Robust CD4+ CAR T cell Expansion Is Associated with Non-ICANS Neurotoxicities Following Ciltacabtagene Autoleucel

medRxiv Oncology | |

Non-ICANS neurotoxicities (NINTs) are serious, atypical toxicities associated with ciltacabtagene autoleucel, a commercial chimeric antigen receptor (CAR) T cell therapy approved for relapsed/refractory multiple myeloma. Risk factors contributing to the development of NINTs are poorly understood. In a cohort of 109 patients, we identify predisposing risk factors and propose strategies to mitigate NINTs. We show that high peak absolute lymphocyte…
