EASYII - E-tegra Stent Graft System - Imaging Cohort (EASYII)

April 29, 2025 updated by: JOTEC GmbH

EASYII - A Post-Market Clinical Follow-up Study (PMCF) in Patients With Infrarenal Aortic Aneurysm Undergoing Endovascular Stenting With the E-tegra Stent Graft System - Imaging Cohort

The objective of the study is to assess the stent stability and durability as well as the seal of the stent graft during the cardiac cycle and over time as well as to evaluate safety and clinical performance of the E-tegra Stent Graft System used in endovascular treatment of infrarenal aortic aneurysm.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In this study, patients will be observed who are treated with an aorto-iliac bifurcated or aorto-uni-iliac configuration of the E-tegra Stent Graft System for the treatment of an infrarenal aortic or aorto-iliac aneurysm. The E-tegra Stent Graft components will be implanted at the discretion of the treating physician according to the local protocols.

EASYII is an interventional, non-randomized, post-market, multicentre study. The EASYII study is conducted to further assess, within the scope of the intended purpose, the E-tegra Stent Graft, including the study specific additional exam (visit at 6 months). The patients will undergo ECG-gated CTA scans instead of static CTA scans at pre-operative planning, prior to discharge, 30 days, 6 months, 12 months in order to assess the stent stability and durability as well as the seal of the stent graft during the cardiac cycle and over time. An additional ECG-gated CTA scan may optionally be performed at 24 months if the stent fixation (barbs) and stent graft conformability continue up to the 12 months scan.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
