Several studies reported the improved selectivity and efficacy of chimeric molecules comprised of toxins or other cytotoxic agents with targeting agents on tumor vasculature, such as vascular endothelial growth factor receptor-gelonin; Shiga-like toxin-vascular endothelial growth factor fusion protein and anti-TES-23 linked to neocarzinostatin [17-19]. Here, VEGFA is linked to neoplasm.
