About this study
Official title: a Prospective, Multi-center, Open-label, Non-inferiority, Randomized, Controlled Registration Trial of the Intracranial Stent for the Treatment of Intracranial Aneurysms: Rebridge
This trial was designed as a prospective, multicentre, open, non-inferiority, randomised controlled clinical trial, with the control devices being MicroVention's LVIS Intraluminal Support Device and LVIS Jr. Intraluminal Support Device. Approximately 200 subjects with intracranial aneurysms would be enrolled for stent-assisted coiling embolisation according to the inclusion and exclusion criteria specified in this trial protocol. Subjects were evaluated by mRS preoperatively, at the time of device implantation, at the time of discharge from the hospital, at 1 month (±7 days) postoperatively, at 6 months (±30 days) postoperatively, and at 12 months (±60 days) postoperatively; subjects would underwent DSA imaging at surgery and at 6 months (±30 days) postoperatively, and MRA or DSA imaging at 12 months (±60 days) postoperatively. Unplanned follow-up of the subjects would performed when necessary, and data would be recorded to evaluate the safety and efficacy of intracranial artery stent for stent-assisted coiling embolisation for the treatment of intracranial aneurysms.

What is being measured
The primary outcome is the main question the study is designed to answer.
Rate of aneurysms with adequate occlusion
The Raymond-Roy intracranial aneurysm occlusion classification was used to assess the rate of aneurysm occlusion postoperatively or at the time of primary endpoint assessment (12 months). Occlusion rates were reported as Class I: complete occlusion; Class II: residual neck; Class III: residual aneurysm.
Adequate occlusion rate includes Class I and Class II
Measured: 6 months
Secondary outcomes (6)
Rate of stent technical success
Technical successwas defined as the stent was successfully released at the appropriate position, and covered the aneurysm's neck completely while the parent artery remained unobstructed postoperatively.
Measured: immediately after the procedure
Rate of aneurysms with complete occlusion
The Raymond-Roy intracranial aneurysm occlusion classification was used to assess the rate of aneurysm occlusion postoperatively or at the time of primary endpoint assessment (12 months). Occlusion rates were reported as Class I: complete occlusion; Class II: residual neck; Class III: residual aneurysm.
Complete occlusion rate includes Class I
Measured: 6 months
Rate of in-stent stenosis (≥50%)
Measured: 6 months
Rate of aneurysms with adequate occlusion
Measured: 1 year
Rate of aneurysms with complete occlusion
Measured: 1 year
Rate of aneurysms with retreatment

This trial was designed as a prospective, multicentre, open, non-inferiority, randomised controlled clinical trial, with the control devices being MicroVention's LVIS Intraluminal Support Device and LVIS Jr. Intraluminal Support Device. Approximately 200 subjects with intracranial aneurysms would be enrolled for stent-assisted coiling embolisation according to the inclusion and exclusion criteria specified in this trial protocol. Subjects were evaluated by mRS preoperatively, at the time of device implantation, at the time of discharge from the hospital, at 1 month (±7 days) postoperatively, at 6 months (±30 days) postoperatively, and at 12 months (±60 days) postoperatively; subjects would underwent DSA imaging at surgery and at 6 months (±30 days) postoperatively, and MRA or DSA imaging at 12 months (±60 days) postoperatively. Unplanned follow-up of the subjects would performed when necessary, and data would be recorded to evaluate the safety and efficacy of intracranial artery stent for stent-assisted coiling embolisation for the treatment of intracranial aneurysms.

What does the primary outcome measure?
Rate of aneurysms with adequate occlusion (time frame: 6 months). 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 5 Jan 2024.
