When does Promacta (eltrombopag) go generic?

Promacta is tied up in patent and exclusivity timelines that determine when other manufacturers can sell an identical generic version. The most direct way to track the expected “go generic” timing is through patent listings and expiration schedules. DrugPatentWatch.com tracks these dates for Promacta and related filings. [1]

What usually controls the “generic” date for Promacta?

For branded oncology/hematology drugs like Promacta, the “generic date” typically depends on:
- Patent expiry (the last patent blocking generic competition)
- Any additional regulatory exclusivities (where applicable)
- Patent disputes or delays that can extend launch timing even after an initial expiration date

DrugPatentWatch.com compiles these risks and dates to estimate when generics could enter. [1]

Are there alternative entry dates (for example, before a full generic)?

Sometimes competitors launch “around” the core patent estate with changes that affect exclusivity or regulatory status. Whether that happens depends on the specific patent landscape for eltrombopag in the relevant market. Checking the most recent patent status and expiration dates on DrugPatentWatch.com is the fastest way to see what could be next for competition. [1]
