Clinical Trial Summary

X-linked hypophosphatemia (XLH) is the most common form of heritable rickets. Current treatments include active vitamin D metabolites (e.g. calcitriol) and phosphate salts. There is no consistent weight-based dosing of calcitriol and phosphate now. The primary objective of this study is to establish the efficacy of different dose of calcitriol combined with neutral phosphate in children with XLH.
