NEJM:CAR-NK细胞疗法用于CD19阳性淋巴瘤

研究发现,CAR-NK细胞治疗可改善CD19阳性肿瘤患者症状并且无严重的毒副作用

CD19-CAR-T疗法对B细胞相关肿瘤表现出良好的临床效果,但其仍存在毒性和制备过程复杂的问题,而NK细胞疗法则有望克服CD19-CAR-T的不足。

在近期的I-II 期临床研究中,研究人员将HLA不匹配的 CD19-CAR-NK细胞输注到11名复发或难治性CD19阳性肿瘤患者中(非霍奇金淋巴瘤或慢性淋巴细胞白血病)。研究人员通过逆转录病毒载体转导NK细胞,表达编码抗CD19CAR、白细胞介素-15,诱导caspase9基因作为安全开关。淋巴消耗化疗后,CD19- CAR-NK输注量分别为1×105,1×106或1×107/kg体重。

研究发现,CAR-NK细胞输注后不会引起细胞因子释放综合征、神经毒性或移植物抗宿主病。炎症细胞因子水平,包括白细胞介素-6,无显著增加。研究未达到最大耐受剂量。11名接受治疗的患者中,8名(73%)出现治疗响应,其中7人出现完全缓解,1人出现Richter转化。治疗响应迅速,在治疗后30天内全部出现。CAR-NK输注后的扩增和持续表达至少维持12个月。

研究发现,CAR-NK细胞治疗可改善CD19阳性肿瘤患者症状并且无严重的毒副作用。
