曲妥珠单抗作为首个获批的 HER2 靶向单抗,已在 HER2 阳性转移性乳腺癌一线联合化疗[7]、HER2 阳性晚期胃/食管结合部癌一线联合化疗[8]、以及 HER2 阳性早期乳腺癌辅助治疗[12]中确立标准地位;ToGA 研究奠定了胃癌一线标准[8],后续指南将其列为 HER2 阳性晚期胃癌首选靶向药[11]。
ESMO 2026 现场报告了多项扩展 HER2 靶向边界的数据:KC-WISE 双盲 III 期显示,曲妥珠单抗进展后的 HER2 阳性胃/食管结合部癌二线,安贝尼单抗(双特异性双抗)联合化疗对比安慰剂联合化疗,ORR 56% 对 14%,mPFS 7.1 对 2.7 月,mOS 19.6 对 9.7 月(HR 0.39,p<0.0001),G≥3 TEAE 74.2% 对 54.5%[现场帖];HORIZON-Breast06 (LBA13) 报告曲妥珠单抗雷泽泰康 (SHR-A1811) 在 HER2-low 晚期乳腺癌中获益[1];APEX-Breast01 (LBA27) 报告 TQB2102 在 HER2-low 复发/转移乳腺癌中对比化疗的 III 期结果[5];DESTINY-Lung04 患者报告结局显示 T-DXd 肺部症状恶化时间优于化免[现场帖]。
主站新闻同期披露:德曲妥珠单抗 (优赫得®) 于 2026 年 10 月 22 日在中国获批泛瘤种适应症,用于既往治疗或无满意替代方案的不可切除/转移性 HER2 IHC 3+ 成人实体瘤,基于 DESTINY-PanTumor02、DESTINY-Lung01、DESTINY-CRC02、DESTINY-PanTumor03 四项 II 期,属附条件批准[ N1][N3][N5][N7]。
新一代 ADC 与双抗将 HER2 靶向推向 HER2-low 及泛瘤种,但现场专家指出曲妥珠单抗雷泽泰康、TQB2102 等目前仅中国人群数据,缺乏与 T-DXd 的直接对比,且骨髓抑制等毒性权衡仍需长随访明确[现场帖];KC-WISE 对照臂为单药化疗,OS 获益虽大但对照标准非当前最优。

Definitely passes the truck test. No significant OS, likely due to crossover of some patients to TOPO1 ADCs. #ESMO26 #ESMOAmbassadors

Dana-Farber News@DanaFarberNews Elisabetta Bonzano MD, PhD@to_be_elizabeth Yuhei YAMAGUCHI@yymgcmd 引用@🇨🇳 TQB2102 (biparatopic HER2 TOPO1 ADC) also passes the truck test in mostly HR+/HER2-low MBC. PFS 16.4 vs 5.5 mo, HR 0.29, p<0.01. Unclear whether the biparatopic design adds anything. The HER2 TOPO1 field is getting quite crowded with excellent agents. #ESMOAmbassadors #ESMO26

César Serrano García@DrCeSarcoma #ESMO2026 🚨新疗法警报 鉴于可用的回顾性数据很少、疗效令人惊叹,且 #DSRCT 较为罕见,我们可以将 trastuzumab deruxtecan 作为该疾病的标准治疗方案。
