Can a Dual-Targeting drug shrink Hard-to-Treat tumors?
NCT ID NCT07772934
First seen Aug 19, 2026 · Last updated Aug 20, 2026 · Updated 1 time
Summary
This trial tests VBC117, an investigational drug designed to attach to two proteins found on tumor cells and deliver a toxic payload directly to them. The study enrolls adults with advanced or metastatic solid tumors that have not responded to standard treatments. The goal is to find the safest and most effective dose and to see whether VBC117 can shrink tumors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- VBC117, an experimental bispecific antibody-drug conjugate targeting EGFR and CDH17
- What this could lead to
- If successful, VBC117 could offer a new treatment option for people with advanced solid tumors that have not responded to standard therapies.
- What could go wrong
- This is an early-phase, first-in-human trial, so safety and effectiveness are not yet established. The drug may cause side effects or may not shrink tumors.
