Inclusion Criteria

1. Signed written informed consent approved by the relevant Institutional Ethical Review Board (IRB).
2. Female or male patients aged 18 years or older.
3. Histologically or cytologically confirmed and documented adenocarcinoma of the breast with metastatic or locally advanced disease not amenable to curative resection.
4. HER2-positive (defined as either immunohistochemistry
[IHC] 3+ or in situ hybridization [ISH] positive) as assessed by local laboratory on primary or metastatic tumor (ISH positivity is defined as a ratio of 2.0 or greater for the number of HER2 gene copies to the number of signals for CEP17, or for single probe tests, a HER2 gene count greater than 4).
5. At least one measurable lesion and/or non-measurable
disease evaluable according to Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1 (Eisenhauer et al. 2009).
6. Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.
7. Left ventricular ejection fraction (LVEF) of at least 55%.
8. Negative pregnancy test in women of childbearing potential (premenopausal or less than 12 months of amenorrhea post-menopause, and who have not undergone surgical sterilization).
9. For women of childbearing potential who are sexually active, agreement to use a highly effective, nonhormonal form of contraception or two effective forms of non-hormonal contraception during and for at least 6 months post-study treatment.
10. Fertile males willing and able to use effective nonhormonal
means of contraception (barrier method of contraception in conjunction with spermicidal jelly, or surgical sterilization) during and for at least 6 months post-study treatment.
11. Life expectancy of at least 12 weeks.

Exclusion Criteria

1. Previous systemic non-hormonal anticancer therapy in the
metastatic or locally advanced breast cancer setting. Note: Prior to study entry, up to two lines of hormonal therapy for metastatic or locally recurrent disease are permitted, one of which may be in combination with everolimus.
2. Previous approved or investigative anti-HER2 agents in any breast cancer treatment setting, except trastuzumab and/or
lapatinib in the adjuvant or neoadjuvant setting.
3. Disease progression while receiving trastuzumab and/or
lapatinib in the adjuvant or neoadjuvant setting.
4. Disease-free interval from completion of adjuvant or neo-adjuvant systemic non-hormonal treatment to recurrent disease of less than 6 months.
5. History of persistent Grade 2 or higher (NCI-CTC, Version
4.0) hematological toxicity resulting from previous adjuvant
or neoadjuvant therapy.
6. Patient with radiographic evidence of central nervous system (CNS) metastases as assessed by computed tomography (CT) or
magnetic resonance imaging (MRI) that are not well controlled (symptomatic or requiring control with continuous corticosteroid therapy [eg dexamethasone]) Note: Patients with CNS metastases are permitted to participate in the study if the CNS metastases are medically well controlled prior to screening (as assessed by the investigator) after receiving local therapy (irradiation, surgery etc) but without anti-HER2 therapy.
7. Current peripheral neuropathy of Grade 3 or greater
(NCI-CTC, Version 4.0).
8. History of other malignancy (other than bilateral or previously diagnosed HER2-positive mBC) within the last 5 years, except
for carcinoma in situ of the cervix, non-melanoma skin carcinoma, Stage 1 uterine cancer, or cancers with a similar curative outcome as those mentioned above.
9. Serious uncontrolled concomitant disease that would
contraindicate the use of any of the investigational drugs
used in this study or that would put the patient at high risk for
treatment-related complications.
10. Inadequate organ function, evidenced by the following laboratory results:
• Absolute neutrophil count <1,500 cells/mm3
• Platelet count <100,000 cells/mm3
• Hemoglobin <9 g/dL
• Total bilirubin greater than upper limit of normal (ULN) (unless the patient has documented Gilbert’s syndrome)
• Aspartate aminotransferase AST; SGOT) or alanine aminotransferase (ALT; SGPT) >2.5 × ULN (>5 x ULN in patients with liver metastases)
• Alkaline phosphatase levels > 2.5 x ULN (>5 x ULN in patients with liver metastased, or > 10 x ULN in patients with bone metastases)
• AST (SGOT) or ALT (SGPT) >1.5 × ULN with concurrent serum alkaline phosphatase >2.5 × ULN
• Serum creatinine >2.0 mg/dL or 177 µmol/L
• International normalized ratio (INR) and activated partial thromboplastin time (aPTT) or partial thromboplastin time (PTT) >1.5 × ULN (unless on therapeutic coagulation)
11. Uncontrolled hypertension (systolic >150 mm Hg and/or diastolic >100 mm Hg) or clinically significant (i.e. active) cardiovascular disease: including but not limited to cerebrovascular accident (CVA)/stroke or myocardial infarction within 6 months prior to first study treatment, unstable angina, congestive heart failure (CHF) of New York Heart Association (NYHA) Grade II or higher, serious cardiac arrhythmia requiring medication or other cardiovasclar problem that is uncontrolled or is currently controlled with medication.
