A Phase I/II study to evaluate AZD5851 in patients with GPC3+ advanced/recurrent hepatocellular carcinoma.

Official Title

A Phase I/II Open-Label Study to Evaluate the Safety, Cellular Kinetics and Efficacy of AZD5851, a Chimeric Antigen Receptor T-Cell (CAR-T) Therapy Directed Against GPC3 in Adult Participants With Advanced/Recurrent Hepatocellular Carcinoma: ATHENA


This first-time in human, single-arm, open-label multicentre Phase I/II study will evaluate the safety, tolerability, antitumour activity, cellular kinetics, pharmacodynamics, and immunogenicity of AZD5851 in adult participants with GPC3+ advanced/recurrent HCC, where at least one line of prior therapy has failed/or was intolerable, or participant/investigator decision.
