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.
Panoramica dello studio
Stato
Intervento / Trattamento
Descrizione dettagliata
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.

Sperimentale: Cilostazol-Based Dual Antiplatelet Therapy
Participants will receive cilostazol 50 mg twice daily in combination with one antiplatelet agent: aspirin 100 mg once daily, clopidogrel 75 mg once daily, or ticagrelor 90 mg twice daily, for 12 months. |
Cilostazol 50 mg twice daily for 12 months. Cilostazol is administered in the experimental arm in combination with one antiplatelet agent: aspirin, clopidogrel, or ticagrelor. Aspirin 100 mg once daily for 12 months. Aspirin may be administered in combination with cilostazol in the experimental arm or as single antiplatelet therapy in the active comparator arm. Clopidogrel 75 mg once daily for 12 months. Clopidogrel may be administered in combination with cilostazol in the experimental arm or as single antiplatelet therapy in the active comparator arm. Ticagrelor 90 mg twice daily for 12 months. Ticagrelor may be administered in combination with cilostazol in the experimental arm or as single antiplatelet therapy in the active comparator arm. |

Aspirin 100 mg once daily for 12 months. Aspirin may be administered in combination with cilostazol in the experimental arm or as single antiplatelet therapy in the active comparator arm. Clopidogrel 75 mg once daily for 12 months. Clopidogrel may be administered in combination with cilostazol in the experimental arm or as single antiplatelet therapy in the active comparator arm. Ticagrelor 90 mg twice daily for 12 months. Ticagrelor may be administered in combination with cilostazol in the experimental arm or as single antiplatelet therapy in the active comparator arm. |
