  • 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 P2Y12 platelet inhibitor and are not being given a glycoprotein IIb/IIIa inhibitor [see Clinical Studies (14.1)].

    Close
  • 2 DOSAGE AND ADMINISTRATION

    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. 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.

    2.2       Transitioning Patients to Oral P2Y12 Therapy

    To maintain platelet inhibition after discontinuation of KENGREAL infusion, an oral P2Y12 platelet inhibitor should be administered. Administer one as described below:

    • Ticagrelor: 180 mg at any time during KENGREAL infusion or immediately after discontinuation [see Clinical Pharmacology (12.2)].
    • Prasugrel: 60 mg immediately after discontinuation of KENGREAL. Do not administer prasugrel prior to discontinuation of KENGREAL [see Drug Interactions (7.1) and Clinical Pharmacology (12.2)].
    • Clopidogrel: 600 mg immediately after discontinuation of KENGREAL. Do not administer clopidogrel prior to discontinuation of KENGREAL [see Drug Interactions (7.1) and Clinical Pharmacology (12.2)].

    2.3       Preparation and Administration

    KENGREAL is intended for IV administration, after reconstitution and dilution.

    Preparation

    For each 50 mg/vial, reconstitute by adding 5 mL of Sterile Water for Injection. Swirl gently until all material is dissolved. Avoid vigorous mixing. Allow any foam to settle. Ensure that the contents of the vial are fully dissolved and the reconstituted material is a clear, colorless to pale yellow solution. Reconstitute the vial prior to dilution in a bag. Parenteral drug products should be inspected visually for particulate matter after reconstitution.

    Do not use without dilution. Before administration, each reconstituted vial must be diluted further with Normal Saline (Sodium Chloride Injection 0.9% USP) or 5% Dextrose Injection USP.

    Withdraw the contents from one reconstituted vial and add to one 250 mL saline bag. Mix the bag thoroughly. This dilution will result in a concentration of 200 mcg/mL and should be sufficient for at least 2 hours of dosing. Patients 100 kg and over will require a minimum of 2 bags.

    Reconstituted KENGREAL should be diluted immediately. Diluted KENGREAL is stable for up to 12 hours in 5% Dextrose Injection and 24 hours in Normal Saline at Room Temperature. Discard any unused portion of reconstituted solution remaining in the vial.

    Administration

    Administer KENGREAL via a dedicated IV line.

    Administer the bolus volume rapidly (<1 minute), from the diluted bag via manual IV push or pump. Ensure the bolus is completely administered before the start of PCI. Start the infusion immediately after administration of the bolus [see Dosage and Administration (2.1)].

  • 5 WARNINGS AND PRECAUTIONS

    5.1       Bleeding

    Drugs that inhibit platelet P2Y12 function, including KENGREAL, increase the risk of bleeding.

    In CHAMPION PHOENIX bleeding events of all severities were more common with KENGREAL than with clopidogrel [see Adverse Reactions (6.1)]. Bleeding complications with KENGREAL were consistent across a variety of clinically important subgroups (see Figure 1).

    Once KENGREAL is discontinued, there is no antiplatelet effect after an hour [see Clinical Pharmacology (12.3)].

  • 6 ADVERSE REACTIONS

    The following adverse reactions are also discussed elsewhere in the labeling:

    • Bleeding [see Warnings and Precautions (5.1)]

    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 reflect the rates observed in practice.

    The safety of KENGREAL has been evaluated in 13,301 subjects in controlled trials, in whom, 5,529 were in the CHAMPION PHOENIX trial.

    Bleeding

    There was a greater incidence of bleeding with KENGREAL than with clopidogrel. No baseline demographic factor altered the relative risk of bleeding with KENGREAL (see Table 1 and Figure 1).

Apparent homogeneity or heterogeneity among groups should not be over-interpreted.

    Drug Discontinuation

    In CHAMPION PHOENIX the rate of discontinuation for bleeding events was 0.3% for KENGREAL and 0.1% for clopidogrel. Discontinuation for non-bleeding adverse events was low and similar for KENGREAL (0.6%) and for clopidogrel (0.4%). Coronary artery dissection, coronary artery perforation, and dyspnea were the most frequent events leading to discontinuation in patients treated with KENGREAL.

    Non-Bleeding Adverse Reactions

    Hypersensitivity

    Serious cases of hypersensitivity were more frequent with KENGREAL (7/13301) than with control (2/12861). These included anaphylactic reactions, anaphylactic shock, bronchospasm, angioedema, and stridor.

    Decreased renal function

    Worsening renal function was reported in 3.2% of KENGREAL patients with severe renal impairment (creatinine clearance <30 mL/min) compared to 1.4% of clopidogrel patients with severe renal impairment.

