A complete explanation of the applicable populations and clinical applications of vosoritide

Vosoritide (vosoritide) is a recombinant human C-type natriuretic peptide-derived peptide, mainly used to treat pediatric patients with osteogenic dysplasia achondroplasia (achondroplasia). Its mechanism of action is to selectively activate the C-type natriuretic peptide receptor (NPR‑B) in osteoblasts and chondrocytes, promoting cell proliferation and differentiation of the cartilage plate, thereby improving bone growth and increasing height growth. Vorsolitide is the first targeted therapy approved for this specific genetic form of short stature, providing a new treatment option for children with the disease.

Clinical trial data show that vorsolitide can significantly increase the annual growth rate of children. In children aged 5 to 14 years old, daily subcutaneous injection of versolitide 15 μg /kg body weight increased the height growth rate by approximately 1 compared with the untreated group. to 2 cm / years, and maintain the therapeutic effect. Long-term follow-up shows that the drug can still maintain the synchronization of bone age progression and height growth after continuous use for 2 years. At the same time, no serious bone development abnormalities or adverse effects on major organs have occurred, providing stable long-term treatment benefits for children.

The applicable population is mainly children diagnosed with achondroplasia, especially school-age children or early adolescents aged 2 to 14 years old. Before treatment, genetic or clinical diagnosis must be carried out to confirm that the child has a dwarf phenotype related to FGFR3 gene mutation to ensure the pertinence of targeted therapy. During use, changes in height, weight and bone age need to be monitored regularly, as well as blood pressure, electrolytes and kidney function to ensure safe medication and sustained efficacy.

In clinical application, vorsolitide can not only improve height growth, but also improve patients' quality of life and psychological state to a certain extent. While the children's height and body shape have improved, their daily activities and self-confidence have also improved. Although the drug was generally well tolerated, common side effects included redness and swelling at the injection site, mild hypotension, and mild headache, most of which resolved spontaneously or were controlled by adjusting the injection regimen. Through standardized medication management and doctor's guidance, Vosolitide provides a practical and effective growth improvement program for children with achondroplasia.
