Where EBGLYSS sits in the biosimilar timeline

BPCIA 12-year reference product exclusivity for EBGLYSS 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.
