Ability to comply with the study protocol, in the investigator's judgment
Eastern Cooperative Oncology Group (ECOG) Performance Status ≤1
Female and male patients with Stage II - IIIC (T2-T4 plus any N, or any T plus N1-N3, M0), locally advanced, inflammatory, or early-stage, unilateral, and histologically confirmed invasive breast cancer
Primary tumor \>2 cm in diameter, or node-positive disease (clinically or on imaging, and node positivity confirmed with cytology and/or histopathology)
HER2-positive breast cancer confirmed by a central laboratory prior to study enrollment. HER2-positive status will be determined based on pretreatment breast biopsy material.
Hormone receptor status of the primary tumor, centrally confirmed
Patient agreement to undergo mastectomy or breast conserving surgery after neoadjuvant therapy
Availability of formalin-fixed, paraffin-embedded (FFPE) tumor tissue block for central confirmation of HER2 and hormone receptor status and additional biomarker research
Baseline left ventricular ejection fraction (LVEF) ≥55% measured by echocardiogram (ECHO) or multiple-gated acquisition scan (MUGA)
For women of childbearing potential (WOCBP) who are sexually active: agreement to remain abstinent or use one highly effective non-hormonal contraceptive method with a failure rate of \<1% per year, or two effective non-hormonal contraceptive methods during the treatment period and for 7 months after the last dose of HER2-targeted therapy, and agreement to refrain from donating eggs during this same period
For men: men must remain abstinent or use a condom with a spermicidal product during the treatment period and for 7 months after the last dose of HER2-targeted therapy to avoid exposing the embryo. Men must refrain from donating sperm during this same period.
A negative serum pregnancy test must be available prior to randomization for WOCBP, unless they have undergone surgical sterilization
No major surgical procedure unrelated to breast cancer within 28 days prior to randomization or anticipation of the need for major surgery during the course of study treatment
You may not be if
Stage IV (metastatic) breast cancer
Patients with a history of invasive breast cancer
Patients with a history of concurrent or previously treated non-breast malignancies except for appropriately treated 1) non-melanoma skin cancer and/or 2) in situ carcinomas, including cervix, colon, and skin
Patients who have received any previous systemic therapy for treatment or prevention of breast cancer, or radiation therapy for treatment of cancer
Patients who have a past history of ductal carcinoma in situ or lobular carcinoma in situ if they have received any systemic therapy for its treatment or radiation therapy to the ipsilateral breast
Patients with high-risk for breast cancer who have received chemo-preventative drugs in the past are not allowed to enter the study
Patients with multicentric breast cancer, unless all tumors are HER2-positive
Patients with bilateral breast cancer
Patients who have undergone an excisional biopsy of primary tumor and/or axillary lymph nodes
Axillary lymph node dissection prior to initiation of neoadjuvant therapy
Sentinel lymph node biopsy prior to neoadjuvant therapy
Treatment with any investigational drug within 28 days prior to randomization
Serious cardiac illness or medical conditions
Inadequate bone marrow function, renal function or impaired liver function
Current severe, uncontrolled systemic disease that may interfere with planned treatment
Pregnant or breastfeeding, or intending to become pregnant during the study or within 7 months after the last dose of HER2-targeted therapy
Any serious medical condition or abnormality in clinical laboratory tests that, in the investigator's judgment, precludes the patient's safe participation in and completion of the study
Known active liver disease, for example, active viral hepatitis infection, autoimmune hepatic disorders, or sclerosing cholangitis
Concurrent, serious, uncontrolled infections, or known infection with HIV
Known hypersensitivity to study drugs, excipients, and/or murine proteins
Current chronic daily treatment with corticosteroids
History of other malignancy within 5 years prior to screening, except for appropriately treated carcinoma in situ of the cervix, colon, skin, and/or non-melanoma skin carcinoma
History of ventricular dysrhythmias or risk factors for ventricular dysrhythmias, such as structural heart disease, coronary heart disease, clinically significant electrolyte abnormalities, or family history of sudden unexplained death or long QT syndrome
