# Translation of a Bismuth-Gadolinium Nanoparticle for MR-guided Radiation Therapy

> **NIH NIH R01** · DANA-FARBER CANCER INST · 2020 · $619,902

## Abstract

Project Summary
Recent preclinical and clinical results have demonstrated the safety and efficacy of
nanoparticle-amplified radiation therapy. In parallel, MR-guided radiation therapy is an
emerging paradigm that would benefit from specific contrast agents. This Academic-
Industrial Partnership will leverage these current trends by designing, developing and
rigorously testing a novel nanoparticle for MR-guided radiation therapy. Our supporting
data consists of extensive physical and biological characterization of gadolinium and
bismuth-gadolinium based nanoparticles, including in vivo biodistribution, imaging and
therapy results in multiple tumor models. In this project, we will develop and optimize a
direct high-yield synthesis process for bismuth-gadolinium nanoparticles and perform
extensive toxicity and therapy evaluation in a translational model under clinical delivery
schedules and conditions. Our innovative and highly translatable imaging and therapy
concept is compatible with current and emerging clinical practice and could offer a
substantial clinical benefit with minimal patient risk.
