Fda purple book dupilumab biosimilar approved 2026?

Short answer: I don’t have real-time data, but as of my last update (2024) there were no FDA-approved dupilumab biosimilars listed in the Purple Book. If a dupilumab biosimilar was approved in 2026, it would appear in the FDA Purple Book and in FDA press announcements.

How to verify for 2026
- Check FDA Purple Book (biosimilar product information): https://purplebooksearch.fda.gov
- Search for “dupilumab” or the brand name “Dupixent”
- Look for any biosimilar entries with reference product “dupilumab”
- Note the biosimilar product name, sponsor, and approval date; check if it’s also labeled “interchangeable”
- Check FDA biosimilars news/releases for any 2026 approvals
- If you have a specific product name or link, I can help interpret what it means (biosimilar vs. interchangeable)

Would you like me to guide you through a quick check if you can share a link or allow me to look up current FDA listings?
