PAVBLU biosimilars — when can they launch?
PAVBLU (AFLIBERCEPT-AYYH) · BLA761298 · AMGEN INC
Where PAVBLU sits in the biosimilar timeline
BPCIA 12-year reference product exclusivity for PAVBLU extends to 2036 (10 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.
