Management of Immune Checkpoint Inhibition-related Hepatitis Using Low-dose Corticosteroids

Inclusion Criteria: 1. Cancer patients aged 18 years or older 2. Treatment with a programmed cell death protein 1 (PD-1) or programmed cell death ligand 1 (PD-L1) antibody, or a cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) antibody, or a combination of a PD-1 and CTLA-4 antibody, or a PD-1 and lymphocyte-activation gene 3 (LAG-3) antibody 3. Occurrence of immune-related hepatitis grade 2 to 3 (as per judgment of the investigator) 4. Ability of the patient to comply with the study procedures (management of immune-related hepatitis) Exclusion Criteria: 1. Previous Immune-related hepatitis that required systemic therapy 2. Treatment for Immune-related hepatitis has already been initiated with high-dose corticosteroids (\>0.5 mg/kg body weight) 3. Immune-related hepatitis with bilirubin \> 1.5 ULN or clinical suspicion of cholangitis or elevated INR (beyond baseline) 4. Immune-related hepatitis with grade 4 at first presentation 5. Prior irAE treated with systemic immunosuppression 6. Simultaneous immune-related neurological toxicity or immune-related myocarditis (since these usually have to be treated with high doses of corticosteroids) a. Patients with other immune-related adverse events may be included according to the investigator's judgment 7. Known liver disease (e.g., autoimmune hepatitis, active hepatitis B, C or E, hemochromatosis, liver cirrhosis Child-Pugh Score B or C, primary biliary cholangitis, primary biliary cirrhosis, Morbus Wilson) a. Patients with liver metastasis are eligible 8. Patients receiving cancer treatment other than immune checkpoint inhibitors in parallel (e.g., tyrosine kinase inhibitors or chemotherapy). a. Patients who have received other cancer treatments in previous cycles are eligible, provided the treating physician does not assume any toxicity from the other medication. 9. Condition requiring systemic treatment with either corticosteroids or other immunosuppressive medications within 14 days prior to occurrence of IR hepatitis. Stable corticosteroid doses of \< 10mg prednisone equivalent are allowed.
