...phase II trial was to evaluate the activity and safety of cabazitaxel as 2nd-line treatment, given on day 1 of a 21-day cycle, in patients with HER-2 negative metastatic breast cancer...In the 77 patients with evaluable treatment response, the ORR was 24.7% (1 complete and 18 partial responses). The disease-control rate was 58.4%, while the median DOR was 5.6 months (range 0.7-51.3). Within a median follow-up of 32.2 months, the median PFS was 3.7 months (95% CI 2.23-4.36), whereas the median OS was 15.2 months (95% CI 11.21-21.54).
