The most common adverse event associated with chimeric antigen receptor T-cell therapy is cytokine release syndrome, which is characterized by fever, hypoxia, and hypotension in varying degrees of severity. In severe cases, cytokine release syndrome can result in life-threatening symptoms such as multi-organ failure. The widely accepted first-line therapy for cytokine release syndrome management is tocilizumab with or without corticosteroids, but there is very limited guidance on the proper management of patients unresponsive to this regimen. There are emerging strategies that target cytokine release syndrome through novel mechanisms, showing promise in treating or preventing severe cytokine release syndrome. Although further clinical investigation is necessary to assess the applicability of the emerging approaches, these exploratory therapies may shape the future landscape of chimeric antigen receptor T-cell induced cytokine release syndrome management. This review article provides a comprehensive overview of the current and emerging therapies for the management of chimeric antigen receptor T-cell induced cytokine release syndrome, especially cases that are refractory to tocilizumab and steroids.

Background: An excessive immune response during coronavirus disease (COVID-19) can induce cytokine release syndrome (CRS), which is associated with life-threatening complications and disease progression. Methods: This study was aimed to investigate the differences and similarities between CRS induced by COVID-19 and CAR-T therapy, then provide valuable experiences for early identification and controlling CRS progression in COVID-19. We retrospectively evaluated the clinical characteristics of severe CRS (sCRS, grade 3-4) induced by COVID-19 (40 patients) or chimeric antigen receptor T-cell (CAR-T) therapy as a comparator (41 patients). Results: Grade 4 CRS was significantly more common in the COVID-19 group (15/40 [35.7%] vs. 5/41 [12.2%], P=0.008). CAR-T group had more more dramatic increase in cytokine than COVID-19 group (Figure1), including IL-2 (7.3pg/mL [IQR: 2.0-12.7] vs.1.7 [0.7-2.7], P<0.001), IL-6 (7120.6 pg/mL [1066.8-15 136.4] vs. 110.3 [41.7-728.1], P<0.001), IL-10 (174.5pg/mL [61.7, 434.6] vs. 10.1 [6.3-20.6], P<0.001) and IFN-γ (1308.5pg/mL [296.6, 3108.2] vs .35.0 [16.9-60.8], P<0.001). Interestingly, COVID-19 group had significantly higher levels for TNF-α (31.1 pg/ml [16.1-70.0] vs. 3.3 [1.8-9.6], P<0.001).The correlations between viral load/ tumor burden and various cytokine levels were shown in Figure 2. Lg viral loads were correlated with lg IL-6 (R2=0.101; P<0.001) and lg IL-10 (R2=0.105; P<0.001) .In CAR-T group, LDH was a common indicator related to tumor burden among patients with ALL, NHL, and MM. The lg LDH concentration was correlated with the lg serum concentration of IL-6 (R2=0.161; P=0.01). The independent risk factors for COVID-19-related sCRS were hypertension history (OR: 7.167, 95% CI: 2.345-21.903; P=0.001) and minimum platelets <100×109 /L during disease course (OR: 9.237, 95% CI: 2.544-33.546; P=0.001). Conclusion: Our study demonstrated that there were similar processes but different intensity of inflammatory responses of sCRS in COVID-19 and CAR-T group. The diagnose and management of COVID-19 related sCRS can learn lessons from treatment of sCRS induced by CAR-T therapy.

Abstract Chimeric antigen receptor-T cell (CAR-T) therapy in T cell malignancies faces fratricide, T cell aplasia, and product contamination. Here, we successfully developed a universal anti-CD7 CAR-T product (RD13-01). RD13-01 contains a bbzg-CAR comprising an anti-CD7 single-chain variable fragment, a 4-1BB costimulatory domain, a CD3ζ signaling domain, the intracellular domain of the common γ chain, and a natural killer cell inhibitory molecule (E-cadherin). TRAC, CD7 and HLA-II were disrupted to avoid graft versus host disease (GvHD), fratricide and rejection. Bbzg-CAR-T exerted antitumor effects superior to those of conventional CAR-T, while exhibiting reduced cytokine production. Among 11 evaluable relapsed/refractory (r/r) patients, no dose-limited toxicity, GvHD, immune effector cell-associated neurotoxicity or severe cytokine release syndrome (grade≥3) occurred. Nine (82%) showed objective response. For r/r leukemia and NHL, complete response rates were 75% and 33.3% respectively. Outstanding safety and efficacy of this universal CAR-T product was achieved in CD7+ T cell malignancies.
