About this study

The goal of the ACCURACY study is to assess the differences, if any, in FFR measurements made by the OptoWire Deux FFR guidewire by comparison of simultaneous data of two different OptoWire DeuxTM guidewires (group 1). In addition, the investigators will compare (group 2) the FFR measurements obtained from an OptoWire Deux FFR guidewire and compare it to the FFR measurement by a VERRATA-TM guidewire to assess coronary stenosis in the routine clinical practice.

Read the detailed description

This is a single center, prospective, non-blinded clinical investigation enrolling consecutive patients with coronary lesion candidate for FFR assessment. The study aim to assess the differences, if any, in FFR measurements made by the OptoWire Deux FFR guidewire by comparison of simultaneous data of two different OptoWire DeuxTM guidewires (group 1, n=30). In addition, The investigators will compare (group 2, n=15) the FFR measurements obtained from an OptoWire Deux FFR guidewire and compare it to the FFR measurement by a VERRATA-TM guidewire to assess coronary stenosis in the routine clinical practice. The clinical investigation will be conducted in the Centre Hospitalier de l'Université de Montréal (CHUM). No clinical follow-up is requested after the end of the procedure.

Being tested
Drift assessment of OptoWire Deux FFR wire (1), Drift assessment of OptoWire Deux FFR wire (2)
Medical subject headings

What participants receive

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

  • Drift assessment of OptoWire Deux FFR wire (1)Device

    Simultaneous data of two different OptoWire DeuxTM guidewires (group 1) to assess a single coronary stenosis and detect any difference if any.

  • Drift assessment of OptoWire Deux FFR wire (2)Device

    Simultaneous data of one Optowire Deux TM guide wires and one VERRATA-TM FFR wire (group 2) to assess a single coronary stenosis and detect any difference if any.

What is being measured

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

  1. delta FFR

    To assess the magnitude of reading delta from wire to wire in a percutaneous coronary intervention

    Measured: Day 1

Secondary outcomes (5)
  1. Drift recording

    The rate of significant drift, defined as Pd/Pa <0.97 or >1.03

    Measured: Day 1

  2. Delta from guidewire to guidewire

    Assess the magnitude of reading delta from guidewire to guidewire prior to equalization.

    Measured: Day 1

  3. Stents

    The number of stents used.

    Measured: Day 1

  4. Stents on FFR wire

    The number of stents placed over an OptoWire DeuxTM guidewire.

    Measured: Day 1

  5. Workhorse guidewire

    Number of Workhorse guidewire used.

    Measured: Day 1

Questions about this trial

What is this clinical trial studying?

A study testing Drift assessment of OptoWire Deux FFR wire (1) and Drift assessment of OptoWire Deux FFR wire (2) in people with Coronary Artery Disease and Coronary Stenosis, run by Centre hospitalier de l'Université de Montréal (CHUM) at 1 site 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 1 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: finished, as of the sponsor's last update on 20 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

delta FFR (time frame: Day 1). 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 NCT03815032, 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 20 Jul 2020.
