Materials and Methods Patients with human epidermal growth factor receptor 2\u2013negative germline BRCA1\/2-mutated advanced breast cancer who received prior chemotherapy were randomized 2:1 to talazoparib 1 mg\/day or chemotherapy (physician\u2019s choice). Primary endpoint was progression-free survival (PFS) per independent central review in the intent-to-treat (ITT) population. This post-hoc analysis evaluated efficacy\/safety endpoints in the ITT population of patients enrolled in Asian regions. Results Thirty-three patients were enrolled at Asian sites (talazoparib, n=23; chemotherapy, n=10). Baseline characteristics were generally comparable with the overall EMBRACA population. 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 (62.5% [95% CI, 35.4, 84.8] vs. 25.0% [95% CI, 3.2, 65.1]). Median overall survival was 20.7 months (95% CI, 9.4, 40.1) versus 21.2 months (95% CI, 2.7, 35.0) months (HR, 1.41 [95% CI, 0.49, 4.05]). In Asian patients, fewer grade 3\/4 adverse events (AEs), serious AEs (SAEs), grade 3\/4 SAEs, and AEs resulting in dose reduction\/discontinuation occurred with talazoparib than chemotherapy; for talazoparib, the frequency of these events was lower in Asian patients versus overall EMBRACA population. Conclusion In this subgroup analysis, talazoparib numerically improved efficacy versus chemotherapy and was generally well tolerated in Asian patients, with fewer grade 3\/4 TEAEs, SAEs, and TEAEs leading to dose modification vs. the overall EMBRACA population.<\/jats:p>","DOI":"10.4143\/crt.2020.1381","type":"journal-article","created":{"date-parts":[[2021,3,24]],"date-time":"2021-03-24T04:42:31Z","timestamp":1616560951000},"page":"1084-1095","update-policy":"https:\/\/doi.org\/10.4143\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Talazoparib
