About this study

Official title: A Post-Market Surveillance Clinical Registry of the TREOVANCE® Stent-Graft for Patients With Infrarenal Abdominal Aortic Aneurysms

Patients with abdominal aortic aneurysms (AAA) suitable for endovascular aortic repair (EVAR) with Treovance were eligible to participate. Main inclusion criteria were: age 18-85 years; infrarenal AAA without significant infrarenal or distal iliac landing neck calcification or thrombus formation; infrarenal or distal iliac landing neck size requirements specified in the instructions for use. Main exclusion criteria: dissection/ruptured aneurysm or prior AAA endovascular or surgical repair. The primary endpoints were standard EVAR criteria.

Read the detailed description

The goal of the registry was to collect clinical data of TREOVANCE® device in subjects with infrarenal aortic aneurysms, specifically to evaluate if the diseased pathology is treated with an acceptable technical success rate, an acceptable complication rate and that the device performs as expected.

The following endovascular measures/parameters were assessed for preliminary performance at the follow-up intervals: delivery/deployment, stent-graft migration, stent-graft patency, stent-graft integrity, endoleak, aneurysm sac size changes, limb ischemia, and vascular access complications.

This registry was a prospective, multi-center, post-market non-randomized study. The goal was to gather safety and performance data on the device. Subjects diagnosed with infrarenal aortic aneurysms enrolled into the registry were treated with the TREOVANCE® Stent-Graft with Navitel® Delivery System. Pre-procedure baseline data was gathered as well as post-procedure assessments prior to hospital discharge and 1, 6, and 12 months post-implantation.

What is being measured

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

  4. Rate of Stent-Graft Integrity

    Device effectiveness will be measured by the rate of Stent-Graft Integrity observed

    Measured: 1 month, 6 months and 12 months

  5. Rate of Endoleaks

    Device effectiveness will be measured by the rate of Endoleaks reported

    Measured: 1 month, 6 months and 12 months

  6. Rate of Aneurysm Sac Size Changes

    Device effectiveness will be measured by the rate of Aneurysm Sac Size Changes at 6 months and 12 months as compared to the first post-procedure imaging

    Measured: 6 months and 12 months

  7. Rate of Limb Ischemia

    Device effectiveness will be measured by the rate of Limb Ischemia resulting in limb loss

    Measured: 1 month, 6 months and 12 months

  8. Rate of Vascular Access Complications

    Device effectiveness will be measured by the rate of Vascular Access Complications

    Measured: 1 month, 6 months and 12 months

  9. Rate of unintentional covering of renal arteries and / or hypogastric arteries

    Device effectiveness will be measured by the rate of unintentional covering of renal arteries and / or hypogastric arteries during the index procedure

    Measured: Procedure / Study Day 0

Questions about this trial

What is this clinical trial studying?

An observational study of Abdominal Aortic Aneurysm, run by Bolton Medical at 32 sites in 17 countries.

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 12 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 32 sites in Spain, Germany, Italy, United Kingdom, Chile and 12 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 reporting Major Adverse Events (time frame: Through 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 NCT03449875, which also lists 2 linked publications.

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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jun 2020.
