About this study

Official title: Evaluation of the GORE® TAG® Thoracic Branch Endoprosthesis in the Treatment of Proximal Descending Thoracic Aortic Aneurysms

The purpose of this study is to assess the feasibility of the use of the GORE® TAG® Thoracic Branch Endoprosthesis to treat aneurysms involving the proximal Descending Thoracic Aorta (DTA)

Read the detailed description

The GORE® TAG® Thoracic Endoprosthesis (TAG® Device) received premarket approval (PMA) for use in endovascular aneurysm repair of the descending thoracic aorta (DTA) on 23-Mar-2005 under P040043, and design changes that resulted in the conformable GORE® TAG® Thoracic Endoprosthesis (CTAG Device) received premarket approval for the treatment of aneurysms of the DTA on 23-Aug-2011 (P040043/S039). The TAG® Device and CTAG Device are intended to exclude an aneurysm from the blood circulation in patients diagnosed with DTA aneurysms. However, endovascular-only treatment options for patients with aneurysms approaching the aortic arch are limited as current stent graft technology would require coverage of the left subclavian artery (LSA) which may result in the need for a surgical revascularization procedure. This prompted the creation of the GORE® TAG® Thoracic Branch Endoprosthesis (previously known as Branched TAG® Device), which was evaluated in this study under IDE G130120 for Zone 2 aneurysms of the DTA.

What is being measured

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

  1. Number of Participants With Successful Study Device Access

    Access to the aneurysm and target landing zone location is obtained via conventional vascular access and endovascular techniques.

    Measured: During treatment procedure (day 0)

  2. Number of Participants With Successful Study Device Deployment

    Absence of deployment failure will be considered a successful deployment. Deployment failure will be considered the failure of any Branched TAG® Device component (Aortic Component, Aortic Extender, or SB Component) to be released from the delivery catheter resulting in a serious adverse event (SAE) due to mechanical failure or use error.

    Measured: During treatment procedure (day 0)

  3. Number of Participants With Primary Procedural Side Branch Patency as Assessed by Angiography

    The presence of forward flow through the implanted Side Branch Component into the target branch vessel.

    Measured: At conclusion of the treatment procedure (day 0)

Secondary outcomes (2)
  1. Number of Participants With 1 Month Side Branch Primary Patency Assessed by an Independent Core Lab

    Measured: 1 Month

  2. Number of Participants Without 1 Month Device Related Endoleaks Assessed by an Independent Core Lab

    Device-related endoelaks are defined as the presence of contrast within the aneurysm sac originating from the junction between any Branched TAG® Device component and the adjacent tissue (endoleak type IA or IB) OR the junction between the Aortic Component and either the SB Component or the Aortic Extender (type III endoleak).

    Measured: 1 Month

Questions about this trial

What is this clinical trial studying?

A study testing GORE® TAG® Thoracic Branch Endoprosthesis in people with Aortic Aneurysm, Thoracic, run by W.L.Gore & Associates at 6 sites in United States.

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 22 inclusion and 31 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 9 Sep 2022. 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 United States. 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?

Yes. Results are posted in the registry (first posted 2 Aug 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Successful Study Device Access (time frame: During treatment procedure (day 0)). The study lists 3 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 9 Sep 2022; AzTrials last refreshed its copy on 7 Nov 2026.
