2021 – Results from the phase I dose-escalation study of the radiation enhancer NBTXR3 for the treatment of HCC and liver metastases

Abstracts, Donnée clinique de NBTXR3, Foie, NO-RIGHTS

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). […]

2021 – A new radio-enhancer, PEP503 (NBTXR3), in combination with concurrent chemoradiation in locally advanced or unresectable rectal cancer: The dose-finding part of a phase I/II trial

Abstracts, Donnée clinique de NBTXR3, NO-RIGHTS, Rectum

PEP503 (as known as NBTXR3) is a novel radio-enhancer composed of functionalized hafnium oxide nanoparticles for a higher energy deposit by radiotherapy comparing to radiotherapy alone without it. A prior phase 3 study for soft tissue sarcoma has demonstrated the clinical benefit. […]

2020 – Int J Nanomedicine NBTXR3 Induces Abscopal Effect

In Vitro in Vivo NBTXR3, In Vivo, NO-RIGHTS, Publications

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. […]

2020 – Phase I study of intratumoral NBTXR3 in combination with anti-PD-1 in patients with advanced cancers

Abstracts, Donnée clinique de NBTXR3, Foie, Poumon, Tête & Cou

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). […]

2020 – RT-activated hafnium oxide nanoparticles in cisplatin-ineligible locally advanced HNSCC patients

Abstracts, Donnée clinique de NBTXR3, NO-RIGHTS, Tête & Cou

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 […]

2020 – NANORAY-103: Phase I/II trial of NBTXR3 activated by SBRT in patients with HCC and liver metastases

Abstracts, Donnée clinique de NBTXR3, Foie, NO-RIGHTS

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. […]

2020 – Phase I/II Study Of Radiation Enhancing Hafnium Oxide Nanoparticles NBTXR3 Activated by SBRT in HCC and Liver Metastases Patients

Abstracts, Donnée clinique de NBTXR3, Foie

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. […]

2020 – NBTXR3 radiation enhancing hafnium oxide nanoparticles: RP2D for the treatment of HCC and liver metastases

Abstracts, Donnée clinique de NBTXR3, Foie

NBTXR3, functionalized hafnium oxide nanoparticles, administered by intratumoral injection (ITI) and activated by radiotherapy (RT), such as stereotactic body RT (SBRT), increases energy deposit inside tumor cells and subsequently tumor cell death compared to RT alone, while sparing healthy tissues. This innovative approach, which does not engage liver and renal functions, might benefit patients (pts) with unresectable liver cancers. […]

2020 – NBTXR3 Radiation Enhancing Hafnium Oxide Nanoparticles Activated By Radiotherapy In Cisplatin-Ineligible Patients With Locally Advanced HNSCC: A Phase I Trial

Abstracts, Donnée clinique de NBTXR3, NO-RIGHTS, Tête & Cou

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). […]

2020 – Phase I study of NBTXR3 activated by radiotherapy in patients with advanced cancers treated with an anti-PD-1 therapy

Abstracts, Donnée clinique de NBTXR3, Foie, NO-RIGHTS, 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. […]
