Inclusion criteria
Inclusion criteria: 1.Subjects must voluntarily participate in this study, sign the informed consent form, demonstrate good compliance, and cooperate with follow-up visits. 2.Age >= 18 years. 3.ECOG score = 2cm) or T3-4 cN0-2). 5.Pathologically confirmed hormone receptor-negative (ER and PR negative) and HER2-negative advanced breast cancer. In cases of multiple pathological results, the definition of triple-negative breast cancer is based on the final molecular subtype result from the last biopsy pathology. (ER negativity: immunohistochemical staining in = 1.5 × 10^9/L; platelets >= 100 × 10^9/L; hemoglobin >= 90 g/L. b. Hepatic/renal: albumin >= 3.0 g/dL; total bilirubin = 60 mL/min (Cockcroft–Gault). c. Coagulation: PT and aPTT = 50 % by echocardiography. e. ECG: QTcF <= 470 ms. 8.Within 7 days before the first dose, women of reproductive potential must have a negative serum pregnancy test and agree to use effective contraceptive measures during the study drug administration and for 6 months after the last dose. For this protocol, women of reproductive potential are defined as sexually mature women who: 1) have not undergone hysterectomy or bilateral oophorectomy, and 2) have not experienced spontaneous menstruation cessation for a continuous period of 24 months (amenorrhea following cancer treatment does not exclude fertility) (i.e., menstruation has occurred at any time within the previous 24 consecutive months). For male patients with female partners of reproductive potential, they must agree to use effective contraceptive measures during the study drug administration and for 6 months after the last dose. 9.Voluntarily participate in this study, sign the informed consent form, demonstrate good compliance, and be willing to cooperate with visits and study-related procedures.
Exclusion criteria
Exclusion criteria: 1.Prior exposure to drugs targeting the same therapeutic target as the study treatment drug planned for administration. 2.Radiotherapy, chemotherapy, surgery, or other targeted immunotherapy for triple-negative breast cancer before enrollment. 3.Uncontrolled central nervous system metastases (symptomatic or requiring glucocorticoids or mannitol for symptom control). 4.Inflammatory breast cancer, bilateral breast cancer, or occult breast cancer. 5.History of clinically significant or uncontrolled cardiac disease within 6 months before the first dose, including congestive heart failure, angina pectoris, myocardial infarction, or ventricular arrhythmias. 6.Presence of severe concomitant diseases that, in the investigator's judgment, pose a significant risk to the patient's safety or ability to complete the study (including but not limited to severe hypertension not controlled by medication, severe diabetes, active infections, etc.). 7.Malignancy within 5 years before the first dose (except for cured basal cell carcinoma of the skin and cervical carcinoma in situ). 8.Active autoimmune diseases requiring systemic treatment within 2 years before the first dose, except for vitiligo, type 1 diabetes mellitus, residual hypothyroidism due to autoimmune thyroiditis requiring only hormone replacement therapy. 9.Receipt of live or attenuated vaccines within 4 weeks before the first dose of the study drug. 10.Known or suspected interstitial pneumonia. Presence of other moderate to severe respiratory diseases within 3 months before the first dose that may interfere with the detection or management of drug-related lung toxicity, including but not limited to idiopathic pulmonary fibrosis, organizing pneumonia/bronchiolitis obliterans, pulmonary embolism, severe asthma, severe chronic obstructive pulmonary disease (COPD), obstructive/restrictive lung diseases, etc.; as well as any autoimmune, connective tissue, or inflammatory diseases affecting the lungs, such as rheumatoid arthritis, Sjögren's syndrome, sarcoidosis, etc., or prior total lung resection surgery. 11.Known history of human immunodeficiency virus (HIV) infection. 12.Known history of hepatitis B or active hepatitis C virus infection. 13.Prior allergy to any component or excipient of the study drug planned for administration. 14.Other conditions deemed unsuitable for participation in the study by the investigator.
