Talimogene laherparepvec (T-VEC) is an oncolytic virus (OV) therapy derived from the JS1 strain of herpes simplex virus one (HSV-1) that was approved by the Food and Drug Administration in 2015 to be administered as a direct injection therapy for patients with melanoma. The anti-tumor effects of T-VEC are due to viral-mediated tumor cell lysis at the site of administration and a local, and in some cases systemic, anti-tumor response via T cell-mediated host immune response pathways aided by GM-CSF. T-VEC has shown promising results for metastatic melanoma, particularly in patients with skin, lymph node, and soft tissue metastases (stages IIIB, IIIC, and IVa). Studies have explored the utility of T-VEC as monotherapy, neoadjuvant therapy, and in combination with other immunotherapies and targeted therapies. T-VEC has proven to improve durable response rates and overall survival with a very tolerable safety profile. More research is needed to better understand which patients are most likely to benefit from T-VEC therapy, which combination therapies are most effective, and how to sequence multimodality therapy. Additionally, new OVs are currently in development and/or being studied in clinical trials. In this review, we will discuss T-VEC as a monotherapy, neoadjuvant therapy, and combination therapy, in addition to future directions for melanoma therapy as it pertains to new OVs.
