  • Table of Contents
  • 1 INDICATIONS AND USAGE

    Tirofiban hydrochloride injection is indicated to reduce the rate of thrombotic cardiovascular events (combined endpoint of death, myocardial infarction, or refractory ischemia/repeat cardiac procedure) in patients with non-ST elevation acute coronary syndrome (NSTE-ACS).

  • 2 DOSAGE AND ADMINISTRATION

    2.1 Recommended Dosage

    The recommended dosage is 25 mcg/kg administered intravenously within 5 minutes and then 0.15 mcg/kg/min for up to 18 hours.

    2.2 Administration

    For intravenous use only. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.

    To open the 100 mL or 250 mL premixed bag, first tear off its foil overpouch. The plastic may be somewhat opaque because of moisture absorption during sterilization; the opacity will diminish gradually. Check for leaks by squeezing the inner bag firmly; if any leaks are found or sterility is suspect then the solution should be discarded. Do not use unless the solution is clear and the seal is intact.

    Administration Instructions

    1. The bolus dose of tirofiban hydrochloride injection may be administered from the 100 mL or 250 mL premixed bag. Do not dilute. Administer the bolus dose within 5 minutes via IV pump.
    2. Immediately following the bolus dose administration, administer the maintenance infusion from the 100 mL premixed bag or the 250 mL premixed bag via an IV pump.
    3. Discard any unused portion left in the bag.

    The recommended bolus volume using the 100 mL premixed bag or 250 mL premixed bag can be calculated using the following equation:

                                                                                      Bolus Volume        =          25 mcg/kg x body weight (kg)
                                                                                                (mL)                                         50 mcg/mL

    The recommended infusion rate for patients with CrCl (Creatinine Clearance) >60 mL/min using the 100 mL premixed bag or 250 mL premixed bag can be calculated using the following equation:
     


                                                                          Infusion Rate for CrCl > 60 mL/min  =  0.15 mcg/kg/min × body weight (kg) × 60 min/h
                                                                                               (mL/h)                                                            50 mcg/mL

      


    Example calculation of infusion rate for 60 kg patient with CrCl >60 mL/min using the 100 mL premixed bag or 250 mL premixed bag:


                                                                         Infusion Rate for CrCl > 60 mL/min  =  0.15 mcg/kg/min × 60 kg × 60 min/h  =  10.8 mL/h
                                                                                                  (mL/h)                                                          50 mcg/mL


    Drug Compatibilities

    Tirofiban hydrochloride injection can be administered in the same intravenous line as heparin, atropine sulfate, dobutamine, dopamine, epinephrine hydrochloride (HCl), famotidine injection, furosemide, lidocaine, midazolam HCl, morphine sulfate, nitroglycerin, potassium chloride, and propranolol HCl. Do not administer tirofiban hydrochloride injection through the same IV line as diazepam. Do not add other drugs or remove solution directly from the bag with a syringe.

    2.3 Dose Adjustment for Renal Impairment

    The recommended dosage in patients with CrCl ≤ 60 mL/min (calculated using the Cockcroft-Gault equation with actual body weight) is 25 mcg/kg intravenously within 5 minutes and then 0.075 mcg/kg/min, for up to 18 hours.


    The recommended infusion rate for patients with CrCl ≤ 60 mL/min using the 100 mL premixed bag or 250 mL premixed bag can be calculated using the following equation:

                                                                             Infusion Rate for CrCl ≤ 60 mL/min  =  0.075 mcg/kg/min × body weight (kg) × 60 min/h 
                                                                                       (mL/h)                                                       50 mcg/mL

  • 4 CONTRAINDICATIONS

    Tirofiban hydrochloride injection is contraindicated in patients with:

    • Severe hypersensitivity reaction to tirofiban hydrochloride (i.e., anaphylactic reactions) [see Adverse Reactions (6.2)].
    • A history of thrombocytopenia following prior exposure to tirofiban hydrochloride [see Adverse Reactions (6.1)].
    • Active internal bleeding or a history of bleeding diathesis, major surgical procedure or severe physical trauma within the previous month [see Adverse Reactions (6.1)].
  • 5 WARNINGS AND PRECAUTIONS

    5.1 General Risk of Bleeding

    Bleeding is the most common complication encountered during therapy with tirofiban hydrochloride. Most bleeding associated with tirofiban hydrochloride occurs at the arterial access site for cardiac catheterization. Minimize the use of traumatic or potentially traumatic procedures such as arterial and venous punctures, intramuscular injections, nasotracheal intubation, etc.


