About this study

Official title: ACURATE™ Transapical Aortic Bioprosthesis for Implantation in Patients With Severe Aortic Stenosis

The purpose of this study is to evaluate safety of the study device and study device performance in patients presenting with severe aortic stenosis who are considered to be high risk for open surgical repair.

Read the detailed description

A single arm, prospective, multicenter, non-randomized, and open trial, up to 5 years follow-up with the Symetis ACURATE TA™ which is an aortic bioprosthesis for minimal invasive implantation vie transapical access to treat patients with severe symptomatic aortic stenosis where conventional aortic valve replacement (AVR) via open heart surgery is considered to be associated with high surgical risk for evaluating safety and performance of the implantation and safety at 30-D follow-up.

What participants receive

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

  • ACURATE TA™Device

    Also called ACURATE TA™ Transapical Aortic Bioprosthesis and Delivery System

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

What is being measured

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

  1. Freedom from all-cause mortality at 30 day Follow Up

    The primary study objective is to evaluate the safety of the ACURATE™ Transapical Aortic Bioprosthesis at 30 days post-procedure in patients presenting with severe aortic valve stenosis at high risk for conventional AVR surgery.

    Measured: 30-Day Follow-up

  2. Freedom from all-cause mortality at 12 months Follow Up

    The primary study objective is to evaluate the safety of the ACURATE™ Transapical Aortic Bioprosthesis at 12 months post-procedure in patients presenting with severe aortic valve stenosis at high risk for conventional AVR surgery.

    Measured: 12 months Follow-Up

Secondary outcomes (5)
  1. Rate of Major Adverse Valve-Related Events (MAVRE) at 30 days and at 12 month follow up related to the study device as defined as;

    2.1 Structural valve deterioration

    2.2 Non-structural dysfunction of the implanted study device

    2.3 Valve thrombosis, embolism, bleeding event

    2.4 Operated valve endocarditis

    2.5 Re-intervention on the implanted device

    2.6 Valve-related mortality

    2.7 Need for new permanent pacemaker or defibrillator within 14 days

    Measured: 30-Days and at 12 Months Follow-up

  2. Rate of Major Adverse Cardiac and Cerebrovascular-Related Events (MACCE) at 30 days and at 12 Month and defined as cardiovascular death, myocardial infarction and stroke.

    Defined as cardiovascular death, myocardial infarction and stroke

    Measured: 30-Day and 12-Month

  3. Functional Improvement from baseline

    per NYHA functional classification

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

  4. Procedural success

    defined as stable study device placement at intended site and adequate device functioning immediately post-implantation, confirmed by angiography and echocardiography as assessed at a Core Lab and without intraprocedural mortality.

    Measured: 24 hours Post-Procedure

  5. Device success at 30 Days and 12 Month follow-up as defined as adequate functioning of the study device as confirmed by angiography and/or echocardiography as assessed at a CoreLab.

    Device success at 30 Days and 12 Month follow-up as defined as adequate functioning of the study device as confirmed by angiography and/or echocardiography as assessed at a CoreLab. The following datapoints will be analyzed:

    6.1 Effective orifice area and index (EOA/EOAI)

    6.2 Transvalvular Gradients (Peak and mean)

    6.3 Paravalvular and intravalvular (Central) leaks

    6.4 Aortic Insufficiency

    6.5 LV function and hemodynamics

    6.6 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 TA™ in people with Aortic Symptomatic Stenosis, run by Symetis SA at 5 sites in Germany.

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 6 inclusion and 30 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 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Germany. 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 at 30 day Follow Up (time frame: 30-Day Follow-up). The study lists 2 primary outcomes in all. 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 Jul 2023.
