About NBTXR3
NBTXR3 is a first-in-class product designed to destroy, when activated by radiotherapy:
• tumors through physical cell death
• metastasis due to immunogenic cell death leading to activation of the immune system
NBTXR3 has a high degree of biocompatibility, requires one single administration before the whole radiotherapy treatment and Nanobiotix believes has the ability to fit into current worldwide standards of radiation care.
Nanobiotix’s broad clinical program includes 10 patient population evaluated in 7 clinical trials.
In June 2018, Nanobiotix established human proof of concept for this first-in-class product in its Soft Tissue Sarcoma (STS) Phase III clinical trial.

NBTXR3 is actively being evaluated in head and neck cancer with locally advanced squamous cell carcinoma of the oral cavity or oropharynx in elderly and frail patients that are unable to receive chemotherapy or cetuximab and have very limited therapeutic options. Promising results have been observed from the ongoing Phase I/II trial regarding the local control of the tumors.

Nanobiotix is running an Immuno-Oncology development program. In the United States, Nanobiotix has received approval from the U.S. Food and Drug Administration (FDA) to launch a clinical study of NBTXR3 activated by radiotherapy in combination with anti-PD1 antibodies in lung, and head and neck cancer patients (head and neck squamous cell carcinoma and non-small cell lung cancer).

The other ongoing NBTXR3 trials are treating patients with liver cancers (hepatocellular carcinoma and liver metastasis), locally advanced or unresectable rectal cancer in combination with chemotherapy, head and neck cancer in combination with concurrent chemotherapy, and prostate adenocarcinoma.

The first market authorization process (CE Marking) is ongoing in Europe in the STS indication.