    Concomitant use of fibrinolytics, anticoagulants and antiplatelet drugs increases the risk of bleeding.

    5.2 Thrombocytopenia

    Profound thrombocytopenia has been reported with tirofiban hydrochloride. Monitor platelet counts beginning about 6 hours after treatment initiation and daily thereafter. If the platelet count decreases to < 90,000/mm3, monitor platelet counts to exclude pseudothrombocytopenia. If thrombocytopenia is confirmed, discontinue tirofiban hydrochloride and heparin. Previous exposure to a glycoprotein (GP) IIb/IIIa receptor antagonist may increase the risk of developing thrombocytopenia [see Adverse Reactions (6.1)].

  • 6 ADVERSE REACTIONS

    6.1 Clinical Trial Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction 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 clinical practice.


    In the PRISM (Platelet Receptor Inhibition for Ischemic Syndrome Management), PRISM-PLUS (Platelet Receptor Inhibition for Ischemic Syndrome Management — Patients Limited by Unstable Signs and Symptoms) and RESTORE (Randomized Efficacy Study of Tirofiban for Outcomes  and  Restenosis) trials, 1946 patients received tirofiban hydrochloride in combination with heparin and 2002 patients received tirofiban hydrochloride alone for about 3 days. Forty-three percent of the population was > 65 years of age and approximately 30% of patients were female. In clinical studies with the recommended regimen (25 mcg/kg bolus followed by a 0.15 mcg/kg/min maintenance infusion), tirofiban hydrochloride was administered in combination with aspirin, clopidogrel and heparin or bivalirudin to over 8000 patients for typically ≤ 24 hours. Approximately 30% of the population was > 65 years of age and approximately 25% were female.

    The incidence rates of TIMI major bleeding in patients undergoing coronary artery bypass graft surgery (CABG) in PRISM-PLUS within one day of discontinuation of tirofiban hydrochloride were 17% on tirofiban hydrochloride plus heparin (N=29) and 35% on heparin alone (N=31).


    Recommended (“High-Dose Bolus”) Regimen

    Rates of major bleeds (including any intracranial, intraocular or retroperitoneal hemorrhage, clinically overt signs of hemorrhage associated with a drop in hemoglobin of > 3 g/dL or any drop in hemoglobin by 4 g/dL, bleeding requiring transfusion of ≥ 2 U blood products, bleeding directly resulting in death within 7 days or hemodynamic compromise requiring intervention) were consistent with the rates observed in subjects administered the PRISM-PLUS regimen of tirofiban hydrochloride. There was a trend toward greater bleeding in ST segment elevation myocardial infarction (STEMI) patients treated with fibrinolytics prior to administration of tirofiban hydrochloride using the recommended regimen during rescue PCI.


    Non-Bleeding

    Thrombocytopenia


    Patients treated with tirofiban hydrochloride plus heparin, were more likely to experience decreases in platelet counts than were those on heparin alone. These decreases were reversible upon discontinuation of tirofiban hydrochloride. The percentage of patients with a decrease of platelets to < 90,000/mm3 was 1.5%, compared with 0.6% in the patients who received heparin alone. The percentage of patients with a decrease of platelets to < 50,000/mm3 was 0.3%, compared with 0.1% of the patients who received heparin alone.

    6.2 Post-Marketing Experience

    The following additional adverse reactions have been identified during post-approval use of tirofiban hydrochloride. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to the drug exposure.

    Hypersensitivity: Severe allergic reactions including anaphylactic reactions have occurred during the first day of tirofiban hydrochloride infusion, during initial treatment, and during readministration of tirofiban hydrochloride. Some cases have been associated with severe thrombocytopenia (platelet counts < 10,000/mm3). No information is available on the formation of antibodies to tirofiban.

