Ivonescimab Monotherapy Demonstrates a Statistically Significant & Clinically Meaningful Benefit Compared to Pembrolizumab Monotherapy in PD-L1-Positive Advanced NSCLC in Akeso's HARMONi-2 Study Conducted in China
Summit Therapeutics noted that its partner Akeso will present updated data, including overall survival, from the randomized Phase III HARMONi-2 trial of ivonescimab at the WCLC 2026 conference in Seoul, South Korea. The trial demonstrated a statistically significant and clinically meaningful benefit for ivonescimab monotherapy compared with pembrolizumab monotherapy in PD-L1-positive advanced non-small cell lung cancer patients in China.
Why it matters — SMMT watchers would care because the presentation of positive Phase III data on its partner's investigational bispecific antibody ivonescimab highlights progress for a key asset in the company's pipeline.
