Durvalumab and Lenvatinib in Participants With Locally Advanced and Metastatic Hepatocellular Carcinoma ( Dulect2020-1 )

This study will evaluate the safety and efficacy of durvalumab in combination with lenvatinib in participants with locally advanced hepatocellular carcinoma before liver transplant and metastatic unresectable HCC.The primary hypothesis of this study are that patients with locally advanced HCC could benefit from durvalumab plus lenvatinib before liver transplant; patients with metastatic unresectable HCC could also benefit from durvalumab plus lenvatinib with respect to: 1)Progression Free Survival (PFS) ; or recurrence-free survival (RFS) if patients with locally advanced HCC underwent liver transplant; 2) Objective Response Rate (ORR); and 3) Overall survival (OS). The investigators design a clinical study to explore whether the combination above as a treatment in patients with advanced and recurrent endometrial carcinoma could prolong PFS and to analyze potential immune biomarker of therapeutic response.

The combination of Lenvatinib and Programmed death-ligand 1 (PD-L1) blocking has great potential in the treatment of locally advanced hepatocellular carcinoma before liver transplant and metastatic unresectable HCC. This trial is designed as a prospective, open label study for 20 patients with locally advanced hepatocellular carcinoma before liver transplant and metastatic unresectable HCC. The aim is to investigate the efficacy of the combination therapy of Lenvatinib 80-120mg daily orally and durvalumab 1500mg by IV infusion every 4 weeks in terms of progression free survival.
