•Overexpression by immunohistochemistry categorized as IHC2+ with FISH, CISH, or DISH confirmation.
Determination of HER2 positive status using one of the Sponsor approved analytical test methods listed in the Case Record Form
If HER2 status is unavailable or was determined using a test other than a Sponsor-approved assay listed in Appendix 1 of the Protocol, eligibility must be documented prior to randomization: a. Confirmed by the
Sponsor-provided central laboratory;b. HER2 local testing using both an IHC and an in-situ hybridization analytical test neither of which are considered Sponsor approved. The results from both assays must be unequivocal (ie, IHC result must be categorized as IHC3+).
7. Measurable disease in the breast after diagnostic biopsy, defined as longest diameter ≥ 2.0 cm.
8. Known Estrogen Receptor (ER) and Progesterone Receptor (PR) hormone status at study entry.
9. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
10. Left ventricular ejection fraction (LVEF) of ≥ 55% by 2D echocardiogram (ECHO) or Multi Gated Acquisition Scan (MUGA).
11. Normal bone marrow function as defined by:

•hemoglobin > 10.0 g/dL.
12. Normal hepatic function as defined by:
•total bilirubin ≤ 1.5 x upper limit of normal (ULN) (<3 ULN if Gilberts disease);
•aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) ≤ 2.5 x upper limit of normal (ULN) (≤ 5x ULN if liver metastases are present).
13. Patients with an elevated unconjugated bilirubin (Gilbert's syndrome) will be eligible if hepatic enzymes and function are otherwise within normal limits (ie, AST, ALT, and Alkaline Phosphatase are within normal limits), and there is no evidence of hemolysis.
14. Serum creatinine ≤ 1.5 × ULN or estimated creatinine clearance (CrCl) ≥ 50 mL/min calculated by the Cockcroft-Gault.
15. Patients of childbearing potential must agree to use a highly effective methods of contraception as described in Section 4.4 Life Style Guidelines of the Protocol, throughout the study and for 12 months after
the last dose of assigned treatment. A patient is of childbearing potential if, in the opinion of the investigator, she is biologically capable of having children and is sexually active.
16. Patients who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.

2. Bilateral breast cancer.
3. Inflammatory breast cancer.

9. Severe dyspnea at rest requiring supplementary oxygen therapy.
10. Known or demonstrated viral infection as listed below. Testing to demonstrate eligibility is required only in countries where regulations mandate testing. In all other countries, testing should be considered if a patient is at risk for having undiagnosed infection (for
example due to history of injection drug use or due to geographic location).
a.Seropositivity for human immunodeficiency virus (HIV);
b. Hepatitis B and/or hepatitis C infection (as detected by positive testing for hepatitis B surface antigen [HbsAg] or antibody to hepatitis C virus [anti HCV] with confirmatory testing).
11. Recent infection requiring a course of systemic anti-infectives that were completed ≤ 14 days before enrollment (with the exception of uncomplicated urinary tract infection).
12. Participation in other studies involving investigational drug(s) (Phases 1-4) within ≥ 4 weeks before randomization and/or during study participation. Patients participating in observational studies not involving an investigational drug(s) and/or long-term follow up of studies involving an investigational drug(s) in which treatment was completed 4 weeks before randomization are not excluded.
13. History of severe hypersensitivity reaction to platinum-coordination compounds, taxanes, trastuzumab, murine proteins, or excipients in their formulations.
14. Clinical contraindication to treatment with steroids preventing use as part of Taxotere® premedication.
15. Pregnant females; breastfeeding females; females of childbearing potential who are unwilling or unable to use two highly effective methods of contraception as outlined in this protocol for the duration of the study and for 12 months after last dose of investigational product.

17. Other severe acute or chronic medical or psychiatric condition including recent (within the past year) or active suicidal ideation or behavior, or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study.
18. Unwilling or unable to comply with the lifestyle guidelines described in this protocol.
