ASCO 2014:克唑替尼治疗 c-MET-基因扩增型晚期NSCLC

2014-05-21 佚名 dxy

背景: c-Met基因扩增型NSCLC为非小细胞肺癌的一个亚群,它可能对小分子酪氨酸激酶抑制剂克唑替尼的治疗敏感,该药在多个国家已批准上市,用于治疗晚期ALK阳性非小细胞肺癌。克唑替尼在晚期c-Met基因扩增型NSCLC疗效和安全性数据按照MET/CEP7比例分成三组:≥ 1.8 -≤ 2.2 (低水平组)、 >2.2-<5(中水平组)和≥ 5(高水平组) 。 方法: C- MET扩增

背景: c-Met基因扩增型NSCLC为非小细胞肺癌的一个亚群,它可能对小分子酪氨酸激酶抑制剂克唑替尼的治疗敏感,该药在多个国家已批准上市,用于治疗晚期ALK阳性非小细胞肺癌。克唑替尼在晚期c-Met基因扩增型NSCLC疗效和安全性数据按照MET/CEP7比例分成三组:≥ 1.8 -≤ 2.2 (低水平组)、 >2.2-<5(中水平组)和≥ 5(高水平组) 。

方法: C- MET扩增状况通过FISH测定,每组中分别纳入10-12患者。如果在同一组中有2例或以上的缓解病例,则该组需再增加入组19例。该试验是正在进行的克唑替尼I期临床试验的一部分( NCT00585195 )。患者服用克唑替尼 250mg,每日2次。采用RECIST V1.0评估缓解率。

结果:在数据截止点,共16例患者入组; 3例随后被判定为未达到MET/CEP7扩增标准。13例C-MET基因扩增的NSCLC[其中:低水平(n=1),中水平(n=6)和高水平(n=6)]。入选后以克唑替尼治疗 ,12例可用于疗效评价。

年龄中位数为63岁(范围为42-79岁),92%的患者ECOG 评分为0或1,77 %的人有吸烟史。目前观察到4例的PR( 33% ;95%CI:10.65)其中低水平组(n = 0) ,中水平组(n=1;20%)和高水平组(n=3;50%)。缓解时间中位数为35周[ 95%CI:16,112 ]。治疗时间中位数为15.7周(范围为4 -188周)。

在数据截止点有6例患者仍在治疗中, 5例已经死亡(所有疾病相关)。

16例患者有75 %出现治疗相关不良事件(AEs) :最常见为腹泻(50%)、恶心(31%)、呕吐(31%)、外周水肿(25%)和视力障碍(25%)。大多数不良事件的严重程度为1级。未发生治疗相关的严重不良事件或治疗相关的永久停药。新增的c-Met基因扩增型NSCLC病例正在进行中。

结论:克唑替尼在c-Met基因扩增型NSCLC患者中呈现了抗肿瘤活性,患者普遍能够耐受,而不良事件亦在可接受范围。这些研究结果值得对克唑替尼治疗晚期c -MET扩增型的NSCLC作进一步研究,并探究索MET/CEP7比例与临床获益的相关性。

ASCO 2014:克唑替尼一线治疗晚期ALK阳性非鳞NSCLCIII期临床结果

背景:与标准化疗相比,口服ALK抑制剂-克唑替尼一线治疗晚期ALK阳性非小细胞肺癌的疗效尚不明确。一项多中心、随机、开放标签的III期临床研究评价了克唑替尼比较培美曲塞-铂类化疗( PPC )的疗效与安全性。 方法:试验在2011年1月至2013年7月期间进行,343例初治的晚期非鳞状ALK阳性非小细胞肺癌患者入选,按1:1随机化。 两组患者分别口服克唑替尼250 mg BID(n = 172
