Overview
11 DESCRIPTION KENGREAL is a direct-acting P2Y 12 platelet receptor inhibitor that blocks adenosine diphosphate (ADP)-induced platelet activation and aggregation. The chemical structure is similar to adenosine triphosphate (ATP). The chemical name of KENGREAL is tetrasodium salt of N6-[2-(methylthio)ethyl]-2-[(3,3,3,-trifluoropropyl)-5’-adenylic acid, monanhydride with (dichloromethylene)...
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Cangrelor is a direct P2Y 12 platelet receptor inhibitor that blocks ADP-induced platelet activation and aggregation. Cangrelor binds selectively and reversibly to the P2Y 12 receptor to prevent further signaling and platelet activation. 12.2 Pharmacodynamics Cangrelor inhibits activation and aggregation of platelets. After administration of a 30 mcg/kg IV bolus followed by a 4 mcg/kg/min IV infusion, platelet inhibition occurs within 2 minutes. Figure 2 shows the effect on platelet activity, and its relation to cangrelor plasma concentration, of administering a 30 mcg/kg IV bolus, followed by a 1-hour 4 mcg/kg/min IV infusion, of cangrelor. The anti-platelet effect is maintained for the duration of the infusion.
Indications
- 1 INDICATIONS AND USAGE KENGREAL is indicated as an adjunct to percutaneous coronary intervention (PCI) to reduce the risk of periprocedural myocardial infarction (MI), repeat coronary revascularization, and stent thrombosis (ST) in patients who have not been treated with a P2Y 12 platelet inhibitor and are not being given a glycoprotein IIb/IIIa inhibitor [see Clinical Studies ( 14.1 )].

Dosage
2 DOSAGE AND ADMINISTRATION KENGREAL is intended for administration via a dedicated IV line, only after reconstitution and dilution. ( 2.3 ) Administer 30 mcg/kg intravenous (IV) bolus prior to PCI followed immediately by a 4 mcg/kg/min IV infusion for at least 2 hours or duration of procedure, whichever is longer. ( 2.1 ) To maintain platelet inhibition after discontinuation of KENGREAL infusion, administer an oral P2Y 12 platelet inhibitor. ( 2.2 ) 2.1 Recommended Dosing The recommended dosage of KENGREAL is a 30 mcg/kg IV bolus followed immediately by a 4 mcg/kg/min IV infusion.

Side Effects
- 6 ADVERSE REACTIONS The following adverse reactions are also discussed elsewhere in the labeling: Bleeding [see Warnings and Precautions ( 5.1 )] The most common adverse reaction is bleeding. ( 5.1 , 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Chiesi USA, Inc. at 1-888-661-9260 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reactions rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not...
Interactions
- 7 DRUG INTERACTIONS Clopidogrel: Do not administer during KENGREAL infusion. ( 7.1 ) Prasugrel: Do not administer during KENGREAL infusion. ( 7.1 ) 7.1 Thienopyridines Clopidogrel or prasugrel administered during KENGREAL infusion will have no antiplatelet effect until the next dose is administered. Therefore, administer clopidogrel or prasugrel after KENGREAL infusion is discontinued [see Dosage and Administration ( 2.2 ) and Clinical Pharmacology ( 12.3 )]. 7.
