These Highlights Do Not Include All The Information Needed To Use Eptifibatide Injection Safely And Effectively. See Full Prescribing Information For Eptifibatide Injection.

Use of Thrombolytics, Anticoagulants, and Other Antiplatelet Agents

Risk factors for bleeding include older age, a history of bleeding disorders, and concomitant use of drugs that increase the risk of bleeding (thrombolytics, oral anticoagulants, nonsteroidal anti-inflammatory drugs, and P2Y₁₂ inhibitors). Concomitant treatment with other inhibitors of platelet receptor glycoprotein (GP) IIb/IIIa should be avoided. In patients treated with heparin, bleeding can be minimized by close monitoring of the aPTT and ACT [see Dosage and Administration (2)].

Bleeding is the most common complication encountered during eptifibatide therapy. Administration of eptifibatide is associated with an increase in major and minor bleeding, as classified by the criteria of the Thrombolysis in Myocardial Infarction Study group (TIMI) [see Adverse Reactions (6.1)]. Most major bleeding associated with eptifibatide has been at the arterial access site for cardiac catheterization or from the gastrointestinal or genitourinary tract. Minimize the use of arterial and venous punctures, intramuscular injections, and the use of urinary catheters, nasotracheal intubation, and nasogastric tubes. When obtaining intravenous access, avoid non-compressible sites (e.g., subclavian or jugular veins).

There has been only limited experience with overdosage of eptifibatide. There were 8 patients in the IMPACT II study, 9 patients in the PURSUIT study, and no patients in the ESPRIT study who received bolus doses and/or infusion doses more than double those called for in the protocols. None of these patients experienced an intracranial bleed or other major bleeding.

Eptifibatide was not lethal to rats, rabbits, or monkeys when administered by continuous intravenous infusion for 90 minutes at a total dose of 45 mg/kg (about 2 to 5 times the recommended maximum daily human dose on a body surface area basis). Symptoms of acute toxicity were loss of righting reflex, dyspnea, ptosis, and decreased muscle tone in rabbits and petechial hemorrhages in the femoral and abdominal areas of monkeys.

From in vitro studies, eptifibatide is not extensively bound to plasma proteins and thus may be cleared from plasma by dialysis.

Eptifibatide is a cyclic heptapeptide containing 6 amino acids and 1 mercaptopropionyl (des-amino cysteinyl) residue. An interchain disulfide bridge is formed between the cysteine amide and the mercaptopropionyl moieties. Chemically it is N⁶-(aminoiminomethyl)-N²-(3-mercapto-1-oxopropyl)-L-lysylglycyl-L-α-aspartyl-L-tryptophyl-L-prolyl-L-cysteinamide, cyclic (1→6)-disulfide. Eptifibatide binds to the platelet receptor glycoprotein (GP) IIb/IIIa of human platelets and inhibits platelet aggregation.

The eptifibatide peptide is produced by solution-phase peptide synthesis, and is purified by preparative reverse-phase liquid chromatography and lyophilized. The structural formula is:

Eptifibatide Injection is a clear, colorless, sterile, non-pyrogenic solution for intravenous (IV) use with an empirical formula of C₃₅H₄₉N₁₁O₉S₂ and a molecular weight of 831.96. Each 10 mL vial contains 2 mg per mL of eptifibatide and each 100 mL vial contains either 0.75 mg per mL of eptifibatide or 2 mg per mL of eptifibatide. Each vial of either size also contains 5.25 mg per mL citric acid and sodium hydroxide to adjust the pH to 5.35.

Eptifibatide Injection is supplied as follows:

Safety and effectiveness of eptifibatide in pediatric patients have not been studied.

The PURSUIT and IMPACT II clinical studies enrolled patients up to the age of 94 years (45% were age 65 and over; 12% were age 75 and older). There was no apparent difference in efficacy between older and younger patients treated with eptifibatide. The incidence of bleeding complications was higher in the elderly in both placebo and eptifibatide groups, and the incremental risk of eptifibatide-associated bleeding was greater in the older patients. No dose adjustment was made for elderly patients, but patients over 75 years of age had to weigh at least 50 kg to be enrolled in the PURSUIT study; no such limitation was stipulated in the ESPRIT study [see Adverse Reactions (6.1)].

