Summary
Advanced pancreatic cancer is a highly aggressive and fatal disease with an extremely low 5-year survival rate. Combined chemotherapy is the mainstay of treatment for patients with unresectable advanced pancreatic cancer, and the combination of nab-paclitaxel and gemcitabine (AG regimen) has been one of the most commonly used regimens for more than a decade. However, chemo-resistance often occurs within half a year and the efficacy remains unsatisfied with an overall survival of only 9\~11 months. Immune checkpoint inhibitors (ICIs) such as anti-PD-1/L1 antibody and anti-CTLA-4 antibody have demonstrated encouraging anti-tumor efficacy in multiple solid tumors including lung cancer, gastric cancer, and esophageal cancer, while obtained controversial results when combined with chemotherapy in pancreatic cancer. Recently, the immune-suppression tumor microenvironment (TME) of pancreatic cancer has been described in several pre-clinical studies, which may explain the resistance against ICIs and chemotherapy. KN046 is a recombinant humanized PD-L1/CTLA-4 bispecific antibody with innovative designs include a proprietary CTLA-4 domain antibody with a significantly improved safety profile, a bispecific antibody fused with PD-L1 antibody targeting the TME with high PD-L1 expression. Recent clinical studies have shown promising anti-tumor activity of KN046 in pancreatic cancer. Surufatinib, also known as HMPL-012 or Sulfatinib, is a small molecular tyrosine kinase inhibitor (TKI) targeting the Vascular Endothelial Growth Factor Receptor (VEGFR), Fibroblast Growth Factor Receptor (FGFR) and Colony Stimulating Factor-1 Receptor (CSF-1R), which has a dual mechanism of action of anti-angiogenesis and regulation of immune microenvironment. Previous studies have suggested synergic effect of surufatinib in combination with anti-PD-1 antibodies. This phase Ib/II clinical trial is intended to investigate the activity and safety of the combination of surufatinib combined with KN046 and the AG regimen chemotherapy as first-line treatment in patients with unresectable locally advanced or metastatic pancreatic cancer.
