Description

药物组合物及其用途 技术领域
本发明涉及一种含有治疗有效量的伏美替尼或其药学上可接受的盐和任选的药学上可接受的载体的药物组合物。本发明还涉及所述药物组合物用于制备治疗和/或预防由表皮生长因子受体外显子20***(EGFR Exon 20Ins)突变(以下,有时也称为EGFR外显子20***突变)介导的疾病的药物的用途。本发明还提供治疗和/或预防由EGFR外显子20***突变介导的疾病的方法,其中给予患者治疗有效量的伏美替尼或其药学上可接受的盐。
背景技术
在世界范围内,肺癌一直是发病率和死亡率最高且严重危害人类健康和生命的恶性肿瘤,2018年全球176万人死于肺癌。非小细胞肺癌(NSCLC)约占所有肺癌的80-85%。表皮生长因子受体(EGFR)突变是NSCLC中研究最广泛的靶点;EGFR突变在西方和亚洲NSCLC患者中分别占17%和50%。在EGFR基因突变中,常见敏感突变为19外显子缺失和21外显子的点突变(L858R),占所有EGFR突变的85%-90%。EGFR外显子20***突变(EGFR Exon 20Ins)为EGFR突变中的另一大类突变,约占所有EGFR突变类型的1-10%,占全部NSCLC患者的1-2%。这些***突变是异质的,且发生在762和774之间的多个氨基酸位置,导致***1-7个氨基酸,其中部分为局部复制。迄今为止,已发现122种EGFR外显子20***突变,最常见的亚型是D770-N771insX突变(25.5%)、V769-D770insX突变(24.6%)和H773-V774insX突变(22.6%)。
多年来针对NSCLC中EGFR突变研发出了大量的靶向药,比如针对EGFR敏感突变的一代可逆性的酪氨酸酶抑制剂(TKI)吉非替尼和厄洛替尼,二代不可逆共价结合抑制剂阿法替尼,以及针对耐药突变EGFR T790M的三代抑制剂奥希替尼,均有非常好的临床效果。但一代或二代EGFR-TKI对EGFR外显子20***突变治疗基本无效。另外,与典型的EGFR敏感突变、T790M耐药突变不同,EGFR外显子20***突变对FDA批准的所有EGFR-TKI(包括奥希替尼)的应答均较差。
针对EGFR外显子20***突变的EGFR抑制剂目前也已进入临床开发阶段,如波奇替尼、TAK-788(Mobocertinib)等,在临床试验中显示出潜在疗效。尽管这些药物显示了一定的疗效,但疗效有限,这提示在EGFR外显子20***突变疗效提升方面有待更多的研究探索。目前全球尚无针对EGFR外显子20***突变的小分子靶向药物被批准,因此存在巨大临床需求。
在本申请人的专利CN105315259B中记载下式(I)所示的N-{2-{[2-(二甲胺基)乙基](甲基)胺基}-6-(2,2,2-三氟乙氧基)-5-{[4-(1-甲基-1H-吲哚-3-基)嘧啶-2-基]胺基}吡啶-3-基}丙烯酰胺(也称作“伏美替尼”),在本申请人的专利CN107163026B中记载了下式(I)化合物的甲磺酸盐(也称作“甲磺酸伏美替尼”),甲磺酸伏美替尼作为第三代EGFR-TKI抑制剂已经商业化,主要用于治疗由EGFR敏感突变、T790M耐药突变介导的疾病。甲磺酸伏美替尼的I期爬坡试验已经证实了甲磺酸伏美替尼在20mg-240mg剂量水平下,每日口服1次,耐受性和安全性良好,受试者发生的不良事件均为轻度或中度,未出现剂量限制性毒性,未出现与剂量相关的毒性反应;II b期临床试验已经证实了80mg日剂量口服给药甲磺酸伏美替尼时,对治疗后进展的EGFR T790M阳性晚期非小细胞肺癌患者具有较好的抗肿瘤作用,能缓解或稳定疾病的进程。
