Copolymer 1 reduces relapse rate and improves disability in relapsing-remitting multiple sclerosis: a phase III trialOriginal paper
What was studied?
Whether copolymer 1 (glatiramer acetate) reduces relapse rate and disability in relapsing-remitting multiple sclerosis.
Who was studied?
251 people with relapsing-remitting MS randomized to glatiramer acetate 20 mg subcutaneously daily or placebo for two years at eleven centers.
What were the key findings?
The relapse rate fell 29 percent versus placebo (p = 0.007), and significantly more treated patients improved on the disability scale, with good tolerability aside from injection-site reactions.
What are the implications?
Glatiramer acetate is an effective, well-tolerated disease-modifying therapy for relapsing MS, and remains first-line decades later.
