Primary Outcome Measures:
  • The primary variable will be the clinical response of BeneFix* in avoiding stopping or avoiding bleeding. [ Time Frame: 9 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The secondary variables will be hemostasis and blood loss during and after surgery. [ Time Frame: 9 months ] [ Designated as safety issue: No ]

Enrollment: 14
Study Start Date: December 2001
Study Completion Date: July 2004
Arms Assigned Interventions
Experimental: 1
Patients will receive Benefix IV according to blood amount
Drug: Recombinant Factor IX Coagulation
Benefix IV each 12 hours for 2 a 5 days

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.
