E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate whether postoperative treatment with either of two doses (17.5 or 35 IU/kg LBM) of recombinant factor FXIII (rFXIII) is effective in avoiding any allogeneic transfusions in cardio pulmonary bypass (CPB) surgery subjects with a pre-operative transfusion risk score of 2 or 3 |

To document the safety profile of rFXIII used as replenishment therapy in cardiopulmonary bypass (CPB) surgery.
