A novel role for an established player: anemia drug erythropoietin for the treatment of cerebral hypoxia/ischemia.

Erythropoietin, a hematopoietic growth-factor possessing manifold, potent neuroprotective properties, after multiple testing in cell culture and animal studies now gradually finds its way into clinical neuroscience. The first time this took place was in 1998 with a pilot study in stroke patients, the "Göttingen EPO-Stroke-Trial". This study was able to demonstrate that EPO is perfectly well tolerated and safe with this indication. Furthermore, the EPO-treated patients showed a significantly better outcome regarding their clinical progress as well as regarding the infarct size as observed by MRI, when compared to the placebo treated patients. At the moment a multicenter study is being carried out in Germany.
