About this study

Official title: A Pilot Study to Evaluate the Safety and Efficacy of the Apica Access, Stabilization and Closure (ASC™) Device During and After Transcatheter Aortic Valve Implantation (TAVI) Procedures

A pilot study to evaluate the safety and efficacy of the Apica Access, Stabilization, and Closure Device for accessing and closing the left ventricular apex during and after Transcatheter Aortic Valve Implantation (TAVI) procedures. Follow-up assessment will be made post-procedure, at 30 days and 90 days as well as longer term follow-up.

What is being measured

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

  1. Access safety

    Observation of no myocardial tearing on entry of the device

    Measured: Within 2 hours from initial skin incision

  2. Closure safety

    Observation of no acute post-procedural bleeding or pericardial effusion.

    Measured: Within 2 hours from initial skin incision

Secondary outcomes (1)
  1. Investigational device performance: LV function

    % LVEF no worse than baseline as assessed by echocardiography

    Measured: 24 hours, 30 days and 90 days post-procedure

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Apica Cardiovascular ASC Access, Stability and Closure Device in people with Aortic Valve Stenosis, run by Apica Cardiovascular Limited.

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 9 inclusion and 24 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 Jun 2014. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Access safety (time frame: Within 2 hours from initial skin incision). 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 Jun 2014.
