2020 – SITC – NBTXR3 Generates Long Term Immune Memory

Congress Abstracts, In Vitro in Vivo NBTXR3, In Vivo

Although treatment of high-dose (HD) radiation (XRT) and NBTXR3 (R3) on primary tumors in combination with systemic anti-PD1 was able to significantly improve abscopal effect in 344SQR murine metastatic lung cancer, most of the mice eventually expired due to the growth of metastatic tumors. Therefore, we studied the effects of R3 injection into primary tumors plus high-dose radiation on primary tumor and low-dose raditionon metastatic tumor plus dual-agent immunotherapy (IT) of anti-PD1 and anti-CTLA-4 to achive complete control of tumor growth at both the primary and the metastatic tumors in mice.

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

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

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 – SITC – NBTXR3 From Bench to Bedside

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

Despite recent advances, resistance to immune checkpoint inhibitors (ICI), observed in over 80% of treated patients, is currently the main challenge immuno-oncology is facing. Intense efforts are being made to identify combination therapies that could improve ICI response rates. Administered intratumorally, NBTXR3 enhances the energy dose deposited by ionizing radiation within tumor cells, increasing the anti-tumor efficacy of radiation therapy (XRT) without adding toxicity to surrounding tissues. […]

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

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

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 – ASCO – NBTXR3 With Anti PD1 Therapy

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

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. […]

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

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

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 – 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. […]
