• Primary aim of the study is to evaluate tolerability and safety of the treatment [ Time Frame: weekly the first four weeks thereafter biweekly ] [ Designated as safety issue: Yes ]
  

• Secondary aims: evaluation of treatment induced immune response and clinical response. [ Time Frame: after 8 and 16 weeks ] [ Designated as safety issue: No ]
  

Biological: tumor antigen loaded autologous dendritic cells

DC vaccination regime consists of primary 10 intradermal injections of 1-2 weeks interval (q1w x 4 → q2w x 6).

HLA-A2 positive patients are treated with p53, survivin and telomerase peptide-pulsed dendritic cells, and HLA-A2 negative patients are treated with allogeneic tumor lysate pulsed dendritic cells. 50 mg cyclophosphamide (Sendoxan®, Baxter A/S) is administered p.o. twice a day bi-weekly and 200 mg celecoxib (Celebra®, Pfizer) is given p.o. every day. From the 2nd vaccine, 2 MIU Interleukin-2 is administered s.c. on day 2-6.

Eligible patients receive vaccination with tumor antigen pulsed autologous monocyte-derived mature dendritic cells with a fixed interval. The dendritic cells are generated from leukapheresis products and frozen after antigen loading. HLA A2 positive patients are treated with PADRE and oncopeptide pulsed DC; p53, survivin and telomerase peptides.

HLA A2 negative patients are treated with KLH and tumorlysate pulsed DC; autologous or allogeneic. Each patient is given 6 immunizations with at least 5x106 peptide/lysate pulsed autologous DC. Vaccination 1-4 is given weekly and 4-6 at 2-week intervals. Those patients who exhibit stable disease, partial response or complete response after 6 injections will be given 4 more vaccinations at 2-week interval. The vaccine is applied by intradermal injection near the inguinal region. IL-2 2 MIU s.c. day 2-6, Cyclophosphamide (Sendoxan®, Baxter A/S) 50 mg twice a day bi-weekly and 200 mg Celecoxib (Celebra®, Pfizer) daily are used. Scans and re-staging tests are performed at scheduled intervals throughout the study.
