A Randomized, Double-blind, Placebo-controlled, Multicenter Study of the Effects of Glatiramer Acetate (GA) on the Retinal Nerve Fiber Layer (RNFL) and Visual Function in Patients With a First Episode of Acute Optic Neuritis (AON)

Status: Completed
Intervention Type: Drug
Study Type: Interventional
Study Phase: Phase 3

The main objective of the study is to determine whether glatiramer acetate 20 mg once daily reduces the amount of axonal loss in the optic nerve after a first event of acute optic neuritis compared to placebo patients and to generate data supporting the potential neuroprotective effect of glatiramer acetate in a human in vivo model of axonal loss.
