Etelcalcetide Hydrochloride (AMG 416 Hydrochloride) is a synthetic peptide that acts as a calcium-sensitive receptor (CaSR) activator. Etelcalcetide hydrochloride effectively reduces parathyroid hormone (PTH) concentration in patients with secondary hyperparathyroidism undergoing hemodialysis.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
