Active clinical trials for "Hemophilia A"

The purpose of the study is to evaluate the effect of prophylactic treatment on the number of joint bleeds and quality of life in severe hemophilia A subjects compared to on-demand treatment in a one-group two-treatment schedule design. In addition, the effect of prophylactic treatment on the joint function, the number of all bleeds, and on the quality of life compared to on-demand treatment and health-economic data will be assessed.

Hemophilia A is a serious blood clotting disorder caused by a lack of factor VIII, a specialized protein needed for normal blood clotting to occur. Individuals with this disease may experience spontaneous bleeding, pain and swelling in their joints due to excess bleeding, and bruising. A common treatment for severe hemophilia A is to intravenously replace the deficient blood clotting factor; however, some individuals may develop antibodies to this replacement factor. This study will evaluate the effectiveness of rituximab at reducing the antibodies that develop in response to the replacement factor in individuals with severe hemophilia A.

This study will examine the efficacy and safety of ReFacto AF in patients with severe and moderately severe hemophilia A undergoing elective major surgery when administered by either bolus injections (BI) or continuous infusion (CI).

The purpose of this study is to evaluate whether Antihemophilic factor, recombinant, manufactured protein-free (rAHF-PFM) is effective and safe in the treatment of hemophilia A patients who have not been treated with factor VIII (FVIII) before.

Primary Objective: To characterize the frequency of bleeding episodes (BE) while receiving fitusiran treatment, relative to the frequency of bleeding episodes while receiving factor concentrate or bypassing agent (BPA) prophylaxis. Secondary Objectives: To characterize the following while receiving fitusiran treatment, relative to receiving factor or BPA prophylaxis: the frequency of spontaneous bleeding episodes the frequency of joint bleeding episodes health related quality of life (HRQOL) in participants greater than or equal to (>=) 17 years of age To characterize the frequency of bleeding episodes during the onset and treatment periods in participants receiving fitusiran. To characterize the safety and tolerability of fitusiran. To characterize the annualized weight-adjusted consumption of factor/BPA while receiving fitusiran treatment, relative to receiving factor or BPA prophylaxis.

The goal of this observational study is to learn about the changes in coagulation factor VIII and IX levels in patients undergoing liver transplantation to help guide future management of coagulation factor replacement in patients with hemophilia and liver disease. The question we aim to answer is: should the recommendations for factor replacement in patients with hereditary bleeding disorders be altered in the setting of end stage liver cirrhosis? Participants will be asked to provide two blood samples, one at the beginning of their liver transplant, and one after their liver transplant.

This observational study will obtain liver biopsy samples and evaluate the long-term effect of adeno-associated virus (AAV)-mediated gene therapy on the liver tissue in adult patients with hemophilia A or hemophilia B who have previously been treated with a factor VIII or factor IX gene-containing AAV-vector for liver-targeted gene transfer. Participants are from a cohort of patients treated with AAV-mediated gene transfer and at least 6 months after vector infusion

The goal of this study is to give gather more information on how safe and well Jivi works in patients with severe hemophilia A. Jivi has been approved by various regulatory agencies, including the FDA, Health Canada, Japanese Health Authority and the European Medicinal Agency. 25 patients will be enrolled and will stay for 1 to 2 years in this study depending on their treatment frequency. Researcher will monitor during the course of the study whether patients are developing antibodies (a protein made by the body in response to the drug) affecting the effectiveness of Jivi. In addition information on bleedings and patient's wellbeing will be collected.

Phase 2b, single-center, open-label study designed to evaluate the pharmacokinetics, pharmacodynamics, efficacy and safety of subcutaneous (SC) prophylaxis treatment regimens with CB2679d in 6 adult, male subjects with severe congenital hemophilia B.

Phase 3/4, single arm, open-label study to evaluate PK, safety, and efficacy of APVO101 prophylaxis in severe or moderately severe hemophilia B subjects < 12 years of age.
