• Adult patients, aged at least 18 years
• Histologically confirmed invasive breast cancer with clinical staging T1-4, N0-3, M0 (no metastasis)
• HER2-positive tumor as confirmed by central laboratory HER2 testing (immunohistochemistry and/or in-situ hybridization)
• Completion of preoperative systemic chemotherapy and HER 2 directed treatment. Systemic therapy must consist of at least 6 cycles of chemotherpay with a total duration at least 16 weeks, including at least 9 weeks of trastuzumab and at least 9 weeks of taxane based chemotherapy. Patients may have received an anthracycline as part of preoperative therapy in addition to taxane chemotherapy.
• Surgical removal of all clinically-evident disease in the breast and lymph nodes
• Pathologic evidence of residual invasive carcinoma in the breast or axillary lymph nodes following completion of preoperative therapy. If invasive disease is present in both breasts, residual invasive carcinoma must be present in at least 1 breast or axillary lymph nodes postoperatively.
• ECOG performance status of 0 or 1
• Life expectancy of at least 6 months from the first dose of study treatment
• Adequate organ function as determined by the following laboratory results, within 14 days prior to randomization
• Women of childbearing potential and men with partners of childbearing potential must be willing to use effective contraception as defined by protocol for the duration of study treatment and for at least 7 months after the last dose of study treatment.

• Treatment with any investigational anticancer drug within 28 days prior to commencing 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, or other malignancies with an expected curative outcome
• Peripheral neuropathy greater or equal to Grade 2
• Uncontrolled cardiopulmonary dysfunction (e.g., high blood pressure, angina, serious cardiac arrhythmia)
• Active liver disease like hepatitis
• Other current, severe, uncontrolled systemic disease (e.g., clinically significant metabolic disease, wound healing disorders, ulcers)
• For female patients, current pregnancy or lactation
• Major surgical procedure or significant traumatic injury within 28 days prior to randomization or anticipation of the need for major surgery during the course of study treatment
• Currrent, serious, uncontrolled Infections or known infection with HIV.

- Primary Outcome Measures
Name Time Method Main Objective: To compare the length of time it takes for the primary breast cancer to recur after treatment with preoperative chemotherapy followed by surgery between the 2 treatment arms.;<br> Secondary Objective: To compare the length of time it takes for:<br> • the primary breast cancer to develop in other location(s)<br> • occurrence of secondary cancers in other organs<br> • death<br> To compare side effects of the study medication between the 2 treatment arms.<br> ;Primary end point(s): Invasive disease-free survival (IDFS);Timepoint(s) of evaluation of this end point: up to 10 years
- Secondary Outcome Measures
Name Time Method <br> Secondary end point(s): 1. IDFS including second non-breast cancer<br> 2. Disease-free survival (DFS), including second non-breast cancer or contralateral or ipsilateral ductal carcinoma in situ<br> 3. Overall survival (OS)<br> 4. Recurrence-free interval (RFI): time between randomization and local, regional or distant breast cancer recurrence <br> 5. Distant recurrence-free interval (DRFI): time between randomization and distant breast cancer recurrence<br> 6. Cardiac and overall safety: Incidence of adverse events <br> 7. Quality of life: EORTC QLQ-C30, QLQ-BR23 and EQ-5D questionnaires.<br> ;<br> Timepoint(s) of evaluation of this end point: 1 to 6. up to 13 years<br> 7. up to 3 years<br>
