Genotype and Platelet Reactivity in Patients on Hemodialysis

Chronic Kidney Disease Clinical Trial

Official title:
The Relationship Between Genotype and Platelet Reactivity in Patients Treated With Ticagrelor Versus Clopidogrel: PIANO Genotype Study

Clinical Trial Summary

Patients with end stage renal disease (ESRD) on hemodialysis (HD) exhibited higher platelet reactivity to clopidogrel than did those with normal renal function. We recently reported platelet inhibition by ticagrelor was faster and markedly greater than by clopidogrel with onset dosing regimen in patients with ESRD on HD. However, few studies have been conducted genetic influence in high platelet reactivity in patients with ESRD on HD.

Clinical Trial Description

Chronic kidney disease (CKD) is a strong risk factor for cardiovascular morbidity and mortality, and confers an increasing risk of stent thrombosis even when dual antiplatelet therapy (clopidogrel and aspirin) is administered. Patients with severe CKD or end stage renal disease (ESRD) on hemodialysis (HD) exhibited higher platelet reactivity to clopidogrel than did those with normal renal function. We recently reported platelet inhibition by ticagrelor was markedly greater than by clopidogrel in patients with ESRD on HD. But exact mechanism of high platelet reactivity in ESRD patients was not fully evaluated. A possible postulation would be genetic influence. To investigate this issue, we will evaluate genetic polymorphism in patients with normal kidney function and ESRD on HD according to different doses of clopidogrel and ticagrelor. Genetic test will be assessed polymorphism of ABCB1, PON1, CYP2C19, CYP2C9 and P2Y12. ;
