Kaplan-Meier Estimate of the Percentage of Participants Who Were IDFS Event-Free (Excluding SPNBC) at 3 Years, as Assessed Using Radiologic, Histologic Examinations or Laboratory Findings

Kaplan-Meier estimate of the percentage of participants who were IDFS event-free (excluding SPNBC) at 3 years is reported. IDFS event was defined as the first occurrence of one of the following events: Ipsilateral invasive breast tumor recurrence (i.e., an invasive breast cancer involving the same breast parenchyma as the original primary lesion); ipsilateral local-regional invasive breast cancer recurrence (i.e., an invasive breast cancer in the axilla, regional lymph nodes, chest wall, and/or skin of the ipsilateral breast); distant recurrence (i.e., evidence of breast cancer in any anatomic site - other than the two above mentioned sites); death attributable to any cause; contralateral invasive breast cancer. All SPNBCs and in situ carcinomas (including DCIS and LCIS) and non-melanoma skin cancer were excluded as an event.

Time frame: 3 years

Population: ITT population. The overall number of participants analyzed is the number of participants remaining at risk for IDFS event (excluding SPNBC) at 3 years.

Change From Baseline in EORTC QLQ-BR23 Symptom Scale Score

EORTC-QLQ-BR23 is a 23-item breast cancer-specific companion module to the EORTC-QLQ-C30 and consists of four functional scales (body image, sexual enjoyment, sexual functioning, future perspective \[FP\]) and four symptom scales (systemic side effects \[SE\], upset by hair loss, arm symptoms, breast symptoms). Questions used 4-point scale (1=not at all, 2=a little, 3=quite a bit, 4=very much). Scores averaged and transformed to 0-100 scale. High score for symptom scale indicated high level of symptomatology/problems/greater degree of symptoms. Negative change from Baseline indicated deterioration in QOL and positive change from Baseline indicated an improvement in QOL.

Time frame: Baseline, Weeks 13, 25; EOT (28 days after the last dose, up to Week 56); FU Months 18, 24, 36

Population: ITT population. Overall number of participants analyzed=participants evaluable for this outcome measure. Number analyzed=participants evaluable for this outcome measure at specified timepoint.

Change From Baseline in EORTC QLQ-C30 Disease/Treatment-Related Symptoms Subscale Scores

EORTC QLQ-C30 is a cancer-specific instrument with 30 questions used to assess the overall QOL in cancer participants. First 28 questions used 4-point scale (1=not at all, 2=a little, 3=quite a bit, 4=very much) for evaluating 5 functional scales (physical, role, social, cognitive, emotional), 8 symptom scales/items (diarrhea, fatigue, dyspnea, appetite loss, insomnia, nausea and vomiting \[N/V\], constipation, and pain) and a single item (financial difficulties). Last 2 questions represented participant's assessment of overall health and quality of life, coded on 7-point scale (1=very poor to 7=excellent). EORTC QLQ-C30 disease/treatment-related symptom scores were linearly transformed on a scale of 0 to 100, with a high score indicating a higher level of symptoms. Negative change from Baseline values indicated improvement in symptoms and positive values indicated worsening of symptoms.

Time frame: Baseline, Weeks 13, 25; EOT (28 days after the last dose, up to Week 56); FU Months 18, 24, 36

Population: ITT population. Overall number of participants analyzed=participants evaluable for this outcome measure. Number analyzed=number of participants responding to this scale where it is considered complete as defined by the EORTC QLQ-C30 scoring manual.

Change From Baseline in EORTC QLQ-C30 Financial Difficulties Subscale Scores

EORTC QLQ-C30 is a cancer-specific instrument with 30 questions used to assess the overall QOL in cancer participants. First 28 questions used 4-point scale (1=not at all, 2=a little, 3=quite a bit, 4=very much) for evaluating 5 functional scales (physical, role, social, cognitive, emotional), 8 symptom scales/items (diarrhea, fatigue, dyspnea, appetite loss, insomnia, N/V, constipation, and pain) and a single item (financial difficulties). Last 2 questions represented participant's assessment of overall health and quality of life, coded on 7-point scale (1=very poor to 7=excellent). EORTC QLQ-C30 financial difficulties scores were linearly transformed on a scale of 0 and 100, with a high score indicating a higher level of financial difficulties. Negative change from Baseline values indicated improvement in financial difficulties and positive values indicated worsening of financial difficulties.

