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 – Immunotherapy Workshop

Radiotherapy (RT) has proven its ability to function like an in-situ vaccine, showing potential for successful combination with immunotherapeutic agents. Hafnium oxide nanoparticle (HfO2-NP), undergoing clinical trials for enhancing RT, was designed as high electron density material at the nanoscale. HfO2-NPs are taken up by cancer cells and, when exposed to RT, locally increase the radiation dose deposit, triggering more cancer cells death when compared to RT. We hypothesized that HfO2-NP+RT could trigger an enhanced immune response when compared to RT, both in preclinical and clinical settings.

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.
