Co-targeting of VEGFR2 and PD-L1 promotes survival and vasculature normalization in pleural mesothelioma.

ABSTRACT: Pleural mesothelioma (PM) is an aggressive cancer caused by asbestos exposure, with limited treatment options and poor prognosis, highlighting the need for more effective therapies. Combining immune checkpoint blockade with anti-angiogenic therapy has shown potential in other cancers. Our study investigated the combined inhibition of PD-L1 and VEGFR2 in a mouse model of PM. Using C57BL/6 mice with subcutaneous AE17 mesothelioma tumors, we assessed the effects of anti-PD-L1 therapy with induction, concomitant, or consolidation anti-VEGFR2 treatment. Mice received intraperitoneal doses every three days for three treatments. Tumor growth, survival, tumor-infiltrating immune cells and intra-tumoral vasculature were analyzed. Results demonstrated that combining anti-PD-L1 with induction or conc
