2021 – Radiotherapy-activated NBTXR3 nanoparticles Increase CD8+ T cell infiltration and diversity in tumors, and modulate the immunopeptidome of cancer cells

Congress Abstracts, In Vitro in Vivo NBTXR3, In Vivo

When exposed to radiotherapy (RT), NBTXR3 nanoparticles increase radiation dose deposition from within the cancer cells. NBTXR3 is intended for a single intratumor injection. Results from a phase II/III clinical trial in patients with locally advanced Soft Tissue Sarcoma demonstrated significant superiority and clinical benefits of NBTXR3 activated by RT compared to RT alone […]

2021 – Study of Novel Radioenhancer NBTXR3 Plus Radiotherapy in Patients With Locally Advanced Soft Tissue Sarcoma: Results of the Long-Term Evaluation in the Phase II/III Act.In.Sarc Trial

Clinical Data NBTXR3, Congress Abstracts, 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 – Overcoming Resistance to Anti-PD-1 With Tumor Agnostic NBTXR3: From Bench to Bedside

Congress Abstracts, In Vitro in Vivo NBTXR3, In Vivo

Immune checkpoint inhibitors (ICI) can improve outcomes in patients who respond to treatment, however most patients exhibit resistance. Overcoming this resistance is the main challenge in immune-oncology and recent studies suggest radiotherapy (RT) may improve ICI response rates. NBTXR3, composed of functionalized hafnium oxide nanoparticles, is injected intratumorally and activated by RT. […]

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

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 – 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. […]

2019 – RSNA – Anti-tumor immune response induced by NBTXR3

Congress Abstracts, In Vitro in Vivo NBTXR3, In Vivo

First in class hafnium oxide nanoparticles (NBTXR3) activated by radiotherapy (RT) increase radiation dose deposit within cancer cells compared to RT alone. 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 – ASTRO – NBTXR3 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 – ASTRO – NBTXR3 for the treatment of solid tumors

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

Local interventional treatments of cancers include interventional radiology and radiotherapy (RT). NBTXR3, hafnium oxide nanoparticles, is deeply associated to both. Given as a single local administration it increases energy dose deposit inside tumor cells only when activated by ionizing radiation. Various interventional treatments have been used to treat cancers such as liver, lung, bone. Because entirely new therapies such as NBTXR3 are being introduced, implementation of interventional approaches is continuously growing. […]

2019 – ASCO – NBTXR3 induces antitumor immune response

Congress Abstracts, In Vitro in Vivo NBTXR3, In Vivo

Radiotherapy (RT) can prime an anti-tumor immune response. Unfortunately, this response rarely generates total tumor destruction and abscopal effect. When activated by RT, intratumorally (IT) administered hafnium oxide nanoparticles (NBTXR3) locally increase radiation dose deposit and tumor cell death compared to RT alone. We hypothesized that NBTXR3 + RT could enhance the anti-tumor immune response, both in mice and humans. […]
