2017 – Abstract – 13th Journées cancéropole GSO – HfO2 nanoparticles in solid tumors

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 – ASCO GI – A phase I/II trial of NBTXR3 nanoparticles activated by SBRT in the treatment of liver cancers

The physical mode of action of NBTXR3 may represent a breakthrough approach for the local treatment of liver cancers, as it does not engage liver and renal functions, i.e. nanoparticles are not metabolized and not excreted by kidney. A phase I/II trial has been implemented for the treatment of hepatocellular carcinoma and liver metastasis. […]

2017 – Abstract – THNO – NBTXR3 in combination with IMRT in patients with locally advanced HNSCC

At the 2017 THNO in Nice, France, prof. C. Le Tourneau presented preliminary results of NBTXR3 in patients suffering from HNSCC. The treatment was associated with a positive safety profile, and preliminary effiacy evaluation, the local Complete Response rate is 83 % (dose level15% and 22%), with a duration of response of 22 months.

2017 – Abstract SITC Conference Maryland – Clinical

Soft tissue sarcoma (STS) is a large and heterogeneous group of malignant mesenchymal neoplasms characterized by a strong tendency toward local recurrence and metastatic spreading. Consistently, the immune microenvironment in sarcomas is highly variable. A new class of material with high electron density, hafnium oxide, was designed at the nanoscale to efficiently absorb ionizing radiation […]

2017 – Abstract Conference Immunotherapy Radiotherapy Combinations NYC

Hafnium oxide, an electron-dense material, was designed at the nanoscale to increase the radiation dose deposited from within the cancer cells: “Hot spot” of energy deposit where the nanoparticles are when exposed to radiation therapy (RT). Preclinical studies have demonstrated increase of cancer cells killing in vitro and marked antitumor efficacy in vivo with presence of these nanoparticles […]

2017 – Abstract SITC Conference Maryland – Non Clinical

Hafnium oxide, an electron-dense material, was designed at the nanoscale to increase the radiation dose deposited from within the cancer cells: “Hot spot” of energy deposit where the nanoparticles are when exposed to radiation therapy (RT). Preclinical studies have demonstrated increase of cancer cells killing in vitro and marked antitumor efficacy in vivo with presence of these nanoparticles […]

2017 – AACR Abstract – NBTXR3 combination with cisplatin in vivo and in vitro

Combination of NBTXR3 and cisplatin has been evaluated in vitro and in vivo. No specific toxicity was observed for the cells exposed only to NBTXR3. For the combined treatment, a marked and enhanced cell destruction when compared to the single agent. In vivo, NBTXR3 combined with low dose of cisplatin delayed tumor growth when compared to single agent CDDP in combination with RT. NBTXR3 is intended to be injected in the tumors. Spilling in the circulation may occur during product administration or, as expected, during tumor destruction, leading to steady trapping of NPs in the reticulo-endothelial system (liver and spleen). Clinically, it is unknown whether patients, previously treated with NPs, may show toxic signs when NPs are exposed (activation) to diagnosis imaging (computed tomography(CT)) of the liver.

2017 – AACR Abstract – NBTXR3 anti-tumor efficacy in vivo

NBTXR3 has been evaluated in numerous in vivo models. The antitumor efficacy was systematically enhanced in terms of tumor growth delay for animals treated with NBTXR3 and exposed to radiotherapy when compared to radiotherapy alone. In this abstract the transferability of the treatment with NBTXR3 from one type of cancer to the other is described. NBTXR3 is intended to be injected in the tumors. Spilling in the circulation may occur during product administration or, as expected, during tumor destruction, leading to steady trapping of NPs in the reticulo-endothelial system (liver and spleen). Clinically, it is unknown whether patients, previously treated with NPs, may show toxic signs when NPs are exposed (activation) to diagnosis imaging (computed tomography(CT)) of the liver.

2016 – SITC Abstract – NBTXR3 for in situ cancer vaccination

NBTXR3 exposed to irradiation enhanced cancer cells destruction and immunogenic cell death compared to irradiation alone, suggesting a strong potential for transforming tumor into an effective in situ vaccine. This may contribute to transform “cold” tumor into “hot” tumor and effectively be combined with most of the immunotherapeutic agents across oncology. NBTXR3 is intended to be injected in the tumors. Spilling in the circulation may occur during product administration or, as expected, during tumor destruction, leading to steady trapping of NPs in the reticulo-endothelial system (liver and spleen). Clinically, it is unknown whether patients, previously treated with NPs, may show toxic signs when NPs are exposed (activation) to diagnosis imaging (computed tomography(CT)) of the liver.