Eptifibatide was studied in 3 placebo-controlled, randomized studies. PURSUIT evaluated patients with acute coronary syndromes: UA or NSTEMI. Two other studies, ESPRIT and IMPACT II, evaluated patients about to undergo a PCI. Patients underwent primarily balloon angioplasty in IMPACT II and intracoronary stent placement, with or without angioplasty, in ESPRIT.

Treatment with eptifibatide is contraindicated in patients with:

• A history of bleeding diathesis, or evidence of active abnormal bleeding within the previous 30 days
• Severe hypertension (systolic blood pressure >200 mm Hg or diastolic blood pressure >110 mm Hg) not adequately controlled on antihypertensive therapy
• Major surgery within the preceding 6 weeks
• History of stroke within 30 days or any history of hemorrhagic stroke
• Current or planned administration of another parenteral GP IIb/IIIa inhibitor
• Dependency on renal dialysis
• Hypersensitivity to eptifibatide or any component of the product (hypersensitivity reactions that occurred included anaphylaxis and urticaria).

The following serious adverse reaction is also discussed elsewhere in the labeling:

• Bleeding [see Contraindications (4) and Warnings and Precautions (5.1)]

• Coadministration of antiplatelet agents, thrombolytics, heparin, aspirin, and chronic NSAID use increases the risk of bleeding. Avoid concomitant use with other glycoprotein (GP) IIb/IIIa inhibitors. (7.1)

There have been reports of acute, profound thrombocytopenia (immune-mediated and non-immune mediated) with eptifibatide. In the event of acute profound thrombocytopenia or a confirmed platelet decrease to <100,000/mm³, discontinue eptifibatide and heparin (unfractionated or low-molecular weight). Monitor serial platelet counts, assess the presence of drug-dependent antibodies, and treat as appropriate [see Adverse Reactions (6.1)].

There has been no clinical experience with eptifibatide initiated in patients with a baseline platelet count <100,000/mm³. If a patient with low platelet counts is receiving eptifibatide, their platelet count should be monitored closely.

Approximately 50% of eptifibatide is cleared by the kidney in patients with normal renal function. Total drug clearance is decreased by approximately 50% and steady-state plasma eptifibatide concentrations are doubled in patients with an estimated CrCl <50 mL/min (using the Cockcroft-Gault equation). Therefore, the infusion dose should be reduced to 1 mcg/kg/min in such patients [see Dosage and Administration (2)]. The safety and efficacy of eptifibatide in patients dependent on dialysis has not been established.

Infusion of eptifibatide into baboons caused a dose-dependent inhibition of ex vivo platelet aggregation, with complete inhibition of aggregation achieved at infusion rates greater than 5 mcg/kg/min. In a baboon model that is refractory to aspirin and heparin, doses of eptifibatide that inhibit aggregation prevented acute thrombosis with only a modest prolongation (2- to 3-fold) of the bleeding time. Platelet aggregation in dogs was also inhibited by infusions of eptifibatide, with complete inhibition at 2 mcg/kg/min. This infusion dose completely inhibited canine coronary thrombosis induced by coronary artery injury (Folts model).

Human pharmacodynamic data were obtained in healthy subjects and in patients presenting with UA or NSTEMI and/or undergoing percutaneous coronary intervention. Studies in healthy subjects enrolled only males; patient studies enrolled approximately one-third women. In these studies, eptifibatide inhibited ex vivo platelet aggregation induced by adenosine diphosphate (ADP) and other agonists in a dose- and concentration-dependent manner. The effect of eptifibatide was observed immediately after administration of a 180 mcg/kg intravenous bolus. Table 4 shows the effects of dosing regimens of eptifibatide used in the IMPACT II and PURSUIT studies on ex vivo platelet aggregation induced by 20 μM ADP in PPACK-anticoagulated platelet-rich plasma and on bleeding time. The effects of the dosing regimen used in ESPRIT on platelet aggregation have not been studied.

