Official title

A Multicenter, Open-label, Single-Arm Phase I/II Clinical Study to Evaluate the Safety and Efficacy of a Single Dose of MDN-001 Injection in Patients With Unresectable Primary Hepatocellular Carcinoma (HCC).

Overview

The main purpose of the study is to evaluate the safety and efficacy of MDN-001 injection(Yttrium-90 Microsphere Injection)in the treatment of unresectable hepatocellular carcinoma.
