Ivonescimab Demonstrates Significant First-Line Advantage in NSCLC at ESMO 2025
In a highly anticipated first-line study presented at ESMO 2025, the bispecific antibody Ivonescimab (PD-1×VEGF) developed by Akeso Biopharma and Summit Therapeutics achieved a 40% reduction in risk of disease progression or death compared to the PD-1 inhibitor Tislelizumab (brand name Tevimbra) plus chemotherapy in previously untreated squamous non-small-cell lung cancer (NSCLC) in the HARMONi-6 trial.
The trial, conducted in a Chinese patient population, showed a median progression-free survival (PFS) of 11.1 months with Ivonescimab plus chemotherapy, compared to 6.9 months with Tislelizumab plus chemotherapy, reflecting an improvement of around 4.2 months. In patients with PD-L1 expression below 1%, Ivonescimab achieved a 45% increase in median PFS, indicating potential efficacy across a wide range of biomarker profiles.
While overall-survival (OS) data remain immature, the companies expressed optimism given a durable median duration of response of 11.2 months with Ivonescimab versus 8.4 months with Tislelizumab. A separate ongoing global trial, HARMONi-3, is comparing Ivonescimab to the market-leading Pembrolizumab (Keytruda) in both squamous and non-squamous NSCLC and will include ex-China populations, with squamous read‐out expected next year and non-squamous in 2027.
