Study summary

The purpose of this clinical study is to evaluate the safety and device performance of the Nellix® EndoVascular Aneurysm Sealing System (Nellix System) for the treatment of infrarenal abdominal aortic aneurysms.

Read the detailed description

This is a multicenter, multi-country prospective, single-arm, non-randomized clinical trial. The comparative control arm is a combination of patient data drawn from the abdominal aortic aneurysms (AAA) open surgical control arms of four commercially approved AAA devices as part of the Society of Vascular Surgeons. Patients enrolled in this study will be pre-screened and have a diagnosis of an infrarenal AAA with or without the need for treatment of iliac artery aneurysm, are candidates for endovascular repair, and meet the eligibility criteria. Patients enrolled in the study will participate in follow-up visits 31 days, 6 months and at 1 year following the index procedure. At the follow-up visits there will be a clinical assessment, blood collection, and abdominal CT imaging of the patient.

Inclusion criteria

  • At least 18 years of age
  • form understood and signed and patient agrees to all follow-up visits
  • Is able and willing to comply with clinical follow-up requirements for one year
  • Is able and willing to undergo Contrast-Enhanced Spiral CT scans
  • Is a candidate for endovascular repair of an infrarenal aortic aneurysm with or without an iliac aneurysm with at least one of the following;

    1. aneurysm ≥ 4.5 cm in diameter, or
    2. aneurysm is twice the diameter of the normal infrarenal aorta, or
    3. aneurysm is growing at a rate of ≥ 10 % per year
  • Non-aneurysmal aortic neck length ≥ 5mm below the most inferior renal artery
  • Proximal aortic neck diameter between 16 and 36mm
  • Aortic neck angulation to the sac ≤ 60
  • Common iliac artery diameter 8 to 35mm bilaterally
  • Aneurysm blood lumen diameter ≤ 60mm
  • Iliac and femoral arteries suitable for endovascular access with the Nellix System

Exclusion criteria

Exclusion Criteria:

  • ≤ 1 year
  • Dissecting, ruptured, or leaking aneurysm (blood outside the aorta), has sustained recent trauma, is symptomatic, or is non-degenerative
  • Aneurysm is thoraco-abdominal, suprarenal and/or mycotic
  • Thoracic aneurysm ≥ 4.5cm in diameter
  • AAA requires treatment that would result in bilateral occlusion of the internal iliac arteries
  • Presence of mural thrombus > 50% circumferentially in aortic neck
  • Iliac aneurysm blood lumen diameter > 35mm
  • Active infection, vasculitis, or systemic connective tissue disease (e.g., Rheumatoid arthritis, scleroderma, Marfan's syndrome, Ehlers-Danlos disease) at time of procedure
  • History of prior treatment of abdominal aortic or iliac artery aneurysm disease
  • Femoral or iliac artery occlusive disease such that device delivery is not possible
  • Vascular access for delivery of device requires placement of vascular conduit or is through an established vascular graft
  • Receiving dialysis
  • History of hypercoagulability
  • Allergy to IV contrast
  • Serum creatinine level >2.0 mg/dL (or equivalent)
  • Patient is pregnant or nursing
  • Patient is currently enrolled in an drug or device trial
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  1. Safety- Number of Major Adverse Events

    The primary safety endpoint is defined as the incidence of Major Adverse Events (MAE) through 30 days after the index procedure.

    Time frame: 30 day

  2. Device Performance

    The primary performance endpoint is technical success defined as successful delivery and deployment of the device and freedom from open surgical conversion at 30 days.

    Time frame: 30 days

Secondary outcomes

  1. All Cause Mortality

    Any death occurring during the study period, regardless of cause

    Time frame: 12 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 9, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
