First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This Phase II trial tests an experimental drug called QLS31905 combined with chemotherapy, with or without another drug (QL2107), in 120 people with advanced biliary tract cancer that has a specific protein (CLDN18.2). The goal is to see if the combination shrinks tumors. Participants must not have had prior treatment for advanced disease.

What this could mean

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

Active substance

QLS31905 (an experimental drug) combined with chemotherapy (gemcitabine, cisplatin, oxaliplatin, capecitabine) and possibly QL2107

What this could lead to

If successful, this could offer a new treatment option for people with advanced biliary tract cancer that has a specific marker (CLDN18.2).

What could go wrong

This is an early Phase II trial with only 120 people, so results may not apply to everyone. The drug combination may cause side effects or not work better than standard care.
