Scientists hunt for genetic clues to deadly heart side effect of cancer drugs

NCT ID NCT06734689

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

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.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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)
