New Antibody-Drug conjugate ZW251 enters first human trials for Hard-to-Treat cancers

NCT ID NCT07164313

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This early-stage trial is testing a new drug called ZW251 in about 100 people with advanced solid tumors, including liver cancer (hepatocellular carcinoma), a type of lung cancer (squamous cell non-small cell lung cancer), and germ cell tumors. ZW251 is an antibody-drug conjugate designed to deliver a cancer-killing agent directly to cells that have a protein called glypican-3 on their surface. The main goals are to check the drug's safety and find the right dose.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
ZW251 (an antibody-drug conjugate that targets a protein called glypican-3 on cancer cells)
What this could lead to
If it works, this could point toward a new treatment option for people with advanced liver, lung, or germ cell cancers that have not responded to other therapies.
What could go wrong
This is a very early (Phase 1) trial with only 100 participants, so the drug may not be effective or may cause serious side effects. It is too soon to know if it will help patients.
