2020 – Int J Nanomedicine NBTXR3 Induces Abscopal Effect

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. […]

2018 – ASTRO – NBTXR3 Anti-Tumor Immune Response

Soft tissue sarcoma (STS) is a rare type of cancer, which occurs in tissues connecting, supporting and/or surrounding other structures of the body, like muscle, fat, etc. More than 50 subtypes of STS exist, characterized by a strong propensity to local recurrence and metastatic spreading. Consistently, the immune microenvironment in sarcomas is highly variable. A new class of high electron density material, hafnium oxide, was designed at the nanoscale to efficiently absorb ionizing radiation from within the tumor cells and increase the dose deposition into the tumor.

2018 – ASCO – NBTXR3 generates an anti-tumor immune response

The enclosed abstract was presented at the 13th Journées cancéropole Grand Sud-Ouest at Poitiers. The abstract Hafnium oxide nanoparticles as an emergent promising treatment for solid tumors describes how hafnium oxide nanoparticles were designed at the nanoscale in the form of crystalline 50nm-particles to efficiently absorb ionizing radiation and increase the radiation dose deposited – “hot spots” of energy deposit – from within the tumor cells for efficient cell killing.

2020 – ASCO – NBTXR3 With Anti PD1 Therapy

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 – NBTXR3 Dose Expansion for Locally Advanced HNSCC

The standard of care non-surgical approach for locally advanced head and neck squamous cell carcinoma (LA HNSCC) patients (pts) is concurrent chemoradiation with high dose cisplatin or cetuximab in case of contra-indication. Older age is a contra-indication to cisplatin, and cetuximab might not improve survival in older pts. It is therefore urgently needed to develop new treatment options for elderly pts with LA HNSCC. NBTXR3 are hafnium oxide nanoparticles that can enhance the efficacy of radiotherapy (RT) by increasing locally the deposited dose. […]

2020 – MHNCS – NBTXR3 for locally advanced HNSCC

Elderly and/or frail patients (pts) with head and neck squamous cell carcinoma (HSNCC) remain a challenging to manage and neglected population regarding clinical trials and data generation to support treatment choices. Despite representing 20% of the HNSCC population no consensus exists on what is the optimal treatment for these pts with locally advanced (LA) disease, vulnerable to treatment-induced toxicities with the current standard of care.

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

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

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

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. […]
