Brief summary
The study aim to show if vaccination with autologous dendritic cells pulsed with onco-peptides in combination with adjuvant cytokine can induce a measurable immune response in patients with metastatic breast cancer, and to evaluate the clinical effect (objective response rate) of the vaccination regime.
Detailed description
HLA A2 positive patients are treated with PADRE and oncopeptide pulsed DC; p53, survivin and telomerase peptides. 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 either intranodal or intradermal injection near the inguinal region. For adjuvant used IL-2 2 MIU sc. day 2-6. Scans and re-staging tests are performed at scheduled intervals throughout the study.
