Eptifibatide
Injection, Solution · Intravenous
Uses
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 ) 1.1 Acute Coronary Syndrome (ACS) 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). 1.2 Percutaneous Coronary Intervention (PCI) 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 )] .
Dosage and administration
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. ACS or PCI: 180 mcg/kg IV bolus as soon as possible after diagnosis followed by infusion at 2 mcg/kg/min. ( 2.1 , 2.2 ) PCI: Add a second 180 mcg/kg bolus at 10 minutes. ( 2.2 ) In patients with creatinine clearance less than 50 mL/min, reduce the infusion to 1 mcg/kg/min. 2.1 , 2.2 , 2.3 ) 2.1 Dosage in Acute Coronary Syndrome (ACS) Indication Normal Renal Function Creatinine Clearance less than 50 mL/min Patients with ACS 180 mcg/kg intravenous (IV) bolus as soon as possible after diagnosis, followed by continuous infusion of 2 mcg/kg/min 180 mcg/kg IV bolus as soon as possible after diagnosis, followed by continuous infusion of 1 mcg/kg/min Infusion should continue until hospital discharge or initiation of coronary artery bypass graft surgery (CABG), up to 72 hours. If a patient is to undergo PCI, the infusion should be continued until hospital discharge or for up to 18 to 24 hours after the procedure, whichever comes first, allowing for up to 96 hours of therapy. Aspirin, 160 to 325 mg, should be given daily. 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, 5000-unit bolus followed by infusion of 1000 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. 2.2 Dosage in Percutaneous Coronary Intervention (PCI) Indication Normal Renal Function Creatinine Clearance less than 50 mL/min Patients with PCI 180 mcg/kg IV bolus immediately before PCI followed by continuous infusion of 2 mcg/kg/min and a second bolus of 180 mcg/kg (given 10 minutes after the first bolus) 180 mcg/kg IV bolus immediately before PCI followed by continuous infusion of 1 mcg/kg/min and a second bolus of 180 mcg/kg (given 10 minutes after the first bolus) Infusion should be continued until hospital discharge, or for up to 18 to 24 hours, whichever comes first. A minimum of 12 hours of infusion is recommended. In patients who undergo CABG surgery, eptifibatide infusion should be discontinued prior to surgery. Aspirin, 160 to 325 mg, should be given 1 to 24 hours prior to PCI and daily thereafter. 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. 2.3 Important Administration Instructions 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 ). Table 1.

Contraindications
Treatment with eptifibatide injection 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 injection or any component of the product (hypersensitivity reactions that occurred included anaphylaxis and urticaria). Bleeding diathesis or bleeding within the previous 30 days. ( 4 ) Severe uncontrolled hypertension. ( 4 ) Major surgery within the preceding 6 weeks. ( 4 ) Stroke within 30 days or any history of hemorrhagic stroke. ( 4 ) Coadministration of another parenteral GP IIb/IIIa inhibitor. ( 4 ) Dependency on renal dialysis. ( 4 ) Known hypersensitivity to any component of the product. ( 4 )
Warnings and precautions
Eptifibatide injection can cause serious bleeding. If bleeding cannot be controlled, discontinue eptifibatide injection immediately. Minimize vascular and other traumas. If heparin is given concomitantly, monitor aPTT or ACT. ( 5.1 ) Thrombocytopenia: Discontinue eptifibatide injection and heparin. Monitor and treat condition appropriately. ( 5.2 ) 5.1 Bleeding Bleeding is the most common complication encountered during eptifibatide injection therapy. Administration of eptifibatide injection 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 injection 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). 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 P2Y 12 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 )] . Care of the Femoral Artery Access Site in Patients Undergoing Percutaneous Coronary Intervention (PCI) In patients undergoing PCI, treatment with eptifibatide injection is associated with an increase in major and minor bleeding at the site of arterial sheath placement. After PCI, eptifibatide infusion should be continued until hospital discharge or up to 18 to 24 hours, whichever comes first. Heparin use is discouraged after the PCI procedure. Early sheath removal is encouraged while eptifibatide injection is being infused. Prior to removing the sheath, it is recommended that heparin be discontinued for 3 to 4 hours and an aPTT of <45 seconds or ACT <150 seconds be achieved. In any case, both heparin and eptifibatide injection should be discontinued and sheath hemostasis should be achieved at least 2 to 4 hours before hospital discharge. If bleeding at access site cannot be controlled with pressure, infusion of eptifibatide injection and heparin should be discontinued immediately. 5.2 Thrombocytopenia There have been reports of acute, profound thrombocytopenia (immune-mediated and non-immune mediated) with eptifibatide injection. In the event of acute profound thrombocytopenia or a confirmed platelet decrease to <100,000/mm 3 , discontinue eptifibatide injection 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 injection initiated in patients with a baseline platelet count <100,000/mm 3 . If a patient with low platelet counts is receiving eptifibatide injection, their platelet count should be monitored closely.
