Doxorubicin pegylated liposomal SUN should only be administered under the supervision of a qualified oncologist specialised in the administration of cytotoxic agents. Doxorubicin pegylated liposomal SUN exhibits unique pharmacokinetic properties and must not be used interchangeably with other formulations of doxorubicin hydrochloride.
Posology Breast cancer/Ovarian cancer Doxorubicin pegylated liposomal SUN is administered intravenously at a dose of 50 mg/m2 once every 4 weeks for as long as the disease does not progress and the patient continues to tolerate treatment.
Multiple myeloma Doxorubicin pegylated liposomal SUN is administered at 30 mg/m² on day 4 of the bortezomib 3 week regimen as a 1 hour infusion administered immediately after the bortezomib infusion. 3 mg/m² on days 1, 4, 8, and 11 every 3 weeks.
The dose should be repeated as long as patients respond satisfactorily and tolerate treatment. Day 4 dosing of both medicinal products may be delayed up to 48 hours as medically necessary. Doses of bortezomib should be at least 72 hours apart.
AIDS-related KS Doxorubicin pegylated liposomal SUN is administered intravenously at 20 mg/m2 every two- to-three weeks. Avoid intervals shorter than 10 days as medicinal product accumulation and increased toxicity cannot be ruled out.
Treatment of patients for two-to-three months is recommended to achieve a therapeutic response. Continue treatment as needed to maintain a therapeutic response. 8), immediately discontinue the infusion, give appropriate premedications (antihistamine and/or short acting corticosteroid) and restart at a slower rate.
Guidelines for Doxorubicin pegylated liposomal SUN dose modification To manage adverse events such as palmar-plantar erythrodysesthesia (PPE), stomatitis or haematological toxicity, the dose may be reduced or delayed. Guidelines for Doxorubicin pegylated liposomal SUN dose modification secondary to these adverse effects are provided in the tables below.
The toxicity grading in these tables is based on the National Cancer Institute Common Toxicity Criteria (NCI-CTC). The tables for PPE (Table 1) and stomatitis (Table 2) provide the schedule followed for dose modification in clinical trials in the treatment of breast or ovarian cancer (modification of the recommended 4 week treatment cycle): if these toxicities occur in patients with AIDS-related KS, the recommended 2 to 3 week treatment cycle can be modified in a similar manner.
Summary of the safety profile The most frequent adverse reactions (≥ 20%) were neutropaenia, nausea, leukopaenia, anaemia, and fatigue. Severe adverse reactions (Grade 3/4 adverse reactions occurring in ≥ 2% of patients) were neutropaenia, PPE, leukopaenia, lymphopaenia, anaemia, thrombocytopaenia, stomatitis, fatigue, diarrhoea, vomiting, nausea, pyrexia, dyspnoea, and pneumonia.
Less frequently reported severe adverse reactions included Pneumocystis jirovecii pneumonia, abdominal pain, cytomegalovirus infection including cytomegalovirus chorioretinitis, asthenia, cardiac arrest, cardiac failure, cardiac failure congestive, pulmonary embolism, thrombophlebitis, venous thrombosis, anaphylactic reaction, anaphylactoid reaction, toxic epidermal necrolysis, and Stevens-Johnson syndrome.
Tabulated list of adverse reactions Table 5 summarises the adverse drug reactions that occurred in patients receiving doxorubicin pegylated liposomal in 4,231 patients for the treatment of breast cancer, ovarian cancer, multiple myeloma, and AIDS-related KS.
Post- marketing adverse reactions are also included, as indicated by “b”. Frequencies are defined as very common (≥ 1/10), common (≥ 1/100 to < 1/10), uncommon (≥ 1/1,000 to < 1/100), rare (≥ 1/10,000 to < 1/1,000), very rare (< 1/10,000) and not known (frequency cannot be estimated from the available data).
Within each frequency grouping, where relevant, adverse reactions are presented in order of decreasing seriousness. Table
Given the difference in pharmacokinetic profiles and dosing schedules, Doxorubicin pegylated liposomal SUN should not be used interchangeably with other formulations of doxorubicin hydrochloride. Cardiac toxicity It is recommended that all patients receiving Doxorubicin pegylated liposomal SUN routinely undergo frequent ECG monitoring.
Transient ECG changes such as T-wave flattening, S-T segment depression and benign arrhythmias are not considered mandatory indications for the suspension of Doxorubicin pegylated liposomal SUN therapy. However, reduction of the QRS complex is considered more indicative of cardiac toxicity.
, endomyocardial biopsy, must be considered. More specific methods for the evaluation and monitoring of cardiac functions as compared to ECG are a measurement of left ventricular ejection fraction by echocardiography or preferably by Multigated Angiography (MUGA).
These methods must be applied routinely before the initiation of Doxorubicin pegylated liposomal SUN therapy and repeated periodically during treatment. The evaluation of left ventricular function is considered to be mandatory before each additional administration of Doxorubicin pegylated liposomal SUN that exceeds a lifetime cumulative anthracycline dose of 450 mg/m2.
