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. […]

2019 CTOS NBTXR3 in STS phase II/III trial

Clinical Data NBTXR3, Congress Abstracts, STS

A subset of locally advanced soft tissue sarcoma (STS) patients achieve significant therapeutic benefit from preoperative radiation therapy (RT) as shown by Pisters JCO 1996 and Yang JCO 2018. However, the impact of RT on pathological response (pR) and R0 resection is limited, highlighting the need for novel multimodal therapies aimed at local control. NBTXR3 (hafnium oxide nanoparticles), injected intratumorally may represent such an option. Otherwise inert, NBTXR3 augments the effective RT dose deposited within tumor cells when activated by ionizing radiation to increase cancer cell death compared to RT alone. […]

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 – ESTRO – Randomized NBTXR3 trial in STS

Clinical Data NBTXR3, Congress Abstracts, STS

Preoperative radiotherapy (RT) is an option for a subset of patients with locally advanced primary or relapsed tumors. Yet, its impact on efficacy in terms of pathological response is limited, highlighting the need for novel multimodal therapies aimed at local control with low toxicity. NBTXR3 is made of hafnium oxide nanoparticles which, injected intratumorally (IT) and activated by ionizing radiation, yield a tumor-localized high energy deposit and increase cell death compared to the same dose of RT alone. […]

2018 – ASTRO – NBTXR3 Anti-Tumor Immune Response

Clinical Data NBTXR3, Congress Abstracts, STS

Soft tissue sarcoma (STS) is a rare type of cancer, which occurs in tissues connecting, supporting and/or surrounding other structures of the body, like muscle, fat, etc. More than 50 subtypes of STS exist, characterized by a strong propensity to local recurrence and metastatic spreading. Consistently, the immune microenvironment in sarcomas is highly variable. A new class of high electron density material, hafnium oxide, was designed at the nanoscale to efficiently absorb ionizing radiation from within the tumor cells and increase the dose deposition into the tumor. […]

2018 – ASTRO – NBTXR3 Exploratory Dosimetric Study

Clinical Data NBTXR3, Congress Abstracts, STS

NBTXR3, injectable hafnium oxide nanoparticles, was designed to increase the energy deposit of the irradiation when activated by radiotherapy for the treatment of solid tumors. It is currently evaluated in a phase II/III clinical trial in soft tissue sarcoma (STS) [NCT02379845] of the extremity and trunk wall, to compare its efficacy when intratumorally injected and activated by radiotherapy versus radiotherapy alone. […]

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. […]

2018 – ESMO – Phase II/III NBTXR3 in STS

Clinical Data NBTXR3, Congress Abstracts, STS

NBTXR3 is a first-in-class Hafnium-Oxide nanoparticle intratumorally (IT) injected. When activated by radiotherapy (RT), it allows for a higher energy deposit than RT alone, yielding an increased tumoral cell death. A phase I study in soft tissue sarcoma (STS) showed that a single NBTXR3 IT injection at 10% of the baseline tumor volume with preoperative RT was technically feasible with manageable toxicity and clinical activity was observed.
