Triple attack on stomach cancer: radiation, chemo, and a smart antibody

NCT ID NCT07689851

First seen Jul 08, 2026 · Last updated Jul 09, 2026 · Updated 1 time

Summary

This trial tests a new approach for people with advanced stomach or gastroesophageal junction cancer that cannot be removed by surgery. It combines standard chemotherapy (CAPOX) and radiation with an experimental drug called SHR-1701, which targets two proteins (PD-L1 and TGF-β) that help tumors hide from the immune system. The goal is to shrink tumors and improve survival, possibly making surgery an option later. The study includes about 60 adults aged 18 to 75 with HER2-negative disease.

What this could mean

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

Active substance
SHR-1701 (a bispecific antibody targeting PD-L1 and TGF-β)
What this could lead to
If successful, this combination could shrink tumors enough to allow surgical removal, potentially improving survival for people with advanced gastric cancer.
What could go wrong
This is an early-phase trial with only 60 participants. The treatment may cause side effects from radiation, chemotherapy, or the new drug, and it may not work for everyone.
