Study Summary
This study aims to establish the ability of 4,000 IU oral vitamin D3 per day (in combination with a daily multivitamin) to safely convert vitamin D3-deficient subjects at increased risk of lung cancer to a vitamin D3-sufficient state, and to explore effects of vitamin D3 supplementation in this population on markers of inflammation and lung cancer risk. Current and former smokers with chronic obstructive pulmonary disease (COPD) are at increased risk of developing lung cancer and represent the clinical population of interest for this study.
Primary Outcome
The proportion of subjects whose baseline vitamin D3 deficiency is corrected after 12 months of supplementation (i.e., the 12-month conversion rate).
Interventions
