Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine whether there is greater activity for carboplatin than a taxane standard of care (docetaxel) in women with ER-, PR- and HER2- breast cancer. The trial aims to recruit between 370 and 450 patients.
