Although treatment of high-dose (HD) radiation (XRT) and NBTXR3 (R3) on primary tumors in combination with systemic anti-PD1 was able to significantly improve abscopal effect in 344SQR murine metastatic lung cancer, most of the mice eventually expired due to the growth of metastatic tumors. Therefore, we studied the effects of R3 injection into primary tumors plus high-dose radiation on primary tumor and low-dose raditionon metastatic tumor plus dual-agent immunotherapy (IT) of anti-PD1 and anti-CTLA-4 to achive complete control of tumor growth at both the primary and the metastatic tumors in mice.

For decades, radiotherapy (RT) has been a cornerstone of cancer treatment. Currently, approximately 50% of cancer patients will be treated with RT. Beyond the ability of RT to produce free radicals and to generate single and double-strand breaks in DNA, triggering cell death, preclinical and clinical studies have demonstrated that RT can have immunomodulatory effects. For example, RT can stimulate MHC class I expression on cancer cells, induce immunogenic cell death (ICD), and activate expression of various pro- and anti-inflammatory cytokines and adhesion molecules, allowing recruitment and activation of both innate and adaptive immune cells into the tumor.