The eptifibatide dosing regimen used in the ESPRIT study included two 180 mcg/kg bolus doses given 10 minutes apart combined with a continuous 2 mcg/kg/min infusion.

When administered alone, eptifibatide has no measurable effect on PT or aPTT.

There were no important differences between men and women or between age groups in the pharmacodynamic properties of eptifibatide. Differences among ethnic groups have not been assessed.

The pharmacokinetics of eptifibatide are linear and dose-proportional for bolus doses ranging from 90 to 250 mcg/kg and infusion rates from 0.5 to 3 mcg/kg/min. Plasma elimination half-life is approximately 2.5 hours. Administration of a single 180 mcg/kg bolus combined with an infusion produces an early peak level, followed by a small decline prior to attaining steady state (within 4 to 6 hours). This decline can be prevented by administering a second 180 mcg/kg bolus 10 minutes after the first. The extent of eptifibatide binding to human plasma protein is about 25%. Clearance in patients with coronary artery disease is about 55 mL/kg/h. In healthy subjects, renal clearance accounts for approximately 50% of total body clearance, with the majority of the drug excreted in the urine as eptifibatide, deaminated eptifibatide, and other, more polar metabolites. No major metabolites have been detected in human plasma.

Eptifibatide Injection is a platelet aggregation inhibitor indicated for:

• Treatment of acute coronary syndrome (ACS) managed medically or with percutaneous coronary intervention (PCI) (1.1)
• Treatment of patients undergoing PCI (including intracoronary stenting) (1.2)

Eptifibatide reversibly inhibits platelet aggregation by preventing the binding of fibrinogen, von Willebrand factor, and other adhesive ligands to GP IIb/IIIa. When administered intravenously, eptifibatide inhibits ex vivo platelet aggregation in a dose- and concentration-dependent manner. Platelet aggregation inhibition is reversible following cessation of the eptifibatide infusion; this is thought to result from dissociation of eptifibatide from the platelet.

• Eptifibatide can cause serious bleeding. If bleeding cannot be controlled, discontinue eptifibatide immediately. Minimize vascular and other traumas. If heparin is given concomitantly, monitor aPTT or ACT. (5.1)
• Thrombocytopenia: Discontinue eptifibatide and heparin. Monitor and treat condition appropriately. (5.2)

Before infusion of eptifibatide injection, the following laboratory tests should be performed to identify pre-existing hemostatic abnormalities: hematocrit or hemoglobin, platelet count, serum creatinine, and PT/aPTT. In patients undergoing PCI, the activated clotting time (ACT) should also be measured.

The activated partial thromboplastin time (aPTT) should be maintained between 50 and 70 seconds unless PCI is to be performed. In patients treated with heparin, bleeding can be minimized by close monitoring of the aPTT and ACT.

• 20 mg of Eptifibatide Injection in 10 mL (2 mg per mL), for intravenous bolus.
• 75 mg of Eptifibatide Injection in 100 mL (0.75 mg per mL), for intravenous infusion.
• 200 mg of Eptifibatide Injection in 100 mL (2 mg per mL), for intravenous infusion.

The following adverse reactions have been reported in post-approval use of eptifibatide in combination with heparin and aspirin. Because the reactions below are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure: cerebral, GI, and pulmonary hemorrhage. Fatal bleeding reactions have been reported. Acute profound thrombocytopenia, as well as immune-mediated thrombocytopenia, have been reported [see Adverse Reactions (6.1)].

• Geriatric Use: Risk of bleeding increases with age. (8.5)

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies 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.

A total of 16,782 patients were treated in the Phase III clinical trials (PURSUIT, ESPRIT, and IMPACT II) [see Clinical Studies (14)]. These 16,782 patients had a mean age of 62 years (range: 20 to 94 years). Eighty-nine percent of the patients were Caucasian, with the remainder being predominantly Black (5%) and Hispanic (5%). Sixty-eight percent were men. Because of the different regimens used in PURSUIT, IMPACT II, and ESPRIT, data from the 3 studies were not pooled.

