The purpose of this study is to assess the safety and activity of DC/PC3, a dendritic cell vaccine used as immunotherapy for prostate cancer. The vaccine is made with each participants' own immune cells obtained through blood donation. Dendritic cells are known to activate other immune cells such as T cells, that are able to mount an attack against cancer cells. The dendritic cell vaccine will be administered as injections every 2 weeks over a course of 2 months.

ex vivo generated autologous dendritic cells pulsed with apoptotic PC3 cells and pulsed with apoptotic PC3-M1 cells(control apoptotic cells) and pulsed with KLH (control antigen). maximum dose of DC/PC3 that we are able to generate from their initial leukaphereses product, up to a maximum of 10 x 106 DCs. Doses in the range of 105 to 10 x 106 DCs have been used clinically without toxicity

Toxicity
adverse events
Time frame: through week 29
Immunogenicity
The Tritiated thymidine proliferation assay is used to assess samples collected pre-treatment and those collected post-treatment; the outcome measure is the change in counts per minute (post-treatment counts minus pre-treatment counts).
Time frame: pre and post treatment
Clinical Response
Time frame: Post treatment
