PA-25-173-Full-Announcement.html

This document is a full announcement for the Systematic Testing of Radionuclides in Preclinical Experiments (STRIPE) grant program (PA-25-173), a funding opportunity from the National Institutes of Health (NIH).

The STRIPE program seeks to support preclinical research projects that study how radiopharmaceutical therapy (RPT) agents affect the biology of normal tissue, tumor cells, and the tumor microenvironment. Proposed projects should test hypotheses on how RPT dynamically impacts cancer biology processes, which can inform the development of new RPT-based clinical trials. Eligible applicant types include small businesses, state/local governments, higher education institutions, nonprofits, and other organizations. This R21 grant provides funding for 2 years, with no clinical trials allowed. The program is funded under the NIH's Cancer Detection and Diagnosis Research (93.394) and Cancer Treatment Research (93.395) grant programs. The application deadline is October 25, 2025, and the estimated award date is July 2026.
