A Multicentre, Single-Arm Clinical Study to Evaluate the Efficacy and Safety of Flow Diverters (PFMD-001) for Cerebral Aneurysms
Basic Information
Recruitment status | Recruiting |
---|---|
Health condition(s) or Problem(s) studied | cerebral aneurysm |
Date of first enrollment | 24/06/2024 |
Target sample size | 130 |
Countries of recruitment | |
Study type | Interventional |
Intervention(s) | Deliver therapeutic equipment to lesions using unapproved devices during cerebrovascular treatment. |
Outcome(s)
Primary Outcome | Efficacy: Complete occlusion of the treated aneurysm and patency of the parent artery at 12 months post-treatment angiography, with no additional treatment of the treated aneurysm in the 12-month post-operative period. Safety: No severe stroke or neurological deaths attributable to treatment or the device within 12 months of treatment. |
---|---|
Secondary Outcome | (1) Technical success of treatment (implantation of the device in a position that covers the area of cerebral aneurysm to be treated). (2) Procedural success of treatment (technical success without serious adverse events or equipment failure due to treatment or procedure). (3) Occlusion of the treated aneurysm after 12 months of treatment (4) Patency of the parent artery after 12 months of treatment (no stenosis or occlusion >50%) (5) Re-treatment within 12 months after treatment. (6) All causes of mortality within 30 days and until 12 months of treatment. (7) Neurological deaths within 30 days and at 12 months of treatment. (8) All strokes within 30 days and until 12 months of treatment. (9) Stroke in the treated vasculature within 30 days and until 12 months of treatment. (10) Severe stroke in the treated vasculature within 30 days and until 12 months of treatment. (11) Serious adverse events within 30 days and until 12 months of treatment. (12) Adverse events (classification and aggregation by neurological and non-neurological systems) and equipment failure. |
