Inclusion criteria
The subjects must meet all of the following conditions:
Adult female patients (aged 18 to 70 years) with metastatic breast cancer diagnosed by pathology or imaging; 2) Pathological confirmation of HER2 negative (definition: immunohistochemical result is 0 or + or ++ and in situ hybridization result is negative); 3) The patient's HRD test was positive (definition: BRCA1/2 mutation, or HRD score greater than or equal to 42 points); 4) HR+/HER2- patients who have received endocrine therapy during the metastasis stage; 5) Having received no more than two lines of chemotherapy (or ADC) regimens for metastatic breast cancer in the past; 6) Evaluation of anti-tumor treatment (including chemotherapy /HER2-ADC/TROP2-ADC) for 6-8 cycles to achieve clinical benefit (CR or PR) or SD for 24 weeks or more; 7) ECOG physical condition score ≤2 points, and the expected survival period is no less than 3 months; 8) At least one measurable lesion was found in the imaging examination within 2 weeks before enrollment. Or simple bone metastasis lesion; 9) At the time of enrollment, the previous treatment-related toxicity must be remitted to NCI CTCAE (Version 5.0) ≤1 degree (except for alopecia or other toxicities that the investigator deems to pose no risk to the patient's safety).

Exclusion Criteria
If a subject experiences any of the following situations, they will not be eligible to participate in this study:
1. Patients with HR+/ HER2-MBC who have not received endocrine therapy before;
2. Has not received any treatment for metastatic breast cancer;
3. Received more than two chemotherapy regimens for metastatic breast cancer;
4. Patients who are known to be allergic to the active ingredient or other ingredients of the investigational drug.
5. Pregnant or lactating women, and women of childbearing age who refused to take effective contraceptive measures during the study period.
6. Those with severe heart disease or discomfort, expected to be unable to tolerate chemotherapy, including but not limited to: fatal arrhythmia or higher-grade atrioventricular block, unstable angina pectoris, clinically significant valvular heart disease, electrocardiogram showing transmural myocardial infarction, uncontrollable hypertension;
7. Any other circumstances where the researcher deems the patient unsuitable for participation in this study, any concomitant diseases or conditions that may interfere with participation in the study, or any serious medical conditions that may affect the safety of the subjects (such as uncontrollable heart disease, hypertension, active or uncontrollable infection, active hepatitis B virus infection).
