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

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.
Eligibility| Ages Eligible for Study: | 6 Years and older |

| Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Patients with moderate to severe hemophilia B ( < 5% circulating factor IX activity) having acute hemorrhage or requiring "short-term therapy" for intermittent secondary prophylaxis regimens.
