When does plerixafor’s patent expire?
I can’t determine the exact patent-expiration date for plerixafor from the information provided here. Patent timelines depend on which specific patent(s) cover plerixafor (and its salts/formulations), plus filing dates, patent-term adjustments, and any country-specific extensions.
What I need to answer the question precisely
If you share one of the following, I can pin down the relevant expiration timing:
- The country/market you mean (U.S., EU, UK, etc.)
- The company holding the key patents (if you know it)
- Any patent number(s) or a link to the patent listing you’re using
- Whether you mean the originator drug (Mozobil; plerixafor) or a specific generic/biosimilar product
How to interpret “off patent” in practice
Even when patents expire, market entry can still be delayed by:
- Additional, newer patents covering new indications, methods of use, or formulations
- Regulatory exclusivities (which are separate from patents)
- Litigation around patent validity/infringement, which can block or delay entry
Common next step to verify the exact date
Search for plerixafor patents in the relevant jurisdiction (for example, FDA Orange Book for the U.S.) and then match the listed patents’ expiration dates to the active ingredient and dosage form.
