Measure
Sipuleucel-T
All subjects randomized to receive sipuleucel-T. Autologous peripheral blood mononuclear cells, including antigen presenting cells, that have been activated in vitro with a recombinant fusion protein, PAP-GM-CSF. Treatment consist of 3 doses administered approximately 2 weeks apart.
Placebo
All subjects randomized to receive placebo. Approximately one-third of the autologous quiescent APCs prepared from a single leukapheresis procedure. A course of therapy consists of 3 complete doses given at approximately 2-week intervals.
