Study Details

The purpose of this study is to better understand how X-linked hypophosphatemia (XLH) affects the body and daily life. Phosphate levels are critical in managing XLH, we aim to study how these levels change in patients taking burosumab and how they relate to bone health, overall disease burden and XLH-related conditions.
