Nectero EAST System Clinical Study

Recruiting now · Phase 2/Phase 3

Conditions studied: Abdominal Aortic Aneurysm

In brief

The purpose of this randomized clinical trial is to treat patients with small to mid-sized abdominal aortic aneurysms (AAA), maximum diameter of 3.5 cm to 5.0 cm, using a locally delivered, single-dose endovascular treatment. The main question the study aims to answer is to demonstrate efficacy of the product for stabilization of these small to mid-sized AAA.The study will compare the treatment group to the typical standard of care for these patients, surveillance. All subjects will be followed at designated intervals at 30/60 days, 6, 12, 18 and 24 months with continued follow-up annually for up to 5 years.

Who can join

Age: 21 and older, up to 85. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Males and females ≥21 to ≤85 years of age. Females must be of non-childbearing potential (menopause or sterilization).
• Subject understands the purpose of the trial, agrees to voluntarily participate in the trial, signs the informed consent and is willing to complete the follow-up according to the requirements of the protocol.
• Infrarenal atherosclerotic fusiform abdominal aortic aneurysm from 3.5 cm to 5.0 cm (male) and 3.5 cm to 4.5 cm (female).
• Infrarenal aortic neck ≥ 15 mm in length and ≤ 29 mm in diameter.
• Overall AAA treatment length (distal renal to distal inferior margin of the aneurysm) not to exceed 130 mm.
• Iliac and femoral artery access, vessel size and morphology allow endovascular access of 14F (or larger) introducer sheaths and catheters.
• Subject meets American Society of Anesthesiology (ASA) grade 1 through 3 criteria, inclusive.
• Subject has > three-year life expectancy.
• Subject is able and willing to comply with all required follow-up clinic visits including CT scans (pre-randomization, 6, 12, 18, 24 months and annually up to 5 years) and blood draws.

You may not qualify if…

• Subject has an acutely ruptured, leaking, dissecting or emergent aneurysm.
• Subject has a symptomatic infrarenal abdominal aortic aneurysm.
• Subject has a mycotic or infected aneurysm.
• Subject has current vascular injury due to trauma.
• Subject's aneurysm is thoracic, suprarenal or juxtarenal.
• Previous surgical or endovascular aneurysm repair for abdominal aortic aneurysm.
• Subject has anatomy of diffuse, ulcerated, or extensive (shaggy) thrombus in the neck of the AAA, that in the opinion of the vascular surgeon/investigator, could result in embolization of the thrombus.
• Subject has anatomy of calcification, and/or plaque within the ilio-femoral arteries or severe infrarenal neck angulation that may compromise or does not allow delivery of the Introducer Sheath or the delivery catheter of the Nectero EAST System.
• Subject has had a myocardial infarction within six (6) months prior to enrollment or elevated CK enzymes or troponin indicative of an evolving MI prior to procedure.
• Subject has current angina, unstable angina, or other active cardiac condition such as congestive heart failure III and IV, atrial arrhythmia, ventricular arrhythmia, or valvular disease, requiring intervention.
• Subject has undergone other major surgery within the 30 days prior to enrollment.
• Subjects with any transient ischemic attack (TIA) or ischemic stroke within 3 months.
• Known allergy to contrast material that cannot be adequately premedicated, delivery system materials (i.e., nylon, polyurethane) and/or pentagalloylglucose (PGG).
• Subject is morbidly obese or has other clinical conditions that severely inhibit X-ray visualization of the aorta.
• Subject has connective tissue/collagen disorder (e.g., Marfan syndrome, vascular Ehlers-Danlos Syndrome, Loeys-Dietz Syndrome, Eaton Syndrome, Bessel-Hagen disease, etc.).
• Known contraindication to undergoing angiography or receiving systemic anticoagulation during the procedure.
• Subject has active systemic infection.
• Subject is participating in another research trial that could interfere with the results of the trial (e.g., drug trial).
• Subject has other medical, social, or psychological problems that, in the opinion of the investigator, preclude them from participation in the trial and to undergo the procedures and evaluations pre- and post-treatment.
• Subject has dialysis dependent renal failure or baseline serum creatinine level >2.5mg/dL or eGFR < 45 mL/min/1.73m2.
• Subjects with aminotransferase (ALT and/or AST) which is ≥1.5x upper limit of normal (ULN) or TB that is our of normal range for the evaluating laboratory.
• Subjects that may not tolerate the lowering of their systolic blood pressure to approximately 100mmHg, should not be considered for this study or treated using the Nectero EAST System.
• Subjects that may not be able to tolerate transient occlusion of the aorta should not be considered for this study.
• Subjects with saccular AAA.
• Subjects with rapidly expanding AAA (previous diameter increases of ≥0.5 cm in 6-months or ≥1 cm in 1 year) as these should be evaluated for immediate repair.
