Abstract
Talimogene laherparepvec (T-VEC) is the first agent approved for cancer in the emerging class of oncolytic viral therapies. While T-VEC was approved for the treatment of advanced melanoma in 2015, clinical utilization has been hampered by rapid changes in the therapeutic landscape of melanoma related to advances in both immune checkpoint blockade and targeted therapy, cumbersome logistics involved in T-VEC administration, biosafety concerns, and a perception that T-VEC has limited impact on uninjected, visceral disease. However, with further survival follow-up from the phase III OPTiM (OncovexGM-CSF Pivotal Trial in Melanoma), along with new real-world data and consensus guidelines on safe administration of oncolytic viruses, a roadmap for when and how to use T-VEC has been emerging. In addition, preliminary data have demonstrated improved therapeutic responses to T-VEC in combination with immune checkpoint blockade in patients with melanoma without additive toxicity. This review provides an update on recent data with T-VEC alone and in combination with other agents. The emerging data provide guidance for how to better utilize T-VEC for patients with melanoma and identifies critical areas for clinical investigation to expand the role of T-VEC in combination strategies for the treatment of melanoma and perhaps other cancers.
