New cocktail of drugs could shrink stomach tumors before surgery
NCT ID NCT07069712
First seen Jun 25, 2026 · Last updated Aug 18, 2026 · Updated 4 times
Summary
This study tests several new drug combinations given before and after surgery for stomach or esophageal cancer. About 100 people with resectable tumors will receive these treatments to see if they are safe and can shrink or eliminate the cancer. The goal is to improve outcomes by attacking the cancer more effectively before surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AZD0901, Rilvegostomig, Trastuzumab Deruxtecan, Capecitabine, 5-Fluorouracil, FLOT chemotherapy
- What this could lead to
- If successful, this could lead to better treatment options before surgery for stomach cancer, potentially improving survival and reducing recurrence.
- What could go wrong
- This is an early-phase trial with only 100 participants, so results may not apply to everyone. The new drug combinations may cause side effects or not work better than current treatments.
