REVCOVI biosimilars — when can they launch?
REVCOVI (ELAPEGADEMASE) · BLA761092 · CHIESI USA INC
Where REVCOVI sits in the biosimilar timeline
BPCIA 12-year reference product exclusivity for REVCOVI extends to 2030 (4 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.
