The Food and Drug Administration (FDA) is forecasting a funding opportunity titled "Evaluating the Cutaneous Pharmacokinetics of Topical Drug Products Using Pharmacokinetic Tomography," which requires a clinical trial. This cooperative agreement aims to support research and development of non-invasive technologies to accurately measure the pharmacokinetics of topically applied drugs within the skin, facilitating the demonstration of bioequivalence for topical products. The FDA anticipates awarding one grant with a funding amount of $250,000, and interested applicants can reach out to Terrin Brown at terrin.brown@fda.hhs.gov or by phone at 240-338-7494 for further details. Applications are due in fiscal year 2024, and organizations may submit multiple distinct applications, adhering to specific submission guidelines.
