This is a single center, single arm, open-label, phase I study to evaluate the safety and efficacy of GPC3-CAR-T cells in patients with hepatocellular carcinoma.

GPC3-CAR-T cells is a novel CAR-T cells which designed for the cell membrane protein Glypican-3. Patients with hepatocellular carcinoma will be enrolled, and GPC3-CAR-T cells will be intravenously infused with a escalated dose of 1×106, 3×106, 10×106 GPC3-CAR-T cells. Tumor markers and GPC3-CAR-T cell proliferation will be monitored in the scheduled time (day 0, day 4, day 7, day 10, day 14, day 28). The aim of this clinical trial is to evaluate the safety and efficacy of GPC3-CAR-T cells therapy in patients with hepatocellular carcinoma. The primary endpoint is the safety of CAR-T cells including the effect ratio of CRS and ICANS, ORR. The secondary endpoint is the CAR-T ratio and CAR gene copied number in PB, PFS, OS and DOR.
