乐伐替尼可有效治疗中国放射性碘难治性分化型甲状腺癌患者

在多国家3期SELECT研究中,乐伐替尼(Lenvatinib)显示出了有效治疗放射性碘难治性分化型甲状腺癌 (RR-DTC) 的疗效;但是,乐伐替尼在中国RR-DTC患者中的疗效尚未进行过验证。近年数据提示,中国大约有19.4万确诊的甲状腺癌患者。

本研究旨在评估乐伐替尼用于中国RR-DTC患者中的疗效和安全性

招募了确诊为RR-DTC的中国患者(n=151),以 2:1 的比例随机分成了两组,接受乐伐替尼 (24 mg/天,n=103) 或安慰剂(n=48)治疗,每28天为一个疗程。主要终点是无进展生存期(PFS);关键的次要终点包括客观缓解率和安全性。

两组患者的无进展生存期

乐伐替尼组的无进展生存期显著长于安慰剂组(中位PFS:23.9 vs 3.7 个月;风险比[HR] 0.16, 95%CI 0.10-0.26;p<0.0001)。乐伐替尼组和安慰剂组的客观缓解率分别是69.9%和0%

在数据截止时,乐伐替尼组60.2%的患者仍在接受治疗;治疗中出现的不良事件导致8.7%的患者停用乐伐替尼。总体上,乐伐替尼组87.4%的患者发生了3级及以上的需紧急治疗的不良事件,最常见的有高血压(62.1%)和蛋白尿(23.3%)。

综上,与安慰剂相比,乐伐替尼(24 mg/天)也可显著提高中国 RR-DTC 患者的无进展生存期和客观缓解率。没有新发生的或意外的毒性。该研究结果与SELECT研究的结果一致。
