Immunotherapy plus chemo aims to shrink stomach tumors before surgery

NCT ID NCT07522151

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 3 trial tests whether adding the immunotherapy drug adebrelimab to standard chemotherapy (S-1 and oxaliplatin) works better than chemo alone for people with stomach or gastroesophageal junction cancer that can be surgically removed. About 874 participants will receive the treatment or a placebo before and after surgery. The study measures how long patients live without cancer returning and how well the tumor responds to treatment.

What this could mean

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

Active substance

Adebrelimab (an immunotherapy drug) plus S-1 and oxaliplatin (chemotherapy)

What this could lead to

If successful, this combination could become a new standard treatment to reduce cancer recurrence and improve survival for people with resectable gastric cancer.

What could go wrong

This is a large phase 3 trial, but immunotherapy can cause immune-related side effects. The benefit over standard chemo alone is not yet proven, and results may not apply to all patients.
