Detailed Description:

Acute ischemic stroke is a major cause of death and severe disability. There is only one approved pharmacological treatment, Alteplase, which has to be administered within 3 hours from symptom onset. Consequently, only about 2-3% of patients world wide with ischemic strokes are treated. The naturally occurring hormone, erythropoietin (EPO), is able to protect various neuronal tissues from ischemic injury and is beneficial in animal models of acute ischemic stroke. However, treatment of stroke with EPO is undesirable due to its ability to stimulate production of red blood cells and to promote the blood to coagulate. Lu AA24493 is a modified (carbamylated) version of EPO, neuroprotective but without the haematopoietic side effects. Lu AA24493 is developed for treatment of patients with acute ischemic stroke.

In this safety study of single doses with Lu AA24493, patients will receive Lu AA24493 within 12-48 hours from symptom onset.
