ZALTRAP biosimilars — when can they launch?
ZALTRAP (Ziv aflibercept) · BLA125418 · SANOFI AVENTIS US
Where ZALTRAP sits in the biosimilar timeline
BPCIA reference product exclusivity for ZALTRAP expired in 2024. Biosimilars are eligible for FDA 351(k) approval in the US. Active biosimilar applications and approvals will appear here as they're filed.
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.
