Summary
Brief summary (as posted)
The main purpose of this study was to determine whether ADT started before or after sipuleucel-T led to a better immune system response. This study also evaluated the safety of sipuleucel-T and ADT treatment, immune system responses over time, the characteristics of sipuleucel-T, and changes in prostate specific antigen (PSA) values over time.

- Arm 1: Sipuleucel-T followed by ADT
- description
- Arm 1: Subjects received one infusion of sipuleucel-T every two weeks for a total of three infusions. Two weeks after the third sipuleucel-T infusion, subjects started ADT with 45 mg leuprolide acetate depot injection (Eligard® 45 mg). An additional leuprolide acetate injection was administered at 6 months after the first injection for a total of 2 injections and 12 months of ADT.

- description
- Arm 2: Subjects started ADT with 45 mg leuprolide acetate depot injection (Eligard® 45 mg) 12 weeks before infusion 1 of sipuleucel-T. An additional leuprolide acetate injection was administered at 6 months after the first injection for a total of 2 injections and 12 months of ADT. Twelve weeks after the initial leuprolide 45 mg depot injection, subjects began one infusion of sipuleucel-T every two weeks for a total of three infusions.
