New targeted drug ZV0203 enters first human tests for Hard-to-Treat HER2 cancers

NCT ID NCT05423977

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-stage trial is testing a new drug, ZV0203, in 36 adults with HER2-positive advanced solid tumors that have not responded to standard treatments. ZV0203 is an antibody-drug conjugate designed to deliver a cancer-killing agent directly to HER2-positive tumor cells. The main goals are to check the drug's safety, find the best dose, and see if it shows any signs of shrinking tumors.

What this could mean

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

Active substance
ZV0203 (an antibody-drug conjugate)
What this could lead to
If it works, this could point toward a new treatment option for people with HER2-positive advanced solid tumors that have stopped responding to standard therapies.
What could go wrong
This is a very early Phase 1 trial with only 36 people, focused on safety and dosing. It is too soon to know if ZV0203 will shrink tumors or have serious side effects.
