2020 – Int J Nanomedicine NBTXR3 Induces Abscopal Effect

In Vitro in Vivo NBTXR3, In Vivo, NO-RIGHTS, Publications

Despite tremendous results achieved by immune checkpoint inhibitors, most patients are not responders, mainly because of the lack of a pre-existing anti-tumor immune response. Thus, solutions to efficiently prime this immune response are currently under intensive investigations. Radiotherapy elicits cancer cell death, generating an antitumor-specific T cell response, turning tumors in personalized in situ vaccines, with potentially systemic effects (abscopal effect). Nonetheless, clinical evidence of sustained anti-tumor immunity as abscopal effect are rare. […]

2020 – SITC – NBTXR3 with Anti-PD-1 Therapy

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

Cancer immunotherapies have shown promising clinical outcomes; however, the majority of patients are non-responders or will develop resistance during the course of treatment. One of the current challenges is to increase the response rate to immune checkpoint inhibitors (ICIs). Combining immunotherapy with radiation therapy (RT) is emerging as a valuable strategy to prime the immune response. However, RT dose and ultimate efficacy are limited by toxicity related to exposure of healthy tissues. […]

2020 – ASTRO – NBTXR3 in Advanced Liver Cancers

Abstracts, Donnée clinique de NBTXR3, Foie

Stereotactic body radiotherapy (SBRT) is a well-tolerated and valuable alternative for patients with unresectable hepatocellular carcinoma (HCC) or liver metastases (mets) who are not eligible for standard treatment such as surgery, local ablation or chemoembolization. Yet, the energy dose delivered to the tumor is limited due to potential toxicity to healthy tissues and the need to preserve liver function. […]

2020 – ASTRO – NBTXR3 in Combination with Anti-PD-1

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

Immune checkpoint inhibitors (ICIs) are being increasingly used to improve patient outcomes across different cancer types. However, the response rate to ICIs remains low (~15%), indicating the need for novel strategies to improve treatment outcome. Emerging evidence suggests that radiation therapy (RT) could potentially enhance the antitumor response and provide synergy with ICIs. RT dose and ultimate efficacy are however limited by toxicity related to exposure of healthy tissues. […]

2020 – ESMO – NBTXR3 in HCC and Liver Metastases

Abstracts, Donnée clinique de NBTXR3, Foie

NBTXR3, functionalized hafnium oxide nanoparticles, administered by intratumoral injection (ITI) and activated by radiotherapy (RT), such as stereotactic body RT (SBRT), increases energy deposit inside tumor cells and subsequently tumor cell death compared to RT alone, while sparing healthy tissues. This innovative approach, which does not engage liver and renal functions, might benefit patients (pts) with unresectable liver cancers. […]

2020 – ASCO – NBTXR3 With Anti PD1 Therapy

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

Despite the past decade of transformative advances in immuno-oncology, the response rate to checkpoint inhibitors (ICIs) remains low (~15%). There is significant interest in developing strategies to overcome resistance to these treatments, thus increasing response rate. Emerging evidence suggests that radiation therapy (RT) could potentially augment the antitumor response to ICIs through synergic effect. […]

2020 – ASCO-SITC – NBTXR3 with anti-PD-1 therapy

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

Most cancer patients present resistance to immune therapy; only approximately 15% of patients respond to immune checkpoint inhibitors (ICI). Strategies able to increase ICI response are thus of great interest. Radiotherapy (RT), by acting as an immunomodulator is a good candidate to increase the proportion of ICI responders. However, RT dose and ultimate efficacy are limited by potential toxicity to healthy tissues. NBTXR3, a first in class radioenhancer administered by intratumoral injection, has been designed at the nanoscale to increase RT energy dose deposition within the tumor. […]

2020 – ASCO GI – Treatment of liver cancers with NBTXR3

Abstracts, Donnée clinique de NBTXR3, Foie

Treatment of unresectable liver cancer or liver metastases (mets) by stereotactic body radiotherapy is well tolerated but limited by the need to preserve liver function. Increasing energy deposition in the tumor while at the same time maintaining the dose in healthy tissue remains a major challenge in radiation oncology that could be achieved by NBTXR3 (hafnium oxide nanoparticles) when activated by radiotherapy (RT). NBTXR3 augments energy dose deposit within tumor cells, increasing tumor cell death compared to RT alone, while sparing healthy tissues. […]

2019 – ESMO IO – NBTXR3 with anti-PD-1

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

The majority of cancer patients are resistant to immune therapy; only around 15% respond to immune checkpoint inhibitors (ICI). Thus, strategies able to increase ICI response are of great interest. Recent work suggests radiotherapy (RT) can act as an immunomodulator to increase the proportion of ICI responders and improve clinical outcomes. However, RT dose and ultimate efficacy are limited by toxicity related to exposure of healthy tissues. […]

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.
