This is an open-label, multicenter phase II study evaluating the combination of eribulin (0.88 mg/m2) plus gemcitabine (1000 mg/m2) on days 1 and 8 of a 21-day cycle as either first- or second-line treatment of locally advanced or metastatic TNBC....the clinical benefit rate was 57.7% (90% CI 45.4-69.3) in wild-type patients and only 26.7% (90% CI 9.7-51.1) in BRCA-mutated ones (P = 0.043). Similarly, subjects with BRCA pathogenic variants were associated with significantly worse response duration, PFS, and OS than non-carriers...
