Burosumab Sales Market Forecast
"Key Factors Driving Burosumab Growth
1. Market Share Gains and New Patient Starts
• Burosumab (CRYSVITA), developed by Kyowa Kirin and commercialized with Ultragenyx, is the first targeted therapy for X-linked hypophosphatemia (XLH) and has rapidly become the standard of care, displacing conventional phosphate and vitamin D regimens.
• Steady growth in new patient starts is being driven by earlier diagnosis, pediatric-to-adult treatment continuation, and strong physician confidence in its disease-modifying mechanism.
• Structured patient support programs and strong engagement with metabolic bone disease specialists have accelerated adoption across pediatric and adult treatment centers.
2. Expansion Across Key Indications
• X-linked Hypophosphatemia (XLH): Burosumab is widely used in both pediatric and adult XLH patients, improving phosphate homeostasis, bone mineralization, and physical function.
• Tumor-Induced Osteomalacia (TIO): The drug is also approved for adults with TIO, broadening its addressable patient base beyond inherited disease.
• Ongoing research continues to explore long-term outcomes, functional benefits, and quality-of-life improvements, reinforcing its role as a foundational therapy in FGF23-mediated disorders.
3. Geographic Expansion
• Burosumab is now approved and marketed across North America, Europe, Japan, and several Asia-Pacific countries, with continued rollout in emerging markets.
• The Asia-Pacific region is expected to show strong growth due to improved rare-disease diagnostics, national reimbursement programs, and higher awareness of metabolic bone disorders.
• Strategic partnerships between Kyowa Kirin and Ultragenyx continue to expand access through regional distribution and patient access agreements.
4. New Indication Approvals
• Regulatory agencies have expanded Burosumab’s label from pediatric XLH to include adult XLH and tumor-induced osteomalacia, significantly broadening its clinical utility.
• These approvals enhance its competitive position and allow treatment across the full disease spectrum, from childhood through adulthood.
5. Strong Volume Momentum
• XLH remains the primary growth driver, with high treatment persistence as patients transition from pediatric to adult care.
• Prescription volumes continue to rise as more patients are identified through genetic screening and specialist referral networks.
• Real-world evidence demonstrates sustained biochemical correction and functional improvements, supporting long-term treatment adoption.
6. Competitive Differentiation and Market Trends
• Burosumab is a monoclonal antibody against FGF23, directly targeting the root cause of phosphate wasting rather than providing symptomatic supplementation.
• Its biologic, disease-modifying profile differentiates it from legacy oral phosphate therapies, improving adherence and safety.
• Broader trends toward precision medicine, rare disease screening, and value-based reimbursement strongly favor Burosumab’s long-term positioning.
• Growing use of real-world evidence (RWE) continues to strengthen payer and prescriber confidence.
Burosumab Recent Developments
• Label expansions in major markets now cover both pediatric and adult XLH as well as TIO, reinforcing Burosumab’s leadership in phosphate-wasting disorders.
• Long-term real-world and extension trial data presented at international endocrinology and bone conferences continue to confirm durable efficacy and safety beyond five years of treatment.
• Kyowa Kirin and Ultragenyx have expanded reimbursement agreements in Europe and Asia, improving patient access in publicly funded healthcare systems.

Burosumab Drug Summary
Burosumab (CRYSVITA) is a fully human IgG1 monoclonal antibody that binds to and inhibits fibroblast growth factor 23 (FGF23), a phosphaturic hormone elevated in X-linked hypophosphatemia (XLH) due to PHEX gene mutations, thereby restoring renal phosphate reabsorption (increasing TmP/GFR), elevating serum 1,25-dihydroxyvitamin D levels to enhance intestinal phosphate and calcium absorption, and supporting bone mineralization to heal rickets/osteomalacia in children and adults with XLH. Administered subcutaneously every 4 weeks (e.g., 0.8 mg/kg up to 1.2 mg/kg max based on serum phosphorus, not exceeding 90 mg or 180 mg per dose), it significantly improves serum phosphorus, radiographic rickets severity (RSS score), growth velocity, and pain/walking ability as shown in Phase II/III trials (UX023-CL301, CL303), outperforming conventional phosphate/vitamin D therapy with a favorable safety profile though requiring monitoring for hyperphosphatemia and hypersensitivity.
