Study information
Scientific title
A prospective, non-randomised, open-label, multicenter safety study of Neucrylate AN™ Liquid Embolic System for the treatment of cerebral berry aneurysms
Acronym
Study hypothesis
The primary objectives of this safety study are to assess the efficacy and composite safety-and-efficacy of Neucrylate AN™ Liquid Embolic System for the treatment of cerebral aneurysms. The secondary objectives assess other features of the treatment, including the incidence of all AEs, an assessment of the passage of unwanted device into the arterial lumen, the user acceptability of the device, the success of delivery, need for retreatment, and neurologic deterioration.

Condition
Berry aneurysms in the brain
Intervention
The treatment being studied is the Neucrylate AN™ Liquid Embolic System, which is a liquid that is placed into the aneurysm via angiography catheters. There is no comparator. There are follow-up visits at 6 weeks and at 5 months following hospital discharge. All hospital visits and all follow-up visits include neurological assessments and adverse events/serious adverse events (AE/SAE) collection. The 6-month visit includes brain imaging (computed tomography angiography [CTA], magnetic resonance imaging [MRI]) or catheter angiography to assess the aneurysm.

Primary outcome measures
1. Neurological assessments will be done using the Glasgow Coma Scale, Hunt and Hess Scale, and Modified Rankin Score. These will be done at Screening, Procedure Day, Post-procedure Day 1, Hospital Discharge, Week 6, and at the Month 6 Visit.
2. Aneurysm filling will be assessed using the following scale on Procedure Day and at the Month 6 Visit:
i. 0 - 24% filling
ii. 25 - 49% filling
iii. 50 - 74% filling
iv. 75 - 89% filling
v. 90% filling or more
3. Major Adverse Events (MAEs): During the implant procedure and for the 6-month follow-up period, all of the deaths, major strokes (resulting in a Modified Rankin score of >=3), and haemorrhages from the treated aneurysm will be documented.
Secondary outcome measures
1. Adverse Events (AEs) and Serious Adverse Events (SAEs): During the implant procedure and for the 6-month follow-up period, all of the adverse events and serious adverse events will be documented. The investigator will provide his/her opinion, based on clinical experience and judgment, on the relationship between the event and either: (a) the procedure done to implant Neucrylate™, or (b) the presence of the Neucrylate™ in the body.
2. Unwanted device: Unwanted passage of device beyond the aneurysm in the parent vessel, or prior to reaching the aneurysm, on a 6-point scale:
i. No device in brain arteries noted
ii. Device in brain arteries that compromise <=25% of the arterial lumen
iii. Device in brain arteries that compromise 26-50% of the arterial lumen
iv. Device in brain arteries that compromise 51-75% of the arterial lumen
v. Device in brain arteries that compromise >=75% of the arterial lumen
vi. Device completely occludes arterial lumen
3. User acceptability: For all three user acceptability measures (1) visibility of material, (2) ease of introduction, and (3) ease of delivery, assessments will be recorded.
