ClinConnect Summary

This clinical trial is studying a combination of treatments for patients with a type of liver cancer called intrahepatic cholangiocarcinoma, particularly those at high risk for the cancer returning after surgery. The trial will compare a new treatment regimen that includes a PD1 antibody (Toripalimab), along with lenvatinib and GEMOX chemotherapy, to the standard surgical treatment currently used. Researchers hope that this new approach will improve the chances of patients being free from cancer after surgery.

To be eligible for the trial, participants must be between 18 and 70 years old, have a confirmed diagnosis of intrahepatic cholangiocarcinoma, and have certain high-risk factors like larger tumor size or signs of spread. Participants can expect to receive either the new treatment or the standard care, and they will be closely monitored throughout the study. It’s important to know that there are specific health criteria that need to be met to join, and potential participants should discuss this with their healthcare provider to see if they qualify.
