How can VOXZOGO help my child?
VOXZOGO is indicated to increase linear growth in children with achondroplasia aged 5 years and up whose growth plates are still open. See the results in children receiving VOXZOGO in the clinical trial.
What should I know about VOXZOGO safety?
The safety profile of VOXZOGO has been studied over 1 year of treatment compared with placebo. Talk to your child’s doctor about the potential side effects.
Learn about the side effects from the clinical trial.
How does VOXZOGO work?
Achondroplasia affects endochondral bone growth—this is bone growth that replaces cartilage with bone tissue as your child grows. A balance between fibroblast growth factor receptor 3 (FGFR3) and C-type natriuretic peptide (CNP) signaling pathways occurs within the cells in the growth plate. FGFR3 slows bone growth while CNP promotes bone growth.
Achondroplasia is caused by an imbalance between FGFR3 and CNP signaling pathways and leads to impaired bone growth. Learn how VOXZOGO targets the imbalance to promote growth.
How do I get my child started with VOXZOGO?
How can I find a local doctor for my child?

A healthcare provider will train you on how to give your child VOXZOGO at home. A BioMarin Clinical Coordinator is also available for injection training support and ongoing education.
In addition, we have resources, like videos and pamphlets, to help guide you throughout treatment.
What is the age cutoff for starting my child on VOXZOGO?
VOXZOGO is indicated for increasing linear growth in children with achondroplasia aged 5 years and up with open growth plates. As long as growth plates are open, there is an opportunity for bone growth. In the clinical trial, some children who received VOXZOGO were up to 15 years old. Talk to your doctor who can determine potential for growth.
How long will my child take VOXZOGO?
VOXZOGO helps to improve annualized growth velocity in children with achondroplasia aged 5 years and older while their growth plates are open.
Regular checkups with your child’s prescribing doctor will be able to determine when their growth potential has been reached, and your child’s doctor will stop treatment when growth plates are closed. In the clinical trial, some children receiving VOXZOGO were up to 15 years old.
