Mortality associated with the development of acute liver failure after a single dose of nivolumab.

Immune checkpoint inhibitors have proven to be effective for the treatment of malignant tumors, and although fatalities due to acute liver failure are extremely rare, such cases have been reported previously. Among the immune checkpoint inhibitors, anti-programmed death-1 receptor is associated with less hepatotoxicity. However, even a single dose of this treatment can cause acute liver failure, which could be fatal.
