 Etelcalcetide hydrochloride is the first intravenous calcimimetics agent for secondary hyperparathyroidism (SHPT). Etelcalcetide hydrochloride is to be administered through dialysis circuit by physician or medical staff upon completion of dialysis and such administration is expected to reduce the burden of medication in patients. From the nonclinical study results, etelcalcetide functions as an allosteric activator of calcium-sensing receptor(CaSR). Etelcalcetide suppressed PTH secretion both in vitro and in vivo. In a rat model of chronic renal insufficiency, etelcalcetide suppressed SHPT disorders, such as parathyroid gland hypertrophy, bone disorder, and ectopic calcification. In conclusion, etelcalcetide hydrochloride is expected to exhibit therapeutic effect against each SHPT condition by decreasing blood PTH concentrations via CaSR-agonist activity in the clinical situation.
