First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This early-stage trial is testing a new drug called ESG406 in 556 adults with advanced or metastatic solid tumors that have not responded to standard treatments. The study will first find a safe dose, then expand to see if the drug can shrink tumors. The main focus is on safety and tolerability, with tumor response as a secondary goal.

What this could mean

Active substance

ESG406 (a drug given by IV infusion)

What this could lead to

If it works, this could point toward a new treatment option for people with advanced solid tumors that have stopped responding to standard therapies.

What could go wrong

This is a very early Phase 1 trial, so the main goal is safety, not effectiveness. Many drugs fail at this stage, and side effects are unknown. Results may not apply to all tumor types.
