VOXZOGO
vosoritide · INN
MoACNP analog (FGFR3 antagonism)

VOXZOGO (vosoritide) is a once-daily subcutaneous injection developed by BioMarin for achondroplasia — the most common form of short-limb dwarfism, caused by a gain-of-function FGFR3 mutation that suppresses bone growth at the growth plates. The drug is a synthetic analog of C-type natriuretic peptide (CNP), a signaling molecule that inhibits the overactive FGFR3 receptor, allowing growth plates to develop more normally and increasing annualized height velocity in children. VOXZOGO is approved in the US for patients aged 5 and older; BioMarin is pursuing a label extension for infants from age 4 months.
