Overview
The purpose of this study is to find out if ZW251, an antibody-drug conjugate targeting glypican-3 (GPC3), is safe and can treat participants with advanced cancers, including hepatocellular carcinoma (HCC).
Description
Part 1 (dose escalation) of the study will evaluate the safety and tolerability of ZW251 in HCC. Part 2 (dose optimization) of the study will further assess safety and potential anti-tumor activity of the ZW251 established recommended doses in HCC.
