Brief summary: The primary objective of this study is to prospectively document the exposure to IMMUNINE and to monitor FIX inhibitors over a period of approximately 20 to 50 exposure days while receiving prophylactic treatment in up to 50 previously treated patients (PTPs) aged 12-64 years and approximately 20 pediatric PTPs up to 11 years of age with severe (FIX level \< 1%) or moderately severe (FIX level \<= 2%) hemophilia B who are planned to enter BAX326 study 250901, provided all eligibility criteria are met.

In addition, this study will evaluate the efficacy, safety, immunogenicity, thrombogenicity, and health-related quality of life (HR QoL) of these subjects.


Eligibility criteria: Inclusion Criteria:

* Subject is up to 64 years old at the time of screening
* Subject and/or legal representative has/have provided signed informed consent
* Subject has severe (FIX level \< 1%) or moderately severe (FIX level \<= 2%) hemophilia B (based on the one stage activated partial thromboplastin time (aPTT) assay), as tested at screening at the central laboratory
* Subject is previously treated with plasma-derived or recombinant FIX concentrate(s), cryoprecipitate or fresh frozen plasma (FFP) for approximately 100-150 exposure days (EDs) if \>= 6 years old, or 20-50 EDs if \< 6 years old, and is planned to enter BAX326 study 250901. The number of EDs are derived from the subject's treatment regimen and his/her bleeding pattern
* Subject is willing to receive prophylactic treatment for the duration of the study
* Subject is immunocompetent as evidenced by a CD4 count \>= 200 cells/mm(3)
* Subject is human immunodeficiency (HIV) negative or is HIV+ with a viral load \< 200 particles/μL \~ \< 400,000 copies/mL
* Female subject of childbearing potential, presents with a negative serum pregnancy test, and agrees to employ adequate birth control measures for the duration of the study
* Subject is willing and able to comply with the requirements of the protocol

Exclusion Criteria:

* The subject has a detectable factor IX inhibitor at screening, with a titer \>= 0.6 Bethesda Units (BU) as determined by the Nijmegen modification of the Bethesda assay in the central laboratory
* The subject has a history of factor IX inhibitors with a titer \>= 0.6 BU (as determined by the Nijmegen modification of the Bethesda assay or the assay employed in the respective local laboratory) at any time prior to screening
* The subject has a history of allergic reaction, eg, anaphylaxis, following exposure to factor IX concentrate(s)
* The subject has a known hypersensitivity to hamster proteins
* The subject has evidence of a thrombotic disease, fibrinolysis or disseminated intravascular coagulation (DIC)
* The subject is scheduled for elective surgery, unless the surgery is medically required within the anticipated study period
* The subject has an abnormal renal function (serum creatinine \> 1.5 times the upper limit of normal)
* The subject has severe chronic liver disease as evidenced by, but not limited to, any of the following: International Normalized Ratio (INR) exceeding the upper limit of normal (ULN), hypoalbuminemia, portal vein hypertension including presence of otherwise unexplained splenomegaly and history of esophageal varices
* The subject has active hepatic disease with alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels \>= 5 times the upper limit of normal. During the study, subjects with chronic hepatitis B or C may have fluctuations of up to 5 times the upper limit of normal but will not require discontinuation.
* The subject has been diagnosed with an inherited or acquired hemostatic defect other than hemophilia B
* The subject's platelet count is \< 100,000/mL
* The subject has a clinically significant medical, psychiatric, or cognitive illness, or recreational drug/alcohol use that, in the opinion of the investigator, would affect subject's safety or compliance
* The subject is currently receiving, or is scheduled to receive during the course of the study, an immunomodulating drug other than anti-retroviral chemotherapy (eg, α-interferon, corticosteroid agents at a dose equivalent to hydrocortisone greater than 10 mg/day)
* The subject is unwilling to consider further participation in BAX 326 (rFIX) pivotal study 250901 or BAX 326 pediatric study
* The subject has participated in another investigational study within 30 days of enrollment or is scheduled to participate in another clinical study involving an investigational product (IP) or investigational device during the course of this study
* The subject is a member of the team conducting this study or is in a dependent relationship with one of the study team members. Dependent relationships include close relatives (ie, children, partner/spouse, siblings, parents) as well as employees of the investigator or site personnel conducting the study.
