NANOBIOTIX Reports New Data for Potential First-in-Class Radioenhancer NBTXR3 in Combination With Anti-PD-1 Showing Local or Distant Tumor Regression in 76.9% of Evaluable Patients Regardless of Prior Anti-PD-1 Exposure Results show NBTXR3 plus radiotherapy could potentially stimulate immune response and convert anti-PD-1 non-responders into responders Objective response was observed in 60% of anti-PD-1 naïve patients and 50% of prior non-responders Data suggest abscopal effect in some patients (i.e., reduction in non-injected non-irradiated lesions) To date, the overall adverse event profile for the 16 injected patients has not differed from what is expected with radiotherapy or anti-PD-1 agents (head and neck cancer and non-small cell lung cancer primary tumors)
