Experimental Note Identified from the Human Clinical Data
Experiment for
Molecule Alteration		 Sanger sequencing assay; Fluorescence in situ hybridization assay; Real-time polymerase chain reaction assay; Targeted exome sequencing assay
Experiment for
Drug Resistance		 Computed tomography assay
Mechanism Description Acquired resistance mechanisms of AZD9291 in patients with EGFRT790M-mutant NSCLC who failed treatment with first-generation EGFR TkIs include the loss of EGFRT790M-mutant clones plus alternative pathway activation or histologic transformation and EGFR ligand-dependent activation.
