Brief summary

To assess efficacy and safety of BeneFix® for prophylaxis in Short-term therapy and on demand therapy for all bleeding episodes of subjects with hemophilia B.

Detailed description

Phase IV, open-label, non comparative, multicenter, previously treated patients (PTP) clinical trial. Patients with severe or moderate hemophilia B with baseline levels of plasma factor IX \< 5% activity will participate in this study for both treatment regimens: on demand therapy for acute bleeding episodes and therapy for prophylaxis of bleeding episodes ( Short-term therapy)\*. \* Short-Term Therapy: Prophylactic therapy given before surgery, including dental procedures, prior to a event that would likely result in bleeding ( sports, exercise, or heavy work), as well as to prevent further bleeds into a target joint). This short-term therapy for intermittent secondary therapy.
