Genetic Determinants of Myocarditis Induced by Immune-checkpoint Inhibitors
France500 participantsStarted 2025-09-23
Plain-language summary
Immune checkpoint inhibitors (ICI) are active in multiple cancers. Their main drawback is the incidence of immune related adverse events; among which ICI-myocarditis (ICIM) is rare but can be the most life-threatening (up to 50% lethal). ICIM is due to ICI unleashing cytotoxic auto-reactive T-cells recognizing a culprit target antigen located on muscles and destroying them. Most often, ICIM occurs within a systemic ICI-myotoxicity, with peripheral muscular involvement (ICI-myositis), mimicking eventually myasthenia-gravis syndrome. Human Leukocyte Antigen (HLA) are cell surface proteins key for the regulation of the immune system acting via presentation of culprit antigens by antigen presenting cells (macrophages) to T-cells, subsequently triggering the destruction/tolerance of cells carrying this antigen. The HLA system (chromosome 6) is the most polymorphic region in the human genome and is associated with auto-immunity including myocarditis. HLA class I alleles have been strongly associated with some T-cell-mediated drug hypersensitivity reactions with handful patients needed to be tested to prevent a single case, leading to globally required cost-effective HLA typing pre-prescription for some drugs.

Inclusion criteria
. Cancer patients on ICI since at least 3 months with a minimum of 2 ICI doses received having no appearance (as compared to baseline known pre-ICI) of a new cardio-muscular symptoms or ECG abnormality or WMA or troponin-T increase (above ULN if normal prior to ICI start, or over twice its troponin-T baseline value if abnormal before ICI start).
. Signature of informed consent before any trial procedure from the patient
. Patients covered by social security regimen (excepting AME).
Exclusion criteria
. Age \<18 years of age.
. Pregnant or breast-feeding women
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

1
Identify common and rare variants in HLA regions and elsewhere in the genome associated with ICI Myocarditis.
Timeframe: Baseline before ICI start and one follow-up point between 3 to 6 months after ICI
