Primary Outcome Measures

Measure:	Overview of the Number of Participants With at Least One Treatment-Emergent Adverse Event, Severity Determined According to National Cancer Institute Common Terminology Criteria for Adverse Events, Version 4.0 (NCI-CTCAE v4.0)
Time Frame:	From Baseline until 28 days after, or 7 months after (only for serious AEs related to study drug), the last dose of study treatment. The median (full range) duration of exposure to any study treatment was 16.2 (0.0-86.4) months.
Safety Issue:
Description:	Treatment-emergent adverse events (TEAEs) were adverse events (AEs) that started or worsened in severity on or after the first administration of study drug, up to and including 28 days after the last dose. The investigator graded all AEs for severity per NCI-CTCAE v4.0; if not listed, the AE was assessed as follows: Grade 1 = mild; Grade 2 = moderate; Grade 3 = severe; Grade 4 = life-threatening/disabling; Grade 5 = death. The investigator determined whether an AE was related to study drug and independently assessed severity and seriousness of each AE. TEAEs to monitor included anaphylaxis and hypersensitivity, cardiac dysfunction, diarrhoea Grade ≥3, pregnancy-related AEs, interstitial lung disease, infusion-/administration-related reactions, mucositis, (febrile) neutropenia, rash/skin reactions, and suspected transmission of infectious agent. TEAEs of special interest included LVEF decreased, liver enzymes increased, and suspected transmission of infectious agent by the study drug.

Secondary Outcome Measures

Measure:	Progression-Free Survival, as Assessed by the Investigator Using Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1)
Time Frame:	From date of enrollment until date of disease progression or death, whichever occurred first. The median (full range) duration of follow-up was 68.73 (0.03-87.29) months.
Safety Issue:
Description:	Progression-free survival (PFS) was defined as the time between the date of enrollment and the date of first radiographically documented progressive disease assessment (by the investigator using RECIST v1.1) or death, whichever occurred first. PFS was analyzed using a Kaplan-Meier approach. Participants who had neither progressed nor died at the time of clinical cut-off or who were lost to follow-up were censored at the date of the last evaluable tumor assessment (response assessment with the latest end date); if no post-baseline assessments were available, such participants were censored at Day 1. If a participant missed 2 or more consecutive visits, then they were censored at the last evaluable visit prior to the missed visits. Tumor assessments were performed every 3 cycles (1 cycle is 3 weeks) for up to 36 months and at least every 12 cycles thereafter during treatment, and at least every 36 weeks post-treatment (if progression-free after 36 months), until disease progression.

Responses according to RECIST v1.1 are defined as follows: CR = Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 millimetres (mm).; PR = At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

Measure:	Time to Response for Participants With Best Overall Response of Complete Response or Partial Response, as Assessed by the Investigator Using RECIST v1.1
Time Frame:	From date of first study treatment until date of first confirmed response (CR or PR). The median (full range) duration of follow-up was 68.73 (0.03-87.29) months.
Safety Issue:
Description:	Time to response (TTR) was defined as the time from the first study treatment administration to the date of first confirmed response (CR or PR). TTR was analyzed using a Kaplan-Meier approach. Participants who did not have CR or PR were censored at the date of their last evaluable tumor assessment. Participants for whom no post-baseline tumor assessments were available were censored at Day 1. Responses according to RECIST v1.1 are defined as follows: CR = Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 millimetres (mm).; PR = At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

Measure:	Change From Baseline in Functional Assessment of Cancer Therapy - Breast Cancer (FACT-B) Questionnaire Total Score Over the Course of the Study
Time Frame:	Baseline, every 3 cycles (1 cycle is 3 weeks) during treatment period, and 28 days post-treatment safety follow-up. The median (full range) duration of exposure to any study treatment was 16.2 (0.0-86.4) months.
Safety Issue:
Description:	The FACT-B questionnaire (version 4) was administered only to female participants to assess quality of life in five subscales: physical, social, emotional, and functional well-being, and breast cancer. Participants were given a series of statements in each subscale and were asked to rate how true each statement was for them during the past 7 days on a 5-point scale ranging from 0 (not at all) to 4 (very much). The calculated FACT-B total score, ranging from 0 to 148, was the sum of the scores for each subscale, provided that at least 80% of the items had been answered; a higher score indicated a better quality of life. If any of the 5 subscale scores were missing, the total score was also set to missing. Baseline was defined as the last non-missing measurement taken prior to first dose of study treatment (including unscheduled assessments). Post-baseline values were summarized for planned visits only.

Measure:	Change From Baseline in FACT-B Questionnaire Physical Well-Being Subscale Score Over the Course of the Study
Time Frame:	Baseline, every 3 cycles (1 cycle is 3 weeks) during treatment period, and 28 days post-treatment safety follow-up. The median (full range) duration of exposure to any study treatment was 16.2 (0.0-86.4) months.
Safety Issue:
Description:	The FACT-B questionnaire (version 4) was administered only to female participants to assess quality of life in five subscales: physical, social, emotional, and functional well-being, and breast cancer. For the physical well-being subscale, participants were given a series of 7 statements and were asked to rate how true each statement was for them during the past 7 days on a 5-point scale ranging from 0 (not at all) to 4 (very much). The calculated FACT-B physical well-being subscale score, ranging from 0 to 28, was the sum of the scores for each statement only if at least 50% of items had been answered; the higher the score, the better the quality of life. Baseline was defined as the last non-missing measurement taken prior to first dose of study treatment (including unscheduled assessments). Post-baseline values were summarized for planned visits only.

Measure:	Change From Baseline in FACT-B Questionnaire Social Well-Being Subscale Score Over the Course of the Study
Time Frame:	Baseline, every 3 cycles (1 cycle is 3 weeks) during treatment period, and 28 days post-treatment safety follow-up. The median (full range) duration of exposure to any study treatment was 16.2 (0.0-86.4) months.
