主要研究结果:
• 主要入组标准:≥18岁、ECOG PS 0或1、HER2阴性、3个月FOLFOX/CAPOX后疾病控制的局部晚期不可切除或转移性胃/GEJ癌
• 按1:1的比例随机分为紫杉醇80mg/m2 d1/8/15联合雷莫西尤单抗8mg/kg d1/15 q28d IV(A组)或持续一线含奥沙利铂化疗再12周,随后FU单药维持(B组)
• 分层因素:既往胃切除(否 vs. 是)、腹膜癌(是 vs. 否)、原发肿瘤部位(GEJ vs. 胃)
• 主要终点:PFS(ITT)
• 共纳入280例患者:A/B=144/136;均为白人,男性180例,中位随访43.7个月
• A组与B组的中位PFS分别为6.6与3.5个月(HR=0.61; 95%CI:0.48-0.79; P=0.0002)
• 24个月限制平均生存时间分析:A组与B组的限制平均PFS分别为8.8与6.1个月(P=0.0010)
• A组与B组:
• 最常见的3-4级TRAE为中性粒细胞减少(26/10%)、周围神经病变(6/7%)和动脉高血压(6%/0)
• SAE分别为20%与11%
• 治疗相关各2例;无治疗相关死亡
