Von Willebrand disease is an inherited bleeding disorder that impacts the blood's ability to clot properly. Von Willebrand disease is cause by the lack or not working substance in the blood known as Von Willebrand factor.
Current therapy for Von Willebrand disease includes desmopressin acetate (DDAVP) and /or VWF/FVIII concentrates. Patients with severe Von Willebrand disease face a lifetime of weekly treatments and mounting medical bills. Gene therapy could help these patients improve their quality of life by providing the missing factors necessary for the blood's ability to clot properly.
The gene transfer options being studied include naked DNA, viral gene transfer vectors encoding Von Willebrand factor transgenes, and ex vivo cell therapy. The latter involves transplantation of the patient's own cells modified with a corrected copy of the defective gene. Human blood outgrowth endothelial cells (BOEC) display all the properties needed for successful ex vivo cell therapy. We plan to obtain blood samples from normal research subjects and patients with Von Willebrand Disease in order to isolate blood outgrowth endothelial cells (BOEC) from peripheral blood, and develop a ex vivo gene therapy for Von Willebrand Disease.

The purpose of this phase 3 study is to investigate the efficacy and safety, including immunogenicity and thrombogenicity of prophylactic treatment with recombinant von Willebrand factor (...
This study is testing the use of rhIL-11 (recombinant interleukin 11, Neumega) in individuals with Von Willebrand disease. The purpose is to evaluate: 1. if rhIL-11 corrects VWF (Von Wi...
The objectives of this study are to evaluate the immediate tolerability and safety of rVWF:rFVIII in subjects with Type 3 Von Willebrand Disease after administration of various dosages of ...
von Willebrand disease (VWD) is a hereditary bleeding disorder, caused by a deficiency in the levels and/or function of von Willebrand factor (VWF). Women with VWD appear to be at increased risk of ex...
Type 2B von Willebrand disease is a rare bleeding condition resulting in thrombocytopenia and a reduction in large VWF multimers. It usually has an autosomal dominant pattern of inheritance. We report...
von Willebrand disease (VWD) is the most common inherited bleeding disorder known in humans. Currently, studies investigating the health-related quality of life (HR-QoL) in VWD using standardized tool...
von Willebrand disease (VWD) is the most common inherited bleeding disorder. In VWD patients, large variations in bleeding tendency are observed, which cannot be completely explained by the variation ...
Enhanced von Willebrand factor (VWF) clearance is important in the etiology of both type 1 and type 2 von Willebrand disease (VWD). In addition, previous studies have demonstrated that VWF glycans pla...
A subtype of von Willebrand disease that results from a partial deficiency of VON WILLEBRAND FACTOR.
A subtype of von Willebrand disease that results from qualitative deficiencies of VON WILLEBRAND FACTOR. The subtype is divided into several variants with each variant having a distinctive pattern of PLATELET-interaction.
A subtype of von Willebrand disease that results from a total or near total deficiency of VON WILLEBRAND FACTOR.
A high-molecular-weight plasma protein, produced by endothelial cells and megakaryocytes, that is part of the factor VIII/von Willebrand factor complex. The von Willebrand factor has receptors for collagen, platelets, and ristocetin activity as well as the immunologically distinct antigenic determinants. It functions in adhesion of platelets to collagen and hemostatic plug formation. The prolonged bleeding time in VON WILLEBRAND DISEASES is due to the deficiency of this factor.
Group of hemorrhagic disorders in which the VON WILLEBRAND FACTOR is either quantitatively or qualitatively abnormal. They are usually inherited as an autosomal dominant trait though rare kindreds are autosomal recessive. Symptoms vary depending on severity and disease type but may include prolonged bleeding time, deficiency of factor VIII, and impaired platelet adhesion.
Gene therapy is the use of DNA as a pharmaceutical agent to treat disease. It derives its name from the idea that DNA can be used to supplement or alter genes within an individual's cells as a therapy to treat disease. The most common form of gene th...
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
