Neurocognitive Impairment Assessment in Symptomatic Carotid Occlusion Recanalized Endovascularly

Duke University·interventional·Posted Jan 7, 2020·Updated May 9, 2025

In Brief

A Phase 2 clinical trial evaluating Endovascular intervention and Aspirin and Clopidogrel (maximal medical Therapy) for Cognition Disorder and 2 related conditions. Completed, enrolled 25 participants across 2 sites.

Detailed Summary

Complete occlusion of the Internal carotid artery (ICA) by atherosclerotic disease (COICA) causes approximately 15%-25% of ischemic strokes in the carotid artery distribution. Patients treated with medical therapy have a 7%-10% risk of recurrent stroke per year for any stroke and a 5%-8% risk per year for ipsilateral ischemic stroke during the first 2 years after ICA occlusion. Internal carotid artery occlusion causes an estimated 61,000 first-ever strokes per year in the US an incidence more than twice the annual occurrence of ruptured intracranial aneurysms Additionally, 40% of subjects with COICA who present with transient ischemic attack (TIA) and 70% of COICA who present with stroke have cognitive decline with increased risk of vascular dementia and Alzheimer's' disease (AD) with time (2,3). Symptomatic COICA subjects are at increased risk of developing cognitive impairment and progressive development of vascular dementia and AD with time. Our proposal leverages several compelling retrospective and prospective preliminary data from human to perform this exploratory trial with go/no-go criteria to proceed to a phase 3 based on the data generated

Interventions

Endovascular interventionprocedure

Endovascular angioplasty of the occluded carotid using balloon angioplasty and reconstruction with stents: coronary stents distally (Rebel, Boston Scientific; Vision, Abbott Vascular) and carotid stents proximal (Acculink and Xcat, Abbott Vascular) Patients will stay on their aspirin 325 mg and clopidogrel 75 mg

Aspirin and Clopidogrel (maximal medical Therapy)drug

Best Medical Management: daily dual antiplatelet therapy (aspirin: 325 mg p.o. qd and Clopidogrel: 75 mg p.o. qd), optimization of systolic blood pressure (120 -140 mmHg), and smoking cessation.
