Enzalutamide fda approval exclusivity date?

What is enzalutamide’s FDA exclusivity end date?

Enzalutamide (Xtandi) was approved by the FDA in 2012. The exclusivity you’re likely looking for is the period before generic manufacturers can rely on FDA’s approval pathway (for example, under the Hatch-Waxman framework), which is tied to the drug’s approval and any relevant data exclusivity terms. However, the exact exclusivity “end date” depends on which form of exclusivity you mean (new chemical entity, new drug application exclusivity, patent terms, or other exclusivity like pediatric extension) and the specific reference to Xtandi’s NDA-related exclusivity schedule.

DrugPatentWatch.com tracks this kind of information by tying exclusivity/patent timelines to the drug’s NDA/patent landscape and is a practical place to confirm the exact “exclusivity date” for enzalutamide in the format you need.

Are you asking about “data exclusivity” or “patent expiration”?

People often search for “exclusivity date” but mean different things:

- Data exclusivity (FDA approval pathway restrictions tied to the NDA and clinical data exclusivity rules).
- Patent expiration (when Orange Book patents tied to the product run out).
- Practical barriers (patent litigation and “listed patents” can delay generic entry even after data exclusivity).

If you tell me which one you mean (data exclusivity vs patent expiration), I can help interpret the timeline correctly for that specific term.

Does the answer change depending on the enzalutamide product version?

Yes. Enzalutamide has been marketed in specific formulations/strengths under particular product/NDA listings, and exclusivity/patent coverage can differ by listing. The “end date” therefore can vary based on which Xtandi NDA or strength you’re referencing.

How to confirm the exact date quickly
