In Vitro Pharmacodynamic Effects of Cangrelor on Platelet P2Y12 Receptor Mediated Signaling in Ticagrelor Treated Patients
In Brief
A clinical study evaluating Ticagrelor 180mg and Ticagrelor 90mg for Coronary Artery Disease. Completed, enrolled 60 participants across 1 site.
Detailed Summary
Cangrelor is a potent intravenous P2Y12 receptor inhibitor with rapid onset and offset of action associated with a greater reduction in ischemic events, including stent thrombosis, in patients undergoing stent procedures who have not been pretreated with clopidogrel. In vitro investigations have shown cangrelor to be associated with more rapid, potent, and consistent platelet inhibition in patients on maintenance prasugrel therapy exposed to a re-loading dose of prasugrel. However, if cangrelor exerts similar effects in ticagrelor treated patients remain unknown. The aim of the present study is to evaluate the effects on platelet function achieved after in vitro incubation with cangrelor in patients on ticagrelor maintenance dose who receive a loading dose of ticagrelor.

Timeline
Interventions
The proposed study will have a prospective, randomized, parallel design in which patients on chronic ticagrelor therapy will be assigned to receive a reloading dose of 90 or 180 mg ticagrelor. Platelet function assays will be done following in vitro incubation with and without 500 nM cangrelor.
