What was measured
Time to PSA progression was time interval between randomization \& first occurrence of PSA progression. PSA progression defined as: 1) PSA responders (\>50% decline from baseline PSA ≥10 ng/mL): increase of ≥25% (≥2 ng/mL) over nadir value, confirmed by second PSA ≥3 weeks later; 2) PSA non-responders (did not achieve \>50% decline from baseline PSA ≥10 ng/mL): increase of ≥25% (≥2 ng/mL) over baseline value, confirmed by second PSA ≥3 weeks later; 3) In participants not eligible for PSA response (baseline PSA \<10 ng/mL): (a) participants with baseline PSA \>0 ng/mL \& \<10 ng/mL: increase in PSA by 25% (≥2 ng/mL) above baseline level, confirmed by second PSA value ≥3 weeks apart; (b) participants with baseline value=0 ng/mL: post-baseline PSA value ≥2 ng/mL. Note (for 1-3): Rise in PSA in first 12 weeks was progression only if met definition above and was associated with other sign of DP or if it continued beyond 12 weeks. Analysis was performed by Kaplan-Meier method.
Analysis population: Analysis was performed on ITT population.

- Hazard ratio was estimated using a Cox Proportional Hazards regression model. The Cox proportional hazard model was adjusted by measurability of the disease at baseline, ECOG PS score at baseline, and region at the time of randomization.
