Brief Summary

Patients with diabetes mellitus (DM) are at increased risk of atherothrombotic events. Importantly, DM is a key risk factor for the development of chronic kidney disease (CKD), which further enhances atherothrombotic risk. Clopidogrel is the most widely used platelet P2Y12 receptor inhibitor. However, despite its clinical benefit, patients with DM and CKD frequently experience recurrent atherothrombotic events. Ticagrelor is an oral, reversible, non-competitive P2Y12 receptor inhibitor with more potent and consistent platelet inhibition than clopidogrel. In large-scale clinical investigation, ticagrelor significantly reduced ischemic events to a greater extent than clopidogrel, a finding that was consistent also among DM patients. To date there has been no analysis on the efficacy of ticagrelor in DM patients according to CKD status. Moreover, although pharmacodynamic (PD) studies showed enhanced platelet inhibition associated with ticagrelor, it is unknown how this may be affected by CKD status. Ultimately, how PK/PD profiles of different ticagrelor dosing regimens may be affected by DM and CKD status is also unknown. The proposed study is aimed to show the impact of CKD status among patients with DM and coronary artery disease) CAD on PD and PK profiles of ticagrelor used at 2 doses (90mg bid and 60mg bid) in the setting of a prospective, randomized, cross-over trial.

Detailed Description

Patients with diabetes mellitus (DM) are at increased risk of atherothrombotic events. Importantly, DM is a key risk factor for the development of chronic kidney disease (CKD), which further enhances atherothrombotic risk. These observations underscore the importance of antiplatelet therapy for prevention of atherothrombotic recurrences in these high-risk patients. Clopidogrel is the most widely used platelet P2Y12 receptor inhibitor. However, despite its clinical benefit, patients with DM and CKD frequently experience recurrent atherothrombotic events. This may be in part due to the impaired pharmacokinetic (PK) and pharmacodynamic (PD) effects of clopidogrel in patients with DM and CKD. Since both DM and CKD represent pandemic public health problems, the prevalence of which will double over the next 20 years, identifying antiplatelet agents with more favorable PK/PD profiles is of key importance.

Ticagrelor is an oral, reversible, non-competitive P2Y12 receptor inhibitor with more potent and consistent platelet inhibition than clopidogrel. In large-scale clinical investigation, ticagrelor significantly reduced ischemic events to a greater extent than clopidogrel, a finding that was consistent also among DM patients. In patients with CKD, ticagrelor led to an even greater relative risk reduction of ischemic events, including cardiovascular mortality, compared to patients without CKD. However, to date there has been no analysis on the efficacy of ticagrelor in DM patients according to CKD status. Moreover, although PD studies showed enhanced platelet inhibition associated with ticagrelor, it is unknown how this may be affected by CKD status. Ultimately, how PK/PD profiles of different ticagrelor dosing regimens may be affected by DM and CKD status is also unknown. The proposed study is aimed to show the impact of CKD status among patients with DM and CAD on PD and PK profiles of ticagrelor used at 2 doses (90mg bid and 60mg bid) in the setting of a prospective, randomized, cross-over trial.
