Active clinical trials for "Hemophilia B"

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.

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.

Hemophilia A and B are congenital, recessive X-linked disorders caused by lack or deficiency of clotting factor VIII (FVIII) or IX (FIX), respectively. The severity of the disease depends on the reduction of levels of FVIII or FIX, which are determined by the type of the causative mutation in the genes encoding the factors (F8 and F9, respectively). The hallmark clinical characteristic, especially in untreated severe forms, is bleeding (spontaneous or after trauma) into major joints such as ankles, knees and elbows, which can result in the development of arthropathy. Intracranial bleeds and bleeds into internal organs may be life-threatening. The median life expectancy was ~30 years until the 1960s, but improved understanding of the disorder and development of efficacious therapy based on prophylactic replacement of the missing factor has caused a paradigm shift, and today individuals with hemophilia can look forward to a virtually normal life expectancy and quality of life.

This study is focused on males who have Hemophilia B and who need regular preventive treatment with factor IX protein (FIX) replacement therapy to prevent and also to control their bleeding events. The aim of the study is to gather at least 6 months of information on bleeding events for each individual participant while they continue to use their usual FIX replacement therapy. There is no experimental treatment being tested in this study. The study is informational, and part of a larger program to understand and treat Hemophilia B with a potential experimental new therapy in the future. After you complete this research study, should you be interested and eligible, you may be offered the opportunity to take part in a future study with this new therapy. There is no obligation to agree to taking part in this future study. The study is looking to answer several other research questions to help understand each participant's individual disease characteristics, including: How often you use FIX replacement therapy, both on a regular basis (prophylaxis) and as needed to treat bleeding events Measurement of FIX activity (factor IX is a clotting factor) by different laboratories using different types of tests in Hemophilia B patients Possible complications from the FIX replacement therapy you receive (you will continue to use your usual standard of care FIX prophylaxis for Hemophilia B during the study) How your quality of life is affected by Hemophilia B How your joint health is affected by Hemophilia B How often you visit the emergency room, urgent care center, physician's office, hospital, or have a telemedicine visit as a result of bleeding events Whether the body makes antibodies (a protein produced by the body's immune system) against the FIX replacement therapy you receive, which could make the drug less effective or could lead to side effects

This trial is conducted in Europe. The aim of the trial is to investigate the pharmacokinetics (the exposure of the trial drug in the body) and pharmacodynamics (the effect of the investigated drug on the body) of rFVIIa (activated coagulation factor VII) following one single injection of 270 microg/kg compared to three injections of 90 microg/kg rFVIIa in patients with haemophilia.

The purpose of this study will be to determine if a once-weekly prophylaxis regimen of BeneFIX in subjects with moderately severe to severe Hemophilia B is safe and effective.

This study will examine the safety and efficacy of a Recombinant Coagulation Factor IX Albumin Fusion Protein (rIX-FP) for the control and prevention of bleeding episodes in subjects who have previously received factor replacement therapy for hemophilia B. The study consists of a screening period, a pharmacokinetic (PK) period, followed by approximately a 5 month treatment period. Subjects will receive weekly routine prophylactic therapy and on-demand treatment for bleeding episodes. In addition, subjects who are not on routine factor replacement therapy prior to the study will receive only on-demand treatment for bleeding episodes.

To compare the first and second recovery assessments on Replenine®-VF and to evaluate recovery of different batches if patients changed batches during the study. To evaluate Replenine®-VF in terms of long-term clinical efficacy, tolerance and safety

The purpose of the study is to assess the hemostatic efficacy and safety of BAX 326 in subjects with severe (FIX level < 1%) or moderately severe (FIX level 1-2%) hemophilia B undergoing major or minor elective or emergency surgical, dental or other invasive procedures.

This trial is conducted in Europe. The aim of this trial is to determine the pharmacokinetics of activated recombinant human factor VII (NovoSeven®) in haemophiliac patients in a non-bleeding state.
