Vosoritide
AFDA ApprovedC-type natriuretic peptide analog · 39 amino acids · Brand: Voxzogo
Vosoritide is a recombinant analog of C-type natriuretic peptide (CNP) approved by the FDA for achondroplasia in children aged 5 years and older with open growth plates. It is the first and only disease-modifying therapy for the most common form of dwarfism.
Mechanism of Action
Achondroplasia is caused by a gain-of-function mutation in the FGFR3 gene, which suppresses endochondral bone growth. Vosoritide binds to natriuretic peptide receptor B (NPR-B), activating the GC-B/cGMP pathway that counteracts FGFR3 signaling. This promotes chondrocyte proliferation and differentiation at the growth plate, increasing longitudinal bone growth.
Benefits
Side Effects
- Injection site reactions (erythema, swelling, pain)
- Vomiting
- Transient decrease in blood pressure (due to natriuretic peptide vasodilation)[1]
- Headache
- Potential for disproportionate growth of limbs vs trunk (requires monitoring)
