Trial summary

The objective of this study is to define the repeatability and reproducibility of quantifying flow-mediated dilation (FMD) of the brachial artery (BA) using the AngioDefender (AD) methodology. Repeatability will be assessed by repeat AD testing of the same subject 1 hour apart, using the same AD device and operator. Read more about this study

About this study

Official title: Vascular Reactivity Assessment by AngioDefender -- A Repeatability and Reproducibility Study

The objective of this study is to define the repeatability and reproducibility of quantifying flow-mediated dilation (FMD) of the brachial artery (BA) using the AngioDefender (AD) methodology.

Repeatability will be assessed by repeat AD testing of the same subject 1 hour apart, using the same AD device and operator.

Reproducibility will be assessed by comparing FMD scores obtained for the same subject, but using different AD devices and operators.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AngioDefenderDevice

    Repeatability will be assessed by repeat AngioDefender (AD) testing of the same subject 1 hour apart, using the same AD device and operator.

    Reproducibility will be assessed by comparing FMD scores obtained for the same subject, but using different AD devices and operators.

Study groups in NCT02641197
Study groupRoleWhat they receive
AngioDefenderExperimentalThe AngioDefender device uses a novel, proprietary software algorithm to analyze pulse wave amplitude data collected before and after brachial artery occlusion by a standard upper arm pneumatic blood pressure cuff. The procedure is non-invasive and does not employ ultrasound.
Receives: Device: AngioDefender

What is being measured

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

  1. Change from baseline %flow-mediation dilation (%FMD) at 1 hour

    Repeat AD testing of the same subject 1 hour apart on 4 consecutive days (operators and/or AD devices change each day)

    Measured: Daily x 4 consecutive days

Secondary outcomes (2)
  1. Reproducibility of multiple %FMD determinations by AngioDefender

    Repeat AD testing of the same subject over 4 consecutive days using different operators and/or AD devices each day

    Measured: Daily x 4 consecutive days

  2. Incidence of emergent adverse device effects (ADEs) according to CTCAE v4.03

    Spontaneous ADEs reported by the subject and inquiry into emergence of expected/unexpected ADEs

    Measured: 4 consecutive days (maximum 5 days)

Questions about this trial

What is this clinical trial studying?

A study testing AngioDefender in people with Cardiovascular Diseases, run by Everist Genomics, Inc at 2 sites in Canada.

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 8 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 5 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Canada. 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?

Change from baseline %flow-mediation dilation (%FMD) at 1 hour (time frame: Daily x 4 consecutive days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 5 Feb 2018.
