Data Published in the November 2021 Edition of the International Journal of Radiation Oncology, Biology, Physics (Red Journal)
Paris, France; Cambridge, Massachusetts (USA); September 28, 2021 – NANOBIOTIX (Euronext : NANO –– NASDAQ: NBTX – the ‘‘Company’’), a late-clinical stage biotechnology company pioneering nanophysics-based approaches to expand treatment possibilities for patients with cancer, today announced the publication of preclinical findings with The University of Texas MD Anderson Cancer Center (MD Anderson) in the International Journal of Radiation Oncology, Biology, Physics (Red Journal). These data support the further exploration of potential first-in-class, solid tumor-agnostic, therapeutic combination-agnostic radioenhancer NBTXR3 as a new therapeutic option seeking to induce significant tumor cell death when activated by radiotherapy, prime immune response, and overcome resistance to anti-PD-1.

“Patients across the oncology landscape are in urgent need of innovation that can make a difference,” said Laurent Levy, co-founder and chief executive officer of Nanobiotix. “We are proud to collaborate with MD Anderson as we seek to validate the broadly applicable, local and systemic potential benefits of NBTXR3. The Red Journal provides a critical platform for the advancement of radiation oncology, and we believe this publication represents an important contribution to the academic and medical research communities as we seek to expand treatment possibilities for millions of patients with cancer.”
Immune checkpoint inhibitors (ICIs) such as anti-PD-1 have shown tremendous promise for the treatment of some patients with metastatic tumors. Oncologists have hypothesized the possibility of combining ICIs with radiotherapy (RT) to control the irradiated tumor and turn those tumors into a “self-vaccine” that could improve systemic control of distant metastases as well. To date, however, most patients with cancer have shown resistance to anti-PD-1, limiting the effect of this combination.
This preclinical mouse model study conducted in collaboration between MD Anderson and Nanobiotix hypothesized that NBTXR3 could “reprogram” the tumor microenvironment in local and distant tumors, overcoming resistance to anti-PD-1 when activated by radiotherapy (RT) in mouse models of metastatic lung cancer.
Key Findings on the Triple Combination of NBTXR3 plus Radiotherapy plus Anti-PD-1 in the Mouse Model
This study supports further exploration of the triple combination of NBTXR3 plus RT plus anti-PD-1 as a new therapeutic option for the treatment of both primary and metastatic lung cancer, and the potential of this combination to achieve the promise of transforming irradiated tumors into “self-vaccines.” These results could support significance for the radioenhancer’s clinical application, as the strong activation of an effective immune response in anti-PD-1 resistant tumors may expand treatment possibilities for the majority of patients who do not respond to anti-PD-1 therapy.
