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 – Phase I study of hafnium oxide nanoparticles activated by Intensity Modulated Radiation Therapy (IMRT) as a new therapeutic option for elderly or frail HNSCC patients

Abstracts, Donnée clinique de NBTXR3, NO-RIGHTS, 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 – NBTXR3 Activated By Radiotherapy 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 – 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.

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. […]
