简要总结
RATIONALE: Vaccines made from gene-modified tumor cells may help the body build an immune response to kill tumor cells. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Cetuximab may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving vaccine therapy together with cyclophosphamide and cetuximab may kill more tumor cells.
PURPOSE: This phase II trial is studying how well vaccine therapy works when given together with cyclophosphamide and cetuximab in treating patients with metastatic or locally advanced pancreatic cancer.
详细描述
OBJECTIVES:
Primary
- Determine the safety of pancreatic tumor vaccine, cyclophosphamide, and cetuximab in patients with metastatic or locally advanced adenocarcinoma of the pancreas.
Secondary
- Determine the overall, progression-free, and event-free survival of patients treated with this regimen.
- Correlate specific in vivo parameters of immune response (e.g., mesothelin, prostate stem cell antigen [PSCA], mutated k-ras-specific T-cell responses) with clinical response in patients treated with this regimen.
- Correlate downstream targets of epidermal growth factor receptor (EGFR) signaling (e.g., intratumor expression of Akt, Stat 3 and 5, mesothelin, mutated k-ras, and PSCA) with inhibition by cetuximab in patients treated with this regimen.
- Correlate inhibition of EGFR signaling (e.g., Stat 3 and 5) with improved specific mesothelin, PSCA, and mutated k-ras-specific T-cell responses in patients treated with this regimen.
