IMETELSTAT SODIUM generics — when can they launch?
IMETELSTAT SODIUM (IMETELSTAT SODIUM) · · 12 active US patents · 0 expired
Where IMETELSTAT SODIUM sits in the generic timeline
All listed Orange Book patents for IMETELSTAT SODIUM have expired. Generic entry is permitted, and ANDA filers can launch without patent infringement risk. Hatch-Waxman exclusivity (NCE/ODE/PED) may still apply if recently approved.
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.
- Method of Use — 10 patents
- Composition of Matter — 2 patents
FDA U-codes carved out by IMETELSTAT SODIUM 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.
