What is NDC 58657-0810?
The National Drug Code (NDC) 58657-0810 corresponds to Immunoflu, a biosimilar version of the biologic drug Rituximab, marketed by Celltrion. It targets non-Hodgkin’s lymphoma, chronic lymphocytic leukemia, and other autoimmune conditions, competing with the originator product, Rituxan (Rituximab, by Roche).
Market Landscape
Current Market Size
The global Rituximab market was valued at approximately USD 6.1 billion in 2022. The US accounted for about 35% of the global market, driven by high prevalence rates and established treatment protocols.[1]
Key Competitors
- Rituxan (Roche)
- Truxima (Celltrion): Biosimilar launched in 2018
- Ruxience (Pfizer): FDA-approved biosimilar
- Sandoz’s Rixathon and other biosimilars
Prescribing Trends
Biosimilars have gained acceptance due to cost savings. In 2022, biosimilar Rituximab sales increased by 45%, capturing a significant market share in the US, which is projected to grow at 12-15% annually through 2027.[2]
Regulatory Environment
- FDA approved biosimilars, including Celltrion’s Truxima, since 2018.
- Patent expirations of originator products in 2018-2020 open market opportunities.
