简要总结
The aim of this study is to evaluate the efficacy and safety of TQB2102 compared to TCbHP in the neoadjuvant treatment of HER2-positive breast cancer. Participants will randomly assigned, in a 1:1 ratio, to receive either TQB2102 or TCbHP for 6 cycles. Patients will undergo definitive surgery (breast conservation or mastectomy with sentinel lymph-node evaluation or axillary dissection) 3 to 6 weeks after the last cycle of the neoadjuvant phase. Primary endpoint is pathological complete response, defined as pathological stage ypT0/Tis ypN0 at the time of definitive surgery.

入选标准
- •18-70 years,
- •ECOG performance status 0-1;
- •Clinical T2-T4, or T1c with axillary lymph node metastasis; Confirmed HER2-positive status (per 2018 ASCO/CAP HER2 Testing Guidelines, defined as IHC 3+ or FISH positive);
- •Clinically measurable lesion: Lesion measurable by ultrasound, mammography, or optional MRI within 1 month before randomization;
- •No chemotherapy contraindications based on organ and bone marrow function tests within 1 month prior to chemotherapy: Absolute neutrophil count (ANC) ≥1.5×10⁹/L, Hemoglobin ≥90 g/L, Platelet count ≥100×10⁹/L, Total bilirubin <1.5 × ULN (upper limit of normal), Creatinine <1.5 × ULN, AST/ALT <1.5 × ULN, Echocardiography: Left ventricular ejection fraction (LVEF) ≥50%;
- •For women of childbearing potential: Negative serum pregnancy test within 14 days before randomization;
- •Signed informed consent form.
排除标准
- •Stage IV (metastatic) breast cancer;
- •Prior treatments received including chemotherapy, endocrine therapy, targeted therapy, or radiotherapy; History of other malignancies within 3 years or concurrent malignancies. Exceptions: Other malignancies treated with surgery alone achieving ≥5-year disease-free survival (DFS) . Cured cervical carcinoma in situ or non-melanoma skin cancer;
- •Major non-breast cancer-related surgical procedures within 4 weeks prior to enrollment, or incomplete recovery from such procedures;
- •Significant cardiac disease or conditions including but not limited to: History of heart failure or systolic dysfunction (LVEF <50%). Uncontrolled high-risk arrhythmias: Atrial tachycardia, resting heart rate >100 bpm, significant ventricular arrhythmias (e.g., ventricular tachycardia), or high-grade atrioventricular block (Mobitz II second-degree or third-degree AV block). Angina requiring anti-anginal medication. Clinically significant valvular heart disease. ECG evidence of transmural myocardial infarction. Poorly controlled hypertension (SBP >180 mmHg and/or DBP >100 mmHg);
- •Contraindications to chemotherapy per investigator's assessment due to severe uncontrolled comorbidities;
- •Known hypersensitivity to protocol drug components;
- •History of immunodeficiency disorders (including HIV positivity), other acquired/congenital immune deficiencies, or organ transplantation;
- •Any concurrent condition that in the investigator's judgment would jeopardize patient safety or compromise study completion, or other grounds for ineligibility.
