Outcome Measures

Primary Outcome Measures

  1. Number of Participants (Par.) With Any Recurrence of the Initial Disease, Second Primary Cancer, Contralateral Breast Cancer, or Death (Disease-free Survival [DFS]) [From randomization until date of the first occurrence of an objective disease recurrence, a second primary cancer, or death from any cause (assessed up to 6 years; 1 year of treatment, 5 years of follow-up [median of 5.3 years for final analysis])]

    DFS=interval between the date of randomization and the date of the first occurrence of an objective disease recurrence, a second primary cancer, or death from any cause. The date of the event is the earliest date of the occurrence of any of the following: local recurrence (LR) following mastectomy; LR in ipsilateral breast following lumpectomy; regional recurrence; distant recurrence; contralateral breast cancer, including ductal carcinoma in situ; other second primary cancer (excluding squamous or basal cell carcinoma of the skin, melanoma in situ, carcinoma in situ of the cervix, or lobular carcinoma in situ of the breast); death from any cause without a prior event. Par. who started additional anti-cancer adjuvant therapy prior to the recurrence of their disease were to be censored. Par. who did not withdraw from the study and did not experience a specified event or death were to be censored (follow-up ongoing) at the last visit date available at which progression was assessed.

Secondary Outcome Measures

  1. Number of Participants Who Died (Overall Survival) [From the date of randomization until death from any cause (assessed up to 6 years; 1 year of treatment and 5 years of follow-up [median of 5.3 years for final analysis])]

    Overall Survival (OS) is defined as the time from randomization until death from any cause. Data are presented as the number of participants who died. For participants who did not die, time to death was censored at the last date the participant was known to be alive.

  2. Percentage of Participants With the Indicated Period of Recurrence-free Survival (Time to First Recurrence) [From the date of randomization until the date of the first occurrence of an objective disease recurrence or contralateral breast cancer (assessed up to 6 years; 1 year of treatment and 5.3 years of follow-up [median of 5 years for final analysis])]

    Recurrence is defined as experiencing a recurrence of initial disease or contralateral breast cancer after randomization. Time to first recurrence is defined as the interval between the date of randomization and the date of the first occurrence of an objective disease recurrence or contralateral breast cancer. Time to first recurrence included the first occurrence at one of the following sites as an event: local recurrence following mastectomy; local recurrence in ipsilateral breast following lumpectomy; regional recurrence; distant recurrence; contralateral breast cancer, including ductal carcinoma in situ (DCIS).

  3. Percentage of Participants With the Indicated Period of Distant Recurrence-free Survival (Time to Distant Recurrence) [From the date of randomization until the date of the first occurrence of a distant recurrence (assessed up to 6 years; 1 year of treatment and 5 years of follow-up [median of 5.3 years for final analysis])]

    Distant recurrence (metastatic disease) is defined as a tumor in any area of the body not including those defined as local or regional recurrence. Sites of distant recurrence include: skin, subcutaneous tissue, and lymph nodes (excluding those described for local and regional recurrence); bone marrow; skeletal; lungs and pleural; ascites and pleural effusions; liver and other viscera; and central nervous system (CNS). Time to distant recurrence is defined as the interval between the date of randomization and the date of the first occurrence of a distant recurrence.

  4. Time to Central Nervous System (CNS) Recurrence [From the date of randomization until the date of the first occurrence of a CNS recurrence (assessed up to 6 years [1 year of treatment and 5 years of follow-up; median of 5.3 years for final analysis])]

    Time to CNS recurrence is defined as the interval between the date of randomization and the date of the occurrence of a CNS recurrence if noted as part of the participant's first recurrence. Time to CNS recurrence was not calculated; data are presented as the number of participants with CNS recurrence in the subsequent outcome measure table.

  5. Number of Participants With CNS Recurrence [From the date of randomization until the date of the first occurrence of a CNS recurrence (assessed up to 6 years [1 year of treatment and 5 years of follow-up; median of 5.3 years for final analysis])]

    The number of participants experiencing a CNS recurrence was summarized.

