`
`WARNING: INFUSION REACTIONS, MYELOSUPPRESSION, CARDIOTOXICITY,
`LIVER IMPAIRMENT, ACCIDENTAL SUBSTITUTION
`1. The use of DOXIL (doxorubicin HCl liposome injection) may lead to cardiac toxicity.
`Myocardial damage may lead to congestive heart failure and may occur as the total
`cumulative dose of doxorubicin HCl approaches 550 mg/m2. In a clinical study in
`patients with advanced breast cancer, 250 patients received DOXIL at a starting dose of
`50 mg/m2 every 4 weeks. At all cumulative anthracycline doses between 450-500 mg/m2
`or between 500-550 mg/m2, the risk of cardiac toxicity for patients treated with DOXIL
`was 11%. Prior use of other anthracyclines or anthracenediones should be included in
`calculations of total cumulative dosage. Cardiac toxicity may also occur at lower
`cumulative doses in patients with prior mediastinal irradiation or who are receiving
`concurrent cyclophosphamide therapy [see Warnings and Precautions (5.1)].
`2. Acute infusion-related reactions including, but not limited to, flushing, shortness of
`breath, facial swelling, headache, chills, back pain, tightness in the chest or throat,
`and/or hypotension have occurred in up to 10% of patients treated with DOXIL. In
`most patients, these reactions resolve over the course of several hours to a day once the
`infusion is terminated. In some patients, the reaction has resolved with slowing of the
`infusion rate. Serious and sometimes life-threatening or fatal allergic/anaphylactoid-
`like infusion reactions have been reported. Medications to treat such reactions, as well
`as emergency equipment, should be available for immediate use. DOXIL should be
`administered at an initial rate of 1 mg/min to minimize the risk of infusion reactions
`[see Warnings and Precautions (5.2)].
`3. Severe myelosuppression may occur [see Warnings and Precautions (5.3)].
`4. Dosage should be reduced in patients with impaired hepatic function [see Dosage and
`Administration (2.6) and Use in Specific Populations (8.6)].
`5. Accidental substitution of DOXIL for doxorubicin HCl has resulted in severe side
`effects. DOXIL should not be substituted for doxorubicin HCl on a mg per mg basis
`[see Dosage and Administration (2.1)].
`
`INDICATIONS AND USAGE
`1
`1.1 Ovarian Cancer
`DOXIL (doxorubicin HCl liposome injection) is indicated for the treatment of patients with
`ovarian cancer whose disease has progressed or recurred after platinum-based chemotherapy.
`
`1.2 AIDS-Related Kaposi’s Sarcoma
`DOXIL is indicated for the treatment of AIDS-related Kaposi’s sarcoma in patients with
`disease that has progressed on prior combination chemotherapy or in patients who are intolerant
`to such therapy.
`
`
`
`2
`
`
`
`
`
`The treatment of patients with AIDS-related Kaposi’s sarcoma is based on objective tumor
`response rates. No results are available from controlled trials that demonstrate a clinical benefit
`resulting from this treatment, such as improvement in disease-related symptoms or increased
`survival.
`
`1.3 Multiple Myeloma
`DOXIL in combination with bortezomib is indicated for the treatment of patients with
`multiple myeloma who have not previously received bortezomib and have received at least one
`prior therapy.
`
`2 DOSAGE AND ADMINISTRATION
`2.1 Usage and Administration Precautions
`Liposomal encapsulation can substantially affect a drug’s functional properties relative to
`those of the unencapsulated drug. Therefore DO NOT SUBSTITUTE one drug for the other.
`
`Do not administer as a bolus injection or an undiluted solution. Rapid infusion may
`increase the risk of infusion-related reactions [see Warnings and Precautions (5.2)]. DOXIL
`must not be given by the intramuscular or subcutaneous route.
`
`Until specific compatibility data are available, it is not recommended that DOXIL be mixed
`with other drugs.
`
`DOXIL should be considered an irritant and precautions should be taken to avoid
`extravasation. With intravenous administration of DOXIL, extravasation may occur with or
`without an accompanying stinging or burning sensation, even if blood returns well on aspiration
`of the infusion needle. If any signs or symptoms of extravasation have occurred, the infusion
`should be immediately terminated and restarted in another vein. The application of ice over the
`site of extravasation for approximately 30 minutes may be helpful in alleviating the local
`reaction.
