2019 – RSNA – Treatment of locally advanced HNSCC by NBTXR3

Clinical Data NBTXR3, Congress Abstracts, Head & Neck

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 – RSNA – Anti-tumor immune response induced by NBTXR3

Congress Abstracts, In Vitro in Vivo NBTXR3, In Vivo

First in class hafnium oxide nanoparticles (NBTXR3) activated by radiotherapy (RT) increase radiation dose deposit within cancer cells compared to RT alone. 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 – SIOG – NBTXR3 for the treatment of elderly/frail HNSCC patients

Clinical Data NBTXR3, Congress Abstracts, Head & Neck

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 – ASTRO – NBTXR3 generates an anti tumor immune response

Congress 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

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

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 – ASCO – NBTXR3 induces antitumor immune response

Congress 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

Clinical Data NBTXR3, Congress Abstracts, Head & Neck

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

Clinical Data NBTXR3, Congress Abstracts, Head & Neck, Liver, Lung

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. […]

2019 – ASCO-SITC – NBTXR3 with anti-PD-1 in advanced HNSCC or NSCLC

Clinical Data NBTXR3, Congress Abstracts, Head & Neck, Lung

Despite proven efficacy, a limited number of patients (pts) with recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) or metastatic non-small cell lung cancer (NSCLC) benefit from anti-PD-1 treatment. Indeed, most pts do not respond to initial therapy due to intrinsic re-sistance to checkpoint inhibition. There is thus an important unmet medical need for a curative treatment in these pts and converting the local immune microenvironment to a “hot” phenotype may help to overcome therapeutic resistance. […]

2019 – ICHNO – Phase I/II NBTXR3 in HNSCC

Clinical Data NBTXR3, Congress Abstracts, Head & Neck

Hafnium oxide nanoparticles, NBTXR3, were developed to augment tumor-localized high energy deposit once activated by ionizing radiation such as Intensity Modulated Radiation Therapy (IMRT) and thus to increase tumor cell death compared to the same dose of radiation. NBTXR3 is characterized by a single intratumoral (IT) administration and fits into standard radiotherapy schedule with no change in patient’s care pathway, treatment protocol or equipment. […]
