Programmed cell death protein 1 (PD-1) and vascular endothelial growth factor (VEGF) are often co-expressed in the tumor microenvironment. The combination of anti-PD-1 and anti-VEGF agents has been evaluated in patients with advanced non-small-cell lung cancer, with promising results from agents like ivonescimab, a PD-1/VEGF bispecific antibody.
