Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of MDCO-2010 in Patients Undergoing Elective Coronary Artery Bypass Graft Surgery

• Status: Completed
• Trial end date: 2011-06-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to demonstrate that periprocedural infusion of escalating doses of MDCO-2010 is safe and tolerated in patients undergoing elective CABG surgery, to characterize the single dose pharmacokinetics of MDCO-2010, to investigate the effect of MDCO-2010 on pharmacodynamics (biomarkers of fibrinolysis and coagulation parameters), and to investigate the effect on exploratory clinical endpoints of bleeding, transfusion requirements and reexploration.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No
