Change From Baseline (CFB) in European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) Patient-reported Function (Role Functioning [Q6, Q7]) Baseline (Cycle 1 Day 1), Day 1 of Cycles 4, 6, 8, 10, 12, 14 & 16; end of treatment/discontinuation (approximately at Day 351); Follow up: Months 3 to 48 (Total duration is up to 5 years); Cycles 1-5= 28 day cycles; Cycles 6-16: 21 day cycles The EORTC QLQ-C30 is a cancer specific health-related quality-of life (QoL) questionnaire. For the role functioning scale, participant responses to the 2 questions "Q6: Were you limited in doing either your work or daily activities" and "Q7: Were you limited in pursuing your hobbies or other leisure time activities" were scored on a 4-point scale (1=Not at All to 4=Very Much). The scores were linearly transformed on a scale of 0 to 100, with a low score indicating better functioning. Negative change from baseline indicated improvement.
Invasive Disease-Free Survival (iDFS) in the Node Positive Subpopulation From randomization until the occurrence of an iDFS event or death from any cause, whichever occurred earlier (up to 5 years) iDFS = the time from randomization until the date of the first occurrence of one of the following events: Ipsilateral invasive breast tumor recurrence (an invasive breast cancer involving the same breast parenchyma as the original primary lesion); Ipsilateral local-regional invasive breast cancer recurrence (an invasive breast cancer in the axilla, regional lymph nodes, chest wall, and/or skin of the ipsilateral breast); Ipsilateral second primary invasive breast cancer; Contralateral invasive breast cancer; Distant recurrence (evidence of breast cancer in any anatomic site \[other than the sites mentioned\]) that has either been histologically confirmed and/or clinically/radiographically diagnosed as recurrent invasive breast cancer; and Death attributable to any cause, including breast cancer, non-breast cancer, or unknown cause. Analysis used Kaplan-Meier estimates where participants with no events at the time of analysis or no post-baseline information were censored.
Overall Survival (OS) From randomization up to death from any cause (up to 5 years) Overall Survival (OS) is defined as the time from randomization to the date of death due to any cause. Analysis used Kaplan-Meier estimates where participants with no events at the time of analysis or no post-baseline information were censored.
Invasive Disease-Free Survival (iDFS) Including Second Primary Non-Breast Invasive Cancer From randomization up to death from any cause (up to 5 years) iDFS = the time from randomization until the date of first occurrence of one of the events: Ipsilateral invasive breast tumor recurrence (an invasive breast cancer involving same breast parenchyma as the original primary lesion); Ipsilateral local-regional invasive breast cancer recurrence (an invasive breast cancer in axilla, regional lymph nodes, chest wall, \&/or skin of the ipsilateral breast); Ipsilateral second primary invasive breast cancer; Second primary non-breast invasive cancer; Contralateral invasive breast cancer; Distant recurrence (i.e., evidence of breast cancer in any anatomic site \[other than sites mentioned\]) that has either been histologically confirmed \&/or clinically/radiographically diagnosed as recurrent invasive breast cancer; Death attributable to any cause, including breast cancer, non-breast cancer, or unknown cause. Analysis used Kaplan-Meier estimates where participants with no events at the time of analysis or no post-baseline information were censored.
Distant Recurrence-Free Interval (DRFI) From randomization up to 5 years Distant Recurrence-Free Interval (DRFI) was defined as the time from randomization to the distant breast cancer recurrence. Analysis used Kaplan-Meier estimates where participants with no events at the time of analysis, participants with no events who died, or participants with no post-baseline information were censored.
Change From Baseline in EORTC QLQ-C30 Global Health Status (GHS) [Q29] and Health-Related Quality of Life (HRQoL) [Q30] Combined Score Baseline (Cycle 1 Day 1), Day 1 of Cycles 4, 6, 8, 10, 12, 14 & 16; end of treatment/discontinuation (approximately 351 days); Follow up: Months 3 to 48 (Total duration is up to 5 years); Cycles 1-5= 28 day cycles; Cycles 6-16: 21 day cycles The EORTC QLQ-C30 is a cancer specific health-related quality-of life (QoL) questionnaire. Participant responses to the questions regarding Global Health Status (Q29:GHS; "How would you rate your overall health during the past week?") and Quality of Life (Q30: QoL; "How would you rate your overall quality of life during the past week?") are scored on a 7-point scale (1= Very poor to 7=Excellent). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher score indicates a better outcome. Negative change from Baseline values indicated deterioration in QOL or functioning and positive values indicated improvement.
Number of Participants With Adverse Events (AE) Up to 5 years An Adverse Event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product, regardless of causal attribution. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. AEs are reported based on the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), Version 5.0.
Change From Baseline in EORTC QLQ-C30 Patient-reported Function (Physical Functioning [Q1-Q5]) Baseline (Cycle 1 Day 1), Day 1 of Cycles 4, 6, 8, 10, 12, 14 & 16; end of treatment/discontinuation (approximately at Day 351); Follow up: Months 3 to 48 (Total duration is up to 5 years); Cycles 1-5= 28 day cycles; Cycles 6-16: 21 day cycles The EORTC QLQ-C30 is a cancer specific health-related quality-of life (QoL) questionnaire. For the physical functioning scale, participant responses to 5 questions about daily activities (strenuous activities, long walks, short walks, bed/chair rest \& needing help with eating, dressing, washing themselves, or using the toilet) were scored on a 4-point scale (1=Not at All to 4=Very Much). The scores were linearly transformed on a scale of 0 to 100, with a high score indicating worst functioning. Negative change from baseline indicated improvement in functioning.
