Brief Summary

The primary aim of this study is to determine rates of patients with optimal platelet reactivity range, defined as PRU levels between 85 and 208, when using a (PFT)-guided titration of cangrelor infusion rate (cangrelor titration) compared to 0.75 mcg/kg/min (standard-dose infusion) for bridging.

Detailed Description

The proposed investigation is a prospective, single-arm, open-label PD study in patients that are admitted to UF Health Jacksonville with established coronary artery disease. These patients will be awaiting a coronary intervention in the cardiac cath lab or a coronary artery bypass graft in the operating room and have received at least a two-hour infusion of cangrelor as standard of care for bridging at 0.75 mcg/kg/min (standard-dose infusion).The typical wait time for the patient's aforementioned procedure/surgery is 5 days or more and the study schedule will not interfere with the typical clinical processes. If the patient's procedure or surgery is re-scheduled to an earlier than expected time, then the study procedures will stop and will not delay the patient's standard of care procedure/surgery. . Patients will be recruited from the inpatient units of the institution and screened by the Cardiology Research staff, who will verify that all candidates meet the inclusion and exclusion criteria.

After providing informed consent, eligible patients will undergo a baseline evaluation of PRU levels by means of the VerifyNow system. The research study team will perform the PRU assessment in the cardiovascular research lab as this is considered a research only assessment and is not currently performed as standard of care. Patients with PRU levels ≤208 will undergo cangrelor dose reduction to 0.50 mcg/kg/min, while patients with PRU levels >208 will undergo dose increase to 1.0 mcg/kg/min. At 2 to 12 hours after dose titration, blood samples will be collected for further PD assessment of platelet reactivity. Patients with PRU values >208 will undergo dose increase by 0.25 mc/kg/min up to a maximum of 1.5 mcg/kg/min until a PRU below 208 is achieved, while patients with PRU levels <85 will undergo dose reduction to 0.25 mcg/kg/min, being the lowest possible administration rate allowed during the study period.

Blood sampling for PD testing will be performed at different time points: a) baseline (while on 0.75 mcg/kg/min before dose titration); b) between 2 and 12 hours following dose titration; c) daily (at the same time for the second dose) for up to a maximum of 3 samples after dose titration. 8 ml of blood will be obtained at each time point. Patients receiving an oral P2Y12 inhibitor after the cangrelor infusion start will not undergo further PD testing. All other medications will be prescribed as per standard-of-care prescriptions. Study participation will not interfere with standard clinical treatment or delay care. If cangrelor must be stopped per standard of care prior to study completion, then all collected data will be utilized and study participation will end. At the end of the study participation, the patients will follow the medication regimens prescribed by their treating physician per standard of care.

Study Groups

Platelet function-guided cangrelor titration

Patients with PRU levels ≤208 will undergo cangrelor dose reduction to 0.50 mcg/kg/min, while patients with PRU levels \>208 will undergo dose increase to 1.0 mcg/kg/min. At 2 to 12 hours after dose titration, blood samples will be collected for further PD assessment of platelet reactivity. Patients with PRU values \>208 will undergo dose increase by 0.25 mc/kg/min up to a maximum of 1.5 mcg/kg/min until a PRU below 208 is achieved, while patients with PRU levels \<85 will undergo dose reduction to 0.25 mcg/kg/min, being the lowest possible administration rate allowed during the study period. Titration will be performed at 3 time points: baseline (while on 0.75 mcg/kg/min before dose titration); between 2 and 12 hours following dose titration; daily (at the same time for the second dose) for up to a maximum of 3 samples after dose titration.

Group Type: EXPERIMENTAL

Cangrelor

Intervention Type: DRUG

Patients with PRU levels ≤208 will undergo cangrelor dose reduction to 0.50 mcg/kg/min, while patients with PRU levels \>208 will undergo dose increase to 1.0 mcg/kg/min. At 2 to 12 hours after dose titration, blood samples will be collected for further PD assessment of platelet reactivity. Patients with PRU values \>208 will undergo dose increase by 0.25 mc/kg/min up to a maximum of 1.5 mcg/kg/min until a PRU below 208 is achieved, while patients with PRU levels \<85 will undergo dose reduction to 0.25 mcg/kg/min, being the lowest possible administration rate allowed during the study period. Titration will be performed at 3 time points: baseline (while on 0.75 mcg/kg/min before dose titration); between 2 and 12 hours following dose titration; daily (at the same time for the second dose) for up to a maximum of 3 samples after dose titration.

Interventions

Cangrelor

Patients with PRU levels ≤208 will undergo cangrelor dose reduction to 0.50 mcg/kg/min, while patients with PRU levels \>208 will undergo dose increase to 1.0 mcg/kg/min. At 2 to 12 hours after dose titration, blood samples will be collected for further PD assessment of platelet reactivity. Patients with PRU values \>208 will undergo dose increase by 0.25 mc/kg/min up to a maximum of 1.5 mcg/kg/min until a PRU below 208 is achieved, while patients with PRU levels \<85 will undergo dose reduction to 0.25 mcg/kg/min, being the lowest possible administration rate allowed during the study period. Titration will be performed at 3 time points: baseline (while on 0.75 mcg/kg/min before dose titration); between 2 and 12 hours following dose titration; daily (at the same time for the second dose) for up to a maximum of 3 samples after dose titration.
