Demonstrating Equivalence of Generic Complex Drug Substances and Formulations
October 6, 2017 (8:00 a.m. – 4:00 p.m.), FDA White Oak Campus
The workshop is free to attend and open to the public.
Complex Drug Workshop Registration
The FDA is continually interested in new analytical methods and innovative in vitro testing methodologies that support establishment of equivalence of generic drug products and facilitate the regulatory review process. Complex drug substances (e.g., peptides, polymers, and naturally derived drug substances) and complex formulations (e.g., liposomes, emulsions, suspensions, and polymeric materials) present unique development and regulatory challenges for demonstrating active ingredient sameness and/or bioequivalence. New analytical tools and in vitro tests may overcome these hurdles and thereby reduce product development time and cost, and inform regulatory decisions. To help support the development of these new tools, fees from the first Generic Drug User Fee Amendments (GDUFA I: 2012-2017) were allocated to regulatory science initiatives based on public and industry input.
In this workshop on complex drug development, the FDA will highlight outcomes and impacts from GDUFA I research related to complex drug products as well as:
- Share FDA’s current experiences on the evaluation and characterization of critical quality attributes for complex drug substances and formulations.
- Discuss current and future innovative approaches for the development and regulatory review of complex drug product equivalence.
- Obtain input from various stakeholders on how to conduct and assess critical quality attribute measurements to demonstrate equivalence of complex drug products; and
- Request comments on these topics.
To register, go to: Complex Drug Workshop Registration on or before Sept 30, 2017. Registration on the day of the public workshop will be provided on a space available basis beginning at 7:30 a.m. Webcast Link for Online Attendees: https://collaboration.fda.gov/complexgenericdrugs/.
