Summary
Brief summary (as posted)
This is a Phase III clinical trial for patients with a specific type of advanced breast cancer that is HER2-negative and has a biomarker called "Homologous Recombination Deficiency (HRD)-positive." The study aims to compare the effectiveness and safety of two treatment strategies: Experimental Group: Patients will first receive 6 cycles of standard chemotherapy or antibody-drug conjugate (ADC) therapy chosen by their doctor. After completing these 6 cycles, they will switch to a combination of two oral targeted drugs: Fluorizoparib and Apatinib, as long-term maintenance therapy. Control Group: Patients will continue to receive their doctor's choice of standard chemotherapy or ADC therapy without switching to the targeted drug combination. Patients will be randomly assigned (like flipping a coin) to one of the two groups.

- Sequential Fluorizoparib + Apatinib after Chemotherapy/ADC
- description
- This is the experimental arm. Participants receive a two-phase sequential treatment strategy: Induction Phase: 6 cycles of investigator-selected chemotherapy or ADC therapy. Maintenance Phase: Participants who complete induction without disease progression switch to long-term oral maintenance therapy with the combination of Fluorizoparib and Apatinib. Treatment continues until disease progression, unacceptable toxicity, withdrawal, or death.

- Physician's Choice Chemotherapy/ADC Regimen
- description
- This is the control arm intervention. Participants receive continuous treatment with a standard chemotherapy regimen or an Antibody-Drug Conjugate (ADC) selected by the investigator from protocol-specified options (e.g., eribulin, vinorelbine, gemcitabine, capecitabine, sacituzumab govitecan, or trastuzumab deruxtecan). Treatment is administered intravenously or orally according to the standard schedule of the chosen agent and continues without a planned switch to the oral targeted combination therapy, until disease progression, unacceptable toxicity, withdrawal of consent, or death.
