Fiber fix: diet study hopes to boost cancer immunotherapy
NCT ID NCT04645680
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether eating a high-fiber diet can change the gut bacteria of people with advanced melanoma who are receiving standard immunotherapy. About 50 participants will be randomly assigned to either a high-fiber or a healthy control diet for a set period. The main goal is to see how these diets affect the microbiome and immune response, not to directly treat the cancer.
