Etelcalcetide is a drug used to treat secondary hyperparathyroidism , a disease that occurs mainly in people with chronic kidney disease and leads to elevated levels of parathyroid hormone .
Drug structure and pharmacokinetics
Etelcalcetide consists of a peptide of seven D - amino acids that form the basic structure of the molecule in a linear chain. A D - cysteine is linked to an L - cysteine via a disulfide group:
Ac-DCys-DAla-DArg-DArg-DArg-DAla-DArg-NH2 | H-LCys-OH
The molecular weight of the active ingredient is 1048.3 Da . The drug is metabolized through disulfide exchange with thiol-containing molecules in the body and takes place less through enzymes . Laboratory tests did not show any effect on the important cytochrome P450 metabolism. In human blood, the drug binds covalently to the blood protein albumin via a disulfide bond . The drug is excreted through the kidneys and, in dialysis patients, removed from the blood by hemodialysis.
Drug effect
Etelcalcetide is an allosteric modulator of the calcium- sensitive receptor on the parathyroid gland. Like other drugs in its class of active ingredients, the drug increases the sensitivity of the receptor by binding, which in turn reduces the downstream parathyroid hormone production. The administration of the drug is intravenous. Two randomized and controlled prospective studies were able to demonstrate a comparable effect with the orally administered drug Cinacalcet .
Admission status
- European Union : On November 11, 2016, etelcalcetide was approved for the treatment of secondary hyperparathyroidism in adult patients with chronic kidney disease undergoing hemodialysis therapy.
- USA: The American FDA approved etelcalcetide on February 7, 2017.
