J Clin Oncol:纳武单抗联合伊匹单抗用作广泛性疾病小细胞肺癌维持疗法

2021-03-09 MedSci原创 MedSci原创

在广泛性疾病小细胞肺癌(ED-SCLC)中,以铂为基础的一线化疗的有效率很高,但疗效缺乏持久性。

在广泛性疾病小细胞肺癌(ED-SCLC)中,以铂为基础的一线化疗的有效率很高,但疗效缺乏持久性。CheckMate 451试验是一项双盲的III期试验,评估了纳武单抗联合伊匹单抗对比纳武单抗单一疗法作为ED-SCLC一线化疗后的维持疗法的疗效和安全性。

招募了东方合作肿瘤组评分0~1分、一线化疗≤4个疗程后无进展的ED-SCLC患者,随机分成了两组,联合组给予纳武单抗1 mg/kg+伊匹单抗 3 mg/kg,每3周1次,共12周,随后给予纳武单抗240 mg,每2周1次;单药组给予纳武单抗 240 mg,每2周1次,或安慰剂治疗≤2年或直至病情进展或出现不可接受的毒性反应。主要终点是总生存期(OS)。

各组的OS

总体上,共834名患者被随机分组。最短随访时间为8.9个月。与安慰剂相比,使用纳武单抗联合伊匹单抗治疗的患者的OS没有显著延长(风险比[HR] 0.92;95%CI,0.75-1.12;p=0.37;中位数 9.2 vs 9.6个月)。使用纳武单抗维持治疗的患者的中位OS为10.4个月,与安慰剂相比的HR为0.84(95%CI 0.69-1.02)。

各预定亚组分析的OS

与安慰剂相比,纳武单抗联合伊匹单抗治疗的患者的无进展生存率的HR为0.72(95%CI 0.60-0.87),纳武单抗单药治疗的HR为0.67(95%CI 0.56-0.81)。

根据TMB值分层的患者OS

在肿瘤突变负荷(TMB)为≥13个突变/MB的患者中,观察到纳武单抗和伊匹单抗联合应用对OS有利的趋势。

三组方案组中与治疗相关的3-4级不良事件发生率分别为52.2%(联合组)、11.5%(单药组)和8.4%(安慰剂组)。

综上,对于一线化疗后没有进展的ED-SCLC患者,纳武单抗联合伊匹单抗维持治疗不能延长其OS。
