Von Willebrand DiseasesWITECMO-HNCT03070912
Frequency of Hemorrhages Associated With the Functional Anomalies of Willebrand Factor in Emergency Patients
An observational study of Von Willebrand Diseases, run by University Hospital, Lille at 7 sites in France.
Trial summary
ECMO has improved the outcome of heart or respiratory failure and carcinogenic shock and are increasingly used. However bleeding complications occurring in up to 50% of patients are poorly understood and worsen the overall results. Read more about this study

About this study
Official title: Study of the Frequency of Hemorrhages Associated With the Functional Anomalies of Willebrand Factor in Emergency Patients of a Veino Arterial or Veinous ECMO
ECMO has improved the outcome of heart or respiratory failure and carcinogenic shock and are increasingly used. However bleeding complications occurring in up to 50% of patients are poorly understood and worsen the overall results. The aim is to investigate the occurence of bleeding and its frequency according to the type of ECMO either veno-arterial or veno-venous. The investigators also want to assess the relation of bleeding with von Willebrand Factor defects.

What is being measured
The primary outcome is the main question the study is designed to answer.
Frequency of major bleeding
Number of major bleeding events (BARC classification ) occurring within the time course of support by ECMO
Measured: During ECMO support, up to 3 weeks after implantation
Secondary outcomes (8)
Number of Participants With Abnormal VWF functional activities and multimeric profile according to the type of ECMO support (VA- or VV-ECMO)

Measured: 1 hour, 24 hours and day seven after implantation
Number of Participants With Abnormal VWF functional activities and multimeric profile before and after the first reduction in VA-ECMO flow rate
Willebrand Factor abnormalities according to residual arterial pulsatility levels under VA-ECMO
Measured: During ECMO support, up to 3 weeks after implantation
Number of Participants With Abnormal VWF functional activities and multimeric profile in 2 groups defined by the level of pulse pressure measured before ECMO weaning: high (> median) or low (< median) pulse pressure

Questions about this trial
What is this clinical trial studying?
An observational study of Von Willebrand Diseases, run by University Hospital, Lille at 7 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 3 inclusion and 5 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: finished, as of the sponsor's last update on 28 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in France. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Frequency of major bleeding (time frame: During ECMO support, up to 3 weeks after implantation). 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 NCT03070912, which also lists 2 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 28 Nov 2025.
