Limitation of current anti-Vascular Endothelial Growth Factor (VEGF) cancer therapy is transitory responses, inevitable relapses and its insufficient tumor-targeting. Thus, multifaceted approaches, including the development of bispecific antibodies and combination strategies targeting different pathways have been proposed as an alternative.
