辉瑞抗体偶联药物Mylotarg欧洲获批用于治疗急性髓细胞白血病

欧洲食品药品监督管理局批准Mylotarg与柔红霉素和阿糖胞苷联合使用,用于治疗CD33阳性的急性髓细胞白血病(AML)患者,不包括急性早幼粒细胞白血病。

欧洲食品药品监督管理局批准Mylotarg与柔红霉素和阿糖胞苷联合使用,用于治疗CD33阳性的急性髓细胞白血病(AML)患者,不包括急性早幼粒细胞白血病。

AML是一种迅速发展的危及生命的血液和骨髓癌,若不及时治疗,可能会在数周或数月内致命。每年,英国约有2600人受到这种疾病的影响,欧洲各地确诊的新病例约有16800例。Mylotarg是一款抗体偶联药物(ADC),由具有细胞毒素的卡其霉素和靶向功能的CD33单克隆抗体组成。CD33在90%AML患者的成髓细胞表面表达,Mylotarg是通过CD33单抗将卡其霉素靶向运输到AML细胞,实现肿瘤的抑制作用。

辉瑞肿瘤学区域总裁Andreas Penk指出:"临床试验显示标准化疗方案联用Mylotarg会实现更持久的缓解作用,该药物的上市将为AML患者提供新的治疗选择,有可能防治患者的复发。"

临床试验显示,接受治疗的患者与接受目前临床最佳治疗方案的患者相比,存活时间更长,中位生存期达4.9个月(对照组为3.6个月)。另一项数据显示Mylotarg治疗后,26%的患者达到完全缓解,持续时间中位数为11.6个月。

Mylotarg在欧洲获批将会给AML患者带来新的治疗方案,该药物也是欧盟批准的第一种也是唯一一种靶向CD33的抗AML疗法。
