Ascendis Pharma’s TransCon CNP, a once-weekly treatment for achondroplasia, demonstrated superior annualized growth velocity compared to placebo in a recent trial. This could pose a significant challenge to BioMarin’s Voxzogo, the current leading treatment for achondroplasia. While BioMarin holds a first-mover advantage, the potential for TransCon CNP’s improved dosing schedule and safety profile could impact Voxzogo’s market share in the coming years.
