Blincyto适应症扩容:MRD阳性ALL

2018-04-07 MedSci MedSci原创

美国食品和药物管理局已批准Blincyto(blinatumomab)治疗患有B细胞前体急性淋巴细胞白血病(ALL)且缓解但仍有微小残留病(MRD)的儿童。 MRD是指在显微镜下可以看到的低水平癌细胞的存在。对于这种初始治疗后获得缓解的患者,MRD的存在意味着复发风险的增加。

美国食品和药物管理局已批准Blincytoblinatumomab)治疗患有B细胞前体急性淋巴细胞白血病ALL)且缓解但仍有微小残留病(MRD)的儿童 MRD是指在显微镜下可以看到的低水平癌细胞的存在。对于这种初始治疗后获得缓解的患者,MRD的存在意味着复发风险的增加。

FDA的肿瘤中心主任兼FDA药物评估中心血液和肿瘤产品办公室主任Richard Pazdur博士说,这是FDA批准的第一个MRD阳性ALL患者的治疗方案。患有MRD的患者更有可能复发,因此拥有可以消除非常低量的残余白血病细胞的治疗药物可能有助于患者获得更长生存时间。目前正在进行研究以评估Blincyto如何影响MRD患者的长期生存结果

FDA201412月首次批准Blincyto,用于治疗费城染色体(Ph)阴性复发或难治性B细胞前体ALLBlincytoMRD阳性ALL中的疗效显示在一项单臂临床试验中,86名患者在第一次或第二次完全缓解后,在其骨髓中检测到了痕量的白血病细胞。除维持生存(血液学无复发生存期)之外,评价Blincyto效力的主要指标即为治疗后检测不到MRD。结果显示,在一个周期的Blincyto治疗后,70名患者体内已经检测不到MRD
