Pharmacodynamic and Pharmacokinetic Profiles of Switching Between Cangrelor and Ticagrelor Following Ticagrelor Pre-treatment: The Switching Antiplatelet -5 (SWAP-5) Study
In Brief
A Phase 4 clinical trial evaluating Cangrelor and Placebo for Coronary Artery Disease. Completed, enrolled 22 participants across 1 site.
Detailed Summary
Cangrelor is an intravenous P2Y12 inhibitor utilized as a bridge to achieve adequate platelet inhibition until oral P2Y12 inhibitors achieve their full antiplatelet effects in patients undergoing coronary stenting. Although in this setting the potent oral P2Y12 inhibitor ticagrelor is commonly utilized, there is very limited data on the optimal approach for switching between these therapies. The methodological approach for this assessment should rely on comprehensive pharmacodynamics (PD) investigations aimed to assess levels of P2Y12 receptor inhibition, pharmacokinetic (PK) investigations to assess systemic levels of the drug/drug metabolite, and mechanistic investigations by assessment of levels of P2Y12 receptor gene expression. The overarching aim of this investigation is to rule out a drug-drug interaction when ticagrelor is administered prior to cangrelor infusion.

Timeline
Interventions
Cangrelor will be used at the FDA recommended dose using a 30 μg/kg bolus followed by 4 μg/kg/min infusion. The duration of cangrelor/placebo infusion will be 2 hours. After completing the first phase of the study, patients will undergo a 1-4 week wash-out period and then will cross-over to the alternative treatment in the second phase
