2020 – Phase I study of NBTXR3 activated by radiotherapy in patients with advanced cancers treated with an anti-PD-1 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 – Hafnium oxide nanoparticles (NBTXR3) activated by radiotherapy for the treatment of frail and/or elderly patients with locally advanced HNSCC: a phase I/II study

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

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

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 – A Phase I Study of NBTXR3 Activated by Radiotherapy for Patients with Advanced Cancers Treated With an Anti-PD-1 Therapy

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. […]

2019 – NBTXR3 for the treatment of locally advanced HNSCC in frail and/or elderly patients: a phase I/II study

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. […]

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

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. […]

2017 – Abstract – 13th Journées cancéropole GSO – HfO2 nanoparticles in solid tumors

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.
