New drug cocktail shows promise for tough esophageal cancer
NCT ID NCT07283991
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new drug called QL1706 combined with chemotherapy for people with a type of esophageal cancer that is hard to remove with surgery. The goal is to shrink the tumor enough so that surgery can be done successfully. 24 adults with this cancer will receive the drug combo before surgery, and then continue QL1706 after surgery to help keep the cancer from coming back.
