Aim. Immune checkpoint inhibitors (ICIs) have improved the survival rate of patients carrying various malignant neoplasms. Despite their efficacy, ICIs occasionally induce liver injury as an immune-related adverse event (irAE). This study aimed to reveal the clinical features of the hepatic irAE in Japanese patients. Methods. Among 387 patients treated with ICIs, those who developed drug-induced liver injury were investigated. We also describe the histological findings and clinical courses of four patients with hepatic irAE who underwent liver biopsy. Results. Among the 56 patients with all-grade liver injury, only 11 (19.6%) showed hepatocellular-type liver injury, which resembled autoimmune hepatitis. Thirty-four patients (60.7%) developed cholestatic or mixed-type liver injury, although only one patient showed abnormal image findings in the bile duct. Most patients with grade ≤2 liver injury improved spontaneously, while two patients with biliary dysfunction required ursodeoxycholic acid or prednisolone. Among eight patients with grade ≥3 liver injury, three required no immunosuppressants and five were treated with prednisolone (three of five patients required other types of immunosuppressants). Four patients in the case series showed diverse clinical features in terms of hepatotoxic pattern, symptoms, and the interval time between the initiation of immunotherapy and the onset of the hepatic irAE. Conclusions. Our findings suggest that ICIs could cause microscopic biliary disorder without any abnormal image finding. Because the hepatic irAE presents diverse clinical features, liver biopsy is recommended to provide appropriate treatments.

e18192 Background: Immunotherapy related adverse events (irAEs) and hospital admissions with Immune Checkpoint Inhibitors (ICIs) in thoracic malignancies remain poorly characterized. Methods: Admissions after ICIs in all thoracic malignancies patients received ICIs at City of Hope (total 384) were identified as of 11/8/2018. IrAEs, outcomes, pathology and next-generation sequencing (NGS) data were collected, including Tumor mutation burden (TMB) and PD-L1 (22C3). Length of stay (LOS) and overall survival (OS) was calculated. Unpaired T-tests if data passed normality test, Chi-square and Fisher’s exact test, Gehan-Breslow-Wilcoxon test were used for comparison between 2 groups (irAEs VS no irAEs) for LOS, demographics and genetics, and survival respectively. Results: 100 patients had hospital admissions after ICIs therapy and 90 patients (41 women, 49 men) had stage IV disease (63 lung adenocarcinomas, 14 squamous cell lung cancer, 5 small cell lung cancer, 8 others). 28 out of 90 patients had irAEs (10 pneumonitis/pneumonia, 4 adrenal insufficiencies, 4 colitis, 3 liver toxicities, 2 nephritis, 1 heart failure, 1 pancreatitis, 1 diabetic ketone acidosis, and others including multiple irAEs). There was no difference between the patients who had irAEs VS no irAEs in LOS (median 7 days VS 6 days, P = 0.57). Patients with irAEs had more invasive diagnostic procedures than no irAEs (53.6% VS 25.8%, P = 0.02). There was a trend of longer OS in irAEs patients (median 16.4 months VS 6.8 months, P = 0.13) than no irAEs. Male gender (71.4% (20/28) VS 46.8% (29/62), OR = 2.85, P = 0.04) and smoking exposure (89.3% (25/28) VS 58.1% (36/62), OR = 6.0, P < 0.01) were associated with irAEs patients. Genetic alterations of LRP1B gene (83.3% (5/6) VS 26.9% (7/26), OR = 13.6, P = 0.02) and MLL3 gene (66.7% (4/6) VS 19.2% (5/26), OR = 8.4, P = 0.04) were associated with patients who had irAES. No difference was found in age, lines of therapy, TP53, KRAS, EGFR, STK11, PIK3CA, TMB, PD-L1 between the irAEs and no irAEs patients. Conclusions: Hospitalized patients who had irAEs had similar LOS compared with patients without irAEs but potentially longer OS. Gender, smoking status and genes associated with irAEs and ICIs outcomes were explored. Larger dataset for molecular and clinical features was planned.
