Brief Summary

The primary purpose of the study is to determine if a new sustained-release 45 mg (depot) formulation of leuprolide acetate will reduce serum testosterone levels to and maintain them at medically castrate levels in subjects with prostatic adenocarcinoma.

Detailed Description

The primary purpose of the study is to determine if a new sustained-release 45 mg (depot) formulation of leuprolide acetate administered once every 26 weeks for 1 year, will lower testosterone levels to and maintain them at medically castrate levels in subjects with prostatic adenocarcinoma.