  6. Modified Disease-free Survival (MDFS) [From the date of randomization until the date of the first occurrence of an objective disease recurrence, contralateral breast cancer, or death from any cause (assessed up to 6 years)]

    Modified disease recurrence=interval between the date of randomization and the date of the first occurrence of an objective disease recurrence, contralateral breast cancer, or death from any cause. The date of the event=the earliest date of the occurrence of any of the following events: local recurrence following mastectomy; local recurrence in ipsilateral breast following lumpectomy; regional recurrence; distant recurrence; contralateral breast cancer, including DCIS; death from any cause without a prior event. MDFS was not calculated; data are presented as the number of participants with any recurrence of the initial disease, contralateral breast cancer, or death (disease-free survival) in the subsequent outcome measure table.

  7. Number of Participants With Any Recurrence of the Initial Disease, Contralateral Breast Cancer, or Death (Disease-free Survival [DFS]) [From the date of randomization until the date of the first occurrence of an objective disease recurrence, contralateral breast cancer, or death from any cause (assessed up to 6 years)]

    DFS=interval between the date of randomization and the date of the first occurrence of an objective disease recurrence, a second primary cancer, or death from any cause. The date of the event is the earliest date of the occurrence of any of the following: local recurrence (LR) following mastectomy; LR in ipsilateral breast following lumpectomy; regional recurrence; distant recurrence and contralateral breast cancer, including ductal carcinoma in situ; or death from any cause without a prior event. Participants who started additional anti-cancer adjuvant therapy prior to the recurrence of their disease were to be censored. Participants who did not withdraw from the study and did not experience a specified event or death were to be censored (follow-up ongoing) at the last visit date available at which progression was assessed.

  8. Change From Baseline in Short Form-36 Version 2 (SF-36 v2) Scores for the Physical Component Summary (PCS) [Baseline, Month 6, Month 12, and every 6 months after discontinuation of study treatment for 24 months (up to a maximum of 3 study years)]

    The SF-36 v2 is a self-administered, health-related quality of life (QoL) metric. It is a 36-item questionnaire designed to measure 8 domains of functional health status and well-being: physical functioning, role-physical, bodily pain, general health perceptions, vitality, social functioning, role-emotional, and mental health. Each domain is scored from 0 (poorer health) to 100 (better health).The PCS score is a summary score representing overall physical health, which is derived from the 8 domain scores. As with each domain score, the PCS score ranges from 0 to 100; higher scores represent better health. Change from Baseline was calculated as the post-Baseline score minus the Baseline score. Missing post-Baseline data were imputed using the last observation carried forward (LOCF) method. The scores were analyzed using an analysis of covariance (ANCOVA) model, adjusting for Baseline sub-scale score, treatment, and country. Positive changes from Baseline indicate improvement.

  9. Change From Baseline in SF-36 v2 Scores for the Mental Component Summary (MCS) [Baseline, Month 6, Month 12, and every 6 months after discontinuation of study treatment for 24 months (up to a maximum of 3 study years)]

  11. Number of Participants With Hematology Values Outside the Reference Range for the Indicated Parameters [At Baseline and every 3 months thereafter up to Month 12/Early Withdrawal Visit]

    The hematology parameters assessed were: basophils (Bs) in giga (10^9) per liter (GI/L) and in percentage (%), eosinophils (Eo) in GI/L and %, hematocrit, hemoglobin, lymphocytes (Lmph) in GI/L and %, monocytes (Mono) in GI/L and %, platelet count, Red Blood Cell (RBC) count, total neutrophil count (TNC) in GI/L and %, and White Blood Cell (WBC) count. The Baseline (BL) value is the last available pre-treatment result recorded. "Any post-Baseline value" was based on results recorded at any scheduled or unscheduled post-Baseline visits. The prevalence of values lying outside the reference (ref.) range (high or low) is presented for BL and "any post-Baseline" (APBL) visit. Two participants were randomized to placebo but received lapatinib; therefore, they are included in the lapatinib treatment arm. Data for the primary analysis (conducted in 2011) are reported.

  12. Number of Participants With Clinical Chemistry Values Outside the Reference Range for the Indicated Parameters [At Baseline and every 6 weeks thereafter up to Month 12/Early Withdrawal Visit]

    The clinical chemistry parameters assessed were: alanine amino transferase (ALT), albumin, alkaline phosphatase (ALP), aspartate amino transferase (AST), bicarbonate, blood urea nitrogen (BUN), bone alkaline phosphatase (Bone ALP), calcium, chloride, creatinine, creatinine clearance (Cr. Clearance), creatinine clearance estimated (Cr. Clrnc. est.), glucose, potassium, sodium, total bilirubin (Total Bln), total protein, urea, and uric acid. The Baseline (BL) value is the last available pre-treatment result recorded. "Any post-Baseline" value was based on results recorded at scheduled or unscheduled post-Baseline visits. The prevalence of values lying outside the reference (ref.) range (high or low) was presented for BL and "any post-Baseline" (APBL) visit. Two participants were randomized to placebo but received lapatinib; therefore, they are included in the lapatinib treatment arm.