Side effects
The following serious adverse reaction is also discussed elsewhere in the labeling: Bleeding [see Contraindications ( 4 ) and Warnings and Precautions ( 5.1 )] Bleeding and hypotension are the most commonly reported adverse reactions. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Slate Run Pharmaceuticals, LLC at 1-888-341-9214 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience 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: 20-94 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 injection controlled clinical trial database. Bleeding The incidence of bleeding and transfusions in the PURSUIT and ESPRIT studies are shown in Table 2 . Bleeding was classified as major or minor by the criteria of the TIMI study group. Major bleeding consisted of intracranial hemorrhage and other bleeding that led to decreases in hemoglobin greater than 5 g/dL. Minor bleeding included spontaneous gross hematuria, spontaneous hematemesis, other observed blood loss with a hemoglobin decrease of more than 3 g/dL, and other hemoglobin decreases that were greater than 4 g/dL but less than 5 g/dL. In patients who received transfusions, the corresponding loss in hemoglobin was estimated through an adaptation of the method of Landefeld et al. Table 2. Bleeding and Transfusions in the PURSUIT and ESPRIT Studies Note: Denominator is based on patients for whom data are available. * For major and minor bleeding, patients are counted only once according to the most severe classification. † Includes transfusions of whole blood, packed red blood cells, fresh frozen plasma, cryoprecipitate, platelets, and autotransfusion during the initial hospitalization. PURSUIT (ACS) Placebo n (%) Eptifibatide Injection 180/2 n (%) Patients 4696 4679 Major bleeding* 425 (9.3%) 498 (10.8%) Minor bleeding* 347 (7.6%) 604 (13.1%) Requiring transfusions† 490 (10.4%) 601 (12.8%) ESPRIT (PCI) Placebo n (%) Eptifibatide Injection 180/2/180 n (%) Patients 1024 1040 Major bleeding* 4 (0.4%) 13 (1.3%) Minor bleeding* 18 (2%) 29 (3%) Requiring transfusions† 11 (1.1%) 16 (1.5%) The majority of major bleeding reactions in the ESPRIT study occurred at the vascular access site (1 and 8 patients, or 0.1% and 0.8% in the placebo and eptifibatide injection groups, respectively). Bleeding at “other” locations occurred in 0.2% and 0.4% of patients, respectively. In the PURSUIT study, the greatest increase in major bleeding in eptifibatide-treated patients compared to placebo-treated patients was also associated with bleeding at the femoral artery access site (2.8% versus 1.3%). Oropharyngeal (primarily gingival), genitourinary, gastrointestinal, and retroperitoneal bleeding were also seen more commonly in eptifibatide-treated patients compared to placebo-treated patients. Among patients experiencing a major bleed in the IMPACT II study, an increase in bleeding on eptifibatide injection versus placebo was observed only for the femoral artery access site (3.2% versus 2.8%). Table 3 displays the incidence of TIMI major bleeding according to the cardiac procedures carried out in the PURSUIT study. The most common bleeding complications were related to cardiac revascularization (CABG-related or femoral artery access site bleeding). A corresponding table for ESPRIT is not presented, as every patient underwent PCI in the ESPRIT study and only 11 patients underwent CABG. Table 3. Major Bleeding by Procedures in the PURSUIT Study Note: Denominators are based on the total number of patients whose TIMI classification was resolved. Placebo n (%) Eptifibatide Injection 180/2 n (%) Patients 4577 4604 Overall incidence of major bleeding 425 (9.3%) 498 (10.8%) Breakdown by procedure: CABG 375 (8.2%) 377 (8.2%) Angioplasty without CABG 27 (0.6%) 64 (1.4%) Angiography without angioplasty or CABG 11 (0.2%) 29 (0.6%) Medical therapy only 12 (0.3%) 28 (0.6%) In the PURSUIT and ESPRIT studies, the risk of major bleeding with eptifibatide injection increased as patient weight decreased. This relationship was most apparent for patients weighing less than 70 kg. Bleeding resulting in discontinuation of the study drug was more frequent among patients receiving eptifibatide injection than placebo (4.6% versus 0.9% in ESPRIT, 8% versus 1% in PURSUIT, 3.5% versus 1.9% in IMPACT II). Intracranial Hemorrhage and Stroke Intracranial hemorrhage was rare in the PURSUIT, IMPACT II, and ESPRIT clinical studies. In the PURSUIT study, 3 patients in the placebo group, 1 patient in the group treated with eptifibatide injection 180/1.3, and 5 patients in the group treated with eptifibatide injection 180/2 experienced a hemorrhagic stroke. The overall incidence of stroke was 0.5% in patients receiving eptifibatide injection 180/1.3, 0.7% in patients receiving eptifibatide injection 180/2, and 0.8% in placebo patients. In the IMPACT II study, intracranial hemorrhage was experienced by 1 patient treated with eptifibatide injection 135/0.5, 2 patients treated with eptifibatide injection 135/0.75, and 2 patients in the placebo group.
