In Brief

A clinical study evaluating Cholecalciferol and Laboratory Biomarker Analysis for Chronic Lymphocytic Leukemia and 3 related conditions. Completed, enrolled 197 participants across 1 site.

Detailed Summary

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).
