Biochem/physiol Actions

Doxercalciferol is a Vitamin D2 analogue, a Vitamin D Receptor Activator (VDRA). Doxercalciferol acts as a pro-hormone, needing 25-hydroxylation in the liver for bioactivation into 1α, 25-hydroxyvitamin D2. Pivotal studies in adults on dialysis have demonstrated control of secondary hyperparathyroidism that is superior to placebo therapy, without undue suppression of 1st IMA-PTH < 300 pg/mL, or occurrences of hypercalcemia. Doxercalciferol has been shown to be effective in controlling secondary hyperparathyroidism of adult patients with CKD stages 3-4.
Doxercalciferol is a vitamin D2 analog that acts as a pro-hormone, activated in the liver to 1α,25-dihydroxyvitamin D2. Despite its relatively low affinity for the vitamin D receptor (VDR) (before activation), it is effective at suppressing expression of the parathyroid hormone (PTH) gene, and appears to act through the VDR.

Docetaxel is standard of care for androgen-independent prostate cancer (AIPC). Doxercalciferol (1 alpha-hydroxyvitamin D2) had modest activity in phase I/II trials. Preclinical data support combining vitamin D analogues with docetaxel to treat AIPC. Chemotherapy-naive men with metastatic AIPC were randomized
