PRIMARY outcome

Timeframe: 3 months

Population: Patients who withdrew without meeting the insufficient testosterone (T) suppression criteria were censored as of the time for last available T measurement prior to discontinuation. For the 40 mg group the 95% confidence interval around the time estimate was non-estimable and no statistical analysis is presented (the estimate was 14 days).

Figures in the table are Kaplan-Meier estimates of the time to meeting insufficient testosterone response. Insufficient testosterone response was defined as testosterone \>1.0 ng/mL at one visit or testosterone 0.5-1.0 at two consecutive visits.

SECONDARY outcome

Timeframe: 1, 3, 7, 14, 21, 28, 42 days

Population: Half participants in the 40 mg group were not castrated and the median was not calculated (no statistical anaylsis was made). Two participants out of 24 in the 80 mg, 1/24 in the 120 mg, and 3/24 in the 160 mg groups were not castrated. For the 160 mg group the 95% CI was non-estimable and no statistical anaylsis was made.

Time to testosterone castration was calculated as the number of days from dosing to the first scheduled visit when testosterone was less than 0.5 ng/mL. The figures in the table present the number of participants who were castrated after 1, 3, 7, 14, 21, 28, and 42 days.

Population: Participants who did not achieve the actual level of reduction were censored as of the time from dosing for the last available observation. In the 40 mg group only two participants reached a 50% reduction in PSA and the Kaplan-Meier estimate could not be calculated (ie no statistical analysis is presented for this group).

The time to 50% prostate-specific antigen (PSA) reduction from baseline was defined as the median number of days from dosing to the first visit where a 50% reduction in PSA level was reached.
