Prostate Cancer Clinical Trials

Sequencing of Sipuleucel-T and ADT for Non-metastatic Prostate Cancer
A Randomized, Open-Label, Phase 2 Trial Examining the Sequencing of Sipuleucel-T and Androgen Deprivation Therapy in Men With Non-metastatic Prostate Cancer and a Rising Serum Prostate Specific Antigen After Primary Therapy
Status Conditions Phase Study ID
Closed Prostatic Neoplasm
Prostate Cancer
Prostatic Adenocarcinoma
Phase II NCT01431391

The main purpose of this study is to determine whether ADT started before or after sipuleucel-T leads to a better immune system response. This study will also evaluate the safety of sipuleucel-T treatment, immune system responses over time, the characteristics of sipuleucel-T, and changes in prostate specific antigen (PSA) values over time.
