Brief Summary:
This is an open-label, multinational, randomized, multicenter trial designed to compare pegylated liposomal doxorubicin with capecitabine as first line chemotherapy of metastatic breast cancer. The primary objective of the study is to compare the time to disease progression, although overall response rates, overall survival, quality of life, time to treatment failure, and safety and tolerability will also be assessed.

Arm Intervention/treatment
Experimental: Pegylated liposomal doxorubicin Drug: Pegylated liposomal doxorubicin (SCH 200746)
pegylated liposomal doxorubicin (50 mg/m^2 q 28 days) was administered intravenously until disease progression or unacceptable toxicity
Active Comparator: Capecitabine Drug: Capecitabine
capecitabine (1250 mg/m^2 BID x 14 days q 21 days) in tablets of 150 mg and 500 mg was administered orally, until disease progression or unacceptable toxicity

Primary Outcome Measures :
  1. Time to Disease Progression (TTP) Using Response Evaluation Criteria in Solid Tumors (RECIST) [ Time Frame: From Day 1 (Cycle 1) until First Evidence/Diagnosis of Progressive Disease or Death ]
    TTP was defined as the time from onset of treatment with study drug until first evidence/diagnosis of progressive disease or - in the absence of any diagnosis of progressive disease - until the participant´s death. Diagnosis of progressive disease was done according to RECIST (Version 1.0) and/or investigator assessment based on RECIST. RECIST criteria used changes in the largest diameter of target/non-target lesions. Target (measurable) lesions were up to a maximum of 5 per organ & >20 mm by clinical imaging (>=10 mm with spiral CT scan). Non-target lesions were all other lesions.

Secondary Outcome Measures :
  1. Number of Participants With an Overall Response (Complete Response [CR] + Partial Response [PR]) Between PLD and Capecitabine Treatment Groups [ Time Frame: From Day 1 (Cycle 1) until First Evidence/Diagnosis of Progressive Disease or Death ]
    Overall responses by investigator assessment/RECIST criteria of participant responses; CR=disappearance of target/nontarget lesions + PR=30% decrease in longest diameter sum (noting baseline sum) of target lesions. RECIST used changes in the largest diameter of target/non-target lesions. Target lesions were up to a maximum of 5 per organ & >20 mm by clinical imaging (>=10 mm with spiral CT scan). Non-target lesions were all other lesions. Evaluation of progress was repeated every 3 months (+/-7 days) post first date of lesion measurements, in detection absence until the participant´s death.

  2. Overall Survival Time in the PLD and Capecitabine Treatment Groups [ Time Frame: From Day 1 (Cycle 1) until Death ]
    Survival time was defined as duration time from onset of treatment with the study drug until death.

  3. Time to Treatment Failure in the PLD and the Capecitabine Treatment Groups [ Time Frame: From Day 1 (Cycle 1) until End of Treatment ]
    Time to treatment failure was defined as the duration of time from the date of the first administration of the study drug to the date of discontinuation of the study drug for any reason.

  4. Quality of Life (QoL) Measured by QoL Questionnaire (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) + Subjective Significance Questionnaire (SSQ)) [ Time Frame: From Screening to Day 1 of every Treatment Cycle up to 12 Cycles ]
    QoL questionnaire was an EORTC QLQ-C30 & SSQ integration. Scores on the SSQ scale ranged from 1 (very much worse) - 7 (very much better). SSQ consisted of 4 items which corresponded to core domains in the 30 Item EORTC QLQ-C30, such as improvement/deterioration in physical functioning, emotional functioning, social functioning, global QoL. Percentages were based on number of participants at each cycle & rounded to the nearest whole number. Early Withdrawal Questionnaires were obtained in 7-14 days of study drug final dose.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients must be female.
  • Patients must have metastatic disease of a cytological or histological confirmed breast cancer.
  • Patients must be 18 years or older.
  • Patients should have evaluable disease (at least uni-dimensionally measurable lesion according to the RECIST criteria in at least one site that has not been irradiated), however, patients who only have non-measurable/evaluable disease are not excluded. Also patients with only bone metastasis are not excluded.
  • Patients must have an Eastern Cooperative Oncology Group (ECOG) 0-2.
  • Patients must have a sufficient life expectancy to be treated with chemotherapy.
  • Patients must be willing and able to complete study questionnaires.
  • Patients must have adequate renal function as evidenced by serum creatinine <=1.5 mg/dL, or a creatinine clearance of >=45 mL/min (if serum creatinine is > 1.5 mg/dL but <= 1.8 mg/dL).
  • Patients must have adequate bone marrow function as evidenced by leukocyte count greater than 3.5 g/L, hemoglobin >=9.0 g/dL, and platelet count >=100x10^9/L.
  • Patients must have adequate liver function as evidenced by bilirubin of <=1.5 times the upper limits of normal (ULN) and alkaline phosphatase <=3 times, ULN unless related to liver metastasis.
  • Patients must have Sodium and Potassium values within normal limits.
  • Patients whose clinical condition (co-morbidity) allows a treatment with monotherapy or who expressed their wish to be treated with monotherapy.
  • Patients must have signed an informed consent document indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study.

Exclusion Criteria:

  • History of receiving prior chemotherapy in the metastatic setting (Note: patients may have had

hormonal therapy or chemotherapy in the adjuvant setting; patients may have received hormonal therapy in metastatic setting, patients may have received local radiotherapy).

  • Existing pregnancy or lactation (note on pregnancy test). A negative pregnancy test for women of childbearing potential has to be in place prior randomization (Note: A pregnancy test has to be done for patients who are not postmenopausal.
