Overview
The drug identified by NDC 42291-0347 corresponds to Lumasiran (Oxalosis and Primary Hyperoxaluria Type 1). It is marketed under the brand name Oxlumo, developed by Alnylam Pharmaceuticals. Approved by the FDA in November 2020, Lumasiran is the first RNA interference therapy targeting primary hyperoxaluria type 1 (PH1).
Market Landscape
Target Population
- PH1 is a rare genetic disorder characterized by overproduction of oxalate leading to kidney stones and progressive kidney damage.
- Prevalence estimates suggest approximately 1 in 1 million to 1 in 200,000 individuals in the U.S. are affected.
- Estimated total U.S. patient pool: approximately 300-400 patients.
Competitive Environment
- Primary competitors include older treatments like dialysis, kidney transplants, and supportive therapies.
- No direct RNAi competitors currently approved.
- Off-label use of metabolic disorder medications is limited.
Market Drivers
- Increasing awareness of PH1.
- Growing adoption of genetic therapies.
- Significant unmet medical needs among the patient population.
- Payer acceptance following FDA approval, driven by the drug’s targeted mechanism.
Regulatory and Reimbursement Factors
- FDA approval granted based on Phase 3 clinical trial outcomes showing significant reduction in urinary oxalate.
- Insurance coverage is evolving, with payers increasingly favoring targeted therapies for rare diseases, leading to premium pricing strategies.

FAQs
What is the main competitive advantage of Lumasiran?
It is the first FDA-approved RNA interference therapy specifically for PH1, offering targeted treatment with significant reductions in urinary oxalate.
How does the price of Oxlumo compare to other rare disease treatments?
It is comparable or slightly higher than similar gene therapies, often exceeding $400,000 annually due to the high cost of development and small patient populations.
Are biosimilars or generics expected for Lumasiran?
No biosimilars are in development currently; biosimilar entry is unlikely before 2028 given regulatory and development timelines.
What factors could influence future pricing?
Increased payer pressure, expanded indications, or biosimilar competition could lead to price reductions or rebates.
What is the estimated market size for this drug?
Approximately 300-400 patients in the U.S., translating to a potential annual revenue of around $135 million to $180 million at current prices.
