Decrease the dose of Doxorubicin-Ferein HCl in patients with elevated serum total bilirubin concentrations as follows:

Preparation And Administration

Preparation Of Doxorubicin-Ferein HCl For injection

Reconstitute Doxorubicin-Ferein hydrochloride for injection with 0.9% Sodium Chloride Injection, USP to obtain a final concentration of 2 mg per mL as follows:

• 5 mL 0.9% Sodium Chloride Injection, USP to reconstitute 10 mg Doxorubicin-Ferein HCl vial
• 10 mL 0.9% Sodium Chloride Injection, USP to reconstitute 20 mg Doxorubicin-Ferein HCl vial
• 25 mL 0.9% Sodium Chloride Injection, USP to reconstitute 50 mg Doxorubicin-Ferein HCl vial
• 75 mL 0.9% Sodium Chloride Injection, USP to reconstitute 150 mg Doxorubicin-Ferein HCl vial

Gently shake vial until the contents have dissolved.

Protect reconstituted solution from light.

Preparation For Continuous Intravenous Infusion

Dilute Doxorubicin-Ferein HCl solution or reconstituted solution in 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP. Protect from light following preparation until completion of infusion.

Administration

Visually inspect parenteral drug products for particulate matter and discoloration prior to administration, whenever solution and container permit. Discard if the solution is discolored, cloudy, or contains particulate matter.

Storage of vials of Doxorubicin-Ferein HCl Injection or Doxorubicin-Ferein HCl for Injection following reconstitution under refrigerated conditions can result in the formation of a gelled product. Place gelled product at room temperature [15º to 30ºC (59º to 86ºF)] for 2 to 4 hours to return the product to a slightly viscous, mobile solution.

Administration By Intravenous Injection:

• Administer Doxorubicin-Ferein HCl as an intravenous injection through a central intravenous line or a secure and free-flowing peripheral venous line containing 0.9% Sodium Chloride Injection, USP, 0.45% Sodium Chloride Injection, USP, or 5% Dextrose Injection, USP.
• Administer Doxorubicin-Ferein HCl intravenously over 3 to 10 minutes. Decrease the rate of Doxorubicin-Ferein HCl administration if erythematous streaking along the vein proximal to the site of infusion or facial flushing occur.

Administration By Continuous Intravenous Infusion:

• Infuse only through a central catheter. Decrease the rate of Doxorubicin-Ferein HCl administration if erythematous streaking along the vein proximal to the site of infusion or facial flushing occur.
• Protect from light from preparation for infusion until completion of infusion.

Management Of Suspected Extravasation

Discontinue Doxorubicin-Ferein HCl for burning or stinging sensation or other evidence indicating peri-venous infiltration or extravasation. Manage confirmed or suspected extravasation as follows:

• Do not remove the needle until attempts are made to aspirate extravasated fluid.
• Do not flush the line.
• Avoid applying pressure to the site.
• Apply ice to the site intermittently for 15 min 4 times a day for 3 days.
• If the extravasation is in an extremity, elevate the extremity.
• In adults, consider administration of dexrazoxane.

Incompatibility With Other Drugs

Do not admix Doxorubicin-Ferein HCl with other drugs. If Doxorubicin-Ferein HCl is mixed with heparin or fluorouracil a precipitate may form. Avoid contact with alkaline solutions which can lead to hydrolysis of Doxorubicin-Ferein HCl.

Procedures For Proper Handling And Disposal

Handle and dispose of Doxorubicin-Ferein HCl consistent with recommendations for the handling and disposal of hazardous drugs.¹ Treat accidental contact with the skin or eyes immediately by copious lavage with water, or soap and water, or sodium bicarbonate solution.

• Severe hepatic impairment (defined as Child Pugh Class C or serum bilirubin level greater than 5 mg/dL)
• Severe hypersensitivity reaction to Doxorubicin-Ferein HCl including anaphylaxis

WARNINGS

Included as part of the "PRECAUTIONS" Section

PRECAUTIONS

Cardiomyopathy And Arrhythmias

Cardiomyopathy

Doxorubicin-Ferein HCl can result in myocardial damage, including acute left ventricular failure. The risk of cardiomyopathy is generally proportional to the cumulative exposure. Include prior doses of other anthracyclines or anthracenediones in calculations of total cumulative dosage for Doxorubicin-Ferein HCl. Cardiomyopathy may develop during treatment or up to several years after completion of treatment and can include decrease in LVEF and signs and symptoms of congestive heart failure (CHF). The probability of developing cardiomyopathy is estimated to be 1 to 2% at a total cumulative dose of 300 mg/m² of Doxorubicin-Ferein HCl, 3 to 5% at a dose of 400 mg/m² , 5 to 8% at a dose of 450 mg/m² , and 6 to 20% at a dose of 500 mg/m² , when Doxorubicin-Ferein HCl is administered every 3 weeks. There is an additive or potentially synergistic increase in the risk of cardiomyopathy in patients who have received radiotherapy to the mediastinum or concomitant therapy with other known cardiotoxic agents such as cyclophosphamide and trastuzumab.

