Dendritic cells (DCs) are the professional antigen-presenting cells of the immune system. As such they are currently used in clinical vaccination protocols in cancer patients, and both immunological and clinical responses have been observed. Several subsets of dendritic cells have been characterized in the peripheral blood. One such subset is referred to as plasmacytoid dendritic cells (PDC). To date PDC have not been evaluated for their capability to induce anti-tumor immune responses in patients. For this reason the investigators will perform a safety and efficacy study with PDC in stage IV melanoma patients.

Further study details as provided by Radboud University:

Primary Outcome Measures:
  • intervention-related toxicity [ Time Frame: Within the first 6 months ] [ Designated as safety issue: Yes ]
    all adverse events within a time frame of 3 weeks after the last vaccination will be scored according to Common Terminology Criteria for Adverse Events (CTCAE)Version 4.0

Secondary Outcome Measures:
  • Immunological response [ Time Frame: Within the first year ] [ Designated as safety issue: No ]
    The immunological response will be determined by tetramer sampling of skin-test derived lymphocyte cultures and peripheral blood after vaccination
