Purpose: In X-linked hypophosphatemia (XLH), elevated serum FGF23 causes low serum phosphorus (Pi) and inappropriately normal 1,25-dihydroxyvitamin D (1,25(OH)2D) levels. We report safety, tolerability and biochemistry markers following single ascending dose administration of KRN23 in adults with XLH.Methods: 38 XLH subjects with baseline FGF23≥30 pg/ml were randomized to receive single doses of KRN23 (K) or placebo (P) either (0.003&#15...

Purpose: In X-linked hypophosphatemia (XLH), elevated serum FGF23 causes low serum phosphorus (Pi) and inappropriately normal 125-dihydroxyvitamin D (125(OH)2D) levels. We report PK and PD of KRN23 following single ascending dose administration in adults with XLH.Methods: 38 XLH patients with baseline FGF23≥30 pg/ml were randomized to receive a single dose of KRN23 (K) or placebo (P) either i.v. (0.003–0.3 mg/kg) or s.c. (0.1–1...
