Read the detailed description
This is a multi-center observational study. Treatment and follow-up visits will be done as per standard of care.
The purpose of this study is to demonstrate that use of the FRED/FRED Jr Embolic device in intracranial aneurysm treatment is safe and effective when assessed at 1, 6 and 12 month post procedure.
100 patients will be enrolled over an 18-month recruitment period. All patients will be followed for 12 months.

Questions about this trial
What is this clinical trial studying?
An observational study of Intracranial Aneurysm, run by Microvention-Terumo, Inc. at 7 sites in United Kingdom.
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 8 inclusion and 15 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 29 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in United Kingdom. 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?
Complete aneurysm occlusion without ˃ 50% parent artery stenosis (time frame: 6 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 29 Apr 2022; AzTrials last refreshed its copy on 8 Nov 2026.
