Nucala (dupilumab) biosimilars – what you need to know

Topic Summary
What is a biosimilar? A biologic product that is highly similar to a reference biologic (in this case, Nucala/dupilumab) in terms of structure, biological activity, safety, purity, and potency. Biosimilars are approved based on a “totality‑of‑evidence” package that includes analytical testing, animal studies, and at least one well‑designed clinical study (or studies) that demonstrates no clinically meaningful differences in efficacy and safety.
Why are biosimilars important? They offer the same therapeutic benefit as the original drug, but typically at a lower cost, which can improve patient access and reduce healthcare spending.

1. Current regulatory status (2026)

Region Status Approved biosimilar(s) Manufacturer
United States (FDA) No dupilumab biosimilar approved as of 2026 – –
European Union (EMA) 1 dupilumab biosimilar approved Dupixent generic (dupilumab) UCB Pharma
Other regions Various national approvals (e.g., Canada, Japan, Australia) 1–2 biosimilars Varies (often UCB, Boehringer Ingelheim, or local manufacturers)

Bottom line: If you live in the U.S., there is currently no FDA‑approved dupilumab biosimilar. In the EU and many other countries, a biosimilar (marketed simply as “dupilumab” or “Dupixent generic”) is available.
