• The approval of ivonescimab in China as a monotherapy for first-line NSCLC with positive PD-L1 expression positions it as a competitor to pembrolizumab in that market, based on the results of the HARMONi-2 trial.
• The ongoing Phase III trials, HARMONi-3 and HARMONi-7, are designed to evaluate ivonescimab against pembrolizumab-based regimens in different NSCLC patient populations, which will further define its competitive positioning.
