2018 – ECHNO 2018 – NBTXR3 for elderly and frail HNSCC patients

Clinical Data NBTXR3, Congress Abstracts, Head & Neck

NBTXR3 administered as a single intratumoral injection and activated by radiotherapy, is currently evaluated in a phase I clinical trial for head and neck cancer. At the 2018 Multidisciplinary Head and Neck Cancers Symposium in Scottsdale Arizona, preliminary results were presented by prof. C. Le Tourneau. […]

2018 – Multidisciplinary H&N – NBTXR3 for Head and Neck Cancer

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

Clinical Data NBTXR3, Congress Abstracts, Head & Neck, Liver, Rectum, STS

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.

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

Clinical Data NBTXR3, Congress Abstracts, Head & Neck

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 – 35th CFS – Hafnium Oxide Nanoparticles: An Emergent Promising Treatment for Solid Tumors

Congress Abstracts, In Vitro, In Vitro in Vivo NBTXR3

Hafnium oxide nanoparticles: an emergent promising treatment for solid tumors To improve tumor response, radiotherapy (RT) has been combined with chemical agents, radiosensitizers and monoclonal antibodies. However, the complexity of these associations in terms of pharmacology, local control, clinical outcome benefits or patient quality of life underlines the need for the development of new therapeutic approaches. […]

2017 – Abstract Conference Immunotherapy Radiotherapy Combinations NYC

Congress Abstracts, In Vitro, In Vitro in Vivo NBTXR3, In Vivo

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 AACR-EORTC-NCI

Congress Abstracts, In Vitro in Vivo NBTXR3, In Vivo

Between 70 to 90% of patient have "cold" tumors, i.e. devoid or poorly infiltrated by immune cells, rendering inoperative their treatment by immune checkpoint inhibitors. To allow these patients to benefit from these therapies, it is fundamental to prime an antitumor immune response. […]

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

Congress Abstracts, In Vitro, In Vitro in Vivo NBTXR3, In Vivo

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

Congress Abstracts, In Vitro in Vivo NBTXR3, 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.
