2021 – NBTXR3 Radiotherapy-Activated Functionalized Hafnium Oxide Nanoparticles Show Efficient Antitumor Effects Across a Large Panel of Human Cancer Models

In Vitro, In Vitro in Vivo NBTXR3, NO-RIGHTS, Publications

The side effects of radiotherapy induced on healthy tissue limit its use. To overcome this issue and fully exploit the potential of radiotherapy to treat cancers, the first-in-class radioenhancer NBTXR3 (functionalized hafnium oxide nanoparticles) has been designed to amplify the effects of radiotherapy. […]

2019 – Radiother Oncol – NBTXR3 improves cGAS-STING activation

In Vitro, In Vitro in Vivo NBTXR3, NO-RIGHTS, Publications

The cGAS-STING pathway can be activated by radiation induced DNA damage and because of its important role in anti-cancer immunity activation, methods to increase its activation in cancer cells could provide significant therapeutic benefits for patients. We explored the impact of hafnium oxide nanoparticles (NBTXR3) activated by radiotherapy on cell death, DNA damage, and activation of the cGAS-STING pathway. […]

2014 – NBTXR3 concept and dose enhancement – Marill et al.

In Vitro, In Vitro in Vivo NBTXR3, NO-RIGHTS, Publications

Hafnium oxide, NBTXR3 nanoparticles were designed for high dose energy deposition within cancer cells when exposed to ionizing radiation. The purpose of this study was to assess the possibility of predicting the in vitro the biological effect of NBTXR3 nanoparticles when exposed to ionizing radiation. Cellular uptake of NBTXR3 nanoparticles was assessed in a panel of human cancer cell lines (radioresistant and radiosensitive) by transmission electron microscopy. The radioenhancement of NBTXR3 nanoparticles was measured by the clonogenic survival assay.

2012 – Efficacy of NBTXR3 in vitro and in vivo – Maggiorella et al.

In Vitro, In Vitro in Vivo NBTXR3, In Vivo, NO-RIGHTS, Publications

There is considerable interest in approaches that could improve the therapeutic window of radiotherapy. In this study, hafnium oxide nanoparticles were designed that concentrate in tumor cells to achieve intracellular highenergy dose deposit. Materials & methods: Conventional methods were used, implemented in different ways, to explore interactions of these high-atomicnumber nanoparticles and ionizing radiation with biological systems.
