A Dietary Study for People With Multiple Myeloma

The purpose of the study is to find out whether a dietary intervention can affect treatment response and/or quality of life for people with newly diagnosed multiple myeloma receiving standard induction chemotherapy with daratumumab (or isatuximab), lenalidomide, bortezomib, and dexamethasone (DRVd). The researchers will measure quality of life by having participants complete questionnaires. The study will investigate the effects of diet on quality of life, treatment response, and other disease, microbiome, and immune markers.
