Phase 2
Completed
Conditions
Ischemic Stroke (exclude cardiac cerebral embolism)
Registration Number
JPRN-jRCT2080221011
Lead Sponsor
DAIICHISANKYO Co.,Ltd.
Brief Summary

In patients with non-cardioembolic stroke, who switched from treatment with clopidogrel 75 mg, 4 week CS-747S treatment provided equivalent antiplatelet effects at 2.5 mg and greater effects at 3.75 mg. By CYP2C19 phenotypes, the antiplatelet effects of CS-747S were greater at 3.75 mg in IMs and PMs, and at 2.5 mg in PMs compared with clopidogrel 75 mg. CYP2C19 polymorphisms did not affect the plasma concentration of the active metabolite of CS-747S or its antiplatelet effects, compared to clopidogrel.
