Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To compare the effects on the increase of circulating levels of 25(OH)D3 of three different therapeutic regimens of Calcidiol (Didrogyl);Secondary Objective: To compare the effects of three different therapeutic regimens of Calcidiol (Didrogyl) on changes of serum and the urinary levels of mineral and bone biomarkers compared to baseline.;Primary end point(s): Efficacy: Circulating values of 25(OH)D3 at 3 months of treatment;Timepoint(s) of evaluation of this end point: 3 months | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Efficacy Serum calcium, phosphorus, creatinine, protein/albumin, ionized calcium, bone Alkaline Phosphatase (BAP), C-terminal telopeptides of type I collagen (CTX), Parathyroid Hormone (PTH), 1,25(OH)2D3, Fibroblast Growth Factor 23 (FGF 23), and vitamin D Binding Protein (D-BP) over 3 months of treatment Urinary (24 hr) calcium, phosphorus, creatinine, and deoxypyridinoline (DPD) over 3 months of treatment Safety: - Incidence of AEs - Laboratory parameters - Laboratory parameters of particular interest : calcemia, protein/albumin, ionized calcium,. CTX and 25(OH)D3 and 24 hr urinary calcium, creatinine, and D-PD ;Timepoint(s) of evaluation of this end point: 3 months | — |
