About this study

Official title: Multi-centre, Observational, Post-market, Real World Registry to Assess Outcomes of Patients Treated With the Gore® EXCLUDER® ILIAC BRANCH Endoprosthesis

This post market registry consists of a retrospective and a prospective part. The first part is a retrospective registry of all implanted IBE devices of Gore in the Netherlands after CE mark was obtained, to get an initial insight on the feasibility and safety of this procedure. The second part is to prospectively register all data on implanted IBE Gore devices, in order to gain more robust data on the efficacy of the device in maintaining hypogastric artery patency.

Read the detailed description

Rationale: The Gore IBE device is a newly designed iliac branched device, that is used in combination with the widely accepted C3 Excluder endograft for the exclusion of common iliac aneurysms and aorto-iliac aneurysms. The later has a proven safety and efficacy in excluding abdominal aortic aneurysms. The Gore IBE device got CE mark on October 2013. Technical and clinical data at short and long terms are still to be collected to give insight into technical success rates, patency data and long term follow-up.

Objective and design: This investigator-initiated post market registry consists of a retrospective and a prospective part. The first part is a retrospective registry of all implanted IBE devices of Gore in the Netherlands after CE mark was obtained, to get an initial insight on the feasibility and safety of this procedure. The second part is to prospectively register all data on implanted IBE Gore devices, in order to gain more robust data on the efficacy of the device in maintaining hypogastric artery patency.

Study population: All patients in whom a Gore IBE was or will be implanted. In the retrospective part of the study all implantations in the Netherlands will be gathered, whereas the prospective part will be expanded in Europe.

Main study parameters/endpoints: Aneurysm exclusion and reinterventions will be end-points of this study. As safety and feasibility is the main outcome of the retrospective part, the data will be analyzed at 30-days. Patients in the prospective study will be followed for 5 years, with the primary end-point being hypogastric side branch patency at 1-year. Clinical endpoints include freedom from symptoms of pelvic ischemia (buttock claudication, impotence and bowel ischemia) and freedom from aneurysm rupture.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Since this is a registry study, no burden or risk exist for the patient. There is also no direct benefit for the participating patients, but the gathered data will improve insight for patients with the same disease and might improve health care in the future for this group of patients.

Questions about this trial

What is this clinical trial studying?

An observational study of Abdominal Aortic Aneurysms and Common Iliac Aneurysms, run by Rijnstate Hospital at 8 sites in 4 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 3 inclusion and 10 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 5 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in Italy, Netherlands, Spain, New Zealand. 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?

Safety and feasibility of the IBE device (time frame: Procedure and up to 30 days post procedure). The study lists 2 primary outcomes in all. 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 NCT02345005, which also lists 25 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 5 Jan 2026.
