多塔利单抗(dostarlimab)是抗PD-1单抗,位列已获批的十个抗PD-1抗体之一[8],2021年获得首批批准[12]。其单药活性在复发性或晚期dMMR子宫内膜癌的I期试验中得以显示[11],随后在原发性晚期或复发性子宫内膜癌的III期双盲随机试验中与化疗联用提示获益[9]。而真正把它与“免除手术”联系起来的,是2022年NEJM报告的II期研究:dMMR II/III期直肠癌患者接受多塔利单抗单药6个月,达到临床完全缓解(cCR)者不再接受化放疗和手术[7]。
本届会上多塔利单抗有两条主要读数。GERCOR-GONO DEWI II期首次中期分析在局部dMMR/MSI-H胃食管腺癌中检验多塔利单抗后观察等待策略,主要终点为1年cCR免手术。现场帖口径并不一致:一说24例可评估患者1年cCR为62.5%(15/24),中位随访16.2个月时达1年cCR者无复发或死亡;一说43例中67.4%(29/43)达1年cCR并保留器官,观察等待的29例无复发或死亡,14/43(32.5%)接受手术,随访14.9个月;另有一帖称25例入组、33%一年时达cCR、1例PD,研究仍在继续。AZUR-1为II期单臂,纳入初治II/III期dMMR/MSI-H直肠癌154例,用药9个周期(6个月):研究者评估的cCR12(完全缓解维持12个月以上且未再治疗)为68%,26%需追加治疗,10%转手术。
主站新闻与现场互为补充。中文报道给出DEWI入组N=60、23例完成12个月评估者中14例达cCR(标题口径为1年cCR率61%),中位随访14.1个月时1年cCR者均无复发或死亡,结论方向与现场一致,但随访月数与患者基数和部分现场帖存在出入,确切数字待确认。监管侧新闻则显示,FDA已于2026年10月19日加速批准Jemperli用于既往未治的II/III期MSI-H/dMMR局部晚期直肠癌成人患者,依据即AZUR-1:新闻称中位随访两年时近四分之三、154例中110例患者免除手术、放疗和化疗;新闻原文并称这是美国用于该人群的首个免疫疗法,2025年全球销售额为11.36亿美元;在中国,该药针对结肠癌、头颈部鳞状细胞癌和非小细胞肺癌的III期研究正在进行,尚未获批上市。
就推进而言,AZUR-1把NEJM单中心队列的观察等待路径推到了154例的全球验证规模[7],DEWI则把器官保留策略从直肠延伸到胃食管腺癌这一新瘤种,直接回应“免疫治疗达到完全缓解后,手术是否仍应是默认选项”的问题。局限同样清楚:DEWI为小样本中期分析,各来源数字尚未统一;AZUR-1单臂、无对照、cCR为研究者评估,新闻亦提示GSK需继续追踪长期获益,DEWI研究也仍在入组随访中。
