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

A Multinational, Multicenter, Randomized, Parallel-Group, Double-Blind Study to Compare the Efficacy, Tolerability and Safety of Glatiramer Acetate Injection 40 mg/ml to That of Glatiramer Acetate Injection 20 mg/ml Administered Once Daily by Subcutaneous Injection in Subjects With Relapsing Remitting (R-R) Multiple Sclerosis (MS)

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.

Inclusion Criteria:

1. Diagnosis of confirmed and documented MS defined by the Revised McDonald criteria.
2. Subjects must be of the relapsing-remitting (R-R) type.
3. Subject has experienced prior to screening at least one documented relapse in 12 months or at least 2 documented relapses in the 24 months or one documented relapse between 12 - 24 months with at least 1 documented T1-Gd enhancing lesion in the MRI performed 12 months prior screening.
4. Disease duration for at least 6 months.
5. Ambulatory with converted Kurtzke EDSS score of 0 - 5.
6. Relapse free and stable neurological condition at least for 30 days prior screening.
7. Age - 18-55 (inclusive)

Exclusion Criteria:

1. Previous use of Copaxone (glatiramer acetate)
2. Treatment with corticosteroids within 30 days prior screening or between screening and baseline.
3. Chronic corticosteroids treatment - more than 30 consecutive days.
4. Subject with any clinically significant or unstable medical condition.
5. Subjects participating in any other clinical trial (within 12 weeks prior to screening and thereafter).
6. Known history of sensitivity to Gadolinium and inability to successfully undergo MRI scanning.