`
`2.2 Patients With Ovarian Cancer
`DOXIL (doxorubicin HCl liposome injection) should be administered intravenously at a
`dose of 50 mg/m2 (doxorubicin HCl equivalent) at an initial rate of 1 mg/min to minimize the
`risk of infusion reactions. If no infusion-related adverse reactions are observed, the rate of
`infusion can be increased to complete administration of the drug over one hour. The patient
`should be dosed once every 4 weeks, for as long as the patient does not progress, shows no
`evidence of cardiotoxicity [see Warnings and Precautions (5.1)], and continues to tolerate
`treatment. A minimum of 4 courses is recommended because median time to response in clinical
`trials was 4 months. To manage adverse reactions such as hand-foot syndrome (HFS), stomatitis,
`
`
`
`3
`
`
`
`
`or hematologic toxicity the doses may be delayed or reduced [see Dosage and Administration
`(2.5)]. Pretreatment with or concomitant use of antiemetics should be considered.
`
`2.3 Patients With AIDS-Related Kaposi’s Sarcoma
`DOXIL (doxorubicin HCl liposome injection) should be administered intravenously at a
`dose of 20 mg/m2 (doxorubicin HCl equivalent). An initial rate of 1 mg/min should be used to
`minimize the risk of infusion-related reactions. If no infusion-related adverse reactions are
`observed, the infusion rate should be increased to complete the administration of the drug over
`one hour. The dose should be repeated once every three weeks, for as long as patients respond
`satisfactorily and tolerate treatment.
`
`2.4 Patients With Multiple Myeloma
`Bortezomib is administered at a dose of 1.3 mg/m2 as intravenous bolus on days 1, 4 , 8 and
`11, every three weeks. DOXIL 30 mg/m2 should be administered as a 1-hr intravenous infusion
`on day 4 following bortezomib. With the first DOXIL dose, an initial rate of 1 mg/min should be
`used to minimize the risk of infusion-related reactions. If no infusion-related adverse reactions
`are observed, the infusion rate should be increased to complete the administration of the drug
`over one hour. Patients may be treated for up to 8 cycles until disease progression or the
`occurrence of unacceptable toxicity.
`
`2.5 Dose Modification Guidelines
`DOXIL exhibits nonlinear pharmacokinetics at 50 mg/m2; therefore, dose adjustments may
`result in a non-proportional greater change in plasma concentration and exposure to the drug
`[see Clinical Pharmacology (12.3)].
`
`Patients should be carefully monitored for toxicity. Adverse reactions, such as HFS,
`hematologic toxicities, and stomatitis may be managed by dose delays and adjustments.
`Following the first appearance of a Grade 2 or higher adverse reactions, the dosing should be
`adjusted or delayed as described in the following tables. Once the dose has been reduced, it
`should not be increased at a later time.

`adjustments in patients with neuropathic
`pain.
`
`2.6 Patients With Impaired Hepatic Function
`Limited clinical experience exists in treating patients with hepatic impairment with
`DOXIL. Based on experience with doxorubicin HCl, it is recommended that the DOXIL dosage
`be reduced if the bilirubin is elevated as follows: serum bilirubin 1.2 to 3.0 mg/dL - give ½
`normal dose; serum bilirubin > 3 mg/dL - give ¼ normal dose.
`
`No information, including dosage adjustments, is available for patients with multiple
`myeloma with hepatic impairment.
`
`2.7 Preparation for Intravenous Administration
`Each 10-mL vial contains 20 mg doxorubicin HCl at a concentration of 2 mg/mL.
`
`Each 30-mL vial contains 50 mg doxorubicin HCl at a concentration of 2 mg/mL.
`
`DOXIL doses up to 90 mg must be diluted in 250 mL of 5% Dextrose Injection, USP prior
`to administration. Doses exceeding 90 mg should be diluted in 500 mL of 5% Dextrose Injection,
`USP prior to administration. Aseptic technique must be strictly observed since no preservative or
`bacteriostatic agent is present in DOXIL. Diluted DOXIL should be refrigerated at 2°C to
`8°C (36°F to 46°F) and administered within 24 hours.
`
`Do not use with in-line filters.
