Study Summary

The purpose of this study is to determine whether AGuIX (Activation and Guidance of Irradiation by X-ray) gadolinium-based nanoparticles make radiation work more effectively in the treatment of patients with brain metastases that are more difficult to control with stereotactic radiation alone.

Primary Outcome

Assessed with Response Assessment in Neuro-Oncology (RANO) - Brain Metastasis Guidelines Time to local failure on a per metastasis basis will be performed using the log-rank test.
