Market Analysis and Price Projections for NDC: 43538-0530
Last updated: February 24, 2026
What is the drug associated with NDC 43538-0530?
The NDC 43538-0530 corresponds to Givlaari (Givosiran), a prescription medicine approved by the FDA in November 2019. It is indicated for acute hepatic porphyria (AHP) in adults. Givlaari is a gene-silencing RNA interference (RNAi) therapeutic designed to reduce the severity of attacks associated with AHP.
What is the current market size and demand?
Patient Population and Market Drivers
Estimated prevalence: Approximately 5,000 to 10,000 patients in the United States, according to the Porphyria Association.
Target population: Patients with recurrent attacks needing prophylactic treatment.
Trigger factors: Acute attacks, often precipitated by drugs, hormones, fasting, or stress.
Current Treatment Landscape
No FDA-approved treatments before Givlaari.
Off-label therapies include hospital-based hemin infusions.
Givlaari offers a targeted, outpatient therapy with quarterly dosing, which improves patient compliance.
Market Penetration
Initial uptake: Limited, due to high cost and specialized prescribing.
Prescriptions: Estimated to be approximately 2,500 to 3,500 patients in the U.S. as of 2022, based on sales data and patent filings.
Growth factors: Increased awareness, expanding diagnostic rates, and potential expansion into Europe and other territories.
Price structure analysis
Wholesale Acquisition Cost (WAC)
Initial price: Approximately $37,200 for a 2.5 mg/kg dose, administered quarterly.
Annual cost: Estimated at $118,500 per patient based on typical dosing.
Pricing model: Fixed-price, with adjustments for weight and frequency.
Price comparison with similar therapies
Hemin infusions: Cost varies but can be between $15,000 and $30,000 per attack, often requiring repeated hospital stays.
Other RNAi therapies: No direct comparables for AHP, but reflects a high-cost biologic trend similar to other gene-silencing drugs like Onpattro (patisiran).
Reimbursement landscape
Managed care typically covers Givlaari with prior authorization.
High reimbursement rates, but cost-containment pressures exist.
Pricing pressures: Payer pushback on high-cost orphan drugs.
Diagnostic underdiagnosis: Limits market size.
Competition: Emerging therapies or biosimilars could reduce prices.
Key Takeaways
The U.S. market for Givlaari is in early growth, with pediatric and broader indications under clinical development.
Current pricing at approximately $118,500 annually per patient remains a significant revenue driver.
The market size could expand by 20-50% over the next five years, contingent upon diagnosis rates and reimbursement policies.
Generic or biosimilar development could pressure prices in the longer term.
Global expansion and pipeline advancements have the potential to further grow the market.
