Management of Immune-Related Adverse Events Associated with Immune Checkpoint Inhibitor Therapy: A Minireview of Current Clinical Guidelines

Successful targeting and inhibition of the cytotoxic T-lymphocyte-associated antigen 4 and programmed cell death-1 protein/programmed cell death ligand 1 immune checkpoint pathways has led to a rapidly expanding repertoire of immune checkpoint inhibitors for the treatment of various cancers. The approved agents now include ipilimumab, nivolumab, pembrolizumab, atezolizumab, durvalumab, avelumab, and cemiplimab. In addition to antitumor responses, immune checkpoint inhibition can lead to activation of autoreactive T-cells resulting in unique immune-related adverse events (irAEs). Therefore, it is imperative that oncology nurses, and other clinicians involved in the care of cancer patients, are familiar with the management of irAEs which differ significantly from the management of adverse events from cytotoxic chemotherapy. Herein, we review the mechanisms of irAEs and strategies for management of irAEs and highlight similarities as well as differences among clinical guidelines from the National Comprehensive Cancer Network, American Society of Clinical Oncology, Society for Immunotherapy of Cancer, and European Society for Medical Oncology. Understanding these similarities and key differences will facilitate the development and implementation of a practice site-specific plan for the management of irAEs.
