Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of MDCO-2010 in Patients Undergoing Elective Coronary Artery Bypass Graft Surgery
A Double-blind, Placebo-controlled, Randomized, Single Ascending Dose Study of the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of MDCO-2010 in Patients Undergoing Elective CABG Surgery
調査の概要
詳細な説明
This protocol describes a study of the investigational drug MDCO-2010 as a haemostasis modulator in patients undergoing elective Coronary Artery Bypass Graft (CABG) surgery involving a cardiopulmonary bypass (CPB).
Perioperative bleeding is a serious complication that adversely affects the morbidity and mortality of cardiac surgery. To alleviate this complication, prophylactic antifibrinolytic therapies are now widely accepted as a strategy to inhibit excessive fibrinolysis.
MDCO-2010, a synthetic small molecule, is a direct inhibitor of plasmin and plasma kallikrein. Both of these have been implicated with impaired haemostasis. In addition, potent inhibition of coagulation factors Xa, XIa and activated Protein C has been demonstrated. Thus, MDCO-2010 has the potential to mitigate excessive fibrinolysis and thrombin generation during cardiac surgery involving a cardiopulmonary bypass. In particular the latter is supposed to provide additional benefits beyond reducing transfusion requirements.
