  1. Data cut-off 9 December 2016; *BRCA mutation confirmed using BRACAnalysis CDx® (Myriad Genetic Laboratories, Inc); Six patients did not receive study treatment in the global population, one of whom was in the Asian subgroup. No patients in China received eribulin as chemotherapy TPC because it did not have regulatory approval in that country. BRCAm, BRCA mutation; ECOG, Eastern Cooperative Oncology Group; ER+, oestrogen receptor positive; NA, not applicable; PR+, progesterone receptor positive; TNBC, triple-negative breast cancer; TPC, treatment of physician’s choice.
