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 – 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. […]

2019 – ASCO-SITC – NBTXR3 with anti-PD-1 in advanced HNSCC or NSCLC

Despite proven efficacy, a limited number of patients (pts) with recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) or metastatic non-small cell lung cancer (NSCLC) benefit from anti-PD-1 treatment. Indeed, most pts do not respond to initial therapy due to intrinsic re-sistance to checkpoint inhibition. There is thus an important unmet medical need for a curative treatment in these pts and converting the local immune microenvironment to a “hot” phenotype may help to overcome therapeutic resistance. […]

2019 – ICHNO – Phase I/II NBTXR3 in HNSCC

Hafnium oxide nanoparticles, NBTXR3, were developed to augment tumor-localized high energy deposit once activated by ionizing radiation such as Intensity Modulated Radiation Therapy (IMRT) and thus to increase tumor cell death compared to the same dose of radiation. NBTXR3 is characterized by a single intratumoral (IT) administration and fits into standard radiotherapy schedule with no change in patient’s care pathway, treatment protocol or equipment. […]
