Immunotherapy duo aims to shrink stomach tumors before surgery

NCT ID NCT06829797

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

Summary

This Phase 2 trial tests whether adding an immunotherapy drug (QL1706) to standard chemotherapy before and after surgery can improve outcomes for people with locally advanced stomach or gastroesophageal junction cancer. About 96 participants will be randomly assigned to receive either the combination or chemotherapy alone. The main goal is to see if the combination leads to a higher rate of complete tumor disappearance (pathological complete response) at the time of surgery.

What this could mean

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

Active substance

Iparomlimab and tuvonralimab (QL1706) combined with SOX chemotherapy

What this could lead to

If successful, this combination could become a new standard neoadjuvant treatment, potentially improving the chance of complete tumor removal and long-term control for locally advanced gastric cancer.

What could go wrong

This is an early Phase 2 trial with only 96 participants, so results may not be definitive. Adding immunotherapy to chemotherapy can increase side effects, and the benefit over chemotherapy alone is not yet proven.
