This study will provide an opportunity for systematic observation of treatment with rFIX in children less than 6 years of age regardless of prior FIX treatment. Younger patients exhibit a different pharmacokinetic profile and therefore may respond differently to rFIX infusions when compared with older children and adults. This evaluation will provide data from which recommendations can be made regarding rFIX dosing and treatment of these patients. Surveillance for certain observations that have been made in patients treated with rFIX in the clinical and postmarketing setting will be performed, including inhibitor development, thrombogenicity, FIX recovery/lack of effect, allergic-type manifestations, and RBC agglutination. Comparisons will be derived from published reports and communications describing experience with other FIX products and protein therapeutics in general.

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.
This study will evaluate the safety and efficacy of on-demand treatment with BeneFIX in Chinese hemophilia B subjects
The purpose of this post-approval study is to evaluate the SAFETY AND EFFICACY OF BENEFIX IN SUBJECTS WITH HEMOPHILIA B IN USUAL CARE SETTINGS IN CHINA
Based on the finding that anaphylactic reactions to Benefix ("FIX") are associated with a specific IgE, a Basophil histamine release assay was selected to evaluate and demonstrate subject ...
The primary objective of this clinical research study is to establish the bioequivalence of 2 treatments, rFIX and rFIX-R, when given as a 10-minute intravenous bolus infusion.
Prophylactic injections of factor VIII reduce the incidence of bleeds and slow the development of joint damage in people with hemophilia. The aim of this study was to identify optimal person-specific ...
Although hemophilia B affects 1 in 25,000 males there may be 3 female hemophilia B carriers per affected male. This clinical review highlights the unique challenges faced by hemophilia B carriers incl...
Hemophilia B (HB) is an X-linked bleeding disorder caused by deficiency of factor IX (FIX). Patients with the severe form (FIX
Health-related quality of life (HRQoL) is impaired in patients with hemophilia, however the impact in mild/moderate hemophilia B and affected women is not well characterized.
A phase 1/2 clinical trial of AAV-mediated gene therapy in patients with hemophilia B using an enhanced specific activity factor IX (FIX) transgene reports sustained levels of FIX levels, leading to t...
A deficiency of blood coagulation factor IX inherited as an X-linked disorder. (Also known as Christmas Disease, after the first patient studied in detail, not the holy day.) Historical and clinical features resemble those in classic hemophilia (HEMOPHILIA A), but patients present with fewer symptoms. Severity of bleeding is usually similar in members of a single family. Many patients are asymptomatic until the hemostatic system is stressed by surgery or trauma. Treatment is similar to that for hemophilia A. (From Cecil Textbook of Medicine, 19th ed, p1008)
The classic hemophilia resulting from a deficiency of factor VIII. It is an inherited disorder of blood coagulation characterized by a permanent tendency to hemorrhage.
A hereditary deficiency of blood coagulation factor XI (also known as plasma thromboplastin antecedent or PTA or antihemophilic factor C) resulting in a systemic blood-clotting defect called hemophilia C or Rosenthal's syndrome, that may resemble classical hemophilia.
Bleeding into the joints. It may arise from trauma or spontaneously in patients with hemophilia.
Stable blood coagulation factor involved in the intrinsic pathway. The activated form XIa activates factor IX to IXa. Deficiency of factor XI is often called hemophilia C.
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