    Dyspnea

    Dyspnea was reported more frequently in patients treated with KENGREAL (1.3%) than with control (0.4%).

  • 7 DRUG INTERACTIONS

    7.1       Thienopyridines

    If clopidogrel or prasugrel are administered during KENGREAL infusion, they will have no antiplatelet effect until the next dose is administered. Clopidogrel and prasugrel, therefore, should not be administered until KENGREAL infusion is discontinued [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3)].

  • 8 USE IN SPECIFIC POPULATIONS

    8.1       Pregnancy

    Pregnancy Category C

    There are no adequate and well-controlled studies of KENGREAL in pregnant women.

    Cangrelor did not produce malformations in either the rat or rabbit reproductive studies, and is not considered to be a teratogen.

    In embryo-fetal development studies in rats, cangrelor produced dose-related fetal growth retardation characterized by increased incidences of incomplete ossification and unossified hind limb metatarsals at plasma concentration of approximately 5 times lower than that achieved in the PCI setting at the maximum recommended human dose (MRHD). In rabbits, cangrelor was associated with increased incidences of abortion and intrauterine losses, as well as fetal growth retardation at plasma concentrations of approximately 12 times higher than the PCI setting at the MRHD.

    8.3       Nursing Mothers

    It is not known whether KENGREAL is excreted in human milk.

    8.4       Pediatric Use

    Safety and effectiveness in pediatric patients have not been established.

    8.5       Geriatric Use

    In CHAMPION PHOENIX, 18% of patients were ≥75 years. No overall differences in safety or effectiveness were observed between these patients and those patients <75 years [see Clinical Studies (14.1)].

    8.6       Renal Impairment

    No dosage adjustment is required for patients with mild, moderate, or severe renal impairment [see Clinical Pharmacology (12.3)].

    8.7       Hepatic Impairment

    KENGREAL has not been studied in patients with hepatic impairment. However, the metabolism of KENGREAL is not dependent of hepatic function, so that dosage adjustment is not required for patients with hepatic impairment [see Clinical Pharmacology (12.3)].

  • 10 OVERDOSAGE

    There is no specific treatment to reverse the antiplatelet effect of KENGREAL but the effect is gone within one hour after the drug is discontinued.

    In clinical trials, 36 patients received an overdose of KENGREAL, ranging from 36 to 300 mcg/kg (bolus dose) or 4.8 to 13.7 mcg/kg/min (infusion dose). The maximum overdose received was 10 times the PCI bolus dose or 3.5 times the PCI infusion dose in 4 patients. No clinical sequela were noted as a result of overdose following completion of KENGREAL therapy.

  • 12 CLINICAL PHARMACOLOGY

    12.1       Mechanism of Action

    Cangrelor is a direct P2Y12 platelet receptor inhibitor that blocks ADP-induced platelet activation and aggregation. Cangrelor binds selectively and reversibly to the P2Y12 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. After discontinuation of the infusion, the anti-platelet effect decreases rapidly and platelet function returns to normal within 1 hour.

    Figure 2: Cangrelor PD Characteristics

    Figure 2: Cangrelor PD Characteristics

    12.3       Pharmacokinetics

    KENGREAL administered intravenously has linear pharmacokinetics in both healthy volunteers and patients. KENGREAL is rapidly distributed and metabolized, reaching Cmax within 2 minutes after administration of an intravenous bolus followed by infusion.

    Distribution

    In a study in healthy volunteers, KENGREAL administration at a dose of 30 mcg/kg bolus plus 4 mcg/kg/min showed a volume of distribution of 3.9 L. Plasma protein binding of KENGREAL is about 97-98%.

    Metabolism

    KENGREAL is deactivated rapidly in the circulation by dephosphorylation to its primary metabolite, a nucleoside, which has negligible anti-platelet activity. KENGREAL’s metabolism is independent of hepatic function and it does not interfere with other drugs metabolized by hepatic enzymes.

    Elimination

    Following IV administration of [3H] KENGREAL 58% of radioactivity was recovered in urine. The remaining 35% of radioactivity was in feces, presumably following biliary excretion. The average elimination half-life of KENGREAL is about 3-6 minutes.

    Specific Populations

    KENGREAL pharmacokinetics are not affected by sex, age, renal status or hepatic function. No dose adjustment is needed for these factors [see Use in Specific Populations (8)].

    Weight

    Although weight was a significant covariate for PK with higher clearance in heavier patients, the impact of weight on drug exposure is accounted by the use of weight-based dosing.

    Drug-Drug Interactions

    Co-administration of cangrelor with unfractionated heparin, aspirin, and nitroglycerin was formally studied in healthy subjects, with no evidence of an effect on the PK/PD of cangrelor.

    In clinical trials cangrelor has been co-administered with bivalirudin, low molecular weight heparin, clopidogrel, prasugrel, and ticagrelor without clinically detectable interactions.

