In a recent late-stage trial, ivonescimab demonstrated a statistically significant improvement in overall survival for patients with squamous non-small-cell lung cancer, extending median survival by four months compared to the standard treatment. This trial, conducted in China, has sparked discussions about the drug's potential applicability to broader populations, as experts like Dr.
