Abstract

Aims: Neurotoxicity (NT) is a common complication of chimeric antigen receptor (CAR) T-cell therapy. Data on early clinical identifiers for impending severe NT are lacking. Methods: The authors performed a retrospective study on 26 adult relapsed/refractory diffuse large B cell lymphoma patients treated with commercial CAR T-cell therapy (December 2017 - September 2018). Results: NT of any grade and severe NT occurred in 88 and 31% of patients, respectively. Dysgraphia (p < 0.01), disorientation (p = 0.01) and inattention (p = 0.018) were associated with severe NT, with positive predictive values of 100, 87.5 and 87.5%, respectively. Dysnomia was not associated with severe NT. Conclusion: In the authors' limited cohort, the dysgraphia, disorientation and inattention components of the CAR T-cell therapy-associated toxicity 10 scoring system were significantly associated with and predictive of impending severe NT.
