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. […]

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 – 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 – 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

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

Clinical Data NBTXR3, Congress Abstracts, Head & Neck

2019 – Phase I/II trial of NBTXR3 activated by SBRT in patients with hepatocellular carcinoma or liver metastasis

Clinical Data NBTXR3, Congress Abstracts, Liver

Treatment of hepatocellular carcinoma (HCC) and liver metastasis (mets) is challenging due to presence of underlying disease, e.g. cirrhosis. Stereotactic body radiation therapy (SBRT) is a well-tolerated alternative for inoperable patients (pts), yet maximal dose to the tumor is limited by potential toxicity to surrounding healthy tissues. […]

2019 – NBTXR3 Activated By Radiotherapy Generates an Anti-Tumor Immune Response

Congress 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 – RSNA – Treatment of locally advanced HNSCC by NBTXR3

Clinical Data NBTXR3, Congress Abstracts, Head & Neck

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 – SIOG – NBTXR3 for the treatment of elderly/frail HNSCC patients

Clinical Data NBTXR3, Congress Abstracts, Head & Neck

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. […]
