PFS is defined as the time from randomization until the earliest date of disease progression (PD) or death due to any cause, if sooner. The date of documented PD is defined as the date of radiological PD as assessed by the investigator based on imaging data and also by the clinical assessment of symptomatic progression. Per Response Evaluation Criteria in Solid Tumors (RECIST 1.0), PD is defined as a 20% increase in the sum of the longest diameter (LD) of target lesions, taking as a reference the smallest sum LD recorded since the treatment started, or the appearance of 1 or more new lesions.

OR is defined as the percentage of participants achieving either a confirmed complete response (CR) or partial response (PR). Response was assessed via Response Evaluation criteria in Solid Tumors (RECIST). The percentage of participants with response was calculated by using the formula: 100 \* (number of participants with CR + number of participants with PR)/total number of participants. CR: disappearance of all target lesions. PR: at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as a reference the baseline sum LD.

Quality of Life (QOL) was assessed using the FACT-B questionnaire, which was a 37-item (27 general and 10 breast cancer-specific questions) self-reporting instrument consisting of 5 dimensions: physical-, social/family-, emotional-, functional-well being, and a breast cancer subscale. Higher scores on the FACT-B scales (each ranging from 0 \[not at all\] to 4 \[very much\]) indicate a higher QOL. The score is transformed for FACT-B and results in a total score ranging from 0 to 144. Complete: completing at least 1 question from FACT-B.

FACT-G is a subscale of the FACT-B QOL questionnaire and consists of 27 questions grouped into 4 domains that measure a participant's physical, functional, social and family, and emotional well-being. FACT-G is assessed on a five-point Likert-type scale, with scores ranging from 0 to 4 (0=not at all, 1=a little bit, 2=somewhat, 3=quite a bit, 4=very much). The total score is calculated as the sum of the item scores on the subscale; the total ranges from 0 to 108, with higher score indicating a better quality of life.

IHC is a commonly used test to assess the amount of the HER2 receptor protein on the surface of the cancer cells. The IHC test results in a score of 0 to 3+, which indicates the amount of HER2 receptor protein on the cells in a sample of breast cancer tissue. Tissue scores of 0 to 1+ indicate HER2 negativity; scores of 2+ and 3+ indicate HER2 positivity. Clinical benefit is defined as participants with CR, PR, or SD for =\>6-month period.

The HER2 ECD is a glycoprotein that can be shed from the cell surface into the blood of normal individuals and can be elevated in different pathologic conditions. The serum HER2 ECD level generally reflects the tissue HER2 status. The HER2 ECD is quantified in serum with an enzyme-linked immunosorbent assay (ELISA). Non-Evaluable (NE): any participant who could not be classified as CR, PR, SD, or PD.

EGFR is a cell surface receptor tyrosine kinase expressed in certain types of tumors. Depending upon the staining intensity, EGFR was graded as follows: 0=absence of membrane staining above background in all tumor cells; EGFR-positive=staining is defined as any IHC staining of tumor cell membranes above background level, whether it is complete or incomplete circumferential staining (1+, 2+, 3+).
