Market Drivers
- Increasing diagnosis rates: Advances in diagnostics have improved detection, expanding eligible patient pools.
- Pediatric approval: Extends market access to children, accounting for ~15% of patients.
- Biologic advancements: Development of biosimilars and alternative formulations pressure pricing.
- Regulatory incentives: Orphan drug designation accelerates approvals and extends exclusivity (up to 7 years in the US).
Market Constraints
- High therapy costs: Limiting affordability in emerging markets.
- Limited patient population: Gaucher disease's rarity (~1 in 50,000 worldwide) constrains sales volume.
- Competition from gene therapies: Emerging treatments like Pfizer's Intensify (elivaldogene autotemcel) could pose future threats.
