Brief Summary:
This trial is to evaluate the safety and effectiveness of autologous type-1 polarized dendritic cell vaccines (patients' autologous DC1s loaded with multiple antigens CTL epitope peptide complexes), after radical resection for patients with stage III-IV renal cell carcinoma. Autologous cytotoxic of T lymphocytes (CTL) induced by type-1 polarized dendritic cells (DC1) loaded with MAGE-3/MAGE-4/survivin/ her2 /COX-2 CTL epitope peptides .

Condition or disease Intervention/treatment Phase
Renal Cell Carcinoma Biological: DC1-CTL Phase 1 Phase 2

Detailed Description:
All participants judged to have RCC and considered able to conduct apheresis. Immunotherapy regimen will include subcutaneous injection (3million cells) DC1 vaccines and intravenous infusion CTL cells. On day 0,participants conduct apheresis for 50-60ml. PBMCs were separated from paiticipants by density gradient centrifugation. The adherent cells were initiated into DC followed by the particular combination of cytokines to promote DC type-1 polarization. On day 6, the synthetic CTL epitope peptides were added into the culture for autologous DCs for another 24h. Then one half of DC1s were resuspended in 1ml normal saline for clinical multi-point injection near lymph nodes. The remaining half were cocultured with autologous T cells for another 7 days to induce antigen-specific CTL cells. The applied TAAs included MAGE-3/ MAGE-4/ survivin/ her2 /ect. On day 14, after quality inspection qualified, CTL cells were harvested and resuspended in 100ml normal saline and 2% autologous plasma for clinical intravenous infusion, once a day for 3 days. In order to avoid overlap between experimental immunotherapy and potential adjuvant chemotherapy, chemotherapy may start at least 2 weeks after completion of the cycle of immunotherapy. The 2nd cycle of immunotherapy may start at least 4weeks after the completion of chemotherapy.
