• A phase II trial combining KN046, a bispecific antibody targeting PD-L1/CTLA-4, with lenvatinib achieved a 45.5% objective response rate in advanced hepatocellular carcinoma patients.
• The treatment demonstrated encouraging efficacy with median progression-free survival of 11.0 months and manageable safety profile, though 47.3% of patients experienced grade ≥3 treatment-related adverse events.
• Analysis revealed that circulating tumor DNA status early in treatment may serve as a potential biomarker for predicting treatment response and survival outcomes.
