About this study

The primary objective of this trial is to determine whether the Talent Thoracic Stent Graft, an investigational device, is a safe and effective method of treating thoracic aortic aneurysms (abnormal ballooning of the vessel wall) and other thoracic lesions (dissections, transections, pseudoaneurysms, penetrating ulcers, etc.). The endovascular method is a substitute for the major operation that is performed to treat the lesions.

Read the detailed description

The endovascular method consists of the insertion of catheters (vinyl tubes) into both groin arteries. These catheters then allow positioning of artificial tubes or stent graft(s) into the diseased blood vessel without the need for major surgery which involves opening the chest. The blood vessel problem (thoracic aortic aneurysm/lesion) will be treated using an artificial bypass tube (stent graft) that will be placed inside the diseased artery. The stent graft(s) that will be used are made of polyester graft fabric sewn to a self-expanding nickel-titanium (Nitinol) wire frame and is manufactured by Medtronic AVE, Santa Rosa California.

Aneurysms/lesions can be located in any position along the length of the aorta. This study evaluates only aneurysms/lesions that occur in the descending part of the thoracic aorta as it traverses the chest and enters the abdominal cavity. The risk of thoracic aneurysms/lesions is that they rupture without warning. The risk of rupture increases as the aneurysm size increases. Following rupture, almost all patients expire within the first 24 hours. For this reason treatment of thoracic aneurysms/lesions is recommended by conventional surgical means if the patient is a candidate for an operation. The conventional operation involves occluding the aorta and replacing the aneurysm with a cloth tube that is sewn to replace the diseased part of the aorta. The major surgery and occlusion of the aorta that is part of the conventional surgery is directly related to several complications that have been reported in the literature. In addition, many patients are too ill for conventional surgery due to concomitant illnesses.

After the procedure, the patient will be followed at regular intervals (pre-discharge, 1 month, 6 months, 12 months and every year thereafter for life) as part of the evaluation of the experimental treatment. During this time, the patient will have several tests performed to evaluate the function of the repair. The tests will include clinical examination, x-rays of the chest and spiral CT scan. The experimental part is the placement of the TALENT Stent-Graft System using the catheter (endovascular) methods. The risk of the experimental catheter bypasses is that the procedure may not be successful. In most cases, this would require a standard operation to repair the problem. Sometimes there are other risks such as injury to the vessels. Small pieces of diseased arteries may be dislodged which may require removal. Bleeding may occur from introduction sites, and rarely, infection may develop. If a catheter bypass is unsuccessful, there can be added discomfort because the procedure may last longer.

The benefits of the procedure are that the patient might avoid some of of the pain and discomfort associated with standard operations. Major surgery is avoided and hospital stay may be much shorter. Patients may be able to return to usual daily activities sooner. In addition, patients who are too high risk for conventional surgical treatment can have their aneurysm treated using the endovascular graft if their anatomy is appropriate

Questions about this trial

What is this clinical trial studying?

A study testing Endoluminal treament of thoracic lesions in people with Thoracic Aortic Aneurysms and Thoracic Transections, run by Rodney A. White, M.D. at 1 site 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 15 inclusion and 7 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 14 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 14 Sep 2023). 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 Endoluminal Treatment of Thoracic Lesion (time frame: Throughout study completion, an average of 1 year). 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 14 Sep 2023.
