5 WARNINGS AND PRECAUTIONS Hand-Foot Syndrome may occur. Dose modification or discontinuation may be required ( 5.3 ) Embryo-Fetal Toxicity: Can cause fetal harm. Advise of potential risk to a fetus. Use effective contraception ( 5.5 , 8.1 , 8.3 ) 5.1 Cardiomyopathy Doxorubicin hydrochloride can cause myocardial damage, including acute left ventricular failure. The risk of cardiomyopathy with doxorubicin hydrochloride is generally proportional to the cumulative exposure. Include prior use of other anthracyclines or anthracenediones in calculations of cumulative dose. The risk of cardiomyopathy may be increased at lower cumulative doses in patients with prior mediastinal irradiation. In a clinical study in 250 patients with advanced cancer who were treated with doxorubicin hydrochloride liposome injection, the risk of cardiomyopathy was 11% when the cumulative anthracycline dose was between 450 mg/m 2 to 550 mg/m 2 . Cardiomyopathy was defined as >20% decrease in resting left ventricular ejection fraction (LVEF) from baseline where LVEF remained in the normal range or a >10% decrease in LVEF from baseline where LVEF was less than the institutional lower limit of normal. Two percent of patients developed signs and symptoms of congestive heart failure without documented evidence of cardiomyopathy. Assess left ventricular cardiac function (e.g. MUGA or echocardiogram) prior to initiation of doxorubicin hydrochloride liposome injection, during treatment to detect acute changes, and after treatment to detect delayed cardiomyopathy. Administer doxorubicin hydrochloride liposome injection to patients with a history of cardiovascular disease only when the potential benefit of treatment outweighs the risk. 5.2 Infusion-Related Reactions Serious, life-threatening, and fatal infusion-related reactions characterized by one or more of the following symptoms can occur with doxorubicin hydrochloride liposome injection: flushing, shortness of breath, facial swelling, headache, chills, chest pain, back pain, tightness in the chest and throat, fever, tachycardia, pruritus, rash, cyanosis, syncope, bronchospasm, asthma, apnea, and hypotension. Of 239 patients with ovarian cancer treated with doxorubicin hydrochloride liposome injection in Trial 4, 7% of patients experienced acute infusion-related reactions resulting in dose interruption. All occurred during cycle 1 and none during subsequent cycles. Across multiple studies of doxorubicin hydrochloride liposome injection monotherapy including this and other studies enrolling 760 patients with various solid tumors, 11% of patients had infusion-related reactions. The majority of infusion-related events occurred during the first infusion. Ensure that medications to treat infusion-related reactions and cardiopulmonary resuscitative equipment are available for immediate use prior to initiation of doxorubicin hydrochloride liposome injection. Initiate doxorubicin hydrochloride liposome injection infusions at a rate of 1 mg/min and increase rate as tolerated [see Dosage and Administration (2.6)]. Withhold doxorubicin hydrochloride liposome injection for Grade 1, 2, or 3 infusion-related reactions and resume at a reduced infusion rate. Discontinue doxorubicin hydrochloride liposome injection for serious or life-threatening infusion-related reactions. 5.3 Hand-Foot Syndrome(HFS) In Trial 4, the incidence of HFS was 51% of patients in the doxorubicin hydrochloride liposome injection arm and 0.9% of patients in the topotecan arm, including 24% Grade 3 or 4 cases of HFS in doxorubicin hydrochloride liposome injection-treated patients and no Grade 3 or 4 cases in topotecan-treated patients. HFS or other skin toxicity required discontinuation of doxorubicin hydrochloride liposome injection in 4.2% of patients. HFS was generally observed after 2 or 3 cycles of treatment but may occur earlier. Delay doxorubicin hydrochloride liposome injection for the first episode of Grade 2 or greater HFS [ see Dosage and Admin…

4 CONTRAINDICATIONS Doxorubicin hydrochloride liposome injection is contraindicated in patients who have a history of severe hypersensitivity reactions, including anaphylaxis, to doxorubicin hydrochloride [see Warnings and Precautions (5.2)]. Hypersensitivity reactions to doxorubicin hydrochloride or the components of doxorubicin hydrochloride liposome injection ( 4 , 5.2 )

7 DRUG INTERACTIONS No formal drug interaction studies have been conducted with doxorubicin hydrochloride liposome injection.

8.1 Pregnancy Risk Summary Based on findings in animals and its mechanism of action, doxorubicin hydrochloride liposome injection can cause fetal harm when administered to a pregnant woman; avoid the use of doxorubicin hydrochloride liposome injection during the 1 st trimester. In animal reproduction studies, doxorubicin hydrochloride liposome injection was embryotoxic in rats and abortifacient in rabbits following intravenous administration during organogenesis at doses approximately 0.12 times the recommended clinical dose (see Data). Available human data do not establish the presence or absence of major birth defects and miscarriage related to the use of doxorubicin hydrochloride during the 2 nd and 3 rd trimesters. Advise pregnant women of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated populations are unknown. However, the background risk in the U.S. general population of major birth defects is 2 to 4% and of miscarriage is 15 to 20% of clinically recognized pregnancies. Data Animal Data Doxorubicin hydrochloride liposome injection was embryotoxic at doses of 1 mg/kg/day in rats and was embryotoxic and abortifacient at 0.5 mg/kg/day in rabbits (both doses are about 0.12 times the recommended dose of 50 mg/m 2 human dose on a mg/m 2 basis). Embryotoxicity was characterized by increased embryo-fetal deaths and reduced live litter sizes.
