About this study

Official title: Evaluation of the GORE® TAG® Thoracic Branch Endoprosthesis (TBE Device) in the Treatment of Lesions of the Aortic Arch and Descending Thoracic Aorta, Zone 2

Read the detailed description

For Zone 2, there are two arms (Aneurysm arm, Non-aneurysm arm) and four cohorts, described as follows: Zone 2 Aneurysm, Zone 2 Dissection, Zone 2 Traumatic Transection, and Zone 2 Other Isolated Lesion. Continued access Subjects were enrolled in the Zone 2 Aneurysm arm. The Zone 2 Aneurysm cohort was the only cohort analyzed with a hypothesis test, however data was collected similarly for all cohorts and for continued access Subjects. Zone 2 Subjects enrolled for analysis were from the United States only.

Conditions: Aortic Aneurysm, Thoracic, Aorta; Lesion
Being tested: GORE® TAG® Thoracic Branch Endoprosthesis
Medical subject headings: Aortic Aneurysm, Thoracic

Study groups in NCT02777593
Study group	Role	What they receive
Zone 2 Aneurysm	Other	Includes primary (hypothesis-driven) aneurysm cohort and continued access. Subjects enrolled for treatment with the TBE device with proximal implantation in aortic Zone 2. Receives: Device: GORE® TAG® Thoracic Branch Endoprosthesis
Zone 2 Non-aneurysm	Other	Includes dissection, traumatic transection and other isolated aortic lesion cohorts. Subjects enrolled for treatment with the TBE device with proximal implantation in aortic Zone 2. Receives: Device: GORE® TAG® Thoracic Branch Endoprosthesis

What is being measured

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

Proportion of Participants With Primary Endpoint Success for Zone 2
Primary Endpoint was composite of the following events: device technical success and absence of aortic rupture, lesion-related mortality, disabling stroke, permanent paraplegia, permanent paraparesis, new onset renal failure requiring permanent dialysis, additional unanticipated post-procedural surgical or interventional procedure related to the device/procedure/withdrawal of the delivery system. Limited to 30 days: disabling stroke, permanent paraplegia, permanent paraparesis, new onset renal failure requiring permanent dialysis.
Measured: 12 Months

Questions about this trial

What is this clinical trial studying?

A study testing GORE® TAG® Thoracic Branch Endoprosthesis in people with Aortic Aneurysm, Thoracic and Aorta; Lesion, run by W.L.Gore & Associates at 35 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 7 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Where is the study taking place?

The record lists 35 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?

What does the primary outcome measure?

Proportion of Participants With Primary Endpoint Success for Zone 2 (time frame: 12 Months). 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 NCT02777593, which also lists 1 linked publication.

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 10 Sep 2026.
