The history of immunotherapy is rooted in the treatment of melanoma and therapy with immune checkpoint-blocking agents is now a cornerstone for the treatment of metastatic melanoma. The first effective immunotherapies approved by the US Food and Drug Administration in melanoma included interleukin-2 for metastatic disease and interferon alpha in the adjuvant setting. These were followed by a group of new therapies, including checkpoint-blocking antibodies targeting cytotoxic T lymphocyte-associated protein 4 and programmed cell death protein 1. Therapies intended to 'reeducate' T cells, such as tumor-infiltrating lymphocyte therapy, oncolytic viruses and tumor vaccines, have yielded promising results and are under development. Finally, the integration of the above therapies as well as development of new coinhibitory and costimulatory agents, though in early stages, appear very promising and likely represent the next phase in drug development for the treatment of metastatic melanoma.
