Filter by:The purpose of this study is to use the Medication Adherence Reasons Scale (MAR-Scale) to determine the extent of non-adherence to specific medications indicated to treat cystic fibrosis, hemophilia (A or B), idiopathic pulmonary fibrosis, myasthenia gravis, and sickle cell disease, and to identify the top patient-reported reasons for non-adherence. Internal reliability of the MAR-Scale will also be assessed in each condition.
This study prospectively investigates the safety, FVIII immunogenicity, and hemostatic efficacy of prophylactic HEMLIBRA® given with a concomitant low dose recombinant factor VIII (rFVIII) known as NUWIQ®, in HA infants and children <3 years old who have had little to no previous exposure to FVIII. In addition, the study investigates the safety and efficacy of a novel FVIII ITI regimen in children <21 with existing low and high titer inhibitors (LTI and HTI).
The purpose of this study is to investigate the safety of a test drug to treat hemophilia in adult men.
This pilot study will investigate the use of thromboelastograph (TEG) to determine the primary bypassing agent for the management of bleeding in children and adults severe hemophilia A patients with inhibitors. The study will evaluate the TEG profile for each of the available bypassing agents (FEIBA and rFVIIa) in each participating patient, which will then determine which agent provides the most robust clot formation as measured by the TEG. This study will consist of screening visit and 2-4 pharmacokinetic studies to determine the "best" bypassing agent based on the TEG results. Patients will then be assigned that bypassing agent and dose for the treatment of their bleeding episodes (Prophylaxis or On-demand). Each patient will be then followed for a period of 6 months to monitor short-term safety of those patients whose bypassing agent was modified.
The KAPPa project has the aim to create an international database in which information about clinical features, therapeutic management, burden of illness and costs of severe and moderate haemophilia A patients from different countries and sites is collected. The aim of this project is to analyse the influence of such different characteristics on medical, psychosocial and economic outcomes in patients over the long-term.
Commercial one and two-stage factor VIII assays may not detect some clinically significant inhibitor antibodies. The purpose of the proposed study is to standardize and validate a platelet-based factor VIII activity assay with greater sensitivity to clinically important inhibitory antibodies. Investigators will evaluate the platelet-dependent inhibitory activity vs. conventional inhibitory activity in stored patient plasmas and correlate to bleeding histories
This NIS aims to assess the patient-reported outcomes (PROs) in enrolled subjects
This study will evaluate if Eloctate is superior to Emicizumab in reducing inhibitors in children with severe hemophilia when given before the first bleed (preemptive) and continued weekly to prevent bleeds (prophylaxis); and whether Eloctate immune tolerance induction (ITI) plus emicizumab is superior to Eloctate ITI alone in eradicating inhibitor formation in children and adults with severe hemophilia A.
This trial is conducted in Europe. The aim of the trial is to investigate the bioequivalence of eptacog alfa A 6 mg and NovoSeven® in healthy male subjects.
To evaluate the safety (acute adverse effects associated with infusions, and inhibitor development), pharmacokinetics (PK), and efficacy with respect to breakthrough bleeding and control of hemorrhaging during prophylaxis of IB1001 in subjects with hemophilia B.
