Trial summary

There are no endoluminal stent systems available on the Chinese market for the effective treatment of aortic arch lesions (involving aortic arch aneurysms, aortic coarctation, aortic pseudoaneurysms, aortic ulcers, and intermural hematomas), and therefore this study is intended to be a prospective, single-arm study.

Who cannot join

  • Patients with general or local infections that may increase the risk of endovascular graft infection;

About this study

Official title: A Study on the Concave Supra-arch Branched Stent-Graft System for Treatment of Aortic Arch Diseases

There are no endoluminal stent systems available on the Chinese market for the effective treatment of aortic arch lesions (involving aortic arch aneurysms, aortic coarctation, aortic pseudoaneurysms, aortic ulcers, and intermural hematomas), and therefore this study is intended to be a prospective, single-arm study.

Read the detailed description

The physician shall strictly follow the clinical study protocol and shall not deviate from or substantially change the protocol. However, in case of emergency such as immediate risk to the subjects, which needs to be eliminated immediately, it may be reported in written form afterwards. During the course of the study, documents such as amendments to the clinical study protocol and informed consent, requests for deviation, and resumption of the suspended clinical study shall be subject to the written approval of the Ethics Committee.

Being tested

What is being measured

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

  1. Immediate technical success rate

    Immediate technical success refers to the successful delivery system to a predetermined location, the successful deployment of the system and the safe withdrawal of the delivery system from the body, and the branch arteries were successfully reconstructed.

    Measured: Immediate intraoperative

Questions about this trial

What is this clinical trial studying?

A study testing Concave Supra-arch Branched stent-graft system in people with Aortic Dissection and Aneurysm, Aortic Arch, run by China National Center for Cardiovascular Diseases at 3 sites in China.

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 18 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: status not confirmed, as of the sponsor's last update on 11 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in China. 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?

Results are not available in the source record.

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?

Immediate technical success rate (time frame: Immediate intraoperative). 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 11 Oct 2023.
