Condition(s) targeted: Chronic Kidney Disease; Stable Angina

Intervention: Clopidogrel, cilostazol (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Kyunghee University Medical Center

Weon Kim, MD, PhD, Principal Investigator, Affiliation: Kyung Hee University


Impaired renal function is associated with reduced responsiveness to clopidogrel. There are no studies which have shown a means by which to overcome platelet hyporesponsiveness in patients with chronic kidney disease (CKD). The purpose of this study was to determine the functional impact of cilostazol in patients with CKD undergoing hemodialysis.

Clinical Details

Official title: Platelet Reactivity in Patients With Chronic Kidney Disease Receiving Adjunctive Cilostazol Compared to a High-maintenance Dose of Clopidogrel

Study design: Allocation: Randomized, Endpoint Classification: Bio-availability Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Treatment

Primary outcome: The differences of platelet aggregation according to the anti-platelet therapy.

Secondary outcome: Changes of platelet activation markers according to the anti-platelet therapy

Detailed description: The aims of this study is to evaluate the effects of platelet responsiveness to clopidogrel or cilostazol in CKD patients undergoing hemodialysis. The differences in platelet activation markers are also evaluated before and after clopidogrel or cilostazol administration. The investigators will perform a prospective, randomized study to compare the degree of platelet inhibition and platelet activation markers by adjunctive cilostazol (100 mg twice daily) compared to clopidogrel (75 or 150 mg/day) in CKD patients undergoing hemodialysis.
