EVKEEZA biosimilars — when can they launch?
EVKEEZA (EVINACUMAB-DGNB) · BLA761181 · REGENERON PHARMACEUTICALS
Where EVKEEZA sits in the biosimilar timeline
BPCIA 12-year reference product exclusivity for EVKEEZA extends to 2033 (7 years from today). Biosimilars cannot be approved by the FDA before this date. Biosimilar developers begin clinical comparability studies 4-6 years before the cliff.
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.
