Study Summary

To assess the efficacy and safety of 2 new formulations of leuprolide acetate 45 mg 6-month depot, Formulation A or Formulation B, for the treatment of patients with prostate cancer. A formulation will be deemed successful if the percentage of subjects with suppression of testosterone to \<= 50 ng/dL from Week 4 to Week 48 is not less than 87%, (the lower bound of the 2-sided 90% confidence interval), a protocol-specified criterion.

Primary Outcome

The percentage of subjects with testosterone suppression (\<= 50 ng/dL) from Week 4 to Week 48 was calculated by the Kaplan-Meier method for right-censored observations. Subjects who failed testosterone suppression were considered failures on the first day of a testosterone measurement (\>50 ng/dL). Subjects who prematurely discontinued without escaping and those who were successfully suppressed through Week 48 were censored at their last measured testosterone value (Day 337 to Day 340 at Week 4
