NCT02022475

Brief Summary

Primary objective

  • Change in Fatigue Assesment Score (FAS) between the first visit (baseline) and 28 (+maximum 7) days after oral administration of 100 000 E vitamin D (Cholecalciferol). Secondary objectives
  • Effect of oral administration of vitamin D on serum vitamin D levels (25-Hydroxy-Vitamin D = Colecalciferol), PTH, Calcium, and Phosphate as compared to placebo.
  • Efficacy of vitamin D (Colecalciferol) administration on fatigue using the short self-developed FCA-Test
  • Safety of 100 000 E oral vitamin D (Colecalciferol) administration as compared to oral placebo. Laboratoty parameters such as serum calzium and phosphate levels and the number of adverse events compared to placebo will be used for safety monitoring.
  • Efficacy of oral administration of vitamin D (Cholecalciferol) on plasma FGF-23, Sclerostin and Klotho levels compared to placebo.
