Lunacalcipol (CTA-018 or MT-2832) is a vitamin D analog having a dual mechanism of action. It inhibits CYP24A1 and induced VDR expression. It was being developed for the treatment of clinical consequences of vitamin D insufficiency and secondary hyperparathyroidism associated with chronic kidney disease. Lunacalcipol development has been discontinued.
