Overview
Patients with pancreatic cancer (pancreatic ductal adenocarcinoma (PDAC) and pancreatic neuroendocrine tumor (NET)) commonly experience fat malabsorption due to exocrine pancreatic insufficiency (EPI) and leads to gastrointestinal (GI) symptoms, malnutrition, weight loss, and reduced quality of life (QoL). Current standard treatment, pancreatic enzyme replacement therapy (PERT), is limited by suboptimal adherence, high cost, and partial effectiveness to prevent fat malabsorption. The objective of the study is to assess the feasibility and maintenance of lipid absorption function of a structured lipid medical food (SLMF; Encala®) powder in subjects with PDAC and NET with EPI.
Description
This study is a prospective, single-arm pilot clinical trial designed to evaluate the feasibility, tolerance, safety, and potential effects of a structured lipid medical food (Encala®) in adult patients with pancreatic cancer, including pancreatic ductal adenocarcinoma (PDAC) and pancreatic neuroendocrine tumors (NET), who are at risk for exocrine pancreatic insufficiency (EPI) and fat malabsorption. Fat malabsorption is common in patients with pancreatic cancer due to impaired pancreatic enzyme function, leading to gastrointestinal symptoms, malnutrition, weight loss, and reduced quality of life. The structured lipid medical food evaluated in this study is designed to improve fat absorption without requiring pancreatic lipase or bile acids, potentially addressing a critical gap in nutritional support for this population.
This study will enroll approximately 18 adult participants recruited through the Penn Pancreatic Cancer Research Center. Participants will receive the study intervention over an 8-week period, during which they will consume 4-5 daily doses of the structured lipid medical food (approximately 400-500 kcal/day), mixed with preferred foods, beverages, or enteral feeding formulations.
Participants will undergo study assessments at baseline, 4 weeks, and 8 weeks. These assessments will include evaluation of gastrointestinal symptoms, nutritional status, dietary intake, body composition, and physical function. Laboratory measures, including plasma fatty acids and nutritional biomarkers, will be collected to assess changes in fat absorption and nutritional status. A malabsorption blood test (MBT) will also be used to evaluate intestinal fat absorption.
The primary outcomes of this study are feasibility, tolerance, and safety of the intervention. Secondary outcomes include changes in gastrointestinal symptoms, body weight, nutritional biomarkers, and measure of fat absorption (MBT) at baseline.
Findings from this pilot study will provide preliminary data on the feasibility and potential clinical benefits of this nutritional intervention and will inform the design of future larger-scale studies aimed at improving nutritional management and quality of life in patients with pancreatic cancer.
