Melanoma Res:阿帕替尼联合替莫唑胺治疗免疫治疗失败后的晚期黑色素瘤患者的II期研究

2022-08-03 MedSci原创 MedSci原创

目前,免疫疗法是不可切除或转移性黑色素瘤的标准一线疗法,适用于BRAF突变型或野生型患者。但是,对于免疫治疗进展后的晚期黑色素瘤的治疗是有限的。

目前,免疫疗法是不可切除或转移性黑色素瘤的标准一线疗法,适用于BRAF突变型或野生型患者。但是,对于免疫治疗进展后的晚期黑色素瘤的治疗是有限的。近日,发表于Melanoma Res的一项II期试验(NCT03422445)是为了评估阿帕替尼加替莫唑胺对免疫治疗失败后的晚期黑色素瘤患者的疗效和安全性。

研究纳入免疫治疗进展后不可切除的III期或IV期黑色素瘤患者,在第1-5天接受替莫唑胺300毫克和阿帕替尼500毫克每日每28天周期的治疗,直到疾病进展或出现不可容忍的毒性。除免疫治疗外,允许之前的化疗、靶向治疗和临床试验。主要终点是无进展生存期。次要终点是客观反应率、疾病控制率、总生存期和安全性。

 

结果显示,29名患者中,28名(96.6%)有转移性疾病,主要的亚型是粘膜型[12名(41.4%)]和尖锐湿疣型[8名(27.6%)]。5名(17.2%)患者出现BRAF、CKIT或NRAS突变。5人获得了确认的部分缓解,客观缓解率为17.2%。疾病控制率为82.8%。中位无进展生存期为5.0个月[95%置信区间(CI):4.7-5.3],中位总生存期为10.1个月(95%CI:5.1-15.0)。3-4级治疗相关不良事件包括蛋白尿[4例(13.8%)]、血小板减少[2例(6.9%)]、高血压[1例(3.4%)]和高胆红素血症[1例(3.4%)]。没有发生治疗相关的死亡。

综上所述,该研究结果表明,阿帕替尼加替莫唑胺在免疫治疗进展后的晚期黑色素瘤患者中表现出良好的疗效和可控的安全状况。阿帕替尼联合替莫唑胺可改变肿瘤微环境,可作为免疫治疗进展后的后线治疗方案。
