About this study

Official title: A Post Market Surveillance Multi-center Prospective Study to Evaluate the Safety and Efficacy of the VasQ External Support for Arteriovenous Fistula

This is a prospective single arm study enrolling patients who are scheduled for creation of a new Brachiocephalic or Radiocephalic AV fistula. Up to 80 patients will be enrolled, 50 with upper arm AV fistula and 30 with forearm AV fistula. All patients will be implanted with the VasQ device, a subcutaneous arteriovenous conduit support for vascular access. The follow up period in this study will be for a duration of 12 months, with follow up visits scheduled at 1, 3, 6, 9, and 12 months.

Receives: Device: VasQ

What is being measured

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

  1. Primary patency of AV fistula

    Freedom from any intervention designed to maintain or reestablish patency since device placement and demonstrate flow on Doppler US.

    1 = Success = Intervention free access patency determined by Doppler ultrasound.

    0 = Failure = Access occluded determined by Doppler ultrasound and/or underwent intervention

    Measured: 6 months post AVF creation

Questions about this trial

What is this clinical trial studying?

A study testing VasQ in people with Arterio-Venous Fistula and Kidney Failure, Chronic, run by Laminate Medical Technologies at 11 sites in 4 countries.

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 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

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?

Primary patency of AV fistula (time frame: 6 months post AVF creation). 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 NCT03246984, 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 31 Jan 2024.
