Etelcalcetide (Parsabiv) vs Pasireotide (Signifor)

An educational, source-based comparison of Etelcalcetide (Parsabiv) and Pasireotide (Signifor) — 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.

Somatostatin Analog · Endocrine
Pasireotide (Signifor)

Multi-receptor somatostatin analog for Cushing's disease and acromegaly.

Mechanism

Cyclohexapeptide somatostatin analog binding somatostatin receptors SST1, 2, 3, and 5 (with highest affinity for SST5), suppressing ACTH in corticotroph adenomas and GH/IGF-1 in somatotroph tumors.

Research areas
  • Cushing's disease
  • Acromegaly (LAR formulation)
Considerations
  • FDA-approved.
  • Significant hyperglycemia risk requires glucose monitoring.
  • Bradycardia and QT prolongation possible.
