New Paragraph IV Listings – Some Interesting Observations
The FDA’s paragraph IV (PIV) database is designed to give applicants and potential applicants information relative to first-to-file opportunities. FDA does this for two reasons: 1) it gives applicants assurance that their product is a first-to-file if the acknowledgement date (date acceptable for filing) on their letter from FDA officially receiving their application matches the date of submission in the PIV database. This has eliminated the many calls to the Office of Generic Drugs (OGD) to find out if their submitted application holds a potential first-to-file seat; 2) the listing also informs potential applicants that at least one ANDA has been submitted with a PIV certification and allows others to decide if they wish to enter the fray and expose themselves to litigation.
