Fluorizoparib Plus Apatinib Versus Chemotherapy in HRD-positive, HER2-negative Advanced Breast Cancer

Summary

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.
