    Immune-Related Adverse Events for Lung Toxicity - Pneumonitis

    Grades severity of pneumonitis secondary to immune checkpoint inhibitor therapy.

    INSTRUCTIONS

    Use in adult patients with symptoms of pneumonitis or focal or diffuse inflammation of the lung parenchyma typically identified on CT imaging while on treatment with immune checkpoint inhibitors.

    When to Use
    Pearls/Pitfalls
    Why Use

    Adult patients with symptoms of pneumonitis (cough, wheezing, fatigue, chest pain) or focal or diffuse inflammation of the lung parenchyma while on treatment with immune checkpoint inhibitors including agents against PD-1 (i.e., pembrolizumab, nivolumab), PD-L1 (i.e., atezolizumab, avelumab, durvalumab), or CTLA-4 (i.e., ipilimumab).

    • Immune checkpoint inhibitor (ICPi) pneumonitis should be suspected in patients with symptoms of pneumonitis (cough, wheezing, fatigue, chest pain) or those with focal or diffuse inflammation of the lung parenchyma, typically identified on CT imaging while on treatment with immune checkpoint inhibitors.

    • Immune checkpoint inhibitor (ICPi) pneumonitis is an uncommon but potentially serious toxicity. 

    • May occur any time during immune checkpoint inhibitor treatment with a range of 2-24 months. Median time to onset is approximately 3 months. 

    • More frequently seen with anti-PD1 agents, but is also an important adverse event caused by anti-CTLA-4 agents.

    • Management of immune checkpoint inhibitor pneumonitis is based on the grade of pneumonitis.

    ICPi pneumonitis is a rare but potentially life threatening toxicity of immune checkpoint inhibitors. This tool aids in the decision to discontinue ICPI, further diagnostic work-up and immunosuppressant treatment initiation.

    Asymptomatic, confined to one lobe of the lung or <25% of lung parenchyma, clinical, or diagnostic observations only
    Symptomatic, involves more than one lobe of the lung or 25-50% of lung parenchyma, medical intervention indicated, limiting instrumental ADL
    Severe symptoms, hospitalization required, involves all lung lobes or >50% of lung parenchyma, limiting self-care ADL, oxygen indicated
    Life-threatening respiratory compromise, urgent intervention indicated (intubation)
