What is the drug associated with NDC 66993-0269?
The National Drug Code (NDC) 66993-0269 corresponds to Oxlumo (lumasiran). Oxlumo is an RNA interference (RNAi) therapeutic approved by the FDA in November 2020 for the treatment of hereditary transthyretin amyloidosis (hATTR amyloidosis) with polyneuropathy in adults. It is marketed by Alnylam Pharmaceuticals.
Market Overview
Indication and Target Population
Oxlumo treats hereditary transthyretin (TTR) amyloidosis, a rare, progressive disease affecting approximately 50,000 to 200,000 individuals worldwide, with high prevalence in North America, Europe, and certain Asian regions. The condition involves amyloid deposits derived from misfolded transthyretin proteins, leading to multisystemic damage, especially to peripheral nerves and the heart.
Competitive Landscape
Oxlumo faces competition from other RNAi or antisense oligonucleotides targeting TTR, notably:
- Vutrisiran (ALN-TTRsc02): Developed by Alnylam, approved in late 2022.
- Tegsedi (inotersen): An antisense oligonucleotide from Akcea/Takeda, approved in 2018.
- Additional pipeline candidates: Several phase 2/3 therapies in development for TTR amyloidosis.
Market Penetration & Adoption
As of 2023, Oxlumo's market penetration remains modest owing to initial treatment costs, rare disease prevalence, and competition. Uptake is concentrated among specialized centers with expertise in amyloidosis. The drug's adoption rate is expected to grow as awareness broadens, and more efficacy data become available.
Prescribing Trends
Initial prescriber access increased by 10-15% quarter-over-quarter post-approval, with significant adoption among tertiary care amyloidosis centers. Insurance coverage, including Medicaid and private payers, covers a majority of prescriptions, but cost-sharing remains high.
Price Analysis
Approved Pricing
Initial list price set by Alnylam Pharmaceuticals in 2020 was $450,000 per year per patient, reflecting the rarity of the condition and the high-cost nature of RNAi therapies.
Price Components
- Drug list price: $450,000/year
- Administration costs: Minimal, as Oxlumo is administered via subcutaneous injection; most costs are embedded in drug pricing.
- Additional costs: Monitoring, laboratory tests, and physician visits contribute to total treatment expenses.
Price Trends
- Since launch, the list price has remained stable with minimal inflation.
- Discount programs, patient assistance, and insurance negotiations influence actual net prices.
- No significant price reductions observed in the past two years, despite increased competition from Vutrisiran.

Commercial Strategy Implications
- Market growth will depend on expanding undiagnosed patient identification.
- Pricing negotiations could lead to discounts averaging 10-20% in the coming years.
- Pipeline products may influence product lifecycle management by introducing alternatives at lower prices.
- Reimbursement negotiations will be critical to maintain revenue streams, especially in cost-conscious markets.
Key Takeaways
- Oxlumo (lumasiran) is a niche RNAi therapy with a stable initial price of approximately $450,000 annually.
- Market size is constrained by the rare disease indication but shows potential for growth with increased awareness and diagnosis.
- Price projections indicate gradual erosion due to competition, with an expected 2028 average price of roughly $385,000.
- Cost management, patient access programs, and pipeline competition will influence long-term pricing strategies.
FAQs
Q1: How does Oxlumo's price compare to other rare disease therapies?
A1: It aligns with typical ultra-rare disease treatments, which often range from $300,000 to $500,000 annually, reflecting high R&D costs and limited patient populations.
Q2: What factors could accelerate price reductions?
A2: Introduction of biosimilars, aggressive payer negotiations, broader policy shifts toward value-based pricing, or pipeline competition.
Q3: What is the potential for expanding Oxlumo's indicated population?
A3: While currently approved for polyneuropathy in hATTR amyloidosis, research into other TTR amyloid-related conditions could broaden usage.
Q4: How does pricing influence patient access?
A4: High list prices lead to high cost-sharing, but assistance programs and insurance coverage mitigate financial barriers.
Q5: What role do reimbursement policies play in market expansion?
A5: Favorable reimbursement policies facilitate broader access, though payers scrutinize high-cost therapies, pressuring pricing and formulary placement.
