Trial ID: NCT02243371

Purpose

The primary objective of this study is to compare the overall survival (OS) of subjects with previously treated metastatic pancreatic cancer treated with cyclophosphamide (CY)/nivolumab/GVAX pancreas vaccine followed by nivolumab/CRS-207 (Arm A) to subjects treated with CY/GVAX pancreas vaccine followed by CRS-207 (Arm B).
