Brief summary
The purpose of this randomized, double-blind, placebo-controlled multicenter study is to determine in a cohort of 506 patients with acute ischemic stroke in the middle cerebral artery territory, the effect of a three-day high-dose, intravenous erythropoietin treatment on functional outcome up to a follow-up of 90 days.
Interventions
40,000 IU in 50ml 0.9% NaCl iv on 3 consecutive days, starting within 6 hours after onset of symptoms
50ml 0.9% NaCl iv on 3 consecutive days, starting within 6 hours after onset of symptoms
