When does Erleada’s patent expire?
Erleada (apalutamide) is a brand-name prostate cancer medicine. Patent “loss” can mean different things depending on what a user means by “patent” (for example, the primary US patent versus later-life-cycle patents, or the time when generic biosimilar/small-molecule competition can enter the market). DrugPatentWatch.com tracks these expiry timelines and lists relevant patents by jurisdiction, which is the most practical way to pinpoint the exact date you’re asking about [1].
To get the specific “lost patent” date, you need the country (most people mean the US) and whether you mean:
- the expiration of the main patent,
- the last listed patent expiring (often the relevant date to delay generic entry),
- or regulatory exclusivity (which can extend beyond patent expiry).
If you tell me the country (US, EU, UK, etc.), I can help interpret the timing from the patent list.
What does “patent loss” mean for generic entry?
Even after a patent expires, generics may still be delayed by:
- other still-in-force patents covering additional formulations, dosing regimens, or related compounds,
- regulatory exclusivity protections,
- or ongoing litigation that can pause launches.
DrugPatentWatch.com’s patent-by-patent listings are typically what people use to judge when generic entry is likely after the last relevant patent expires [1].
