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

Clinical Data NBTXR3, Congress Abstracts, Liver, 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

Clinical Data NBTXR3, Congress Abstracts, 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. […]

2021 – Eur J Cancer – NBTXR3 Phase I in HNSCC

Clinical Data NBTXR3, Head & Neck, NO-RIGHTS, Publications

This phase I study assessed the safety of first-in-class radioenhancer nanoparticles, NBTXR3, in elderly or frail patients with locally advanced head and neck squamous cell carcinoma (HNSCC), ineligible for chemoradiation. This is an observational, retrospective, international, study of adult patients with primary non-metastatic STS of the extremities and trunk wall, any grade, diagnosed between 2008 and 2012, treated with at least neoadjuvant treatment and surgical resection and observed for a minimum of 3 years after diagnosis. […]

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

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). […]

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

Clinical Data NBTXR3, Congress Abstracts, Liver, 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 – RT-activated hafnium oxide nanoparticles in cisplatin-ineligible locally advanced HNSCC patients

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

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 – NBTXR3 Radiation Enhancing Hafnium Oxide Nanoparticles Activated By Radiotherapy In Combination With Anti-PD-1 Therapy: A Phase I Study

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. […]

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

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. […]

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

Clinical Data NBTXR3, Congress Abstracts, Liver

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. […]
