Scientists hunt for genetic clues to deadly heart side effect of cancer drugs
NCT ID NCT06734689
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to find genetic differences that make some cancer patients more likely to develop a rare but life-threatening heart inflammation (myocarditis) from immune checkpoint inhibitors. Researchers will compare the DNA of 100 patients who had this side effect with 400 who did not. The goal is to identify risk genes and build a score to predict who is most at risk, helping doctors make safer treatment choices.

Inclusion Criteria: 1. 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). 2. Signature of informed consent before any trial procedure from the patient 3. Patients covered by social security regimen (excepting AME). Exclusion Criteria: 1. Age \<18 years of age. 2. Pregnant or breast-feeding women 3. People under legal protection measure (safeguard measures) Specific exclusion criteria for the magnetic resonance imaging sub-study (MRI) * Patients with a contraindication to MRI (claustrophobia, some wearing equipment with magnetic properties: pacemaker, ferromagnetic equipment, etc.) * Intolerance to gadolinium, or severe renal insufficiency (GFR\<30 ml/min/1.73 m2). Of note, the other groups of patients needed to complete this study; i.e the patients with refuted suspicion of ICI-myocarditis who will serve as controls, and the patients with ICI-myocarditis (cases) are included in another protocol (NCT05454527)
