Recruitment Details

Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Participants who successfully completed and showed maintenance of luteinizing hormone suppression through the 6-month treatment period of the lead-in study L-CP07-167 (NCT00635817) received the same treatment in this study that they were previously assigned in the lead-in study.

Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
At the end of the Treatment Period, participants who completed the study or prematurely discontinued from the study could enter the Safety Follow-Up Period.

Reporting Groups

	Description
Leuprolide Acetate 3M Depot 11.25 mg	Twelve intramuscular injections of leuprolide acetate for depot suspension 11.25 mg administered 3 months apart during the Treatment Period.
