ASH 2023 | ILyAD study: vitamin D supplementation in low tumor-burden indolent NHL treated with rituximab
Jonathan Friedberg, MD, MMSc, University of Rochester, Rochester, NY, provides an update on the ILyAD study (NCT03078855) – a double-blind, randomized trial which aimed to evaluate the effect of vitamin D (cholecalciferol) supplementation on disease outcomes in patients with low tumor-burden indolent non-Hodgkin lymphoma (NHL) treated with rituximab. There have been multiple reports of a significant association between low vitamin D levels at diagnosis and inferior overall survival. However, this study reported no statistically significant benefit of vitamin D supplementation on the outcomes of patients, suggesting that low vitamin D may be a surrogate for illness and comorbidity rather than a risk factor that can be addressed. This interview took place at the 65th ASH Annual Meeting and Exposition, held in San Diego, CA.
