Immune-related adverse events of immune checkpoint inhibitors: a review

Abstract: Since the first Immune Checkpoint Inhibitor was developed, tumor immunotherapy has entered a new era, and the response rate and survival rate of many cancers have also been improved. Despite the success of immune checkpoint inhibitors, resistance limits the number of patients who can achieve a lasting response, and immune-related adverse events complicate treatment. The mechanism of immune-related adverse events (irAEs) is unclear. We summarize and discuss the mechanisms of action of immune checkpoint inhibito… Show more

“…Immune checkpoint blockade, a cornerstone of anti-cancer therapy, aims to inhibit T cell inhibitory receptors like PD-1 and CTLA-4 (69). However, this approach can lead to side effects such as T cell functional exhaustion and immune-related adverse events due to T cell overactivation (70)(71)(72). Our findings reveal that Flot2 deficiency enhances T cell responsiveness to low TCR stimulation, resulting in improved effector responses and tumor control in an in vivo tumor model, while mitigating T cell functional exhaustion.…”

“…Neurological Immune-related adverse events (NirAEs) are considered infrequent and classically described in about 1% of patients [ 3 ]. However, they have been reported more frequently in recent years: 1 to 6% in those receiving monotherapy and up to 14% in those receiving ICI combinations [ 4 ].…”

“…However, they have been reported more frequently in recent years: 1 to 6% in those receiving monotherapy and up to 14% in those receiving ICI combinations [ 4 ]. Despite their low incidence, NirAEs require significant attention, as they can significantly impact the quality of life and may even be fatal [ 3 ].…”

“…The activation of the immune system by checkpoint inhibition can lead to undesired off-target effects manifested as autoinflammatory conditions that can occur in any organ. With increasing knowledge of these potentially life-threatening side effects, clinical treatment guidelines for the common irAEs have been established [2][3][4]. Generally, treatment for irAEs is based on corticosteroids, while higher grades of irAE require additional immunosuppressants, and can lead to withholding or cessation of ICI treatment [3][4][5].…”
