E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
PK Module: To evaluate the PK of CSL689 (0.75 and 1.5 mg/kg) in subjects with hemophilia (A or B) and inhibitors and to compare the PK of 1.5 mg/kg CSL689 with the labeled doses of NovoSeven rFVIIa (0.09 and 0.27 mg/kg). Dose-evaluation Module: To determine the best dose (population-based best dose) of the 2 CSL689 doses evaluated (0.75 and 1.5 mg/kg). Repeated-dose Module: To evaluate the clinical efficacy of the population-based best dose of CSL689 for on-demand therapy of bleeding events in subjects with hemophilia (A or B) and inhibitors. |
Modulo PK: valutare PK di CSL689 (0,75 e 1,5 mg/kg) in soggetti con emofilia (A o B) e produzione di inibitori e confrontare PK di CSL689 alla dose di 1,5 mg/kg con le dosi approvate di NovoSeven rFVIIa (0,09 e 0,27 mg/kg). Modulo di valutazione della dose: determinare la dose migliore (migliore dose basata sulla popolazione) tra le 2 dosi di CSL689 valutate (0,75 e 1,5 mg/kg). Modulo a dose ripetuta: valutare l¿efficacia clinica della migliore dose basata sulla popolazione di CSL689 per la terapia al bisogno di episodi emorragici in soggetti con emofilia (A o B) e produzione di inibitori. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the safety and tolerability of intravenous (IV) administration of CSL689 |
Valutare la sicurezza e la tollerabilit¿ della somministrazione endovenosa (EV) di CSL689. |

E.5 End points |
E.5.1 | Primary end point(s) |
PK of CSL689 and NovoSeven rFVIIa will be assessed based on plasma FVIIa activity with and without baseline correction.
