Filter by:Retrospective, multicenter study in patients with hemophilia B. This study will be placed at 20 to 50 hemophilia treatment centers in North America and the EU, and is designed to estimate the frequency of Class II and III allergic reactions in association with the administration of any FIX concentrate. Following informed consent and eligibility, historical patient information including demographics, allergy history, hemophilia history, frequency and severity of allergic reaction(s), number of exposure days with products causing allergic reactions, exposure days to blood products including FIX concentrates, treatment for allergic reaction(s), outcome of event(s), any other adverse event(s) occuring within 48 hours of onset of allergic reaction(s), rechallenge and outcome, switch to another FIX product (if applicable) and outcome, current status of patient, and results of any special studies (eg, skin or RAST testing, alloantibody analyses, ect) will be collected.
This is an open-label multi-center Registry in patients with hemophilia B receiving BeneFIX. All patients who begin treatment with BeneFIX in European Union countries, will be eligible for participation. Patient demographics will be collected at baseline for all patients. A baseline FIX activity and Bethesda assay for inhibitor based on historical data should be recorded if available. Adverse events as defined in the protocol will also be reported on the appropriate forms. Data will be collected from patients on an ongoing basis to ensure that information is being captured for each patient being treated with BeneFIX.
In this postmarketing study, the safety of Nonafact® (human coagulation factor IX) is evaluated in previous treated and untreated patients with severe, moderate or mild haemophilia B.
This trial is conducted in the United States of America (USA). This study compares the effectiveness and safety of NovoSeven® to FEIBA (FEIBA VH) in haemophilia patients with inhibitors being treated for joint bleeds.
This trial is conducted in Africa, Asia, Europe, South America, and the United States of America (USA). The purpose of this study is to evaluate the effectiveness of secondary prophylactic treatment with NovoSeven® in haemophilia A and B patients with inhibitors.
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.
The primary objective of this clinical research study is to assess the safety and efficacy of rFIX for a minimum of 6 months in previously treated patients (PTPs) with hemophilia B (FIX:C ≤2%) during standard-of-care treatment (on-demand, prophylaxis, and through major and minor surgical procedures).
In this study a modified virus called adeno-associated virus (AAV) will be used to transfer a normal gene for human clotting factor IX into patients with severe hemophilia B (AAV human Factor IX vector). Gene therapy is a very new medical technique being used in a number of clinical studies for diseases such as cancer and cystic fibrosis. At this time, the U.S. Food and Drug Administration has approved no gene transfer products for commercial use. To date, 8 subjects have received AAV vector in the muscle for a hemophilia B trial by intramuscular injection, and, to date, 6 subjects have been treated with AAV vector in the current hemophilia B liver trial. Eleven cystic fibrosis subjects have received AAV vector into their nasal sinuses or lungs to date. In this study, AAV human Factor IX vector will be injected into the liver using a catheter inserted into a large blood vessel (called the proper hepatic artery or the right hepatic artery).
To characterize the safety and efficacy of rFIX in children less than 6 years of age with severe hemophilia B in the setting of acute bleeding episodes, prophylaxis, and/or surgery. 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.
OBJECTIVES: Assess the safety and long-term efficacy of monoclonal factor IX concentrate in patients with factor IX deficiency.
