阿卡替尼 vs. 伊布替尼治疗CLL头对头试验达到主要疗效终点

1月25日,阿斯利康官网显示,Calquence(阿卡替尼)治疗既往经治高危慢性淋巴细胞白血病(CLL)成人患者的III期 ELEVATE-RR 研究达到无进展生存期非劣效于伊布替尼的主要终点。

1月25日,阿斯利康官网显示,Calquence(阿卡替尼)治疗既往经治高危慢性淋巴细胞白血病(CLL)成人患者的III期 ELEVATE-RR 研究达到无进展生存期非劣效于伊布替尼的主要终点。ELEVATE-RR研究是首个在CLL患者(成人最常见白血病类型)中开展的头对头比较两种Bruton酪氨酸激酶(BTK)抑制剂疗效的III期临床研究。

该研究同时也达到关键次要终点,与伊布替尼组相比,Calquence组患者房颤不良反应发生率更低(心房纤颤是心律失常的常见类型,房颤患者中风、心力衰竭和其他心脏相关并发症患病风险显着增加)。进一步等级测试结果显示,两组患者3级及以上感染或Richter’s 转化(CLL转变为另一种侵袭性淋巴瘤)发生率无差异。Calquence组OS(总生存期)在数值上有获益趋势。总体而言,Calquence的安全性和耐受性与其此前临床开发项目一致。 ELEVATE-RR(ACE-CL-006)研究是一项随机、多中心、开放标签III期研究,旨在评估Calquence vs 伊布替尼治疗既往接受过治疗的具有高风险特征(存在17p缺失和/或11q缺失)CLL患者疗效。533例受试者被随机分为2组,分别接受Calquence(100mg、每日2次)或伊布替尼(420mg,每日1次)治疗,直至疾病进展或出现不可耐受毒性。 该研究主要终点为独立评审委员会评估的PFS(非劣效性,250个事件测试结果),次要终点包括房颤发生率、治疗相关3级及以上感染发生率、Richter’s 转化发生率和总生存期。 CLL是成人最常见白血病类型,2017年全球估计有11.4万例新发病例。随着治疗方式的改善,CLL患者寿命显着延长。CLL患者血液中过多的骨髓造血干细胞变成了异常的淋巴细胞,而这些异常细胞难以抵抗感染。随着异常细胞数量的增加,健康白细胞、红细胞和血小板的生存空间越来越小,从而导致贫血、感染和出血。 BTK信号的激活是B细胞增殖、转运、趋化和粘附所必需的重要途径之一。Calquence属于新一代BTK选择性抑制剂,可通过与BTK共价结合,抑制其活性。

Calquence于2017年10月首次在美国获批上市,用于治疗套细胞淋巴瘤(MCL),2019年11月,在美国获批2个新适应症,分别用于治疗CLL和小淋巴细胞淋巴瘤(SLL)。2020年11月,Calquence在欧盟获批上市,用于治疗成人CLL。医药魔方NextPharma数据库显示,Calquence 2019年全球销售额为1.64亿美元。

阿卡替尼目前尚未在中国申报上市。

肿瘤学研发执行副总裁JoséBaselga表示:“经过40个月的随访,今天的研究结果证实,选择性BTK抑制剂Calquence在房颤中显示出优越的安全性,且其疗效也非劣效于伊布替尼。该研究的所有数据使williamhill asia 相信,Calquence能够为CLL患者带来更多获益。”
