CheckMate-078研究:首次印证免疫治疗在中国人群的疗效和安全性

2018-07-13 佚名 肿瘤资讯

CheckMate-078研究是第一项针对东亚人群,特别以中国人群为主的免疫检查点抑制剂二线治疗晚期NSCLC的临床研究。与纳武利尤单抗(Nivolumab)在全球注册临床CheckMate-017研究和CheckMate-057研究结果一致,在CheckMate-078研究中,纳武利尤单抗对比化疗显著降低患者的死亡风险。该研究成功的进一步验证了纳武利尤单抗的卓越疗效和安全性。基于CheckMat


CheckMate-078研究是第一项针对东亚人群,特别以中国人群为主的免疫检查点抑制剂二线治疗晚期NSCLC临床研究。与纳武利尤单抗(Nivolumab)在全球注册临床CheckMate-017研究和CheckMate-057研究结果一致,在CheckMate-078研究中,纳武利尤单抗对比化疗显著降低患者的死亡风险。该研究成功的进一步验证了纳武利尤单抗的卓越疗效和安全性。基于CheckMate-078研究的结果,纳武利尤单抗获批用于EGFR和ALK阴性、既往接受过含铂方案化疗后疾病进展或不可耐受的局部晚期或转移性NSCLC成人患者,使免疫治疗真正在中国落地。

CheckMate-078研究背景

多中心、随机III期研究CheckMate-078在含铂双药化疗治疗后出现疾病进展的IIIb/IV期EGFR阴性和ALK阴性的NSCLC患者中,比较纳武利尤单抗与多西他赛的疗效和安全性。该研究主要在中国患者(n=451)中进行,同时入组少量俄罗斯(n=45)和新加坡(n=8)患者。研究不限制患者的病理类型,共入组鳞癌或非鳞NSCLC患者504例,2:1随机分配接受纳武利尤单抗(n=338)或多西他赛(n=166)治疗。具体给药方案为每2周纳武利尤单抗3 mg/kg或每3周多西他赛75 mg/m2,治疗至疾病进展或发生不可耐受的毒性。主要研究终点为总生存期。

CheckMate-078研究结果解读

CheckMate-078研究结果首次在2018 AACR年会上公布,由吴一龙教授做口头报道,这是中国专家在AACR大会上的第一个临床口头报告。研究达到主要终点:纳武利尤单抗对比多西他赛,显著延长患者的总生存,两组的中位总生存期分别为12.0和9.6个月,纳武利尤单抗较多西他赛降低了32%的死亡风险(图1,HR 0.68,97.7% CI:0.52-0.90;P=0.0006),1年总生存率分别为50%和39% 。

亚组分析显示,在不同组织学类型和PD-L1表达水平的患者中均观察到纳武利尤单抗带来的OS获益。与多西他赛相比,在鳞癌患者中,OS HR为0.61(95% CI:0.42-0.89);在非鳞癌患者中,OS HR为0.76(95% CI:0.56-1.04)。在PD-L1表达水平<1%和≥1%的患者中,OS HR分别为0.75(95% CI:0.52-1.09)和0.62(95% CI:0.45-0.87)。无论患者的组织学类型和PD-L1表达状态,CheckMate 078研究的结果都与全球研究CheckMate017和CheckMate057结果一致。

次要研究终点评估,如ORR(客观缓解率)、mDoR(中位缓解持续时间)、PFS(无进展生存率)对比,纳武利尤单抗亦优于多西他赛,两组的ORR分别为17%和4%;mDoR分别为尚未达到和5.3个月;两组虽然中位PFS均为2.8个月,但PFS曲线在3个月后开始分离,与化疗相比,纳武利尤单抗显著降低23%的疾病进展或死亡风险(HR 0.77,95% CI:0.62-0.95;P=0.0147)。安全性分析显示,纳武利尤单抗用于亚洲人群的安全性良好,3-4级治疗相关不良事件发生率低于多西他赛组(分别为10%和47%)。

关键信息

CheckMate-078研究证实,与纳武利尤单抗在全球注册研究CheckMate 017和CheckMate 057的研究结果一致,纳武利尤单抗的获益和安全性无种族差异。在经治晚期NSCLC患者中,纳武利尤单抗对比化疗显著改善多项研究终点,包括OS及ORR、mDOR、PFS。纳武利尤单抗对比化疗显示出显著的生存获益,mOS分别为12.0和9.6个月(HR 0.68, 97.7% CI :0.52-0.90)。在有效率方面,纳武利尤单抗二线治疗西方NSCLC患者的ORR为 19%~20%,治疗东方人群的ORR为17%,在数值上几乎无差异。

