Not accepted
You may be eligible if
Prospective centrally-assessed HER2-positive disease (i.e., immunohistochemistry \[IHC\] 3 + and/or gene amplified \[HER2 to CEP 17 ratio ≥ 2\] by in situ hybridization \[ISH\]) through use of archival paraffin-embedded tumor tissue. Both IHC and ISH assays will be performed; however, only one positive result from either method is required for eligibility
Tumor tissue block or eight unstained freshly cut slides must be available for central laboratory HER2 testing. Archival tumor samples obtained from primary and/or metastatic sites are acceptable
For participants with bilateral BC, HER2-positive status must be demonstrated in both locations or in a metastatic site
Histologically or cytologically confirmed invasive breast cancer (BC): incurable, unresectable, LABC previously treated with multimodality therapy or metastatic breast cancer (MBC)
Prior treatment for BC in the adjuvant, unresectable, locally advanced, or metastatic setting must include taxane, alone or in combination with another agent, and trastuzumab, alone or in combination with another agent in the adjuvant, unresectable, locally advanced, or metastatic setting
Documented progression of incurable, unresectable LABC or MBC: Progression must occur during or after most recent treatment for LABC or MBC or within 6 months after completing adjuvant therapy
Baseline disease that must be evaluable per Response Evaluation Criteria for Solid Tumors Version 1.1 (RECIST v1.1). Participants with CNS-only disease are excluded
Eastern Cooperative Oncology Group Performance Status (ECOG PS) 0 or 1
Left ventricular ejection fraction (LVEF) ≥50% by either echocardiogram (ECHO) or multiple-gated acquisition (MUGA)
You may not be if
Prior treatment with trastuzumab emtansine, lapatinib, or capecitabine
Last dose of prior chemotherapy or trastuzumab within 21 days before the first dose of study treatment
Hormonal therapy within 7 days before the first dose of study treatment
Treatment with any other anti-cancer therapy/investigational drug (not defined above) within 21 days prior to randomization, except hormone therapy, which can be given up to 7 days prior to randomization; recovery of treatment-related toxicity consistent with other eligibility criteria before the first dose of treatment
Radiation therapy within 2 weeks before the first dose of study treatment, and with any related acute toxicity (Grade ≥1)
Brain metastases that are untreated, symptomatic, progressive, or require therapy, such as radiation or surgery, within 28 days before the first dose of study treatment
History of other malignancy within the previous 5 years, except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, Stage I uterine cancer, synchronous or previously diagnosed HER2-positive BC, or cancers with a similar curative outcome as those mentioned above
Peripheral neuropathy Grade ≥3 per National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI CTCAE) v4.03
History of exposure to the following cumulative doses of anthracyclines as specified below:
* Doxorubicin \> 500 mg/m\^2
* Epirubucin \> 720 mg/m\^2
* Mitoxantrone \> 120 mg/m\^2 If another anthracycline or more than one anthracycline has been used, then the cumulative dose must not exceed the equivalent of 500 mg/m\^2 doxorubicin.
* Unstable angina or serious cardiac arrhythmia not controlled by medication
* Baseline LVEF \<50% by either ECHO or MUGA scan
* History of symptomatic congestive heart failure (Grade ≥3 per NCI CTCAE v4.03 or Class ≥II per New York Heart Association criteria)
* History of LVEF \<40% or symptomatic CHF during prior trastuzumab treatment
* Myocardial infarction within 6 months before the first dose of study treatment
* Current dyspnea at rest because of complications of advanced malignancy or any medical need for continuous oxygen therapy
