Filter by:The main aim of the study is to evaluate the effectiveness of prophylaxis with recombinant von Willebrand factor (rVWF) in children. This study will enroll those participants who have been previously treated with VWF product or with a plasma-derived VWF (pdVWF) product. In this study, participants will be treated with rVWF for 12 months. During the study, participants will visit the study clinic 6 times after treatment initiation.
Von Willebrand Disease (VWD) is the most common inherited bleeding disorder affecting up to 0.1% of the population, is usually characterized by mucocutaneous bleeding, HMB, surgical bleeding or other hemostatic challenges. Severe bleeding events require VWF concentrates administered solely through intravenous access. Emicizumab (Hemlibra) is a monoclonal bispecific antibody developed to bind activated FIX and FX and mimic FVIII cofactor functionality. Hemlibra is administered via subcutaneous injection rather than intravenous infusion. The hypothesis of this study is that Emicizumab is safe and efficacious for prophylaxis in severe VWD and concomitant VWD/hemophilia patients.
A web-based registry will be created by the sponsor, VWD Connect Foundation (VCF), to collect data on patients with severe Von Willebrand Disease (sVWD). Data will be self-reported by patients and/or collected by registry personnel, as appropriate. The purpose of the sVWD Patient Registry is to create a database of well-characterized (with respect to demographics, medical history, symptoms, laboratory and genetic data, etc.) patients with sVWD for participation in retrospective and prospective research.
The main aim of this study is to estimate the risks of certain adverse events in adults with Von Willebrand Disease treated with VEYVONDI. No study medicines will be provided to participants in this study. Data from medical records of participants diagnosed with Von Willebrand Disease and treated with VEYVONDI will be evaluated during this study.
The working hypothesis is that patients with Von Willebrand Disease-type 2B may have neurological symptoms due to the chronic formation of platelets/Von Willebrand Factor aggregates. Interestingly, several patients present nonspecific neurological symptoms (nystagmus, headaches, memory disorder, …) which may be associated with cerebral microangiopathy and chronic microvessel inflammation secondary to Von Willebrand Disease-type 2B due to chronic exposure to Von Willebrand Factor-platelets complexes.
The WIL-33 study aims to determine the efficacy, pharmacokinetics, immunogenicity and safety of wilate as routine prophylaxis in up to 12 paediatric patients (eight evaluable) with severe von Willebrand Disease VWD (defined as screening von Willebrand factor ristocetin cofactor activity [VWF:RCo] <20%) under the age of 6 years, over a period of 12 months.
The objective of this observational study HOPSCOTcH-WILL II is to provide an accurate and detailed account of current Von Willebrand Disease (VWD) therapeutic management by collecting real-life data on hemorrhagic treated events in the 5 Western French Hemophilia Treatment Center. The HOPSCOTCH-WILL II study aims to describe therapeutic management of patients with VWD, following the provision of a recombinant drug in France; It will also permit to carry out a budget impact analysis to quantify the economic significance of this new era.
Von Willebrand's disease (VWD) is the most common inherited bleeding disorder. It arises from a deficiency in the quality or quantity of von Willebrand factor (VWF), a multimeric protein that is required for platelet adhesion. Typical patients present with mucocutaneous bleeding symptoms because of reduced circulating von Willebrand factor (VWF) In this study we will use the ISTH/SSC BLEEDING assessment tool as a standardized questionnaire and a proposal for a new bleeding score for inherited bleeding disorders
The study aims to study the expression of numerous proteins involved in angiogenesis in 70 patients with von Willebrand disease in order to try to identify markers of interest. Secondly, the investigators plan to investigate whether there is a relationship between the proteins tested, the distribution of multimers and the clinical phenotype of the patients, in particular by looking for the presence of bleeding linked to the presence of angiodysplasias.
Primary Objective: -To characterize the pharmacokinetics (PK) of BIVV001 after a single intravenous (IV) administration, as assessed by factor VIII (FVIII) activity determined by the one-stage activated partial thromboplastin time (aPPT) clotting assay, as well as, BIVV001 capture chromogenic Coatest FVIII activity assay Secondary Objective: -To assess the safety and tolerability of a single IV dose of BIVV001 in adult patients with type 2N and 3 VWD
