Prebiotic Food-Enriched Diet to Enhance the Microbiome and Response to First-Line Immunotherapy in Patients with Stage III or IV Unresectable Cutaneous, Uveal, Acral or Mucosal Melanoma

Trial Status: active

This clinical trial studies the possible effects of a prebiotic food-enriched diet (PreFED) targeting the gut microbiome in patients with stage III-IV cutaneous, uveal, acral or mucosal melanoma that cannot be removed by surgery (unresectable) who are starting immune checkpoint inhibitor (ICI) therapy. The gut microbiome is the collection of microorganisms (like bacteria or fungi) that are present in the digestive system. PreFED is a diet intervention focused on behavior change and has some provision of whole foods (with no dietary supplements). Prebiotic foods, high in dietary fiber and other key nutrients, selectively support beneficial gut microbes that maintain the health of the overall gut ecosystem. Giving a PreFED in combination with standard of care ICI may help improve the gut microbiome and general health of patients with stage III or IV unresectable cutaneous, uveal, acral or mucosal melanoma.