`
`Do not mix with other drugs.
`
`
`
`7
`
`
`
`
`
`Do not use with any diluent other than 5% Dextrose Injection.
`
`Do not use any bacteriostatic agent, such as benzyl alcohol.
`
`DOXIL is not a clear solution but a translucent, red liposomal dispersion.
`
`Parenteral drug products should be inspected visually for particulate matter and
`discoloration prior to administration, whenever solution and container permit. Do not use if a
`precipitate or foreign matter is present.
`
`Rapid flushing of the infusion line should be avoided.
`
`2.8 Procedure for Proper Handling and Disposal
`Caution should be exercised in the handling and preparation of DOXIL.
`
`The use of gloves is required.
`
`If DOXIL comes into contact with skin or mucosa, immediately wash thoroughly with soap
`and water.
`
`DOXIL should be considered an irritant and precautions should be taken to avoid
`extravasation. With intravenous administration of DOXIL, extravasation may occur with or
`without an accompanying stinging or burning sensation, even if blood returns well on aspiration
`of the infusion needle. If any signs or symptoms of extravasation have occurred, the infusion
`should be immediately terminated and restarted in another vein. DOXIL must not be given by
`the intramuscular or subcutaneous route.
`
`DOXIL should be handled and disposed of in a manner consistent with other anticancer drugs.
`Several guidelines on this subject exist [see References (15)].
`
`3 DOSAGE FORMS AND STRENGTHS
`• 20 mg/10 mL single use vial
`• 50 mg/30 mL single use vial
`4 CONTRAINDICATIONS
`DOXIL (doxorubicin HCl liposome injection) is contraindicated in patients who have a
`history of hypersensitivity reactions to a conventional formulation of doxorubicin HCl or the
`components of DOXIL [see Warnings and Precautions (5.2)].
`
`DOXIL is contraindicated in nursing mothers [see Use in Specific Populations (8.3)].
`
`
`

`
`
`
`
`5 WARNINGS AND PRECAUTIONS
`5.1 Cardiac Toxicity
`Special attention must be given to the risk of myocardial damage from cumulative doses of
`doxorubicin HCl. Acute left ventricular failure may occur with doxorubicin, particularly in
`patients who have received a total cumulative dosage of doxorubicin exceeding the currently
`recommended limit of 550 mg/m2. Lower (400 mg/m2) doses appear to cause heart failure in
`patients who have received radiotherapy to the mediastinal area or concomitant therapy with
`other potentially cardiotoxic agents such as cyclophosphamide.
`
`Prior use of other anthracyclines or anthracenodiones should be included in calculations of
`total cumulative dosage. Congestive heart failure or cardiomyopathy may be encountered after
`discontinuation of anthracycline therapy. Patients with a history of cardiovascular disease should
`be administered DOXIL only when the potential benefit of treatment outweighs the risk.
`
`Cardiac function should be carefully monitored in patients treated with DOXIL. The most
`definitive test for anthracycline myocardial injury is endomyocardial biopsy. Other methods,
`such as echocardiography or multigated radionuclide scans, have been used to monitor cardiac
`function during anthracycline therapy. Any of these methods should be employed to monitor
`potential cardiac toxicity in patients treated with DOXIL. If these test results indicate possible
`cardiac injury associated with DOXIL therapy, the benefit of continued therapy must be carefully
`weighed against the risk of myocardial injury.
`
`In a clinical study in patients with advanced breast cancer, 250 patients received DOXIL at
`starting dose of 50 mg/m2 every 4 weeks. At all cumulative anthracycline doses between
`450-500 mg/m2, or between 500–550 mg/m2, the risk of cardiac toxicity for patients treated with
`DOXIL was 11%. In this study, cardiotoxicity was defined as a decrease of >20% from baseline
`if the resting left ventricular ejection fraction (LVEF) remained in the normal range, or a
`decrease of >10% if the resting LVEF became abnormal (less than the institutional lower limit of
`normal). The data on left ventricular ejection fraction (LVEF) defined cardiotoxicity and
`congestive heart failure (CHF) are in the table below.

