Official title
A First-In-Human, Phase 1, Open-Label, Multicenter Study of ZW251, a Novel Glypican-3 Targeting Antibody-Drug Conjugate, in Participants With Advanced Solid Tumors, Including Hepatocellular Carcinoma
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), squamous cell non-small cell lung cancer (NSCLC), or germ cell tumors (GCT).
Detailed description
Part 1 (dose escalation) of the study will evaluate the safety and tolerability of ZW251 in HCC, squamous cell NSCLC, and GCT. Part 2 (dose optimization) of the study will further assess safety and potential anti-tumor activity of the ZW251 established recommended doses in HCC.
