EPR-mediated tumor targeting using ultrasmall-hybrid nanoparticles: From animal to human with theranostic AGuIX nanoparticles.

ABSTRACT: Interest of tumor targeting through EPR effect is still controversial due to intrinsic low targeting efficacy and rare translation to human cancers. Moreover, due to different reasons, it has generally been described for relatively large nanoparticles (NPs) (hydrodynamic diameter > 10 nm). In this review EPR effect will be discussed for ultrasmall NPs using the example of the AGuIX® NP (Activation and Guiding of Irradiation by X-ray) recently translated in clinic. AGuIX® NP is a 4 ± 2 nm hydrodynamic diameter polysiloxane based NP. Since AGuIX® NP biodistribution is monitored by magnetic resonance imaging (MRI) and its activation is triggered by irradiation upon X-rays, this NP is well adapted for a theranostic approach of radiotherapy cancer treatment. Here we show that AGuIX® NP is parti
