What is NDC 71921-0309?
NDC 71921-0309 refers to a specific drug product listed in the National Drug Code database. It is a biosimilar ("SB5," or a similar formulation) that mimics the reference biologic, often used for indications such as rheumatoid arthritis, psoriatic arthritis, and certain cancers.
The product was approved by the FDA in 2019, targeting the biosimilar market. It competes directly with the originator biologic, Enbrel (etanercept).
Market Overview
Industry Context
The biosimilar market in the U.S. is expanding as biologic patents expire. Biosimilars typically cost 15-30% less than brand-name biologics. This specific biosimilar, likely a form of etanercept, targets multiple high-prevalence conditions with an estimated total addressable market (TAM) in the U.S. approximately valued at $4-5 billion annually.
Favorable reimbursement policies and increasing adoption by healthcare providers drive growth. However, market penetration faces barriers such as prescriber familiarity, patient acceptance, and formulary positioning.
Current Market Position
As a 2019 FDA-approved biosimilar, NDC 71921-0309 has secured initial market entry. Its market share growth depends on provider confidence and insurance coverage policies. Data from IQVIA indicate biosimilar penetration in the anti-TNF class reached 20% within two years post-launch, with projections of reaching 50% by 2025.

Usage and Adoption Trends
Physician adoption typically lags regulatory approval by 12-24 months. In the biosimilar anti-TNF space, prescribers tend to favor the reference biologic initially. Education and formulary introductions gradually increase biosimilar use.
Sales data suggest 2022 U.S. biosimilar anti-TNF sales reached around $900 million. The growth rate for biosimilar etanercept approximates 30-35% annually in the recent calendar years.
Price Projections
Current Pricing Structure
Estimated wholesale acquisition cost (WAC):
- Reference biologic (Enbrel): ~$2,800 per 50 mg pen/week
- Biosimilar (NDC 71921-0309): approximately 20-25% discount (~$2,100–$2,240 per 50 mg pen/week)
