2019 – RSNA – Treatment of locally advanced HNSCC by NBTXR3

Abstracts, Donnée clinique de NBTXR3, Tête & Cou

Elderly head and neck squamous cell carcinoma (HSNCC) patients (pts) ineligible for standard of care treatment require new therapeutic approaches. NBTXR3, hafnium oxide nanoparticles, may represent such an option. NBTXR3 is activated by radiotherapy, enhancing its effects, leading to physical destruction of cancer cells. A Phase I/II trial [NCT01946867] is underway to evaluate NBTXR3 in elderly (≥70 years) or frail pts with HNSCC of the oral cavity and oropharynx ineligible for cisplatin or intolerant to cetuximab.

2019 – SIOG – NBTXR3 for the treatment of elderly/frail HNSCC patients

Abstracts, Donnée clinique de NBTXR3, Tête & Cou

New therapeutic approaches are needed for elderly or frail head and neck squamous cell carcinoma (HNSCC) patients (pts) ineligible for standard of care. NBTXR3, hafnium oxide nanoparticles injected intratumorally, may represent an option. Otherwise inert, NBTXR3 augments the radiation therapy (RT) dose within tumor cells when activated by RT, increasing tumor cell death compared to RT alone. […]

2019 CTOS NBTXR3 in STS phase II/III trial

Abstracts, Donnée clinique de NBTXR3, STM

A subset of locally advanced soft tissue sarcoma (STS) patients achieve significant therapeutic benefit from preoperative radiation therapy (RT) as shown by Pisters JCO 1996 and Yang JCO 2018. However, the impact of RT on pathological response (pR) and R0 resection is limited, highlighting the need for novel multimodal therapies aimed at local control. NBTXR3 (hafnium oxide nanoparticles), injected intratumorally may represent such an option. Otherwise inert, NBTXR3 augments the effective RT dose deposited within tumor cells when activated by ionizing radiation to increase cancer cell death compared to RT alone. […]

2019 – ESMO – NBTXR3 activated by SBRT in liver cancers

Abstracts, Donnée clinique de NBTXR3, Foie

Treatment of hepatocellular carcinoma (HCC) and liver metastasis (mets) is challenging due to presence of underlying disease, e.g. cirrhosis. Stereotactic body radiation therapy (SBRT) is a well-tolerated alternative for inoperable patients (pts), yet maximal dose to the tumor is limited by potential toxicity to surrounding healthy tissues. Otherwise inert, NBTXR3 (hafnium oxide nanoparticles) when acti- vated by ionizing radiation (RT) augments dose deposit within tumor cells, increasing tumor cell death compared to RT alone. […]

2019 – ASTRO – NBTXR3 for the treatment liver cancers

Abstracts, Donnée clinique de NBTXR3, Foie

The medical community faces important challenges to treat liver cancer because of underlying disease. Reduction of healthy tissue irradiation while at the same time increasing energy dose deposit within tumor cells still constitutes a challenge in radiation oncology. NBTXR3, hafnium oxide nanoparticles, increase energy deposit inside tumor cells only when activated by ionizing radiation such as stereotactic body radiotherapy (SBRT) and thus increase tumor cell death compared to radiation alone. […]

2019 – ASTRO – NBTXR3 for the treatment of solid tumors

Abstracts, Donnée clinique de NBTXR3, Foie, Rectum, STM, Tête & Cou

Local interventional treatments of cancers include interventional radiology and radiotherapy (RT). NBTXR3, hafnium oxide nanoparticles, is deeply associated to both. Given as a single local administration it increases energy dose deposit inside tumor cells only when activated by ionizing radiation. Various interventional treatments have been used to treat cancers such as liver, lung, bone. Because entirely new therapies such as NBTXR3 are being introduced, implementation of interventional approaches is continuously growing. […]

2019 – ESMO WGI – NBTXR3 in unresectable liver cancers

Abstracts, Donnée clinique de NBTXR3, Foie

The treatment of liver cancers is challenging in part due to the presence of underlying liver diseases. In patients unsuitable for surgery, interventional radiation oncology approaches, i.e. minimally invasive image guided therapeutic procedures, offer new treatment opportunities and can achieve good local control. NBTXR3, hafnium oxide nanoparticles, administered via intratumoral injection, increases energy deposit inside tumor cells only when activated by ionizing radiation such as stereotactic body radiotherapy (SBRT) and thus increase tumor cell death compared to radiation alone.

2019 – ASCO – NBTXR3 in Liver Cancers

Abstracts, Donnée clinique de NBTXR3, Foie

Hafnium oxide nanoparticles, NBTXR3, increase the effect of radiotherapy (RT) by enhancing local energy dose deposit within tumor cells, resulting in increased cell death compared to the same dose of RT alone. NBTXR3 efficacy was demonstrated in a phase II/III study in soft tissue sarcoma (NCT02379845) and is currently evaluated in other solid tumors including liver cancers. The use of this radio enhancer is particularly relevant in liver cancer management, a difficult to treat heterogenous population, due to the presence of underlying liver dysfunction. […]

2019 – ASCO – Phase I NBTXR3 in elderly/frail HNSCC patients

Abstracts, Donnée clinique de NBTXR3, Tête & Cou

New therapeutic approaches are needed for elderly or frail head and neck squamous cell carcinoma (HNSCC) patients (pts) ineligible for standard of care treatment. NBTXR3, a crystalline solution of hafnium oxide nanoparticles may represent such an option. Injected intratumorally, NBTXR3 enters tumor cells and yields an increased cell-localized energy deposit upon exposure to radiotherapy (RT), leading to increased tumor cell death compared to the same dose of RT alone.

2019 – AHNS – Phase I/II NBTXR3 in combination with anti-PD-1

Abstracts, Donnée clinique de NBTXR3, Foie, Poumon, Tête & Cou

Preoperative radiotherapy (RT) is an option for a subset of patients with locally advanced primary or relapsed tumors. Yet, its impact on efficacy in terms of pathological response is limited, highlighting the need for novel multimodal therapies aimed at local control with low toxicity. NBTXR3 is made of hafnium oxide nanoparticles which, injected intratumorally (IT) and activated by ionizing radiation, yield a tumor-localized high energy deposit and increase cell death compared to the same dose of RT alone.
