Meta AnalysisIndividual Patient Data Meta-Analysis from 16 Trials for Safety Factors in Cytokine Release Syndrome After CAR-T Therapy in Patients with Non-Hodgkin Lymphoma (NHL) and Acute Lymphoblastic Leukemia.
Chimeric antigen receptor T cells (CAR-T) with anti-CD19 have shown great promise in the treatment of relapsed and refractory non-Hodgkin lymphoma (NHL) and acute lymphoblastic leukemia (ALL). Cytokine release syndrome (CRS) is the most significant and life-threatening side effect. This individual patient data (IPD) meta-analysis is to investigate the association of severe CRS with CAR-T dose and baseline factors. ⋯ Our results provide novel insights that association between CAR-T treatment dose and severe CRS incidence only exists in patients less than or equal to 25 years old. Severe CRS incidence is associated with baseline tumor burden which indicates that tumor burden needs to be controlled with induced chemotherapy before CAR-T treatment.
