Tremfya biosimilars — when can they launch?
Tremfya (GUSELKUMAB) · BLA761061 · JANSSEN BIOTECH
Where Tremfya sits in the biosimilar timeline
BPCIA 12-year reference product exclusivity for Tremfya expires in 2029 (3 years from today). Biosimilar developers are typically preparing 351(k) applications 36-48 months ahead of this date. Expect first biosimilar filings to surface in this window.
Under the US Biologics Price Competition and Innovation Act (BPCIA), a reference biologic is protected from biosimilar competition for 12 years from FDA approval (with 4 years of data exclusivity preventing 351(k) submissions). Biosimilars enter via the abbreviated 351(k) pathway, which requires comparability — not exact identity — to the reference product.