  • 7 DRUG INTERACTIONS

    Concomitant use of fibrinolytics, anticoagulants and antiplatelet drugs increases the risk of bleeding.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary


    While published data cannot definitively establish the absence of risk, available published case reports have not established an association with tirofiban use during pregnancy and major birth defects, miscarriage, or adverse maternal or fetal outcomes. Untreated myocardial infarction can be fatal to the pregnant woman and fetus (see Clinical Considerations). Studies with tirofiban HCl at intravenous doses up to 5 mg/kg/day (about 5 and 13 times the maximum recommended daily human dose for rat and rabbit, respectively, when compared on a body surface area basis) have revealed no harm to the fetus.


    The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.


    Clinical Considerations


    Disease-associated maternal and/or embryo/fetal risk


    Myocardial infarction is a medical emergency in pregnancy which can be fatal to the pregnant woman and fetus if left untreated.

    8.2 Lactation

    Risk Summary


    There is no data on the presence of tirofiban in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on human milk production. However, tirofiban is present in rat milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for tirofiban hydrochloride and any potential adverse effects on the breastfed child from tirofiban hydrochloride or from the underlying maternal condition.

    8.4 Pediatric Use

    Safety and effectiveness in pediatric patients have not been established.

    8.5 Geriatric Use

    Of the total number of patients in controlled clinical studies of tirofiban hydrochloride, 43% were 65 years and over, while 12% were 75 years and over. With respect to efficacy, the effect of tirofiban hydrochloride in the elderly (≥ 65 years) appeared similar to that seen in younger patients (< 65 years). Elderly patients receiving tirofiban hydrochloride with heparin or heparin alone had a higher incidence of bleeding complications than did younger patients, but the incremental risk of bleeding in patients treated with tirofiban hydrochloride in combination with heparin compared to the risk in patients treated with heparin alone was similar regardless of age. No dose adjustment is recommended for the elderly population [see Dosage and Administration (2)].

    8.6 Renal Insufficiency

    Patients with moderate to severe renal insufficiency have decreased plasma clearance of tirofiban hydrochloride. Reduce the dosage of tirofiban hydrochloride in patients with severe renal insufficiency [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)].

    Safety and efficacy of tirofiban hydrochloride has not been established in patients on hemodialysis.

  • 10 OVERDOSAGE

    In clinical trials, inadvertent overdosage with tirofiban hydrochloride occurred in doses up to 2 times the recommended dose for initial infusion doses. Inadvertent overdosage occurred in doses up to 9.8 times the 0.15 mcg/kg/min maintenance infusion rate.


    The most frequently reported manifestation of overdosage was bleeding, primarily minor mucocutaneous bleeding events and minor bleeding at the sites of cardiac catheterization [see Warnings and Precautions (5.1)].


    Overdosage of tirofiban hydrochloride should be treated by assessment of the patient’s clinical condition and cessation or adjustment of the drug infusion as appropriate.


    Tirofiban hydrochloride can be removed by hemodialysis.

  • 11 DESCRIPTION

    Tirofiban hydrochloride injection contains tirofiban hydrochloride, a non-peptide antagonist of the platelet GP IIb/IIIa receptor, which inhibits platelet aggregation.


    Tirofiban hydrochloride monohydrate is chemically described as N-(butylsulfonyl)-O-[4-(4- piperidinyl)butyl]-L-tyrosine hydrochloride monohydrate.


    Its molecular formula is C22H36N2O5S•HCl•H2O and its structural formula is:

    chemical-structure


    Tirofiban hydrochloride monohydrate is a off-white, non-hygroscopic, free-flowing powder, with a molecular weight of 495.07. It is very slightly soluble in water.


    Tirofiban hydrochloride injection premixed is supplied as a sterile solution in water for injection, for intravenous use. The pH of the solution ranges from 5.5 to 6.5 adjusted with hydrochloric acid and/or sodium hydroxide.


    Each 100 mL of the premixed, isosmotic intravenous injection contains 5.618 mg tirofiban hydrochloride monohydrate equivalent to 5 mg tirofiban (50 mcg/mL) and the following inactive ingredients: 0.9 g sodium chloride, 54 mg sodium citrate dihydrate, and 3.2 mg citric acid anhydrous.


