Key terms
Vosoritide is a C-type natriuretic-peptide analogue that acts on growth-plate signaling in achondroplasia.
Vosoritide activates natriuretic-peptide receptor B, increasing intracellular cyclic GMP and counteracting a signaling pathway downstream of overactive FGFR3. The target is the impaired cartilage-to-bone growth process in achondroplasia. It does not alter the underlying genetic variant, and its growth-plate mechanism requires remaining potential for skeletal growth. VOXZOGO prescribing information.
Evidence limits
How to read the evidence
The accelerated approval rests on growth velocity, with confirmatory clinical-benefit requirements. It does not establish prevention of every neurologic, orthopedic, or functional complication of achondroplasia. Research in hypochondroplasia is a separate evidence stream and cannot be silently added to the approved indication. The original 52-week comparison also cannot define lifelong effects or benefits after growth plates close. Regulatory limitations; trial design.
