Lung cancer is the No. 1 cancer death rate among Koreans, but treatment is greatly evolving, with the 5-year survival rate more than tripling over 20 years. What had a significant impact on this was the EGFR target treatment.

Targeted treatments targeting EGFR mutations have dramatically improved the overall survival period of patients. Among them, the third generation 'Tagrisso (Osimertinib)' has clearly established itself as a standard treatment for non-small cell lung cancer with current EGFR mutations.

Tagrisso is a third-generation EGFR-TKI that inhibits both EGFR variations and T790M variations represented by L858R and exon 19 deficiencies. It is the only third-generation EGFR-TKI t
