Can a Three-Drug cocktail shrink stomach tumors before surgery?
NCT ID NCT06447636
First seen Jul 24, 2026 · Last updated Aug 06, 2026 · Updated 2 times
Summary
This phase 2 trial is testing whether adding surufatinib (a targeted therapy that blocks blood vessel growth) to standard immunotherapy and chemotherapy can improve outcomes for people with locally advanced stomach or gastroesophageal junction cancer. The treatment is given before and after surgery to shrink the tumor and increase the chance of complete removal. The study will measure how many patients have no cancer cells left in the removed tissue (pathological complete response) and how long they remain cancer-free.
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 surufatinib (a kinase inhibitor), sintilimab (an immunotherapy), and chemotherapy (oxaliplatin and S1)
- What this could lead to
- If successful, this approach could improve tumor shrinkage before surgery and increase the chance of complete removal, potentially leading to better long-term survival for people with locally advanced gastric cancer.
- What could go wrong
- This is a small, early-phase trial with only 20 participants, so results may not apply broadly. The combination of drugs may cause significant side effects, and it is not yet known whether it will improve outcomes compared to standard treatment.
