E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoints in this study are frequency and severity of bleeding episodes following prophylactic treatment. Long-term PK data, safety data, and the assessment of hemostatic efficacy (following FXIII concentrate treatment of acute bleeding events and following scheduled surgery where FXIII concentrate was used for prophylaxis prior to the scheduled surgery) are also endpoints in this study. |
