Brief Summary

TQB2223 is a recombinant, fully human antibody that binds to lymphocyte activation gene-3 (LAG-3) and blocks the LAG-3/ major histocompatibility complex class II (MHC-II) interaction, thus allowing for increased T-cell proliferation and cytokine production. This is a phase Ib study aimed at evaluating the safety, tolerability, and immunogenicity characteristics of TQB2223 injection combined with AK105 injection in the treatment of advanced hepatocellular carcinoma.
