ABSTRACT
Chimeric antigen receptor T cell (CAR-T) therapy is effective in treating relapsed/refractory B-cell acute lymphoblastic leukemia (R/R B-ALL). However, the side effects of immune effector cell-associated neurotoxicity syndrome (ICANS) remain a problem. The current frontline therapies for ICANS include steroids and supportive care. For the steroid-refractory and severe ICANS, several studies have reported excellent efficacy of intrathecal (IT) corticosteroids alone or in combination with chemotherapy. However, whether patients can benefit from IT dexamethasone (dex) before grade 3 or refractory ICANS remains unclear. In this study, the patients with ICANS (≥1) after CAR-T cell therapy were assigned to the IT group and non-IT group. Clinical information, laboratory parameters, and serum cytokine levels were analyzed. A significant and rapid reduction in inflammatory cytokines and biomarkers was observed after 24 h of IT dex treatment. With IT dex, 83.3 % (15/18) of patients recovered from neurotoxicity. Moreover, this option significantly shortens the recovery time of ICANS without affecting the efficacy of CAR-T cell therapy. Earlier initiation of IT dex is the optimal management of ICANS resulting from CAR-T cell therapy, but larger sample studies are needed to determine its efficacy in these settings.