  13. Number of Participants With Non-laboratory Toxicities of the Indicated Toxicity Grades [From the first dose of study treatment up to 12 months]

    Non-laboratory toxicities are defined as adverse events (AEs). The number of partcipants with any treatment-emergent AE of the indicated toxicity grade are summarized. Toxicity grading was according to the National Cancer Institute Common Terminology Criteria for Adverse Events Version 3.0 as follows: Grade 1=mild; Grade 2=moderate; Grade 3=severe; Grade 4=life threatening; Grade 5=death. The events that were not given a toxicity grade are categorized as "Not Applicable."

  14. Number of Participants Experiencing Primary or Secondary Cardiac Events [From the date of randomization up to 12 months]

    A cardiac event is classified as a primary cardiac endpoint (PCE) or a secondary cardiac endpoint (SCE). PCE is defined as: cardiac death (cardiac death due to heart failure, myocardial infarction, or arrhythmia;or probable cardiac death defined as sudden, unexpected death within 24 hours of a definite or probable cardiac event); severe symptomatic congestive heart failure (CHF) (as per New York Heart Association [NYHA] Class III or IV and an absolute decrease in left ventricular ejection fraction [LVEF] of more than 10 percentage points from Baseline and to a left ventricular ejection fraction [LVEF] value below 50%). SCE is defined as asymptomatic or mildly symptomatic cardiac events (NYHA Class I or II) and a significant decrease in LVEF, defined as an absolute decrease in LVEF of more than 10 percentage points from Baseline and to an LVEF value below 50%.

  15. Number of Participants With the Indicated Electrocardiogram (ECG) Findings [Screening and Month 12/Early Withdrawal Visit]

    12-lead ECG measurements were taken at Screening and at study conclusion/withdrawal. The number of participants with normal, abnormal clinically significant (CS), and abnormal not clinically significant (NCS) ECG findings, as classified by the investigator, were summarized. Participants with missing values were categorized as missing. Data for the primary analysis (conducted in 2011) are reported.

Title Change From Baseline in Short Form-36 Version 2 (SF-36 v2) Scores for the Physical Component Summary (PCS)
Description The SF-36 v2 is a self-administered, health-related quality of life (QoL) metric. It is a 36-item questionnaire designed to measure 8 domains of functional health status and well-being: physical functioning, role-physical, bodily pain, general health perceptions, vitality, social functioning, role-emotional, and mental health. Each domain is scored from 0 (poorer health) to 100 (better health).The PCS score is a summary score representing overall physical health, which is derived from the 8 domain scores. As with each domain score, the PCS score ranges from 0 to 100; higher scores represent better health. Change from Baseline was calculated as the post-Baseline score minus the Baseline score. Missing post-Baseline data were imputed using the last observation carried forward (LOCF) method. The scores were analyzed using an analysis of covariance (ANCOVA) model, adjusting for Baseline sub-scale score, treatment, and country. Positive changes from Baseline indicate improvement.

12. Secondary Outcome
Title Number of Participants With Hematology Values Outside the Reference Range for the Indicated Parameters
Description The hematology parameters assessed were: basophils (Bs) in giga (10^9) per liter (GI/L) and in percentage (%), eosinophils (Eo) in GI/L and %, hematocrit, hemoglobin, lymphocytes (Lmph) in GI/L and %, monocytes (Mono) in GI/L and %, platelet count, Red Blood Cell (RBC) count, total neutrophil count (TNC) in GI/L and %, and White Blood Cell (WBC) count. The Baseline (BL) value is the last available pre-treatment result recorded. "Any post-Baseline value" was based on results recorded at any scheduled or unscheduled post-Baseline visits. The prevalence of values lying outside the reference (ref.) range (high or low) is presented for BL and "any post-Baseline" (APBL) visit. Two participants were randomized to placebo but received lapatinib; therefore, they are included in the lapatinib treatment arm. Data for the primary analysis (conducted in 2011) are reported.
Time Frame At Baseline and every 3 months thereafter up to Month 12/Early Withdrawal Visit

