Clinical Trial Comparing Treatment of Relapsing-Remitting Multiple Sclerosis (RR-MS) With Two Doses of Glatiramer Acetate (GA).

• The Number of New T2 Lesions at Month 12 as Compared to the Baseline Scan. [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  The analysis of this endpoint was based on the outcome of a contrast derived from a baseline-adjusted Negative Binomial Regression including the number of T1 Gd-enhancing lesions at baseline, the volume of T2 lesions at baseline and (pooled) center as covariates.
• The Cumulative Number of T1-Gd Enhancing Lesions at Months 3, 6, 9 and 12 (in the Frequent MRI Cohort-described Below). [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  The Frequent MRI Cohort was a subset of subjects consisting of 234 subjects, for whom MRI scans were performed at months 0 (baseline), 1, 2, 3, 6, 9 and 12. Analysis of the endpoint was based on the outcome of a contrast derived from a baseline-adjusted Negative Binomial Regression with an "offset" variable employing the log of the porportion of the number of available post-baseline scans to adjust for missing MRI scans (if any) and including the number of T1 Gd-enhancing lesions at baseline and (pooled) center as covariates.

• The time to the first confirmed relapse
• The proportion (%) of subjects who relapsed
• The number of new T2 lesions at termination as compared to baseline MRI scan
• The total number of T1-Gd enhancing lesions at months 3, 6, 9 and 12 (Frequent MRI Cohort)

Teva is developing a 40 mg/ml GA Injection, administered once daily under the skin, for the treatment of R-R MS. The study drug is a higher dose formulation of Copaxone® (20 mg/ml GA), a marketed medication, approved for the treatment of R-R MS. GA is an immunomodulating drug that has anti inflammatory and neuroprotective properties. The study treatment duration is 12 months.
