Revlimid generics — when can they launch?
Revlimid (lenalidomide) · Bristol-Myers Squibb · 12 active US patents · 0 expired
Where Revlimid sits in the generic timeline
Imminent generic cliff: earliest active US patent for Revlimid expires in 2027 (~1 year from today). ANDA filers are likely already preparing Paragraph IV certifications. Expect first-filer 180-day exclusivity competition imminently.
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 — 6 patents
- Method of Use — 6 patents
FDA U-codes carved out by Revlimid 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.
| U-code | Description |