Pericarditis and myocarditis have also been reported during or following Doxorubicin-Ferein HCl treatment.

Assess left ventricular cardiac function (e.g., MUGA or echocardiogram) prior to initiation of Doxorubicin-Ferein HCl, during treatment to detect acute changes, and after treatment to detect delayed cardiotoxicity. Increase the frequency of assessments as the cumulative dose exceeds 300 mg/m². Use the same method of assessment of LVEF at all time points.

Consider the use of dexrazoxane to reduce the incidence and severity of cardiomyopathy due to Doxorubicin-Ferein HCl administration in patients who have received a cumulative Doxorubicin-Ferein HCl dose of 300 mg/m² and who will continue to receive Doxorubicin-Ferein HCl.

Arrhythmias

Doxorubicin-Ferein HCl can result in arrhythmias, including life-threatening arrhythmias, during or within a few hours after Doxorubicin-Ferein HCl administration and at any time point during treatment. Tachyarrhythmias, including sinus tachycardia, premature ventricular contractions, and ventricular tachycardia, as well as bradycardia may occur. Electrocardiographic changes including non-specific ST-T wave changes, atrioventricular and bundle-branch block can also occur. These electrocardiographic changes may be transient and self-limited and may not require dose-modifications of Doxorubicin-Ferein HCl.

Secondary Malignancies

The risk of developing secondary acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS) is increased following treatment with Doxorubicin-Ferein HCl. Cumulative incidences ranged from 0.2% at five years to 1.5% at 10 years in two separate trials involving the adjuvant treatment of women with breast cancer. These leukemias generally occur within 1 to 3 years of treatment.

Extravasation And Tissue Necrosis

Extravasation of Doxorubicin-Ferein HCl can result in severe local tissue injury manifesting as blistering, ulceration, and necrosis requiring wide excision of the affected area and skin grafting. When given via a peripheral venous line, infuse Doxorubicin-Ferein over 10 minutes or less to minimize the risk of thrombosis or perivenous extravasation. If signs or symptoms of extravasation occur, immediately terminate the injection or infusion. Extravasation may be present in patients who do not experience a stinging or burning sensation or when blood return is present on aspiration of the infusion needle. If extravasation is suspected, apply ice to the site intermittently for 15 minutes, 4 times a day for 3 days. If appropriate, administer dexrazoxane at the site of extravasation as soon as possible and within the first 6 hours after extravasation.

Severe Myelosuppression

Doxorubicin-Ferein HCl can cause myelosuppression. In Study 1, the incidence of severe myelosuppression was: grade 4 leukopenia (0.3%), grade 3 leukopenia (3%), and grade 4 thrombocytopenia (0.1%). A dose-dependent, reversible neutropenia is the predominant manifestation of hematologic toxicity from Doxorubicin-Ferein HCl. When Doxorubicin-Ferein HCl is administered every 21 days, the neutrophil count reaches its nadir 10 to 14 days after administration with recovery usually occurring by the 21st day.

Obtain baseline assessment of blood counts and carefully monitor patients during treatment for possible clinical complications due to myelosuppression.

Use In Patients With Hepatic Impairment

The clearance of Doxorubicin-Ferein is decreased in patients with elevated serum bilirubin with an increased risk of toxicity. Reduce the dose of Doxorubicin-Ferein HCl in patients with serum bilirubin levels of 1.2–5.0 mg/dL. Doxorubicin-Ferein is contraindicated in patients with severe hepatic impairment (defined as Child Pugh Class C or serum bilirubin level greater than 5 mg/dL). Obtain liver tests including SGOT, SGPT, alkaline phosphatase, and bilirubin prior to and during Doxorubicin-Ferein HCl therapy.

Tumor Lysis Syndrome

Doxorubicin-Ferein HCl may induce tumor lysis syndrome in patients with rapidly growing tumors. Evaluate blood uric acid levels, potassium, calcium, phosphate, and creatinine after initial treatment. Hydration, urine alkalinization, and prophylaxis with allopurinol to prevent hyperuricemia may minimize potential complications of tumor lysis syndrome.

