Can a targeted antibody boost chemotherapy for a rare bile duct cancer?

NCT ID NCT07723534

First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time

Summary

This phase 2 trial is testing whether adding zolbetuximab, an antibody that targets a protein called claudin 18.2, to standard chemotherapy can help control advanced or metastatic biliary tract cancers. The study enrolls adults whose tumors overexpress this protein. Participants receive zolbetuximab with either of two chemotherapy regimens for up to two years, and researchers track how long the cancer stays under control.

What this could mean

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

Active substance
zolbetuximab combined with chemotherapy (mFOLFOX6 or CAPOX)
What this could lead to
If successful, this combination could offer a new treatment option for people with advanced biliary tract cancers that have a specific protein marker.
What could go wrong
This is an early-phase trial with only 32 participants, so results may not apply broadly. Chemotherapy side effects and potential immune reactions to zolbetuximab are risks.
