Enzalutamide fda exclusivity date?

When does enzalutamide’s FDA exclusivity run out?

Enzalutamide (Xtandi) is an FDA-approved product, but the exact “exclusivity date” depends on which protection you mean:

- Patent expiration (governed by patent law, not FDA exclusivity)
- Orphan drug exclusivity (if applicable)
- Exclusivity tied to approval pathways (for example, new-chemical-entity exclusivity or certain application/labeling exclusivities)

The FDA exclusivity date is not the same thing as the day the last patent expires, and different exclusivities can run at different times.

What do people usually mean by “FDA exclusivity” for Xtandi?
