High Response Rate Produced by Osimertinib in EGFR T790M-Mutant NSCLC

“Osimertinib (AZD9291), the third-generation TKI, demonstrated a 71% objective response rate (ORR) in those with EGFR T790M-mutant non-small cell lung cancer (NSCLC), following resistance to frontline anti-EGFR therapy, according the findings of the phase II AURA2 trial that was presented at this year’s World Conference on Lung Cancer (WCLC).

“The ORR consisted of 2 complete responses and 139 partial responses. The stable disease rate at ≥6 weeks was 21%, for a disease control rate of 92%. After a median follow-up of 6.7 months, the median progression-free survival (PFS) was 8.6 months. The median duration of response was 7.8 months (27% maturity).”
