BeneFIX® , Coagulation Factor IX (Recombinant), is a purified protein produced by recombinant DNA technology for use in therapy of factor IX deficiency, known as hemophilia B or Christmas disease. Coagulation Factor IX (Recombinant) is a glycoprotein with an approximate molecular mass of 55,000 Da consisting of 415 amino acids in a single chain. It has a primary amino acid sequence that is identical to the Ala148 allelic form of plasma-derived factor IX, and has structural and functional characteristics similar to those of endogenous factor IX.
BeneFIX® , Coagulation Factor IX (Recombinant), is indicated for the control and prevention of hemorrhagic episodes in patients with hemophilia B (congenital factor IX deficiency or Christmas disease), including control and prevention of bleeding in surgical settings.
BeneFIX® , Coagulation Factor IX (Recombinant), is not indicated for the treatment of other factor deficiencies (e.g., factors II, VII, VIII, and X), nor for the treatment of hemophilia A patients with inhibitors to factor VIII, nor for the reversal of coumarin-induced anticoagulation, nor for the treatment of bleeding due to low levels of liver-dependent coagulation factors.

A randomized, partially blinded, multicenter, active-controlled, dose-ranging study assessing the safety, efficacy, and pharmacodynamics of the REG1 anticoagulation system in patients with acute coronary syndromes: design and rationale of the RADAR Phase IIb trial. [2011.02]
Anticoagulants are the cornerstone of current acute coronary syndrome (ACS) therapy; however, anticoagulation regimens that aggressively reduce ischemic events are almost uniformly associated with more bleeding... The objectives of RADAR are (1) to determine the safety of a range of levels of RB006 reversal with RB007 after catheterization, (2) to confirm whether a dose of 1 mg/kg RB006 results in near-complete inhibition of factor IXa in patients with ACS, and (3) to assess the efficacy of RB006 as an anticoagulant in patients with ACS undergoing percutaneous coronary intervention.
First clinical application of an actively reversible direct factor IXa inhibitor as an anticoagulation strategy in patients undergoing percutaneous coronary intervention. [2010.08.10]
CONCLUSIONS: This study demonstrates the clinical translation of a novel platform of anticoagulation targeting factor IXa and its active reversal to percutaneous coronary intervention and provides the basis for further investigation. CLINICAL TRIAL REGISTRATION:URL: http://www.clinicaltrials.gov. Unique identifier: NCT00715455.
Coagulation factors II, V, IX, X, XI, and XII, plasminogen, and alpha-2 antiplasmin and risk of coronary heart disease. [2010.04.30]
AIM: To examine whether plasma levels of coagulation factors II, V, IX, X, XI, and XII, plasminogen, and alpha-2 antiplasmin are associated with coronary heart disease (CHD) in a prospective case-cohort study... CONCLUSIONS: Positive associations of factors IX and XI, and alpha-2 antiplasmin with incident CHD were not strong and accounted for by classical coronary risk factors.
Coagulation factors IX through XIII and the risk of future venous thrombosis: the Longitudinal Investigation of Thromboembolism Etiology. [2009.10.01]
Higher levels of procoagulant factors and factor XII deficiency may be risk factors for first venous thromboembolism (VTE). We studied associations of coagulation factors IX through XIII with risk of future VTE in 2 general population samples... Among these procoagulant factors, only elevated factor XI was a risk factor for VTE.
Effects of second and third generation oral contraceptives and their respective progestagens on the coagulation system in the absence or presence of the factor V Leiden mutation. [2002.02]
Compared to second generation, the use of third generation oral contraceptives has been associated with an increased risk of venous thrombosis especially in women with the factor V Leiden mutation. To find an explanation for these risk differences we investigated the effects of desogestrel- and levonorgestrel-containing oral contraceptives as well as their progestagens separately on the coagulation system in the absence or presence of the factor V Leiden mutation...

Pivotal Study (Pharmacokinetics, Efficacy, Safety) of BAX 326 (rFIX) in Hemophilia B Patients [Completed]
The purpose of this pivotal Phase 1/3 study is to determine the pharmacokinetic (PK)
parameters, the hemostatic efficacy, and the safety of BAX 326, a recombinant factor IX, in
previously treated patients (PTPs) with severe and moderately severe hemophilia B.
Post Marketing Observational Study of Reformulated BeneFIX [Completed]
The primary objective of this observational study is to collect safety data on reformulated
BeneFIX as prescribed in routine clinical practice conditions in France. The secondary
objectives are to collect data on the clinical course of individuals treated with
reformulated BeneFIX and on the ease of reformulated BeneFIX.
