Ang-2/VEGF bispecific antibody reprograms macrophages and resident microglia to anti-tumor phenotype and prolongs glioblastoma survival

Abstract

Improving survival of patients with glioblastoma (GBM) using antiangiogenic therapy remains a challenge. In this study we show that dual blockade of angiopoietin-2 and vascular endothelial growth factor delays tumor growth and enhances survival benefits through reprogramming of tumor-associated macrophages toward an antitumor phenotype as well as by pruning immature tumor vessels. The antitumor immunomodulatory potential of this dual blockade supports clinical testing of this approach for GBM with other immunotherapeutic approaches such as checkpoint blockers.
