Study With CY, Pembrolizumab, GVAX Pancreas Vaccine, and SBRT in Patients With Locally Advanced Pancreatic Cancer

A Phase II Study of GM-CSF Secreting Allogeneic Pancreatic Cancer Vaccine in Combination With PD-1 Blockade Antibody (Pembrolizumab) and Stereotactic Body Radiation Therapy (SBRT) for the Treatment of Patients With Locally Advanced Adenocarcinoma of the Pancreas

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

• Pancreatic Cancer

Interventions

Type	Name	Description
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).
