E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Part A: • To investigate the safety, tolerability and dose-effect-relationship of 3 different doses of ularitide on renal and central hemodynamics and on renal excretory function in patients post cardiac surgery, who have developed AKI (as defined in this protocol), and to identify the individual maximum tolerated dose of ularitide in these patients. Part B: • To investigate the safety, tolerability, and effect of the individual maximum tolerated ularitide dose identified in Part A for up to an additional 42 hours. |
