| Condition | X-linked hypophosphatemia (XLH) |
| Key Mechanisms | Burosumab improves phosphate metabolism and reduces rickets symptoms. |
| Target Population | Pediatric patients with symptomatic XLH and adults with pseudofractures or inadequate response to conventional therapies. |
| Care Setting | Clinical practice guidelines for diagnosis and management of XLH. |
Key Highlights

- Demonstrated a 43.1% healing rate for active fractures by week 24.
- Recommended biweekly dosing of 0.8 mg/kg for pediatric patients.
- Monitoring includes serum phosphate levels; FGF23 levels not required.
- Burosumab contraindicated during pregnancy.
Guideline-Based Recommendations
Diagnosis
- Diagnosis of XLH should consider clinical symptoms, elevated ALP, and radiologic signs of rickets.
Management
- Burosumab is recommended as primary therapy for pediatric patients with symptomatic XLH.
Monitoring & Follow-up
- Monitor serum phosphate levels during burosumab treatment.
Risks
- Burosumab is contraindicated in pregnancy due to potential reproductive toxicity.
Patient & Prescribing Data
Pediatric patients with symptomatic XLH and adults with pseudofractures or inadequate response to conventional therapies.
Burosumab improves quality of life and reduces bone pain and fatigue in pediatric patients.
