Lancet:依维莫司还可以治疗癫痫?(EXIST-3)

2016-09-07 Mechront 译 MedSci原创

依维莫司,哺乳动物雷帕霉素靶蛋白(mTOR)抑制剂,已被用于伴结节性硬化症的各种良性肿瘤。我们对结节性硬化症患者进行了研究,比价依维莫司 vs 安慰剂辅助治疗难治性局灶性癫痫发作的有效性和安全性。研究中的依维莫司分为低剂量(3–7 ng/mL)和高剂量组(9–15 ng/mL)。 这项3期、随机、双盲、安慰剂对照研究,从25个国家的99个中心,纳入了2岁–65年的结节性硬化症和难治性癫痫患者

依维莫司,哺乳动物雷帕霉素靶蛋白(mTOR)抑制剂,已被用于伴结节性硬化症的各种良性肿瘤。我们对结节性硬化症患者进行了研究,比价依维莫司 vs 安慰剂辅助治疗难治性局灶性癫痫发作的有效性和安全性。研究中的依维莫司分为低剂量(3–7 ng/mL)和高剂量组(9–15 ng/mL)。

这项3期、随机、双盲、安慰剂对照研究,从25个国家的99个中心,纳入了2岁–65年的结节性硬化症和难治性癫痫患者,服用过一到三种抗癫痫药物。按1:1:1随机分为依维莫司低剂量组(n=117)、高剂量(n=130)组和安慰剂对照组(n=119)。根据年龄进行分层(<6岁,6~<12岁,12~<18岁,≥18岁)。

依维莫司的起始剂量取决于年龄、体表面积,同时使用细胞色素3A4 / P-糖蛋白诱导剂。在6周滴定时间和12周维持期间,为了达到目标值进行剂量调整。患者或他们的照顾者在整个研究期间记录癫痫发作情况。主要终点为维持期癫痫发作频率的变化,定义为反应率(癫痫发作频率减少≥50%),还有癫痫发作频率减少的中位数百分比。

对照组与低剂量组相比,反应率分别为15.1%(95% CI 9.2–22.8; 18名患者)和28.2%(95% CI 20.3–37.3; 33名患者; p=0.0077);与高剂量组相比,高剂量组的反应率为40.0%(95% CI 31.5–49.0; 52名患者; p<0.0001)。

对照组与低剂量组相比,癫痫发作频率减少的中位数百分比分别为14.9% (95% CI 0.1–21.7)和29.3%(95% CI 18.8–41.9; p=0.0028);与高剂量组相比,高剂量组癫痫发作频率减少的中位数百分比为39.6%(95% CI 35.0–48.7; p<0.0001)。

安慰剂组、低剂量组和高剂量组患者的3级或4级不良事件发生情况分别为13 (11%)、21 (18%)和31 (24%)名患者;严重不良事件发生情况分别为 3(3%)、16 (14%)和18 (14%);不良事件导致停药的情况分别为2(2%)、6(5%)和4(3%)。

结果表明,对于伴结节性硬化症的难治性癫痫患者,与安慰剂相比,辅助依维莫司治疗,可显著降低癫痫发作频率,并且耐受性良好。

有研究表明对转移性肾细胞癌 (mRCC)使用三线治疗,疗效尚可。不过该有效性并没有得到很透彻的研究。Stukalin和他的同事进行了一项研究,评估上限治疗方案对mRCC患者的有效性。该研究纳入了 4824名使用过一线治疗方案的患者,其中2534 (52.5%) 的患者接受二线治疗,1060 (22%)的患者接受三线治疗。研究者发现三线治疗里最常用的药物是依维莫司,而该药物也是二线治疗最常用的药物。

NEJM:卡博替尼治疗晚期肾癌效果更佳

卡博替尼是一种口服的小分子酪氨酸激酶抑制剂,能够靶向癌细胞的逃逸机制相关的蛋白如酪氨酸激酶MET和AXL。研究者进行了一项3期试验,比较卡博替尼和依维莫司对经VEGFR靶向治疗后的晚期肾癌患者的疗效。该研究共纳入658名患者,随机分为卡博替尼组(60mg/d)和依维莫司组(10mg/d)。初始结局指标为无进展生存期;继发结局指标为整体生存率和反应率。研究数据显示,卡博替尼组的无进展生存期中位数7.
