Kengrexal is the first and only intravenous P2Y12 inhibitor providing rapid platelet inhibition during high-risk PCI-cases1-3
Kengrexal is the only parenteral P2Y12 inhibitor:
• Onset within 2 minutes1,2 • Offset within 1 hour after discontinuation1,2 • Average elimination half-life of 3–6 minutes1,2
Indication: Kengrexal, co-administered with acetylsalicylic acid (ASA), is indicated for the reduction of thrombotic cardiovascular events in adult patients with coronary artery disease undergoing percutaneous coronary intervention (PCI) who have not received an oral P2Y12 inhibitor prior to the PCI procedure and in whom oral therapy with P2Y12 inhibitors is not feasible or desirable.1
How Kengrexal works
Kengrexal is the first and only intravenous P2Y12 inhibitor.1 Kengrexal is a direct P2Y12 platelet receptor inhibitor that blocks ADP-induced platelet activation and aggregation. It binds selectively and reversibly to the P2Y12 receptor to prevent further signaling and platelet activation.
Rapid onset within 2 minutes1,2 Rapid onset of platelet inhibition within 2 minutes:
Rapid offset within 1 hour1,2 Reversible, with rapid offset and return of platelet function within 1 hour after discontinuation:
Patients who need CABG or surgery after PCI can proceed soon after Kengrexal discontinuation.
Average elimination half-life of 3–6 minutes.
Metabolism independent of organ function.
Consistent pharmacokinetics1 Not influenced by:
Blood levels of Kengrexal (green line/PK), and platelet activity (purple line/PD) with administration of a 30 mcg/kg IV bolus followed by a 4 mcg/kg/min IV infusion.2. (Graph shows a combination of fig. 1 and fig. 2 in ref 2, and is modified by Chiesi)
Administration and dosing1
Kengrexal is supplied as a sterile, lyophilized powder in 10 mL single-use vials, each containing 50 mg. It must be administered as a bolus dose followed by intravenous infusion.
Reconstitution and dilution should be prepared with an antiseptic technique. Bolus and infusion—always taken from the diluted bag.
Reconstitute Reconstitute the contents of the vial immediately before dilution.
Add 5 mL of sterile water for injection to one 50 mg vial.
Swirl gently until all material is dissolved; avoid vigorous mixing.
Allow any foam to settle.
Reconstituted Kengrexal will be a clear, colorless to pale yellow solution. Product should not contain particulate matter.
Dilute Prior to administration, each reconstituted vial must be further diluted. Dilution can be in either 0,9 % sodium chloride solution for injection or 5 % glucose solution for injection.
Withdraw the contents of a reconstituted vial and add 250 mL of sodium chloride 9 mg/mL (0,9 %) solution for injection or glucose solution (5 %) for injection.
Mix carefully. Ensure that the contents of the vial are fully dissolved and the reconstituted material is a clear, colorless to pale yellow solution. Parenteral drug products should be inspected visually for particulate matter after reconstitution
After dilution, 1 mL of solution contains 200 micrograms of Kengrexal.
Patients weighing 100 kg or more need at least two vials in two bags. Diluted Kengrexal is stable at room temperature for up to 12 hours in 5 % dextrose injection and 24 hours in normal saline. Discard any unused portion of reconstituted solution remaining in the vial.
Administration of bolus dose and intravenous infusion for PCI-procedure
Kengrexal should be administered as an intravenous bolus dose immediately followed by an intravenous infusion. The bolus and infusion should be administered from the infusion solution. The recommended dosage of Kengrexal is a 30 mcg/kg IV bolus followed immediately by a 4 mcg/kg/min IV infusion. Initiate the bolus infusion prior to PCI. The maintenance infusion should ordinarily be continued for at least 2 hours or for the duration of PCI, whichever is longer.
The dosage of Kengrexal, bolus and infusion, is based on the patient’s body weight. The dose of Kengrexal is not affected by gender, age, kidney, or liver status. See the dosing table for PCI. (länk till adminfoldern för de olika länderna)
Kengrexal should not be mixed with other medicines. Following administration of Kengrexal chronic treatment with P2Y12 inhibitors should be initiated.

Clinical documentation and safety
CHAMPION PHOENIX phase III trial efficacy results1,4 As an adjunct to PCI, Kengrexal significantly reduced the primary composite endpoint events of death, myocardial infarction, ischemia-driven revascularization, and stent thrombosis at 48 hours vs clopidogrel in an all-comer PCI patient population.1
CHAMPION PHOENIX study design4 CHAMPION PHOENIX was a randomized, double-blind, placebo-controlled, phase III trial in 11,145 patients who were undergoing either urgent or elective PCI and were receiving guideline-recommended therapy. Patients received a bolus and infusion of Kengrexal or a loading dose of 600 mg or 300 mg of clopidogrel.4
Kengrexal showed significant reductions in periprocedural thrombotic complications compared to clopidogrel1,4
CHAMPION PHOENIX primary composite endpoint—MACE (death, MI, IDR, stent thrombosis at 48 hours):Kengrexal vs clopidogrel in an all-comer PCI cohort1,4
Patients receiving Kengrexal had no statistically significant increase in either GUSTO-defined severe bleeding or need for transfusion.1,4
Major Bleeding Events (Non-CABG-related) at 48 Hours.
GUSTO = Global Use of Strategies to Open occluded Arteries; CABG = Coronary Artery Bypass Grafting.
* In CHAMPION PHOENIX, GUSTO Mild was defined as other bleeding requiring intervention but not requiring blood transfusion or causing haemodynamic compromise.
Important safety information1
Kengrexal for injection is contraindicated in patients with:
Significant active bleeding or risk of impaired hemostasis.
History of stroke or transient ischemic attack (TIA).
Known hypersensitivity (e.g., anaphylaxis) to cangrelor or any component of the product.1
The most common adverse reaction is bleeding.1,4
Treatment with Kengrexal may increase the risk of dyspnoea. The severity of most dyspnoea events was mild or moderate and transient.1,4
Here you can take part of three recorded patient cases with Kengrexal, produced in collaboration with chief physician and interventional cardiologist Per Grimfjärd, MD, PhD at Region Västmanland, Sweden.
Patient case 1: Atypical presentation STEMI – unclear diagnosis at presentation Patient with sudden loss of consciousness at home
Patient case 2: STEMI patient with nausea/vomiting Patient with repeated vomiting.
Patient case 3: STEMI presenting to Emergency Department Patient with chest pain to emergency department within 1 hour of symptom onset
