What is the Drug Associated with NDC 42799-0962?
NDC 42799-0962 corresponds to Imfinzi (durvalumab). It is an anti-PD-L1 monoclonal antibody developed by AstraZeneca, approved primarily for the treatment of non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), and certain other malignancies.
Market Overview
Global Oncology Drug Market Context
The immuno-oncology segment exceeds $120 billion annually, driven by PD-1/PD-L1 inhibitors. Key competitors include Merck’s Keytruda (pembrolizumab) and Bristol-Myers Squibb’s Opdivo (nivolumab).
Imfinzi's market share is estimated at 8-10% of the PD-L1 inhibitor segment, with significant growth potential due to expanded indications.
Key Indications
- Unresectable Stage III NSCLC (2018 approval)
- Extensive-stage SCLC (2019)
- Others: Bladder cancer, head and neck cancers (pending approvals)
Market Penetration and Adoption
- Approved in 2017 in the US
- Rapid uptake in Europe and Asia
- Early-stage commercial data shows steady growth, especially in lung cancers
- Expansion into combination therapies expected to boost demand

Pricing History and Projections
Current Pricing
- US Average Wholesale Price (AWP): Approximately $6,880 per 300 mg vial (as of Q4 2022)
- Bundled Therapy: Often combined with chemotherapies, increasing costs
Price Strategy Factors
- AstraZeneca’s pricing reflects premium positioning as a monoclonal antibody for difficult-to-treat cancers.
- Price erosion occurs due to biosimilar entry, yet biosimilars for PD-L1 inhibitors are not yet available.
Future Price Projections
| Year |
Estimated Wholesale Price per 300 mg vial |
Reasoning and Assumptions |
| 2023 |
$6,880 |
Stable, no biosimilar threat, high demand |
| 2024 |
$6,620 (-3.8%) |
Slight discounting to promote uptake, minimal biosimilar competition |
| 2025 |
$6,300 (-8.4%) |
Entry of biosimilar competitors in 2025, marginal market share loss |
| 2026 |
$6,000 (-12.9%) |
Increased biosimilar presence, pressure on pricing |
| 2027 |
$5,700 (-17.3%) |
Broad biosimilar adoption, potential price-based competition launched |
Biosimilar Impact
Biosimilar versions of PD-L1 inhibitors are in early development phases; market entry is projected around 2025-2026[1]. This will eventually suppress prices, but AstraZeneca may delay aggressive discounts through patent protections and lineup expansion.
Revenue Projections
Using the current price and estimated uptake, projected revenue for AstraZeneca’s Imfinzi in 2023:
- Estimated annual volume: 2 million doses (an approximate, based on uptake trends)
- Revenue = 2 million doses × $6,880 per dose = $13.76 billion
Over next five years, assuming moderate market share growth and price adjustments:

Market Risks
- Biosimilar Competition: Entry around 2025 could cut prices by 20-30%.
- Regulatory Changes: Shift in reimbursement policies could impact profitability.
- Clinical Expansion: Successful approval of additional indications can sustain revenue.
Regulatory and Policy Environment
- US FDA approval granted 2017 for NSCLC
- EMA approval followed in Europe in 2018
- Policies favoring immuno-oncology agents drive adoption
- Reimbursement varies by country; high-cost drugs face scrutiny in health systems with budget constraints
Key Takeaways
- NDC 42799-0962 (Imfinzi) is a leading PD-L1 inhibitor with an established market in lung cancers.
- Current unit prices are stable, around $6,880 per 300 mg vial, with variable global pricing strategies.
- Market share is about 8-10%, with potential for growth depending on expanded indications and combination therapies.
- Price erosion anticipated starting in 2025 due to biosimilar entry, with potential reductions of up to 30%.
- Revenue projections depend on demand, biosimilar competition, and regulatory support, with a gradual decline expected from 2025 onward.
FAQs
1. What factors influence the price of Imfinzi?
Pricing depends on demand, competition, biosimilar entry, manufacturing costs, and reimbursement negotiations across different markets.
2. When are biosimilars expected to enter the market?
Potential biosimilar entry could occur around 2025-2026, impacting prices and market share.
3. How does Imfinzi compare to competitors like Keytruda?
Imfinzi has a narrower approved indication profile but benefits from AstraZeneca’s strategic expansion; pricing is similar but slightly lower than Keytruda’s average wholesale price.
4. What are the key growth drivers for Imfinzi?
