What is NDC 64950-0344?
NDC 64950-0344 is the unique National Drug Code associated with a specific pharmaceutical product. According to the FDA, this code corresponds to Ravicti (glycerol phenylbutyrate), indicated for the management of inborn errors of urea cycle disorders (UCDs). Ravicti is marketed exclusively by UreaCycle Disorders Consortium.
Market Size and Demand Drivers
Patient Population
- Urea cycle disorder prevalence: approximately 1 in 30,000 live births in the U.S.
- Estimated patients: around 400-500 in the U.S., with global figures reaching approximately 2,000.
Revenue Generation
- Urea cycle disorder management: chronic, requiring long-term therapy.
- Average annual treatment cost per patient: approximately $250,000, with variations based on insurance coverage, dosing, and region.
Market Dynamics
- Growth driven by increased diagnosis rates through expanded newborn screening programs.
- Limited competition: Ravicti is the only FDA-approved oral therapy specifically for UCD within its class, with limited marketed alternatives.

- Monthly treatment cost per patient: approximately $20,000.
- Revenue estimates projected for 2023: ~$125 million in the U.S., based on demand and pricing.
Price Projections
Short-Term (Next 1–2 Years)
- Stable pricing expected due to limited market competition.
- Potential rebates and discounts: approximately 10-15%, common in specialty pharma.
- Price pressure unlikely from generic competition; biologics and gene therapies not yet developed for UCD.
Medium to Long-Term (3–5 Years)
- No significant price drops anticipated if demand remains steady.
- Emergence of gene therapy products for UCD could disrupt pricing and market share.
- Voluntary price increases may align with inflation and R&D investments, approximately 3-5% annually.
Regulatory and Policy Impact
- Price controls or negotiations with payers: minimal current influence but may increase, particularly in cost-conscious healthcare systems.
- Rebate programs and value-based pricing models: prevalent in specialty drugs, may modulate net prices.
Market Risks and Opportunities
Risks
- Development of gene therapies or alternative treatments could reduce Ravicti's market share.
- Reimbursement policy changes could constrain pricing power.
- Competition from off-label use of other nitrogen scavengers.
Opportunities
- Growing diagnosis rate increases total revenue.
- Expansion into emerging markets with increasing healthcare coverage.
- Potential label expansion for related indications.
