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. […]

2019 – Radiother Oncol – NBTXR3 improves cGAS-STING activation

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. […]

2018 – ASCO – NBTXR3 generates an anti-tumor immune response

The enclosed abstract was presented at the 13th Journées cancéropole Grand Sud-Ouest at Poitiers. The abstract Hafnium oxide nanoparticles as an emergent promising treatment for solid tumors describes how hafnium oxide nanoparticles were designed at the nanoscale in the form of crystalline 50nm-particles to efficiently absorb ionizing radiation and increase the radiation dose deposited – “hot spots” of energy deposit – from within the tumor cells for efficient cell killing. […]

2018 – ASTRO – NBTXR3 in solid tumors

To improve radiotherapy (RT) in terms of tumor response and to reduce irradiation of healthy tissues, innovative therapeutic approaches are needed. In response, NBTXR3, injectable hafnium oxide nanoparticles, was developed for the treatment of solid tumors. Once injected intratumorally, NBTXR3 can deposit high energy within tumors only when activated by an ionizing radiation source, like current standard RTs. […]

2018 – ASCO – NBTXR3 in the treatment of liver cancer: a phase I/II trial

With recent advances in radiation delivery techniques, an increasing number of cancer patients undergo radiotherapy. However, due to the non-targeted nature of radiotherapy, doses are limited by potential toxicity to surrounding normal tissue. Thus, a major challenge remains to develop new strategies to improve the tumor selectivity of radiation therapy. […]

2018 – ESTRO – Hafnium Oxide Nanoparticles and Radiotherapy: A Promising New Treatment Strategy

With recent advances in radiation delivery techniques, an increasing number of cancer patients undergo radiotherapy. However, due to the non-targeted nature of radiotherapy, doses are limited by potential toxicity to surrounding normal tissue. Thus, a major challenge remains to develop new strategies to improve the tumor selectivity of radiation therapy. […]

2018 – AACR – Activation of the cGAS-STING pathway by NBTXR3

Recent studies reported that radiotherapy could activate the cGAS-STING pathway, which plays a fundamental role in the immune response to cytoplasmic DNA, by activation of the transcriptional factor IRF3, leading to expression of interferon-beta. Moreover, cGAS-STING activation appears to be an important component for tumor resident Antigen-Presenting Cells activation, a crucial step for induction of CD8+ T cell response against tumor derived antigens. […]