    The expected antiplatelet effect of a 600 mg loading dose of clopidogrel or a 60 mg loading dose of prasugrel was blocked when clopidogrel or prasugrel was administered during a cangrelor infusion [see Drug Interactions (7.1)].

    In contrast, the antiplatelet effect of a 180 mg ticagrelor loading dose was not altered significantly when ticagrelor was administered during cangrelor infusion [see Drug Interactions (7.1)].

    Figure 3: Inhibition (Mean) of 20 µM ADP-induced Platelet Aggregation (IPA) Measured by Light Transmission Aggregometry after Cangrelor 30 mcg/kg Bolus and 120-minute 4 mcg/kg Infusion with Transition to Other Oral P2Y12 Platelet Inhibitors.

    Figure 3: Inhibition (Mean) of 20 µM ADP-induced Platelet Aggregation (IPA) Measured by Light Transmission Aggregometry after Cangrelor 30 mcg/kg Bolus and 120-minute 4 mcg/kg Infusion with Transition to Other Oral P2Y12 Platelet Inhibitors.

    As shown in Figure 3, discontinuation of cangrelor infusion, followed by administration of the irreversible P2Y12 platelet inhibitors clopidogrel and prasugrel led to a 1-hour decrease in IPA followed by an increase in inhibition of platelet aggregation beginning at about one hour. This time course of platelet inhibition reflects the pharmacokinetics of cangrelor (offset) followed by the absorption and metabolism of clopidogrel and prasugrel to active metabolites (onset). Administration of ticagrelor, a reversible P2Y12 platelet inhibitor, during the cangrelor infusion led to minimal decrease in platelet inhibition for approximately 0.5 hours following discontinuation of the cangrelor infusion. Administering ticagrelor during cangrelor infusion does not attenuate the anti-platelet effect of ticagrelor.

    In vitro studies suggest that neither cangrelor nor its major metabolites inhibit the activity of the hepatic CYP isoenzymes at therapeutic concentrations. Therefore, cangrelor administration is not expected to interfere with the hepatic metabolism of other concomitantly administered therapeutic agents.

  • 13 NONCLINICAL TOXICOLOGY

    13.1       Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenesis

    No carcinogenicity studies were conducted.

    Mutagenesis

    Cangrelor was non-mutagenic and non-clastogenic in genetic toxicology studies, including in vitro bacterial gene mutation assay, mouse lymphoma thymidine kinase assay, chromosome aberration assay in human peripheral lymphocytes, and in vivo bone marrow micronucleus assay in mice.

    Impairment of Fertility

    Cangrelor had no significant effect on male or female rats fertility treated for 28 days, or on early embryonic development at steady state plasma concentration (Css) of approximately the same as that achieved in the PCI setting at the MRHD.

  • 14 CLINICAL STUDIES

    14.1       CHAMPION PHOENIX Trial

    The CHAMPION PHOENIX trial was intended to test whether faster platelet inhibition with cangrelor at the time of PCI would reduce the rate of periprocedural thrombotic events compared to a drug with a slower antiplatelet effect, clopidogrel, given at about the time of PCI. It was a randomized, double-blind study in which patients with coronary artery disease (stable angina, UA/NSTEMI, STEMI) requiring PCI and receiving standard therapy including aspirin and heparin or bivalirudin were randomized 1:1 to KENGREAL (n=5472) or to clopidogrel 300 or 600 mg (n=5470). Patients who had already taken an oral P2Y12 platelet inhibitor were not eligible to enroll. Patients administered glycoprotein IIb/IIIa inhibitors (GPI) or for whom GPI use was planned were also not eligible to enroll. PHOENIX was thus a study of people undergoing PCI who had not been previously treated with anti-platelet therapy other than aspirin.

    The primary outcome measure was the first occurrence of any one of the composite endpoint of all-cause mortality, myocardial infarction (MI), ischemia-driven revascularization (IDR), and stent thrombosis (ST) within 48 hours after randomization.

    KENGREAL was administered as 30 mcg/kg bolus followed by 4 mcg/kg/min infusion for 2 to 4 hours. Clopidogrel 600 mg was administered immediately at the end of the KENGREAL infusion in patients randomized to KENGREAL. Clopidogrel 300 mg or 600 mg was administered shortly before PCI or shortly afterward, in patients randomized to clopidogrel.

    KENGREAL significantly reduced the occurrence of primary composite endpoint events compared to clopidogrel (relative risk reduction [RRR] 22%). Most of the effect was a reduction in post-procedural MIs detected solely by elevations in CK-MB (type 4a MI). KENGREAL did not reduce the risk of death. Table 2 shows the study results for the primary composite endpoint and the contribution of each component to the primary endpoint.
