Trial summary

Due to increasing of life expectancy, patients with von Willebrand disease are exposed to age-related pathologies such as cancer or cardiovascular diseases. Management of thrombotic events is challenging given the inherent bleeding risk in von Willebrand disease. Few data are currently available in the literature. Read more about this study

About this study

Due to increasing of life expectancy, patients with von Willebrand disease are exposed to age-related pathologies such as cancer or cardiovascular diseases. Management of thrombotic events is challenging given the inherent bleeding risk in von Willebrand disease. Few data are currently available in the literature.

The aim of the study is to describe the frequency and nature of arterial and venous thromboembolic events and atrial fibrillation in patients with von Willebrand disease in the West of France.

The investigators will perform a retrospective multicenter study conducted in the von Willebrand population of the French West. Von Willebrand adult patients followed in one of the French West medical centers participating in the study, who presented deep vein thrombosis, pulmonary embolism, ischemic stroke, transient ischemic attack, acute coronary syndrome, acute limb ischemia, atrial fibrillation, arteriopathy of the lower limbs, angina will be eligible.

Read the detailed description

Von Willebrand disease is the most common hereditary bleeding disorder. Due to the development of therapies, life expectancy and life quality are increasing in affected patients. However, certain treatments and/or certain comorbidities associated with venous and arterial thrombotic risks may be present in these patients. In the general population, venous thromboembolic disease, arterial thrombosis and atrial fibrillation are frequent. Their management requires the use of antiaggregants and anticoagulant molecules, themselves associated with a bleeding risk. Few data are currently available in the literature concerning the occurrence of venous and arterial thromboembolic events in patients with von Willebrand disease and their management, in the face of a hemorrhagic risk inherent to their pathology and its increase by anti-aggregant treatments and anticoagulants.

The aim of the study is to describe the frequency and nature of arterial and venous thromboembolic events and atrial fibrillation in patients with von Willebrand disease in the West of France.

The investigators will perform a retrospective multicenter study on data conducted in the French West. The study population is composed of patients with von Willebrand disease followed in a reference center in the French West, have consented to be included in the BERHLINGO database (Base d'Etude et de Recherche pour Les INvestigateurs en Hémostase du Grand-Ouest), and who presented deep vein thrombosis, pulmonary embolism, ischemic stroke, transient ischemic attack, acute coronary syndrome, acute limb ischemia, atrial fibrillation, arteriopathy of the lower limbs, angina. Data about von Willebrand disease, risk factors, event, treatment such as antiaggregants and anticoagulants and complications such as hemorrhage or recurrence, will be collected.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To describe the frequency of arterial and venous thromboembolic events and cardiac arrhythmia due to atrial fibrillation in patients with Willebrand disease in the Greater West.

    Occurrence of a thromboembolic event validated by an adjudication committee

    Measured: 12 months

  2. To describe the nature of arterial and venous thromboembolic events and cardiac arrhythmia due to atrial fibrillation in patients with Willebrand disease in the Greater West.

    Occurrence of a thromboembolic event validated by an adjudication committee

    Measured: 12 months

Secondary outcomes (7)
  1. Identify potential risk factors

    identify whether certain risk factors are more prevalent in the population than others

    Measured: 12 months

  2. Number of revascularisation procedures, anticoagulants and antiaggregants prescribed for these conditions

    Prescription of anticoagulant and/or antiaggregant treatment

    Measured: 12 months

  3. Evaluate the nature of treatments prescribed for these pathologies: revascularisation procedures, anticoagulants and antiaggregants

    Revascularisation procedure (endovascular or surgical)

    Measured: 12 months

  4. Evaluate the tolerance of these treatments

    Occurrence of clinical haemorrhage

    Measured: 12 months

  5. Evaluate the effectiveness of these treatments

    Occurrence of a cardio-embolic event

    Measured: 12 months

  6. Evaluate the effectiveness of these treatments

    Occurrence of a thromboembolic recurrence

    Measured: 12 months

  7. Evaluate the effectiveness of these treatments

    Death from haemorrhage and/or thromboembolic causes.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

An observational study of Von Willebrand Diseases, run by University Hospital, Brest at 6 sites in France.

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 6 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 6 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?

To describe the frequency of arterial and venous thromboembolic events and cardiac arrhythmia due to atrial fibrillation in patients with Willebrand disease in the Greater West. (time frame: 12 months). The study lists 2 primary outcomes in all. 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 NCT05773638, which also lists 1 linked publication.

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 6 Feb 2025.
