Summary

This study will be looking at whether combining cyclophosphamide, pembrolizumab (an antibody that blocks negative signals to T cells), GVAX (pancreatic cancer vaccine), and SBRT (focused radiation) is effective (anti-tumor activity) and safe in patients with locally advanced pancreatic cancer.

Conditions

Interventions

DRUG

Cyclophosphamide

200 mg/m2 is to be administered as a 30 minute IV infusion one day prior to GVAX Pancreas Vaccine every 21 days for a total of 8 doses. In the extended treatment phase, eligible patients may receive 200 mg/m2 as a 30 minute IV infusion one day prior to GVAX Pancreas Vaccine every 6 months for an additional 4 doses.

DRUG

GVAX Pancreatic Cancer Vaccine

2.5E8 cells of each cell line (Panc 6.03/Panc 10.05) for a total of 5E8 cells is to be administered one day after CY and pembrolizumab for a total of 8 doses. In the extended treatment phase, eligible patients may receive 2.5E8 cells of each cell line (Panc 6.03/Panc 10.05) for a total of 5E8 cells administered one day after CY every 6 months for an additional 4 doses.

DRUG

Pembrolizumab

200 mg will be administered as a 30 minute IV infusion one day prior to the GVAX pancreas vaccine every 21 days for a total of 8 doses. In the extended treatment phase, eligible patients may receive 200 mg as a 30 minute IV infusion every 21 days for an additional 9 doses.

RADIATION

SBRT

Patients will receive SBRT (6.6 Gy for 5 days) with the second dose of combined immunotherapy (CY/Pembrolizumab/GVAX Pancreas Vaccine).
