Spots Global Cancer Trial Database for Early Assessment of Cardiac Function After Treatment With CAR-T Cells

Study Description

Brief Summary: CAR-T cells (Chimeric Antigen Receptor) are a new immunotherapy, based on the genetic modification of autologous T lymphocytes. CAR-T cell therapy is not devoid of complications. Among the most frequent complications are the risk of infection, cytokine release syndrome (CRS) and neurotoxicity. Nevertheless, some authors have reported serious acute cardiac events in a limited number of patients, often contemporaneous with CRS or sepsis, questioning the imputability of CAR-T cells in this heart disease. This study aims to estimate the incidence of a possible early cardiotoxicity associated with CAR-T cells. The main endpoint will be the change in cardiac function (LVEF: left ventricular ejection fraction) assessed by ultrasound between the pre CAR-T assessment and the early post CAR-T ultrasound (D3-D5).

Detailed Description: CAR-T cells (Chimeric Antigen Receptor) represent a new form of immunotherapy, based on the genetic modification of autologous T lymphocytes collected after apheresis, allowing the recognition of a tumor antigen apart from the presentation by the major complex of histocompatibility (MHC). Treatment with CAR-T cells constitutes a major therapeutic advance in patients with refractory hematological malignancies. Nevertheless, CAR-T cell therapy is often associated with severe complications leading them to the ICU in \>25%. Among the most frequent complications are the risk of infection cytokine release syndrome (CRS)and neurotoxicity. A recent study reported serious acute cardiac events in the days following the administration of CAR-T cells in 6.5% of patients (12/187). In this work, patients did not benefit from systematic early echocardiography, but only in the event of CRS grade ≥2 or symptoms, with a risk of underdiagnosis of asymptomatic forms. Since the vast majority of reported cases are contemporaneous with CRS or sepsis, the imputability of CAR-Ts in this heart disease is debated. The Cardio CAR-T study aims to investigate a possible early cardiac toxicity of CAR-T cells, screened by transthoracic echocardiography at the patient's bedside, between D3 and D5 after injection of CAR-T cells (period at which the inflammatory complications of this treatment occur in the majority of cases) associated with the description of routine examinations (BNP, Troponin and ECG) and cytokine analyses. This pilot descriptive study would answer 2 questions: * What are the incidence and characteristics of acute cardiac toxicity (clinical and subclinical) of CAR-T cells and their association with CRS? * Is there a link between cardiac toxicity and the intensity of the cytokine inflammatory response? This makes it possible to provide new pathophysiological elements on the existence of a heart disease directly caused by the inflammatory storm, applicable to other areas such as septic shock, ischemia-reperfusion or major surgery.
