I. To determine the objective response rate (ORR) using Response Evaluation Criteria for Solid Tumors (RECIST 1.1) in two cohorts of subjects with previously treated metastatic pancreatic cancer: Arm A treated with cyclophosphamide (CY)/nivolumab/ipilimumab/allogeneic GM-CSF-secreting lethally irradiated pancreatic tumor cell vaccine (GVAX pancreas vaccine) followed by nivolumab/ipilimumab/live-attenuated listeria encoding human mesothelin vaccine CRS-207 (CRS-207) and Arm B treated with nivolumab/ipilimumab/CRS-207.
I. To assess safety and characterize toxicities of each vaccine treatment regimen when combined with anti-PD-1 and anti-CTLA-4 blockade in subjects with metastatic pancreatic adenocarcinoma.
I. To assess the overall survival (OS).
II. To assess progression free survival (PFS), duration of response (DOR), and time to progression (TTP) by RECIST 1.1.
III. To measure tumor marker kinetics (CA 19-9) in subjects receiving treatment and correlate with OS, PFS, and best overall response.
IV. To assess the ORR, PFS, and DOR by immune-related response criteria (irRC).
V. To collect peripheral blood mononuclear cells (PBMC), plasma, and serum to identify potential therapeutic targets, biomarkers and predictors of response (OS, PFS and best overall response) and autoimmune toxicity.
VI. To collect archived tissue and pre- and post-treatment biopsies to test for predictors of response (OS, PFS, and best overall response) and future targets for combinatorial therapy.
VII. To collect stool and oral wash samples pre- and post-treatment to identify candidate gut microbial biomarkers and predictors of response (OS, PFS and best overall response).
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM A: Patients receive nivolumab IV over 30 minutes on day 1. Patients also receive cyclophosphamide intravenously (IV) over 30 minutes on day 1 of cycles 1-2, ipilimumab IV over 30 minutes on day 1 of cycles 1, 3, and 5, GVAX pancreas vaccine intradermally (ID) on day 2 of cycles 1-2, and CRS-207 IV over 1 hour on day 2 of cycles 3-6. Treatment repeats every 3 weeks for 6 cycles in the absence of disease progression or unacceptable toxicity.
ARM B: Patients receive nivolumab IV over 30 minutes on day 1. Patients also receive ipilimumab IV over 30 minutes on day 1 of cycles 1, 3, and 5 and CRS-207 IV over 1 hour on day 2 of cycles 1-6. Treatment repeats every 3 weeks for 6 cycles the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at day 100 and every 3 months thereafter.
