This phase Ib / II trial studies the best dose and side effects of siltuximab and how well it works in combination with spartalizumab in treating participants with pancreatic cancer that has spread to other places in the body. Monoclonal antibodies, such as siltuximab and spartalizumab, interfere with the ability of tumors cells to grow and spread.


I. Determine the recommended phase II dose for the combination of spartalizumab and siltuximab.

I. Define the toxicity profile of the combination of the recommended phase II dose of spartalizumab and siltuximab.
II. Evaluate the activity of the combination of spartalizumab and siltuximab in previously treated patients with pancreatic cancer.

I. Evaluate the effect of the combination on the immune profile in the serum and in tumor biopsies.

OUTLINE: This is a dose-escalation study of siltuximab.

Participants receive spartalizumab intravenously (IV) over 30 minutes on day 1 and siltuximab IV over 1 hour on day 1. Courses repeat every 3 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, participants are followed up at 30, 60, 90, 120, and 150 days, then every 12 weeks thereafter.
