Nanobiotix est une entreprise pionnière en nanomédecine depuis plus de 10 ans. L’idée est de développer une approche innovante, différente des approches classiques des sociétés pharmaceutiques ou biotechnologiques : une nouvelle façon de traiter les patients grâce à la nanophysique appliquée au cœur de la cellule. Au fil des ans, de nombreuses publications et abstracts ont été publiés dont une partie importante a été réunie dans cette bibliographie en ligne de Nanobiotix.

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

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.

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.

2019 – The Lancet Oncology – Act.In.Sarc

Pathological complete response to preoperative treatment in adults with soft-tissue sarcoma can be achieved in only a few patients receiving radiotherapy. This phase 2–3 trial evaluated the safety and efficacy of the hafnium oxide (HfO2) nanoparticle NBTXR3 activated by radiotherapy versus radiotherapy alone as a pre-operative treatment in patients with locally advanced soft-tissue sarcoma. Act.In.Sarc is a phase 2–3 randomised, multicentre, international trial. Adults (aged ≥18 years) with locally advanced soft-tissue sarcoma of the extremity or trunk wall, of any histological grade, and requiring preoperative radiotherapy were included. […]

2010 – Concept of NBTXR3 – Borghi et al.

La nanotechnologie permet une gestion et un assemblage de matériaux sans précédent dans l’histoire des produits utilisés en santé humaine. Cette révolution est apportée par la possibilité d’utiliser de nouveaux mécanismes thérapeutiques et de dissocier les différentes fonctions de la substance médicamenteuse (distribution, effet thérapeutique…), ce qui était jusqu’ici impossible avec les médicaments classiques.

2016 – Phase I data NBTXR3 Soft Tissue Sarcoma – Bonvalot et al.

This phase I study aimed to determine the recommended dose (RD), safety profile, and feasibility of a procedure combining intratumoral injection of hafnium oxide nanoparticles (NBTXR3; a radioenhancer) and external beam radiotherapy (EBRT) for preoperative treatment of adults with locally advanced soft tissue sarcoma (STS). Patients had a preoperative indication of EBRT for STS of the extremity or trunk. Baseline tumor volume (TV) was calculated by MRI. NBTXR3 was injected percutaneously into tumors at 53.3 g/L. Dose escalation was based on four levels equivalent to 2.5%, 5%, 10%, and 20% of baseline TV. NBTXR3 was visualized in the tumor 24 hours postinjection, and EBRT was initiated (50 Gy over 5 weeks).
