Study Of B7H3 CAR-T Cells in Treating Advanced Liver Cancer

Summary

This is single center, open-label phase I/II, non-randomized study which will enroll patients with recurrent advanced hepatocellular carcinoma to evaluate the safety, feasibility, and efficacy of fully human B7H3 CAR-T in treating hepatocellular carcinoma.
