Although EPO has been considered to be a safe and well-tolerated drug over 2 decades, recent studies have identified increased thromboembolic complications and/or mortality risks on EPO administration to patients with cancer or chronic kidney disease. Accordingly, the double-blind, placebo-controlled, randomized German Multicenter EPO Stroke Trial (Phase II/III; ClinicalTrials.gov Identifier: NCT00604630) was designed to evaluate efficacy and safety of EPO in stroke.Methods— This clinical trial enrolled 522 patients with acute ischemic stroke in the middle cerebral artery territory (intent-to-treat population) with 460 patients treated as planned (per-protocol population). Within 6 hours of symptom onset, at 24 and 48 hours, EPO was infused intravenously (40 000 IU each). Systemic thrombolysis with recombinant tissue plasminogen activator was allowed and stratified for.Results— Unexpectedly, a very high number of patients received recombinant tissue plasminogen activator (63.4%). On analysis of total intent-to-treat and per-protocol populations, neither primary outcome Barthel Index on Day 90 (P=0.45) nor any of the other outcome parameters showed favorable effects of EPO. There was an overall death rate of 16.4% (n=42 of 256) in the EPO and 9.0% (n=24 of 266) in the placebo group (OR, 1.98; 95% CI, 1.16 to 3.38; P=0.01) without any particular mechanism of death unexpected after stroke.Conclusions— Based on analysis of total intent-to-treat and per-protocol populations only, this is a negative trial that also raises safety concerns, particularly in patients receiving systemic thrombolysis."],["dc.identifier.doi","10.1161/STROKEAHA.109.564872"],["dc.identifier.gro","3150483"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7252"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.subject","clinical trial; hematopoietic growth factor; neuroprotection; NIHSS; rtPA"],["dc.title","Recombinant Human Erythropoietin in the Treatment of Acute Ischemic Stroke"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

EPO protects neurons from hypoxic/ ischemic injury. The objective of this trial is to study the safety and efficacy of recombinant human EPO (rhEPO) for treatment of ischemic stroke in man. Materials and Methods: The trial consisted of a safety part and an efficacy part. in the safety study, 13 patients received rhEPO intravenously (3.3 x 10(4) IU/50 m/130 min) once daily for the first 3 days after stroke. in the double-blind randomized proof-of-concept trial, 40 patients received either rhEPO or saline. Inclusion criteria were age {.extbackslash}textless80 years, ischemic stroke within the middle cerebral artery territory confirmed by diffusion-weighted MRI, symptom onset {.extbackslash}textless8 hr before drug administration, and deficits on stroke scales. The study endpoints were functional outcome at day 30 (Barthel index, modified Rankin scale), NIH and Scandinavian stroke scales, evolution of infarct size (sequential MRI evaluation using diffusion-weighted [DWI] and fluid-attenuated inversion recovery sequences [FLAIR]) and the damage marker S100ss. Results: No safety concerns were identified. Cerebrospinal fluid EPO increased to 60-100 times that of nontreated patients, proving that intravenously administered rhEPO reaches the brain. in the efficacy trial, patients received rhEPO within 5 hr of onset of symptoms (median, range 2:40-7:55). Admission neurologic scores and serum S100beta concentrations were strong predictors of outcome. Analysis of covariance controlled for these two variables indicated that rhEPO treatment was associated with an improvement in follow-up and outcome scales. A strong trend for reduction in infarct size in rhEPO patients as compared to controls was observed by MRI. Conclusion: intravenous high-dose rhEPO is well tolerated in acute ischemic stroke and associated with an improvement in clinical outcome at 1 month. A larger scale clinical trial is warranted."],["dc.identifier.gro","3150429"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7192"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","1076-1551"],["dc.relation.orgunit","Institut für Allgemeinmedizin"],["dc.title","Erythropoietin therapy for acute stroke is both safe and beneficial"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]
