BEVACIZUMAB | B125085 | GENENTECH
No 12-year reference-product exclusivity is listed in the Purple Book, and the reference product was first approved Feb. 26, 2004 — before BPCIA (March 23, 2010), so any 12-year exclusivity has long expired.
Full-label vs. best-skinny biosimilar entry
| Scenario | Date | Status | Controlling |
|---|---|---|---|
| Best-skinny entry (floor) | Open now | Open now | no live licensure floor |
| Full-label entry | May. 29, 2027 | 10mo 15d remaining | carveable orphan wall |
Minimal carve: Dropping the orphan-walled indication ("TECENTRIQ for the treatment of patients with unresectable or metastatic hepatocellular carcinoma who have not received prior systemic therapy.", protected through 2027-05-29) advances biosimilar entry from the full-label date to now (no remaining licensure floor).
Carve frontier · drop each orphan-walled indication to advance entry

|---|---|---|
| TECENTRIQ for the treatment of patients with unresectable or metastatic hepatocellular carcinoma who have not received prior systemic therapy.(label indication #10) | May. 29, 2027 | Open now(12-yr RPE floor) |
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.
Carveable orphan wall · May. 29, 2027
Orphan-drug exclusivity runs past the licensure floor, but it walls only its specific orphan-designated indication(s). A biosimilar can omit those indications (a “fewer-than-all-conditions” carve-out) and be licensed for the rest now, then add the protected indication back by supplement once the orphan period expires. It is not a licensure gate for the other indications.
Marketing-entry ceiling (litigation risk)
Patents do not gate FDA licensure of a biosimilar — FDA licenses biosimilars (full or carved label) without adjudicating any patent. These are a practical marketing-entry ceiling resolved in the § 262(l) patent dance and ordinary litigation. A formulation/compound patent caps practical skinny entry via litigation (Regeneron v. Mylan); a method-of-use patent is carveable and gates nothing.

Approved Biosimilars
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.
