In this study, we will prospectively evaluate advanced pancreatic adenocarcinoma patients with cachexia, who are receiving enteral feeding, with a peptide based diet (medical food), through a jejunal or gastrojejunal feeding tube. We plan to collect serum samples routinely and establish a cohort of patients with this clinical syndrome. Our aims are to establish the feasibility and efficacy of enteral nutrition and its relationship to meaningful clinical outcomes. Furthermore, we will assess for a correlation between cachexia, activity, and patient reported outcomes on domains of quality of life in an optional activity tracker sub-study.
