Etelcalcetide (Parsabiv) vs Vosoritide (Voxzogo)

An educational, source-based comparison of Etelcalcetide (Parsabiv) and Vosoritide (Voxzogo) — how each peptide works, what it's researched for, and what to know before going deeper.

Calcium-Sensing Receptor Agonist · Endocrine
Etelcalcetide (Parsabiv)

Calcimimetic peptide for secondary hyperparathyroidism on hemodialysis.

Mechanism

Synthetic D-amino-acid peptide that binds the calcium-sensing receptor on parathyroid chief cells, increasing its sensitivity to extracellular calcium and lowering PTH secretion.

Research areas
  • Secondary hyperparathyroidism in adults on chronic hemodialysis
Considerations
  • FDA-approved.
  • Hypocalcemia common; monitor calcium and avoid in low corrected calcium.

CNP Analog · Skeletal Growth
Vosoritide (Voxzogo)

C-type natriuretic peptide analog for achondroplasia.

Mechanism

Modified C-type natriuretic peptide (CNP) analog that binds NPR-B, antagonizing overactive FGFR3 signaling in the growth plate to increase endochondral bone growth in children with achondroplasia.

Research areas
  • Achondroplasia in children ≥5 years (now ≥4 months)
Considerations
  • FDA-approved.
  • Transient blood pressure decrease; ensure adequate hydration/food before dosing.
