VOXZOGO®, a C-type natriuretic peptide analogue, is the only pharmacological treatment available in Canada that has been demonstrated to improve body proportionality and increase growth velocity versus placebo in patients with achondroplasia.1,3
The treatment, first approved by the U.S. Food and Drug Administration (FDA) in 2021 and later by the European Medicines Agency (EMA)2, acts at the level of the intracellular signaling pathway downstream of the fibroblast growth factor receptor 3 (FGFR3) gene mutation, promoting endochondral ossification.1
"The approval of VOXZOGO in Canada marks a transformative moment for children and families living with achondroplasia. For the first time, we have a therapy that directly targets the underlying biology of the condition. This represents not only scientific progress, but real hope for families that have waited decades for new options," said Dr. Peter Kannu, Paediatrician and Clinical Geneticist, University of Alberta.
Marie-Josee Toutounji, Medical Director, Canada, at BioMarin said "Health Canada's authorization of VOXZOGO is a significant milestone for the achondroplasia community in Canada, and another step forward in BioMarin's commitment to increase access to this therapy for patients and their families."
Safety Summary
The results of the 111-301 study showed that VOXZOGO® was well tolerated. The most common adverse event related to its use was injection site reaction. The majority of events in the Phase 2 or 3 clinical studies were mild or moderate in severity.1,3