综上总结

CheckMate-078研究是第一个以中国人群为主的免疫检查点抑制剂的临床研究并公布结果。从研究结果来看,CheckMate-078研究进一步验证了纳武利尤单抗的卓越疗效和安全性。根据CheckMate-078研究的研究结果,中国药品监督管理局于2018年6月15日批准了纳武利尤单抗应用于临床,标志着中国晚期NSCLC迈入免疫治疗新时代,在晚期NSCLC的二线治疗上完全有可能做到“chemo-free”。

Nature:肿瘤中存在大量与癌症不相关的“吃瓜”杀伤性T细胞,难怪有些患者对免疫治疗没反应

免疫治疗,尤其是免疫检查点抑制剂治疗,可以有效恢复T细胞消灭癌细胞的能力,从而给患者带来显着和持续的临床反应。不过,越来越多的研究证明,仅有一部分患者能从治疗中获益,大部分患者对这种疗法还是不响应。

肿瘤免疫治疗和提高人体免疫力有没有关系?

问:免疫治疗和提高免疫力有关吗?答:肿瘤免疫治疗主要是就将自身不平衡、失衡的免疫系统纠正过来,而不是说可以无限提升人体的免疫力。免疫肿瘤治疗药物获批,让很多患者看到了新的希望。然而,大众对于免疫治疗存在着误解,也抱着太大的期望。免疫治疗就是癌症的克星?只要用上免疫治疗就一定能“药到病除”?广东省人民医院终身主任吴一龙教授告诉澎湃新闻(www.thepaper.cn),中国人对“免疫”这个词特别敏

Cell Stem Cell:比CAR-T更安全!CAR-NK疗法初显成效

2017年,美国FDA先后批准两款CAR-T细胞疗法,推进了这一代表性免疫疗法的快速发展。除了“小车”CAR(嵌合抗原受体)的选择之外,科学家们开始思考免疫细胞的获得。最新一项研究提出一种可能:利用人类诱导性多能干细胞(iPSCs)获得的自然杀伤细胞(NK)经过类似的修饰之后,同样可以呈现出高效的抗癌活性。

JCO:免疫治疗疗效评价标准imRECIST

美国Dana-Farber癌症研究所Hodi等报告,免疫治疗疗效评价标准(imRECIST)除了通过靶病灶来判断疾病进展(PD)状态外,还通过对无进展生存期(PFS)的评估,以及对疾病进展模式的分析,可以更好地识别出患者在总体生存率上的获益程度。上述结果或可用于修订疗效评价的影像学标准,以便更好地反映肿瘤免疫治疗的疗效。(J Clin Oncol. 2018年1月17日在线版 doi: 10.12

变应性鼻炎都可以免疫治疗吗?

问:是不是只要是变应性鼻炎就可以免疫治疗呢?答:不是的。过敏性鼻炎,医生也称变应性鼻炎(简称AR),咱老百姓就简称“鼻炎”。是特应性个体接触变应原后由IgE介导的鼻黏膜炎症反应性疾病。简单点来说就是容易过敏的人,接触了导致你过敏的东西后,引起了鼻子的不舒服的反应。这些不舒服的反应主要包括反复喷嚏、流清水样的鼻涕、鼻塞和鼻痒,有时候有眼痒、结膜充血和/或流泪。最新的研究表明过敏性鼻炎在我国大陆地区

Cell Rep:大开眼界!肿瘤细胞竟是这样躲过免疫治疗的!

目前,以PD-1/PD-L1抑制剂为主的免疫疗法已成为肿瘤治疗领域的绝对热门,但是,PD-1 /PD-L1抑制剂在不同类型肿瘤病人中应用后,其效果却因人而异。科学家们曾认为这是受制于患者肿瘤细胞PD-L1的表达水平,然而,随着对PD-1 /PD-L1抑制剂疗法的深入研究,研究人员发现部分患者即使表达了高水平的PD-L1,PD-1 /PD-L1抑制剂仍无法有效治疗肿瘤。这是为什么呢?
