Safety, Tolerability and Pharmacodynamics of AP214 Acetate in Patients Undergoing Cardiac Surgery
2009年5月29日 更新者：Action Pharma A/S
The purpose of the present research study is to investigate for the first time, the safety and tolerability of infusion doses of AP214 in subjects having heart surgery such as coronary bypass graft and/or valve repair or replacement surgery.
AP214, the investigational drug, is being developed to potentially prevent post-surgical kidney injury after thoracic aortic aneurysm repair.
