Talazoparib Versus Chemotherapy in Patients with HER2-negative Advanced Breast Cancer and a Germline BRCA1/2 Mutation Enrolled in Asian Countries: Exploratory Subgroup Analysis of the Phase III EMBRACA Trial
Excerpt:Patients with HER2-negative germline BRCA1/2-mutated advanced breast cancer who received prior chemotherapy were randomized 2:1 to talazoparib 1 mg/day or chemotherapy (physician's choice)….In Asian patients, median PFS was 9.0 months (95% confidence interval [CI] 3.0, 15.2) for talazoparib and 7.1 months (95% CI, 1.2, not reached) for chemotherapy (hazard ratio [HR] 0.74 [95% CI, 0.22, 2.44]). Objective response rate was numerically higher for talazoparib vs. chemotherapy.

Efficacy and safety of talazoparib in Japanese patients with germline BRCA-mutated locally advanced or metastatic breast cancer: results of the phase 1 dose-expansion study
Excerpt:This phase 1, open-label, multicenter study evaluated talazoparib monotherapy in Japanese patients with germline BRCA mutations and HER2-negative locally advanced or metastatic breast cancer...Confirmed ORR was 57.9% (11/19; 90% confidence interval [CI] 36.8-77.0). Stable disease was observed in 36.8% (7/19) of patients. Per investigator assessment, median PFS was 7.2 months (95% CI 4.1-not estimable) and 12-month OS rate was 84.7% (90% CI 57.5-95.1)....In Japanese patients with gBRCA mutations and locally advanced or metastatic breast cancer, talazoparib monotherapy was generally well tolerated and resulted in clinically meaningful ORRs.
