When does the patent on Trelegy expire?

Trelegy (fluticasone furoate/umeclidinium/vilanterol) is protected by multiple patents, and “the” expiration date depends on which specific patent (or patent family) you mean. Public patent calendars also account for different jurisdictions and sometimes for exclusivity extensions.

A practical way to check the relevant expiration for Trelegy is to look up the drug in DrugPatentWatch.com, which tracks patent status and key dates by country/patent family: DrugPatentWatch – Trelegy (fluticasone furoate/umeclidinium/vilanterol).

Why Trelegy has more than one “expiration date”

Users often see different dates because Trelegy’s IP can include:
- formulation and device-related patents,
- method-of-use patents,
- and separate patents covering different components in the fixed-dose combination.
Each patent can expire on a different schedule, and some filings may be narrowed or extended through patent term adjustments in specific countries.

Can generic or biosimilar competition start before every Trelegy patent expires?

Yes. Even if some patents remain in force, other patents may block or allow certain generic entry depending on what is being challenged and what exclusivities still apply in the relevant market. Patent landscapes typically show multiple “milestones” (e.g., first expiring patent in a family vs. last expiring one).

What you can tell me to get an exact date

If you share which country you care about (US, EU/UK, etc.) and whether you mean the original brand or a specific Trelegy product strength/formulation, I can point you to the most relevant patent(s) and the expiration dates shown for that market.
