CRYSVITA® demonstrates rapid and significant improvements in biochemical and clinical outcomes in children with XLH1,3*
CRYSVITA® significantly improved rickets healing and reduced severity1,3
CRYSVITA® significantly improved growth and mobility outcomes1,3
CRYSVITA® significantly improved biochemical markers of phosphate regulation and bone health1,3
*Based on a Phase 2 and a Phase 3 study. In the Phase 2 study, 52 children with XLH aged 5–12 years were randomised to receive CRYSVITA® either every 2 weeks or every 4 weeks (dose was titrated according to serum phosphorus concentration). In the Phase 3 study, 61 children with XLH aged 1–12 years were randomised to receive either CRYSVITA® (0.8 mg/kg starting dose, administered every 2 weeks) or conventional therapy (oral phosphate and Vitamin D). In both studies, change in rickets was assessed at 40 weeks.
