Overview
The study is a randomized, open-label, multicenter phase II clinical trial of the efficacy and safety of fluzopanib in the adjuvant treatment of early breast cancer using germline mutations in homologous recombination repair pathway genes. Study design Patients will be randomized into 2 groups in a 1:1 ratio after enrollment: Experimental group: fluzoparib, specific: fluzoparib 100 mg bid for 1 year. As well as the standard of care selected by the physician (in case of TNBC, combination therapy includes but is not limited to immunotherapy or capecitabine; in case of HR +, combination therapy includes but is not limited to endocrine therapy or CDK4/6 inhibitors). Control group: Doctors' choice of standard treatment (in case of TNBC, combination therapy includes but is not limited to immunotherapy or capecitabine; in case of HR +, combination therapy includes but is not limited to endocrine therapy or CDK4/6 inhibitors)
