What is the purpose of this trial?

This trial tests a new device, the GORE® EXCLUDER® Conformable AAA Endoprosthesis, to determine its safety and effectiveness in treating abdominal aortic aneurysms (a bulge in the main artery that carries blood from the heart to the rest of the body). The study focuses on individuals with a specific type of aneurysm that hasn't ruptured but is either large, growing quickly, or causing symptoms. Participants should have aneurysms with certain size and shape characteristics and must be able to undergo the procedure and follow-up. The trial includes two groups: one for individuals with a certain neck angle in their aneurysm and another for those with a different neck angle. As an unphased trial, this study allows participants to contribute to the development of innovative treatments for aneurysms.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that the GORE® EXCLUDER® Conformable AAA Endoprosthesis is safe for treating abdominal aortic aneurysms?

Research has shown that the GORE® EXCLUDER® Conformable AAA Endoprosthesis is generally safe for treating certain types of abdominal aortic aneurysms, which are bulges in the large artery that carries blood from the heart. In one study, researchers monitored patients for five years, and the results indicated that the device was safe and effective for aneurysms in specific areas of the aorta. No unexpected safety issues arose during this period.

Additionally, another study with one-year results also supports its safety, showing positive outcomes for patients. These findings suggest that the treatment is well-tolerated. Such long-term data encourages those considering joining a clinical trial. ^{1 2 3 4 5}

Why are researchers excited about this trial?

The GORE® EXCLUDER® Conformable AAA Endoprosthesis is unique because it offers a new approach to treating abdominal aortic aneurysms, particularly in patients with challenging anatomy. Unlike traditional endovascular stent grafts, this device is designed to conform to short or highly angulated aortic necks, which can be difficult to treat with standard options. Researchers are excited about this treatment because its flexibility and adaptability could lead to better sealing and fixation, potentially reducing the risk of complications and improving patient outcomes.

What evidence suggests that the GORE® EXCLUDER® Conformable AAA Endoprosthesis is effective for treating abdominal aortic aneurysms?

Studies have shown that the GORE® EXCLUDER® Conformable AAA Endoprosthesis effectively treats abdominal aortic aneurysms, which are bulges in the main blood vessel in the belly. In one study, only 11.3% of patients required another procedure after receiving this device, and only 10.3% experienced their aneurysm growing by 5mm or more over five years. Another study found that after one year, the device performed well and met the trial's goals. In this trial, participants will receive treatment with the GORE® EXCLUDER® Conformable AAA Endoprosthesis in different substudies based on specific aneurysm characteristics. These results suggest that the endoprosthesis can safely manage and control aneurysms in the abdominal aorta. ^{1 2 3 5 6}

What Are the Treatments Tested in This Trial?

Interventions

• GORE® EXCLUDER® Conformable AAA Endoprosthesis

Trial Overview The study tests the GORE® EXCLUDER® Conformable AAA Endoprosthesis's safety and effectiveness in treating infrarenal abdominal aortic aneurysms. The endoprosthesis performance will be evaluated against specific goals to determine its suitability as a treatment option.

How Is the Trial Designed?

Group I: Short Neck Substudy Experimental Treatment 1 Intervention

Subjects with abdominal aortic aneurysms having infrarenal aortic neck angulation ≤ 60˚ and infrarenal aortic neck length ≥10 mm treated with the GORE® EXCLUDER® Conformable AAA Endoprosthesis.

Group II: High Neck Angulation Substudy Experimental Treatment 1 Intervention

Subjects with abdominal aortic aneurysms having infrarenal aortic neck angulation \> 60˚ and ≤ 90˚ and infrarenal aortic neck length ≥10 mm treated with the GORE® EXCLUDER® Conformable AAA Endoprosthesis.

Published Research Related to This Trial

The GORE EXCLUDER Conformable AAA Endoprosthesis has been successfully implanted in humans, addressing challenges in endovascular repair for abdominal aortic aneurysms, particularly in patients with short or highly angulated necks.

This innovative device offers features like repositionability and optional angulation control, which may enhance the accuracy of placement and improve long-term outcomes compared to previous generations of endografts.

Initial human experience with the GORE EXCLUDER Conformable AAA Endoprosthesis. Rhee, R., Peterson, B., Moore, E., et al.[2020]

In a clinical trial involving 80 patients with abdominal aortic aneurysms, the GORE EXCLUDER Conformable AAA Endoprosthesis system demonstrated 100% technical success and 98.5% effectiveness in preventing aneurysm-related events after one year.

The device showed excellent safety, with no major adverse events reported within the first 30 days, including no deaths or serious complications, and 100% freedom from aneurysm-related mortality over the 12-month follow-up.
