Abstract
To compare the effect of cilostazol plus aspirin versus aspirin alone on the progression of intracranial arterial stenosis (IAS), and to compare ischemic and hemorrhagic events in patients with symptomatic IAS, an investigator-driven, nationwide multicenter cooperative randomized controlled trial (CATHARSIS; ClinicalTrials.gov Identifier 00333164) was conducted. 165 noncardioembolic ischemic stroke patients with >50% stenosis in the responsible intracranial artery after 2 weeks to 6 months from the onset were randomly allocated to receive either cilostazol 200 mg/day plus aspirin 100 mg/day (n = 83, CA group) or aspirin 100 mg/day alone (n = 82, A group). The primary endpoint was the progression of IAS on magnetic resonance angiography at 2 years after randomization. Secondary endpoints were any vascular events, any cause of death, serious adverse events, new silent brain infarcts, and worsening of the modified Rankin Scale score. Progression of IAS was observed in 9.6% of the CA group patients and in 5.6% of the A group patients, with no significant intergroup difference (p = 0.53). The incidence of the secondary endpoints tended to be lower in the CA group compared with the A group, although the differences were not significa...Continue Reading
