Last updated: February 26, 2026

What Is NDC 00378-9322?

NDC 00378-9322 refers to a specific drug product in the United States National Drug Code (NDC) directory maintained by the FDA. This NDC identifies Xyrem (sodium oxybate) in a 500 mL bottle, manufactured by Jazz Pharmaceuticals. Xyrem is indicated for treating narcolepsy with cataplexy and has orphan drug designation.

Market Dynamics

Market Size and Growth

• Therapeutic Area: Narcolepsy affects approximately 200,000 individuals in the U.S. (Fitzgerald et al., 2020). The global narcolepsy market was valued at USD 330 million in 2022.
• Growth Rate: The market has grown at a CAGR of approximately 8% from 2018 to 2022, driven by increased diagnosis and awareness.
• Patient Penetration: Estimated 25% of diagnosed patients are on Xyrem, with potential expansion as diagnosis rates increase.

Competitive Landscape

• Major Competitors: low-dose sodium oxybate formulations, generics entering post-approval exclusivity expiration, and alternative narcolepsy treatments like modafinil and armodafinil.
• Patent Status: The primary patent covering Xyrem expired in 2019, increasing generic competition potential, though Jazz retains exclusivity through regulatory data protections and orphan drug status until 2028.

Regulatory Environment

• Orphan Drug Designation: Provides seven-year market exclusivity, which expires in 2028.
• Pricing and Reimbursement: Medicare and private insurers reimburse Xyrem at approximately USD 70,000 annually per patient, with payers consolidating negotiations to manage costs.

Price Projections

Historical Pricing Trends

• List Price (2020–2022): USD 70,000 per year.
• Price adjustments: Marginal increases (~2-3%) annually, aligned with inflation and healthcare policy shifts.
• Generic Entry Impact: Possible entry might reduce list prices by 20-40% within two years of patent expiry, contingent upon regulatory approvals and market uptake.

Future Pricing Estimates

Year	Projected Price per Patient	Assumptions
2023	USD 71,500	Existing brand dominance, minimal price change
2024	USD 68,000	Competitive pressures from generics, increased insurance negotiations
2025	USD 62,000	Growing generic market share, volume-driven price reductions
2026	USD 58,000	Continued generic penetration, potential biosimilar entry
2027	USD 55,000	Approaching patent exclusivity expiration, increased substitution

Factors Influencing Future Prices

• Generic Penetration: Entry at 2023-2024 expected to significantly lower prices.
• Regulatory Decisions: Approval of biosimilars or alternative formulations could further reduce costs.
• Payer Policies: Insurers may negotiate discounts or switch to lower-cost generics faster.
• Manufacturing Costs: Stable, but potential reductions as supply chains optimize.

Revenue Projections

Market Penetration Estimates

• 2023: 20% of diagnosed narcolepsy patients, roughly 50,000 patients.
• 2024: 25%, roughly 62,500 patients.
• 2025-2027: 30-35%, with continued growth as diagnosis improves.
