Phase III Trials Test First-Line Options in Advanced NSCLC

Presented at the 2026 World Conference on Lung Cancer, two phase III trials-PAPILLON and REZILIENT3-established amivantamab and zipalertinib combination therapies as effective first-line strategies for advanced NSCLC with EGFR exon 20 insertions, with significantly improved progression-free survival, although high crossover rates prevented them demonstrating an overall survival benefit. Separately, HARMONi-2 showed that the bispecific antibody ivonescimab improved overall survival versus pembrolizumab in PD-L1-positive NSCLC, supporting its use as standard of care in China while larger global trials continue.
