What patent does eli lilly have on foundayo?

I can help, but I need one detail first: which “Foundayo” product are you referring to (and is it spelled exactly that way)?

Eli Lilly’s well-known candidate/product names include Fazirsiran (not Foundayo), and other Lilly pipeline/brand names don’t immediately match “Foundayo.” “Foundayo” might also be a local brand name in a specific country, or it could be a different spelling.

If you tell me the active ingredient (or strength) or the country/market, I can look up the specific Eli Lilly patent(s) associated with it (e.g., compound, formulation, method-of-use, or exclusivity).
