Immune checkpoint inhibitors are broadly active treatments for cancer, but they can result in immune-related adverse events. Immune checkpoint inhibitor–induced myocarditis occurs infrequently (in <1% of patients who receive these agents), but it is often associated with concurrent myositis and a myasthenia gravis–like syndrome, and it is fatal in up to half of patients with this condition.
We present a case in which the use of abatacept (a cytotoxic T-lymphocyte–associated antigen [CTLA-4] agonist) led to resolution of severe, glucocorticoid-refractory myocarditis that was induced by an immune checkpoint inhibitor.