Bleeding and hypotension were the most commonly reported adverse reactions (incidence ≥5% and greater than placebo) in the eptifibatide controlled clinical trial database.

Eptifibatide Injection is indicated to decrease the rate of a combined endpoint of death or new myocardial infarction (MI) in patients with ACS (unstable angina [UA]/non-ST-elevation myocardial infarction [NSTEMI]), including patients who are to be managed medically and those undergoing percutaneous coronary intervention (PCI).

Advise the patient to inform the doctor or healthcare provider about any medical conditions, medications, and allergies.

• Inspect eptifibatide injection for particulate matter and discoloration prior to administration, whenever solution and container permit.
• May administer eptifibatide injection in the same intravenous line as alteplase, atropine, dobutamine, heparin, lidocaine, meperidine, metoprolol, midazolam, morphine, nitroglycerin, or verapamil. Do not administer eptifibatide injection through the same intravenous line as furosemide.
• May administer eptifibatide injection in the same IV line with 0.9% NaCl or 0.9% NaCl/5% dextrose. With either vehicle, the infusion may also contain up to 60 mEq/L of potassium chloride.
• Withdraw the bolus dose(s) of eptifibatide injection from the 10 mL vial into a syringe. Administer the bolus dose(s) by IV push.
• Immediately following the bolus dose administration, initiate a continuous infusion of eptifibatide injection. When using an intravenous infusion pump, administer eptifibatide injection undiluted directly from the 100 mL vial. Spike the 100 mL vial with a vented infusion set. Center the spike within the circle on the stopper top.
• Discard any unused portion left in the vial.

Administer eptifibatide injection by volume according to patient weight (see Table 1).

Eptifibatide injection should be given concomitantly with heparin dosed to achieve the following parameters:

During Medical Management: Target aPTT 50 to 70 seconds

• If weight greater than or equal to 70 kg, 5,000 unit bolus followed by infusion of 1,000 units/h.
• If weight less than 70 kg, 60 units/kg bolus followed by infusion of 12 units/kg/h.

During PCI: Target ACT 200 to 300 seconds

• If heparin is initiated prior to PCI, additional boluses during PCI to maintain an ACT target of 200 to 300 seconds.
• Heparin infusion after the PCI is discouraged.

Eptifibatide Injection is indicated to decrease the rate of a combined endpoint of death, new MI, or need for urgent intervention in patients undergoing PCI, including those undergoing intracoronary stenting [see Clinical Studies (14.1, 14.2)].

Non-ST-segment elevation acute coronary syndrome is defined as prolonged (≥10 minutes) symptoms of cardiac ischemia within the previous 24 hours associated with either ST-segment changes (elevations between 0.6 mm and 1 mm or depression >0.5 mm), T-wave inversion (>1 mm), or positive CK-MB. This definition includes “unstable angina” and “NSTEMI” but excludes MI that is associated with Q waves or greater degrees of ST-segment elevation.

• Eptifibatide injection should be given concomitantly with heparin to achieve a target ACT of 200 to 300 seconds. Administer 60 units/kg bolus initially in patients not treated with heparin within 6 hours prior to PCI.
• Additional boluses during PCI to maintain ACT within target.
• Heparin infusion after the PCI is strongly discouraged.

Patients requiring thrombolytic therapy should discontinue eptifibatide injection.

No long-term studies in animals have been performed to evaluate the carcinogenic potential of eptifibatide. Eptifibatide was not genotoxic in the Ames test, the mouse lymphoma cell (L 5178Y, TK+/-) forward mutation test, the human lymphocyte chromosome aberration test, or the mouse micronucleus test. Administered by continuous intravenous infusion at total daily doses up to 72 mg/kg/day (about 4 times the recommended maximum daily human dose on a body surface area basis), eptifibatide had no effect on fertility and reproductive performance of male and female rats.

Coadministration of antiplatelet agents, thrombolytics, heparin, aspirin, and chronic NSAID use increases the risk of bleeding. Concomitant treatment with other inhibitors of platelet receptor GP IIb/IIIa should be avoided.

