Ivonescimab Combined with Chemotherapy As First-line Treatment of Relapsed or Metastatic Thymic Cancer: a Prospective, Single Arm, Phase II Trial

Ivonescimab injection is an IgG1 subtype humanized bispecific antibody targeting human vascular endothelial growth factor-A (VEGF-A) and programmed death protein-1 (PD-1). It can bind to VEGF-A and PD-1 at the same time, and competitively block the interaction between VEGF-A, PD-1 and their ligands, exerting antitumor activity.
