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 – 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 – SITC – NBTXR3 Generates Long Term Immune Memory

Congress Abstracts, In Vitro in Vivo NBTXR3, In Vivo

Although treatment of high-dose (HD) radiation (XRT) and NBTXR3 (R3) on primary tumors in combination with systemic anti-PD1 was able to significantly improve abscopal effect in 344SQR murine metastatic lung cancer, most of the mice eventually expired due to the growth of metastatic tumors. Therefore, we studied the effects of R3 injection into primary tumors plus high-dose radiation on primary tumor and low-dose raditionon metastatic tumor plus dual-agent immunotherapy (IT) of anti-PD1 and anti-CTLA-4 to achive complete control of tumor growth at both the primary and the metastatic tumors in mice. […]

2020 – SITC – TCR Repertoire

Congress Abstracts, In Vitro in Vivo NBTXR3, In Vivo

For decades, radiotherapy (RT) has been a cornerstone of cancer treatment. Currently, approximately 50% of cancer patients will be treated with RT. Beyond the ability of RT to produce free radicals and to generate single and double-strand breaks in DNA, triggering cell death, preclinical and clinical studies have demonstrated that RT can have immunomodulatory effects. For example, RT can stimulate MHC class I expression on cancer cells, induce immunogenic cell death (ICD), and activate expression of various pro- and anti-inflammatory cytokines and adhesion molecules, allowing recruitment and activation of both innate and adaptive immune cells into the tumor. […]

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. […]
