About

This is a phase II, open-label study to evaluate the efficacy and safety of Durvalumab plus Lenvatinib as first-line treatment in patients with unresectable hepatocellular carcinoma.

Full description

This single-arm, open-label, prospective phase II clinical trial was designed to evaluate the efficacy and safety of Durvalumab plus Lenvatinib as first-line treatment in patients with unresectable hepatocellular carcinoma. The primary endpoint is the objective response rate (ORR) according to RECIST v1.1. Safety evaluation will be taken according to CTCAE v5.0. Disease control rate (DCR), duration of response (DOR), progression-free survival (PFS) and overall survival (OS) are secondary endpoints. Multi-omics analysis will be performed to identify potential biomarkers for treatment response.

Enrollment: 25 estimated patients

Sex: All

Ages: 18 to 80 years old

Volunteers: No Healthy Volunteers
