The National Institutes of Health (NIH) is offering a funding opportunity titled "Systematic Testing of Radionuclides in Preclinical Experiments (STRIPE)" aimed at advancing cancer therapeutics through research projects that utilize radionuclide-based therapies. This initiative specifically seeks R01 research proposals that investigate the effects of various radiation types on normal tissues, tumor cells, and the tumor microenvironment, with a focus on novel targeting strategies and pharmacodynamic biomarkers. The STRIPE program is critical for enhancing the understanding of radiopharmaceuticals in cancer treatment, with applications limited to direct costs of $500,000 per year and a maximum project duration of five years. Interested applicants must adhere to NIH guidelines, with submission deadlines starting January 5, 2025, and can direct inquiries to grantsinfo@nih.gov for further information.
