Abstract: This invention provides methods to overcome the current limitations of immune checkpoint immunotherapy to provide more effective methods of treating cancer. In embodiments this invention provides a means of using of p53 gene therapy to augment immune checkpoint inhibition by combining antibodies targeting immune checkpoint molecules with SGT-53, a nanomedicine carrying a plasmid encoding human wild-type p53. This invention provides means of increasing tumor immunogenicity, enhancing both innate and adaptive immune responses, and reducing tumor-induced immunosuppression, sensitizing otherwise refractory tumors to anti-immune checkpoint antibodies. In other embodiments this invention also unexpectedly reduces immune-related toxicities that are seen with immunotherapies.
