Effects of oral glatiramer acetate on clinical and MRI-monitored disease activity in patients with relapsing multiple sclerosis: a multicentre, double-blind, randomised, placebo-controlled study.
Parenterally administered glatiramer acetate reduces the frequency of relapses and the formation of active brain lesions seen with MRI in multiple sclerosis. This study assessed whether two doses of glatiramer acetate given orally could improve clinical and MRI measures of inflammation and neurodegeneration in a large cohort of patients with relapsing-remitting multiple sclerosis. ⋯ 5 mg and 50 mg glatiramer acetate administered orally on a daily basis do not affect relapse rate or other clinical and MRI parameters of disease activity and burden in patients with relapsing-remitting multiple sclerosis. Treatment with oral formulations of glatiramer acetate at the doses tested cannot be recommended.
