Primary Outcome Measures:
  • To establish the maximally tolerated dose (MTD) and dose limiting toxicities (DLT) of intratumoral autologous dendritic cell vaccination in combination with OK-432 [ Time Frame: 2 years ]

Secondary Outcome Measures:
  • To determine the overall response rate for this regimen as determined by overall and disease-free survival. [ Time Frame: 2 years ]
  • To evaluate the immune response of patients treated with this regimen based on the presence and characterization of tumor-infiltrating white blood cells [ Time Frame: 2 years ]

Estimated Enrollment: 20
Study Start Date: November 2003
Estimated Study Completion Date: November 2012
Estimated Primary Completion Date: November 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: dendritic cells Biological: dendritic cells, OK-432
Single Group Assignment

Detailed Description:
The prognosis of pancreatic cancer is extremely poor even with extensive surgery, and development of new treatment modalities is much-expected for cure of this disease. Dendritic cells (DCs) immunotherapy is expected favorable outcome when it is approached directly to the cancer tissue. To evaluate safety and immunological responses, we conducted a phase I/II study of intra-tumor DCs immunotherapy for pancreatic cancer patients.
