EJC:培美曲塞+埃罗替尼可改善非鳞状NSCLC生存

2014-06-20 2005013036 丁香园

培美曲塞和埃罗替尼已被批准用于局部晚期或转移性非小细胞肺癌(NSCLC)患者二线治疗。美国礼来公司进行了一项多中心、随机、非盲、平行的II期临床试验,对培美曲塞单药及培美曲塞联合埃罗替尼用于非鳞状NSCLC患者治疗的疗效和安全性进行了评估,并于2014年4月将研究结果在线发表于《欧洲癌症杂志》(EJC)。患者入组标准为含有1处或1处以上经实体瘤疗效评价标准(RECIST)评估为可测量病灶,且美国东

培美曲塞和埃罗替尼已被批准用于局部晚期或转移性非小细胞肺癌(NSCLC)患者二线治疗。美国礼来公司进行了一项多中心、随机、非盲、平行的II期临床试验,对培美曲塞单药及培美曲塞联合埃罗替尼用于非鳞状NSCLC患者治疗的疗效和安全性进行了评估,并于2014年4月将研究结果在线发表于《欧洲癌症杂志》(EJC)。


患者入组标准为含有1处或1处以上经实体瘤疗效评价标准(RECIST)评估为可测量病灶,且美国东部肿瘤协作组(ECOG)体能评分≤2的,以铂为基础的化疗失败的III-IV期NSCLC患者。主要研究终点为无进展生存期(PFS)。次要研究终点包括总生存期(OS)、治疗失败时间(TTTF)、治疗响应率及毒性。中位随访时间为27个月。

从2007年4月起,研究共招募159例非鳞状NSCLC患者并随机进行分组,83例患者接受培美曲塞单药治疗,83例接受培美曲塞及埃罗替尼联合治疗。培美曲塞单药治疗组中位总生存期为7.75个月,培美曲塞及埃罗替尼联合治疗组为11.83个月,风险比为0.68。

培美曲塞及埃罗替尼联合治疗组中1例患者死于发热性中性粒细胞减少。培美曲塞或培美曲塞联合埃罗替尼治疗组患者3/4级药物相关毒性分别为:发热性中性粒细胞减少(2.4%/10.5%)、腹泻(1.2%/5.3%)、皮疹(1.2%/9.2%)、贫血(6%/11.8%)、白血球减少症(9.6%/23.7%)、中性粒细胞减少(9.6%/25.0%)、血小板减少(4.8%/14.5%)。

研究人员得出结论,与培美曲塞单药治疗相比,培美曲塞联合埃罗替尼用于非鳞状NSCLC患者2线治疗可显著延长患者无进展生存期、总生存期、治疗失败时间,但也增加了患者3/4级毒性。临床信息:NCT00447057。
