About this study
Official title: Von Willebrand Disease in the Netherlands - Prospective Study (WiN-Pro)
The primary aim of this study is to prospectively investigate the current bleeding tendency of children and adults with VWD.
Read the detailed description
Von Willebrand disease (VWD) is the most common inherited bleeding disorder, and is characterized by a defective platelet adhesion and aggregation. VWD is caused by a reduced (type 1), an abnormal function (type 2) or a complete absence (type 3) of von Willebrand factor (VWF).
In recent years, large retrospective cohort studies have provided valuable insights on the clinical presentation, bleeding phenotype, quality of life, diagnostics, genetics and treatment of patients with VWD. One of these large studies is the von Willebrand in the Netherlands (WiN) study, which is a nationwide cross sectional study of moderate and severe von Willebrand disease patients, that was initiated in 2007. Over 800 VWD patients were included in the WiN study, which was about 80% of all known VWD patients in the Netherlands. Although the WiN study and large retrospective studies in other countries provided important insights in understanding VWD, some significant challenges remain and large prospective studies are lacking to provide answers.
All large retrospective cohort studies have assessed the bleeding phenotype of patients with VWD using bleeding scores or retrospective questionnaires. Bleeding scores calculate the sum of all bleeding episodes during lifetime. Therefore, they provide useful information on the bleeding tendency during lifetime. However, bleeding scores do not provide information on the change of bleeding tendency. If a patient had a period in his or her lifetime in which he or she had many bleeding episodes, then the bleeding score is high. Though, the patient could have had those bleeds 30 years ago and did not have a bleeding episode since then. Therefore, bleeding scores do not provide information on the current bleeding phenotype of VWD patients. Furthermore, previous studies provided limited information on the frequency of mild bleedings, like gum bleeding or epistaxis, that occur in daily life but do not require therapy. Nevertheless, these bleeding episodes can cause a major impairment in quality of life. This is especially important in children, because school-going children with VWD have a lower quality of life and have a different bleeding tendency, characterized by more cutaneous bleeding (81%), oropharyngeal bleeding (64%) and epistaxis (56%).
Therefore, the primary aim of this study is to prospectively investigate the current bleeding tendency of children and adults with VWD.

Questions about this trial
What is this clinical trial studying?
An observational study of Von Willebrand Disease, run by Erasmus Medical Center at 9 sites in Netherlands.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 17 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Frank WG Leebeek, MD, PhD (+31107031369, f.leebeek@erasmusmc.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Bleeding rate (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03521583, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Aug 2020.
