Brief Summary

This study evaluates the clinical impact of AGuIX® nanoparticles in combination with Fractionated Stereotactic Radiation in oligo brain metastases.

Detailed Description

AGuIX® (Activation and Guidance of Irradiation by X-ray, NH TherAguix) are Gadolinium chelated polysiloxane based nanoparticles with Magnetic Resonance contrast properties, able to accumulate in the tumor through the enhanced permeability and retention effect and sufficiently small (sub-5 nm diameter) to allow for renal clearance.

AGuIX® nanomedicine can be used as:

• Positive contrast agent for Magnetic Resonance Imaging (MRI). It displays higher efficacy than commercial contrast agents and so it can be used to delineate precisely the tumors.
• A booster of Radiotherapy during the radiotherapy protocol, after the localization of the tumor.

This is permitted by the high radiosensitizing potential of AGuIX® that allows a local increase of efficacy of X-ray damages. French and international groups have demonstrated the radiosensitizer effect of AGuIX® to improve the efficacy of radiotherapy.

Thanks to a difference in porosity between the vascular networks, AGuIX® penetrates and resides in tumor tissues, but not in healthy tissues.
