Vitamin D Loading Dose in Advanced Lung Cancer
Open Clinical Trial to Validate a Short-term Vitamin D Loading and Maintenance Dose Protocol in People With Advanced Lung Cancer
Hypovitaminosis D is highly prevalent in people with lung cancer, and may have adverse clinical consequences. The long and variable pharmacokinetic half-life of vitamin D makes prompt vitamin D replacement problematic. This is an open, one-armed therapeutic intervention using a loading dose of vitamin D that will be predicted to increase plasma 25-hydroxyvitamin D concentrations of every patient well into the normal range (> 100 nmol/L) within 2 or 3 weeks and monitored after 2 and 3 weeks of loading and maintenance dose. Preliminary data will also be obtained to identify potentially clinical important outcome benefits for future investigation. The outcomes are
- plasma 25OHD concentration
- Vitamin D binding protein and other plasma concentrations
- Mood and symptom
