Active clinical trials for "Hemophilia A"

This study aims to investigate prospectively throughout a period of 3- 6 months and not to exceed 12 months (according to local therapeutic plans) patients experiences of treatment with Factor VIII in the new device named FuseNGO, a new delivery system for Factor VIII compared to their previous delivery system.

Abnormalities in the gene encoding Factor VIII (FVIII) results in hemophilia A, an X-linked recessive bleeding disorder with a prevalence of 1 in 5000 males. Hemophilia A patients are classified into 3 different categories based on residual FVIII activity compared to normal: mild (6-40%), moderate (1-5%) and severe (<1%). This categorization correlates to some degree with bleeding phenotype, but does not completely define it. Some patients with hemophilia A bleed less often than others despite identical plasma FVIII levels. The cause(s) of this phenotype heterogeneity in hemophilia A remains largely unknown, despite a number of studies of possible factors. Activated platelets, in addition to their role in primary hemostasis, play a major role in secondary hemostasis (coagulation) by providing a phospholipid surface to which coagulation factors bind. A role for platelets in the hemorrhagic propensity of hemophilia A has been suggested in the past, but only a small number of studies have been performed with limitations in assays performed and numbers of patients. The purpose of the present study is to determine whether platelet reactivity in severe hemophilia A patients is associated with past bleeding frequency and/or predicts future bleeding frequency.

This study is conducted in Europe, and North and South America. The aim of this study is to provide additional documentation of the immunogenicity, and obtain additional clinical data, of turoctocog alfa in the setting of normal clinical practise in patients previously treated with a factor VIII agent (FVIII).

The aim of this international prospective post-marketing surveillance study is to obtain data on treatment procedures, long-term safety and efficacy and patient acceptance of KOGENATE Bayer/FS in treatment of patients with haemophilia A under daily-life treatment conditions.

This study is conducted in Europe and North and South America. The primary aim of this observational study is to evaluate the frequency and pattern of bleeding episodes in haemophilia patients receiving preventative treatment with activated recombinant human factor VII. The secondary aim is to evaluate which patients are selected for this treatment, the dose and dose intervals used, and the safety of activated recombinant human factor VII when used as prevention. The study also aims to increase understanding of the unmet medical need and clinical relevance of preventative treatment in haemophilia patients.

The aim of this international prospective, non-interventional post-marketing surveillance study is to obtain data on treatment procedures, long-term safety and efficacy and patient acceptance of KOGENATE Bayer in treatment of patients with haemophilia A under daily-life treatment conditions.

This study is conducted in the United States of America (USA). The aim of this study is to investigate the at-home-administration of bypassing agents for treatment of bleeding episodes in patients with congenital haemophilia with inhibitors to factors VIII and IX. We are further investigating how bleeding episodes affect the quality of life of the patient and their family or caregivers.

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.

To examine mechanisms of individual differences in the progression of HIV infection in hemophiliacs.

This study is a multicenter phase III uncontrolled open-label trial to evaluate the efficacy,safety and pharmacokinetics of SCT800 in regular prophylaxis and perioperative treatment in patients (<12 years old) with severe hemophilia A who have been previously treated with coagulation factor VIII(FVIII) . This study includes two phases: the screening period and prophylaxis period.Prophylaxis with 25 - 50 IU/kg of SCT800 shall be administered once every other day or three times per week starting from Visit 1 and prophylaxis with SCT800 shall continue for 24 consecutive weeks.
