The Food and Drug Administration (FDA) is forecasting a funding opportunity titled "Utilizing Real-World Data and Algorithmic Analyses to Assess Post-Market Clinical Outcomes in Patients Switching Amongst Therapeutically Equivalent Complex Generic Drug Products and Reference Listed Drugs (U01)." This initiative aims to develop and test an AI- or ML-based algorithmic model utilizing real-world data to enhance post-market surveillance of complex generic drug products, addressing the need for effective monitoring of therapeutic equivalence and regulatory decision-making. The funding opportunity is significant as complex generic drugs are increasingly prevalent in the marketplace, necessitating modernized surveillance approaches to ensure patient safety and efficacy. Interested applicants can apply for a cooperative agreement with an award ceiling and floor of $300,000, and should direct inquiries to Terrin Brown at terrin.brown@fda.hhs.gov or by phone at 240-338-7494.
