中文摘要

靶向 CD19 的 CAR-T 细胞疗法 brexucabtagene autoleucel(brexu-cel)显著改善了复发/难治性套细胞淋巴瘤(r/r MCL)患者的治疗结局。持续性血细胞减少和感染是常见且具有临床意义的副作用。在这项多中心观察性研究中,我们描述了接受 brexu-cel 治疗的 103 例 r/r MCL 患者的血细胞减少和感染情况,并报告基线 CAR-HEMATOTOX(HT)评分与毒性事件、非复发死亡率(NRM)及无进展/总生存期(PFS/OS)之间的关联。淋巴细胞清除治疗时,56 例患者 HT 评分较低(0–1 分),47 例评分较高(2 分)。

HT 高分组的中性粒细胞减少持续时间更长(中位数 14 天 vs. 6 天,p < 0.001),严重感染率也更高(30% vs. 5%,p = 0.001)。总体 1 年 NRM 为 10.4%,主要归因于感染;基线 HT 评分不同的患者 NRM 有差异(高分组 vs. 低分组:17% vs. 4.6%,p = 0.04)。HT 高分患者的 90 天完全缓解率较低(68% vs. 93%,p = 0.002),PFS 较差(中位数 9 个月 vs. 未达到,p < 0.0001),OS 也较差(中位数 26 个月 vs. 未达到,p < 0.0001)。多变量分析显示,HT 高分与严重血液学毒性、感染以及较差的 PFS/OS 独立相关。

总之,brexu-cel 治疗后感染和血液学毒性较常见,并会导致 NRM;基线 HT 评分可识别治疗结局不佳风险升高的患者。

CD19-directed CAR T-cell therapy with brexucabtagene autoleucel (brexu-cel) has substantially improved treatment outcomes for patients with relapsed/refractory mantle cell lymphoma (r/r MCL). Prolonged cytopenias and infections represent common and clinically relevant side effects. In this multicenter observational study, we describe cytopenias and infections in 103 r/r MCL patients receiving brexu-cel.

Furthermore, we report associations between the baseline CAR-HEMATOTOX (HT) score and toxicity events, non-relapse mortality (NRM), and progression-free/overall survival (PFS/OS). At lymphodepletion, 56 patients were HT low (score 0-1) while 47 patients were HT high (score 2). The HT high cohort exhibited prolonged neutropenia (median 14 vs. 6 days, p < . 001) and an increased rate of severe infections (30% vs. 5%, p = . 001).

Overall, 1-year NRM was 10. 4%, primarily attributed to infections, and differed by baseline HT score (high vs. low: 17% vs. 4. 6%, p = . 04). HT high patients experienced inferior 90-day complete response rate (68% vs. 93%, p = . 002), PFS (median 9 months vs. not-reached, p < . 0001), and OS (median 26 months vs. not-reached, p < . 0001). Multivariable analyses showed that high HT scores were independently associated with severe hematotoxicity, infections, and poor PFS/OS.

In conclusion, infections and hematotoxicity are common after brexu-cel and contribute to NRM. The baseline HT score identified patients at increased risk of poor treatment outcomes.
