- Area Under the Curve of Testosterone Serum Concentration Between D1 and D169 (AUC1-169d); time frame: 1, 3, 5, 8, 15, 22, 29, 57, 85, 87, 113, 141 and 169 days post-dose; Area under the curve calculated from serum testosterone concentration taken at intervals between the first administration (Day 1) of the study drug and Day 169 after dosing. From the curve describing serum testosterone concentration levels (ng/mL) over time, the AUC was calculated using numerical integration methods. This value was log-transformed to more closely meet the assumption of the statistical method.<br/>- Area Under the Curve of Testosterone Serum Concentration Between D85 and D169 (AUC85-169d); time frame: 85, 87, 113, 141 and 169 days post-dose; Area under the curve calculated from serum testosterone concentration taken at intervals between Day 85 and Day 169 after dosing. From the curve describing serum testosterone concentration levels (ng/mL) over time, the AUC was calculated using numerical integration methods. This value was log-transformed to more closely meet the assumption of the statistical method.<br/>- Maximum Concentration of Serum Testosterone [Cmax] - Raw Data; time frame: 1, 3, 5, 8, 15, 22, 29, 57, 85, 87, 113, 141 and 169 days post-dose; Cmax was assessed as the maximum testosterone serum concentration between the first administration of the study drug and Day 169.<br/>- Maximum Concentration of Serum Testosterone [Cmax] - Log-transformed Data; time frame: 1, 3, 5, 8, 15, 22, 29, 57, 85, 87, 113, 141 and 169 days post-dose; Cmax was assessed as the maximum testosterone serum concentration between the first administration of the study drug and Day 169.<br/>- Time to Castration [Tcast] - Testosterone Level Less Than or Equal to 0.5 ng/mL; time frame: 12 weeks; tcast is the number of days between day of first administration of the study drug and the day the testosterone level reaches the limit of castration defined as testosterone level less than or equal to 0.5 ng/mL for the first time. Analysis of tcast was based on the Kaplan-Meier estimator.<br/>- Time to Castration [Tcast] - Testosterone Level Less Than 0.5 ng/mL; time frame: 12 weeks; tcast is the number of days between day of first administration of the study drug and the day the testosterone level reaches the limit of castration defined as testosterone level less than 0.5 ng/mL for the first time.
