2019 – ASCO-SITC – NBTXR3 with anti-PD-1 in advanced HNSCC or NSCLC

Clinical Data NBTXR3, Congress Abstracts, Head & Neck, Lung

Despite proven efficacy, a limited number of patients (pts) with recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) or metastatic non-small cell lung cancer (NSCLC) benefit from anti-PD-1 treatment. Indeed, most pts do not respond to initial therapy due to intrinsic re-sistance to checkpoint inhibition. There is thus an important unmet medical need for a curative treatment in these pts and converting the local immune microenvironment to a “hot” phenotype may help to overcome therapeutic resistance.

2019 – ICHNO – Phase I/II NBTXR3 in HNSCC

Clinical Data NBTXR3, Congress Abstracts, Head & Neck

Hafnium oxide nanoparticles, NBTXR3, were developed to augment tumor-localized high energy deposit once activated by ionizing radiation such as Intensity Modulated Radiation Therapy (IMRT) and thus to increase tumor cell death compared to the same dose of radiation. NBTXR3 is characterized by a single intratumoral (IT) administration and fits into standard radiotherapy schedule with no change in patient’s care pathway, treatment protocol or equipment. […]

2019 – ASCO GI – Phase I/II NBTXR3 in HCC and Liver Metastasis

Clinical Data NBTXR3, Congress Abstracts, Liver

Compared to younger individuals, elderly patients with head and neck squamous cell carcinoma (HNSCC) have limited therapeutic options. Despite representing approximately 47% of the affected population with an increasing incidence, older patients are underrepresented from HNSCC prospective clinical trials further limiting their therapeutic options. […]

2019 – Bulletin Cancer – NBTXR3 improves pathological response

Miscellaneous, NO-RIGHTS, Publications

Doubling complete histological response in sarcomas with radiation therapy using nanoparticles (Hafnium oxide, NBTXR3), a phase III trial.

2019 – The Lancet Oncology – Act.In.Sarc

Clinical Data NBTXR3, NO-RIGHTS, Publications, STS

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

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. […]

2018 – ASTRO – NBTXR3 Anti-Tumor Immune Response

Clinical Data NBTXR3, Congress Abstracts, STS

Soft tissue sarcoma (STS) is a rare type of cancer, which occurs in tissues connecting, supporting and/or surrounding other structures of the body, like muscle, fat, etc. More than 50 subtypes of STS exist, characterized by a strong propensity to local recurrence and metastatic spreading. Consistently, the immune microenvironment in sarcomas is highly variable. A new class of high electron density material, hafnium oxide, was designed at the nanoscale to efficiently absorb ionizing radiation from within the tumor cells and increase the dose deposition into the tumor. […]

2018 – OncoRad – NBXTR3 in HNSCC and NSCLC with anti-PD1

Clinical Data NBTXR3, Congress Abstracts, Head & Neck, Lung

Recent clinical studies have demonstrated the efficacy of anti-PD-1 in recurrent/metastatic HNSCC and upfront metastatic NSCLC patients. However, most patients with recurrent/metastatic HNSCC demon-strate innate (primary) resistance to checkpoint inhibition and do not respond to initial therapy and only a subset of metastatic HNSCC/NSCLC patients benefits from this treatment. […]

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

Congress Abstracts, In Vivo

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 – SIOG – NBTXR3 In Elderly With HNSCC

Clinical Data NBTXR3, Congress Abstracts, Head & Neck
