Official title
Efficacy of Vitamin D Supplementation in Vitamin D-deficient Subjects at Risk of Lung Cancer (The Pittsburgh Vitamin D Study)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
