The Food and Drug Administration (FDA) is offering a funding opportunity titled "Evaluating the Cutaneous Pharmacokinetics of Topical Drug Products Using Pharmacokinetic Tomography," aimed at advancing research on non-invasive technologies for assessing the pharmacokinetics of topical drugs in human skin. This initiative seeks to develop methodologies that accurately measure how effectively topical drugs become available at their site of action, with a focus on creating reproducible non-invasive techniques for cutaneous pharmacokinetics assessment. Eligible applicants include higher education institutions, nonprofits, and governmental organizations, with funding available up to $250,000 for the first year, potentially extendable for a total of four years. Interested parties should submit their applications by April 8, 2024, and can contact Terrin Brown at terrin.brown@fda.hhs.gov for further information.