    Each 250 mL of the premixed, isosmotic intravenous injection contains 14.045 mg tirofiban hydrochloride monohydrate equivalent to 12.5 mg tirofiban (50 mcg/mL) and the following inactive ingredients: 2.25 g sodium chloride, 135 mg sodium citrate dihydrate, and 8 mg citric acid anhydrous.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Tirofiban hydrochloride is a reversible antagonist of fibrinogen binding to the GP IIb/IIIa receptor, the major platelet surface receptor involved in platelet aggregation. When administered intravenously, tirofiban hydrochloride inhibits ex vivo platelet aggregation in a dose- and concentration-dependent manner.


    When given according to the PRISM-PLUS regimen of 0.4 mcg/kg/min over 30 minutes followed by a 0.1 mcg/kg/min maintenance infusion, > 90% inhibition of platelet aggregation is attained by the end of the 30-minute infusion. When given according to the recommended regimen of 25 mcg/kg followed by a 0.15 mcg/kg/min maintenance infusion, > 90% inhibition of platelet aggregation is attained within 10 minutes. Platelet aggregation inhibition is reversible following cessation of the infusion of tirofiban hydrochloride.

    12.2 Pharmacodynamics

    Tirofiban hydrochloride inhibits platelet function, as demonstrated by its ability to inhibit ex vivo adenosine phosphate (ADP)-induced platelet aggregation and prolong bleeding time in healthy subjects and patients with coronary artery disease. The time course of inhibition parallels the plasma concentration profile of the drug.


    Following discontinuation of an infusion of tirofiban hydrochloride 0.10 mcg/kg/min, ex vivo platelet aggregation returns to near baseline in 4 to 8 hours in approximately 90% of patients with coronary artery disease. The addition of heparin to this regimen does not significantly alter the percentage of subjects with > 70% inhibition of platelet aggregation (IPA), but does increase the average bleeding time, as well as the number of patients with bleeding times prolonged to > 30 minutes. Similar platelet aggregation recovery rates are observed following discontinuation of a 0.15 mcg/kg/min infusion.

    12.3 Pharmacokinetics

    Tirofiban has a half-life of approximately 2 hours. It is cleared from the plasma largely by renal excretion, with about 65% of an administered dose appearing in urine and about 25% in feces, both largely as unchanged tirofiban. Metabolism appears to be limited.


    Tirofiban is not highly bound to plasma proteins and protein binding is concentration independent over the range of 0.01 to 25 mcg/mL. The unbound fraction in human plasma is 35%. The steady state volume of distribution of tirofiban ranges from 22 to 42 liters.


    In healthy subjects, the plasma clearance of tirofiban ranges from 213 to 314 mL/min. Renal clearance accounts for 39 to 69% of plasma clearance.

    Specific Populations  


    There is no effect on clearance of tirofiban by sex, race, age, or hepatic impairment.


    Renal Insufficiency

    Plasma clearance of tirofiban is decreased about 40% in subjects with creatinine clearance < 60 mL/min and > 50% in patients with creatinine clearance < 30 mL/min, including patients requiring hemodialysis [see Dosage and Administration (2.3)]. Tirofiban is removed by hemodialysis.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    The carcinogenic potential of tirofiban hydrochloride has not been evaluated.


    Tirofiban HCl was negative in the in vitro microbial mutagenesis and V-79 mammalian cell mutagenesis assays. In addition, there was no evidence of direct genotoxicity in the in vitro alkaline elution and in vitro chromosomal aberration assays. There was no induction of chromosomal aberrations in bone marrow cells of male mice after the administration of intravenous doses up to 5 mg tirofiban/kg (about 3 times the maximum recommended daily human dose when compared on a body surface area basis).


    Fertility and reproductive performance were not affected in studies with male and female rats given intravenous doses of tirofiban up to 5 mg/kg/day (about 5 times the maximum recommended daily human dose when compared on a body surface area basis).

  • 14 CLINICAL STUDIES

    Two large-scale clinical studies established the efficacy of tirofiban hydrochloride in the treatment of patients with NSTE-ACS (unstable angina/non-ST elevation MI). The two studies examined tirofiban hydrochloride alone and added to heparin, prior to and after percutaneous coronary revascularization (if indicated) (PRISM-PLUS) and in comparison to heparin in a similar population (PRISM). These trials are discussed in detail below.


