Primary Outcome Measures:
  • The percentage of responders who attain and maintain castrate levels of serum testosterone [ Time Frame: From Day 28 to Day 168. ]

Secondary Outcome Measures:
  • Safety as shown through laboratory parameters [ Time Frame: Day 0 - Day 168 ]
    Hematology, chemistry and urinalysis

  • Leuprolide serum profiles following administration study drug product. [ Time Frame: Day 0 - Day 168 ]
    Leuprolide levels (ng/dL) measured at designated time points to determine a pharmacokinetic profile for the product.

  • Safety as shown through reported adverse events [ Time Frame: Day 0 -168 ]

Enrollment: 201
Study Start Date: April 2007
Study Completion Date: August 2008
Primary Completion Date: August 2008 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Leuprolide Acetate for Injectable Suspension
    Sustained release injectable microspheres, 22.5 mg, one injection every 84 days, 3-month product
Detailed Description:
This study is an open-label, multi-center study in which a minimum of 165 patients will receive one (1) of three (3) lots of Oakwood Laboratories' Leuprolide Acetate for Injectable Suspension 22.5 mg for two cycles. A subset of patients (minimum of 12) will be assigned to each lot (A, B or C) and will have additional blood sampling to characterize leuprolide release kinetics for each dose administered.
