ClinConnect Summary

This clinical trial is studying the effects of two experimental treatments, durvalumab and tremelimumab, for patients with advanced liver cancer that cannot be surgically removed. These treatments are designed to help the body's immune system recognize and fight cancer more effectively. The trial will take place after patients receive a specific type of radiation therapy called radioembolization, which targets liver tumors with tiny particles. Researchers aim to understand how well these medications work and what side effects they may cause.

To participate, patients must have a confirmed diagnosis of unresectable liver cancer and meet certain health criteria, such as being able to provide informed consent and having a life expectancy of at least 12 weeks. Eligible participants will be closely monitored throughout the study and may receive the treatments for several weeks. It’s important for potential participants to discuss with their doctors whether they meet the eligibility requirements and understand what being part of the trial entails, including the commitment to follow-up visits and potential side effects.

• Exclusion Criteria:
• • Portal vein invasion at the main portal branch (Vp4), inferior vena cava, or cardiac involvement of hepatocellular carcinoma (HCC) based on imaging. Vascular invasion to portal vein side branches are eligible for study
• • Evidence of diffuse HCC (tumor burden occupying \> 50% of liver)
