J Clin Oncol:博纳吐单抗无反应和高疾病负荷提示,B-ALL患者采用CD19-CAR治疗的预后不良

2021-11-17 Nebula MedSci原创

博纳吐单抗治疗无反应和高疾病负荷与B-ALL患者采用 CD19-CAR 治疗后的预后较差独立相关

CD19 靶向嵌合抗原受体 T 细胞 (CD19-CAR) 和博纳吐单抗可有效诱导复发性或难治性 B 细胞急性淋巴细胞白血病 (ALL) 的缓解,但也与 CD19 抗原调节有关。目前,关于既往有博纳吐单抗暴露对随后接受 CD19-CAR 治疗的结果的影响的数据有效。

这是一项多中心、回顾性的研究,分析了2012年至2019年期间接受 CD19-CAR 治疗的复发性或难治性 ALL 儿童和青少年患者的预后。主要评估了 6 个月的无复发生存率 (RFS) 和无事件生存率(EFS),按博纳吐单抗暴露史进行分层;次要目标包括对比长期生存结果、完全缓解率、CD19 调节以及确定与无事件生存相关的因素。

各亚组患者的累积复发率

在 420 位接受商业 tisagenlecleucel 或研究性 CD19-CAR 构建体(三种中的任一种)治疗的患者(中位年龄 12.7岁;四分位范围 7.1-17.5岁)中,有77位(18.3%)既往接受过博纳吐单抗治疗。与未接受博纳吐单抗治疗的患者相比,接受过博纳吐单抗治疗的患者更常出现 KMT2A 重排,并更可能接受过干细胞移植。在可评估 CD19-CAR 反应的412位患者中,博纳吐单抗治疗无反应者接受 CD19-CAR 治疗的完全缓解率(20/31,64.5%)低于博纳吐单抗反应者(39/42,92.9%)或未接受过博纳吐单抗治疗的患者(317/339, 93.5%),P<0.0001。

CD19-CAR 治疗后,与博纳吐单抗反应者或未接受过博纳吐单抗治疗的患者相比,博纳吐单抗治疗无反应者的6个月 EFS 和 RFS 均最差(EFS:27.3% vs 66.9% vs 72.6;P<0.0001)。

高疾病负荷与较差的 EFS 独立相关。CD19 暗淡或部分表达(输注前)在博纳吐单抗暴露+患者中更常见(13.3% vs 6.5%; P=.06),并且与较低的 EFS 和 RFS 相关。

据了解,这是迄今为止儿童 CD19-CAR 的最大规模的研究,该研究结果表明博纳吐单抗治疗无反应和高疾病负荷与B-ALL患者采用 CD19-CAR 治疗后较差的 RFS 和 EFS 独立相关。