Drug interactions
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 ) 7.1 Use of Thrombolytics, Anticoagulants, and Other Antiplatelet Agents 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 in specific populations
Geriatric Use: Risk of bleeding increases with age. ( 8.5 ) 8.1 Pregnancy Risk Summary Available data on eptifibatide use in pregnant women from published literature and the pharmacovigilance database are insufficient to establish a drug-associated risk of 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 ] . In animal reproduction studies, there was no evidence of adverse developmental effects when eptifibatide was administered intravenously to pregnant rats and rabbits at approximately 4 times the recommended maximum daily human dose. 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. Therapy for the pregnant woman should not be withheld because of potential concerns regarding the effects of eptifibatide injection on the fetus. Data Animal Data: Embryo-fetal development studies have been performed by continuous intravenous infusion of eptifibatide in pregnant rats during the period of organogenesis at total daily doses of up to 72 mg/kg/day (about 4 times the recommended maximum daily human dose on a body surface area basis) and in pregnant rabbits during the period of organogenesis at total daily doses of up to 36 mg/kg/day (also about 4 times the recommended maximum daily human dose on a body surface area basis). These studies revealed no evidence of harm to the fetus due to eptifibatide. 8.2 Lactation Risk Summary There are no available data on the presence of eptifibatide in human milk, the effects on the breastfed infant, or the effects on milk production. As eptifibatide is a peptide, it is likely to be destroyed in the infant’s gastrointestinal tract and not absorbed orally by the breastfed infant. 8.4 Pediatric Use Safety and effectiveness of eptifibatide injection in pediatric patients have not been studied. 8.5 Geriatric Use 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 injection. The incidence of bleeding complications was higher in the elderly in both placebo and eptifibatide injection 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 )] . 8.6 Renal Impairment 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 injection 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 injection in patients dependent on dialysis has not been established.
Pregnancy
8.1 Pregnancy Risk Summary Available data on eptifibatide use in pregnant women from published literature and the pharmacovigilance database are insufficient to establish a drug-associated risk of 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 ] . In animal reproduction studies, there was no evidence of adverse developmental effects when eptifibatide was administered intravenously to pregnant rats and rabbits at approximately 4 times the recommended maximum daily human dose. 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. Therapy for the pregnant woman should not be withheld because of potential concerns regarding the effects of eptifibatide injection on the fetus. Data Animal Data: Embryo-fetal development studies have been performed by continuous intravenous infusion of eptifibatide in pregnant rats during the period of organogenesis at total daily doses of up to 72 mg/kg/day (about 4 times the recommended maximum daily human dose on a body surface area basis) and in pregnant rabbits during the period of organogenesis at total daily doses of up to 36 mg/kg/day (also about 4 times the recommended maximum daily human dose on a body surface area basis). These studies revealed no evidence of harm to the fetus due to eptifibatide.
Pediatric use
8.4 Pediatric Use Safety and effectiveness of eptifibatide injection in pediatric patients have not been studied.
Geriatric use
8.5 Geriatric Use 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 injection. The incidence of bleeding complications was higher in the elderly in both placebo and eptifibatide injection 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 )] .
Overdosage
There has been only limited experience with overdosage of eptifibatide injection. 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.
Description
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 N 6 -(aminoiminomethyl)-N 2 -(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 C 35 H 49 N 11 O 9 S 2 and a molecular weight of 831.96. Each 10 mL vial contains 2 mg/mL of eptifibatide injection and each 100 mL vial contains 0.75 mg/mL of eptifibatide injection. Each vial of either size also contains 5.25 mg/mL citric acid and sodium hydroxide to adjust the pH to 5.35. structural formula
Mechanism of action
12.1 Mechanism of Action 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.
