ClinConnect Summary

This clinical trial is investigating a new treatment for patients with locally advanced esophageal squamous cell carcinoma, a type of cancer affecting the esophagus. The study aims to combine a medication called Ivonescimab with standard chemotherapy to see if this combination can improve outcomes for patients who are scheduled for surgery. This is important because current treatments have a high chance of cancer returning after surgery, and researchers hope that this new approach will reduce that risk and improve survival rates.

To participate in this trial, individuals must have a confirmed diagnosis of locally advanced esophageal squamous cell carcinoma that can still be surgically removed. They should be aged between 18 and 75, have good overall health, and not have received previous cancer treatments. Participants will receive the combination therapy and will be closely monitored for safety and effectiveness. This trial is not yet recruiting, so interested individuals will need to wait for it to start and should discuss any questions with their healthcare provider.
