11.Patient who has known sensitivity to any of the products to be administered during the study, including mammalian cell derived drug products, trastuzumab, and murine proteins, or to any of the excipients.
12.Patient who has previously participated in this study.
13.Patient who will likely not be available to complete all protocol required study visits or procedures.
14.Patient who has history or evidence of any other clinically significant disorder, condition, or disease (with the exception of those outlined above) that, in the opinion of the investigator, would pose a risk to patient safety or interfere with the study evaluation, procedures, or completion.
15.Patient who has pre-existing, clinically significant (>Grade 1 by CTCAE v.4.03) peripheral neuropathy |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint will be the pCR, defined as the absence of invasive tumor cells in the breast and in axillary lymph nodes, regardless of DCIS. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The pCR will be determined at the time of surgery, using hematoxylin and eosin evaluation of the resected breast specimen. |
|
E.5.2 | Secondary end point(s) |
The secondary efficacy endpoints will be the following:
•Overall response rate, defined as complete response or partial response as assessed by RECIST Version 1.1
•DFS, measured from the time of occurrence of attained CR to disease recurrence or death as a result of any cause
•PFS, measured from the randomization to disease recurrence, progression or death from any cause
•OS, defined as time from randomization to death from any cause
•Breast conservation rate, measured as the proportion of patients who undergo breast conservation surgery
•Other pCRs
•pCRB
•pCR of breast and axillary nodes with absence of DCIS
The secondary PK endpoints during the Neoadjuvant Period will be the following:
•Observed maximum serum concentration after administration (Cmax), at each dose
•Observed trough serum concentration (Ctrough), prior to next dose for Cycle 1 to Cycle 7, and at EOT1 for dose 8.
The secondary pharmacodynamic endpoint is serum HER2 shed antigen during the Neoadjuvant Period
The secondary safety endpoints will be the following:
•Incidence and severity of AEs, including SAEs graded according to the NCI CTCAE Version 4.03.
•Cardiotoxicity, as assessed by mean change from Baseline to endpoint assessment in LVEF.
•Immunogenicity, as assessed by the incidence of antidrug antibody.
Biomarker Endpoints (Optional):
The FcγR genotype (FcγRIIa, IIIa, and/or any necessary genotypes) will be evaluated as secondary endpoints.
