WARNING: CARDIAC TOXICITY, SECONDARY MALIGNANCIES, EXTRAVASATION AND TISSUE NECROSIS, and SEVERE MYELOSUPPRESSION • Cardiac Toxicity: Myocardial damage, including acute left ventricular failure, can occur with ELLENCE. The risk of cardiomyopathy is proportional to the cumulative exposure with incidence rates from 0.9% at a cumulative dose of 550 mg/m 2 , 1.6% at 700 mg/m 2 , and 3.3% at 900 mg/m 2 . The risk of cardiomyopathy is further increased with concomitant cardiotoxic therapy. Assess left ventricular ejection fraction (LVEF) before and regularly during and after treatment with ELLENCE [see Warnings and Precautions (5.1) ] . • Secondary Malignancies: Secondary acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS) occur at a higher incidence in patients treated with anthracyclines, including ELLENCE [see Warnings and Precautions (5.2) ] . • Extravasation and Tissue Necrosis: Extravasation of ELLENCE can result in severe local tissue injury and necrosis requiring wide excision of the affected area and skin grafting. Immediately terminate the drug and apply ice to the affected area [see Warnings and Precautions (5.3) ] . • Severe myelosuppression resulting in serious infection, septic shock, requirement for transfusions, hospitalization, and death may occur [see Warnings and Precautions (5.4) ] .

Contraindications
- 4 CONTRAINDICATIONS ELLENCE is contraindicated in patients with: • Severe myocardial insufficiency [see Warnings and Precautions (5.1) ] • Recent myocardial infarction or severe arrhythmias, or previous treatment with maximum cumulative dose of anthracyclines [see Warnings and Precautions (5.1) ] • Severe persistent drug-induced myelosuppression [see Warnings and Precautions (5.4) ] • Severe hepatic impairment (defined as Child-Pugh Class C or serum bilirubin level greater than 5 mg/dL) [see Warnings and Precautions (5.5) ] • Severe hypersensitivity to ELLENCE, other anthracyclines, or anthracenediones [see Adverse Reactions (6.1) ] • Severe myocardial insufficiency ( 4 ).
- • Recent myocardial infarction ( 4 ).
- • Severe persistent drug-induced myelosuppression ( 4 ).
- • Severe hepatic impairment ( 4 ).
- • Severe hypersensitivity to ELLENCE, other anthracyclines, or anthracenediones ( 4 ).
Precautions
- Use in Patients with Hepatic Impairment: Monitor serum total bilirubin and AST levels before and during treatment with ELLENCE.
- In patients with elevated serum AST or serum total bilirubin, dosage reductions or discontinuation may be required ( 2.3 , 5.5 ). • Tumor Lysis Syndrome: Evaluate blood uric acid levels, potassium, calcium, phosphate, and creatinine after initial treatment.
- Consider hydration, urine alkalinization, and prophylaxis with allopurinol to minimize potential complications of hyperuricemia and tumor lysis syndrome ( 5.7 ). • Thrombophlebitis and Thromboembolic Events: Thrombophlebitis and thromboembolic events, including pulmonary embolism (in some cases fatal) have been reported with the use of ELLENCE.
- Venous sclerosis may result from an injection into a small vessel or from repeated injections into the same vein ( 5.9 ). • Administration of live or live-attenuated vaccines in patients immunocompromised by chemotherapeutic agents including ELLENCE, may result in serious or fatal infections ( 5.7 ). • Potentiation of Radiation Toxicity and Radiation Recall: Administration of ELLENCE after previous radiation therapy may induce an inflammatory recall reaction at the site of the irradiation ( 5.10 ). • Embryo-Fetal Toxicity: ELLENCE can cause fetal harm.
- Advise patients of the potential risk to a fetus and to use effective contraception ( 5.11 , 8.1 , 8.3 ). 5.1 Cardiac Toxicity ELLENCE and other anthracycline drugs can result in either early (or acute) or late (delayed) cardiac toxicity.
