Dendritic Cell Vaccine and Chemotherapy for Patients With Pancreatic Cancer

This is a single center, exploratory pilot safety, open label, phase I trial that will evaluate the combination of DC vaccination in 2 groups of patients when combined with chemotherapy including FOLFIRINOX and gemcitabine+nab-paclitaxel in patients with pancreatic cancer. The investigations will accrue 20 evaluable subjects over 20 months with 10 patients in each group. Subjects will be assigned to group 1 or group 2 according to the subject's disease stage. The protocol will be conducted in two stages: The 1st 3 patients will be enrolled to either group to receive DC vaccinations combined with standard chemotherapy. A safety analysis will be performed after the first 3 patients have completed 6 vaccines. If no vaccine dose-limiting toxicity occurs in any of the 3 patients then the study will proceed with stage 2. Stage 2 will include the enrollment of the remaining 17 patients.
