Cholecalciferol in Newly Diagnosed Non-Hodgkin Lymphoma or Chronic Lymphocytic Leukemia With Vitamin D Deficiency
A Pilot Study of Vitamin D Replacement in Patients With Non-Hodgkin's Lymphoma or Chronic Lymphocytic Leukemia With Low Vitamin D Levels
Source: ClinicalTrials.gov · Last updated 21 Apr 2026
Brief summary (registry, in English)
This randomized pilot early phase I trial studies how well cholecalciferol works in treating patients with newly diagnosed non-Hodgkin lymphoma or chronic lymphocytic leukemia with low levels of vitamin D (vitamin D deficiency). Cholecalciferol may increase levels of vitamin D and improve survival in patients with non-Hodgkin lymphoma or chronic lymphocytic leukemia receiving standard of care chemotherapy.
