LYON, FRANCE—Data from a phase III trial support the efficacy of a new dosing regimen for Copaxone (glatiramer acetate) for patients with relapsing-remitting multiple sclerosis (MS).
Teva Pharmaceutical Industries released data from the Glatiramer Acetate Low-Frequency Administration (GALA) study, which was designed to evaluate the efficacy, safety, and tolerability of 40 mg/mL of glatiramer acetate three times weekly instead of the 20-mg/mL daily subcutaneous injection that has been the recommended dose for almost two decades.
In the GALA study, a one-year, randomized, double-blind, placebo-controlled trial, glatiramer acetate 40 mg/mL injected three times weekly significantly reduced annualized relapse rates by 34.4% versus placebo. The cumulative number of new and enlarging T2 lesions was significantly reduced by the same percentage. In addition, a significant 44.8% reduction in the cumulative number of gadolinium-enhancing lesions was observed in patients treated with the investigational dosing regimen. At 12 months, there was no significant difference in percentage change of brain volume between the glatiramer acetate-treated patients and those receiving placebo. Discontinuation rates among the two cohorts were comparable.
