Congress Abstracts

Congresses are a key element for Nanobiotix to publish scientific data and results. This section lists abstracts that have been published by Nanobiotix over the last decade.

2018 – ASTRO – NBTXR3 Anti-Tumor Immune Response

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 – OncoRad – NBXTR3 in HNSCC and NSCLC with anti-PD1

Recent clinical studies have demonstrated the efficacy of anti-PD-1 in recurrent/metastatic HNSCC and upfront metastatic NSCLC patients. However, most patients with recurrent/metastatic HNSCC demon-strate innate (primary) resistance to checkpoint inhibition and do not respond to initial therapy and only a subset of metastatic HNSCC/NSCLC patients benefits from this treatment. […]

2018 – ASCO – NBTXR3 generates an anti-tumor immune response

The enclosed abstract was presented at the 13th Journées cancéropole Grand Sud-Ouest at Poitiers. The abstract Hafnium oxide nanoparticles as an emergent promising treatment for solid tumors describes how hafnium oxide nanoparticles were designed at the nanoscale in the form of crystalline 50nm-particles to efficiently absorb ionizing radiation and increase the radiation dose deposited – “hot spots” of energy deposit – from within the tumor cells for efficient cell killing.

2019 – ESMO WGI – NBTXR3 in unresectable liver cancers

The treatment of liver cancers is challenging in part due to the presence of underlying liver diseases. In patients unsuitable for surgery, interventional radiation oncology approaches, i.e. minimally invasive image guided therapeutic procedures, offer new treatment opportunities and can achieve good local control. NBTXR3, hafnium oxide nanoparticles, administered via intratumoral injection, increases energy deposit inside tumor cells only when activated by ionizing radiation such as stereotactic body radiotherapy (SBRT) and thus increase tumor cell death compared to radiation alone. […]

2019 – ASCO – NBTXR3 in Liver Cancers

Hafnium oxide nanoparticles, NBTXR3, increase the effect of radiotherapy (RT) by enhancing local energy dose deposit within tumor cells, resulting in increased cell death compared to the same dose of RT alone. NBTXR3 efficacy was demonstrated in a phase II/III study in soft tissue sarcoma (NCT02379845) and is currently evaluated in other solid tumors including liver cancers. The use of this radio enhancer is particularly relevant in liver cancer management, a difficult to treat heterogenous population, due to the presence of underlying liver dysfunction. […]

2019 – ASCO – NBTXR3 induces antitumor immune response

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. […]

2019 – ASCO – Phase I NBTXR3 in elderly/frail HNSCC patients

New therapeutic approaches are needed for elderly or frail head and neck squamous cell carcinoma (HNSCC) patients (pts) ineligible for standard of care treatment. NBTXR3, a crystalline solution of hafnium oxide nanoparticles may represent such an option. Injected intratumorally, NBTXR3 enters tumor cells and yields an increased cell-localized energy deposit upon exposure to radiotherapy (RT), leading to increased tumor cell death compared to the same dose of RT alone. […]

2019 – AHNS – Phase I/II NBTXR3 in combination with anti-PD-1

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. […]

2019 – ESTRO – Randomized NBTXR3 trial in 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.

2019 – ESTRO – NBTXR3 activated by SBRT in liver cancers

Patients with hepatocellular carcinoma (HCC) and liver metastasis (mets) present with a wide range of underlying liver dysfunctions and concomitant malignancies. Stereotactic body radiation therapy (SBRT) is well-tolerated and a valuable alternative for patients who are not eligible for invasive procedures. Yet, like all radiation therapy (RT) techniques, the energy dose deposit to tumor cells is limited by the surrounding healthy tissues. […]
