Osimertinib for lung cancer cells harboring low-frequency EGFR T790M mutation

Excerpt:
NGS and allele-specific PCR confirmed the low-allele frequency of EGFR T790M present at 5% with a 100-fold higher resistance to erlotinib in the PC-9R cells and its sub-clones….Consistent with in vitro data, osimertinib, but not erlotinib, caused tumor regression in mice injected with PC-9R cells, while both osimertinib and erlotinib inhibited tumors in mice injected with PC-9 cells...allele-specific PCR confirmed the presence of EGFR T790M mutation in PC-9R cells (Fig. 2C)....In accordance with the in vitro data and literature supporting the higher efficacy of osimertinib, both the PC-9 and PC-9R mice showed remarkable responses to daily osimertinib treatment.
