About this study

First clinical experience on the ACURATE TF™ Transfemoral Aortic Bioprosthesis Implantation in Patients with Severe Aortic Stenosis to collect human data pertaining to the safety and performance of the device from three different cohorts

Read the detailed description

A prospective, multicenter, "CE-approval cohort" analysis with the Symetis ACURATE TF™ Transfemoral Aortic Bioprosthesis for minimal invasive implantation via transfemoral access to treat patients with severe aortic stenosis where conventional aortic valve replacement (AVR) via open heart surgery is considered to be associated with high risk, to evaluate the feasibility and performance of the implantation at 30-Days and at 1-Year Follow-up.

Being tested
ACURATE TF™

What participants receive

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

  • ACURATE TF™Device

    Also called ACURATE TF™Transfemoral Aortic Bioprosthesis and Delivery System

    ACURATE TF™Transfemoral Aortic Bioprosthesis is intended for subjects with severe symptomatic Aortic Stenosis and are considered high risk for surgical conventional Aortic Valve Replacement .

What is being measured

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

  1. Freedom from all-cause mortality

    Rate of all-cause mortality

    Measured: 30-Day Follow-up

Secondary outcomes (4)
  1. Rate of MACCE (major cardiac and cerebrovascular event) related to the ACURATE TF™ Transfemoral Aortic Bioprosthesis and Delivery System.

    Rate of major cardiac and cerebrovascular event (MACCE) at 30 days and at 12 months follow-up related to ACURATE TF™ Transfemoral Aortic Bioprosthesis and Delivery System and defined as all cause death, myocardial infarction, re-intervention and stroke.

    Measured: 30-Days and 12 Months Follow-up

  2. Change in NYHA class over time

    Functional improvement from baseline NYHA classification at 30 day and at 12 month follow-up.

    Measured: 30-Day and 12-Month

  3. Procedural success during device implantation

    Procedural Success defined as stable study device placement at intended site and adequate device functioning immediately post-implantation, confirmed by angiography and echocardiography and without intra-procedural mortality.

    Measured: intraoperative

  4. Device success

    Device success is defined as adequate functioning of the study device as confirmed by angiography and/or echocardiography.

    The following data points will be analyzed for adequate functioning of the study device:

    • Effective orifice area and index (EOA)
    • Peak jet velocity
    • Transvalvular aortic gradient (mean)
    • Paravalvular and intravalvular (central) leak
    • Aortic Insufficiency
    • Valve function and morphology

    Measured: 30-Day and 12-Month Follow-up

Questions about this trial

What is this clinical trial studying?

A study testing ACURATE TF™ in people with Symptomatic Aortic Stenosis, run by Symetis SA at 6 sites in 3 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 7 inclusion and 27 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 27 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Germany, Brazil, Japan. 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?

Freedom from all-cause mortality (time frame: 30-Day Follow-up). 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 27 Nov 2018.
