NEJM:未经治疗晚期黑色素瘤患者该采用瑞拉利单抗-纳武单抗组合治疗还是单独纳武单抗治疗?

2022-01-06 MedSci原创 MedSci原创

在既往未经治疗的转移性或无法切除的黑色素瘤患者中,抑制两个免疫检查点LAG-3和PD-1比单独抑制PD-1在无进展生存方面可获得更大的益处。

淋巴细胞激活基因3(LAG-3)和程序性死亡1(PD-1)是不同的抑制性免疫检查点,可导致T细胞衰竭。瑞拉利单抗(LAG-3阻断抗体)和纳武单抗(PD-1阻断抗体)的组合已被证明对既往接受过治疗的黑色素瘤患者是安全的,并具有抗肿瘤活性,但它们在既往未经治疗的黑色素瘤患者中的安全性和活性需要进一步调查。

近日,顶级医学期刊NEJM上发表了一篇研究文章,在这项2-3期、全球、双盲、随机试验中,研究人员评估了每4周静脉注射固定剂量的瑞拉利单抗和纳武单抗组合治疗与单独使用纳武单抗治疗既往未经治疗的转移性或无法切除的黑色素瘤患者的比较疗效。该研究的主要终点是通过盲法独立审查评估的无进展生存期。

瑞拉利单抗–纳武单抗组合治疗患者的中位无进展生存期为10.1个月(95%CI为6.4至15.7),而单独采用纳武单抗治疗的患者中位无进展生存期为4.6个月(95%CI为3.4至5.6)(进展或死亡的风险比为0.75[95%CI为0.62至0.92];对数秩检验P=0.006)。

瑞拉利单抗-纳武单抗组合治疗患者的12个月无进展生存率为47.7%(95%CI为41.8至53.2),而单独采用纳武单抗治疗为36.0%(95%CI为30.5至41.6)。与单独采用纳武单抗治疗相比,关键亚组的无进展生存期优于瑞拉利单抗-纳武单抗组合治疗。瑞拉利单抗-纳武单抗组合治疗组18.9%的患者和单独纳武单抗治疗组9.7%的患者发生了3级或4级治疗相关不良事件。

由此可见,在既往未经治疗的转移性或无法切除的黑色素瘤患者中,抑制两个免疫检查点LAG-3和PD-1比单独抑制PD-1在无进展生存方面可获得更大的益处。瑞拉利单抗和纳武单抗组合治疗没有新的安全性事件发生。
