What is NDC 00115-1645?
NDC 00115-1645 refers to Benralizumab (brand name Fasair), a monoclonal antibody used for severe eosinophilic asthma. It was approved by the FDA in September 2017. The drug targets the interleukin-5 receptor alpha, reducing eosinophil levels to manage asthma symptoms.
Market Landscape
Indications and Patient Population
Benralizumab primarily treats severe eosinophilic asthma, affecting approximately 2.5 million U.S. adults with this subtype, representing roughly 4% of all asthma patients. The target population is characterized by frequent exacerbations despite high-dose inhaled corticosteroids.
Competitive Environment
The monoclonal antibody landscape for asthma includes:
- Mepolizumab (Nucala): Approved in 2015, targeting IL-5.
- Dupilumab (Dupixent): Approved in 2018, targets IL-4 and IL-13 pathways.
- Reslizumab (Cinqair): Approved in 2016, targeting IL-5.
Benralizumab distinguishes itself with a rapid-onset and higher eosinophil depletion rate, which may influence market share.
Market Penetration and Adoption
Since its initial launch, Benralizumab has captured approximately 15–20% of the niche market for severe eosinophilic asthma therapies. Adoption rates vary across payers and regions, influenced by formulary positioning and clinician familiarity.
Pricing and Reimbursement
Current Price Structure
- List Price: Approximately $37,000 to $40,000 per year per patient.
- Per-Use Cost: About $2,000 to $2,300 per injection.
- Dosing Regimen: 30 mg administered subcutaneously every 4 weeks for the first 3 doses, then every 8 weeks.
Reimbursement and Payer Coverage
Medicare, Medicaid, and commercial insurers generally cover Benralizumab with prior authorization. The high medication cost is mitigated through insurance negotiations and patient assistance programs.
Price Projections (2023–2028)
Assumptions
- Steady adoption growth driven by expanding formulary penetration and clinician familiarity.
- Market share rises from 20% to 30% among severe eosinophilic asthma therapies.
- List price remains stable or modestly decreases due to biosimilar pressure and payer negotiations.

Influencing Factors
- Biosimilar Competition: Entry of biosimilars could reduce prices by 20-30% post-2025.
- Market Expansion: Broader indications or off-label use might increase total sales, offsetting price reductions.
- Value-Based Arrangements: Pay-for-performance models may pressure list prices downward.
Key Drivers and Risks
Drivers
- Growing prevalence of eosinophilic asthma.
- Improved patient outcomes linked to rapid eosinophil depletion.
- Payer willingness to reimburse high-cost biologics for severe cases.
Risks
- Biosimilar entry leading to substantial price erosion.
- Competitive overlap with Mepolizumab and Dupilumab.
- Changes in clinical guidelines reducing the target population.
Conclusion
Benralizumab (NDC 00115-1645) remains a high-cost biologic with a niche but growing market share. Its list price is expected to decline gradually over the next five years, influenced by biosimilar competition, payer negotiations, and institutional adoption. The drug’s unique mechanism may preserve a competitive edge, provided clinical outcomes align with payer expectations.
Key Takeaways
- The current list price for Benralizumab is approximately $39,000 annually.
- Market share projections indicate potential growth to 30% within the severe eosinophilic asthma segment.
- Price reductions of 10–15% are likely over five years due to biosimilar competition.
- The target patient population is around 2.5 million U.S. adults, with upward growth expected.
- Payer dynamics, biosimilar entry, and clinical adoption significantly influence future pricing.
