Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Originally, the study was planned for 1696 participants to be randomized. However, enrollment was not met and in September 2007, the Steering Committee decided to stop recruitment. Only participants who had signed Informed Consent by then and met eligibility criteria were randomized. 228 participants were randomized to this study.

  Description
Docetaxel / Leuprolide Acetate - Immediate Treatment (I-CHT) Participants administered 75 mg/m^2 docetaxel every three weeks (q3w) for 6 cycles in combination with 22.5 mg leuprolide acetate every 3 months for 18 months immediately following prostatectomy.
Leuprolide Acetate - Immediate Treatment (I-HT) Participants administered 22.5 mg leuprolide acetate every 3 months for 18 months immediately following prostatectomy.
Docetaxel / Leuprolide Acetate - Deferred Treatment (D-CHT) Participants in whom treatment was deferred from randomization until first progression - i.e. PSA progression and/or radiologically or histologically documented progression. Participants were treated with 75 mg/m^2 docetaxel every three weeks (q3w) for 6 cycles in combination with 22.5 mg leuprolide acetate every 3 months for 18 months.
Leuprolide Acetate - Deferred Treatment (D-HT) Participants in whom treatment was deferred from randomization until first progression - i.e. PSA progression and/or radiologically or histologically documented progression. Participants were treated with 22.5 mg leuprolide acetate every 3 months for 18 months.

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
The study had difficulties in meeting enrollment goals within a reasonable time frame. The final sample size allowed for the safety analyses but was underpowered for drawing conclusions regarding efficacy and quality of life (QoL) endpoints.
