Andamertinib (®) is a tyrosine kinase inhibitor (TKI) of epidermal growth factor receptor (EGFR) being developed by Beijing Avistone Biotechnology for the treatment of non-small cell lung cancer (NSCLC). On 30 April 2026, andamertinib received conditional approval in China for adult patients with locally advanced or metastatic NSCLC who have experienced disease progression during or following platinum-based chemotherapy, or who are intolerant to platinum-based chemotherapy, and who have been confirmed by testing to have an EGFR exon 20 insertion mutation. This article summarizes the milestones in the development of andamertinib leading to this first approval for NSCLC.
