What was measured

The cumulative probability of testosterone recovery back to \> 280 ng/dL (lower limit of the normal range), back to ≥ 50 ng/dL (definition of castration), and back to \> 280 ng/dL or baseline at 90 days after drug discontinuation was assessed. The rate was estimated for each treatment group using the Kaplan-Meier method and reported as percentage of participants.

Analysis population: All randomized participants who received at least 1 dose of study drug and were followed in the testosterone recovery phase.
