Introduction:Chimeric antigen receptor T cell (CAR-T) therapy harnesses a patient’s own immune system to target cancer. Cardiotoxicity occurs in up to 25% of patients treated with CAR-T. There are limited data characterizing the association between the development of cardiotoxicity after CAR-T and mortality among patients following CAR T cell therapy.Hypothesis:We hypothesized that cardiotoxicity following CAR-T treatment would be associated with a higher rate of mortality. Cardiotoxicity was a composite outcome defined as the development of heart failure, cardiogenic shock, or myocardial infarction.Methods:We included the first 202 adult patients entered into a multicenter registry receiving anti-CD 19 CAR-T for lymphoma or acute lymphoblastic leukemia (ALL). Of these, 108 died and 94 survived. Covariates included standard baseline cardiovascular and cancer parameters, the occurrence of cardiotoxicity and mortality.Results:Those that did and did not die after CAR-T were similar in age, sex, and pre-lymphodepletion chemotherapy regiment. Death after CAR-T was more common in patients with than without hypertension (66% vs. 47%, p=0.009) or ALL (66% vs. 48%, p=0.02), and less common with baseline coronary artery disease (25 vs. 56%, p=0.04). There was no difference in mean cytokine release syndrome (CRS) grade, rate of ≥2 CRS, or in the use of tocilizumab or steroids between those who did and did not die after CAR-T. During a mean follow-up of 372±284 days, 33 (16%) patients experienced cardiotoxicity. Patients with vs. without cardiotoxicity died more often (76% vs. 49%, OR 3.2, CI 1.4 - 7.6, p=0.005). In a Cox model adjusted for covariates identified in univariate analyses, occurrence of cardiotoxicity with CAR-T was independently associated with an increased risk of mortality (adjusted HR: 1.85, 95% CI: 1.17-2.92, p=0.009).Conclusions:CAR-T recipients who experience cardiotoxicity have higher mortality. |
