Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment

165 patients signed informed consent but were not randomized and considered as screen failure.

Intention to Treat Population (ITT or randomized patients): 755 patients (377 mitoxantrone, 378 cabazitaxel).

Safety population (treated patients): 742 patients (371 mitoxantrone, 371 cabazitaxel) (Patients not treated: 6 mitoxantrone, 7 cabazitaxel).

Reporting Groups
  Description
Mitoxantrone + Prednisone mitoxantrone 12 mg/m^2 (Day 1) by intravenous (IV) every 3 weeks, and prednisone 10 mg orally given daily