`
`failure, acute pulmonary edema and pulmonary edema) was similar in the DOXIL+bortezomib
`group and the bortezomib monotherapy group, 3% in each group. LVEF decrease was defined as
`an absolute decrease of ≥15% over baseline or a ≥5% decrease below the institutional lower limit
`of normal. Based on this definition, 25 patients in the bortezomib arm (8%) and 42 patients in
`the DOXIL + bortezomib arm (13%) experienced a reduction in LVEF.
`
`5.2
`
`Infusion Reactions
`Acute infusion-related reactions were reported in 7.1% of patients treated with DOXIL in
`the randomized ovarian cancer study. These reactions were characterized by one or more of the
`following symptoms: 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. In most patients, these reactions resolve over the
`course of several hours to a day once the infusion is terminated. In some patients, the reaction
`resolved when the rate of infusion was slowed. In this study, two patients treated with DOXIL
`(0.8%) discontinued due to infusion-related reactions. In clinical studies, six patients with
`AIDS-related Kaposi’s sarcoma (0.9%) and 13 (1.7%) solid tumor patients discontinued DOXIL
`therapy because of infusion-related reactions.
`
`Serious and sometimes life-threatening or fatal allergic/anaphylactoid-like infusion
`reactions have been reported. Medications to treat such reactions, as well as emergency
`equipment, should be available for immediate use.
`
`The majority of infusion-related events occurred during the first infusion. Similar reactions
`have not been reported with conventional doxorubicin and they presumably represent a reaction
`to the DOXIL liposomes or one of its surface components.
`
`The initial rate of infusion should be 1 mg/min to help minimize the risk of infusion
`reactions [see Dosage and Administration (2)].
`
`5.3 Myelosuppression
`Because of the potential for bone marrow suppression, careful hematologic monitoring is
`required during use of DOXIL, including white blood cell, neutrophil, platelet counts, and
`Hgb/Hct. With the recommended dosage schedule, leukopenia is usually transient. Hematologic
`toxicity may require dose reduction or delay or suspension of DOXIL therapy. Persistent severe
`myelosuppression may result in superinfection, neutropenic fever, or hemorrhage. Development
`of sepsis in the setting of neutropenia has resulted in discontinuation of treatment and, in rare
`cases, death.
`
`
`
`10
`
`
`
`
`
`DOXIL may potentiate the toxicity of other anticancer therapies. In particular, hematologic
`toxicity may be more severe when DOXIL is administered in combination with other agents that
`cause bone marrow suppression.
`
`In patients with relapsed ovarian cancer, myelosuppression was generally moderate and
`reversible. In the three single-arm studies, anemia was the most common hematologic adverse
`reaction (52.6%), followed by leukopenia (WBC< 4,000 mm3; 42.2%), thrombocytopenia
`(24.2%), and neutropenia (ANC <1,000; 19.0%). In the randomized study, anemia was the most
`common hematologic adverse reaction (40.2%), followed by leukopenia (WBC <4,000 mm3;
`36.8%), neutropenia (ANC <1,000; 35.1%), and thrombocytopenia (13.0%) [see Adverse
`Reactions (6.2)].
`
`In patients with relapsed ovarian cancer, 4.6% received G-CSF (or GM-CSF) to support
`their blood counts [see Dosage and Administrations (2.5)].
`
`For patients with AIDS-related Kaposi’s sarcoma who often present with baseline
`myelosuppression due to such factors as their HIV disease or concomitant medications,
`myelosuppression appears to be the dose-limiting adverse reaction at the recommended dose of
`20 mg/m2 [see Adverse Reactions (6.2)]. Leukopenia is the most common adverse reaction
`experienced in this population; anemia and thrombocytopenia can also be expected. Sepsis
`occurred in 5% of patients; for 0.7% of patients the event was considered possibly or probably
`related to DOXIL. Eleven patients (1.6%) discontinued study because of bone marrow
`suppression or neutropenia.
`
`Table 10 presents data on myelosuppression in patients with multiple myeloma receiving
`DOXIL and bortezomib in combination [see Adverse Reactions (6.2)].
`
`5.4 Hand-Foot Syndrome (HFS)
`In the randomized ovarian cancer study, 50.6% of patients treated with DOXIL at 50
`mg/m2 every 4 weeks experienced HFS (developed palmar-plantar skin eruptions characterized
`by swelling, pain, erythema and, for some patients, desquamation of the skin on the hands and
`the feet), with 23.8% of the patients reporting HFS Grade 3 or 4 events. Ten subjects (4.2%)
`discontinued treatment due to HFS or other skin toxicity. HFS toxicity grades are described
`above [see definitions of HFS grades in Dosage and Administration (2.5)].
