No 12-year reference-product exclusivity is listed in the Purple Book, and the reference product was first approved Jun. 16, 2025 — before BPCIA (March 23, 2010), so any 12-year exclusivity has long expired.

Each rung drops one orphan-designated indication (sourced from the FDA Orphan Drug Product designation database and matched to the reference label); dropping the latest-walled indication advances biosimilar entry to the next constraint, until every orphan wall is carved and entry reaches the RPE floor.
Marketing-entry ceiling (litigation risk)
No listed or discovered patents.
Disclaimer: Identifying an available carve-out is not a prediction that FDA will approve the particular carved label, nor that marketing it is free of infringement risk. For biologics, availability turns on exclusivities, not patents: FDA licenses a biosimilar (full or carved label) without adjudicating any patent, and patent disputes run through the § 262(l) patent dance and ordinary litigation, outside this availability view.
No patent or exclusivity listings for this strength.
