Filter by:Research project for validation of a questionnaire on compliance to treatment in patients with hemophilia. It is intended to validate the American VERITAS-PRO scale according to the international methodology validation questionnaires: reverse translation, according to intersubject patients, psychometric validation and reliability analysis with large sample of patients.
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.
Research project whose main objective is to evaluate the use of a technology platform (uPatient) to register the prophylactic treatment of patients with hemophilia treated in different Hematology and Hemotherapy services of several hospitals in Spain.
This study is being conducted by BioMarin Pharmaceutical Inc. as an open label, dose escalation study in order to determine the safety and efficacy of valoctocogene roxaparvovec (an Adenovirus-Associated Virus based gene therapy vector in participants with severe haemophilia A.
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
Using whole blood samples and plasma samples obtained from some hemophilia A patients with inhibitors, the investigators will perform the coagulation assessment in the co-presence of aPCC and factor VIII by comprehensive coagulation assays and flow chamber analysis under blood flow conditions.
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.
