EUR J Cancer:纳米紫杉醇联合雷莫芦单抗治疗胃癌的II期临床研究

2018-02-27 MedSci MedSci原创

纳米粒子白蛋白(nab)结合的紫杉醇被开发用于提高紫杉醇的溶解度,并且不需要预先用药以避免溶剂相关的输注反应。在此研究人员进行了一项II期临床试验,以调查纳米紫杉醇联合雷莫芦单抗治疗晚期胃癌的有效性和安全性。

EUR J Cancer:纳米紫杉醇联合雷莫芦单抗治疗胃癌II临床研究

纳米粒子白蛋白(nab)结合的紫杉醇被开发用于提高紫杉醇的溶解度,并且不需要预先用药以避免溶剂相关的输注反应。在此研究人员进行了一项II临床试验,以调查纳米紫杉醇联合雷莫芦单抗治疗晚期胃癌的有效性和安全性。

对一线化疗方案无效的,且无法进行手术的晚期胃癌患者在第1815天静脉注射纳米紫杉醇(100 mg / m2),在第1天和第15天静脉注射雷莫芦单抗(8 mg / kg)。主要终点为总体反应率(ORR)。次要终点是无进展生存期(PFS),总生存期(OS),疾病控制率(DCR),安全性和生活质量(QOL)。

在接受治疗的43人中, ORR54.8%90%置信区间[CI] 41.0-68.0),符合主要终点。 DCR92.9%95%CI 80.5-98.5),中位PFS7.6个月(95%CI 5.4-8.1)。 与治疗相关的34级不良事件包括中性粒细胞计数减少(76.7%),白细胞计数减少(27.9%),贫血(11.6%),食欲下降(7.0%),发热性中性粒细胞减少(4.7%),高血压4.7%)。没有发生与治疗有关的死亡事件,且研究治疗期间未观察到QOL的恶化。

因此这种联合治疗方案显示出了有效性和可控制的毒性,有望成为先前接受过治疗的晚期胃癌患者的二线治疗选择。
