COmparison of the Pharmacodynamics and Pharmacokinetics Ticagrelor Versus Clopidogrel in Patients With CKD and NSTE-ACS

Summary

Ticagrelor, a new P2Y12 receptor antagonist, achieve faster, consistent and higher platelet inhibition than clopidogrel, which was considered more noticeable in patients with ACS combining chronic kidney disease(CKD). Nonetheless, the pharmacokinetic properties of ticagrelor in the patients with CKD and NSTE-ACS has not been thoroughly studied. This study was designed to provide PK and PD data of ticagrelor compared with clopidogrel, in order to estimate that ticagrelor is superior to clopidogrel in getting better inhibition of platelet in patients with CKD and NSTE-ACS. P2Y12 inhibitor naïve patients with CKD (eGFR \< 60 ml/min/1.73m2 ) and NSTE-ACS will be enrolled in this single-center, prospective, randomized, parallel-control study and randomly assigned in a one-to-one ratio to receive ticagrelor or clopidogrel on top of chronic aspirin treatment. The primary endpoint was the PRU by Verify Now at 30 days after loading dose.
