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
|Condition or disease||Intervention/treatment||Phase|
|Cognition Disorder Stroke Occlusion Carotid||Procedure: Endovascular intervention Drug: Maximal medical therapy||Phase 1 Phase 2|
This is a phase 2 randomized single-center open label clinical trial with randomization of 1:1 to either best medical management vs. best medical management and endovascular revascularization of COICA.
Screening, Enrolling, & Randomization:
All subjects who presents to our tertiary hospital with a diagnosis of COICA will undergo full evaluation including 1) documenting previous history of transient ischemic attack (TIA) and/or stroke; 2) cervical and brain CT angiography (CTA) to document complete occlusion; 3) CT perfusion (CTP) to assess for presence of penumbra evident by increased mean transient time (MTT) in the ipsilateral side of COICA; and 4)MontReal cognitive assessment (MoCA) score. If any subject is found to have complete occlusion of COICA, evident of abnormal/prolongation of MTT on CTP, previous history of TIA and or stroke, and MoCA <26 & ≥ 23, then further evaluation is obtained including: MRI spectroscopy to assess for presence/absence of lactate in the ipsilateral watershed area (centrum semiovale), and size of ipsilateral hippocampus and amygdala, additional cognitive testing battery, and digital subtraction angiography (DSA) to document adequately the type of COICA the subject have (type A-D).
If any subject does not have complete occlusion, or complete occlusion but no abnormalities on CTP and/or MoCA >26, then the subject is excluded and no further testing needed (see exclusion criteria).
If the subject meets all inclusion criteria, then a baseline of complete neurological testing, full demographics, CTA or MRA, CTP, MoCA, additional neurological testing, MRI spectroscopy and DSA are obtained and subject is randomized 1:1 to either best medical management or best medical management + endovascular balloon angioplasty and stenting. Follow up clinic visits are arranged at 3 and 12 months. Repeat testing of MoCA and additional cognitive testing battery are done at these clinical follow-up visits (3 and 12 months). MRI of the brain and DSA is performed at 1 year follow-up to assess brain bio-markers and revascularization respectively.

|Experimental: Endovascular arm||
Procedure: Endovascular intervention
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
|Active Comparator: Medical arm||
Drug: Maximal medical therapy
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.
- MoCA Score [ Time Frame: 12-month ]Cognitive outcome assessed by the MontReal Cognitive Assessment score
- Composite Cognitive Score [ Time Frame: 12-month ]
This is one outcome that reflects the overall cognition. The composite cognitive score at 12-month follow-up is assessed by a composite z score based on average z score for the tests for each subject (sum of the z scores divided by the number of tests included) from a specifically designed battery of 14 cognitive tests. Scores from tests in the proposed neuropsychological battery will be converted to z-scores. This is the following battery:
Montreal Cognitive Assessment (MoCA),Wide Range Achievement Test-5 (WRAT-5); Wechsler Adult Intelligence Scale - IV (WAIS-IV); WAIS-IV, Coding subtest; WAIS-IV, Matrix Reasoning subtest; Hopkins Verbal Learning Test ; Benton Visual Retention Test (BVRT) ; Controlled Oral Word Association (COWA) Test; Boston Naming Test;Boston Diagnostic Aphasia Examination, Complex Ideational Material subtest;Trail-Making Test, part A and part B; Beck Depression Inventory-Fast Screen (BDI-FS);Iowa Scales of Personality Change (ISPC).
- Stroke [ Time Frame: 12-month ]Incidence of ipsilateral stroke
- Hemorrhage [ Time Frame: 12-month ]Incidence of ipsilateral cerebral hemorrhage
- Death [ Time Frame: 12-months ]Rate death
- MTT [ Time Frame: 12-month ]Resolution/improvement of increased mean transit time (MTT) on CT perfusion. RABID software will be analyzed using a T-Test, at enrollment vs. 1 year
- Size of amygdala [ Time Frame: 12-month ]The change in size of hippocampus in the ipsilateral side of COICA (t-test), at enrollment vs. 1 year
- Size of hippocampus [ Time Frame: 12-month ]The change in size of amygdala in the ipsilateral side of COICA (t-test) at enrollment vs. 1 year
- Lactate [ Time Frame: 12-month ]Concentration of Lactate on MRI spectroscopy in centrum semiovale in the ipsilateral side of COICA at enrollment vs 1 year.
