High-Intensity Exercise and High-Fiber Diet for Immunotherapy Outcomes in Melanoma Patients: The DUO Trial

This single-center, four-arm, pilot randomized research study is to test if high-intensity exercise and high-fiber diet are feasible and effective in improving the gut microbiome health, immune function, physical fitness, treatment-related side effects, and treatment outcomes in participants with advanced melanoma receiving immunotherapy. Participants will be randomized into 1 of 4 study groups: Group A Exercise, Group B Diet, Group C Combined, and Group D Attention Control. Randomization means a participant will be placed into an intervention group by chance. The information learned by doing this research may help determine whether participating in such lifestyle interventions are tolerable during immunotherapy and exert health benefits among melanoma participants. The research study procedures include screening for eligibility, study visits, stool samples, blood tests, and questionnaires. Participation in this study is expected to last up to a total of 9 weeks. It is expected about 40 people will take part in this research study. This study is sponsored by the World Cancer Research Fund International and American Association for Cancer Research.
