New Dual-Targeting drug VBC106 takes aim at Hard-to-Treat cancers
NCT ID NCT07686068
First seen Jul 07, 2026 · Last updated Jul 10, 2026 · Updated 3 times
Summary
This trial tests an experimental drug called VBC106 in people with advanced solid tumors that have not responded to standard treatments. VBC106 is designed to target two proteins (FRα and MSLN) found on some cancer cells, delivering a toxic payload directly to the tumor. The study has two parts: first, finding the safest dose, and then testing how well that dose works in specific cancer types.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- VBC106 (a bispecific antibody drug conjugate targeting FRα and MSLN)
- What this could lead to
- If successful, VBC106 could offer a new treatment option for people with advanced solid tumors that have stopped responding to standard therapies.
- What could go wrong
- This is an early-phase trial (Phase 1/2a) with a small number of participants, so the drug may not prove effective or may cause significant side effects. It is too early to know if it will benefit patients broadly.
