- EORTC QLQ-C30: cancer-specific instrument with 30 questions to assess the participant QoL. First 28 questions used to evaluate 5 functional scales (physical, role, cognitive, emotional, social), 3 symptom scales (fatigue, nausea and vomiting, pain) and other single items (dyspnea, appetite loss, insomnia, constipation, diarrhea, financial difficulties). Each question assessed on 4-point scale (1= not at all, 2= a little, 3= quite a bit, 4= very much); functional scales: higher score = better level of functioning; symptom scale: higher score = more severe symptoms; for single items: higher score= more severe problem. Last 2 questions used to evaluate global health status (GHS)/QoL. Each question was assessed on 7-point scale (1= very poor to 7= excellent). Scores averaged, transformed to 0-100 scale; higher score=better quality of life/better level of functioning. Change from baseline was calculated by subtracting the baseline value from the average value of Week 4 to 160.

- TTD was defined as the time (in months) from randomization to the first observation with a\>=10 point increase and no subsequent observations with a \<10 point increase from baseline in breast symptom score based on the EORTC-QLQ-BR23. EORTC-QLQ-BR23 is a disease-specific module for breast cancer developed as a supplement for the EORTC-QLQ-C30 to assess the quality of life of participants with breast cancer. EORTC-QLQ-BR23 symptoms subscale includes 4 items: systemic therapy side effects, breast symptoms, arm symptoms, upset by hair loss. Each item is rated by choosing 1 of 4 possible responses that record the level of intensity (1= not at all, 2= a little, 3= quite a bit, and 4= very much), higher scores=high level of symptom/problems.

SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug or the day before initiation of a new antineoplastic therapy or 30 days after the date of the last dose date of study drug, whichever occurred first, that were absent before treatment or that worsened relative to pretreatment state.

NCI CTCAE v4.03 defined the severity grade as: grade 1 (mild), grade 2 (moderate), grade 3 (severe), grade 4 (potentially life threatening) and grade 5 (death related to AE) for each parameter. Key hematology parameters included hemoglobin (gram per liter \[g/L\]), leukocytes (10\^6 cells per liter), lymphocytes (10\^6 cells per liter), neutrophils (10\^6 cells per liter), and platelets (10\^9 cells per liter). Low value indicated lower values than the baseline values and high value indicated higher values than the baseline values.
