Time to Progression as Evaluated by the Investigator

Assessment method [1]

0
Time to progression (TTP) is defined as the interval between the date of randomization and the earliest date of progression of disease (PD) or death due to breast cancer. The investigator assessed PD based on radiological PD (imaging data) and clinical symptomatic progress (Response Evaluation Criteria in Solid Tumors \[RECIST\] Criteria: target lesion (TL), at least a 20% increase in the sum of largest diameter (LD) of TLs or the appearance of one or more new lesions; non-TL (NTL), the appearance of one or more new lesions and/or unequivocal progression of existing NTLs). TTP was assessed in participants who died due to breast cancer or progressed, as assessed by the investigator, as well as in those who were censored and completed follow-up and those who were censored but are still being followed. For censored participants (those without a documented date of disease progression/death due to breast cancer), the date of the last radiographic assessment was used.

The percentage of participants with tumor response is defined as those participants with measurable disease who achieved either a complete response (CR) or partial response (PR). The Response Evaluation Criteria in Solid Tumors (RECIST) was used to evaluate the measurability of tumor lesions, to determine target lesion (TLs) and non-target lesion (NTLs). CR (TLs and NTLs): the disappearance of all TLs and NTLs; PR (for TLs): at least a 30% decrease in the sum of the largest diameter (LD) of TLs, taking as a reference the Baseline sum LD; PR (for NTLs): persistence of one or more lesions.

PFS is defined as the interval between the date of randomization and the earliest date of disease progression or death due to any cause, if sooner. Six months PFS is defined as PFS at six months from the time of randomization. Raw data for 6 months PFS are not available; thus, data are presented as the number of participants who progressed or died at or prior to 6 months. For TLs, progressive disease is defined asat least a 20% increase in the sum of the LD of TLs or the appearance of 1 or more new lesions. For NTLs, progressive disease is defined as the appearance of 1 or more new lesions and/or unequivocal progression of existing NTLs. PFS was assessed in participants who died or progressed, as well as in those who were censored and completed follow-up and those who were censored but are still being followed. For censored participants (those without a documented date of disease progression/death due to breast cancer), the date of the last radiographic assessment was used.

The FACT-B questionnaire was designed to measure multidimensional quality of life (QOL) in participants with breast cancer. The physical and functional well-being subscale scores range from 0 to 28, based on 7 questions (each scored from 0 \[not at all\] to 4 \[very much\] for all subscales); the emotional and social/family well-being (1 question optional) subscale scores range from 0 to 24 (based on 6 questions), and the additional concerns subscale score ranges from 0 to 40, based on 10 questions. The FACT-B Total Score (0 \[better QOL\] to 144 \[worse QOL\]) is the sum of the subscale scores.

The Press Laboratory collected tumor tissues of participants for ErbB2 testing. ErbB2 testing is done to detect breast cancer and predict its likely outcome. All samples were analyzed by the Press Laboratory. Participants were categorized as ErbB2 positive (overexpression of the ErbB2 gene), ErbB2 negative, and assay not done (which included participants with no available samples and those with inconclusive results). ErbB2 status is determined by immunohistochemistry (ICH) assay and fluorescence in situ hybridization (FISH) testing. Negative ErbB2 status is defined as 0 or 1+ by IHC, or as 2+ by IHC and FISH.

The Press Laboratory collected tumor tissues of participants for biomarker testing. All samples were analyzed by the Press Laboratory. The ratio of ErbB2 gene signals to chromosome 17 signals, which indicates the progression of breast cancer, was calculated. Low levels of amplification (few copies) may have a ratio of 2-5, whereas high levels of amplification may have a ratio \>10.

Assessment method [14]

The Press Laboratory tested tumor tissue samples (taken at Screening, prior to randomization to study treatment) to determine intra-tumoral expression levels of ErbB1, ErbB2, and other analytes associated with these pathways by IHC, the process of detecting antigens (e.g., proteins) in cells of a tissue section. The IHC assessment is expressed as: 0, no staining (no cancer cells); 1+, faint staining; 2+, weak to moderate complete staining; 3+, strong complete staining (many cancer cells). A status of "Assay not done" was assigned to participants with no available samples and to those with inconclusive results. If strong staining is observed, breast cancer that has high levels of HER2 expression (overexpression) is indicated. If moderate/weak staining is observed (IHC=2+), breast cancer that has low/moderate expression levels is indicated. When no staining is observed (IHC=0), breast cancer HER2 expression may be below the level of detection of the assay.

The Press Laboratory tested participants who were 2+ (weak to moderate complete staining) or 3+ (strong complete staining) for ErbB2 overexpression by IHC for ErbB2 gene amplification using the FISH assay. The results of the FISH assay can be ErbB2 gene "amplification" (increased number of copies of the ErbB2 gene) or "non-amplification" (not many copies of the ErbB2 gene). A status of "Assay not done" was assigned to those participants with no available samples and to those with inconclusive results (e.g., due to hybridization or staining problems).
