An open-label study of Sipuleucel-T (Provenge) is ongoing at 8 centers across the USA. This is a Phase 2 Study enrolling men with Metastatic Castrate Resistant Prostate Cancer (CRPC).

The aim of this study is to measure the immune responses to treatment with sipuleucel-T (Provenge). All participants will receive the drug.

“Subjects will receive the investigational product, sipuleucel-T, at approximately 2-week intervals, for a total of 3 infusions. The study will evaluate the safety of and magnitude of the immune responses to treatment with sipuleucel-T. All subjects will be followed for 30 days following the last infusion of sipuleucel-T. The study is also available to placebo subjects who participated in the D9902B study.”
