The Food and Drug Administration (FDA) is inviting applications for the Minor Use Minor Species Development of Drugs (R01) grant, aimed at supporting the development of new animal drugs for minor uses in major species or any uses in minor species. Eligible applicants must have an active Investigational New Animal Drug (INAD) file with the FDA and must hold a minor use or minor species designation for the drug under investigation, ensuring compliance with regulatory standards. This initiative underscores the FDA's commitment to enhancing veterinary drug development for underserved markets, with grants providing up to $250,000 annually for one-year projects, potentially extendable for long-term studies. Interested parties should submit their applications by the specified deadlines, with the next due date on July 29, 2024, and can contact Terrin Brown at terrin.brown@fda.hhs.gov for further information.