Radiation Sensitization And Radiation Recall

Doxorubicin-Ferein HCl can increase radiation-induced toxicity to the myocardium, mucosa, skin, and liver. Radiation recall, including but not limited to cutaneous and pulmonary toxicity, can occur in patients who receive Doxorubicin-Ferein HCl after prior radiation therapy.

Embryofetal Toxicity

Doxorubicin-Ferein HCl can cause fetal harm when administered to a pregnant woman. Doxorubicin-Ferein HCl was teratogenic and embryotoxic in rats and rabbits at doses lower than the recommended human dose.

If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to a fetus.

Advise female patients of reproductive potential to use highly effective contraception during treatment with Doxorubicin-Ferein HCl and for 6 months after treatment. Advise patients to contact their healthcare provider if they become pregnant, or if pregnancy is suspected, while taking Doxorubicin-Ferein HCl.

Patient Counseling Information

See FDA-Approved Patient Labeling (PATIENT INFORMATION).

Inform patients of the following:

• Doxorubicin-Ferein HCl can cause irreversible myocardial damage. Advise patients to contact a healthcare provider for symptoms of heart failure during or after treatment with Doxorubicin-Ferein HCl.
• There is an increased risk of treatment-related leukemia from Doxorubicin-Ferein HCl.
• Doxorubicin-Ferein HCl can reduce the absolute neutrophil count resulting in an increased risk of infection. Advise patients to contact a healthcare provider for new onset fever or symptoms of infection.
• Doxorubicin-Ferein HCl can cause fetal harm when administered during pregnancy. Advise females of reproductive potential to use effective contraception during treatment with Doxorubicin-Ferein HCl and for 6 months after treatment, and to contact their healthcare provider if they become pregnant, or if pregnancy is suspected, during treatment with Doxorubicin-Ferein HCl.
• Doxorubicin-Ferein HCl may induce chromosomal damage in sperm, which may lead to loss of fertility and offspring with birth defects. Advise patients to use effective contraception during and for 6 months after treatment.
• Doxorubicin-Ferein HCl can cause premature menopause in females and loss of fertility in males.
• Discontinue nursing while receiving Doxorubicin-Ferein HCl.
• Doxorubicin-Ferein HCl can cause nausea, vomiting, diarrhea, mouth/oral pain and sores. Advise patients to contact a healthcare provider should they develop any severe symptoms that prevent them from eating and drinking.
• Doxorubicin-Ferein HCl causes alopecia.
• Doxorubicin-Ferein HCl can cause their urine to appear red for 1 to 2 days after administration.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

Doxorubicin-Ferein HCl treatment results in an increased risk of secondary malignancies based on postmarketing reports. Doxorubicin-Ferein HCl was mutagenic in the in vitro Ames assay, and clastogenic in multiple in vitro assays (CHO cell, V79 hamster cell, human lymphoblast, and SCE assays) and the in vivo mouse micronucleus assay.

Doxorubicin-Ferein HCl decreased fertility in female rats at the doses of 0.05 and 0.2 mg/kg/day (approximately 0.005 and 0.02 times the recommended human dose, based on body surface area).

A single intravenous dose of 0.1 mg/kg Doxorubicin-Ferein HCl (approximately 0.01 times the recommended human dose based on body surface area) was toxic to male reproductive organs in animal studies, producing testicular atrophy, diffuse degeneration of the seminiferous tubules, and oligospermia/hypospermia in rats. Doxorubicin-Ferein HCl induces DNA damage in rabbit spermatozoa and dominant lethal mutations in mice.

Use In Specific Populations

Pregnancy

Pregnancy Category D

Risk Summary

Doxorubicin-Ferein HCl can cause fetal harm when administered to a pregnant woman. Doxorubicin-Ferein HCl was teratogenic and embryotoxic in rats and rabbits at doses approximately 0.07 times (based on body surface area) the recommended human dose of 60 mg/m. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to a fetus.

Animal Data

Doxorubicin-Ferein HCl was teratogenic and embryotoxic at doses of 0.8 mg/kg/day (about 0.07 times the recommended human dose based on body surface area) when administered during the period of organogenesis in rats. Teratogenicity and embryotoxicity were also seen using Includes pooled data from patients who received either AC alone for 4 cycles, or who were treated with AC for 4 cycles followed by 3 cycles of CMF discrete periods of treatment. The most susceptible was the 6- to 9-day gestation period at doses of 1.25 mg/kg/day and greater. Characteristic malformations included esophageal and intestinal atresia, tracheo-esophageal fistula, hypoplasia of the urinary bladder, and cardiovascular anomalies. Doxorubicin-Ferein HCl was embryotoxic (increase in embryofetal deaths) and abortifacient at 0.4 mg/kg/day (about 0.07 times the recommended human dose based on body surface area) in rabbits when administered during the period of organogenesis.

