Immunotherapy plus chemo aims to fight bile duct cancer

NCT ID NCT04910386

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

Summary

This Phase 2 trial tests whether adding the immunotherapy drug envafolimab to standard chemotherapy (gemcitabine plus cisplatin) helps people with advanced biliary tract cancers live longer without their cancer growing. About 126 adults who have not had prior treatment for advanced disease will be randomly assigned to receive either the combo or chemo alone. The study is open-label, meaning both doctors and patients know which treatment is given.

What this could mean

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

Active substance

envafolimab (an immunotherapy drug) plus gemcitabine and cisplatin (chemotherapy)

What this could lead to

If it works, this could offer a more effective first-line treatment for advanced biliary tract cancers, potentially slowing disease progression.

What could go wrong

This is an early Phase 2 trial with only 126 participants, so results may not be conclusive. Immunotherapy can cause immune-related side effects, and the combination may not improve outcomes over standard chemo alone.
