US approval for first-ever inherited rickets therapy

The FDA have approved Ultragenyx and Kyowa’s Crysvita, a treatment for x-linked hypophosphatemia (XLH) in both adults and children. The disease is an inherited form of rickets which causes low levels of phosphorous in the blood which leads to impaired bone growth and development as well as bone mineralisation problems throughout the patient’s lifetime. The treatment is an antibody that blocks the fibroblast growth factor 23 (FGF23) leading to decreased phosphate urinary excretions and increased active vitamin D production. Its dosing regimen is also believed far less burdensome than other current therapies. If you would like to read more, please click here for a PharmaTimes article.
