Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Invasive Disease-Free Survival (IDFS) Event (Excluding Second Primary Non-Breast Cancer [SPNBC]), as Assessed Using Radiologic, Histologic Examinations or Laboratory Findings
Time Frame: Randomization to the first occurrence of IDFS event (excluding SPNBC) (until data cut-off date 19 December 2016; median [range] follow-up: 3.8 [0-4.9] years)
Percentage of participants with IDFS events (excluding SPNBC) is reported. IDFS event was defined as the first occurrence of one of the following events: Ipsilateral invasive breast tumor recurrence (that is [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 ductal carcinoma in situ [DCIS] and lobular carcinoma in situ [LCIS]) and non-melanoma skin cancer were excluded as an event.
Randomization to the first occurrence of IDFS event (excluding SPNBC) (until data cut-off date 19 December 2016; median [range] follow-up: 3.8 [0-4.9] years)
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
Time Frame: 3 years
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.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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
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
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.
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
Change From Baseline in EORTC QLQ-C30 Functioning Subscale Scores
Time Frame: Baseline, Weeks 13, 25; EOT (28 days after the last dose, up to Week 56); FU Months 18, 24, 36
EORTC QLQ-C30 is a cancer-specific instrument with 30 questions used to assess the overall QOL in cancer participants.

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.

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

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.
