Clin Cancer Res:帕博西利联合曲妥珠单抗治疗HER2+晚期乳腺癌的疗效

2020-09-17 MedSci原创 MedSci原创

本研究(PATRICIA)旨在评估Palbociclib(帕博西尼)联合曲妥珠单抗和或无内分泌治疗用于HER2阳性(+)晚期乳腺癌。

本研究(PATRICIA研究)旨在评估Palbociclib(帕博西利)联合曲妥珠单抗和或无内分泌治疗用于HER2阳性(+)晚期乳腺癌

该研究是一项前瞻性的、开放标签的、多中心II期试验,招募既往接受过2-4线以抗HER2为基础的方案治疗的晚期乳腺癌患者。予以帕博西利(200 mg/日,连用2周,停1周)联合曲妥珠单抗治疗。该研究是基于一个包含3个队列的Simon两阶段设计:雌激素受体(ER)阴性(A队列)、ER阳性(B1队列)和ER阳性+来曲唑(B2队列)。ER阳性患者被随机分至B1队列或B2队列。主要终点是6个月时的无进展存活率(PFS6)。次要终点包括安全性和PAM50内在亚型的评估。

共招募了71位患者(A队列 15位、B1和B2队列各28位)。A、B1和B2队列的PFS6分别为33.3%(5/15)、42.8%(12/28)和46.4%(13/28)。安全性方面:1-2级和3-4级毒性反应分别发生于97.7%和84.4%的患者。最常见的3-4级毒性反应有中性粒细胞减少(66.4%)和血小板减少(11.3%)。59例(83.1%)肿瘤被纳入PAM50分析:Luminal亚型与更长的无进展存活期独立相关,luminal亚型 vs 非-luminal亚型的中位PFS分别是10.6 vs 4.2个月(校正风险比 0.40,p=0.003)。

综上所述,帕博西利联合曲妥珠单抗用于既往治疗过的ER阳性/HER2阳性的PAM50 luminal A或B亚型晚期乳腺癌患者的存活预后良好,而且耐受性高。
