A Trial of SHR-1210 (an Anti-PD-1 Inhibitor) in Combination With Apatinib in Patients With Advanced HCC(RESCUE)

A Phase II, Single-arm, Open-label Trial of SHR-1210 (an Anti-PD-1 Inhibitor) in Combination With Apatinib in Patients With Advanced HCC

The purpose of this study is to observe and preliminary explore the efficacy and safety of combination of Apatinib and SHR-1210 regimen in treating advanced hepatocellular carcinoma.

SHR-1210 is a humanized monoclonal antibody against Programmed death 1(PD-1). Apatinib is a new kind of selective Vascular Endothelial Growth Factor Receptor 2(VEGFR-2) tyrosine kinase inhibitor (TKI).

Patients with advanced HCC who failed or intolerable to sorafenib will receive apatinib 250mg orally every day and SHR-1210 200mg (3mg/kg for underweight patients) iv every 2 weeks. The efficacy and safety will be observed.
