What this is

  • Etelcalcetide is a peptide calcimimetic: it activates the calcium-sensing receptor to reduce parathyroid-hormone secretion.

What this isn't

Key terms

Etelcalcetide is a peptide calcimimetic: it activates the calcium-sensing receptor to reduce parathyroid-hormone secretion.

In advanced kidney disease, disturbed mineral balance can drive persistently high parathyroid hormone. Etelcalcetide activates the parathyroid calcium-sensing receptor, reducing hormone release and often lowering blood calcium. It therefore addresses a dialysis-associated endocrine disorder, not calcium deficiency or a general need to strengthen bones. PARSABIV pharmacology and indication.

Evidence limits

How to read the evidence

A lower PTH value does not demonstrate fewer fractures, fewer cardiovascular events, or longer survival. The label does not recommend extrapolation to primary hyperparathyroidism, parathyroid carcinoma, or kidney disease without hemodialysis. Comparing laboratory response with cinacalcet also does not resolve the balance of symptoms, monitoring burden, and long-term outcomes for an individual patient. Label boundaries; trial conclusion.
