|Condition or disease||Intervention/treatment||Phase|
|Abdominal Aortic Aneurysm||Device: AFX EVAR AAA Graft System Device: FDA Approved EVAR AAA Graft Systems||Not Applicable|
This trial is a prospective, randomized, multi-center trial, intended to evaluate the outcomes of contemporary EVAR (Endovascular Aneurysm Repair) in a real world population. The trial is designed to compare the anatomically stabilized AFX Endograft System to a reference group of proximally fixated EVAR devices. Patients will be randomized between the two groups.
Randomization will be 1:1. Each investigator will select one comparator device of their choice before enrolling the first patient. The study will sequentially evaluate non-inferiority and superiority hypotheses.
Up to 80 sites with experience in EVAR and up to 800 subjects will participate in this study.

- Migration (≥ 10mm)
- Aneurysm Enlargement (≥ 5mm)
- Endograft Limb Occlusions
- Reinterventions for device- or aneurysm-related complications
- The Number of MAEs [ Time Frame: At 30 days, 12 months, and annually up to five years ]Major Adverse Events
- The Number of Aneurysm Related Complications (ARC) [ Time Frame: Post 12 Months up to Five Years ]ARC is a composite outcome
- The Number of Participants With Aneurysm Related Mortality [ Time Frame: Up to Five Years ]Death related to the aneurysm
- Number of Endoleaks Classified by Type [ Time Frame: Up to Five Years ]All Endoloeaks
- Loss of Neck Apposition as Measured by Length in mm [ Time Frame: Up to Five Years ]Loss of Neck Apposition as measured by length in mm
- Number of AAA Related Secondary Procedures [ Time Frame: Up to Five Years ]Number of AAA related secondary procedures
- Number of Device Integrity Events [ Time Frame: Up to Five Years ]Number of device integrity events from device fractures and technical observations related to the stent graft
