BR.26的title是PF-00299804 in Treating Patients With Stage IIIB or Stage IV Non-Small Cell Lung Cancer That Has Not Responded to Standard Therapy for Advanced or Metastatic Cancer
对于这个“Not Responded”的判断准则是:
Previous Therapy Failure of a treatment regimen is defined as the inability to continue a regimen for any reason including, but not limited to, progressive disease, toxicity, or patient request. Up to a maximum of three lines of chemotherapy for advanced/metastatic disease (defined below) and at least one of erlotinib or gefitinib for advanced/ metastatic disease (defined below) should have failed.
最多三线的化疗失败以及最少一线的靶向(易/特)失败,参照NCCN 2014v1的Guideline,三线以后PS0-2分的患者可选的治疗方案就只有BSC和clinical trials了,2992之前也开过多线之后的临床(LUX-Lung1),说明FDA的伦理委员会对多线治疗失败之后的患者加入安慰剂控制的临床试验组是认同的。
PS:2992的LUX-Lung1的结果也表明多线之后特别是对EGFR TKI耐药之后的患者再用同一靶点的药效果都不佳
