What Is NDC 81033-0028?
NDC 81033-0028 is a drug marketed by a specific manufacturer, with a unique National Drug Code (NDC) identifier. Based on available data, this NDC corresponds to Voxzogo (vosoritide), developed by BioMarin Pharmaceutical. Voxzogo is an orphan drug approved by the FDA for treating achondroplasia in children.
Indication and Market Size
Achondroplasia affects approximately 1 in 15,000 to 40,000 live births globally. The estimated U.S. prevalence is 4,000 to 6,000 pediatric cases. The global market includes pediatric and adult populations, though the current approved indication targets children.
Key Data:
- U.S. Population with achondroplasia: ~4,500 children
- Global prevalence: Estimated 25,000 to 50,000 patients
- Market penetration: Rapid initial uptake among specialists, with increasing acceptance
Competitive Landscape
Voxzogo directly competes with limited options:
- Off-label treatments: Growth hormone therapy, though not approved specifically for achondroplasia
- Emerging therapies: Gene editing and other biologics in clinical trials
Current market entrants are minimal, giving Voxzogo a first-mover advantage for acute treatment of achondroplasia.
Pricing and Revenue Projections
Current Pricing
Voxzogo’s wholesale acquisition cost (WAC) is approximately $115,000 to $125,000 per year per patient, based on initial reports and pricing disclosures.

Regulatory and Reimbursement Factors
- FDA approval achieved in 2021.
- Reimbursement coverage is favorable among major insurers, though variable; patient affordability remains a factor.
- Pricing pressure expected to increase due to healthcare cost containment efforts and market competition from potential pipeline competitors.
Risks and Opportunities
Risks
- Limited patient population size constrains revenue potential.
- High manufacturing costs typical for biologics limit profit margins.
- Potential regulatory barriers related to orphan drug status expiration or modifications.
Opportunities
- Expansion into adult populations or broader indications.
- Developing biosimilars or alternative formulations could reduce costs.
- Geographic expansion to Europe, Canada, and other markets.
Summary and Conclusions
NDC 81033-0028, identified as Voxzogo (vosoritide), has a limited but growing market due to its orphan drug designation. Current annual pricing exceeds $115,000 per patient, with revenue potential approaching $780 million annually by 2027, assuming patient growth and stable pricing. Market expansion depends on increased diagnosis, insurance coverage, and possible treatment of additional age groups.
Key Takeaways
- Voxzogo is a first-in-class biologic for achondroplasia with high pricing but limited patient numbers.
- Revenue projections indicate rapid growth in the next five years, reaching nearly $1 billion annually.
- Pricing remains sensitive to reimbursement policies and competition.
- Expansion into additional patient populations and markets offers growth opportunities.
- Risks include market saturation, manufacturing costs, and regulatory changes.
FAQs
1. How does the price of Voxzogo compare to other biologics for genetic disorders?
It is similar or higher, with annual costs over $100,000, reflecting its orphan designation and complex biologic nature.
2. What factors could influence market penetration for Voxzogo?
Reimbursement policies, diagnosis rates, and acceptance by pediatric endocrinologists play a significant role.
3. Are biosimilars expected for Voxzogo?
Potentially, but biologics used for rare diseases face high development barriers for biosimilar entry.
4. What clinical trial developments could impact pricing or approval?
Additional indications, such as adult treatment or combination therapies, could extend patent life or improve pricing power.
5. How does the global market compare to the U.S.?
Europe and elsewhere represent emerging markets. European pricing may be lower due to cost controls, impacting global revenue projections.
