- PSA increment and absolute PSA response [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]PSA response evaluation at 12 weeks and follow up response evaluation at 21 weeks
- Time to Progression [ Time Frame: DC Injection to time to progression or death ] [ Designated as safety issue: No ]

Biological: Autologous dendritic cell
CreaVax-PC consisted of antigen (PSA, PAP and KLH) primed dendritic cell is an investigational product designed to activate a man's immune response, so they can detect prostate cancer cells and initiate an immune response against prostate cancer antigens.
If patients decide to participate and are eligible, they will be enrolled in the study and will receive active product (CreaVax-PC). In detail, patients will receive CreaVax-PC injection at intervals of 3 weeks, maximum 6 times during 21 weeks. PSA increase rate is a primary evaluation variables and tumor suppression effect is secondary evaluation variables. We also evaluate time to progression, overall survival and immune response.
