurrence of the second clinical attack) during the double-blind period. The secondary objective is to assess, within the time frame of the up to 3-year double-blind, placebo-controlled study period, the effect of GA on clinical and Magnetic Resonance Imaging (MRI) parameters. The long-term objectives of the study (exploratory in nature) are to assess, within the time frame of 5 years, the neuroprotective effect of early versus delayed treatment with GA as reflected by clinical and MRI parameters measuring the accumulated irreversible brain tissue damage.

A pre-planned interim analysis was performed on all efficacy and safety data accumulated in the database up to October 14, 2007, i.e. when 81% of exposure to treatment in the double-blind, placebo-controlled period had been collected. Upon review of the interim analysis results, the Data Monitoring Committee (DMC) recommended that the double-blind portion of the study be stopped and that subjects be switched to the 2-year Open-label period, during which time they would have the option of receiving GA therapy. The sponsor (Teva) adopted the DMC recommendations and took the necessary action towards its implementation.

What is being measured

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

  1. Time to Clinically Definite Multiple Sclerosis (CDMS) Conversion

    Data from interim analysis with database lock on October 14, 2007. The time from randomization to conversion to CDMS as determined by the occurrence of a second clinical attack during the double-blind period. Poser criteria are: Two relapses and clinical evidence of two separate lesions; clinical evidence of one lesion and paraclinical evidence of another separate lesion. The two relapses must involve different parts of Central Nervous System and must be separated by a period of at least one month. Lesions are determined by Magnetic Resonance Imaging (MRI).

    Measured: up to 3 years

  2. Twenty-fifth Percentile (25%) Kaplan-Meier Estimates for Time From Randomization to Conversion to Clinically Definite Multiple Sclerosis (CDMS) During the Double-blind Period

    Data from interim analysis with database lock on October 14, 2007. Due to the number of participants in the glatiramer acetate group that converted to CDMS (see outcome #6), the 25th percentile was considered when running the Kaplan-Meier estimate for time to conversion to CDMS. Conversion to CDMS is determined by the occurrence of the second clinical attack.

    Measured: up to 3 years

Secondary outcomes (4)
  1. Number of New T2 Brain Lesions Observed at the Last Observed Value (LOV) in the Double-blind Period

    Data from interim analysis with database lock on October 14, 2007. T2 lesions are brain lesions that show on magnetic resonance imaging (MRI) and are associated with multiple sclerosis. This outcome measures the number of new lesions at the last observed value. Last Observed Value (LOV) is defined as the last post baseline measurement taken on study drug but no more than 30 days after study drug cessation.

    Measured: up to 3 years

  2. Change From Baseline to Last Observed Value (LOV) in T2 Brain Lesion Volume in the Double-blind Period

    Data from interim analysis with database lock on October 14, 2007. The difference in T2 brain lesion volume as observed in MRIs from baseline to the last observed value. Last Observed Value (LOV) is defined as the last post baseline measurement taken on study drug but no more than 30 days after study drug cessation.

    Measured: Day 0 (baseline), up to 3 years

  3. Percentage Change in Brain Volume From Baseline to the Last Observed Value (LOV) During the Double-blind Period Using the Structural Image Evaluation of Normalized Atrophy (SIENA) Technique

    Data from interim analysis with database lock on October 14, 2007. Brain volume was measured annually by magnetic resonance imaging (MRI) during the Double-blind period. Brain atrophy was measured by comparing the change in brain volume from baseline to the Last Observed Value (LOV). LOV is defined as the last post baseline measurement taken on study drug but no more than 30 days after study drug cessation. SIENA is a fully automated method of analyzing longitudinal brain change.

    Measured: Day 0 (baseline), up to 3 years

  4. Percentage of Participants Who Converted to Clinically Definite Multiple Sclerosis (CDMS) During the Double-blind Period

    Data from interim analysis with database lock on October 14, 2007. Conversion to CDMS as determined by the occurrence of a second clinical attack during the double-blind period. Poser criteria are: Two relapses and clinical evidence of two separate lesions; clinical evidence of one lesion and paraclinical evidence of another separate lesion. The two relapses must involve different parts of Central Nervous System and must be separated by a period of at least one month. Lesions are determined by Magnetic Resonance Imaging (MRI).

    Measured: up to 3 years