The evaluation tests and methods mentioned above concerning the monitoring of cardiac performance during anthracycline therapy are to be employed in the following order: ECG monitoring, measurement of left ventricular ejection fraction, endomyocardial biopsy.
If a test result indicates possible cardiac injury associated with Doxorubicin pegylated liposomal SUN therapy, the benefit of continued therapy must be carefully weighed against the risk of myocardial injury. In patients with cardiac disease requiring treatment, administer Doxorubicin pegylated liposomal SUN only when the benefit outweighs the risk to the patient.
3. 1. 0 and an osmolality of 320-380 mOsm/kg. 1 Therapeutic indications Doxorubicin pegylated liposomal SUN is indicated: - As monotherapy for patients with metastatic breast cancer, where there is an increased cardiac risk. - For treatment of advanced ovarian cancer in women who have failed a first- line platinum-based chemotherapy regimen.
- In combination with bortezomib for the treatment of progressive multiple myeloma in patients who have received at least one prior therapy and who have already undergone or are unsuitable for bone marrow transplant. - -For treatment of AIDS-related Kaposi’s sarcoma (KS) in patients with low CD4 counts (< 200 CD4 lymphocytes/mm3) and extensive mucocutaneous or visceral disease.
Doxorubicin pegylated liposomal SUN may be used as first-line systemic chemotherapy, or as second line chemotherapy in AIDS-KS patients with disease that has progressed with, or in patients intolerant to, prior combination systemic chemotherapy comprising at least two of the following agents: a vinca alkaloid, bleomycin and standard doxorubicin (or other anthracycline).

Exercise caution in patients with impaired cardiac function who receive Doxorubicin pegylated liposomal SUN. , < 45%), endomyocardial biopsy may be considered and the benefit of continued therapy must be carefully evaluated against the risk of developing irreversible cardiac damage.
Congestive heart failure due to cardiomyopathy may occur suddenly, without prior ECG changes and may also be encountered several weeks after discontinuation of therapy. Caution must be observed in patients who have received other anthracyclines.
, 5-fluorouracil. Cardiac toxicity also may occur at cumulative anthracycline doses lower than 450 mg/m2 in patients with prior mediastinal irradiation or in those receiving concurrent cyclophosphamide therapy. 8). Myelosuppression Many patients treated with Doxorubicin pegylated liposomal SUN have baseline myelosuppression due to such factors as their pre-existing HIV disease or numerous concomitant or previous medications, or tumours involving bone marrow.
In the pivotal trial in patients with ovarian cancer treated at a dose of 50 mg/m2, myelosuppression was generally mild to moderate, reversible, and was not associated with episodes of neutropaenic infection or sepsis. Moreover, in a controlled clinical trial of liposomal doxorubicin vs.
topotecan, the incidence of treatment related sepsis was substantially less in the liposomal doxorubicin-treated ovarian cancer patients as compared to the topotecan treatment group. A similar low incidence of myelosuppression was seen in patients with metastatic breast cancer receiving liposomal doxorubicin in a first-line clinical trial.
8). Because of the potential for bone marrow suppression, periodic blood counts must be performed frequently during the course of Doxorubicin pegylated liposomal SUN therapy, and at a minimum, prior to each dose of Doxorubicin pegylated liposomal SUN.
Persistent severe myelosuppression, may result in superinfection or haemorrhage. In controlled clinical studies in patients with AIDS-KS against a bleomycin/vincristine regimen, opportunistic infections were apparently more frequent during treatment with liposomal doxorubicin.
Patients and doctors must be aware of this higher incidence and take action as appropriate. Secondary haematological malignancies As with other DNA-damaging antineoplastic agents, secondary acute myeloid leukemias and myelodysplasias have been reported in patients having received combined treatment with doxorubicin.
Therefore, any patient treated with doxorubicin should be kept under haematological supervision. Secondary oral neoplasms Very rare cases of secondary oral cancer have been reported in patients with long- term (more than one year) exposure to Doxorubicin pegylated liposomal SUN or those receiving a cumulative Doxorubicin pegylated liposomal SUN dose greater than 720 mg/m2.
Cases of secondary oral cancer were diagnosed both, during treatment with Doxorubicin pegylated liposomal SUN, and up to 6 years after the last dose. Patients should be examined at regular intervals for the presence of oral ulceration or any oral discomfort that may be indicative of secondary oral cancer.

The dose should be repeated as long as patients respond satisfactorily and tolerate treatment. Day 4 dosing of both medicinal products may be delayed up to 48 hours as medically necessary. Doses of bortezomib should be at least 72 hours apart.
AIDS-related KS Doxorubicin pegylated liposomal SUN is administered intravenously at 20 mg/m2 every two- to-three weeks. Avoid intervals shorter than 10 days as medicinal product accumulation and increased toxicity cannot be ruled out.
Treatment of patients for two-to-three months is recommended to achieve a therapeutic response. Continue treatment as needed to maintain a therapeutic response. 8), immediately discontinue the infusion, give appropriate premedications (antihistamine and/or short acting corticosteroid) and restart at a slower rate.
