EiSai’s Halaven approved in China for treatment of locally advanced or metastatic breast cancer

EiSai announced that China approved Halaven (eribulin mesylate) for the treatment of locally advanced or metastatic breast cancer, for patients who were treated with two treatment including an anthracycline and a taxane. The approval was received from by National Medical Products Administration (NMPA).


The approval was based on study 304, a Phase 3 open label, randomised clinical trial. In the trial the safety and efficacy of Halaven was compared with vinorelbine, in patients previously treated with chemotherapy regimens, including an anthracycline and a taxane. Halaven showed statistically significant improvement in the progression free survival compared to vinorelbine.


The most common adverse events include reduction in the number of white blood cells, neutrophils, increase in aspartate aminotransferase, increased alanine aminotransferase and anemia.