- The principal manifestations of early cardiac toxicity are sinus tachycardia and/or electrocardiogram (ECG) abnormalities such as non-specific ST-T wave changes.
- However, tachycardia (including premature ventricular contractions and ventricular tachycardia), bradycardia, as well as atrioventricular and bundle-branch block have been reported.
- Early cardiac toxicity does not usually predict the subsequent occurrence of delayed cardiotoxicity and generally should not be considered a reason for suspending treatment with ELLENCE.
- Delayed cardiac toxicity is manifested by reduced left ventricular ejection fraction (LVEF) and/or signs and symptoms of congestive heart failure (CHF).
- If it occurs, late cardiotoxicity usually develops late during therapy with ELLENCE or within 2 to 3 months after completion of treatment, but there are reports of it occurring several months to years after treatment termination.
- In a retrospective survey, including 9144 patients, mostly with solid tumors in advanced stages, the probability of developing CHF increased with increasing cumulative doses of ELLENCE (Figure 1).
- In another retrospective survey of 469 ELLENCE-treated patients with metastatic or early breast cancer, the reported risk of CHF was comparable to that observed in the larger study of over 9000 patients.

Population and organ-function guidance, shown together for faster comparison.
• The recommended starting dose of ELLENCE is 100 to 120 mg/m 2 . Dosage reductions are possible when given in certain combinations ( 2.2 ). • Administer intravenously in repeated 3- to 4-week cycles, either total dose on Day 1 of each cycle or divided equally and given on Days 1 and 8 of each cycle ( 2.2 ). • Consider use of antiemetics when given in conjunction with other emetigenic drugs ( 2.1 ). • Patients administered the 120 mg/m 2 regimen of ELLENCE should receive prophylactic antibiotic therapy ( 2.1 ). • Adjust dosage after the first treatment cycle based on hematologic and nonhematologic toxicities ( 2.3 ). • Reduce dose in patients with hepatic impairment ( 2.3 , 8.6 ). • Consider lower doses in patients with severe renal impairment ( 2.3 , 8.7 ). 2.1 Important Administration Instructions When possible, to reduce the risk of developing cardiotoxicity in patients receiving ELLENCE after stopping treatment with other cardiotoxic agents, especially those with long half-lives such as trastuzumab, delay ELLENCE-based therapy until the other agents have cleared from the circulation [see Warnings and Precautions (5.1) ]. Antiemetics may reduce nausea and vomiting; consider use of antiemetics before administration of ELLENCE or when clinically indicated, particularly when given in conjunction with other emetigenic drugs [see Adverse Reactions (6.1) ]. Patients administered the 120 mg/m 2 regimen of ELLENCE should receive prophylactic antibiotic therapy. 2.2 Recommended Dose The recommended dose of ELLENCE is 100 to 120 mg/m 2 administered as an intravenous bolus [see Dosage and Administration (2.4) ] . The following regimens are recommended: CEF-120: Cyclophosphamide 75 mg/m 2 oral on Days 1 to 14 ELLENCE 60 mg/m 2 intravenously on Days 1 and 8 5-Fluorouracil 500 mg/m 2 intravenously on Days 1 and 8 Repeat every 28 days for 6 cycles FEC-100: 5-Fluorouracil 500 mg/m 2 intravenously on Day 1 ELLENCE 100 mg/m 2 intravenously on Day 1 Cyclophosphamide 500 mg/m 2 intravenously on Day 1 Repeat every 21 days for 6 cycles Administer ELLENCE in repeated 3- to 4-week cycles. The total dose of ELLENCE may be given on Day 1 of each cycle or divided equally and given on Days 1 and 8 of each cycle. 