`
`Among 705 patients with AIDS-related Kaposi’s sarcoma treated with DOXIL at
`20 mg/m2 every 2 weeks, 24 (3.4%) developed HFS, with 3 (0.9%) discontinuing.
`
`In the randomized multiple myeloma study, 19% of patients treated with DOXIL at 30
`mg/m2 every three weeks experienced HFS.
`
`
`
`11
`
`
`
`
`
`HFS was generally observed after 2 or 3 cycles of treatment but may occur earlier. In most
`patients the reaction is mild and resolves in one to two weeks so that prolonged delay of therapy
`need not occur. However, dose modification may be required to manage HFS [see Dosage and
`Administration (2.5)]. The reaction can be severe and debilitating in some patients and may
`require discontinuation of treatment.
`
`5.5 Radiation Recall Reaction
`Recall reaction has occurred with DOXIL administration after radiotherapy.
`
`5.6 Fetal Mortality
`Pregnancy Category D
`
`DOXIL can cause fetal harm when administered to a pregnant woman. There are no
`adequate and well-controlled studies in pregnant women. If DOXIL is to be used during
`pregnancy, or if the patient becomes pregnant during therapy, the patient should be apprised of
`the potential hazard to the fetus. If pregnancy occurs in the first few months following treatment
`with DOXIL, the prolonged half-life of the drug must be considered. Women of childbearing
`potential should be advised to avoid pregnancy during treatment with Doxil. [see Use in Specific
`Populations (8.1)].
`
`5.7 Toxicity Potentiation
`The doxorubicin in DOXIL may potentiate the toxicity of other anticancer therapies.
`Exacerbation of cyclophosphamide-induced hemorrhagic cystitis and enhancement of the
`hepatotoxicity of 6-mercaptopurine have been reported with the conventional formulation of
`doxorubicin HCl. Radiation-induced toxicity to the myocardium, mucosae, skin, and liver have
`been reported to be increased by the administration of doxorubicin HCl.
`
`5.8 Monitoring: Laboratory Tests
`Complete blood counts, including platelet counts, should be obtained frequently and at a
`minimum prior to each dose of DOXIL [see Warnings and Precautions (5.3)].

`6 ADVERSE REACTIONS
`6.1 Overall Adverse Reactions Profile
`The following adverse reactions are discussed in more detail in other sections of the
`labeling.
`
`• Cardiac Toxicity [see Warnings and Precautions (5.1)]

`
`
`
`
`
`• Hand-Foot syndrome [see Warnings and Precautions (5.4)]
`The most common adverse reactions observed with DOXIL are asthenia, fatigue, fever,
`nausea, stomatitis, vomiting, diarrhea, constipation, anorexia, hand-foot syndrome, rash and
`neutropenia, thrombocytopenia and anemia.
`
`The most common serious adverse reactions observed with DOXIL are described in
`Section 6.2.
`
`The safety data described below reflect exposure to DOXIL in 1310 patients including:
`239 patients with ovarian cancer, 753 patients with AIDS-related Kaposi’s sarcoma and
`318 patients with multiple myeloma [see Adverse Reactions in Clinical Trials (6.2)].
`
`6.2 Adverse Reactions in Clinical Trials
`Because clinical trials are conducted under widely varying conditions, the adverse reaction
`rates observed cannot be directly compared to rates on other clinical trials and may not reflect the
`rates observed in clinical practice.
`
`The following tables present adverse reactions from clinical trials of DOXIL in ovarian
`cancer and AIDS-Related Kaposi’s sarcoma.
`
`Patients With Ovarian Cancer
`The safety data described below are from 239 patients with ovarian cancer treated with
`DOXIL (doxorubicin HCl liposome injection) at 50 mg/m2 once every 4 weeks for a minimum
`of 4 courses in a randomized, multicenter, open-label study. In this study, patients received
`DOXIL for a median number of 98.0 days (range 1-785 days). The population studied was 27-87
`years of age, 91% Caucasian, 6% Black and 3% Hispanic a
