Efficacy and safety of afatinib in a Chinese population with advanced lung adenocarcinoma with sensitive EGFR mutations

Abstract

Afatinib is an irreversible ErbB family blocker that improves progression‐free survival (PFS) of advanced EGFR‐mutant lung adenocarcinoma compared to chemotherapy. However, afatinib leads to more adverse events than first‐generation EGFR inhibitors. Hence, exploration of the optimal afatinib initial dose and its efficacy and safety in Asian patients has drawn extensive attention.