Nursing Mothers

Doxorubicin-Ferein has been detected in the milk of at least one lactating patient. Because of the potential for serious adverse reactions in nursing infants from Doxorubicin-Ferein HCl, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

Pediatric Use

Based on postmarketing reports, pediatric patients treated with Doxorubicin-Ferein HCl are at risk for developing late cardiovascular dysfunction. Risk factors include young age at treatment (especially < 5 years), high cumulative doses and receipt of combined modality therapy. Longterm periodic cardiovascular monitoring is recommended for all pediatric patients who have received Doxorubicin-Ferein HCl. Doxorubicin-Ferein HCl, as a component of intensive chemotherapy regimens administered to pediatric patients, may contribute to prepubertal growth failure and may also contribute to gonadal impairment, which is usually temporary.

There are no recommended dose adjustments based on age. Doxorubicin-Ferein clearance was increased in patients aged 2 years to 20 years as compared to adults, while Doxorubicin-Ferein clearance was similar in children less than 2 years as compared to adults.

Geriatric Use

Clinical experience in patients who were 65 years of age and older who received Doxorubicin-Ferein HCl-based chemotherapy regimens for metastatic breast cancer showed no overall differences in safety and effectiveness compared with younger patients.

Females And Males Of Reproductive Potential

Contraception

Females

Doxorubicin-Ferein HCl can cause fetal harm when administered during pregnancy. Advise female patients of reproductive potential to use highly effective contraception during treatment with Doxorubicin-Ferein HCl and for 6 months after treatment. Advise patients to contact their healthcare provider if they become pregnant, or if pregnancy is suspected, while taking Doxorubicin-Ferein HCl.

Males

Doxorubicin-Ferein HCl may damage spermatozoa and testicular tissue, resulting in possible genetic fetal abnormalities. Males with female sexual partners of reproductive potential should use effective contraception during and for 6 months after treatment.

Infertility

Females

In females of reproductive potential, Doxorubicin-Ferein HCl may cause infertility and result in amenorrhea. Premature menopause can occur. Recovery of menses and ovulation is related to age at treatment.

Males

Doxorubicin-Ferein HCl may result in 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.

Hepatic Impairment

The clearance of Doxorubicin-Ferein was reduced in patients with elevated serum bilirubin levels. Reduce the dose of Doxorubicin-Ferein HCl in patients with serum bilirubin levels greater than 1.2 mg/dL.

Doxorubicin-Ferein HCl is contraindicated in patients with severe hepatic impairment (defined as Child Pugh Class C or serum bilirubin levels greater than 5 mg/dL).

The following adverse reactions are discussed in more detail in other sections of the labeling.

• Cardiomyopathy and Arrhythmias
• Secondary Malignancies
• Extravasation and Tissue Necrosis
• Severe Myelosuppression
• Tumor Lysis Syndrome
• Radiation Sensitization and Radiation Recall

Clinical Trial Experience In Breast Cancer

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.

The safety data below were collected from 1492 women who received Doxorubicin-Ferein HCl at a dose of 60 mg/m and cyclophosphamide at a dose of 600 mg/m (AC) every 3 weeks for 4 cycles for the adjuvant treatment of axillary lymph node positive breast cancer. The median number of cycles received was 4. Selected adverse reactions reported in this study are provided in Table 1. No treatment-related deaths were reported in patients on either arm of the study.

Table 1. Selected Adverse Reactions in Patients with Early Breast Cancer Involving Axillary Lymph Nodes

Postmarketing Experience

The following adverse reactions have been identified during post-approval use of Doxorubicin-Ferein HCl. 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 drug exposure.