2.3 Dose Modifications ELLENCE dosage adjustments for hematologic and non-hematologic toxicities within a cycle of treatment, is based on nadir platelet counts <50,000/mm 3 , absolute neutrophil counts (ANC) <250/mm 3 , neutropenic fever, or Grades 3/4 nonhematologic toxicity. Reduce ELLENCE Day 1 dose in subsequent cycles to 75% of the Day 1 dose given in the current cycle. Delay Day 1 chemotherapy in subsequent courses of treatment until platelet counts are ≥100,000/mm 3 , ANC ≥1500/mm 3 , and nonhematologic toxicities have recovered to ≤ Grade 1. Cardiac Toxicity Discontinue ELLENCE in patients who develop signs or symptoms of cardiomyopathy [see Warnings and Precautions (5.1) ]. Bone Marrow Dysfunction Consider administering a lower starting dose (75–90 mg/m 2 ) for heavily pretreated patients, patients with pre-existing bone marrow depression, or in the presence of neoplastic bone marrow infiltration [see Warnings and Precautions (5.4) ]. For patients receiving a divided dose of ELLENCE (Day 1 and Day 8), the Day 8 dose should be 75% of Day 1 if platelet counts are 75,000–100,000/mm 3 and ANC is 1000 to 1499/mm 3 . If Day 8 platelet counts are <75,000/mm 3 , ANC <1000/mm 3 , or Grades 3/4 nonhematologic toxicity has occurred, omit the Day 8 dose. Hepatic Impairment In patients with elevated serum AST or serum total bilirubin concentrations [see Warnings and Precautions (5.5) and Clinical Pharmacology (12.3) ] , reduce dosage as follows: • Bilirubin 1.2 to 3 mg/dL or AST 2 to 4 times upper limit of normal 1/2 of recommended starting dose • Bilirubin > 3 mg/dL or AST > 4 times upper limit of normal 1/4 of recommended starting dose Renal Impairment Consider lower doses in patients with severe renal impairment (serum creatinine > 5 mg/dL) [see Warnings and Precautions (5.6) and Clinical Pharmacology (12.3) ] . 2.4 Preparation and Administration Precautions Preparation Storage of the solution for injection at refrigerated conditions can result in the formation of a gelled product. This gelled product will return to a slightly viscous to mobile solution after 2 to a maximum of 4 hours equilibration at controlled room temperature (15–25°C). Inspect parenteral drug products visually for particulate matter and discoloration prior to administration, whenever solution and container permit. ELLENCE is a cytotoxic drug. Follow applicable special handling and disposable procedures 1 [see References (15) ]. Incompatibilities Avoid prolonged contact with any solution of an alkaline pH as it will result in hydrolysis of the drug. Do not mix ELLENCE with heparin or fluorouracil due to chemical incompatibility that may lead to precipitation. ELLENCE can be used in combination with other antitumor agents, but do not mix with other drugs in the same syringe. Administration Administer ELLENCE into the tubing of a freely flowing intravenous infusion (0.9% sodium chloride or 5% glucose solution). Patients receiving initial therapy at the recommended starting doses of 100–120 mg/m 2 should generally have ELLENCE infused over 15–20 minutes. For patients who require lower ELLENCE starting doses due to organ dysfunction or who require modification of ELLENCE doses during therapy, the ELLENCE infusion time may be proportionally decreased, but should not be less than 3 minutes. This technique is intended to minimize the risk of thrombosis or perivenous extravasation, which could lead to severe cellulitis, vesication, or tissue necrosis. A direct push injection is not recommended due to the risk of extravasation, which may occur even in the presence of adequate blood return upon needle aspiration. Venous sclerosis may result from injection into small vessels or repeated injections into the same vein [see Warnings and Precautions (5.3) ]. Storage Use ELLENCE within 24 hours of first penetration of the rubber stopper. Discard any unused solution.
8.4 Pediatric Use Safety and effectiveness of ELLENCE have not been established in pediatric patients. Pediatric patients may be at greater risk for anthracycline-induced acute manifestations of cardiotoxicity or late cardiovascular dysfunction. The pharmacokinetics of epirubicin in pediatric patients have not been evaluated.
Review renal impairment dosing; many agents need CrCl/eGFR adjustment.
