Oncolytic viruses (OVs) provide a novel cancer treatment strategy, with a mechanism of action and toxicity profiles that are distinctly different to those of more traditional therapies. Thus far, four OVs have entered clinical use globally, yet only talimogene laherparepvec (T-VEC) has entered widespread clinical use. In this Review, the authors describe the clinical and regulatory experience with T-VEC thus far, and how this can guide the development of novel OVs. Discussions of a range of novel OVs with the potential for clinical implementation in the near future are also provided.