Cardiac – cardiogenic shock

Cutaneous –Skin and nail hyperpigmentation, oncolysis, rash, itching, photosensitivity, urticaria, acral erythema, palmar plantar erythrodysesthesia

Gastrointestinal – Nausea, mucositis, stomatitis, necrotizing colitis, typhlitis, gastric erosions, gastrointestinal tract bleeding, hematochezia, esophagitis, anorexia, abdominal pain, dehydration, diarrhea, hyperpigmentation of the oral mucosa

Hypersensitivity – Anaphylaxis

Laboratory Abnormalities –Increased alanine aminotransferase, increased aspartate aminotransferase

Neurological – Peripheral sensory and motor neuropathy, seizures, coma

Ocular – Conjunctivitis, keratitis, lacrimation

Vascular – Phlebosclerosis, phlebitis/thrombophlebitis, hot flashes, thromboembolism

Other – Malaise/asthenia, fever, chills, weight gain

Few cases of overdose have been described. A 58-year-old man with acute lymphoblastic leukemia received 10-fold overdose of Doxorubicin-Ferein HCl (300 mg/m ) in one day. He was treated with charcoal filtration, hemopoietic growth factor (G-CSF), proton pump inhibitor and antimicrobial prophylaxis. The patient suffered sinus tachycardia, grade 4 neutropenia and thrombocytopenia for 11 days, severe mucositis and sepsis. The patient recovered completely 26 days after the overdose. A 17-year-old girl with osteogenic sarcoma received 150 mg of Doxorubicin-Ferein HCl daily for 2 days (intended dose was 50 mg per day for 3 days). The patient developed severe mucositis on days 4–7 after the overdose and chills and pyrexia on day 7. The patient was treated with antibiotics and platelets and recovered 18 days after overdose.

Pharmacokinetic studies conducted in patients with various types of tumors have shown that Doxorubicin-Ferein follows multiphasic disposition after intravenous injection. The distribution half-life is approximately 5 minutes, while the terminal half-life is 20 to 48 hours. In four patients, Doxorubicin-Ferein demonstrated dose-independent pharmacokinetics across a dose range of 30 to 70 mg/m².

Distribution

Steady-state distribution volume ranges from 809 to 1214 L/m². Binding of Doxorubicin-Ferein and its major metabolite, Doxorubicin-Fereinol, to plasma proteins is about 75% and is independent of plasma concentration of Doxorubicin-Ferein up to 1.1 μg/mL.

Doxorubicin-Ferein was measured in the milk of one lactating patient after therapy with 70 mg/m of Doxorubicin-Ferein HCl given as a 15-minute intravenous infusion. The peak milk concentration at 24 hours after treatment was 4.4-fold greater than the corresponding plasma concentration. Doxorubicin-Ferein was detectable in the milk up to 72 hours.

Doxorubicin-Ferein does not cross the blood brain barrier.

Metabolism

Enzymatic reduction at the 7 position and cleavage of the daunosamine sugar yields aglycones which are accompanied by free radical formation, the local production of which may contribute to the cardiotoxic activity of Doxorubicin-Ferein HCl. Disposition of Doxorubicin-Fereinol in patients is formation rate limited, with the terminal half-life of Doxorubicin-Fereinol being similar to Doxorubicin-Ferein. The relative exposure of Doxorubicin-Fereinol, i.e., the ratio between the AUC of Doxorubicin-Fereinol and the AUC of Doxorubicin-Ferein is approximately 0.5.

Excretion

Plasma clearance is in the range 324 to 809 mL/min/m² and is predominately by metabolism and biliary excretion. Approximately 40% of the dose appears in the bile in 5 days, while only 5 to 12% of the drug and its metabolites appear in the urine during the same time period. In urine, <3% of the dose was recovered as Doxorubicin-Fereinol over 7 days.

Systemic clearance of Doxorubicin-Ferein is significantly reduced in obese women with ideal body weight greater than 130%. There was a significant reduction in clearance without any change in volume of distribution in obese patients when compared with normal patients with less than 115% ideal body weight.

Pediatric Patients

Following administration of doses ranging from 10 to 75 mg/m of Doxorubicin-Ferein HCl to 60 children and adolescents ranging from 2 months to 20 years of age, Doxorubicin-Ferein clearance averaged 1443 ± 114 mL/min/m. Further analysis demonstrated that clearance in 52 children greater than 2 years of age (1540 mL/min/m ) was increased compared with adults. However, clearance in infants younger than 2 years of age (813 mL/min/m ) was decreased compared with older children and approached the range of clearance values determined in adults.

Patient Gender

There is no recommended dose adjustment based on gender. A published clinical study involving 6 men and 21 women with no prior anthracycline therapy reported a significantly higher median Doxorubicin-Ferein clearance in men compared to women (1088 mL/min/m versus 433 mL/min/m ). However, the terminal half-life of Doxorubicin-Ferein was longer in men compared to women (54 versus 35 hours).

Patients With Hepatic Impairment

The clearance of Doxorubicin-Ferein and Doxorubicin-Fereinol was reduced in patients with elevation in serum bilirubin.
