Objectives: Achondroplasia (ACH), caused by a mutation in the fibroblast growth factor receptor 3 gene (FGFR3), leads to inhibition of endochondral bone growth. Vosoritide is a biological analogue of C-type natriuretic peptide (CNP), a potent stimulator of endochondral bone growth. A Phase 2, open-label, sequential cohort, dose-escalation study was conducted to evaluate the safety, tolerability, and efficacy of vosoritide for 24 months in children with ACH aged 5&#150...

Introduction: Vosoritide increases growth in children with achondroplasia aged 5–18 years (Savarirayan et al, Genet Med, 2021). We recently reported results from a phase 2, randomized, double-blind, placebo-controlled study (111-206) in young children with achondroplasia aged 3 months–5 years Here we present results from an open-label extension study (111-208) spanning up to 4 years of treatment in the children aged 2-5 years at study star...
