Immune Checkpoint Therapies for Melanoma

Immunotherapy with immune checkpoint inhibition has dramatically changed the treatment of melanoma. Immune checkpoint inhibitors targeting cytotoxic T-lymphocyte-associated protein 4 and programmed cell death protein 1 are approved for the treatment of advanced melanoma alone and in combination. In addition, these agents are approved for use in high-risk resected stage III melanoma in the adjuvant setting. Clinical trials testing the combination of immune checkpoint inhibition with other therapies and novel immunotherapies continue. This article reviews the current literature on approved uses of immune checkpoint inhibition in melanoma and discusses ongoing trials and future directions.
