Combinations of chemotherapy with anti-stabilin1 antibody and/or FOXP3 inhibitor (AZD8701), FOXP3i, significantly increased median survival of mice with established peritoneal disease...There was significant reduction in FOXP3 positive cells and significant increase of Tbet positive cells in FOXP3i treated murine tumors suggesting repolarization of naive T cells in the tumor microenvironment towards a more anti-tumor T helper phenotype. As there are early phase clinical trials of FOXP3 inhibitor and anti-stabilin1 (Clever-1) antibody in patients with advanced cancer, these results suggest ways of improving response to chemotherapy not only in HGSOC but in other cancers that are treated by NACT.
This is a Phase I multicenter study of AZD8701 alone or in combination with durvalumab in participants with selected advanced solid tumors. Secondary endpoints include, disease control rate, duration of response, progression free survival and overall survival, pharmacokinetics and pharmacodynamics (including changes in Foxp3 mRNA in paired tumor samples). The trial is currently recruiting.
