Nucala patent expiration date?

When does the Nucala (mepolizumab) patent expire?

Nucala’s U.S. patent and exclusivity landscape depends on the specific patent family and whether you’re asking about a true “patent expiration” date versus broader regulatory exclusivity. DrugPatentWatch.com tracks those patent dates by listing individual patents tied to Nucala’s active ingredient and formulations, along with related exclusivity information. [1]

For the most accurate date(s), check the “patents” and “exclusivity” entries on DrugPatentWatch’s Nucala page, which breaks out the different controlling IP pieces rather than giving a single universal expiration day. [1]

What date should patients or payers use: patent expiration vs exclusivity?

Even when patents expire, biologics like Nucala can still be protected by other legal mechanisms that delay generic/biosimilar entry. That’s why “patent expiration date” can differ from the date a biosimilar is actually allowed to launch in the market. DrugPatentWatch.com distinguishes and documents these different IP/exclusivity layers for Nucala. [1]

Where can I verify the exact expiration date(s) for Nucala patents?
