2021 – Long-term results from the phase II/III Act.In.Sarc trial evaluating NBTXR3 in locally advanced STS

Clinical Data NBTXR3, Congress Abstracts, NO-RIGHTS, STS

NBTXR3, a novel radioenhancer activated by radiotherapy (RT) demonstrated superior efficacy, as preoperative treatment in patients with locally advanced soft tissue sarcoma (LA STS) compared to RT alone. […]

2021 – NBTXR3 activated by radiotherapy in cisplatin-ineligible locally advanced HNSCC patients

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

Concurrent radiotherapy (RT) with high-dose cisplatin, or cetuximab in case of intolerance to cisplatin, are the non-surgical standard treatment for locally advanced head and neck squamous cell carcinoma (LA HNSCC). However, elderly patients, patients with poor performance status, comorbidities, and/or intolerance may not benefit from these treatments […]

2021 – Long-term evaluation of the novel radioenhancer NBTXR3 plus radiotherapy in patients with locally advanced soft tissue sarcoma treated in the phase II/III Act.In.Sarc trial

Clinical Data NBTXR3, Congress Abstracts, NO-RIGHTS, STS

NBTXR3, a novel radioenhancer activated by radiotherapy (RT) demonstrated superior efficacy, as preoperative treatment, in patients with locally advanced soft tissue sarcoma (LA STS), compared to RT alone. […]

2021 – Radiation enhancing NBTXR3 for the treatment of cisplatin-ineligible locally advanced HNSCC patients

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

The non-surgical standard of care (SOC) for the treatment of locally advanced head and neck squamous cell carcinoma(LA HNSCC) is concurrent chemoradiation with high dose cisplatin or cetuximab in case of contra-indication to cisplatin. However elderly patients, and those with poor performance status, comorbidities, and/or intolerance, may not benefit from these SOC treatments and represent a high unmet need. […]

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). […]

2020 – NBTXR3 nanoparticle with immunoradiation improves survival and generates long-term anti-tumor memory in an anti-PD1 resistant murine lung cancer model

Congress Abstracts, In Vitro in Vivo NBTXR3, In Vivo

Although treatment with high-dose (HD) radiation (XRT) and NBTXR3 on primary tumors in combination with systemic anti-PD1 was able to significantly improve abscopal effect in 344SQR murine metastatic lung cancer model, most of the mice eventually died due to the growth of secondary tumors. […]

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. […]

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. […]

2018 – ASTRO – NBTXR3 in solid tumors

Clinical Data NBTXR3, Congress Abstracts, Head & Neck, Liver, Rectum, STS

To improve radiotherapy (RT) in terms of tumor response and to reduce irradiation of healthy tissues, innovative therapeutic approaches are needed. In response, NBTXR3, injectable hafnium oxide nanoparticles, was developed for the treatment of solid tumors. Once injected intratumorally, NBTXR3 can deposit high energy within tumors only when activated by an ionizing radiation source, like current standard RTs. […]

2017 – Immunotherapy Workshop

Congress Abstracts, In Vitro in Vivo NBTXR3, In Vivo

Radiotherapy (RT) has proven its ability to function like an in-situ vaccine, showing potential for successful combination with immunotherapeutic agents. Hafnium oxide nanoparticle (HfO2-NP), undergoing clinical trials for enhancing RT, was designed as high electron density material at the nanoscale. HfO2-NPs are taken up by cancer cells and, when exposed to RT, locally increase the radiation dose deposit, triggering more cancer cells death when compared to RT. We hypothesized that HfO2-NP+RT could trigger an enhanced immune response when compared to RT, both in preclinical and clinical settings.
