BioMarin Expanded Indication for Voxzogo
FDA has approved a BioMarin Pharmaceutical supplemental NDA for Voxzogo (vosoritide) to increase linear growth in pediatric patients with achondroplasia with open epiphyses (growth plates). The company says the indication was approved under accelerated approval based on an improvement in annualized growth velocity. Previously, the drug was indicated for children who were five years of age and older, and the expanded indication now includes children of all ages.
Approval was based on data from a Phase 2 clinical trial evaluating the safety and efficacy of Voxzogo in children aged five years and under. “Based on the results of this trial, together with evidence from the adequate and well-controlled Phase 3 study in pediatric patients aged five years and older (Study 111-301), safety and effectiveness of Voxzogo have been established in pediatric patients of all ages for the improvement in linear growth in children with achondroplasia with open epiphyses,” BioMarin says. The drug’s overall safety profile in children under five years of age was similar to that seen in older children, it adds.
Achondroplasia is the most common form of skeletal dysplasia leading to disproportionate short stature in humans, according to BioMarin. It is characterized by slowing of endochondral ossification, which causes “disproportionate short stature and disordered architecture in the long bones, spine, face, and base of the skull,” it says.
