研究概览
简要总结
This study will assess the feasibility and safety of vaccination with increasing doses of xenogenic DNA administered intradermally in combination with electroporation in patients with relapse of prostate cancer. The DNA encodes prostate specific antigen (PSA) from Rhesus Macaque (Macaca mulatta), a protein that is 89% homologous to human PSA. The study will also assess the safety and functionality of the DERMA VAX™ (Cyto Pulse Sciences) DNA vaccine delivery system.

- •Carrier of HIV, HBV, or HCV.
- •Immunosuppressed (post splenectomy, post stem cell transplantation) or on immunosuppressive therapy other than inhaled or replacement corticosteroids.
- •Any other major illness or peripheral blood vein status that, in the investigator's judgement, will substantially increase the risk associated with sampling or participation in this study.