Time frame: Baseline, Weeks 13, 25; EOT (28 days after the last dose, up to Week 56); FU Months 18, 24, 36

Population: ITT population. Overall number of participants analyzed=participants evaluable for this outcome measure. Number analyzed=number of participants responding to this scale where it is considered complete as defined by the EORTC QLQ-C30 scoring manual.

EORTC QLQ-C30 is a cancer-specific instrument with 30 questions used to assess the overall QOL in cancer participants. First 28 questions used 4-point scale (1=not at all, 2=a little, 3=quite a bit, 4=very much) for evaluating 5 functional scales (physical, role, social, cognitive, emotional), 8 symptom scales/items (diarrhea, fatigue, dyspnea, appetite loss, insomnia, N/V, constipation, and pain) and a single item (financial difficulties). Last 2 questions represented participant's assessment of overall health and quality of life, coded on 7-point scale (1=very poor to 7=excellent). EORTC QLQ-C30 functioning scores were linearly transformed on a scale of 0 to 100, with a high score indicating better functioning/support. Negative change from Baseline values indicated deterioration in functioning and positive values indicated improvement.

Change From Baseline in European Organisation for Research and Treatment of Cancer - Breast Cancer Module Quality of Life (EORTC QLQ-BR23) Functional Scale Score

EORTC-QLQ-BR23 is a 23-item breast cancer-specific companion module to the EORTC-QLQ-C30 and consists of four functional scales (body image, sexual enjoyment, sexual functioning, future perspective \[FP\]) and four symptom scales (systemic side effects \[SE\], upset by hair loss, arm symptoms, breast symptoms). Questions used 4-point scale (1=not at all, 2=a little, 3=quite a bit, 4=very much). Scores averaged and transformed to 0-100 scale. High score for functional scale indicated high/better level of functioning/healthy functioning. Negative change from Baseline indicated deterioration in QOL and positive change from Baseline indicated an improvement in QOL.

Time frame: Baseline, Weeks 13, 25; EOT (28 days after the last dose, up to Week 56); FU Months 18, 24, 36

Population: ITT population. Overall number of participants analyzed=participants evaluable for this outcome measure. Number analyzed=participants evaluable for this outcome measure at specified timepoint.

Change From Baseline in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Core 30 (EORTC QLQ-C30) Global Health Status (GHS) Scale Score

EORTC QLQ-C30 is a cancer-specific instrument with 30 questions used to assess the overall quality of life (QOL) in cancer participants. First 28 questions used 4-point scale (1=not at all, 2=a little, 3=quite a bit, 4=very much) for evaluating 5 functional scales (physical, role, social, cognitive, emotional), 8 symptom scales/items (diarrhea, fatigue, dyspnea, appetite loss, insomnia, nausea and vomiting \[N/V\], constipation, and pain) and a single item (financial difficulties). Last 2 questions represented participant's assessment of overall health and quality of life, used 7-point scale (1=very poor to 7=excellent). EORTC QLQ-C30 global scores were linearly transformed on a scale of 0 to 100, with a high score indicating better GHS/QOL. Negative change from Baseline values indicated deterioration in QOL or functioning and positive values indicated improvement.

Time frame: Baseline, Weeks 13, 25; end of treatment (EOT, 28 days after the last dose, up to Week 56); Follow-up (FU) Months 18, 24, 36

Population: ITT population. Overall number of participants analyzed=participants evaluable for this outcome measure. Number analyzed=number of participants responding to this scale where it is considered complete as defined by the EORTC QLQ-C30 scoring manual.

Percentage of Participants With Response for European Quality of Life-5 Dimensions-3 Level (EQ-5D-3L) Questionnaire: Mobility Domain

EQ-5D-3L is a descriptive system of health-related quality of life states consisting of 5 dimensions/domains (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) and each of which has 3 levels of severity (no problems \[scored as 1\], some or moderate problems \[scored as 2\], and extreme problems \[scored as 3\]). Percentage of participants with each of the following responses in mobility domain was reported: I have no problems in walking about; I have some problems in walking about; and I am confined to bed. Response percentages may not add up to 100% due to data rounding.

Time frame: Baseline, Weeks 13, 25; EOT (28 days after the last dose, up to Week 56); FU Months 18, 24, 36

Population: ITT population. Number analyzed=participants evaluable for this outcome measure at specified timepoint.
