Study Summary

The primary objective of this study was to assess the efficacy and safety of 2 dose levels of ecallantide versus placebo in reducing blood loss following cardiopulmonary bypass (CPB), as measured by chest tube drainage during the first 12 hours postoperatively or until the chest tube was removed, whichever came first, in patients undergoing primary coronary artery bypass grafting (CABG), single valve repair, or single valve replacement. The secondary objective was to compare the efficacy of all ecallantide-treated participants (pooled high and low-doses) to placebo and to compare the high-dose to the low-dose ecallantide group. Other secondary objectives were to evaluate pharmacokinetics and antibody formation.

Primary Outcome

Mean volume of chest tube drainage during the first 12 hours postoperatively or until chest tube removal, whichever occurred first, is presented for each treatment group.
