Lorbrena generics — when can they launch?
Lorbrena (lorlatinib) · Pfizer · 8 active US patents · 0 expired
Where Lorbrena sits in the generic timeline
Long-dated protection: earliest active US patent for Lorbrena extends to 2033 (~7 years out). Generic competition is at least 4 years away. Lifecycle moves (new formulations, label extensions, combination filings) typically execute 18-36 months ahead of cliff.
Under US Hatch-Waxman, a generic enters via an ANDA (Abbreviated New Drug Application) and may file with one of four Paragraph IV certifications attacking the brand's listed patents. If the brand sues within 45 days, a 30-month FDA approval stay is triggered. First Para IV filer typically gets 180-day market exclusivity.
Patent estate by type — active patents
Method-of-use patents only carve out specific indications; generics can launch with a "skinny label" omitting those uses. Composition-of-matter patents block the molecule itself.
- Composition of Matter — 4 patents
- Method of Use — 2 patents
- Formulation — 2 patents
FDA U-codes carved out by Lorbrena patents
Method-of-use patents are listed against specific FDA Patent Use Codes ("U-codes") representing carved-out indications. Generics can launch with a label that omits these uses.
