Advisory information

contraindications
4 CONTRAINDICATIONS AGGRASTAT is contraindicated in patients with: Severe hypersensitivity reaction to AGGRASTAT (i.e., anaphylactic reactions) [see Adverse Reactions (6.2)]. A history of thrombocytopenia following prior exposure to AGGRASTAT [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)]. Known hypersensitivity to any component of AGGRASTAT. (4) History of thrombocytopenia with prior exposure to AGGRASTAT. (4) Active internal bleeding, or history of bleeding diathesis, major surgical procedure or severe physical trauma within the previous month. (4)
Adverse reactions
6 ADVERSE REACTIONS Bleeding is the most commonly reported adverse reaction. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Medicure at 1-800-509-0544 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 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 AGGRASTAT in combination with heparin and 2002 patients received AGGRASTAT 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), AGGRASTAT 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. Bleeding PRISM-PLUS Regimen The incidences of major and minor bleeding using the TIMI criteria in the PRISM-PLUS study are shown below. Table 2 TIMI Major and Minor Bleeding in PRISM-PLUS PRISM-PLUS (NSTE-ACS) Bleeding (TIMI Criteria)Major = Hemoglobin drop of >5.0 g/dL with or without an identified site, intracranial hemorrhage, or cardiac tamponade. Minor = Hemoglobin drop of >3.0 g/dL with bleeding from a known site, spontaneous gross hematuria, hematemesis or hemoptysis. AGGRASTAT0.4 mcg/kg/min initial infusion; 0.10 mcg/kg/min maintenance infusion.+ Heparin (n=773) Heparin alone (n=797) Major Bleeding 1.4% 0.8% Minor Bleeding 10.5% 8.0% Transfusions 4.0% 2.8% The incidence rates of TIMI major bleeding in patients undergoing percutaneous procedures in PRISM-PLUS are shown below. Table 3 TIMI Major Bleeding Associated with Percutaneous Procedures in PRISM-PLUS AGGRASTAT + Heparin Heparin alone N % N % Prior to Procedures 773 0.3 797 0.1 Following Angiography 697 1.3 708 0.7 Following PTCA 239 2.5 236 2.2 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 AGGRASTAT were 17% on AGGRASTAT 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 4g/dL, bleeding requiring transfusion of ≥2U 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 AGGRASTAT. There was a trend toward greater bleeding in ST segment elevation myocardial infarction (STEMI) patients treated with fibrinolytics prior to administration of AGGRASTAT using the recommended regimen during rescue PCI. Non-Bleeding The incidences of non-bleeding adverse events that occurred at an incidence of >1% and numerically higher than control, regardless of drug relationship, are shown below: Table 4 Non-bleeding Adverse Reactions in PRISM-PLUS AGGRASTAT + Heparin (N=1953) % Heparin alone (N=1887) % Body as a Whole Edema/swelling 2 1 Pain, pelvic 6 5 Reaction, vasovagal 2 1 Cardiovascular System Bradycardia 4 3 Dissection, coronary artery 5 4 Musculoskeletal System Pain, leg 3 2 Nervous System/Psychiatric Dizziness 3 2 Skin and Skin Appendage Sweating 2 1 Thrombocytopenia Patients treated with AGGRASTAT plus heparin, were more likely to experience decreases in platelet counts than were those on heparin alone. These decreases were reversible upon discontinuation of AGGRASTAT. 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 AGGRASTAT. 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 AGGRASTAT infusion, during initial treatment, and during readministration of AGGRASTAT. Some cases have been associated with severe thrombocytopenia (platelet counts <10,000/mm3). No information is available on the formation of antibodies to tirofiban.

Usage information

Dosing and administration
2 DOSAGE AND ADMINISTRATION Administer intravenously 25 mcg/kg within 5 minutes and then 0.15 mcg/kg/min for up to 18 hours. In patients with creatinine clearance ≤60 mL/min, give 25 mcg/kg within 5 minutes and then 0.075 mcg/kg/min. (2) 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 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 Withdraw the bolus dose of AGGRASTAT from the 15 mL premixed bolus vial into a syringe. Alternatively, the bolus dose of AGGRASTAT may be administered from the 100 mL premixed vial or from the 250 mL premixed bag. Do not dilute. Administer the bolus dose within 5 minutes via a syringe or IV pump. Immediately following the bolus dose administration, administer the maintenance infusion from the 100 mL premixed vial or 250 mL premixed bag via an IV pump. Discard any unused portion left in the vial or bag. The recommended bolus volume using the 15 mL premixed bolus vial can be calculated using the following equation: The recommended bolus volume using the 100 mL premixed vial or 250 mL premixed bag can be calculated using the following equation: The recommended infusion rate for patients with CrCl (Creatinine Clearance) >60 mL/min using the 100 mL premixed vial or 250 mL premixed bag can be calculated using the following equation: Example calculation of infusion rate for 60 kg patient with CrCl >60 mL/min using the 100 mL premixed vial or 250 mL premixed bag: Drug Compatibilities AGGRASTAT 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 AGGRASTAT through the same IV line as diazepam. Do not add other drugs or remove solution directly from the bag with a syringe. equation-1 equation-2 equation-3 equation-4 2.3 Dose Adjustment for Renal Impairment The recommended dosage in patients with CrCl ≤60 mL/min 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 vial or 250 mL premixed bag can be calculated using the following equation: equation-5
Use in special populations
8 USE IN SPECIFIC POPULATIONS Renal Insufficiency: Reduce the dose in patients with severe renal insufficiency. (8.6) 8.1 Pregnancy Pregnancy Category B There are no adequate and well-controlled studies in pregnant women. Tirofiban has been shown to cross the placenta in pregnant rats and rabbits. 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. 8.3 Nursing Mothers It is not known whether tirofiban is excreted in human milk. However, significant levels of tirofiban were shown to be present in rat milk. Because many drugs are excreted in human milk, and because of the potential for adverse effects on the nursing infant, discontinue nursing or discontinue AGGRASTAT. 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 AGGRASTAT, 43% were 65 years and over, while 12% were 75 and over. With respect to efficacy, the effect of AGGRASTAT in the elderly (≥65 years) appeared similar to that seen in younger patients (<65 years). Elderly patients receiving AGGRASTAT 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 AGGRASTAT 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 AGGRASTAT. Reduce the dosage of AGGRASTAT in patients with severe renal insufficiency [see Dosage and Administration (2) and Clinical Pharmacology (12.3)]. Safety and efficacy of AGGRASTAT has not been established in patients on hemodialysis.
Pregnancy and lactation
8.3 Nursing Mothers It is not known whether tirofiban is excreted in human milk. However, significant levels of tirofiban were shown to be present in rat milk. Because many drugs are excreted in human milk, and because of the potential for adverse effects on the nursing infant, discontinue nursing or discontinue AGGRASTAT.

Interactions

7 DRUG INTERACTIONS Concomitant use of fibrinolytics, anticoagulants and antiplatelet drugs increases the risk of bleeding. Coadministration of fibrinolytics, anticoagulants and antiplatelet agents, increases the risk of bleeding. (7)
