New hope for rare, aggressive stomach cancer: drug combo aims to make tumors operable
NCT ID NCT07515625
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a combination of three drugs (sintilimab, bevacizumab, and chemotherapy) in people with a rare and aggressive type of stomach cancer that produces a protein called AFP. The goal is to shrink the tumors enough so they can be surgically removed. About 46 adults with advanced stomach cancer that has not spread too far will receive the treatment, and researchers will measure how many respond and can have successful surgery.
