Comparing cilostazol and aspirin for preventing stroke in patients with cerebral microbleeds

Official title: The Efficacy and Safety of Cilostazol Compared to Aspirin in Acute Non-Cardioembolic Stroke Patients With Concurrent Cerebral Microbleeds: An Open-Label, Endpoint-Blinded, Randomized Non-Inferiority Clinical Trial

Run by Zhejiang Provincial People's Hospital · NCT06530537 · Data updated 2026-11-12

This study is testing if a medication called cilostazol can prevent strokes as effectively as aspirin in patients who have had a stroke and also have small bleeding spots in the brain.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals who have had an acute non-cardioembolic ischemic stroke within the past month and have confirmed cerebral microbleeds.

Probably not a fit

Patients with a history of cerebral amyloid angiopathy or those requiring combined anticoagulant therapy may not benefit from this study.

What this trial studies

This clinical trial aims to evaluate the efficacy and safety of cilostazol compared to aspirin for the secondary prevention of stroke in patients who have experienced an acute non-cardioembolic ischemic stroke and have concurrent cerebral microbleeds. Participants will be randomly assigned to receive either cilostazol or aspirin, with their health monitored through baseline and follow-up assessments at various intervals over four years. The primary focus will be on stroke recurrence, while secondary endpoints will include other vascular events and safety assessments related to bleeding. The study seeks to determine if cilostazol is non-inferior to aspirin in this specific patient population.

Why it matters

Potential benefit: If successful, this study could provide an alternative treatment option for patients at risk of stroke with cerebral microbleeds.

How similar studies have gone: While the specific comparison of cilostazol and aspirin in this context may be novel, similar studies have explored antiplatelet therapies in stroke prevention with varying degrees of success.
