Study of Onivyde and 5-FU in Combination With Xilonix for Pancreatic Cancer With Cachexia

This study will prospectively evaluate advanced pancreatic adenocarcinoma patients. The intervention will be interleukin-1-alpha antagonist (Xilonix) in addition to standard chemotherapy. The first aim is to assess the safety and identify the maximum tolerated dose of Onivyde with 5-fluorouracil/folinic acid in combination with the study agent, Xilonix. The study will also create a repository of serum, tissue, and fecal specimens to investigate novel biomarkers related to cachexia with pancreatic adenocarcinoma and interleukin-1-alpha blockade. Lastly, the study will assess for a correlation between cachexia, activity, and PROs on domains of quality of life.
