NCT ID NCT05632939

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

Summary

This early-stage trial is testing a new drug called ASKB589, which targets a protein (CLDN18.2) found on some stomach cancer cells. It is given together with standard chemotherapy and an immunotherapy drug. The study includes 62 people with advanced stomach or gastroesophageal junction cancer that cannot be surgically removed. The main goals are to check safety, find the best dose, and see if the combination shrinks tumors.

What this could mean

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

Active substance

ASKB589 (a monoclonal antibody targeting CLDN18.2) combined with chemotherapy (oxaliplatin and capecitabine) and an immunotherapy (sintilimab or tislelizumab)

What this could lead to

If it works, this combination could offer a new first-line treatment option for people with advanced gastric cancer that cannot be removed by surgery.

What could go wrong

This is an early-phase trial with only 62 participants, so the main goal is safety and dosing—not yet proving the treatment works. Side effects from the drug combination could be serious.
