2022 – NBTXR3, a first-in-class radioenhancer for pancreatic ductal adenocarcinoma

Clinical Data NBTXR3, NO-RIGHTS, Pancreas, Publications

Pancreatic ductal adenocarcinoma (PDAC) remains one of the leading causes of cancer-related deaths in the world. For patients with PDAC who are not eligible for surgery, radiation therapy improves local disease control, yet safely delivering therapeutic doses of radiation remains challenging due to off-target toxicities in surrounding normal tissues. NBTXR3, a novel radioenhancer composed of functionalized hafnium oxide crystalline nanoparticles […]

2022 – Nanoparticle therapy for head and neck cancers

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

Nanoparticles are spherical nanoscale objects that have application in cancer therapies. Nanoparticles have diverse and often composite structure composition to ensure their function, increase their bioavailability in tumor tissues, and decrease off-target effects, sometimes by means of activating internal or external stimuli. Hafnium oxide nanoparticles are being tested in phase I to III trials for radiotherapy enhancement. […]

2021 – A radioenhancing nanoparticle mediated immunoradiation improves survival and generates long-term antitumor immune memory in an anti-PD1-resistant murine lung cancer model

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

Combining radiotherapy with PD1 blockade has had impressive antitumor effects in preclinical models of metastatic lung cancer, although anti-PD1 resistance remains problematic. Here, we report results from a triple-combination therapy in which NBTXR3, a clinically approved nanoparticle radioenhancer, is combined with high-dose radiation (HDXRT) to a primary tumor […]

2021 – Radiation Therapy Enhanced by NBTXR3 Nanoparticles Overcomes Anti-PD1 Resistance and Evokes Abscopal Effects

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

Radiation combined with PD1 blockade offers significant treatment benefits in several tumor types; however, anti-PD1 resistance precludes such benefits in many cases. Here we attempted to overcome anti-PD1 resistance by combining localized radiation with a radioenhancing nanoparticle (NBTXR3) and systemic anti-PD1 treatment to achieve abscopal effects in an anti-PD1–resistant mouse model of lung cancer. […]

2021 – NBTXR3 Radiotherapy-Activated Functionalized Hafnium Oxide Nanoparticles Show Efficient Antitumor Effects Across a Large Panel of Human Cancer Models

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

The side effects of radiotherapy induced on healthy tissue limit its use. To overcome this issue and fully exploit the potential of radiotherapy to treat cancers, the first-in-class radioenhancer NBTXR3 (functionalized hafnium oxide nanoparticles) has been designed to amplify the effects of radiotherapy. […]

2021 – Eur J Surg Oncol – STS Retrospective Study

Clinical Data NBTXR3, NO-RIGHTS, Publications, STS

Locally advanced soft tissue sarcoma (STS) management may include neoadjuvant or adjuvant treatment by radiotherapy (RT), chemotherapy (CT) or chemoradiotherapy (CRT) followed by wide surgical excision. While pathological complete response (pCR) to preoperative treatment is prognostic for survival in osteosarcomas, its significance for STS is unclear. We aimed to evaluate the prognostic significance of pCR to pre-operative treatment on 3-year disease-free survival (3y-DFS) in STS patients. […]

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 – Review of Clinical Application of Radiation Enhancing Nanoparticles

Miscellaneous, NO-RIGHTS, Publications

The two main NP used in clinical trials were hafnium oxide and gadolinium involving a total of 229 patients. Hafnium oxide NP were used in three phase 1/2 trials on sarcoma, head and neck squamous cell carcinoma or liver cancer and one phase 2/3 trial. There are six ongoing phase 1/2 clinical trials to evaluate the combination of gadolinium-based NP and RT for the treatment of brain metastases and cervical cancer. […]

2020 – Endobronchial ultrasound-guided injection of NBTXR3 radio-enhancing nanoparticles into mediastinal and hilar lymph nodes: a swine model to evaluate feasibility, injection technique, safety, nanoparticle retention and dispersion

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

Loco-regionally advanced lung cancer is typically treated with a combination of chemotherapy and radiation therapy, but overall survival and local control remain poor. Radio-enhancing nanoparticles such as NBTXR3 activated by radiotherapy results in increased cell death and potentially an anti-tumor immune response. The goal of this study was to assess the feasibility and safety of endobronchial ultrasound (EBUS)-guided injection of NBTXR3 into mediastinal and hilar lymph nodes (LN), as well as assess nanoparticle retention in the LN post-injection. […]

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. […]
