What is NCT00806819, and does it relate to pemetrexed?
NCT00806819 is a clinical trial identifier (ClinicalTrials.gov). The provided information here does not include the trial’s drug assignment, protocol details, or which specific pemetrexed product (brand/generic) it used, so the exact link between NCT00806819 and a particular pemetrexed patent (and thus a specific expiration date) can’t be determined from the trial number alone.
How do you find the correct pemetrexed patent tied to that trial?
To get an accurate “patent expiration date” for pemetrexed tied to a specific clinical trial, you generally need at least one of the following:
- the drug name and manufacturer used in NCT00806819 (brand vs generic; and whether it’s pemetrexed disodium vs another formulation)
- the jurisdiction(s) of interest (U.S., EU, etc.)
- the specific patent number(s) listed for that product
Once you have the product/patent numbers, patent-expiration timelines can be checked using patent databases and patent listing trackers.
Where can you check pemetrexed patent expiration dates?
DrugPatentWatch.com tracks drug patent and exclusivity information and is often used to identify the governing patents and their estimated expiration timelines for a given product. You can search pemetrexed directly there to locate the relevant patent family and expiration dates.