Outcome Measure Data

Analysis Population Description
Safety Population (SP): all randomized participants (par.) who received >=1 dose of randomized treatment. Only those par. available (n=X, X in the category titles) at the specified time points were analyzed. Different par. may have been analyzed for different parameters, so the overall number of par. analyzed reflects everyone in the SP.
Arm/Group Title Lapatinib 1500 mg Placebo
Arm/Group Description Participants received lapatinib 1500 milligrams (mg) orally once daily. Treatment was continued for a maximum of 12 months or until disease recurrence or development of a second primary cancer, withdrawal from study treatment due to unacceptable toxicity, or consent withdrawal. Participants received matching placebo orally once daily. Treatment was continued for a maximum of 12 months or until disease recurrence or development of a second primary cancer, withdrawal from study treatment due to unacceptable toxicity, or consent withdrawal.

Title Number of Participants With Clinical Chemistry Values Outside the Reference Range for the Indicated Parameters
Description The clinical chemistry parameters assessed were: alanine amino transferase (ALT), albumin, alkaline phosphatase (ALP), aspartate amino transferase (AST), bicarbonate, blood urea nitrogen (BUN), bone alkaline phosphatase (Bone ALP), calcium, chloride, creatinine, creatinine clearance (Cr. Clearance), creatinine clearance estimated (Cr. Clrnc. est.), glucose, potassium, sodium, total bilirubin (Total Bln), total protein, urea, and uric acid. The Baseline (BL) value is the last available pre-treatment result recorded. "Any post-Baseline" value was based on results recorded at scheduled or unscheduled post-Baseline visits. The prevalence of values lying outside the reference (ref.) range (high or low) was presented for BL and "any post-Baseline" (APBL) visit. Two participants were randomized to placebo but received lapatinib; therefore, they are included in the lapatinib treatment arm.
Time Frame At Baseline and every 6 weeks thereafter up to Month 12/Early Withdrawal Visit

Safety Population (primary analysis [conducted in 2011]). Only those participants available (represented as n=X, X in the category titles) at the specified time points were analyzed. Different participants may have been analyzed for different parameters, so the overall number of participants analyzed reflects everyone in the Safety Population.
Arm/Group Title Lapatinib 1500 mg Placebo
Arm/Group Description Participants received lapatinib 1500 milligrams (mg) orally once daily. Treatment was continued for a maximum of 12 months or until disease recurrence or development of a second primary cancer, withdrawal from study treatment due to unacceptable toxicity, or consent withdrawal. Participants received matching placebo orally once daily. Treatment was continued for a maximum of 12 months or until disease recurrence or development of a second primary cancer, withdrawal from study treatment due to unacceptable toxicity, or consent withdrawal.

Title Number of Participants With Non-laboratory Toxicities of the Indicated Toxicity Grades
Description Non-laboratory toxicities are defined as adverse events (AEs). The number of partcipants with any treatment-emergent AE of the indicated toxicity grade are summarized. Toxicity grading was according to the National Cancer Institute Common Terminology Criteria for Adverse Events Version 3.0 as follows: Grade 1=mild; Grade 2=moderate; Grade 3=severe; Grade 4=life threatening; Grade 5=death. The events that were not given a toxicity grade are categorized as "Not Applicable."
Time Frame From the first dose of study treatment up to 12 months

Title Number of Participants Experiencing Primary or Secondary Cardiac Events
Description A cardiac event is classified as a primary cardiac endpoint (PCE) or a secondary cardiac endpoint (SCE). PCE is defined as: cardiac death (cardiac death due to heart failure, myocardial infarction, or arrhythmia;or probable cardiac death defined as sudden, unexpected death within 24 hours of a definite or probable cardiac event); severe symptomatic congestive heart failure (CHF) (as per New York Heart Association [NYHA] Class III or IV and an absolute decrease in left ventricular ejection fraction [LVEF] of more than 10 percentage points from Baseline and to a left ventricular ejection fraction [LVEF] value below 50%). SCE is defined as asymptomatic or mildly symptomatic cardiac events (NYHA Class I or II) and a significant decrease in LVEF, defined as an absolute decrease in LVEF of more than 10 percentage points from Baseline and to an LVEF value below 50%.
