Mechanism
A recombinant human monoclonal anti-FGF23 antibody that binds to FGF23 and inhibits its activity, leading to increased phosphate reabsorption and increased serum concentrations of phosphate and calcitriol.

Dosing
- Adult
- 0.5 mg/kg every 4 weeks (can be increased to 2 mg/kg every 2 weeks)
- Pediatric
- 1 mg/kg every 4 weeks for X-linked hypophosphatemia.
- Renal adjustment
