Eligibility Criteria
Inclusion
- 1\. Primary breast cancer that is:
- Histologically confirmed invasive breast carcinoma with a primary tumor size of \> 2 cm by standard local assessment technique;
- Breast cancer staging ( in accordance with the American Joint Commitee on Cancer(AJCC) staging system (8th edition)): early-stage (T2-3, N0-1, M0) or locally advanced (T2-3, N2 or N3, M0; T4, any N, M0);
- HER2 positive confirmed by central laboratory, defined as immunohistochemistry (IHC) 3 +, or IHC 2+ and In Situ Hybridization (ISH) positive;
- Hormone receptor (HR, including estrogen receptor \[ER\] and progestin receptor \[PR\]) negative by central laboratory; ER negative is defined as \< 1% nuclear staining, and PR negative is defined as \< 1% nuclear staining.
- 2\. Left ventricular ejection fraction (LVEF) at baseline (within 42 days prior to randomization) ≥ 55% measured by echocardiography (ECHO) or multiple gated acquisition (MUGA) scan.
- 3\. Adequate major organ function, meeting the following criteria: Hematology (neither blood transfusion nor correction with hematopoietic stimulating factors within 14 days prior to randomization): white blood cell count ≥ 3.0 × 109/L; absolute neutrophil count ≥ 1.5 × 109/L; hemoglobin ≥ 90 g/L; platelet count ≥ 100 × 109/L; Serum chemistry: Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 × upper limit of normal (ULN), total bilirubin ≤ 1.5 × ULN; for subjects with known Gilbert syndrome, total bilirubin ≤ 2 × ULN; alkaline phosphatase ≤ 2.5 × ULN, serum creatinine ≤ 1.5 × ULN.
- 4\. Women of child-bearing potential have a negative result of serum pregnancy test at screening (within 7 days prior to randomization) and not in lactation, or are infertile. Male participants and women of childbearing potential use a "highly effective" contraceptive measures until 7 months after the last dose of investigational/reference product.
Exclusion
- Inflammatory breast cancer.
- Stage IV (metastatic) breast cancer, bilateral breast cancer, or multicentric (multiple tumors involving more than 1 quadrant) breast cancer.
- History of other malignancy within 5 years prior to screening (except for who have received radical treatment of carcinoma in situ of the cervix, basal cell carcinoma or squamous cell carcinoma of the skin ).
- With serious heart disease or medical history, including but not limited to the following conditions:
- 1\) History of documented heart failure or systolic dysfunction with any NYHA classification(LVEF \< 50%); 2) High-risk uncontrolled arrhythmia, such as atrial tachycardia with a heart rate\> 100 bpm at rest, significant ventricular arrhythmia (e.g.,ventricular tachycardia), or higher-grade atrioventricular (AV) block (i.e.,Mobitz II second-degree AV block or third degree AV block); 3) Unstable angina pectoris, or angina pectoris requiring anti-angina medication; 4) Evidence of transmural myocardial infarction on ECG; 5) Clinically-significant valvular heart disease; 6) Poorly controlled hypertension (systolic blood pressure\> 150 mmHg and/or diastolic blood pressure\> 100 mmHg).
