Rockefeller University
ClinicalTrials.gov Identifier:
NCT00345293
First received: June 26, 2006
Last updated: September 19, 2013

  Purpose

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.

Arms Assigned Interventions
Experimental: DC/PC3 vaccine
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)
Biological: autologous dendritic cell vaccine (DC/PC3)
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 leukapheresate, 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
