About

A Phase I Clinical Study of CT0181 cells in Patients with Advanced Hepatocellular Carcinoma

Full description

Primary objectives:

Evaluate the safety and tolerance of CT0181 cells in patients with advanced hepatocellular carcinoma within 28 days after the first infusion

Secondary objectives:

Evaluate the metabolic kinetics of CT0181 cells ; Evaluate overall safety and tolerability ; Evaluate the initial efficacy of CT0181 cell infusion in the treatment of advanced hepatocellular carcinoma with positive Glypican-3（GPC3 ）expression.
