中文摘要

非 ICANS 神经毒性(NINTs)是与 ciltacabtagene autoleucel 相关的严重、非典型毒性,ciltacabtagene autoleucel 是一种获批用于复发/难治性多发性骨髓瘤的商业化嵌合抗原受体(CAR)T 细胞疗法。导致 NINTs 发生的危险因素目前了解甚少。在一个 109 例患者的队列中,我们确定了易感危险因素,并提出减轻 NINTs 的策略。

我们发现,高峰值绝对淋巴细胞计数是 NINT 的强预测因子,其与基于流式细胞术的外周血 CAR-T 细胞定量直接相关。观察到的 CAR 淋巴细胞增多为多克隆,并偏向于富含记忆标志物表达的 CD4 + CAR-T 细胞。随后,我们鉴定了与 CAR 淋巴细胞增多相关的 CD4 + CAR-T 细胞群体,这些群体表现出炎症通路基因表达增加。

最后,我们描述了与 NINT 相关的 CD4 + CAR-T 细胞群体,这些群体是未来探索的潜在治疗靶点。

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 count is a strong NINT predictor which directly correlates with flow cytometry-based peripheral blood CAR T cell quantitation. The observed CAR lymphocytosis was polyclonal with a bias towards CD4 + CAR T cells rich in memory marker expression.

We then identified CAR lymphocytosis associated CD4 + CAR T cell populations which exhibited increased inflammatory pathway gene expression.

Finally, we characterize NINT associated CD4 + CAR T cell populations which are potential therapeutic targets for future exploration.
