ECISBI Trial Summary

This trial will test whether the drug clopidogrel can decrease the rate of new silent brain infarctions, which are linked to an increased risk for subsequent stroke and cognitive decline.

Who is the study for?
This trial is for individuals who've had a stroke or transient ischemic attack (TIA) within the last month, have initial MRI scans available, and are not on antiplatelet therapy. They must be willing to participate for two years and need secondary prevention with antiplatelet therapy as decided by their doctor. People with dementia, recent anticoagulant use, allergy to clopidogrel, certain bleeding conditions or severe kidney disease cannot join.Check my eligibility
What is being tested?
The study tests if Clopidogrel can reduce new silent brain infarctions in patients at risk of strokes due to high coated-platelet levels. It compares the effectiveness of Clopidogrel against Aspirin treatment over a period of 24 months.See study design
What are the potential side effects?
Clopidogrel may cause bleeding problems, allergic reactions, headaches, dizziness, gastrointestinal discomfort or liver enzyme changes. Aspirin might lead to stomach upset/pain, heartburn or increased risk of bleeding.

ECISBI Trial Design

2Treatment groups
Experimental Treatment
Group I: ClopidogrelExperimental Treatment1 Intervention
After randomization, patients will receive clopidogrel mg daily for the duration of the study. The VA Research Pharmacy will dispense similar looking pills (using a "dummy pill") with Arm 2 to ensure the double-blind nature of the intervention. Clopidogrel is FDA approved for secondary prevention of stroke. Patients will be followed for 24 months with repeat brain MRI scans obtained at 24 months.
Group II: AspirinExperimental Treatment1 Intervention
After randomization, patients will receive aspirin daily for the duration of the study. The VA Research Pharmacy will dispense similar looking pills (using a "dummy pill") with Arm 1 to ensure the double-blind nature of the intervention. Aspirin is FDA approved for secondary prevention of stroke. Patients will be followed for 24 months with repeat brain MRI scans obtained at 24 months.
