Pea Protein Oral Nutrition Supplement for the Reduction of Gastrostomy Tube Placement Rate in Patients With Locally Advanced Head and Neck Cancer Undergoing Chemoradiation Therapy

PRIMARY OBJECTIVE: I. To determine the therapeutic G-tube placement rate during chemoradiation. SECONDARY OBJECTIVES: I. To determine percent weight change during and following treatment. II. To determine body mass index (BMI) changes during and following treatment. III. To determine changes in nutrition status based on Global Leadership Initiative on Malnutrition (GLIM) criteria IV. To determine lean body mass before and after treatment via psoas muscle surrogate measurement on routine staging scans. V. To determine the adherence rate of Kate Farms oral nutritional replacement. VI. To determine changes in oral and gastrointestinal microbiota via 16s ribosomal ribonucleic acid (RNA) sequencing during and following treatment in an exploratory analysis. VII. To determine changes in biomarkers during treatment. VIIa. Serum human papillomavirus (HPV) deoxyribonucleic (DNA). VIIb. 38-multiplex immune cytokine and chemokine panel in an exploratory analysis. VIIc. Complete metabolic panel, complete blood count with differential, C-reactive protein (CRP). VIId. Radiosensitivity germ-line biomarker panel. VIII. To determine physician-reported acute and late toxicities during and following treatment. VIIIa. Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. IX. To determine patient-reported quality of life during and following treatment. IXa. University of Washington and Functional Assessment of Cancer Therapy questionnaires. IXb. Functional Assessment of Cancer Therapy-Head \& Neck (FACT-H\&N). X. To determine clinical outcomes from treatment. Xa. Local/Locoregional control. Xb. Distant metastasis-free survival. Xc. Overall survival. OUTLINE: Patients receive Kate Farms pea protein oral nutrition supplement orally (PO) during their mealtimes as directed by their clinical dietitian during and up to 1 month following chemoradiation in the absence of unacceptable toxicity. After completion of study intervention, patients are followed up for a minimum of 2 years.
