Report Summary
UBS presents a bull/bear debate on Summit Therapeutics (SMMT), focused on ivonescimab, a first-in-class PD-1xVEGF bispecific that was the first drug in history to beat Keytruda head-to-head in a Phase 3 randomized trial in 1L PD-L1+ NSCLC. The bull case centers on demonstrated OS benefits in HARMONi-6 (34% reduction in risk of death vs. tislelimab+chemo in 1L squamous NSCLC) and the expectation that HARMONi-3 will translate these benefits. The bear case questions subgroup imbalances and the ability to replicate China trial results in global populations.
