New study aims to uncover hidden liver risks of immunotherapy
NCT ID NCT04476563
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study observes 160 cancer patients to understand why some develop liver injury from checkpoint inhibitor drugs. Researchers will track blood markers and genetic factors to identify who is at risk. No new treatment is tested; the goal is to improve diagnosis and monitoring.

Who is studied
ChILI group: Adults with cancer receiving checkpoint inhibitors (CTLA-4, PD-1 or PD L1 inhibitor) as monotherapy or combination (without chemotherapy) and developed acute liver injury secondary to checkpoint inhibitor. Control Group: Patients with malignant melanoma, renal cell carcinoma, non-small cell lung cancer or any other cancer, receiving single or combination therapy using checkpoint inhibitors (CPIs).

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: Both patient groups and control group: • Able to give written informed consent OR Potential participants who have developed encephalopathy related to ChILI as a response to checkpoint inhibitor therapy, who lack the capacity to give written informed consent and have a consultee (personal or nominated) - for ChILI patient group only ChILI group: Patients who developed checkpoint inhibitor-induced liver injury and meet the following criteria: 1. Meets one of the following analytical thresholds at enrolment (visit 1) * Alanine transaminase (ALT) exceeding 5 times the upper limit of normal (ULN) OR * ALT exceeding 3 times ULN plus bilirubin exceeding 2 times ULN OR * Alkaline phosphatase (ALP) exceeding 2 times ULN with accompanying elevations of gamma-glutamyl transferase in the absence of known bone metastases driving the rise in ALP level 2. Absence of other known causes of liver injury after detailed investigations Patients who developed ChILI but did not meet the above criteria at enrolment or who were found to have a different cause for their liver injury after further investigations will be excluded from the analysis Control group: Consecutive patients with cancer who have a clinical indication to start checkpoint inhibitors. A small proportion of patients will develop ChILI following their checkpoint inhibitor treatment and will be classified as cases. Exclusion Criteria: * Patients who are treated with cytotoxic chemotherapy concurrently with checkpoint inhibitors. * On the judgment of chief investigator that the person has certain alternative explanations to the acute event (rather than ChILI).
