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

  1. plasma 25OHD concentration
  2. Vitamin D binding protein and other plasma concentrations
  3. Mood and symptom

Condition Intervention Phase
Lung Cancer
Dietary Supplement: vitamin D

Further study details as provided by Jewish General Hospital:

Primary Outcome Measures:
  • Plasma 25-hydroxyvitamin D concentration [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
    Plasma 25OHD concentration measured within 24 h prior to commencing vitamin D therapy, and again after 14 and 21 days of continuous vitamin D therapy

Secondary Outcome Measures:
  • Mood [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]

    Two validated brief mood assessment questionnaires measured

    1. On two occasions (one week apart) at baseline prior to staring therapy
    2. After 2 weeks of therapy
    3. After 3 weeks of therapy

  • Symptoms [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
    As with mood questionnaire, a symptom questionnaire (Edmonton Symptom Assessment System) will be administered two times (one week apart) prior to starting vitamin therapy and after 14 and 21 days of continuous vitamin D administration
