Introduction:Vascular-disrupting agents (VDAs) are a new class of oncology drugs, which specifically target established tumor neovasculature and have a relatively low toxicity profile. VDAs generally have non-overlapping side effects when concomitantly used with conventional cytotoxics. Several members of the VDA class have recently progressed through mid-to-late stages of clinical trials.Areas covered:We examined recent publications on preclinical findings and Phase I/II/III clinical trial data on mechanisms of actions, toxicities, and optimal use of VDA class drugs. It is becoming apparent that VDAs should be used in combination with other classes of cytotoxic agents for the optimization of their effect in treating various cancers. In this article we describe doses, timing of delivery, and sequence of combined therapy. We also address the combined mechanisms of actions of VDAs and conventional cytotoxic medications.Expert opinion:Vascular-disrupting agents represent a new class of promising anticancer agents, which exhibit synergistic and/or additive effects in combination with many conventional cytotoxics. Pharmacological evaluation of the optimal combinations of VDAs with agents of other classes and drug interactions need to be continued. Further clinical and preclinical studies are required for distinguishing cancer patients' subpopulations that would most benefit from VDAs, identifying tumor biomarkers predictive of response as well as reliable and reproducible imaging and/or biological assays indicative of pharmacodynamic effects, and establishing clinical algorithms for treatment.
