Study summary

The goal of this observational study is to collect clinical information on how safe, and how well the NEXUS Aortic Arch Stent Graft System and the Custom-Made NEXUS DUO™ Aortic Arch Stent Graft System work for the treatment of aortic aneurysms, in the standard-of-care setting.

The main question[s] it aims to answer are:

  • Early mortality
  • Safety outcomes throughout the study
  • Device failure throughout the study
  • Procedural and hospitalisation information Participants will be treated per institutional standard of care Follow-up information will be collected through to five years.

Study population

Patients diagnosed with a thoracic aortic aneurysm or chronic dissection extending to or involving the aortic arch and who are considered candidates for the endovascular repair.

Eligibility criteria

  1. Male and female age ≥18 years
  2. The subject is indicated for implant of the NEXUS Aortic Arch System in accordance with the current IFU, or
  3. The subject is indicated for implant of the custom-made NEXUS DUO Aortic Arch System in accordance with the current IFU, or
  4. The subject has been already implanted, after February 2019, with the NEXUS or the NEXUS DUO according to the relevant IFU
  5. The subject is able and willing to provide to participate in the study.
  6. Subject is not currently enrolled in another study or registry that would directly interfere with the current study, except if the subject is participating in a mandatory government registry, or a purely observational registry with no associated treatments. Each instance should be brought to the attention of the sponsor to determine eligibility.
  7. In the opinion of the Investigator, exceeds one year
  8. The subject is not pregnant or planning to become pregnant.
  9. In the physician's opinion, subject's renal function is stable for the NEXUS procedure.
  10. In the opinion of the investigator, subject does not have co-morbidities or planned surgeries that will interfere with the implant of the device, e.g., major cardiac surgery or interventional procedure in the last 90 days, MI or cerebral vascular accident (CVA) in the last 90 days
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.

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.

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.

What researchers measure

Primary outcomes

  1. Mortality

    The primary outcome in this study is early mortality, defined as lesion related death or any death that occurs within 30-days post-procedure or within initial hospitalization following the index procedure (whichever occurs last), unless there is evidence of accidental or self-inflicted death

    Time frame: 30 days

Secondary outcomes

  1. Mortality

    All-cause death events will be counted

    Time frame: 12 months

  2. Major Adverse Event (MAE)

    Occurrence of at least one of the following MAEs at 30 days and 1 year post NEXUS implantation * Disabling Stroke * Permanent Paralysis/Paraplegia * Renal failure * Aortic rupture * Development of new dissections in the thoracic aorta or brachiocephalic artery

    Time frame: 30 days and 12 months

  3. Device failure

    Device Failure will be assessed via the following outcomes: * Peri-operative device failure * Device occlusion * Surgical conversion * Re-Intervention to treat migration, * Re-Intervention to treat stenosis or occlusion, * Re-Intervention to treat type Ia, Ib, III, IV endoleaks * Re-Intervention for loss of device integrity

    Time frame: Procedure, 30 days, 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 Dec 4, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
