What was measured

Time to SSE was defined as the time duration (in months) between the date of randomization and the date of occurrence of the first SSE. Analysis was performed by Kaplan-Meier method.

Analysis population: Analysis was performed on ITT population.

Groups in this outcome

Cabazitaxel

Participants received Cabazitaxel 25 mg/m\^2 IV infusion for over 1 hour on Day 1 of each 3 week treatment cycle in combination with Prednisone 10 mg orally once daily and primary prophylactic G-CSF as per investigator decision, until radiographic disease progression, unacceptable toxicity, or participant's refusal of further study treatment (median duration = 22 weeks).

Abiraterone Acetate or Enzalutamide

Participants received either abiraterone acetate 1000 mg orally once daily from Day 1 to Day 21 of each 3 week treatment cycle in combination with prednisone 5 mg orally twice daily; or enzalutamide 160 mg orally once daily continuously from Day 1 to Day 21 of each 3 week treatment cycle, until radiographic disease progression, unacceptable toxicity, or participant's refusal of further study treatment (median duration = 12.5 weeks).
