Filter by:Elocta (rFVIIIFc) and Alprolix (rFIXFc) are recombinant extended half-life coagulation factor products. The purpose of this non-interventional study is to describe the real-world usage and effectiveness of Elocta and Alprolix in the prophylactic treatment of haemophilia A and B.
The purpose of this study is to seek to understand the patient's perspective around deciding to participate in a clinical trial for a Hemophilia therapy
Rationale: Haemophilia is a rare disease; to improve knowledge international collaboration is needed. Well-defined clinical data will be collected from complete cohorts in order to prevent selection bias. Objective: To collect data on bleeding during neonatal period, endogenous (genetic) and exogenous (treatment-related) determinants of inhibitor development and long term outcome.
A long-term follow-up study to evaluate the safety, tolerability, and efficacy of DTX101 in adult males with moderate/severe to severe hemophilia B.
Severe haemophilia A and B (SHA, SHB) are inherited bleeding disorders affecting male patients and are characterised by low levels of circulating clotting factors VIII and IX respectively. Clinically low levels present with multiple recurrent bleeds into joints and muscle from the first couple of years of life. In addition patients may present with spontaneous and potentially fatal bleeding into any organ. The mainstay of treatment is replacement with the missing factor in the form of intravenous injections of factor VIII and IX. Clotting factors can be given to treat a bleed or can be given to prevent a bleed, and the latter is termed prophylaxis. Regular prophylaxis is the current standard of care and aims to decrease spontaneous bleeding events and resulting joint damage, and this requires patients to self-infuse factor into their veins two to four times week. Patient's compliance with prescribed regimen and recommendations has a significant influence on outcomes. Advances in biomolecular and protein engineering have extended the duration of the effect of clotting factor VIII and IX through multiple mechanisms. This extension of the duration of the effect presents the clinician and patients with opportunities to tailor the treatment to their particular needs, circumstances and body other characteristics. It has been suggested that decreasing the frequency of infusions will improve adherence and thus contribute to improved outcomes. In rare disorders, it is an accepted fact that post-marketing studies are crucial to understand the generalisability of the efficacy and safety outcomes and identify any new safety and efficacy concerns in relation to specific population group. The investigators propose the development of a registry for systematic collection of information with the dual aim of analysing the relationship between patient and treatment characteristics, and outcomes, and simultaneously identify areas for practice development that can improve the overall quality of life experienced by the haemophilia patient community.
The purpose of this survey is to understand the following items observed in the actual clinical use of RIXUBIS. 1. Unexpected adverse drug reactions 2. Occurrence of adverse drug reactions in the actual clinical use 3. Factors that may affect safety and effectiveness 4. Occurrence of Factor IX (FIX) inhibitor development in patients with coagulation FIX deficiency 5. Safety and effectiveness for hemophilia B patients who received routine prophylactic therapy, on-demand therapy and perioperative therapy
Primary: To characterize the safety of RIXUBIS when used under normal clinical care in South Korea. Secondary: To describe hemostatic effectiveness in subjects receiving RIXUBIS under normal clinical care in South Korea.
The German Pediatric Hemophilia Research Database will collect data on the prophylactic and therapeutic use of factor concentrates, complications, outcome measures (joint scores, QoL) and living circumstances in newly diagnosed children with hemophilia.
To evaluate the prevalence of subclinical arthropathy in children with severe hemophilia undergoing a prophylaxis regimen and without evidence of target joints, using a validated ultrasound scoring method.
Recombinant factor VIII Fc (rFVIIIFc) and recombinant factor IX Fc (rFIXFc) are extended half-life coagulation factors approved by Health Canada in 2014 for the treatment of severe hemophilia A and B, respectively. The objectives of this observational study is to describe the change in annual factor consumption, clinical and patient-reported outcomes for patients who switch from recombinant factor VIII (rFVIII) and recombinant factor IX (rFIX) to rFVIIIFc/ rFIXFc in Canada, and to explore clinicians' and patients' reasons for switching or not switching.
