Further study details as provided by Samsung Medical Center:

Primary Outcome Measures:
  • PSA increment and absolute PSA response [ Time Frame: 12 weeks ]
    PSA response evaluation at 12 weeks and follow up response evaluation at 21 weeks


Secondary Outcome Measures:
  • Time to Progression [ Time Frame: DC Injection to time to progression or death ]
  • Overall Survival [ Time Frame: Patients will be followed until death ]
  • Immune Response(DTH response, Interferon-gamma Elispot assay, proliferation assay, ELISA) [ Time Frame: weeks 0, 12, 21 ]
  • Clinical response [ Time Frame: week 0, 12, 21 ]
    Clinical course of participants as measured by bone scans and CT


Enrollment: 12
Study Start Date: July 2006
Study Completion Date: May 2010
Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Biological: Autologous dendritic cell
    Autologous dendritic cells pulsed with prostate cancer antigen and KLH
    Other Name: CreaVax-PC
Detailed Description:

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.