- CrCl 0–120: Confirm renal dosing in product SmPC / primary label.
Review hepatic impairment dosing; monitor LFTs if agent is hepatically cleared or hepatotoxic.

Mechanism & disposition
agent.
Read complete mechanism
agent. Although it is known that anthracyclines can interfere with a number of biochemical and biological functions within eukaryotic cells, the precise mechanisms of epirubicin's cytotoxic and/or antiproliferative properties have not been completely elucidated. Epirubicin forms a complex with DNA by intercalation of its planar rings between nucleotide base pairs, with consequent inhibition of nucleic acid (DNA and RNA) and protein synthesis. Such intercalation triggers DNA cleavage by topoisomerase II, resulting in cytocidal activity. Epirubicin also inhibits DNA helicase activity, preventing the enzymatic separation of double-stranded DNA and interfering with replication and transcription. Epirubicin is also involved in oxidation/reduction reactions by generating cytotoxic free radicals. The antiproliferative and cytotoxic activity of epirubicin is thought to result from these or other possible mechanisms. Epirubicin is cytotoxic in vitro to a variety of established murine and human cell lines and primary cultures of human tumors. It is also active in vivo against a variety of murine tumors and human xenografts in athymic mice, including breast tumors.

8.1 Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action, ELLENCE can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] ; avoid the use of ELLENCE during the 1 st trimester. Available human data do not establish the presence or absence of major birth defects and miscarriage related to the use of epirubicin during the 2 nd and 3 rd trimesters. There are reports of fetal and/or neonatal cardiotoxicity following in utero exposure to epirubicin (see Clinical Considerations ). In animal reproduction studies in pregnant rats, epirubicin was embryo-fetal lethal and caused structural abnormalities when administered during organogenesis at doses less than the maximum recommended human dose on a body surface area basis ( see Data ). Advise pregnant women and females of reproductive potential of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. 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 Fetal/Neonatal Adverse Reactions There have been rare reports of fetal and/or neonatal transient ventricular hypokinesia, transient elevation of cardiac enzymes, and a case of fetal demise from suspected anthracycline-induced cardiotoxicity following in utero exposure to epirubicin in 2 nd and/or 3 rd trimesters. Cardiotoxicity is a known risk of anthracycline treatment in adults [see Warnings and Precautions (5.1) ]. Monitor the fetus and/or neonate for cardiotoxicity and perform testing consistent with community standards of care. Data Animal Data Intravenous administration of 0.8 mg/kg/day epirubicin (about 0.04 times the maximum recommended single human dose on a body surface area basis) to rats during Days 5 to 15 of gestation resulted in embryofetal lethality (increased resorptions and post-implantation loss) and caused fetal growth retardation (decreased body weight). Intravenous administration of 2 mg/kg/day epirubicin (about 0.1 times the maximum recommended single human dose on a body surface area basis) to rats on Days 9 and 10 of gestation resulted in embryo-fetal lethality (increased late resorptions, post-implantation losses, and dead fetuses; and decreased live fetuses), retarded fetal growth (decreased body weight), and caused decreased placental weight and numerous external (anal atresia, misshapen tail, abnormal genital tubercle), visceral (primarily gastrointestinal, urinary, and cardiovascular systems), and skeletal (deformed long bones and girdles, rib abnormalities, irregular spinal ossification) malformations. Administration of intravenous epirubicin to rabbits at doses up to 0.2 mg/kg/day (about 0.02 times the maximum recommended single human dose on a body surface area basis) during Days 6 to 18 of gestation was not teratogenic, but a maternally toxic dose of 0.32 mg/kg/day increased abortions and delayed ossification. Administration of a maternally toxic intravenous dose of 1 mg/kg/day epirubicin to rabbits (about 0.1 times the maximum recommended single human dose on a body surface area basis) on Days 10 to 12 of gestation induced abortion, but no other signs of teratogenicity were observed. When doses up to 0.5 mg/kg/day epirubicin were administered to rat dams from Day 17 of gestation to Day 21 after delivery (about 0.025 times the maximum recommended single human dose on a body surface area basis), no permanent changes were observed in the development, functional activity, behavior, or reproductive performance of the offspring.
