Filter by:The overall objective is to enroll patients with acquired hemophilia A (AHA) who are prescribed and treated with Obizur, to assess safety, and to describe factors related to safety, utilization and effectiveness in a real-world setting.
Severe hemophilia is characterized by frequent and lifelong bleeding, with more than 60% of bleeds occurring into joints . Repeated joint bleeding leads to chronic synovitis, cartilage damage and bony destruction. Currently available treatment of hemophilic arthropathy, such as analgesics, NSAIDs, and hyaluronic acid (HA), are predominantly directed toward the symptomatic relief of pain and inflammation, but they do little to reduce joint cartilage degeneration. Platelet-Rich Plasma (PRP) is a simple and minimally invasive method that provides a natural concentrate of autologous growth factors from the blood. This method is now being increasingly applied in clinical practice to treat musculoskeletal disorders, such as tendon repairment and osteoarthritis. To the best of our knowledge, no study applies PRP for arthropathy of knee joint in hemophilia patients. The aim of the study is to investigate the efficacy, safety and duration of benefit of single PRP injection versus five weekly intra-articular injections of HA in patients with hemophilic arthropathy of knee.
1. To compare the efficacy and safety of pharmacokinetic (PK)-guided treatment with BAX 855 targeting FVIII trough levels of 1-3% and approximately 10% (8-12%) 2. To further characterize pharmacokinetic (PK) and pharmacodynamic (PD) parameters of BAX 855
The MOrPH study is designed to identify optimal prophylaxis schedules for children with haemophilia. This involves development of combined pharmacokinetic and pharmacodynamic models. Interpretation of model outputs will be informed by two surveys. The first will survey families of children with haemophilia to ascertain families' values and preferences concerning prophylaxis schedules. The second will survey haemophilia physicians to ascertain the criteria physicians use to prescribe prophylaxis schedules.
Currently dosing for prophylaxis is not individualized, and the general approach is to use a dose of 25-40 units/kg given 3 times per week or every other day. One of the issues with weight-based dosing is the possible over-treatment. This is likely due to the fact that laboratory tests are not sensitive enough at the low levels to support decision-making. The Thromboelastograph (TEG®) and Thromboelastometry (ROTEM®) are coagulation devices, which assess the dynamics of clot formation over time and have several characteristics which suggest they may provide important information for individualized prophylaxis treatment for our patients.
Following the performance of the POTTER observational study, whose primary objective was to collect data on the benefits of secondary prophylaxis versus on demand treatment in terms of prevention of bleeding episodes, the present study aims to extend the observation time up to 10 years, of the same population involved in the previous study. The present study has been designed to allow a focus on long term disease-related damage at joint level in subjects with severe haemophilia A, as well as on the pharmacoeconomics impact of the two different treatment regimens.
Investigate the safety, tolerability and pharmacokinetics of BAY1093884 after Intravenous (IV) and subcutaneous (SC) administration of increasing single doses and SC administration of multiple doses.
This study is conducted in the United States of America (USA). Tha aim of this study is bridging Hemophilia B Experiences, Results and Opportunities into Solutions (B-HERO-S).
Primary Objective: To evaluate the long-term safety and tolerability of fitusiran in male patients with moderate or severe hemophilia A or B Secondary Objectives: - To investigate the long-term efficacy of fitusiran - To characterize the safety and efficacy of concomitantly administered Factor VIII (FVIII), Factor IX (FIX) or bypassing agents (BPA) and fitusiran for treatment of bleeding episodes - To assess changes in health-related quality of life (QOL) over time - To characterize antithrombin (AT) reduction and thrombin generation (TG) increase - To characterize the pharmacokinetics (PK) of fitusiran
The purpose of this study, PerSept 3, is to evaluate LR769 for the prevention of excessive bleeding and achievement of hemostasis in congenital hemophilia A or B patients who have inhibitors to Factor VIII or Factor IX , are aged 6 months to 75 years, inclusive; and who are undergoing elective surgical or other invasive procedures. Administration of LR769 will be performed just prior to surgery/procedure and will be repeated during and after the surgery/procedure to achieve and maintain adequate hemostasis as determined by the investigator's judgment.
