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 generates an anti tumor immune response

Abstracts, In Vitro in Vivo NBTXR3, In Vivo

Hafnium oxide nanoparticles (NBTXR3) activated by radiotherapy (RT) increase radiation dose deposit within cancer cells compared to RT alone. Currently 7 clinical trials are underway to evaluate NBTXR3+RT. To date, no dose limiting toxicities (DLTs) have been observed. Given that RT can prime an anti-tumor immune response we hypothesized that this response could be enhanced by NBTXR3+RT in both animals and humans. […]

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 – NBTXR3 induces antitumor immune response

Abstracts, In Vitro in Vivo NBTXR3, In Vivo

Radiotherapy (RT) can prime an anti-tumor immune response. Unfortunately, this response rarely generates total tumor destruction and abscopal effect. When activated by RT, intratumorally (IT) administered hafnium oxide nanoparticles (NBTXR3) locally increase radiation dose deposit and tumor cell death compared to RT alone. We hypothesized that NBTXR3 + RT could enhance the anti-tumor immune response, both in mice and humans. […]

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.
