Lancet:Atezolizumab联合Bevacizumab一线治疗晚期肾癌

2019-05-11 MedSci MedSci原创

研究认为,Atezolizumab联合Bevacizumab能延长转移性肾细胞癌患者的无进展生存期,并显示出良好的安全性,支持Atezolizumab联合Bevacizumab作为晚期肾癌患者一线治疗的选择

二期试验显示,PD-L1阳性的转移性肾细胞癌患者中, Atezolizumab联合Bevacizumab疗法相比于舒尼替尼,患者的无进展生存期得到改善。近日研究人员公布了IMmotion 151研究,比较了Atezolizumab联合Bevacizumab一线治疗转移性肾细胞癌的疗效。

透明细胞或肉瘤样组织学转移性肾细胞癌患者参与研究,先前未经过治疗,随机静脉滴注Atezolizumab 1200 mg+ Bevacizumab 15 mg/kg每3周1次或舒尼替尼50 mg,每日1次,连续4周,间隔2周。主要终点是PD-L1阳性人群的无进展生存率和意向治疗(ITT)人群的总生存率。

915名患者中,454名随机接受联合治疗,461名接受舒尼替尼。915例患者中有362例(40%)有PD-L1阳性,中位随访时间为15个月,总体生存期随访时间为24个月。在PD-L1阳性人群中,联合组的中位无进展生存期为11.2个月,而舒尼替尼组的中位无进展生存期为7.7个月(HR=0.74)。在ITT人群中,总生存期中位数HR为0.93无显著性差异。联合组451例患者中有182例(40%)和舒尼替尼组446例患者中有240例(54%)发生了与治疗相关的3-4级不良事件:联合组24例(5%)和舒尼替尼组37例(8%)发生了与治疗相关的所有级别不良事件,导致治疗方案终止。

研究认为,Atezolizumab联合Bevacizumab能延长转移性肾细胞癌患者的无进展生存期,并显示出良好的安全性,支持Atezolizumab联合Bevacizumab作为晚期肾癌患者一线治疗的选择。
