Clinical Trial Summary

The aim of this study is to demonstrate the bioequivalence of DOXIL/CAELYX, 40 mg/m2 (IV infusion over 90 minutes) between two manufacturing facilities. According to the Food and Drug Administration (FDA), two products are considered to be bioequivalent when they are equal in the rate and extent to which the active pharmaceutical ingredient (API) becomes available at the site(s) of drug action. Any abnormalities of the safety endpoints (Clinical Laboratory Test, Electrocardiogram, Left Ventricular Ejection Fraction, Physical Examination) will be captured as Adverse Events.

Eligibility

Inclusion Criteria:

1. Be a man or woman aged from 18 to 75 years, inclusive.

2. Patients with advanced or refractory ovarian or breast cancer, expected to require at least 2 cycles of DOXIL/CAELYX therapy at Screening, are eligible for treatment per

this study protocol. This includes:

1. Histologically or cytologically confirmed advanced ovarian cancer failing platinum-based chemotherapy

2. Histologically or cytologically confirmed metastatic breast cancer after failing approved life-prolonging therapies

5. Recovered from the acute toxicity of any prior treatment (exemptions: alopecia, neuropathy Grade I). All toxicities from prior treatment should return to baseline or Grade I.

6. Prior doxorubicin (or other anthracyclines) at cumulative dose of = 240 mg/m2 or cumulative epirubicin dose = 720 mg/m2 (calculated using doxorubicin equivalent doses: 1 mg doxorubicin = 1 mg DOXIL/CAELYX = 0.3 mg mitoxantrone = 0.25 mg idarubicin). Patients without any prior anthracycline exposure can also be included.

7. Adequate liver function as determined by serum total bilirubin levels = 1.2 mg/dL, and serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels = 2.5 x ULN.

8. Adequate bone marrow function, as determined by an absolute neutrophil count (ANC) = 1500/mm3 (or = 1.5 x 109/L), a platelet count = 100,000/mm3 (or = 100 x 109/L), and a hemoglobin level = 9 g/dL (or = 90 g/L), in the absence of transfusion requirements or cytokine support for at least 7 days prior to enrolling in the study.

9. Adequate renal function (mL/min), as determined by multiplying estimated glomerular filtration rate (e-GFR) by the body surface area (BSA) and dividing the value by 1.73 m2.

10. Left ventricular ejection fraction (LVEF) within normal limits of the institution, as determined by multiple uptake gated acquisition (MUGA) or echocardiography.

11. Female patients (of childbearing potential) must use medically acceptable methods of birth control (e.g., prescription oral contraceptives, contraceptive injections, contraceptive patches, intrauterine devices, the double-barrier method, male partner sterilization) before enrollment, throughout the study and for at least 8 months after the last DOXIL/CAELYX infusion.

12. Male patients must agree to use an adequate contraception method as deemed appropriate by the Investigator and always use condoms when sexually active during the study. Medically acceptable methods of contraception that may be used by the patient and/or his partner include oral contraceptives, contraceptive injections, contraceptive patches, intrauterine devices, the double-barrier method, and surgical sterilization (vasectomy or tubal ligation) for minimally 6 months after the last administration of DOXIL/CAELYX. Sperm donation is not allowed during the study and for minimally 6 months after the last administration of DOXIL/CAELYX.

13. Negative pregnancy test (urinary or serum beta-human chorionic gonadotropin [ß-HCG]) at Screening (applicable to women of childbearing potential) within 7 days prior to starting treatment.

14. Patients with no history of addiction to any recreational drug or drug dependence or alcohol addiction.

15. Patients must have signed an informed consent form indicating that they understand the purpose and procedures required, and are willing to participate in the study.

Exclusion Criteria:

11. A patient with uncontrolled concurrent illness including, but not limited to, poorly controlled hypertension or diabetes, or psychiatric illness/social situation that may potentially impair the patient's compliance with study procedures.

12. Concomitant use of strong CYP3A4 inhibitors (such as clarithromycin, diltiazem, erythromycin, itraconazole, ketoconazole, nefazodone, ritonavir, telithromycin and verapamil) and strong CYP3A4 inducers (such as carbamazepine, phenobarbital, phenytoin, rifampin and St John's wort) from at least 4 weeks before the first dose of DOXIL/CAELYX in Cycle 1 and until after completion of all PK sampling on Day 26 of Cycle 2.

13. Has any condition that, in the opinion of the Investigator, would make participation not be in the best interest (e.g., compromise the well-being) of the patient or that could prevent, limit, or confound the protocol-specified assessments.

14. Is a woman who is pregnant, or breast-feeding, or planning to become pregnant within 8 months or is a man who plans to father a child while enrolled in this study or within 6 months after the last dose of study drug.