• Lactation: Advise not to breastfeed ( 8.2 ). • Females and Males of Reproductive Potential: May impair fertility ( 8.3 ). 8.1 Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action, ELLENCE can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] ; avoid the use of ELLENCE during the 1 st trimester.

When doses up to 0.5 mg/kg/day epirubicin were administered to rat dams from Day 17 of gestation to Day 21 after delivery (about 0.025 times the maximum recommended single human dose on a body surface area basis), no permanent changes were observed in the development, functional activity, behavior, or reproductive performance of the offspring. 8.2 Lactation Risk Summary There are no data on the presence of epirubicin in human milk, the effects on the breastfed child, or the effects on milk production. Epirubicin is present in rat milk (see Data ) . When a drug is present in animal milk it is likely the drug will be present in human milk. Because of the potential for serious adverse reactions in the breastfed child, advise lactating women not to breastfeed during treatment with ELLENCE and for at least 7 days after the last dose. Data Animal Data In a peri- and post-natal study, epirubicin was present in milk of rats treated with 0.5 mg/kg/day epirubicin (about 0.025 times the maximum recommended human dose on a body surface area basis). 8.3 Females and Males of Reproductive Potential Pregnancy Testing Verify the pregnancy status in female patients of reproductive potential prior to initiating ELLENCE. Contraception Females ELLENCE can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ] . Advise female patients of reproductive potential to use effective contraception during treatment and for 6 months after the last dose of ELLENCE. Males Based on its mechanism of action and genotoxicity studies, advise male patients with female partners of reproductive potential to use effective contraception during treatment and for 3 months after the last dose of ELLENCE. Advise male patients with pregnant partners use condoms during treatment and for at least 7 days after the last dose of ELLENCE [see Clinical Pharmacology (12.1) and Nonclinical Toxicology (13.1) ] . Infertility Females Based on clinical findings and animal studies, ELLENCE may impair female fertility and result in amenorrhea. Premature menopause can occur. Recovery of menses and ovulation is related to age at treatment [see Nonclinical Toxicology (13.1) ]. Males Based on clinical findings and animal studies, ELLENCE may cause oligospermia, azoospermia, and permanent loss of fertility. Sperm counts have been reported to return to normal levels in some men. This may occur several years after the end of therapy [see Nonclinical Toxicology (13.1) ] . 8.4 Pediatric Use Safety and effectiveness of ELLENCE have not been established in pediatric patients. Pediatric patients may be at greater risk for anthracycline-induced acute manifestations of cardiotoxicity or late cardiovascular dysfunction. The pharmacokinetics of epirubicin in pediatric patients have not been evaluated. 8.5 Geriatric Use Clinical experience in patients who were 65 years of age and older who received ELLENCE chemotherapy regimens for primary breast cancer showed no overall differences in safety and effectiveness compared with younger patients. In elderly female patients, closely monitor for increased toxicity due to the risk of decreased clearance of epirubicin [see Clinical Pharmacology (12.3) ]. 8.6 Hepatic Impairment Epirubicin is eliminated by both hepatic metabolism and biliary excretion and clearance is reduced in patients with hepatic dysfunction. Do not treat patients with severe hepatic impairment with ELLENCE [see Contraindications (4) ] . Reduce the starting dose for patients with less severe hepatic impairment [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3) ]. 8.7 Renal Impairment No significant alterations in the pharmacokinetics of epirubicin or its major metabolite, epirubicinol, have been observed in patients with serum creatinine <5 mg/dL. Consider lower doses in patients with severe renal impairment (serum creatinine >5 mg/dL), as a reduction in plasma clearance was reported in these patients [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3) ]. Patients on dialysis have not been studied.
