Impact of Timing of Pharmacodynamic Assessments on Measures of Platelet Reactivity in Patients Undergoing Percutaneous Coronary Intervention Treated With Cangrelor

This study is assessing the impact of timing of PD assessments on measures of platelet reactivity in patients undergoing PCI treated with cangrelor.

Study Overview

Status

Completed

Detailed Description

Cangrelor is characterized by reversible binding to the P2Y12 receptor and is promptly inactivated through dephosphorylation by ectonucleotidase leading to its very short plasma half-life. Consequently the timing at which PD assessments are performed after blood sample collection may impact measures of platelet reactivity in patients treated with cangrelor. We therefore hypothesize that measures of platelet inhibitory effects observed in cangrelor treated patients will reduce with time following blood sampling.
