The Prescription Drug User Fee Act (PDUFA) was created by Congress in 1992 and authorizes FDA to collect fees from companies that produce certain human drug and biological products. Since the passage of PDUFA, user fees have played an important role in expediting the drug approval process.

PDUFA must be reauthorized every five years, and was renewed in 1997 (PDUFA II), 2002 (PDUFA III), 2007 (PDUFA IV), and 2012 (PDUFA V) and 2017 (PDUFA VI). On August 18, 2017, the President signed into law the Food and Drug Administration Reauthorization Act (FDARA), which includes the reauthorization of PDUFA through September 2022. PDUFA VI will provide for the continued timely review of new drug and biologic license applications.

What is a human drug application?
PDUFA levies a user fee on certain human drug applications. Under PDUFA, the term human drug application means an application for

  • approval of a new drug submitted under section 505(b) of the Federal Food, Drug, and Cosmetic Act (FD&C Act), or
  • licensure of certain biological products under section 351(a) of the Public Health Service Act (PHS Act).
What are application fees?
Each person that submits a human drug application is assessed an application fee as follows:
  •  A human drug application for which clinical data (other than bioavailability or bioequivalence studies) with respect to safety or effectiveness are required for approval is assessed a full application fee.
  •  A human drug application for which clinical data with respect to safety or effectiveness are not required for approval is assessed one- half of a full fee.

Human drug application fees are due when the application is submitted.

Supplements with unpaid fees  submitted prior to PDUFA VI will not automatically be considered acceptable for filing once PDUFA VI takes effect in FY 2018.  Applicants may submit a new supplement in FY 2018 under PDUFA VI, which will not incur a supplement fee.

  • Designated Orphan Drug or Indication
    • An application for a prescription drug product that has been designated as a drug for a rare disease or condition, under section 526 of the Act, is not subject to an application fee unless the application includes an indication for other than a rare disease or condition.
