Early heart function check after CAR-T treatment

Early Assessment of Cardiac Function After Treatment With CAR-T Cells

Assistance Publique - Hôpitaux de Paris · NCT06350994

We will test whether people treated with CAR‑T cells for blood cancers have early changes in heart function by doing an ultrasound and blood tests 3–5 days after infusion.

What this trial studies

This observational study screens patients who receive CAR‑T cell therapy for early cardiac dysfunction using bedside transthoracic echocardiography between days 3 and 5 after infusion. The primary outcome is the change in left ventricular ejection fraction (LVEF) from the pre‑CAR‑T baseline to the early post‑infusion echocardiogram, and routine biomarkers (BNP, troponin) and ECGs are also recorded. Eligible participants are those with a pre‑therapeutic cardiac assessment who receive CAR‑T treatment at the participating center. The aim is to estimate the incidence of early cardiotoxicity and to detect asymptomatic heart dysfunction that may be missed without systematic early screening.

Who should consider this trial

Good fit: Ideal candidates are patients with hematologic malignancies who receive CAR‑T infusion, have a pre‑treatment echocardiogram and ECG, and can undergo bedside echocardiography 3–5 days after infusion.

Not a fit: Patients who lack a pre‑CAR‑T cardiac assessment, cannot attend the in‑hospital 3–5 day window, decline participation, or are too unstable for bedside imaging are unlikely to benefit from this screening protocol.

Why it matters

Potential benefit: If successful, this approach could help clinicians detect and treat early CAR‑T–related heart problems sooner, potentially reducing related complications and ICU stays.

How similar studies have performed: Previous reports have documented acute cardiac events after CAR‑T therapy, but systematic early bedside echocardiographic screening is relatively novel and not yet proven to change outcomes.
