About this study

A prospective clinical evaluation of the effectiveness of the Ovation Alto Abdominal Stent Graft System when used in the treatment of subjects with abdominal aortic aneurysm (AAA).

Read the detailed description

A prospective clinical evaluation of the effectiveness of the Ovation Alto Abdominal Stent Graft System when used in the treatment of subjects with abdominal aortic aneurysm (AAA). The primary objective is to evaluate treatment success at 12 months with the Ovation Alto Abdominal Stent Graft system. The study will have up to 16 sites, and up to 75 patients based on attrition rates. The follow-up intervals will be at 1, 6, and 12 months following initial implant procedure.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Subjects With Treatment Success

    Treatment success is defined as technical success, freedom from type I and III endoleaks at 12 months, freedom from stent graft migration > 10m at 12 months compared to 1 month baseline, freedom from AAA enlargement >5mm at 12 months (compared to 1-month baseline, freedom from AAA rupture through 12 months, freedom from conversion to open repair through 12 months, stent graft stenosis, occlusion or kink requiring secondary intervention through 12 months, thromboembolic event attributable to stent graft requiring secondary intervention through 12 months, stent fracture requiring secondary intervention through 12 months.

    Measured: 12 months

Secondary outcomes (14)
  1. Event Rates for Endoleaks

    Endoleak is defined by the persistence of blood flow outside the lumen of the endovascular graft but within the aneurysm sac and can be classified as:

    • Type I - Ineffective seal at either the proximal or distal sealing zones
    • Type IA - Ineffective seal at the proximal sealing zone
    • Type IB - Ineffective seal at the distal sealing zone
    • Type II - Retrograde blood flow from lumbar arteries, the inferior mesenteric artery, or other collateral vessels into the aneurysm sac
    • Type III - A leak caused by fabric tears or disruption, component disconnection, or graft disintegration
    • Type IIIA - Junctional leak or component disconnection
    • Type IIIB - Midgraft hole
    • Type IV - Blood flow through an intact fabric.
    • Unknown endoleak - Endoleak present but unable to assess type Endoleak will only be evaluated as an adverse event or serious adverse event if it is present at the 30-day follow-up visit or if a post-index procedure re-intervention occurs.

    Measured: 1 month, 6 months, 12 months

  2. Number of Participants With Stent Graft Migration > 10mm

    any change of stent graft migration (movement) greater than 10mm

    Measured: 6 months, 12 months

  3. Number of Participants With AAA Enlargement > 5mm

    Change in aneurysm diameter greater than 5mm

    Measured: 6 months, 12 months

  4. Number of Participants With AAA Rupture

    A tear in the abdominal aorta that can result in serious internal bleeding.

    Measured: 30 day, Day 31-365

  5. Number of Participants With Conversion to Open Repair

    conversion to open abdominal surgery to repair AAA

    Measured: 30 day, Day 31-365

  6. Number of Secondary Interventions

    Intervention occurring after index procedure and having to do with device or AAA.

    Measured: 30 days, Day 31-365

  7. Number of Participants With AAA-related Mortality

    death caused by or related to AAA

    Measured: 1 month, Day 31-365

  8. Device-related Adverse Events (AEs)

    Device-Related: Event is caused or contributed by any component of the device during delivery, deployment or while the device is in situ post-operatively

    Measured: 30 days, Day 31-365

  9. Major Adverse Events

    Major adverse events (MAE) are defined as any one of the following events:

    • Death
    • Myocardial Infarction
    • Stroke (excludes TIA)
    • Renal Failure (excludes renal insufficiency)
    • Respiratory Failure (excludes chronic obstructive pulmonary disease (COPD) or pulmonary complications)
    • Paralysis (excludes paraparesis)
    • Bowel Ischemia
    • Procedural Blood Loss (≥1,000 cc)

    Measured: 1 year

  10. Number of Participants With Other Stent Graft Finding (Includes Kinking and Stent Compression)

    The integrity of the stent graft is evaluated by the Independent Core Lab via abdominal X-rays at regularly scheduled follow-up visits. Any fractured stents, and any other issues compromising the integrity of the stent graft will be reported.

    Measured: 1 month, 6 months, 12 months

  11. Number of Participants With Stent Fracture

    The integrity of the stent graft is evaluated by the Independent Core Lab via abdominal X-rays at regularly scheduled follow-up visits. Any fractured stents, and any other issues compromising the integrity of the stent graft will be reported.

    Measured: 1 month, 6 months, 12 months

  12. Adverse Events (Serious and Non-serious)

    An adverse event is any new, undesirable medical occurrence or change (worsening) of a pre-existing condition that occurs in a subject, whether or not considered to be associated with the product

    Measured: 30 days, Day 31-365

  13. Procedure-related Adverse Event

    Procedure-Related event is caused or contributed by the initial study device implantation (index) procedure, up to 30 days, unless a different etiology can be identified

    Measured: 30 days, Day 31-365

  14. Serious Adverse Event

    A serious adverse event (SAE) defined as one that suggests a significant hazard or side effect, regardless of the investigator or Sponsor's opinion on the relationship to the investigational product. This includes, but may not be limited to, any event that:

    • Is fatal
    • Is life-threatening
    • Requires or prolongs (>48 hours) inpatient hospitalization
    • Is a persistent or significant disability or incapacity
    • Is considered an important medical event

    Measured: 30 Days, Day31-365)

Questions about this trial

What is this clinical trial studying?

A study testing Ovation Alto Abdominal Stent Graft System in people with Aortic Aneurysm, Abdominal, run by Endologix at 13 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Subjects With Treatment Success (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02949297, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
