New cocktail of drugs shows promise for tough stomach cancer
NCT ID NCT05702229
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Phase 2 trial is testing several new drug combinations in people with advanced stomach or gastroesophageal junction cancer that cannot be removed by surgery or has spread. The study aims to see if these combinations can shrink tumors and keep them from growing for at least 6 months. About 163 participants will receive different combinations of immunotherapy and chemotherapy drugs.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Rilvegostomig, Volrustomig, FOLFOX, XELOX, AZD0901, 5-Fluorouracil, Capecitabine
- What this could lead to
- If successful, this could point toward more effective combination treatments for advanced gastric cancer, potentially improving tumor shrinkage and delaying disease progression.
- What could go wrong
- This is an early Phase 2 trial with a small number of participants, so results may not apply to all patients. The drug combinations may cause significant side effects or fail to show benefit.