    PRISM-PLUS (Platelet Receptor Inhibition for Ischemic Syndrome Management — Patients Limited by Unstable Signs and Symptoms)


    In the double-blind PRISM-PLUS trial, 1570 patients with documented NSTE-ACS within 12 hours of entry into the study were randomized to tirofiban hydrochloride (30 minute initial infusion of 0.4 mcg/kg/min followed by a maintenance infusion of 0.10 mcg/kg/min) in combination with heparin (bolus of 5,000 U followed by an infusion of 1,000 U/h titrated to maintain an activated partial thromboplastin time (APTT) of approximately 2 times control) or to heparin alone. All patients received concomitant aspirin unless contraindicated. Patients who were medically managed or who underwent revascularization procedures were studied. Patients underwent 48 hours of medical stabilization on study drug therapy, and they were to undergo angiography before 96 hours (and, if indicated, angioplasty/atherectomy, while continuing on tirofiban hydrochloride and heparin for 12 to 24 hours after the procedure). Tirofiban hydrochloride and heparin could be continued for up to 108 hours. Exclusions included contraindications to anticoagulation, decompensated heart failure, platelet count < 150,000/mm3, and serum creatinine > 2.5 mg/dL. The mean age of the population was 63 years; 32% of patients were female and approximately half of the population presented with non-ST elevation myocardial infarction. On average, patients received tirofiban hydrochloride for 71 hours.


    A third group of patients was initially randomized to tirofiban hydrochloride alone (no heparin). This arm was stopped when the group was found, at an interim look, to have greater mortality than the other two groups.


    The primary endpoint of the study was a composite of refractory ischemia, new MI and death within 7 days. There was a 32% risk reduction in the overall composite primary endpoint. The components of the composite were examined separately and the results are shown in Table 6. Note that the sum of the individual components may be greater than the composite (if a patient experiences multiple component events only one event counts towards the composite).

    The benefit seen at 7 days was maintained over time. The risk reduction in the composite endpoint at 30 days and 6 months is shown in the Kaplan-Meier curve below.

    An analysis of the results by sex suggests that women who are medically managed or who undergo subsequent percutaneous transluminal coronary angioplasty (PTCA)/atherectomy may receive less benefit from tirofiban hydrochloride (95% confidence limits for relative risk of 0.61 to 1.74) than do men (0.43 to 0.89) (p=0.11). This difference may be a true treatment difference, the effect of other differences in these subgroups, or a chance occurrence.


    Approximately 90% of patients in the PRISM-PLUS study underwent coronary angiography and 30% underwent angioplasty/atherectomy during the first 30 days of the study. The majority of these patients continued on study drug throughout these procedures. Tirofiban hydrochloride was continued for 12 to 24 hours (average 15 hours) after angioplasty/atherectomy. The effects of tirofiban hydrochloride at Day 30 did not appear to differ among sub-populations that did or did not receive PTCA or CABG, both prior to and after the procedure.


    PRISM (Platelet Receptor Inhibition for Ischemic Syndrome Management)


    In the PRISM study, a randomized, parallel, double-blind study, 3232 patients with NSTE-ACS intended to be managed without coronary intervention were randomized to tirofiban hydrochloride (initial dose of 0.6 mcg/kg/min for 30 minutes followed by 0.15 mcg/kg/min for 47.5 hours) or heparin (5,000-unit intravenous bolus followed by an infusion of 1,000 U/h for 48 hours). The mean age of the population was 62 years; 32% of the population was female and 25% had non-ST elevation MI on presentation. Thirty percent had no ECG evidence of cardiac ischemia. Exclusion criteria were similar to PRISM-PLUS. The primary endpoint was the composite endpoint of refractory ischemia, MI or death at the end of the 48-hour drug infusion. The results are shown in Table 7.

    In the PRISM study, no adverse effect of tirofiban hydrochloride on mortality at either 7 or 30 days was detected. This result is different from that in the PRISM-PLUS study, where the arm that included tirofiban hydrochloride without heparin (N=345) was dropped at an interim analysis by the Data Safety Monitoring Committee for increased mortality at 7 days.
