Talimogene Laherparepvec for the Treatment of Advanced Melanoma.

Abstract

Talimogene laherparepvec (T-VEC) is a first-in-class oncolytic virus that mediates local and systemic antitumor activity by direct cancer cell lysis and an "in situ vaccine" effect. Based on an increased durable response rate compared with granulocyte macrophage-colony stimulating factor in a randomized phase III trial, it was approved by the FDA for the treatment of melanoma metastatic to skin or lymph nodes. The drug is currently in clinical trials as monotherapy and in combination with immune-checkpoint inhibitors and radiotherapy in melanoma and other cancers. The mechanism of action, toxicity, and efficacy as well as its role in current clinical practice and potential future applications are reviewed. Clin Cancer Res; 22(13); 3127-31. ©2016 AACR.
