Safety and Efficacy of p53 Gene Therapy Combined With Immune Checkpoint Inhibitors in Solid Tumors.

This is a Phase 2 study of the combination of Ad-p53 administered intra-tumorally in combination with physician's choice of FDA approved immune checkpoint inhibitor therapy in patients with recurrent or metastatic cancers. This is a safety and efficacy study with a single cohort, consisting of the combination of Ad-p53 and infusions of immune checkpoint inhibitors. Immune checkpoint inhibitor treatments will be administered in accordance with FDA package inserts. Comparison will be made to historical data. General safety and preliminary efficacy will be determined using RECIST 1.1, ECOG status and Immune-Related Response Criteria. Biomarker testing of archival or fresh tissue is performed during the study. Enrollment will be up to 40 patients.
