Can a Three-Drug attack shrink stomach cancer in the abdomen?
NCT ID NCT06914687
First seen Jul 28, 2026 · Last updated Jul 29, 2026 · Updated 1 time
Summary
This trial tests whether combining an immunotherapy drug (tislelizumab) with standard chemotherapy and heated chemotherapy delivered directly into the abdomen can shrink tumors and improve survival in people with stomach cancer that has spread to the lining of the abdomen. The study enrolls 30 adults aged 18 to 75 with confirmed peritoneal metastases. Researchers will measure how many patients survive for one year and how many become eligible for complete surgical removal of their cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a combination of the immunotherapy drug tislelizumab, chemotherapy drugs S-1 and oxaliplatin, and heated chemotherapy (docetaxel or paclitaxel) delivered directly into the abdomen
- What this could lead to
- If successful, this approach could offer a new treatment option for people with stomach cancer that has spread to the lining of the abdomen, potentially improving survival and increasing the chance of successful surgery.
- What could go wrong
- This is a small, early-phase trial with only 30 participants and no comparison group, so results may not apply broadly. The combination of multiple strong treatments also raises the risk of serious side effects.
