2020 – Phase I trial of hafnium oxide nanoparticles activated by radiotherapy in cisplatin-ineligible locally advanced HNSCC patients

Clinical Data NBTXR3, Congress Abstracts, Head & Neck, NO-RIGHTS

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. […]

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

Clinical Data NBTXR3, Congress Abstracts, Head & Neck, NO-RIGHTS

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 – Treatment of hepatocellular carcinoma and liver metastases with hafnium oxide nanoparticles activated by SBRT: a phase I/II trial

Clinical Data NBTXR3, Congress Abstracts, Liver

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). […]

2020 – ESTRO – NBTXR3 for the Treatment of Advanced Liver Cancers

Clinical Data NBTXR3, Congress Abstracts, Liver

The use of stereotactic body radiotherapy (SBRT) for the local control of unresectable hepatocellular carcinoma (HCC) or liver metastases (mets) is well tolerated but limited by the need to preserve liver function. Increasing energy deposit within the tumor without increasing toxicity in healthy tissues remains a major challenge in radiation oncology. NBTXR3 (hafnium oxide nanoparticles), a first-in-class radioenhancer when activated by RT augments energy dose deposit within tumor cells, increasing tumor cell death compared to RT alone, while sparing healthy tissues. […]

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 – ESTRO – NBTXR3 for the Treatment of Locally Advanced HNSCC

Clinical Data NBTXR3, Congress Abstracts, Head & Neck

Elderly and frail patients (pts) with head and neck squamous cell carcinoma (HSNCC) remain a challenging population to manage due to the lack of evidence-based recommendations. Despite representing approximately 20% of the HNSCC population no consensus exists on the optimal treatment for these pts with locally advanced (LA) disease, vulnerable to current standard of care treatment-induced toxicities. New approaches are thus needed to improve clinical outcomes without adding toxicity. NBTXR3 hafnium oxide nanoparticles injected intratumorally may represent such an option. […]

2020 – ASTRO – NBTXR3 in HNSCC

Clinical Data NBTXR3, Congress Abstracts

Concurrent chemoradiation (CRT) with high dose cisplatin or cetuximab in case of contra-indication to cisplatin is the standard of care non-surgical approach for patients (pts) with locally advanced head and neck squamous cell carcinoma (LA HNSCC). Older age is a contra-indication to cisplatin and survival in older pts might not improve with cetuximab. The development of new treatment options for elderly pts with LA HNSCC is therefore urgently needed. […]

2020 – ASTRO – NBTXR3 in Advanced Liver Cancers

Clinical Data NBTXR3, Congress Abstracts, Liver

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

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. […]
