A Multinational, Multicenter, Randomized, Parallel-group Study Performed in Subjects With Relapsing-Remitting Multiple Sclerosis (RRMS) to Assess the Efficacy, Safety and Tolerability of Glatiramer Acetate (GA) Injection 40 mg Administered Three Times a Week Compared to Placebo in a Double-blind Design
A Multinational, Multicenter, Randomized, Parallel-group Study Performed in Subjects With Relapsing-Remitting Multiple Sclerosis (RRMS) to Assess the Efficacy, Safety and Tolerability of Glatiramer Acetate (GA) Injection 40 mg Administered Three Times a Week Compared to Placebo in a Double-blind Design
The study is designed to assess the efficacy of Glatiramer Acetate (GA) injection 40 mg administered three times a week compared to placebo in subjects with RRMS, as measured by the number of confirmed relapses during the 12 month placebo controlled period. The study has two periods:
Participants who were randomized to the GA 40 mg treatment arm in the Double-Blind Period, continue that treatment in the Open-Label Extension Period and are referred to as "Early Start" participants. Participants randomized to the Placebo arm in the Double-Blind Period and switched to GA 40 mg subcutaneous injections three times a week in the Open-Label Extension are referred to as "Delayed Start" participants.
