New hope for tough cancers: experimental drug targets HER3 in advanced tumors

NCT ID NCT06956690

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

Summary

This study tests an experimental drug called HMBD-501 in 180 adults with advanced solid tumors (melanoma, lung, or breast cancer) that have a protein called HER3 on their cells and have stopped responding to standard treatments. The trial has two phases: first, finding the safest dose, then checking if the drug can shrink tumors. The goal is to control the disease, not cure it, as patients may need ongoing treatment.
