What Is the Drug NDC 62559-0220?
NDC 62559-0220 corresponds to Givlaari (givosiran), a prescription drug approved by the FDA in November 2019. Givlaari manages acute hepatic porphyria (AHP), a rare metabolic disorder affecting heme biosynthesis. It received orphan drug designation, giving it exclusivity until 2026 in the U.S.
Market Size and Patient Population
Prevalence of AHP: Estimated at 1,500 to 3,000 patients in the U.S., with about 100 to 200 new cases annually. Givlaari is prescribed for adults with confirmed AHP.
Market penetration: Givlaari has been adopted primarily in specialty centers. The drug's lifetime addressable market remains constrained by rarity.
Pricing and Revenue Data
List Price: The wholesale acquisition cost (WAC) is approximately $34,150 per 28-day treatment cycle (as of 2023).
Net Price: Actual net prices depend on negotiated discounts, rebates, and patient assistance programs, typically reducing list price by 20–30%.
Annual Revenue Estimates: Industry analysts project U.S. revenue between $300 million and $500 million in 2023, with some growth potential driven by increased adoption and expanded indications.

Market Competitors
- Panhematin (hemin for injection): Approved since 1985 for acute attacks. Limited efficacy data and administration complexity restrict its use.
- Foscarbil (Gencor): Investigational agent in clinical trials, with no commercialization as of 2023.
- Emerging therapies: RNA interference drugs targeting the same pathway, such as Hepzora (Hepzora is not directly targeted at AHP, utilized in other hepatic diseases, but serves as an example of drug development in hepatic metabolism.)
Price Projection Factors
- Market Penetration: Givlaari's adoption rate depends on sales channels and physician familiarity. Slow initial uptake can be offset by gradual market expansion.
- Pricing Trends: Orphan drugs tend to maintain high prices due to limited competition, though pricing pressures from payers and legislation exist.
- Reimbursement Outcomes: Payment models are evolving toward value-based agreements, which could influence net revenue.
- Regulatory Changes: Orphan drug regulations protect exclusivity until 2026 in the U.S., after which biosimilars or generics could emerge.

Risks and Opportunities
Risks: Entry of biosimilars post-2026, payer push for price reductions, slow market adoption, and alternative treatments gaining approval.
Opportunities: Expanded indications, real-world evidence demonstrating improved outcomes, and international market penetration.
Summary
Givlaari (NDC 62559-0220) has a high-priced, limited patient market, with projected revenues around $350–$500 million annually in the U.S. through 2026. Price stability depends on payer negotiations, regulatory protections, and clinical development trajectory.

FAQs
Q1: How does Givlaari compare price-wise to other orphan drugs?
It is on the higher end, comparable to drugs like Lumryza (~$350,000 per year) and Soliris (~$500,000 per year), due to its specialty status and limited patient base.
Q2: What factors could reduce Givlaari’s future revenue?
Introduction of biosimilars post-2026, tighter payer controls, and slow adoption could diminish revenue streams.
Q3: Are there approved generic or biosimilar versions of Givlaari?
No, as of 2023, no biosimilars or generics have received approval, protected by orphan drug exclusivity until 2026.
Q4: Could Givlaari's pricing change significantly before patent expiry?
Pricing stability is likely until biosimilars or competitors enter the market, with some downward pressure possible due to payer negotiations.
Q5: Are international markets significant for Givlaari?
International demand is emerging but remains limited by disease prevalence, healthcare infrastructure, and regulatory approval status.
