The National Institutes of Health (NIH) is offering a funding opportunity titled "Microbial-based Cancer Imaging and Therapy - Bugs as Drugs" (R21 Clinical Trial Not Allowed), aimed at advancing research in the use of microorganisms for cancer treatment and diagnostics. This initiative invites grant applications that explore the interactions between microorganisms, tumors, and the immune system, focusing on their potential to develop innovative strategies for cancer imaging and therapeutics, particularly for solid tumors and oral cancers. The program supports exploratory and developmental research with a maximum budget of $275,000 over two years, encouraging multidisciplinary collaboration to address significant challenges in cancer therapy. Applications are due by May 7, 2025, and interested parties can reach out to NIH Grants Information at grantsinfo@nih.gov for further inquiries.