Use of Thrombolytics, Anticoagulants, and Other Antiplatelet Agents

Risk factors for bleeding include older age, a history of bleeding disorders, and concomitant use of drugs that increase the risk of bleeding (thrombolytics, oral anticoagulants, nonsteroidal anti-inflammatory drugs, and P2Y₁₂ inhibitors). Concomitant treatment with other inhibitors of platelet receptor glycoprotein (GP) IIb/IIIa should be avoided. In patients treated with heparin, bleeding can be minimized by close monitoring of the aPTT and ACT [see Dosage and Administration (2)].

• May administer eptifibatide injection in the same intravenous line as alteplase, atropine, dobutamine, heparin, lidocaine, meperidine, metoprolol, midazolam, morphine, nitroglycerin, or verapamil. Do not administer eptifibatide injection through the same intravenous line as furosemide.
• May administer eptifibatide injection in the same IV line with 0.9% NaCl or 0.9% NaCl/5% dextrose. With either vehicle, the infusion may also contain up to 60 mEq/L of potassium chloride.
• Withdraw the bolus dose(s) of eptifibatide injection from the 10 mL vial into a syringe. Administer the bolus dose(s) by IV push.
• Immediately following the bolus dose administration, initiate a continuous infusion of eptifibatide injection. When using an intravenous infusion pump, administer eptifibatide injection undiluted directly from the 100 mL vial. Spike the 100 mL vial with a vented infusion set. Center the spike within the circle on the stopper top.
• Discard any unused portion left in the vial.

Administer eptifibatide injection by volume according to patient weight (see Table 1).

Eptifibatide injection should be given concomitantly with heparin dosed to achieve the following parameters:

During Medical Management: Target aPTT 50 to 70 seconds

• If weight greater than or equal to 70 kg, 5,000 unit bolus followed by infusion of 1,000 units/h.
• If weight less than 70 kg, 60 units/kg bolus followed by infusion of 12 units/kg/h.

During PCI: Target ACT 200 to 300 seconds

• If heparin is initiated prior to PCI, additional boluses during PCI to maintain an ACT target of 200 to 300 seconds.
• Heparin infusion after the PCI is discouraged.

Eptifibatide Injection is indicated to decrease the rate of a combined endpoint of death, new MI, or need for urgent intervention in patients undergoing PCI, including those undergoing intracoronary stenting [see Clinical Studies (14.1, 14.2)].

Non-ST-segment elevation acute coronary syndrome is defined as prolonged (≥10 minutes) symptoms of cardiac ischemia within the previous 24 hours associated with either ST-segment changes (elevations between 0.6 mm and 1 mm or depression >0.5 mm), T-wave inversion (>1 mm), or positive CK-MB. This definition includes “unstable angina” and “NSTEMI” but excludes MI that is associated with Q waves or greater degrees of ST-segment elevation.

• Eptifibatide injection should be given concomitantly with heparin to achieve a target ACT of 200 to 300 seconds. Administer 60 units/kg bolus initially in patients not treated with heparin within 6 hours prior to PCI.
• Additional boluses during PCI to maintain ACT within target.
• Heparin infusion after the PCI is strongly discouraged.

Patients requiring thrombolytic therapy should discontinue eptifibatide injection.

No long-term studies in animals have been performed to evaluate the carcinogenic potential of eptifibatide. Eptifibatide was not genotoxic in the Ames test, the mouse lymphoma cell (L 5178Y, TK+/-) forward mutation test, the human lymphocyte chromosome aberration test, or the mouse micronucleus test. Administered by continuous intravenous infusion at total daily doses up to 72 mg/kg/day (about 4 times the recommended maximum daily human dose on a body surface area basis), eptifibatide had no effect on fertility and reproductive performance of male and female rats.

Coadministration of antiplatelet agents, thrombolytics, heparin, aspirin, and chronic NSAID use increases the risk of bleeding. Concomitant treatment with other inhibitors of platelet receptor GP IIb/IIIa should be avoided.
