Nectero EAST System Clinical Study (stAAAble)

May 21, 2026 updated by: Nectero Medical, Inc.

Randomized Controlled Clinical Trial (RCT) of the Nectero EAST System for Small to Mid-Sized Abdominal Aortic Aneurysms (AAA) StaBiLization: Evaluation of Efficacy.

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.

  18. Subject is participating in another research trial that could interfere with the results of the trial (e.g., drug trial).
  19. 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.
  20. Subject has dialysis dependent renal failure or baseline serum creatinine level >2.5mg/dL or eGFR < 45 mL/min/1.73m2.
  21. 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.
  22. 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.
  23. Subjects that may not be able to tolerate transient occlusion of the aorta should not be considered for this study.
  24. Subjects with saccular AAA.
  25. 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.
  26. Subjects who are not suitable for the Nectero EAST System treatment, as determined by the investigator.
  27. Subjects with INR out of normal range for the evaluating laboratory for a subject not on anti-coagulant therapy; or INR >3 for a subject on anti-coagulant therapy.
  28. Subjects with active/acute or a history of unstable chronic liver disease or current liver disease including but not limited to liver transplant, known genetic disorders such as Gilbert syndrome or other liver diseases.
  29. Subjects with cirrhosis (e.g., known history or new clinical diagnosis by elastography with a fibrosis score of F3 or F4 and/or steatosis grade of S3).
  30. Subjects with uncontrolled alcohol use disorder or current alcohol use putting them at risk of liver disease: including consumption of above one standard drink per day for women and two standard drinks per day for men.
  31. Subjects with known right-sided heart failure or pathologically dilated inferior vena cava or hepatic veins indicative of congestive hepatopathy.

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Treatment Arm

Participants assigned to the treatment arm will undergo an endovascular procedure using the Nectero EAST System to deliver the Stabilizer Infusion Solution directly inside the aneurysm. This is a one-time local delivery of the product. Following treatment, surveillance of their AAA will be conducted using CT scans at 6 months, 12 months, 18 months, 24 months, and annually for 5 years.

Intervention: Drug: Stabilizer
Drug: Nectero EAST System
Treated subjects will undergo an endovascular procedure with the Nectero EAST system and receive the Stabilizer Infusion Solution (drug) within 30 days of the study eligibility by CT scan as a one-time local delivery of the drug.
No Intervention: Control Arm
Participants assigned to the control arm will undergo surveillance of their AAA using CT scans at 6 months, 12 months, 18 months, 24 months, and annually for 5 years.
