Long-Term Sequential Dual Antiplatelet Therapy Based on Cilostazol in Symptomatic Intracranial Arterial Stenosis (SPDACSIS-RCT)
The Secondary Preventive Effect of Long-term Sequential Dual Antiplatelet Therapy Based on Cilostazol in Cerebral Infarction Patients With Symptomatic Moderate to Severe Intracranial Arterial Stenosis: A Single-Center, Randomized, Open-Label, Blinded-Endpoint Clinical Trial (SPDACSIS-RCT)
This study aims to evaluate whether long-term dual antiplatelet therapy (DAPT) with cilostazol reduces the risk of recurrent symptomatic ischemic stroke or all-cause mortality compared with single antiplatelet therapy (SAPT) in patients with symptomatic moderate-to-severe intracranial arterial stenosis, following the completion of standard DAPT.

Yksityiskohtainen kuvaus
Patients with symptomatic intracranial arterial stenosis remain at high risk of recurrent stroke despite standard medical treatment. Although short-term DAPT is recommended, the optimal long-term antiplatelet strategy following standard treatment remains uncertain. Cilostazol-based DAPT may provide additional protection against recurrent ischemic events with an acceptable bleeding risk. Therefore, this study aims to evaluate whether long-term cilostazol-based DAPT reduces the risk of recurrent symptomatic ischemic stroke or all-cause mortality compared to SAPT in patients with symptomatic moderate-to-severe intracranial arterial stenosis.
