INFLIXIMAB biosimilars — when can they launch?
INFLIXIMAB (infliximab) · BLA103772 · CENTOCOR INC
Where INFLIXIMAB sits in the biosimilar timeline
BPCIA reference product exclusivity for INFLIXIMAB expired in 2010. 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.
