NEJM:伊布替尼-利妥昔单抗治疗慢性淋巴细胞白血病

2019-08-01 MedSci MedSci原创

研究认为,对于未经治疗的慢性淋巴细胞白血病患者,伊布替尼-利妥昔单抗的疗效优于标准化疗

近日研究人员比较了伊布替尼-利妥昔单抗疗法与氟达拉滨、环磷酰胺和利妥昔单抗标准疗法对慢性淋巴细胞白血病(CLL)的疗效。

本次研究为III期临床研究,70岁及以下未经治疗的CLL患者接受6轮的伊布替尼-利妥昔单抗治疗,随后接受伊布替尼维持治疗或6轮的标准治疗。研究的主要终点为无进展生存或总生存。

529名患者参与研究,其中354人接受伊布替尼-利妥昔单抗治疗,175人接受标准治疗,平均随访33.6个月。伊布替尼-利妥昔单抗治疗的效果优于标准治疗(3年无进展生存率89.4% vs 72.9%,进展或死亡HR=0.35)。伊布替尼-利妥昔单抗治疗的总生存率优于标准治疗(3年总生存率98.8% vs 91. 5%,死亡HR=0.17)。无免疫球蛋白重链可变区突变患者(IGHV)的亚组分析,伊布替尼-利妥昔单抗治疗的效果优于标准治疗(3年无进展生存率90.7% vs 62.5%,进展或死亡HR=0.26)。IGHV亚组中,伊布替尼-利妥昔单抗治疗的效果与标准治疗组相当(3年无进展生存率87.7% vs 88.0%)。组间3级及以上不良事件率相当,伊布替尼-利妥昔单抗治疗组感染风险更低。

研究认为,对于未经治疗的慢性淋巴细胞白血病患者,伊布替尼-利妥昔单抗的疗效优于标准化疗。
