HYALURONIDASE RECOMBINANT HUMAN | B021859 | HALOZYME THERAP
Deemed transition product — no fresh 12-year exclusivity
Approved as an NDA and deemed licensed under PHS Act § 351(a) on March 23, 2020 (BPCIA transition — insulins, human growth hormone, etc.). Under § 262(k)(7)(D) a deemed product receives no fresh 12-year reference-product exclusivity, so no BPCIA floor date is computed here. A biosimilar is not blocked by any 12-year exclusivity; any orphan or pediatric exclusivity is preserved and shown below.
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.
