Ivonescimab (依达方®) is a first-in-class, humanized, tetravalent bispecific monoclonal antibody targeting programmed cell death protein 1 (PD-1) and vascular endothelial growth factor (VEGF)-A being developed by Akeso Biopharma for the treatment of non-small cell lung cancer (NSCLC) and other solid tumours, including breast cancer, liver cancer and gastric cancer. Ivonescimab simultaneously blocks the binding of PD-1 to its ligand (PD-L1), thereby relieving PD-1/PD-L1-mediated immunosuppression, and blocks the binding of VEGF-A to its receptor (VEGFR2), thus blocking tumour angiogenesis in the tumour microenvironment. In May 2024, ivonescimab, in combination with pemetrexed and carboplatin, received its first approval in China for the treatment of patients with EGFR-mutated locally advanced or metastatic non-squamous NSCLC who have progressed after tyrosine kinase inhibitor (TKI) therapy. Clinical studies of ivonescimab are underway in multiple countries worldwide. This article summarizes the milestones in the development of ivonescimab leading to this first approval for EGFR-mutated locally advanced or metastatic non-squamous NSCLC who have progressed after TKI therapy.
